An international consortium has shown for the first time evidence of substantial overlap of genetic risk factors shared between bipolar disorder, major depressive disorder and schizophrenia and less overlap between those conditions and autism and attention deficit-hyperactivity disorder, according...

Computer simulations have revealed how the electrical conductivity of many materials increases with a strong electrical field in a universal way. This development could have significant implications for practical systems in electrochemistry, biochemistry, electrical engineering and beyond. Fuente :...

Researchers have discovered how genetic mutations linked to Parkinson's disease might play a key role in the death of brain cells, potentially paving the way for the development of more effective drug treatments. In the new study, published in Nature Neuroscience, a team of researchers showed how...

A team of neuroscientists has identified a modification to a protein in laboratory mice linked to conditions associated with Alzheimer's disease. Their findings also point to a potential therapeutic intervention for alleviating memory-related disorders. Fuente :...

The growth of deadly plaque inside the walls of arteries may not happen as scientists believed, research from the University of Toronto and Massachusetts General Hospital has found.The research also suggests a new potential target in the treatment of atherosclerosis, a leading cause of...

Since the mid-1980s, unrestrained household spending has damaged American family finances -- despite the fact that globalization and technological change have caused consumer prices to fall widely, says Queens College sociologist Joseph Nathan Cohen. Fuente :...

An Indiana University study found that the percentage of votes for Republican and Democratic candidates in 2010 and 2012 races for the US House of Representatives could be predicted by the percentage of tweets that mentioned those candidates -- and it didn't matter whether the tweets were positive...

Chapman University's David Frederick will present new research at the 108th Annual Meeting of the American Sociological Association that examines men's and women's beliefs about who should pay for dates during courtship, and how couples actually go about splitting expenses. Fuente :...

Wealthier minorities were more likely to receive subprime loans than were affluent whites, according to a New York University study of Home Mortgage Disclosure Act data from 2006 -- the peak of the previous decade's housing boom. Moreover, black and Latino applicants were more likely to be denied...

Chemists have figured out how to synthesize nanomaterials with stainless steel-like interfaces. Their discovery may change how the form and structure of nanomaterials are manipulated, particularly those used for gas storage, heterogeneous catalysis and lithium-ion batteries. Fuente :...

New research on two promising gene therapies suggests that combining them into one treatment not only repairs muscle damage caused by Duchenne muscular dystrophy, but also prevents future injury from the muscle-wasting disease. The work is the first to look at the approach in aged mice, a key step toward clinical trials in...

A unique nanoscale drug that can carry a variety of weapons and sneak into cancer cells to break them down from the inside has a new component: a protein that stimulates the immune system to attack HER2-positive breast cancer cells. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/C...

Human triple-negative breast cancer can be treated by modulation of the opioid growth factor (OGF) - OGFr pathway. OGF suppresses cell growth by 20 percent within 24 hours in a receptor-mediated manner. Blockade of OGFr using low dosages of the opioid antagonist naltrexone causes a compensatory increase in OGF and results in 35...

An evolutionary ecologist is using "grains of sand" to understand more about the process of evolution. The fossils of microscopic aquatic creatures called planktonic foraminifera, often less than a millimeter in size, can be found in all of the world's oceans. The remains of their shells now resemble grains of sand to the naked...

One of the biggest mysteries in contemporary particle physics and cosmology is why dark energy, which is observed to dominate energy density of the universe, has a remarkably small (but not zero) value. Now, two physicists suggest that the Higgs boson could provide a possible "portal" to physics that could help explain some of...

A new analysis of dinosaur fossils has revealed that a number of specimens of the genus Psittacosaurus -- once believed to represent three different species -- are all members of a single species. The differences among the fossil remains that led other scientists to label them as separate species in fact arose from how the...

A new study has examined the effects of cigarette taxation on alcohol consumption. Results suggest that increases in cigarette taxes are associated with modest to moderate reductions in alcohol consumption among vulnerable groups. Vulnerable groups include hazardous drinkers, young adult smokers, and smokers in the lowest...

Researchers have long been aware of a phenomenon in speech called coarticulation, in which certain sounds are produced differently depending on the sounds that come before or after them. A new study suggests that piano paying also involves coarticulation, with hand muscle contractions differing depending on the sequence of...

We’ve known for well over a century that low blood oxygen causes altitude sickness. The origin of this idea has long been attributed to French researcher Paul Bert. But it’s really Bert’s benefactor, Denis Jourdanet, who deserves the credit, according to a new review article. Fuente :...
