The new breed of cutting-edge catalysts

 Advances in catalyst research could create a superhighway to clean energy sources and a more-sustainable chemical industry. “Chemists are striving to build catalysts around cheaper, 'Earth-abundant' elements such as iron, nickel or copper.” In her 1794 book, An Essay on Combustion, Scottish chemist Elizabeth...

US researchers build CNT FETS with current density of 900mA mm-1

University of Wisconsin-Madison materials engineers have created semiconducting single-walled carbon nano tubes (CNTs) that outperform state-of-the-art silicon and GaAs transistors. The researchers reported their advance in Science Advances in a paper titled 'Quasi-ballistic carbon nano tube array...

Where you live shapes your immune system more than your genes

Like fingerprints, immune systems vary from person to person. And although we all inherit a unique set of genes that help us respond to infections, recent studies have found that our history and environment--like where and with whom we live--are responsible for 60% to 80% of the differences between individual immune systems,...

Benefits And Danger's of Honey

Honey has been valued as a natural sweetener long before sugar became widely available in the 16th century. Honey production flourished in ancient Greece and Sicily, for instance, while animals other than humans – bears, badgers, and more – have long raided honeybee hives, risking stings for the sweet reward. Honey...

Ear ossicles of modern humans and Neanderthals: Different shape, similar function

Scientists have scanned the skulls of Neanderthals and found the small middle ear ossicles, which are important for hearing, still preserved within the cavities of the ear. To their surprise, the Neanderthal ossicles are morphologically distinct from the ossicles of modern humans. Despite the differences in morphology,...

Automated screening for childhood communication disorders

For children with speech and language disorders, early-childhood intervention can make a great difference in their later academic and social success. But many such children -- one study estimates 60 percent -- go diagnosed until kindergarten or even later. Researchers at the Computer Science and Artificial Intelligence...

Baby's genes influence birth weight and later life disease

Genetic differences have been found that help to explain why some babies are born bigger or smaller than others. It also reveals how genetic differences provide an important link between an individual's early growth and their chances of developing conditions such as type 2 diabetes or heart disease in later life. The...
