'Super-resolution' microscope possible for nanostructures

Apr. 29, 2013 ? Researchers have found a way to see synthetic nanostructures and molecules using a new type of super-resolution optical microscopy that does not require fluorescent dyes, representing a practical tool for biomedical and nanotechnology research.

"Super-resolution optical microscopy has opened a new window into the nanoscopic world," said Ji-Xin Cheng, an associate professor of biomedical engineering and chemistry at Purdue University.

Conventional optical microscopes can resolve objects no smaller than about 300 nanometers, or billionths of a meter, a restriction known as the "diffraction limit," which is defined as half the width of the wavelength of light being used to view the specimen. However, researchers want to view molecules such as proteins and lipids, as well as synthetic nanostructures like nanotubes, which are a few nanometers in diameter.

Such a capability could bring advances in a diverse range of disciplines, from medicine to nanoelectronics, Cheng said.

"The diffraction limit represents the fundamental limit of optical imaging resolution," Cheng said. "Stefan Hell at the Max Planck Institute and others have developed super-resolution imaging methods that require fluorescent labels. Here, we demonstrate a new scheme for breaking the diffraction limit in optical imaging of non-fluorescent species. Because it is label-free, the signal is directly from the object so that we can learn more about the nanostructure."

Findings are detailed in a research paper that appeared online Sunday (April 28) in the journal Nature Photonics.

The imaging system, called saturated transient absorption microscopy,or STAM,uses a trio of laser beams, including a doughnut-shaped laser beam that selectively illuminates some molecules but not others. Electrons in the atoms of illuminated molecules are kicked temporarily into a higher energy level and are said to be excited, while the others remain in their "ground state." Images are generated using a laser called a probe to compare the contrast between the excited and ground-state molecules.

The researchers demonstrated the technique, taking images of graphite "nanoplatelets" about 100 nanometers wide.

"It's a proof of concept and has great potential for the study of nanomaterials, both natural and synthetic," Cheng said.

The doughnut-shaped laser excitation technique, invented by researcher Stefan Hell, makes it possible to focus on yet smaller objects. Researchers hope to improve the imaging system to see objects about 10 nanometers in diameter, or about 30 times smaller than possible using conventional optical microscopes.

"We are not there yet, but a few schemes can be applied to further increase the resolution of our system," Cheng said.

The paper was co-authored by biomedical engineering doctoral student Pu Wang; research scientist Mikhail N. Slipchenko; mechanical engineering doctoral student James Mitchell; Chen Yang, an assistant professor of physical chemistry at Purdue; Eric O. Potma, an associate professor of chemistry at the University of California, Irvine; Xianfan Xu, Purdue's James J. and Carol L. Shuttleworth Professor of Mechanical Engineering; and Cheng.

Future research may include work to use lasers with shorter wavelengths of light. Because the wavelengths are shorter, the doughnut hole is smaller, possibly allowing researchers to focus on smaller objects.

The work will be discussed during the third annual Spectroscopic Imaging: A New Window into the Unseen World workshop on May 23 and 24 at Purdue. The workshop is hosted by the university's Weldon School of Biomedical Engineering.

The research is funded by the National Institutes of Health, National Science Foundation and the Defense Advanced Research Projects Agency.

How Buckminster Fuller's Dymaxion Map Tessellated The World

Buckminster Fuller applied his patented Dymaxion brand to all sorts of objects over the course of his career, from cars to buildings to entire cities. But one of the most useful and enduring applications? The Dymaxion World map, which unfolds the earth into a long string of shapes, like a carefully peeled orange.

2013 marks the map?s 70th birthday, and to celebrate, the Brooklyn-based Buckminster Fuller Institute launched Dymax Redux, competition to redesign updated versions of the map. The winners will be unveiled sometime this fall, but in the meantime, it's worth taking a look back at some of the awesomely tessellated Dymaxion spinoffs that already exist.

First, a bit of background. What makes the Dymaxion World map so enduring? It?s a brilliant mathematical object. Fuller?s projection bears far less distortion than other flat maps, like the Mercator projection or the Peters projection, and it divides up the globe into a contiguous surface without dividing any of its land masses. Because it isn?t a traditional ?shadow? projection it?s not distorted on one axis or another, so you can read it from any orientation and rearrange its contents in any number of ways.

But it?s the Dymaxion?s distinctly optimistic point of view that makes it so unique. Patented at the end of World War II, it shows us all five continents as a single archipelago, or "one island in one ocean.? It took him decades of tinkering to figure out the right projection, but it was important to him that we see the earth as a single, interconnected network. ?For the layman, engrossed in belated, war-taught lessons in geography, the Dymaxion World map is a means by which he can see the whole world fairly and all at once,? explained LIFE magazine when it published the map in 1943. The writers at LIFE also found a way to rearrange the map to articulate a bit of wartime racism against Japan: "The ruthless logic of Jap imperialism is exposed by this layout,? the editors continued. ?Their thinking strikes an obvious contrast to the landlubber geopolitics of their German allies.? Well then!

Fuller probably disapproved of the way LIFE twisted his map into something aggressive, but that?s a perfect example of how maps can become socio-political weapons?and why he thought we needed to retool them. Fuller intended the Dymaxion World map to serve as a tool for communication and collaboration between nations. ?If you want to teach people a new way of thinking, don't bother trying to teach them,? he famously said. ?Instead, give them a tool, the use of which will lead to new ways of thinking.?

Did the map lead to a new world order? Not exactly?but did lead to a revolution in mapping. More about Dymax Redux is here, but in the meantime, check out eight other interesting applications of Fuller's projection below.

No-Hassle Systems Of Crock Pot Recipes For 2012 | Unlock iPhone 4

Article by Melba L. A. Rowland-Benavides ? Do you need some quick tips about what regarding Crock Pot Recipes as well as pork tenderloins? Do you have questions on the kind of food preparation methods that are suitable with regard to pork chops and also pork tenderloins?

Cooking food pork may be an extremely challenging point. Undercooking it?s really a main hazard to health as well as over cooking food leaves the meats dried out and with simply no flavor. Nobody wants you can eat both of these therefore it is extremely important that you pay attention to cooking times as well as select the most practical method for that reduce of beef you?ve. Pig should invariably be cooked to a inside heat regarding 160 degrees. pork chop recipes might be a harder to tell doneness because it is already white. Along with ground beef, it is possible to inform the done if it is will no longer red inside, but its different together with pig. This is the reason it is good to use a thermometer.

A single main suggestion that will assist using the meats not really becoming dry is something known as relaxing. If you are accustomed to food preparation large cuts associated with meats, you may be acquainted with this kind of term. This is where you allow the beef take a seat as well as rest for a tiny but after you cook that. Perhaps you have cut into a piece of meat and the fruit drinks emerged drained all over your menu? The reason is once the beef will be cooking, the particular fruit juices are hot and therefore are operating throughout within the meats. Once you get forced out, every one of the juices redistribute as well as reconcile back. This can really help with all the pain because the fruit drinks will remain inside of. This is a good idea to pay for the meats with a bit of foil or even a lighted so that it doesn?t get cool even though it is relaxing.

There are numerous types approaches to prepare Dinner Recipes. For the smaller sized slashes of meats, saut?ing may be the way to go. This is where you add tiny pieces inside a skillet as well as move these around rapidly as they prepare over a high temperature. Grilling is among my personal favorite methods and can be employed for more compact reductions like the chops, but could also be employed for larger slashes just like the loin roast. How you can carry out the loin roasts is via what is called roundabout barbecuing. This is extremely similar to what goes on within an oven. You?d hold the beef on one side of the bbq grill as well as the fireplace on the other half. In contrast to traditional cooking, the actual beef is not immediately within the flare.

Surviving hell in a Bangladesh factory collapse

SAVAR, Bangladesh (AP) ? Merina was so tired. It had been three days since the garment factory where she worked had collapsed around her, three days since she'd moved more than a few inches. In that time she'd had nothing to eat and just a few sips of water. The cries for help had long since subsided. The moans of the injured had gone silent.

It was fatigue she feared the most. If sleep took her, Merina was certain she would never wake up.

"I can't fall asleep," the 21-year-old thought to herself, her face inches from a concrete slab that had once been the ceiling above her. She'd spent seven years working beneath that ceiling, sewing T-shirts and pants destined for stores from Paris to Los Angeles. She worked 14 hours a day, six days a week, with her two sisters. She made the equivalent of about $16 a week.

Now she lay on her back in the sweltering heat, worrying for her sisters and herself. And as the bodies of her former coworkers began to rot, the stench filled the darkness.

____

The eight-story, concrete-and-glass Rana Plaza was one of hundreds of similar buildings in the crowded, potholed streets of Savar, an industrial suburb of Bangladesh's capital and the center of the country's $20 billion garment industry. If Bangladesh remains one of the world's poorest nations, it is no longer a complete economic cripple. Instead, it turned its poverty to its advantage, heralding workers who make some of the world's lowest wages and attracting some of the world's leading brands.

But this same economic miracle has plunged Bangladesh into a vicious descending spiral of keeping down costs, as major retailers compete for customers who want ever cheaper clothes. It is the workers who often pay the price in terms of safety and labor conditions.

The trouble at Rana Plaza began Tuesday morning, when workers spotted long cracks in at least one of the building's concrete pillars. The trails of chipped plaster led to a chunk of concrete, about the size of a shoe box, that had broken away. The police were called. Inspectors came to check on the building, which housed shops on the lower floors and five crowded clothing factories on the upper ones.

At 10 a.m., the 3,200 garment workers were told to leave early for lunch. At 2 p.m., they were told to leave for the day. Few of the workers ? mostly migrants from desperately poor villages ? asked why. Some were told the building had unexplained electricity issues.

The best factory buildings are well-constructed and regularly inspected. The workers are trained what to do in case of an emergency.

Rana Plaza was not one of those buildings. The owner, Mohammed Sohel Rana, was a feared neighborhood political enforcer who had branched into real estate. In 2010, he was given a permit to build a five-story building on a piece of land that had once been a swamp. He built eight stories.

Rana came quickly after the crack was found. So did the police, some reporters and officials from the country's largest garment industry association.

Rana refused to close the building. "There is nothing serious," he said. The workers were told to return the next morning, as scheduled, at 8 a.m.

____

Merina, a petite woman with a round, girlish face and shoulder-length hair, never saw the crack.

She comes from Biltala, a tiny village in southwest Bangladesh, where there is electricity but little else. Her father is a landless laborer who grows rice and wheat on rented farmland, and, when he can, travels the seven hours by train to Dhaka to sell cucumbers, cauliflower and other vegetables on the street. When she was 15, she moved to Dhaka. Some of her aunts were already working in garment factories, and she quickly had a job.

For millions of Bangladeshis, the garment factories of Dhaka are a dream. Every year, at least 300,000 rural residents ? and perhaps as many as 500,000 ? migrate to the Dhaka area, already one of the most crowded cities on the planet.

Poverty remains the norm across most of rural Bangladesh, where less than 60 percent of adults are literate. To them, the steady wage of a garment factory ? even with minimum wage less than $40 a month ? is enough to start saving up for a scooter, or a dowry, or a better school for the next generation.

Merina's two sisters joined her in Savar, where women make up the vast majority of the factory workers. Here, the poor learn quickly that it is not their role to question orders. And girls learn quickly that nearly all decisions are made by men.

So for a woman like Merina, who like many Bangladeshis goes by one name, there are generations of culture telling her not to question a command to go back to work.

When some factory workers did speak up Wednesday morning, they were reminded that the end of the month ? and their paychecks ? was near. The message was clear: If you don't work, you won't get paid.

"Don't speak bullshit!" a factory manager told a 26-year-old garment worker named Shama, she said, when she worried about going inside. "There is no problem."

____

Around 8:40 a.m. Wednesday, when the factories had been running for 40 minutes or so, the lights suddenly went off in the building. It was nothing unusual. Bangladesh's electricity network is poorly maintained and desperately overburdened. Rana Plaza, like most of the factories in the area, had its own backup generator, sometimes used dozens of times in a single day.

A jolt went through the building when the generator kicked on. Again, this was nothing unusual. Eighteen-year-old Baezid was chatting with a friend as they checked an order of short-sleeved shirts.

He'd come from the countryside with his family ? mother, father and two uncles ? just seven months earlier. Since then, he'd worked seven days a week, from 8 a.m. to midnight. His salary was about $55 a month. But he could more than double that by working so many hours, since overtime pays .37 cents an hour.

Sometime after the generator switched on ? perhaps a few moments later, perhaps a few minutes ? another, far larger, jolt shook the floor violently. The building gave a deafening groan.

The pillars fell first, and one slammed against Baezid's back. He was knocked to the floor, and found himself pinned from the waist down, unable to move.

He heard coworkers crying in the darkness. One coworker trapped nearby had a mobile phone, and the seven or eight people nearby took turns to call their families.

Baezid wept into the phone. "'Rescue me!'" he begged them.

Like a young boy, he kept thinking of his mother. He wanted to see her again.

____

In Bangladesh, people in need of help rarely think first of the police, or firefighters, or anyone else official.

Baezid called his family. So did many other people. The state is so dysfunctional here, so riven by corruption and bad pay and incompetence, that ordinary people know they have a better chance of finding help by reaching out to their families. Often, they simply call out for the help of whoever will come.

Until Monday, when there was no hope left for survivors and heavy equipment was brought in to move tons of concrete, many of the rescuers working inside the rubble were volunteers. They were garment workers, or relatives of the missing. Or, in the case of Saiful Islam Nasar, they were just a guy from a small town who heard people needed help.

Nasar, a lanky mechanical engineer from a town about 300 kilometers (185 miles) away, runs a small volunteer association. They get no funding and have no training. They buy their supplies themselves. For the most part, the group offers first aid to people who have been in car accidents. During the monsoon rains, they help whoever they can as the waters rise around the town.

When he saw the news, Nasar gathered 50 men, jumped on a train and reached Rana Plaza about 11 hours after the collapse.

He made his way into the rubble with a hammer and a hacksaw, by the light of his mobile phone. In six days, he says he has rescued six people, and helped carry out dozens of bodies.

That first night, he slept on the roof of the collapsed building. Then for two nights he slept in a field, and now he has a tent. But he can't sleep much anyway, because the images of all the corpses keep running through his head.

Told that he was a hero, he looked back silently.

Then he wept.

____

Merina was sitting at her knitting machine on the fourth floor, in the Phantom TAC factory, when the world seemed to explode.

She jumped to her feet and tried to run for the door, but pieces of the ceiling slammed down on her. She crawled in search of a place to hide, and found one: a section of the upstairs floor had crashed onto two toppled pillars, creating a small protected area. About 10 other men and women had the same idea, including Sabina, a close friend. The two women clutched hands and wept, thinking their lives would end in a concrete tomb. "We're going to die, we're going to die," they said to each other.

The group could barely move in the tiny space. Merina's yellow salwar kameez was drenched with sweat. The air was putrid with the smell of death.

As time passed, desperately thirsty survivors began drinking their own urine. One person found a fallen drum of water used for ironing and passed around what was left in a bottle cap. Merina sipped gratefully.

She kept thinking of her sisters, who shared a single bed with her in a corrugated tin-roofed room near the factory.

Her sisters, though, had been luckier.

Merina's older sister, Sharina, ran out just in time. She turned around to watch the building she had toiled in for years fold onto itself in an instant.

"I must be no longer on this earth," she thought, her hands covering her ears from the deafening boom. After a frantic search, she found 16-year-old Shewli, who had also escaped. But where was Merina? She borrowed a cell phone and called her father in their village. "I managed to escape, but Merina is still trapped," she told him.

Their parents booked tickets on the next train to Dhaka.

They arrived Thursday morning, joining hundreds of other relatives who had thronged to the scene. Merina's mother prayed hard, promising God a devotional offering ? a valuable gift from this rural family ? if Merina got out alive.

"If you save the life of my daughter, I will sacrifice a goat for you," she promised.

____

On Friday, Merina finally began to hear the sounds of rescuers cutting through the slab above her with concrete saws.

"Save us! Save us!" she and Sabina yelled together. But by the time the rescuers reached her Saturday morning, she was disoriented and barely conscious. She was put in an ambulance and people surrounded her. "Where are you taking me?" she asked them. "What happened?"

"Don't be afraid, you're going to the hospital," someone told her.

Merina was taken to the Enam Medical College Hospital, a bare-bones facility with aged, rusted beds, dirty tile floors and bare concrete walls. After everything that happened, she had emerged with just bumps on her head and a sore back from lying in the same constrained position for so long. Baezid woke up in the same hospital, relatively unhurt except for a huge bruise from the pillar, which had turned his back almost black.

At least 386 people died, and the toll is climbing. Building owner Rana has been arrested.

On Saturday, as Merina lay on her side resting, her mother stroked her hair, fed her and rubbed her back. Tears rolled down Merina's face, and she squeezed her father's hand.

That night, Merina slept fitfully, replaying the ordeal in her mind. She woke with a new conviction. "God has given me a second life," Marina said later, speaking from her hospital bed. "When I've recovered, I will return home and I will never work in a garment factory again." Baezid said the same thing: He'd never go back to the garment factories.

Many survivors, though, will return. The choices are just too few.

____

Baezid's two uncles also worked in Rana Plaza. The three went to the factories together last Wednesday.

The two uncles have not been seen since. They are presumed dead.

He'd come from the countryside with his family ? mother, father and two uncles ? just seven months earlier. Since then, he'd worked seven days a week, from 8 a.m. to midnight. His salary was about $55 a month. But he could more than double that by working so many hours, since overtime pays .37 cents an hour.

Sometime after the generator switched on ? perhaps a few moments later, perhaps a few minutes ? another, far larger, jolt shook the floor violently. The building gave a deafening groan.

The pillars fell first, and one slammed against Baezid's back. He was knocked to the floor, and found himself pinned from the waist down, unable to move.

He heard coworkers crying in the darkness. One coworker trapped nearby had a mobile phone, and the seven or eight people nearby took turns to call their families.

Baezid wept into the phone. "'Rescue me!'" he begged them.

Like a young boy, he kept thinking of his mother. He wanted to see her again.

____

In Bangladesh, people in need of help rarely think first of the police, or firefighters, or anyone else official.

Baezid called his family. So did many other people. The state is so dysfunctional here, so riven by corruption and bad pay and incompetence, that ordinary people know they have a better chance of finding help by reaching out to their families. Often, they simply call out for the help of whoever will come.

Until Monday, when there was no hope left for survivors and heavy equipment was brought in to move tons of concrete, many of the rescuers working inside the rubble were volunteers. They were garment workers, or relatives of the missing. Or, in the case of Saiful Islam Nasar, they were just a guy from a small town who heard people needed help.

Nasar, a lanky mechanical engineer from a town about 300 kilometers (185 miles) away, runs a small volunteer association. They get no funding and have no training. They buy their supplies themselves. For the most part, the group offers first aid to people who have been in car accidents. During the monsoon rains, they help whoever they can as the waters rise around the town.

When he saw the news, Nasar gathered 50 men, jumped on a train and reached Rana Plaza about 11 hours after the collapse.

He made his way into the rubble with a hammer and a hacksaw, by the light of his mobile phone. In six days, he says he has rescued six people, and helped carry out dozens of bodies.

That first night, he slept on the roof of the collapsed building. Then for two nights he slept in a field, and now he has a tent. But he can't sleep much anyway, because the images of all the corpses keep running through his head.

Told that he was a hero, he looked back silently.

Then he wept.

____

Merina was sitting at her knitting machine on the fourth floor, in the Phantom-TAC factory, when the world seemed to explode.

She jumped to her feet and tried to run for the door, but pieces of the ceiling slammed down on her. She crawled in search of a place to hide, and found one: a section of the upstairs floor had crashed onto two toppled pillars, creating a small protected area. About 10 other men and women had the same idea, including Sabina, a close friend. The two women clutched hands and wept, thinking their lives would end in a concrete tomb. "We're going to die, we're going to die," they said to each other.

The group could barely move in the tiny space. Merina's yellow salwar kameez was drenched with sweat. The air was putrid with the smell of death.

As time passed, desperately thirsty survivors began drinking their own urine. One person found a fallen drum of water used for ironing and passed around what was left in a bottle cap. Merina sipped gratefully.

She kept thinking of her sisters, who shared a single bed with her in a corrugated tin-roofed room near the factory.

Her sisters, though, had been luckier.

Merina's older sister, Sharina, ran out just in time. She turned around to watch the building she had toiled in for years fold onto itself in an instant.

"I must be no longer on this earth," she thought, her hands covering her ears from the deafening boom. After a frantic search,, she found 16-year-old Shewli, who had also escaped. But where was Merina? She borrowed a cell phone and called her father in their village. "I managed to escape, but Merina is still trapped," she told him.

Their parents booked tickets on the next train to Dhaka.

They arrived Thursday morning, joining hundreds of other relatives who had thronged to the scene. Merina's mother prayed hard, promising God a devotional offering ? a valuable gift from this rural family ? if Merina got out alive.

"If you save the life of my daughter, I will sacrifice a goat for you," she promised.

____

On Friday, Merina finally began to hear the sounds of rescuers cutting through the slab above her with concrete saws.

"Save us! Save us!" she and Sabina yelled together. But by the time the rescuers reached her Saturday morning, she was disoriented and barely conscious. She was put in an ambulance and people surrounded her. "Where are you taking me?" she asked them. "What happened?"

"Don't be afraid, you're going to the hospital," someone told her.

Merina was taken to the Enam Medical College Hospital, a bare-bones facility with aged, rusted beds, dirty tile floors and bare concrete walls. After everything that happened, she had emerged with just bumps on her head and a sore back from lying in the same constrained position for so long. Baezid woke up in the same hospital, relatively unhurt except for a huge bruise from the pillar, which had turned his back almost black.

At least 382 others died, and the toll is climbing. Building owner Rana has been arrested.

On Saturday, as Merina lay on her side resting, her mother stroked her hair, fed her and rubbed her back. Tears rolled down Merina's face, and she squeezed her father's hand.

That night, Merina slept fitfully, replaying the ordeal in her mind. She woke with a new conviction. "God has given me a second life," Marina said later, speaking from her hospital bed. "When I've recovered, I will return home and I will never work in a garment factory again." Baezid said the same thing: He'd never go back to the garment factories.

Many survivors, though, will return. The choices are just too few.

____

Baezid's two uncles also worked in Rana Plaza. The three went to the factories together last Wednesday.

The two uncles have not been seen since. They are presumed dead.

Shape-shifting mobile devices

Apr. 28, 2013 ? Prototype mobile devices that can change shape on-demand will be unveiled today [Monday 29 April] and could lay down the foundation for creating high shape resolution devices of the future.

The research paper, to be presented at one of the world's most important conferences on human-computer interfaces, will introduce the term 'shape resolution' and its ten features, to describe the resolution of an interactive device: in addition to display and touch resolution.

The research, led by Dr Anne Roudaut and Professor Sriram Subramanian, from the University of Bristol's Department of Computer Science, have used 'shape resolution' to compare the resolution of six prototypes the team have built using the latest technologies in shape changing material, such as shape memory alloy and electro active polymer.

One example of a device is the team's concept of Morphees, self-actuated flexible mobile devices that can change shape on-demand to better fit the many services they are likely to support.

The team believe Morphees will be the next generation of mobile devices, where users can download applications that embed a dedicated form factor, for instance the "stress ball app" that collapses the device in on itself or the "game app" that makes it adopt a console-like shape.

Dr Anne Roudaut, Research Assistant in the Department of Computer Science's Bristol Interaction and Graphics group, said: "The interesting thing about our work is that we are a step towards enabling our mobile devices to change shape on-demand. Imagine downloading a game application on the app-store and that the mobile phone would shape-shift into a console-like shape in order to help the device to be grasped properly. The device could also transform into a sphere to serve as a stress ball, or bend itself to hide the screen when a password is being typed so passers-by can't see private information."

By comparing the shape resolution of their prototypes, the researchers have created insights to help designers towards creating high shape resolution Morphees.

In the future the team hope to build higher shape resolution Morphees by investigating the flexibility of materials. They are also interested in exploring other kinds of deformations that the prototypes did not explore, such as porosity and stretchability.

Obama pokes fun at himself at Correspondents' Dinner

WASHINGTON (AP) ? President Barack Obama joked Saturday about his plans for a radical second-term evolution from a "strapping young Muslim Socialist" to retiree golfer, all with a new hairstyle like first lady Michelle's.

Obama used this year's annual White House Correspondents' Association dinner to poke fun at himself and some of his political adversaries, asking if it was still possible to be brought down a peg after 4? years as commander-in-chief.

Entering to the rap track "All I Do Is Win" by DJ Khaled, Obama joked about how re-election would allow him to unleash a radical agenda. But then he showed a picture of himself golfing on a mock magazine cover of "Senior Leisure."

"I'm not the strapping young Muslim Socialist that I used to be," the president remarked, and then recounted his recent 2-for-22 basketball shooting performance at the White House Easter Egg hunt.

But Obama's most dramatic shift for the next four years appeared to be aesthetic. He presented a montage of shots featuring him with bangs similar to those sometimes sported by his wife.

Obama closed by noting the nation's recent tragedies in Massachusetts and Texas, praising Americans of all stripes from first responders to local journalists for serving the public good.

Saturday night's banquet not far from the White House attracted the usual assortment of stars from Hollywood and beyond. Actors Kevin Spacey, Julia Louis-Dreyfus and Claire Danes, who play government characters on series, were among the attendees, as was Korean entertainer Psy. Several Cabinet members, governors and members of Congress were present.

And despite coming at a somber time, nearly two weeks after the deadly Boston Marathon bombing and 10 days after a devastating fertilizer plant explosion in West, Texas, the president and political allies and rivals alike took the opportunity to enjoy some humor. Late-night talk-show host Conan O'Brien headlined the event.

Some of Obama's jokes came at his Republican rivals' expense. He asked that the GOP's minority outreach begin with him as a "trial run" and said he'd take his recent charm offensive with Republicans on the road, including to a book-burning event with Rep. Michele Bachmann.

Casino magnate Sheldon Adelson would have had better success getting Obama out of office if he simply offered the president $100 million to drop out of last year's race, Obama quipped.

And on the 2016 election, the president noted in self-referential irony that potential Republican candidate Sen. Marco Rubio wasn't qualified because he hasn't even served a full term in the Senate. Obama served less than four years of his six-year Senate term before he was elected president in 2008.

The gala also was an opportunity for six journalists, including Associated Press White House Correspondent Julie Pace, to be honored for their coverage of the presidency and national issues.

The New Yorker's Ryan Lizza won the Aldo Beckman Award, which recognizes excellence in the coverage of the presidency.

Pace won the Merriman Smith Award for a print journalist for coverage on deadline.

ABC's Terry Moran was the winner of the broadcast Merriman Smith Award for deadline reporting.

Reporters Jim Morris, Chris Hamby and Ronnie Greene of the Center for Public Integrity won the Edgar A. Poe Award for coverage of issues of national significance.

Space coffee, just the way you like it - Gizmag

Since the early days of space travel, a consistent complaint has been bad coffee. Now a group of freshman engineering students at Rice University has developed a simple approach to alleviating this problem.

Hot coffee has been a part of space travel since the beginning of the Apollo program, which included a source of hot water for reconstituting food and drink. There are now many versions available, all freeze-dried and reconstituted using hot water at 70 degrees Celsius (158 degrees Fahrenheit).

Astronauts can choose from ordinary coffee (leaded or unleaded) and Kona coffee. It comes black, with artificial sweetener, with cream(er), with both, with sugar, or with cream(er) and sugar. And it all tastes bad.

"The key to freeze-dried food is Tabasco sauce."

The above quote is from a hiker and hunter, but is apropos here. Although modern freeze drying methods have greatly improved the taste of freeze-dried food and drink, even on Earth such foodstuffs are widely regarded as providing only a limited imitation of the taste experience that goes with ingesting "real" food and drink. Freeze-drying can cause the loss of some of the more volatile aroma compounds, thereby altering the taste. In addition, changes in texture during the freeze-drying process can alter the experience of eating a particular food. Tabasco sauce and similar condiments and additives can kick the flavor up a notch.

An additional factor in our appreciation of food and drink is related to the well-known psychological phenomenon of the Uncanny Valley. The Uncanny Valley is a concept used to explain why humanoid robots are so difficult to accept. If a robot is only vaguely humanoid, we take it for what it is. However, if it is close enough to appearing human, we concentrate on every aspect that makes it appear non-human, with the usual result being a "creepy" feeling.

A similar phenomenon takes place in food and drink. A processed food with a dramatically altered gustatory experience can be evaluated on its own merits. However, a processed food that is nearly correct will be perceived in terms of its difference from the ideal. In this case, the food will generally be perceived as "off" or on the verge of being spoiled. Sometimes food that is a bad imitation of some ideal food will be preferred to a fair to good imitation.

Culinary challenges in space

Do food and drink taste the same when you're in a small weightless capsule in orbit? In a word, no. The reaction of our taste buds is limited to five sensory responses (bitter, salty, sour, sweet and umami), but the experience of eating or drinking is strongly affected by a number of other sensory modes. These would include smell, texture, temperature, and chemesthesis (through which we gain the sensation of piquant flavors from chili peppers, black pepper, ginger, and horseradish). Of these, the sense of smell has perhaps the strongest influence on the experience of eating and drinking, and is particularly known to evoke old memories of events associated with similar odors.

The effect of weightlessness on the taste experience results from at least two physical effects. When sampling food on Earth, the aroma molecules from warm food are carried quickly into the nasal cavity by thermally-driven convection and turbulent flow. The main mechanism is that hot gas rises, and cool gas falls ? a process driven by gravity. However, in weightlessness thermally-driven motion of gases is much slower than on the ground. In the absence of the odors of food, the experience of the taste of food is greatly suppressed.

The second effect of weightlessness is that fluids within the body are not pulled into the lower body by gravity. As a result, fluids accumulate in the astronauts' upper body, so that they chronically suffer severely stuffy noses. We are all acquainted with how bland food tastes during the course of a cold, but for astronauts the cold doesn't go away.

Space coffee

"Moderation in all things" is a general guideline for life that apparently originated with the Ancient Greek philosopher Aristotle. When it comes to coffee, NASA may have gone missing that day in school. Black coffee is difficult to ruin, although the freeze-drying process does change the taste. However, there is a particular problem with premixed NASA coffee with additives. If you want sugar and/or creamer in your premixed NASA coffee, the result is a cuppa rendered syrupy with huge amounts of these additives. Astronauts complain more about the artificially large viscosity than about the taste, but both receive failing grades.

Rice University students, from left, Robert Johnson, Benjamin Young and Colin Shaw show their coffee as you like it for astronauts aboard the International Space Station

Among the goals of the Texas Space Grant Consortium (TSGC) is to provide opportunities for undergraduate students to participate in space based research and exploration. One mechanism for implementing this goal is the TSGC Design Challenge. Designing a ?coffee the way you like it? system for the use of astronauts on the International Space Station was one of the 2013 Challenges taken up by a trio of Rice University engineering students (Robert Johnson, Colin Shaw and Benjamin Young) and their faculty sponsors, Drs. Ann Saterbak and Matthew Wettergreen of Rice's Bioengineering department.

The challenge was to develop a method and equipment that allows astronauts to add liquid ingredients (cream, sweetener, and lemon juice) from a foil package to another that contains black coffee or tea. No spills in microgravity can be allowed, as these have a tendency to migrate into equipment and cause faults.

The Rice freshmen designed their system around the existing black coffee pouches. NASA supplied them two-ply heat sealed pouches to hold the sugar syrup and cream. The beverage and condiment pouches all have a septum which allows access to their contents without allowing any of the liquid contents to escape.

How is the new system used to make coffee with sugar? In use (see the video below), hot water is injected from a pistol-like dispenser through a septum into a coffee pouch and a sugar pouch. After dissolving the contents, a roller mechanism similar to those used to dispense all the toothpaste out of a toothpaste tube is engaged on the sugar pouch. The rollers were made on a 3-D printer.

To prepare coffee with sugar, a pouch to pouch drinking tube is inserted into the coffee and sugar pouches through their respective septums. A few cranks on the roller, and the coffee has just the right amount of sugar. The drinking tube is clamped shut, the contents of the coffee pouch are mixed by squeezing the pouch repeatedly, and then the drinking tube is unclamped so the astronaut can drink the coffee made to order. The spare sugar and creamer can be stored for later use.

Revive Old, Smelly Wooden Spoons with a Few Simple Tricks

Over time, wooden spoons absorb the various foods they come in contact with and start smelling funky. Luckily, it is possible to de-stink them and extend their lifespan.

Chow suggests several options to revive your old spoons. Before trying anything else, boil the spoon in a pot of water, and then set it outside in the sun for a few hours. Failing that, a deep scrubbing with dish soap or or a bath in vinegar solution might do the trick. If the smell still won't go away, you could put the spoon in a bag with activated charcoal, scrub it with a lemon, sandpaper off the top layer of wood, or even kill the bacteria with bleach. Clearly, there's no shortage of ways to give an old spoon new life. I probably wouldn't spend half a day trying each method before replacing it, but it's worth exhausting a few options before you throw it away for good.

Be sure to check out the source link, where Chow commenters have several other suggestions for reviving your cookware.

Four arrested as Bangladesh building toll rises to 352

DHAKA (Reuters) - Two factory bosses and two engineers were detained in Bangladesh on Saturday, three days after the collapse of a building where low-cost garments were made for Western brands killed at least 352 people. More were being pulled alive from the rubble at the building, where police said as many as 900 people were still missing in Bangladesh's worst ever industrial accident.

Iranian scientist freed by U.S. returns home: local media

DUBAI (Reuters) - An Iranian scientist held for more than a year in California on charges of violating U.S. sanctions arrived in Iran on Saturday, Iranian media reported, after being freed in what the Omani foreign ministry said was a humanitarian gesture. Mojtaba Atarodi, 55, an assistant professor of electrical engineering at Iran's Sharif University of Technology, had been detained on suspicion of buying high-tech U.S. laboratory equipment, previous Iranian media reports said.

Palestinians' Abbas says to start talks on unity government

RAMALLAH (Reuters) - Palestinian President Mahmoud Abbas said on Saturday he would begin talks with rival factions including Islamist Hamas to form a unity government, a crucial step towards healing years of damaging internal divisions. But, underscoring the chasm between Abbas's Fatah movement and Hamas, Hamas spokesman Sami Abu Zuhri said Abbas had not consulted his group about his move and the Islamists had only heard about it in media reports.

Militants kill five Iraqi soldiers, Sunni protesters form "army"

RAMADI, Iraq (Reuters) - Militants shot dead five Iraqi soldiers in the Sunni Muslim stronghold province of Anbar on Saturday and protesters said they were forming an "army" after four days of unrest that raised fears of a return to widespread sectarian civil conflict. More than 170 people have been killed since Tuesday when security forces stormed a Sunni protest camp in the town of Hawija, triggering clashes that spread to other Sunni areas in western and northern areas.

Ten dead, dozens hurt during Mexican prison riot

MEXICO CITY (Reuters) - Ten people were killed and dozens wounded in a prison riot early Saturday in the central state of San Luis Potosi, local officials said. State police said they had re-established control in an cell block of La Pila prison in the state capital of San Luis Potosi after a fight broke out between prisoners, according to a posting on the security ministry's official social media page.

German SPD leader woos Greens for anti-Merkel alliance

BERLIN (Reuters) - The leader of Germany's Social Democrats (SPD) took the stage at a Greens party congress on Saturday with an unashamed pitch for them to throw in their lot with the SPD to defeat Chancellor Angela Merkel in September. It was the first time an SPD leader had addressed a Greens congress. Sigmar Gabriel, whose party would need a coalition with the rising pro-environment party to have any chance of leading the next government, delivered a passionate plea to the Greens to stop flirting with Merkel's conservatives.

North Korea says detained American tourist to face trial

SEOUL (Reuters) - North Korea said on Saturday that a Korean-American tourist, jailed by the reclusive state since late last year, will face trial for "committing crimes" against the North. The move comes amid a diplomatic standoff between North Korea and the United States, and as Pyongyang has threatened to attack U.S. military bases in the Pacific and the South.

Nigerian senator says 228 killed in gunfight with Islamists

MAIDUGURI, Nigeria (Reuters) - A gunbattle between security forces and Islamist insurgents in Nigeria a week ago killed 228 people, a local senator said on Saturday, putting the death toll six times higher than the government's estimate. A large number of civilian deaths will fuel accusations that the military acted heavy-handedly and failed to protect bystanders and might also increase pressure on the government to seek a negotiated settlement with the radical group Boko Haram.

Iceland's center-right set to return, five years after crash

REYKJAVIK (Reuters) - Icelanders fed up with years of belt-tightening looked set on Saturday to oust the ruling Social Democrats, wooed with pledges of tax cuts and debt relief from the center-right, which presided over a spectacular financial collapse five years ago. Leaden skies and driving sleet were a fair reflection of the mood of voters who have seen promises of a quick recovery fade, while mortgage debts rise, prices soar and crippling capital controls keep investment at a record low.

Yemen military intelligence official assassinated

ADEN (Reuters) - Two suspected Islamist militants shot dead a provincial military intelligence chief in Yemen on Saturday, a security official said, the latest in a series of assassinations in the impoverished state's lawless south and east. The gunmen opened fire from a motorbike, killing Colonel Ahmed Abdulrazzaq, intelligence head in Yemen's Hadramawt Province, outside his home in Mukalla on the Arabian Sea.

Analysis: Israeli credibility on line over Iran nuclear challenge

By Crispian Balmer and Dan Williams

JERUSALEM (Reuters) - Israel risks a loss of credibility over both its "red line" for Iran's nuclear program and its threat of military action, and its room for unilateral maneuver is shrinking.

After years of veiled warnings that Israel might strike the Islamic Republic, Prime Minister Benjamin Netanyahu laid out an ultimatum at the United Nations last September.

Iran, he said, must not amass enough uranium at 20 percent fissile purity to fuel one bomb if enriched further. To ram the point home, he drew a red line across a cartoon bomb, guaranteeing him front page headlines around the world.

However, a respected Israeli ex-spymaster says Iran has skillfully circumvented the challenge. Other influential voices say the time has passed when Israel can hit out at Iran alone, leaving it dependent on U.S. decision-makers.

"If there was a good window of opportunity to attack, it was six months ago - not necessarily today," said Giora Eiland, a former Israeli national security adviser. Pressure from Washington, he said, had forced Israel to drop its strike plan.

Israel has long insisted on the need for a convincing military threat and setting clear lines beyond which Iran's nuclear activity should not advance, calling this the only way to persuade Iran that it must bow to international pressure.

Serving officials argue that Netanyahu's repeated warnings of the menace posed by Iran's nuclear project have pushed the issue to the top of the global agenda and helped generate some of the toughest economic sanctions ever imposed on a nation.

But some officials have also questioned the wisdom of his red line, arguing that such brinkmanship can generate unwelcome ambiguity - as the United States has discovered with its contested stance on the use of chemical weapons in Syria.

Amos Yadlin, a former military intelligence chief who runs a Tel Aviv think-tank, suggested last week that Israel had also got itself into a tangle, saying Iran had expanded its nuclear capacity beyond the Israeli limit, without triggering alarms.

"Today it can be said that the Iranians have crossed the red line set by Netanyahu at the U.N. assembly," Yadlin told a conference at the Institute for National Security Studies (INSS), which he heads.

DRUM BEAT RESUMES

Netanyahu's office declined to respond to Yadlin's remarks, noting that the prime minister, in recent public statements, had said Iran was "continuing to get closer to the red line".

Tehran denies there is any military component to its nuclear activities, saying it is focused only on civilian energy needs. It charges that Israel, widely believed to have the Middle East's only nuclear arsenal, is the greater regional threat.

Keeping in step with Netanyahu, Israeli defense and military officials issued clear warnings this month that Israel was still prepared to go it alone against Iran, once more beating the drums of war after months of relative quiet.

"We will do what is necessary when it is necessary," armed forces chief of staff Benny Gantz told Israel Radio on April 16.

But there is increasing skepticism within diplomatic circles about the viability of such an option. Envoys doubt that the Israeli military could now make much of a dent on Iran's far-flung, well-fortified nuclear installations.

"If nothing happened last year, I struggle to see why it will happen this year," said a top Western diplomat in Tel Aviv, speaking on condition of anonymity given the sensitivities.

Israeli President Shimon Peres has done little to bolster belief in unilateral action, making clear this month that he thought U.S. President Barack Obama would be the one to go to war against Iran if nuclear diplomacy failed.

"He knows no one else will do it," Peres told Israeli TV.

The United States offered Netanyahu a new array of military hardware last week, including refueling tankers that could be used to get fighter jets to and from Iranian targets.

However, Israel cannot match the sort of firepower that the United States could bring to a battlefield. For example, Israel lacks the biggest bunker-busting bombs that experts say would be needed to penetrate Iran's underground Fordow enrichment plant.

Such limitations always cast doubt on a possible Israeli assault and the more time passes, the more the doubts grow.

Ehud Barak, the previous Israeli defense minister, said in November 2011 that within nine months it would probably be impossible to halt Iran because it was increasing the number of centrifuges and its network of sites, creating what he termed a "zone of immunity". Seventeen months have gone by since then.

RECONVERSION RATES

Washington has promised Israel it will not let Iran develop a nuclear bomb. Israelis get jittery, however, because they have set a very different clock for when they believe it would be necessary to intervene - hence the importance of the red line.

The Israelis make no distinction between Iran developing the capacity to build an atomic bomb and having the actual weapon. Yadlin told the INSS conference that as soon as Tehran could put just one rudimentary device on a boat and sail it to an Israeli port, it was a de-facto nuclear-armed nation.

Some analysts question whether Iran would indeed attack Israel if it had an atom bomb, or even try to build one, rather than just establish an apparent nuclear capability to project deterrence and regional power. To fire a nuclear weapon at Israel, they say, could spell the ruin of the Islamic Republic in counter-strikes by a foe with a far bigger nuclear arsenal.

Gantz himself said last year he felt Iran's leadership was "very rational" and unlikely to build an atomic bomb.

The U.S. concern is to prevent Iran, which has called for Israel's destruction, from reaching the verge of acquiring a nuclear bomb - a nuance at variance with Israel's position that provides a longer window of opportunity to continue diplomacy.

Exasperated by Washington's refusal to set a clear ultimatum, Netanyahu came up with his 240-250 kg (530-550 pound) limit for 20 percent enriched uranium, hoping this would concentrate minds. The Iranians stayed below this threshold by converting 110 kg of the gaseous material to solid form that they say is destined to power a research reactor.

Yadlin said that rather than turn all of this into solid reactor fuel, Iran had kept 80 kg of it in the interim powdered state. That, he said, could be converted back to original gas form in around a week, inflating the stockpile beyond 250 kg.

With the red line in possible jeopardy, and unilateral military action in doubt, one security official suggested that Israel might turn to covert sabotage, with renewed focus on those specifically working on the 20 percent enrichment.

Five Iranian scientists and academics have been killed or attacked since 2010 in incidents believed to have targeted Iran's nuclear program. Israel has remained silent about the attacks and other known acts of sabotage at Iranian sites.
