Climate negotiation as a bargaining game Posted: 12 May 2014 09:43 AM PDT For more than two decades, mem­bers of the United Nations have sought to forge an agree­ment to reduce global green­house gas emis­sions. But so far, these inter­na­tional cli­mate nego­ti­a­tions have had lim­ited success. International climate negotiations have failed for 25 years. New research uses game theory to find out why, and what we can do to win the climate game.

Computer model helps Benin vaccinate more kids at lower cost Posted: 12 May 2014 09:43 AM PDT A modeling software called HERMES has been used by researchers to help the Republic of Benin in West Africa determine how to bring more lifesaving vaccines to its children. Results from the HERMES model have helped the country enact some initial changes in their vaccine delivery system, which may lead to further changes nationwide.

Ultra-fast bionic arm can catch objects on the fly Posted: 12 May 2014 07:17 AM PDT With its palm open, the robot is completely motionless. A split second later, it suddenly unwinds and catches all sorts of flying objects thrown in its direction -- a tennis racket, a ball, a bottle. This arm measures about 1.5 meters long and keeps an upright position. It has three joints and a sophisticated hand with four fingers. It is unique, as it has the ability to catch projectiles of various irregular shapes in less than five hundredths of a second.

HADES searches for dark matter: Astrophysicists cross 'Dark Photon' off the list in top position Posted: 12 May 2014 07:17 AM PDT Recent results of HADES experiments have shown, that the dark photon or U boson is no longer a top candidate to explain the nature of dark matter. Researchers are now searching for the constituents of dark matter at HADES, the High-Acceptance Di-Electron Spectrometer. These negative results -- recently published in Physics Letters B -- could even lead to challenges of the standard model of particle physics.

Artificial magnetic bacteria 'turn' food into natural drugs Posted: 12 May 2014 07:14 AM PDT Scientists have successfully created magnetic bacteria that could be added to foodstuffs and could, after ingestion, help diagnose diseases of the digestive system like stomach cancer. These important findings constitute the first use of a food as a natural drug and aid in diagnosing an illness, anywhere in the world.

A turbulent birth for stars in merging galaxies Posted: 12 May 2014 07:14 AM PDT Using state of the art computer simulations, a team of French astrophysicists have for the first time explained a long standing mystery: why surges of star formation (so called 'starbursts') take place when galaxies collide.

Mars canyons: Against the current with lava flows Posted: 12 May 2014 07:14 AM PDT An Italian astronomer in the 19th century first described them as 'canali' – on Mars' equatorial region, a conspicuous net-like system of deep gorges known as the Noctis Labyrinthus is clearly visible. The gorge system, in turn, leads into another massive canyon, the Valles Marineris, which is 4,000 km long, 200 km wide and 7 km deep. Both of these together would span the US completely from east to west.

Endocrine disruptors impair human sperm function, research finds Posted: 12 May 2014 07:14 AM PDT A plethora of endocrine-disrupting chemicals interfere with human sperm function in a way that may have a negative impact on fertilization, according to new research. The work suggests that endocrine disruptors may contribute to widespread fertility problems in the Western world in a way that hitherto has not been recognized.

New software aids breast cancer risk assessment Posted: 08 May 2014 06:54 AM PDT DMScan, a new software to aid breast cancer risk assessment, has been developed by researchers to aid in the risk assessment of breast cancer. From the images obtained in mammograms, the software objectively quantifies breast density, a value directly related to the risk of this pathology. Breast cancer is the malignant tumor with the highest incidence in women from around the world, with more than 1.6 million new cases diagnosed every year.

National coordination needed to advance convergent research, report finds Posted: 07 May 2014 08:48 AM PDT Convergent research -- which crosses disciplinary boundaries, integrating tools and knowledge from the life sciences, physical sciences, engineering, and other fields -- could spur innovation and help tackle societal challenges, but greater national coordination is needed, says a new report. Convergent science still faces hurdles and requires a culture shift for research institutions, which have traditionally organized research around separate disciplines.
