Water is liquid at room temperature - astounding for such a small molecule. Insights into the causes are provided by a new simulation method, which has its origins in brain research.
Using artificial neural networks, researchers in Bochum and Vienna have examined the atomic interactions of water molecules. Based on their findings, they explain the melting temperature of ice and the density maximum at four degrees Celsius - based solely on computer simulations.
The case of Reo, a male chimpanzee that learned to walk again after being paralyzed due to illness, shows how much can be done to rehabilitate animals injured in captivity. So says lead author Yoko Sakuraba of Kyoto University, in an article in Primates, the official journal of the Japan Monkey Centre published by Springer.
BOSTON (July 5, 2016)--A study published today in the Journal of Neuroscience led by Yongjie Yang of Tufts University School of Medicine identifies an astroglial trigger mechanism as contributing to symptoms of fragile X syndrome in mice.
(Boston)--For the first time, researchers have determined that a brief, simple number naming test can differentiate between cognitively healthy elderly individuals and cognitively impaired people with Alzheimer's disease (AD), including those with mild cognitive impairment (MCI), as well as those with AD dementia. The study appears online in the journal Alzheimer's Disease and Associated Disorders, and was conducted by researchers at Boston University Alzheimer's Disease Center (BU ADC), with collaborators from Harvard Medical School and New York University School of Medicine.
CLEMSON, South Carolina -- A Clemson University psychology professor has published research revealing a positive link between mood, motivation and physical activity during work and study.
June J. Pilcher, alumni distinguished professor of psychology, studied the cognitive effects of physical activity workstations and traditional desks on Clemson student volunteers. The results of the study, published in Frontiers in Psychology, suggest the inclusion of light physical activity during work or study has positive effects without detracting from work or study effectiveness.
CHAMPAIGN, Ill. -- New research focuses on a fundamental human habit: When trying to explain something (why people give roses for Valentine's Day, for example), we often focus on the traits of the thing itself (roses are pretty) and not its context (advertisers promote roses). In a new study, researchers found that people who tend to focus on "inherent traits" and ignore context also are more likely to assume that the patterns they see around them are good.
The team reports its findings in the journal Psychological Science.
Researchers at University of California San Diego School of Medicine say tiny micro-vesicle structures used by neurons and other cells to transport materials internally or dispose of them externally carry tell-tale proteins that may help to predict the likelihood of mild cognitive impairment (MCI) developing into full-blown Alzheimer's disease (AD).
A new study authored by University of Calgary researchers in the Journal of Adolescence examines the pornography viewing habits of adolescents and observes the way in which religious attendance significantly tempers such actions.
Leading autism treatment provider, Center for Autism and Related Disorders (CARD), announced today a joint study with Chapman University about the effects of variables in treating autism spectrum disorder (ASD). The evaluation provides the most up-to-date, scientifically sound evidence to CARD and other autism therapy specialists in order to provide the best treatment to those with ASD.
BOSTON - A new risk calculator can predict an individual's risk of developing psychotic disorders such as schizophrenia, according to a new study published today in The American Journal of Psychiatry. The research involved collaborators from nine sites, including Beth Israel Deaconess Medical Center (BIDMC), and may help researchers test treatments to prevent onset of full psychosis.
OAK BROOK, Ill. - Machine learning is a type of artificial intelligence that allows computer programs to learn when exposed to new data without being programmed. Now, researchers in The Netherlands have coupled machine learning methods with a special MRI technique that measures the perfusion, or tissue absorption rate, of blood throughout the brain to detect early forms of dementia, such as mild cognitive impairment (MCI), according to a new study published online in the journal Radiology.
Sleeping king penguins react differently to the sounds of predators than to non-predators and other sounds, when they are sleeping on the beach. Research carried out at the University of Roehampton, UK, has revealed that even asleep, these penguins can distinguish between dangerous and benign sounds.
A team of neuroscientists at the Champalimaud Centre for the Unknown, in Lisbon, has been able to map single neural connections over long distances in the brain. "These are the first measurements of neural inputs between local circuits and faraway sites", says Leopoldo Petreanu, who led the research. In doing so, Petreanu and co-authors Nicolás Morgenstern and Jacques Bourg have also discovered that the wiring of the brain is more complex than previously thought. Their results have been published in the journal Nature Neuroscience.
Using a novel, newly developed mouse model that mimics the development of Alzheimer's disease in humans, Johns Hopkins researchers say they have been able to determine that a one-two punch of major biological "insults" must occur in the brain to cause the dementia that is the hallmark of the disease. A description of their experiments is published online in the journal Nature Communications.
Cleaner wrasse perform a cleaning service for coral reef fish -- namely eating parasites off their customer's skin. However, what the females of some species actually want is to lure in clients and 'cheat' them by biting off some tasty mucus before escaping.
