More men than women develop Parkinson’s disease and new work presented at the Federation of European Neuroscience Societies says that it is do to sex differences in how brain cells change. Parkinson’s disease affects about 9 million people and becomes increasingly prevalent with age.
ANN ARBOR, Mich -- Nearly half of parents whose child had leftover pain medication from a surgery or illness say they kept the prescription opioids at home -- representing a potential problem down the line.
Parents whose child's provider discussed what to do with the pills, however, were far more likely to dispose them properly, according to a report from the C.S. Mott Children's Hospital National Poll on Children's Health.
CHAMPAIGN, Ill. -- A new study reveals that police recruits and experienced officers are more likely than others to subscribe to colorblind racial beliefs -- the notion that they - and people in general -- see no differences among people from different racial groups and treat everyone the same.
The findings appear in the journal Race and Social Problems.
The U.S. police force is roughly 75 percent white and male, said University of Illinois anthropology professor Cris Hughes, who led the research with colleagues in anthropology, psychology, advertising and the U. of I. Police Training Institute.
Scientists have found evidence of a huge asteroid that struck the Earth early in its life with an impact larger than anything humans have experienced.
Tiny glass beads called spherules, found in north-western Australia were formed from vaporised material from the asteroid impact, said Dr Andrew Glikson from The Australian National University (ANU).
"The impact would have triggered earthquakes orders of magnitude greater than terrestrial earthquakes, it would have caused huge tsunamis and would have made cliffs crumble," said Dr Glikson, from the ANU Planetary Institute.
As climatologists closely monitor the impact of human activity on the world's oceans, researchers at the Georgia Institute of Technology have found yet another worrying trend impacting the health of the Pacific Ocean.
A new modeling study conducted by researchers in Georgia Tech's School of Earth and Atmospheric Sciences shows that for decades, air pollution drifting from East Asia out over the world's largest ocean has kicked off a chain reaction that contributed to oxygen levels falling in tropical waters thousands of miles away.
SAR11 are the most abundant plankton in the world's oceans. They are also a massive source of two sulfur gases that play important roles in the Earth's atmosphere.
Scientists at the University of East Anglia have discovered how a tiny yet abundant ocean organism helps regulate the Earth's climate.
Research published today in Nature Microbiology reveals how a bacterial group called 'Pelagibacterales' plays an important function in keeping the Earth's atmosphere stable.
The project was led by Prof Steve Giovannoni and Dr Jing Sun at Oregon State University, in collaboration with researchers from UEA among others.
They showed that these tiny, hugely abundant bacteria could make the environmentally important gas, dimethyl sulfide. Researchers at UEA identified and characterised the gene that is responsible for this property.
Physicists are putting themselves out of a job, using artificial intelligence to run a complex experiment.
The experiment, developed by physicists from The Australian National University (ANU) and UNSW ADFA, created an extremely cold gas trapped in a laser beam, known as a Bose-Einstein condensate, replicating the experiment that won the 2001 Nobel Prize.

A new study by the University of Liverpool's Institute of Ageing and Chronic Disease has identified food stuffs that can help prevent chronic inflammation that contributes to many leading causes of death.
Inflammation occurs naturally in the body but when it goes wrong or goes on too long, it can trigger disease processes. Uncontrolled inflammation plays a role in many major diseases, including cancer, heart disease, diabetes and Alzheimer's disease.
Diets rich in fruits and vegetables, which contain polyphenols, protect against age-related inflammation and chronic diseases.

A new study has implicated farms as a bigger source of fine-particulate air pollution than all other sources. This is no surprise in Europe, China, Russia and Europe, since food is the most important strategic resource everywhere.
And it's an easy enough problem to solve. As technology continues to improve, emissions will go down anyway, so fumes from nitrogen-rich fertilizers and animal waste that combine in the air with industrial emissions to form solid particles could double and particulate matter would still go down.
COLUMBUS, Ohio - Nearly everybody thinks that presidential candidates routinely dodge hard-hitting questions, providing evasive answers to simple questions.
But a new study that analyzed the full transcripts of 14 U.S. presidential debates from 1996 to 2012 provides some surprising insights that might temper that belief -- and help explain why people believe politicians are evasive.
The research found that presidential candidates accused their rivals of evasion quite often -- 54 times in the 14 debates analyzed.
But rivals were actually guilty of some form of evasion no more than 35 percent of the time that they were accused, the study found.
Researchers at Vanderbilt University Medical Center have discovered a potential way to "tune up" the immune system's ability to kill cancer cells.
In a paper published recently, Eric Sebzda, Ph.D., assistant professor of Pathology, Microbiology and Immunology, graduate student and first author Whitney Rabacal and colleagues describe their discovery in mice of a tolerance mechanism that restrains the activity of natural killer (NK) cells, and a potential way to overcome it.
With an advance that one cryptography expert called a "masterpiece," University of Texas at Austin computer scientists have developed a new method for producing truly random numbers, a breakthrough that could be used to encrypt data, make electronic voting more secure, conduct statistically significant polls and more accurately simulate complex systems such as Earth's climate.
The new method creates truly random numbers with less computational effort than other methods, which could facilitate significantly higher levels of security for everything from consumer credit card transactions to military communications.
