Ocean bacteria get 'pumped up' by dying phytoplankton

The ocean has been sucking up heat-trapping carbon dioxide (CO2) building up in our atmosphere--with a little help from tiny plankton. Like plants on land, these plankton convert CO2 into organic carbon via photosynthesis. But unlike land plants that are held fast to terra firma, plankton can sink into the deep ocean, carrying carbon with them. Show More Summary

The monk parakeet: Tracking an invasive bird

The monk parakeets that have invaded Europe and North America over the last 40-50 years fortifying their massive communal nests atop utility poles in many urban areas appear to have originated from the same small area in South America, according to a new study.

Alternate theory of inhabitation of North America disproven

The most widely accepted theory of the inhabitation of North America is that humans migrated from Siberia to Alaska by means of a 'land bridge' that spanned the Bering Strait. However, in the 1990s, a small group of researchers proposed...Show More Summary

Breakthrough in understanding Canavan disease

Investigators have settled a long-standing controversy surrounding the molecular basis of an inherited disorder that historically affected Ashkenazi Jews from Eastern Europe but now also arises in other populations of Semitic descent, particularly families from Saudi Arabia. Show More Summary

No health drawbacks to veterans' dual use of VA, Medicare Advantage, study says

In a study that looked at a handful of quality measures for chronic disease care, veterans who used both Veterans Affairs care and a Medicare Advantage plan during 2008 or 2009 did no better or worse than those who relied strictly on VA.

Health insurance coverage among cancer patients varies greatly by demographics and cancer type

Among patients with cancer, rates of health insurance coverage vary by patient demographics and by cancer type, a new analysis has found. The researchers found that younger, non-white, unmarried patients residing in counties with higher levels of poverty and in rural areas were less likely to have insurance. Show More Summary

Church Where Pocahontas Married Rises Again

A group of archaeologists in Jamestown, Virginia, is busy doing the opposite of what one would normally expect: building something new, rather than searching for what once was. Popular Archaeology reports that an effort is underway to rebuild a potion of the church where Pocahontas wed John Rolfe in 1614...

Two thirds of the world's population have no access to safe, affordable surgery

Millions of people are dying from common, easily treatable conditions like appendicitis, fractures, or obstructed labor because they do not have access to, or can't afford, proper surgical care, according to a major new report. The new...Show More Summary

Audi samples diesel made directly from carbon dioxide

High-temperature process just needs steam and any source of CO 2.

Strange supernova is 'missing link' in gamma-ray burst connection

Astronomers find that 'central engines' in supernova explosions can come in different strengths, and include those that produce powerful blasts of gamma rays, and weaker versions that produce no such bursts.

How an RNA gene silences a whole chromosome

Researchers have discovered how an abundant class of RNA genes, called lncRNAs can regulate key genes. By studying an important lncRNA, called Xist, the scientists identified how this RNA gathers a group of proteins and ultimately prevents...Show More Summary

Brain balances perception and action when caught in an illusion

Two wrongs can make a right, at least in the world of visual perception and motor functioning, according to brain scientists who tracked the eyes of students during exercises in a dark laboratory.

Astrophysicists draw most comprehensive map of the universe

Astrophysicists have created a 3-D map of the universe that spans nearly two billion light years and is the most complete picture of our cosmic neighborhood to date.

A new future for corals: Persistence and change in coral reef communities

Coral reefs, true reservoirs of biodiversity, are seriously threatened by human activities and climate change. Consequently, their extinction has often been heralded. Now, researchers are painting a less gloomy picture: the planet’s reefs are not doomed to disappear. Show More Summary

Hate to diet? It's how we're wired

If you're finding it difficult to stick to a weight-loss diet, scientists say you can likely blame AGRP neurons -- hunger-sensitive cells in your brain. New experiments show these neurons are responsible for the unpleasant feelings of hunger that make snacking irresistible. Show More Summary

Parallel sequencing of DNA and RNA provides insight into secret world of cells

Researchers have developed a large-scale sequencing technique called Genome and Transcriptome Sequencing (G&T-seq) that reveals, simultaneously, the unique genome sequence of a single cell and the activity of genes within that single cell.

Electrical power converter allows grid to easily accept power from renewable energy

Engineering researchers have invented a novel electrical power converter system that simultaneously accepts power from a variety of energy sources and converts it for use in the electrical grid system.

Brits reluctant to share personal data to enable 'smart' energy use

Reluctance to share data about personal energy use is likely to be a major obstacle when implementing 'smart' technologies designed to monitor use and support energy efficient behaviors, according to new research led by academics atShow More Summary
