Synthesized 'solar' jet fuel: Renewable kerosene from sunlight, water and carbon dioxide

Posted: 03 May 2014 03:49 PM PDT

With the first ever production of synthesized "solar" jet fuel, the EU-funded SOLAR-JET project has successfully demonstrated the entire production chain for renewable kerosene obtained directly from sunlight, water and carbon dioxide, therein potentially revolutionizing the future of aviation. This process has also the potential to produce any other type of fuel for transport applications, such as diesel, gasoline or pure hydrogen in a more sustainable way.

A cup of coffee a day may keep retinal damage away, study shows

Coffee drinkers, rejoice! Aside from java's energy jolt, food scientists say you may reap another health benefit from a daily cup of joe: prevention of deteriorating eyesight and possible blindness from retinal degeneration due to glaucoma, aging and diabetes.

Reducing just six risk factors could prevent 37 million deaths from chronic diseases over 15 years

Posted: 02 May 2014 05:47 PM PDT

Reducing or curbing just six modifiable risk factors -- tobacco use, harmful alcohol use, salt intake, high blood pressure and blood sugar, and obesity -- to globally-agreed target levels could prevent more than 37 million premature deaths over 15 years, from the four main non-communicable diseases (NCDs): cardiovascular diseases, chronic respiratory disease, cancers, and diabetes, according to new research.

Key protein enhances memory, learning

Posted: 02 May 2014 10:24 AM PDT

A protein previously implicated in disease plays such a positive role in learning and memory that it may someday contribute to cures of cognitive impairments, researchers have discovered. The findings regarding the potential virtues of fatty acid binding protein 5 -- usually associated with cancer and psoriasis -- have been outlined in a new article.

Undersea warfare: Viruses hijack deep-sea bacteria at hydrothermal vents

Posted: 01 May 2014 12:10 PM PDT

More than a mile beneath the ocean's surface, as dark clouds of mineral-rich water billow from seafloor hot springs called hydrothermal vents, unseen armies of viruses and bacteria wage war.

Whales hear us more than we realize: Sonar signal 'leaks' likely audible to some marine mammals

Posted: 01 May 2014 12:09 PM PDT

Killer whales and other marine mammals likely hear sonar signals more than we've known. That's because commercially available sonar systems, which are designed to create signals beyond the range of hearing of such animals, also emit signals known to be within their hearing range, scientists have discovered.

Climate change study reveals unappreciated impacts on biodiversity

Posted: 01 May 2014 11:22 AM PDT

The tropics ill be highly affected by local changes in temperature and precipitation, leading to novel climates with no current analogues in the planet. These results expose the complexities of climate change effects on biodiversity and the challenges in predicting and preserving natural ecosystems in a changing Earth.

Regenerative medicine approach improves muscle strength, function in leg injuries; Derived from pig bladder

Posted: 30 Apr 2014 11:30 AM PDT

Damaged leg muscles grew stronger and showed signs of regeneration in three out of five men whose old injuries were surgically implanted with extracellular matrix derived from pig bladder, according to a new study. Early findings are from a human trial of the process as well as from animal studies.
