Immunosignaturing: An accurate, affordable and stable diagnostic

Identifying diseases at an early, presymptomatic stage may offer the best chance for establishing proper treatment and improving patient outcomes. A new technique known as immunosignaturing harnesses the human immune system as an early warning sentry—one acutely sensitive to changes in the body that may be harbingers of illness.

First fruitful, then futile: Ammonites or the boon and bane of many offspring

For 300 million years, they were the ultimate survivors. They successfully negotiated three mass extinctions, only to die out eventually at the end of the Cretaceous along with the dinosaurs: Ammonoids, or ammonites as they are also known, were marine cephalopods believed to be related to today's squid and nautiloids. Ammonoids changed their reproductive strategy early on in the course of evolution.

Compressed sensing allows super-resolution microscopy imaging of live cell structures

Researchers from the Georgia Institute of Technology and University of California San Francisco have advanced scientists' ability to view a clear picture of a single cellular structure in motion. By identifying molecules using compressed sensing, this new method provides needed spatial resolution plus a faster temporal resolution than previously possible.

Despite many achievements in the field of super-resolution microscopy in the past few years with spatial resolution advances, live-cell imaging has remained a challenge because of the need for high temporal resolution.

Keeping older drivers on the road

A research car which monitors our concentration, stress levels and driving habits while we're sat behind the steering wheel is being used to develop new technologies to support older drivers.

The Intelligent Transport team at Newcastle University, UK, have converted an electric car into a mobile laboratory.

Dubbed 'DriveLAB', the car is kitted out with tracking systems, eye trackers and bio-monitors in an effort to understand the challenges faced by older drivers and to identify where the key stress points are.

Avocado oil: The 'olive oil of the Americas'?

SAN DIEGO, April 22, 2012 – Atmospheric oxygen facilitated the evolution and complexity of terrestrial organisms, including human beings, because it allowed nutrients to be used more efficiently by those organisms, which in turn were able to generate more energy. However, as we find out more about how oxygen molecules work inside the body, more attention is being paid to their not-so-good effects, and researchers are seeking ways to thwart them.

Army researcher develops potential vaccine carrier

A researcher at the Brooke Army Medical Center (BAMC)/San Antonio Military Medical Center (SAMMC) will present findings this week on a new potential vaccine carrier that he hopes will extend the shelf life of and aid in the stockpiling of critical vaccines.

Potato consumption lower than expected

SAN DIEGO - Calorie intake from white potatoes is surprisingly modest for adults and school-aged children, according to a new study released today at the Experimental Biology 2012 Annual Meeting.

Dr. Maureen Storey, Chief Executive Officer for the science-based Alliance for Potato Research and Education (APRE) presented the new analysis using data from the Centers for Disease Control and Prevention's National Health and Nutrition Examination Survey (NHANES).

NCEAS researchers offer new ecological model for deep-water oil spills

(Santa Barbara, Calif.) — On the second anniversary of the Deepwater Horizon oil platform blowout, a national panel of researchers is providing new insight into what happened in the disaster, as well as a guide for how to deal with such events in the future, and why existing tools were inadequate to predict what lay before them.

Marine scientists urge government to reassess oil spill response

Athens, Ga. – On the second anniversary of the Deepwater Horizon blowout, a national panel of researchers including University of Georgia marine scientist Samantha Joye is urging the federal government to reassess how it would respond to similar oil spills that might occur in the future.

Save big on heating, cooling costs with efficiency controls

RICHLAND, Wash. – U.S. commercial building owners could save an average of 38 percent on their heating and cooling bills if they installed a handful of energy efficiency controls that make their heating, ventilation and air conditioning, also known as HVAC, systems more energy efficient, according to a recent report from the Department of Energy's Pacific Northwest National Laboratory. The estimated savings were based on computer modeling and simulation of building energy usage.

Study: Optimizing biofuel supply chain is a competitive game

CHAMPAIGN, Ill. — As biofuel production has increased – particularly ethanol derived from corn – a hotly contested competition for feedstock supplies has emerged between the agricultural grain markets and biofuel refineries. This competition has sparked concern for the more fundamental issue of allocating limited farmland resources, which has far-reaching implications for food security, energy security and environmental sustainability.

Anti-tobacco TV ads help adults stop smoking, study finds

Anti-tobacco television advertising helps reduce adult smoking, according to a study by researchers at the University of Illinois at Chicago's Institute for Health Research and Policy -- but some ads may be more effective than others.

Adults and youth are exposed to a variety of anti-smoking messages on television. However, no research had been done on whether the ads, produced by various sponsors, impact adult smoking behaviors, or on how the ads differ, says Sherry Emery, a senior scientist at the UIC institute and lead author of the study.

ORNL microscopy yields first proof of ferroelectricity in simplest amino acid

OAK RIDGE, Tenn., April 19, 2012 —The boundary between electronics and biology is blurring with the first detection by researchers at Department of Energy's Oak Ridge National Laboratory of ferroelectric properties in an amino acid called glycine.

A multi-institutional research team led by Andrei Kholkin of the University of Aveiro, Portugal, used a combination of experiments and modeling to identify and explain the presence of ferroelectricity, a property where materials switch their polarization when an electric field is applied, in the simplest known amino acid—glycine.

The solar cell that also shines: Luminescent 'LED-type' design breaks efficiency record

WASHINGTON, April 19—To produce the maximum amount of energy, solar cells are designed to absorb as much light from the Sun as possible. Now researchers from the University of California, Berkeley, have suggested – and demonstrated – a counterintuitive concept: solar cells should be designed to be more like LEDs, able to emit light as well as absorb it. The Berkeley team will present its findings at the Conference on Lasers and Electro Optics (CLEO: 2012), to be held May 6-11 in San Jose, Calif.

Scientists find higher concentrations of heavy metals in post-oil spill oysters from Gulf of Mexico

As the two-year anniversary of the Deepwater Horizon oil spill in the Gulf of Mexico approaches, a team of scientists led by Dr. Peter Roopnarine of the California Academy of Sciences has detected evidence that pollutants from the oil have entered the ecosystem's food chain. For the past two years, the team has been studying oysters (Crassostrea virginica) collected both before and after the Deepwater Horizon oil reached the coasts of Louisiana, Alabama, and Florida.
