Intermittent fasting, and fasting in general, has been a popular fad health gimmick, but the science isn't on its side. Instead, proponents believe mice are little people so if mice weaned on starvation diets lived longer, people would also.
Goats have the capacity to communicate with people like other domesticated animals, such as dogs and horses, according to scientists from Queen Mary University of London (QMUL).
In a new paper in the journal Biology Letters, researchers from QMUL's School of Biological and Chemical Sciences found that goats respond to people by gazing at them when facing a problem they cannot solve alone, and their responses change depending on the person's behaviour.
To investigate, the team trained goats to remove a lid from a box to receive a reward. In the final test, they made the reward inaccessible and recorded their reaction towards the experimenters, who were either facing the goats or had their backs to them.
The woman was laid on a bed of specially selected materials, including gazelle horn cores, fragments of chalk, fresh clay, limestone blocks and sediment. Tortoise shells were placed under and around her body, 86 in total. Sea shells, an eagle's wing, a leopard's pelvis, a forearm of a wild boar and even a human foot were placed on the body of the mysterious 1.5 meter-tall woman. Atop her body, a large stone was laid to seal the burial space.
Tobacco and cannabis are two of the world's most popular drugs, used respectively by 1 billion and 182 million people worldwide (World Health Organization; United Nations Office on Drugs and Crime). The adverse health effects of tobacco are well known. Short-term effects of cannabis are transient impairments in motor function and working memory, planning, and decision-making, while possible long-term health effects of heavy cannabis use include physical and psychological dependence, permanent reductions in cognitive performance, cardiovascular and respiratory diseases, and some cancers (WHO).
Hamilton, ON (July 5), 2016 -- Ads for unhealthy foods and beverages high in sugar or salt have an immediate and significant impact on children and lead to harmful diets, according to research from McMaster University.
The study, published today in the scientific journal Obesity Reviews, examined 29 trials assessing the effects of unhealthy food and beverage marketing and analyzing caloric intake and dietary preference among more than 6000 children. Researchers found that the marketing increased dietary intake and influenced dietary preference in children during or shortly after exposure to advertisements.
More than 4,000 years ago, a proto-globalization process started in the Indian Ocean, one of the outcomes being a great human migration of African and Asian peoples spreading across the Indian Ocean to inhabit the fourth largest island in the world, Madagascar. Austronesian peoples came from Borneo on boats, and Bantu migrants crossed over from East Africa. Overall, the Malagasy is thought to be composed by more than a dozen of ethnic groups, and the specific geographic, linguistic origins and settlement dates are still hotly debated.
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.
In their normal work, researchers of the Primate Research Institute at Kyoto University use chimpanzees' interaction with computers and touch screens to study the cognition and perception of these primates. When Reo was paralyzed from the neck down, dedicated staff put this technology to further use by encouraging the animal to walk again. This is the first case in which a paralyzed chimpanzee has been rehabilitated through such a dedicated programme.
During the Pamplona, Spain, "Running of the Bulls" you won't need all of the ambulances that are placed along the route, so how do event organizers know where they should be? Statistics helps know.
Experts have studied the bull runs of the last six years (a total of 48 races) in order to identify the risks that exist. As you might anticipate, absent an extraordinary event, like a terrorist attack or alien invasion, the risk to one set, the runners and the bulls, are the bulls themselves, the runners and the route. Runners may incur slight injuries such a falls, scratches or breakages, or even being gored. The bulls can suffer physical consequences such as broken horns or hooves.
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.
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.
Psychosis is characterized by hallucinations and delusions. The new calculator assesses an individual's risk of developing psychosis after experiencing early warning signs of schizophrenia, such as hearing voices.
A new paper in the Journal of Adolescence finds that adolescents attending religious services has a positive affect on reducing pornography viewing.
Baltimore, MD-- As we age, the function and regenerative abilities of skeletal muscles deteriorate, which means it is difficult for the elderly to recover from injury or surgery. New work from Carnegie's Michelle Rozo, Liangji Li, and Chen-Ming Fan demonstrates that a protein called b1-integrin is crucial for muscle regeneration. Their findings, published by Nature Medicine, provide a promising target for therapeutic intervention to combat muscle aging or disease.
Octopuses, squid and other cephalopods are colorblind - their eyes see only black and white - but their weirdly shaped pupils may allow them to detect color and mimic the colors of their background, according to a father/son team of researchers from the University of California, Berkeley, and Harvard University.
For decades, biologists have puzzled over the paradox that, despite their brilliantly colored skin and ability to rapidly change color to blend into the background, cephalopods have eyes containing only one type of light receptor, which basically means they see only black and white.
