Materials scientist Nobuhiko Kobayashi wasn't quite sure why the astronomer he met at a wine-tasting several years ago was so interested in his research, but as he learned more about telescope mirrors it began to make sense.

"It turns out that improving the performance of mirrors is all about thin-film materials, and that's what I do. So then I got hooked," said Kobayashi, a professor of electrical engineering in the Baskin School of Engineering at UC Santa Cruz.

HOUSTON-(Sept. 18, 2017) - Researchers at Houston Methodist have solved a 100-year-old mystery, providing them a possible key to unlock a pathway for treating diseases caused by flesh-eating bacteria. This is timely news, given the current dangers lurking in the debris and destruction left behind by Hurricane Harvey's floodwaters that destroyed tens of thousands of homes in Texas.

(Chapel Hill, N.C. -- Sept. 18, 2017) -- A new study from the University of North Carolina at Chapel Hill finds beta blockers are not needed after a heart attack if heart-attack survivors are taking ACE inhibitors and statins. The study is the first to challenge the current clinical guideline that heart-attack survivors should take all three drugs - beta blockers, ACE inhibitors and statins - for the rest of their lives.

Geriatrics experts know that certain medications may have risks for older adults that outweigh their benefits, especially when safer alternatives are available. Medications that could be "potentially inappropriate" for older adults are included on recommendation lists that your healthcare provider can consult, such as the American Geriatrics Society (AGS) Beers Criteria or the STOPP-START list.

WASHINGTON D.C., September 18, 2017 -- Today, electrical bistable devices are the foundation of digital electronics, serving as building blocks of switches, logic gates and memories in computer systems. However, the bandwidth of these electronic computers is limited by the signal delay of time constants important to electronic logic operations. In an attempt to mitigate these problems, scientists have considered the development of an optical digital computer, and one team has gone so far as to demonstrate the optical and electrical bistability for switching in a single transistor.

Eight children born - and the first robot-assisted operation performed. These are some of the results of 18 years of research at Sahlgrenska Academy on uterus transplants. In Gothenburg, the elite of the research world in the field are now gathering for their first congress.

In three years, from September 2014 to today, eight children in the world have been born to mothers who had fertilized eggs returned after undergoing a uterus transplant. All of this has taken place in the scope of the research conducted at Sahlgrenska Academy since 1999.

It turns out that when they're in a hurry and space is limited, ions, like people, will find a way to cram in -- even if that means defying nature's norms. Recently published research from an international team of scientists, including Drexel University's Yury Gogotsi, PhD, shows that the charged particles will actually forgo their "opposites attract" behavior, called Coulombic ordering, when confined in the tiny pores of a nanomaterial.

CAMBRIDGE, Mass. -- Two-dimensional materials called molecular aggregates are very effective light emitters that work on a different principle than typical organic light-emitting diodes (OLEDs) or quantum dots. But their potential as components for new kinds of optoelectronic devices has been limited by their relatively slow response time. Now, researchers at MIT, the University of California at Berkeley, and Northeastern University have found a way to overcome that limitation, potentially opening up a variety of applications for these materials.

New research links the equipping of mobile fruit and vegetable stands with wireless banking devices programmed to accept food stamps to the buying of more healthy foods by people with low incomes.

Boulder, Colo., USA: River deposits exist across the surface of Mars and record a surface environment from over 3.5 billion years ago that was able to support liquid water at the surface. A region of Mars named Aeolis Dorsa contains some of the most spectacular and densely packed river deposits seen on Mars.
