Next-generation steel and metal alloys are a step closer to reality, thanks to an international research project. The work could overcome the problem of hydrogen alloy embrittlement that has led to catastrophic failures in major engineering and building projects.
A little empathy can go a long way toward ending infectious disease outbreaks. That's a conclusion from researchers who used a networked variation of game theory to study how individual behavior during an outbreak of influenza -- or other illness -- affects the progress of the disease, including how rapidly the outbreak dies out.
Nano satellites weighing just a few kilograms orbit the Earth. Pivotal point of these miniature computers are their solar-powered batteries. Computer scientists have now developed a procedure that allows for better planning of solar battery operations.
A new project aims to create an efficient, simple-to-manufacture oxygen-evolution catalyst that pairs well with semiconductors for advanced solar cells. The technique could lead to unique catalysts for other applications.
New research examining the impact multiple forms of evidence has on juror perceptions during criminal trials has found the use of video material could be detrimental without the use of a judicial warning.
Concentrated poverty -- neighborhoods where 40 percent of the population or more lives below the federal poverty level -- is back on the rise for all ethnic groups in the United States, according to demographers.
On the eve of this year's Earth hour (March 25), researchers propose a solution in the journal Science for the global economy to rapidly reduce carbon emissions. The authors argue a carbon roadmap, driven by a simple rule of thumb or 'carbon law' of halving emissions every decade, could catalyze disruptive innovation.
Marine protected areas (MPAs) are an increasingly popular strategy for protecting marine biodiversity, but a new global study demonstrates that widespread lack of personnel and funds are preventing MPAs from reaching their full potential. Only 9 percent of MPAs reported having adequate staff.
Despite worldwide progress since the WHO Framework Convention on Tobacco Control (WHO-FCTC) came into effect in 2005, not all key demand-reduction measures have been fully implemented at the same pace, but doing so could reduce tobacco use even further, say researchers.
One popular theory holds that dominant leaders are supported by those who fear new situations and threats. However, new research shows that support for dominant leaders is not born of fear, but of a wish to handle the country's problems by aggressive means.
Tasty, versatile, and rich in essential omega-3 fatty acids: salmon is one of the most popular edible fish of all. Shops sell fish caught in the wild, but their main produce is salmon from breeding farms which can pollute rivers, lakes and oceans. Just how big is the problem? Scientists are working to answer this question by examining the dissolved organic compounds which enter Chile’s rivers from salmon farms. They warn that these substances are placing huge strain on ecosystems and are changing entire biological communities.
Long gone are the days when a life of material excess and endless leisure time signified prestige. According to a new study, Americans increasingly perceive busy and overworked people as having high status.
