No sedative necessary: Scientists discover new 'sleep node' in the brain

9/18/2014
BUFFALO, N.Y. A sleep-promoting circuit located deep in the primitive brainstem has revealed how we fall into deep sleep. Discovered by researchers at Harvard School of Medicine and the University at Buffalo School of Medicine and Biomedical Sciences, this is only the second "sleep node" id...

Miranda: An icy moon deformed by tidal heating

9/18/2014
Boulder, Colo., USA Miranda, a small, icy moon of Uranus, is one of the most visually striking and enigmatic bodies in the solar system. Despite its relatively small size, Miranda appears to have experienced an episode of intense resurfacing that resulted in the formation of at least thre...

Research milestone in CCHF virus could help identify new treatments

9/18/2014
SAN ANTONIO, September 18, 2014 New research into the Crimean-Congo hemorrhagic fever virus (CCHFV), a tick-borne virus which causes a severe hemorrhagic disease in humans similar to that caused by Ebolavirus, has identified new cellular factors essential for CCHFV infection. This discovery has the potential to lead to novel targets for therapeutic interventions against the pathogen. Th... [Comments]

Trial begins for MRI-compatible robot designed to improve accuracy of prostate biopsies

9/18/2014
Worcester, Mass. A novel robotic system that can operate inside the bore of an MRI scanner is currently being tested as part of a biomedical research partnership program at Brigham and Women's Hospital in Boston with the aim of determining if the robot, in conjunction with real-time MRI image...

Microplastic pollution discovered in St. Lawrence River sediments

9/18/2014
A team of researchers from McGill University and the Quebec government have discovered microplastics (in the form of polyethylene 'microbeads', Canadian Journal of Fisheries and Aquatic Sciences . The microbeads likely originate from cosmetics, household cleansers, or industrial cleansers, to which they are commonly added as abrasives. Owing to their small size and buoyancy, they may read...

Buzzing with activity: Fruit flies orbit Earth for science

9/18/2014
If the International Space Station ever starts a "frequent flyers" program, fruit flies surely would be eligible for platinum status. Recently the orbiting laboratory has hosted increasing numbers of fruit fly research studies. One fruit fly investigation returned from the space station in April...

Researchers study vital 'on/off switches' that control when bacteria turn deadly

9/18/2014
MADISON, Wis. No matter how many times it's demonstrated, it's still hard to envision bacteria as social, communicating creatures. But by using a signaling system called "quorum sensing," these single-celled organisms radically alter their behavior to suit their population. In short, some bacteria "know" how many of them are present, and act accordingly. Once the population of quor... [Comments]

Fall foliage season may be later, but longer on warmer Earth

9/18/2014
The fall foliage season that prompts millions of Americans to undertake jaunts into the countryside each year could come much later and possibly last a little longer within a century, according to new research. Climate change could postpone fall leaf peeping in some areas of the United State... [Comments]Fall foliage season may be later, but longer on warmer Earth

Language evolution: Quicker on the uptake

9/18/2014
The ability to acquire and creatively manipulate spoken language is unique to humans. "The genetic changes that occurred over the past 6 million years of human evolution to make this possible are largely unknown, but Foxp2 is the best candidate gene we now have," says Wolfgang Enard, Professor of Anthropology and Human Biology at LMU. In his efforts to understand the molecular biological basis... [Comments]

Scientists find how mysterious 'circular RNA' is formed, claim muscular dystrophy link

9/18/2014
Our genetic information is stored in DNA, tiny strands of nucleic acid that contain instructions for the functioning of our bodies. To express this genetic data, our DNA is copied into RNA molecules, which then translate the instructions into proteins that perform tasks in our cells. Several years ago, scientists discovered a new type of RNA molecule. Unlike all other known RNAs, this mole... [Comments]
