There is enough energy available in winds to meet all of the world’s demand. Atmospheric turbines that convert steadier and faster high-altitude winds into energy could generate even more power than ground- and ocean-based units. New research from Carnegie’s Ken Caldeira examines the limits of the amount of power that could be harvested from winds,…
Researchers at Newcastle University have revealed the mechanism by which neurons, the nerve cells in the brain and other parts of the body, age. The research, published in Aging Cell, opens up new avenues of understanding for conditions where the ageing of neurons are known to be responsible, such as dementia and Parkinson’s disease. The…
While traditionally we think of only double helix DNA, scientists from Cambridge University in England have made an interesting discovery. According to the researchers, a quadruple helix is also present in some cells and is believed to relate to cancer in some ways. According to the researchers, controlling these quadruple helix structures could provide new…
A new study finds that diaries and writings from ninth-century Baghdad provide insight regarding strange weather from the era, which could allow scientists to better understand the planet’s weather history. The surviving documents were written by historians and scholars during the Islamic Golden Age between A.D. 816 and A.D. 1009. They represent one of the…
Marine scientists, planners and government officials say millions of mollusks planted in waters off New York and other cities could go a long way toward cleaning up America’s polluted urban environment. The oyster and other shellfish can slurp up toxins and eliminate decades of dirt. Landscape architect Kate Orff has a name for the work…
