Christian Santangelo, Ryan Hayward and colleagues at the University of Massachusetts Amherst recently employed photographic techniques and polymer science to develop a new technique for printing two-dimensional sheets of polymers that can fold into three-dimensional shapes when water is added. The technique may lead to wide ranging practical applications from medicine to robotics The journal Science publishes the research in its March 9 issue. Researchers used a photomask and ultraviolet (UV) light to "print" a pattern onto a sheet of polymers, a technique called photolithography. ...

Researchers have identified a genetic signature for a severe, often painful food allergy – eosinophilic esophagitis – that could lead to improved diagnosis and treatment for children unable to eat a wide variety of foods. The scientists, from Cincinnati Children's Hospital Medical Center, report in the Journal of Allergy and Clinical Immunology that they have pinpointed a dysregulated microRNA signature for eosinophilic esophagitis (EoE), a disease that also may cause weight loss, vomiting, heartburn and swallowing difficulties. Interestingly, the dysregulated microRNA ...

The faster a clock ticks, the more precise it can be. Due to the fact that lightwaves vibrate faster than microwaves, optical clocks can be more precise than the caesium atomic clocks which presently determine time. The Physikalisch-Technische Bundesanstalt (PTB) is even working on several of such optical clocks simultaneously. The model with one single ytterbium ion caught in an ion trap is now experiencing another increase in accuracy. At PTB, scientists have succeeded in exciting a quantum-mechanically strongly "forbidden" transition of this ion and – in particular – ...

The detailed feather pattern and color of Microraptor--a pigeon-sized, four-winged dinosaur that lived about 120 million years ago--had a glossy iridescent sheen. Its tail was narrow and adorned with a pair of streamer feathers, suggesting the importance of display in the early evolution of feathers, say scientists reporting the findings in this week's issue of the journal Science. By comparing the patterns of pigment-containing organelles from a Microraptor fossil to those in modern birds, the scientists determined that the dinosaur's plumage was iridescent with a ...

Infants and toddlers who have been treated for cancer tend to reach certain developmental milestones later than do their healthy peers, say researchers at the National Institutes of Health and in Italy. The findings show that delays may occur early in the course of treatment and suggest that young children with cancer might benefit from such early interventions as physical or language therapy. Compared to children who had not had cancer, children treated for cancer before age 4 progressed more slowly in vocabulary, cognitive functions such as attention and memory, and ...

Amsterdam, NL, 9 March 2012 – The number of people with neurological and psychiatric disorders in Spanish-speaking countries has increased over the past two decades. The February issue of NeuroRehabilitation assesses important factors that should be considered in rehabilitating Spanish-speaking individuals suffering from these disorders. "Though much work has been done in this area for Anglo-Saxon populations, very little work has focused on Spanish-speaking individuals," says Guest Editor Juan Carlos Arango-Lasprilla, PhD, of the Department of Physical Medicine and ...

How do we recognize a face? To date, most research has answered "holistically": We look at all the features—eyes, nose, mouth—simultaneously and, perceiving the relationships among them, gain an advantage over taking in each feature individually. Now a new study overturns this theory. The researchers—Jason M. Gold and Patrick J. Mundy of the Indiana University and Bosco S. Tjan of the University of California Los Angeles—found that people's performance in recognizing a whole face is no better than their performance with each individual feature shown alone. "Surprisingly, ...

An international team of physicists has determined a key parameter, which governs how neutrinos behave. This discovery measures a critical linchpin in the study of the tiny particles and in advancing the understanding of how these building blocks of all things, from galaxies to tea cups, came to be. The Daya Bay Reactor Neutrino Experiment, a multinational collaboration including a team from Virginia Tech, discovered a new type of neutrino oscillation in which the particles appear to vanish as they travel. The researchers found that the rate of oscillations was much larger ...

A neutron star is the closest thing to a black hole that astronomers can observe directly, crushing half a million times more mass than Earth into a sphere no larger than a city. In October 2010, a neutron star near the center of our galaxy erupted with hundreds of X-ray bursts that were powered by a barrage of thermonuclear explosions on the star's surface. NASA's Rossi X-ray Timing Explorer (RXTE) captured the month-long fusillade in extreme detail. Using this data, an international team of astronomers has been able to bridge a long-standing gap between theory and observation. "In ...

Cyclone Irina has lived a long life and caused a lot of trouble, damages and death over the course of its life, and it appears to be finally fading over the Mozambique Channel. On March 8 at 1500 UTC (10 a.m. EST), Irina's winds had finally dropped below 45 knots (51.7 mph/83.3 kph) to 35 knots (40.2 mph/64.8 kph) making it a minimal tropical storm. Irina was still in the southern Mozambique Channel, centered near 29.5 South and 37.8 East. That is about 350 miles southeast of Maputo, Mozambique. Irina is moving to the west at 8 knots (9.2 mph/14.8 kph). The Moderate ...

Hot towers, or towering thunderclouds that give off an excessive amount of latent heat, usually indicate a tropical cyclone will strengthen in six hours, and NASA's TRMM satellite saw some of them as it passed by Tropical Storm Koji. The Tropical Rainfall Measuring Mission (TRMM) satellite passed directly above an intensifying tropical storm in the South Indian Ocean called Koji on March 8, 2012 at 2053 UTC (3:53 p.m. EST). A rainfall analysis was made from TRMM Microwave Imager (TMI) and Precipitation Radar (PR) data. Those TRMM data reveal that Koji was getting organized ...

DURHAM, N.C. – A team of researchers at Duke University has determined the structure of a key molecule that can carry chemotherapy and anti-viral drugs into cells, which could help to create more effective drugs with fewer effects to healthy tissue. "Knowing the structure and properties of the transporter molecule may be the key to changing the way that some chemotherapies, for example, could work in the body to prevent tumor growth," said senior author Seok-Yong Lee, Ph.D., assistant professor of biochemistry at Duke. The article was published in Nature online on ...

A team of Australian scientists has bred salt tolerance into a variety of durum wheat that shows improved grain yield by 25% on salty soils. Using 'non-GM' crop breeding techniques, scientists from CSIRO Plant Industry have introduced a salt-tolerant gene into a commercial durum wheat, with spectacular results shown in field tests. Researchers at the University of Adelaide's Waite Research Institute have led the effort to understand how the gene delivers salinity tolerance to the plants. The research is the first of its kind in the world to fully describe the improvement ...

The Greenland ice sheet is likely to be more vulnerable to global warming than previously thought. The temperature threshold for melting the ice sheet completely is in the range of 0.8 to 3.2 degrees Celsius global warming, with a best estimate of 1.6 degrees above pre-industrial levels, shows a new study by scientists from the Potsdam Institute for Climate Impact Research (PIK) and the Universidad Complutense de Madrid. Today, already 0.8 degrees global warming has been observed. Substantial melting of land ice could contribute to long-term sea-level rise of several meters ...

In a study released today in Nature Genetics, researchers have found that Chlamydia has evolved more actively than was previously thought. Using whole genome sequencing the researchers show that the exchange of DNA between different strains of Chlamydia to form new strains is much more common than expected. The team highlights that current clinical testing methods do not capture the variation between Chlamydia strains. Changes to the genome structure are not the aim of current diagnostics for Chlamydia. The researchers are working with hospitals to use their results ...

Hospitals in Arizona and across the country are burying their mistakes, according to a new study recently released by U.S. Department of Health and Human Services Inspector General Daniel R.

NEW YORK, NY -- A study by Columbia researchers suggests that cells in the patient's intestine could be coaxed into making insulin, circumventing the need for a stem cell transplant. Until now, stem cell transplants have been seen by many researchers as the ideal way to replace cells lost in type I diabetes and to free patients from insulin injections. The research—conducted in mice—was published 11 March 2012 in the journal Nature Genetics. Type I diabetes is an autoimmune disease that destroys insulin-producing cells in the pancreas. The pancreas cannot replace these ...
