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,...

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....

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...

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...

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,...

Study finds that employees who are open about religion are happier

It may be beneficial for employers to not only encourage office Christmas parties but also celebrate holidays and festivals from a variety of religions, according to a Kansas State University...

Global carbon dioxide emissions increase to new all-time record, but growth is slowing down

2013 saw global CO2 emissions from fossil fuel use and cement production reach a new all-time high. This was mainly due to the continuing steady increase in energy use in...

Spider's web weaves way to advanced networks and displays

Refined by natural selection, spider webs and leaves serve as models for new and highly effective optoelectronic networks and displays, a team of researchers reported recently in <i>Nature Communications</i>.The next generation of light-manipulating networks may take their lead from designs inspired by spiders and leaves, according to a new report from two Boston College physicists and colleagues at...

New class of synthetic molecules mimics antibodies

SyAMs recognize disease cells and bind with a specific protein on their surface. They also bind with a receptor on an immune cell.A Yale University lab has crafted the first synthetic molecules that have both the targeting and response functions of antibodies.

Colorado River Delta greener after engineered pulse of water

Water being released from Morelos Dam in the first environmental release of water to the Colorado River Delta. The Minute 319 pulse flow of water started March 23, 2014 and ended May 18, 2014.The engineered spring flood that brought water to previously dry reaches of the lower Colorado River and its delta resulted in greener vegetation, the germination of new vegetation along the...

Australia's coastal observation network may aid in understanding of extreme ocean events

A network of nine reference sites off the Australian coast is providing the latest physical, chemical, and biological information to help scientists better understand Australia's coastal seas, according to a...

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.

Big data may be fashion industry's next must-have accessory

Big data may be the next new thing to hit the fashion industry's runways, according to a team of researchers.

'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...

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

Energy-rich waters discharge kilometers below the surface in a South African mine.A team of scientists, led by the University of Toronto's Barbara Sherwood Lollar, has mapped the location of hydrogen-rich waters found trapped kilometres beneath Earth's surface in rock fractures in...

NASA satellites measure increase of Sun's energy absorbed in the Arctic

NASA satellite instruments have observed a marked increase in solar radiation absorbed in the Arctic since the year 2000 -- a trend that aligns with the steady decrease in Arctic...

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.

Ultrafast imaging of complex systems in 3-D at near atomic resolution nears

It is becoming possible to image complex systems in 3-D with near-atomic resolution on ultrafast timescales using extremely intense X-ray free-electron laser (XFEL) pulses.

Consumer loyalty driven by aesthetics over functionality

When designing a new car, manufacturers might try to attract consumers with more horsepower, increased fuel efficiency or a lower price point. But new research from San Francisco State University...

Policy action urgently needed to protect Hawaii's dolphins

The best way to protect wild spinner dolphins in Hawaii while also maintaining the local tourism industry that depends on them is through a combination of federal regulations and community-based...

Short-necked Triassic marine reptile discovered in China

This is the holotype of <i>Eohupehsuchus brevicollis</i>, WGSC V26003.A new species of short-necked marine reptile from the Triassic period has been discovered in China, according to a study published December 17, 2014 in the open-access journal PLOS ONE...

Contrasting views of kin selection assessed

In an article to be published in the January issue of BioScience, two philosophers tackle one of the most divisive arguments in modern biology: the value of the theory of...
