NASA Goddard instrument makes first detection of organic matter on Mars

The team responsible for the Sample Analysis at Mars (SAM) instrument suite on NASA's Curiosity rover has made the first definitive detection of organic molecules at Mars. Organic molecules are the building blocks of all known forms of terrestrial life,...

Kids' cartoon characters twice as likely to die as counterparts in films for adults

The findings prompt the authors to describe children's cartoons as "rife with death and destruction," with content akin to the "rampant horrors" of popular films for adults given restrictive age...

Carbon-trapping 'sponges' can cut greenhouse gases

In the fight against global warming, carbon capture -- chemically trapping carbon dioxide before it releases into the atmosphere -- is gaining momentum, but standard methods are plagued by toxicity,...

NOAA/NASA satellite sees holiday lights brighten cities

City lights shine brighter during the holidays in the US when compared with the rest of the year, as shown using a new analysis of daily data from the NASA-NOAA Suomi NPP satellite. Dark green pixels are areas where lights are 50 percent brighter, or more, during December.Even from space, holidays shine bright.

Migrating 'supraglacial' lakes could trigger future Greenland ice loss

Supraglacial lakes on the Greenland ice sheet can be seen as dark blue specks in the center and to the right of this satellite image.Predictions of Greenland ice loss and its impact on rising sea levels may have been greatly underestimated, according to scientists at the University of Leeds.

Climate change could leave cities more in the dark

This is a list of the Atlantic and Gulf coastal region cities whose power grids are most vulnerable to increased hurricane damage because of climate change.Cities like Miami are all too familiar with hurricane-related power outages. But a Johns Hopkins University analysis finds climate change will give other major metro areas a lot to worry...

Three San Antonio studies target androgen in breast cancer

Three studies presented by University of Colorado Cancer Center researchers at the San Antonio Breast Cancer Symposium 2014 demonstrate the effects of blocking androgen receptors in breast cancer. One shows...

Life expectancy increases globally as death toll falls from major diseases

People are living much longer worldwide than they were two decades ago, as death rates from infectious diseases and cardiovascular disease have fallen, according to a new, first-ever journal publication...

'Perfect storm' quenching star formation around a supermassive black hole

This is an artist impression of the central region of NGC 1266. The jets from the central black hole are creating turbulence in the surrounding molecular gas, suppressing star formation in an otherwise ideal environment to form new stars.High-energy jets powered by supermassive black holes can blast away a galaxy's star-forming fuel, resulting in so-called "red and dead" galaxies: those brimming with ancient red stars yet containing little...

Scientists open new frontier of vast chemical 'space'

Scripps Research Institute chemists have invented a practical new method for building complex molecules that uses simple, non-toxic iron-based catalysts and can be conducted in minutes open to the air even in a shot glass of alcoholic spirits. The team includes (left to right) Jinghan Gui, Chung-Mao (Eddie) Pan, Phil Baran, Yuki Yabe and Julian Lo; here, Gui and Lo are holding molecular models, and Baran holds the actual iron catalysts.Chemists at The Scripps Research Institute (TSRI) have invented a powerful method for joining complex organic molecules that is extraordinarily robust and can be used to make pharmaceuticals, fabrics, dyes,...

Guelph researchers recipe: Cook farm waste into energy

It takes some cooking, but turning farm waste into biofuels is now possible and makes economic sense, according to preliminary research from the University of Guelph.

Wills is the Interim Director of the Cancer Prevention and Control Program at the University of Hawaii Cancer Center.

Swarms of Pluto-size objects kick-up dust around adolescent Sun-like star

This is an ALMA image of the dust surrounding the star HD 107146. Dust in the outer reaches of the disk is thicker than in the inner regions, suggesting that a swarm of Pluto-size planetesimals is causing smaller objects to smash together. The dark ring-like structure in the middle portion of the disk may be evidence of a gap where a planet is sweeping its orbit clear of dust.Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) may have detected the dusty hallmarks of an entire family of Pluto-size objects swarming around an adolescent version of our own Sun.

Penn research outlines basic rules for construction with a type of origami

Try it yourself: With a cut and a few folds, this structure could serve as a shelter or a microfluidic channel. Because the researchers' rules keep the hexagons in proportion once the cuts and folds are made, the technique can be applied broadly across length scales and material types.Origami is capable of turning a simple sheet of paper into a pretty paper crane, but the principles behind the paper-folding art can also be applied to making a microfluidic...

Surprising theorists, stars within middle-aged clusters are of similar age

A close look at the night sky reveals that stars don't like to be alone; instead, they congregate in clusters, in some cases containing as many as several million stars....

Reshaping the horse through millennia

A man catches a domestic Mongolian horse with a lasso in Khomiin Tal, Mongolia.Whole genome sequencing of modern and ancient horses unveils the genes that have been selected by humans in the process of domestication through the latest 5.500 years, but also reveals...

Massive study provides first detailed look at how Greenland's ice is vanishing

The surface of the Greenland Ice Sheet. A new study uses NASA data to provide the first detailed reconstruction of how the ice sheet and its many glaciers are changing. The research was led by University at Buffalo geologist Beata Csatho.The Greenland Ice Sheet is the second-largest body of ice on Earth. It covers an area about five times the size of New York State and Kansas combined, and if...

Past global warming similar to today's

Sediment cores that were drilled from Wyoming's Bighorn Basin and then sectioned for study are shown at a repository at the University of Bremen, Germany. A study of the cores led by University of Utah geochemist Gabe Bowen found that carbon emissions to the atmosphere during a global warming period almost 56 million years ago were more similar to today's human-caused climate change than previously was believed.The rate at which carbon emissions warmed Earth's climate almost 56 million years ago resembles modern, human-caused global warming much more than previously believed, but involved two pulses of carbon...

Switching to spintronics

This is a conceptual illustration of how magnetism is reversed (see compass) by the application of an electric field (blue dots) applied across gold capacitors. Blurring of compass needle under electric field represents two-step process.In a development that holds promise for future magnetic memory and logic devices, researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) and Cornell University...

Ancient, hydrogen-rich waters discovered deep underground at locations around the world
