University of Colorado Boulder scientists have found a creative way to radically improve thermoelectric materials, a finding that could one day lead to the development of improved solar panels, more energy-efficient cooling equipment, and even the creation of new devices that could turn the vast amounts of heat wasted at power...

Chronic illness, already a major and expensive problem in developed countries, is rapidly increasing in developing countries, adding to the longstanding burden caused by high rates of infectious diseases. However, poor countries will not be able to afford the costly medical technologies that wealthy countries use to treat...

Extreme weather caused by climate change in the coming decades is likely to have profound implications for distributions of insects and other invertebrates. This is suggested by a new study of insects in tropical and temperate regions of Australia. Fuente : http://www.eurekalert.org/pub_releases/2014-02/au-...

A Western University primatologist has teamed with 18 lemur conservationists and researchers, many of whom are from Madagascar or have been working there for decades, to devise an action plan to save Madagascar's 101 lemur species. The action plan contains strategies for 30 different priority sites for lemur conservation and...

Chronic stress that produces inflammation and anxiety in mice appears to prime their immune systems for a prolonged fight, causing the animals to have an excessive reaction to a single acute stressor weeks later, new research suggests. Fuente : http://www.eurekalert.org/pub_releases/2014-02/osu...

Researchers recently discovered that a common space weather phenomenon on the outskirts of Earth's magnetic bubble, the magnetosphere, has much larger repercussions for Venus. The giant explosions, called hot flow anomalies, can be so large at Venus that they're bigger than the entire planet and they can happen multiple times a...

The synthetic chemicals used in the packaging, storage, and processing of foodstuffs might be harmful to human health over the long term, warn environmental scientists. This is because most of these substances are not inert and can leach into the foods we eat, they say. Despite the fact that some of these chemicals are...

There has been some debate about whether wind turbines have a more limited shelf-life than other energy technologies. A previous study used a statistical model to estimate that electricity output from wind turbines declines by a third after only ten years of operation. Some opponents of wind power have argued that aging turbine...

Despite unprecedented investment in malaria control in Africa over the past decade, about 57% of the population still live in areas where risk of infection remains moderate to high, according to new research. However, new findings also show that substantial reductions in malaria transmission have been achieved across most of...

Cuando venza el plazo para los Objetivos de Desarrollo de la ONU para el Milenio (ODM) en 2015, habrá una omisión grave: millones de personas seguirán sin agua potable, saneamiento y electricidad en sus hogares. Conscientes de esta falta, los 193 miembros de la Asamblea General de la ONU...

New software greatly expands the types of multi-scale QM/MM (mixed quantum and molecular mechanical) simulations of complex chemical systems that scientists can use to design new drugs, better chemicals, or improved enzymes for biofuels production.

Although the time and cost of sequencing the human genome has plummeted, analyzing the 3 billion base pairs of genetic information can take months. Researchers working with Beagle —- one of the world’s fastest supercomputers devoted to life sciences —- report they can analyze 240 full genomes in 50 hours. Fuente :...

In a messy house, people use computers to manage paper and photo clutter; companies use computer systems to track their inventory. Researchers are taking a similar approach to cell-molecular inventory control for cancer. They have created computer models, using their programming framework (PySB), which enable them to explore...

The brains of jazz musicians engrossed in spontaneous, improvisational musical conversation showed robust activation of brain areas traditionally associated with spoken language and syntax, which are used to interpret the structure of phrases and sentences. But this musical conversation shut down brain areas linked to semantics...

The development of a tool that will help government officials, policy makers and healthcare providers across Europe examine the cost effectiveness and impact of anti-smoking initiatives is set to become the subject of a major new study.
