Toddlers regulate behavior to avoid making adults angry

When kids say "the darnedest things," it's often in response to something they heard or saw. This sponge-like learning starts at birth, as infants begin to decipher the social world surrounding them long before they can speak. Now researchers at the University of Washington have found that children as young as 15 months can detect anger when watching other people's social interactions and then use that emotional information to guide their own behavior. The study, published in the October/November issue of the journal, Cognitive Development, is the first evidence that ...

New 'lab-on-a-chip' could revolutionize early diagnosis of cancer

LAWRENCE — Scientists have been laboring to detect cancer and a host of other diseases in people using promising new biomarkers called "exosomes." Indeed, Popular Science magazine named exosome-based cancer diagnostics one of the 20 breakthroughs that will shape the world this year. Exosomes could lead to less invasive, earlier detection of cancer, and sharply boost patients' odds of survival. "Exosomes are minuscule membrane vesicles — or sacs — released from most, if not all, cell types, including cancer cells," said Yong Zeng, assistant professor ...

Study: Even motivated dieters need close access to healthy food

You're obese, at risk for diabetes and cardiovascular disease, and so motivated to improve your diet that you've enrolled in an intensive behavioral program. But if you need to travel more than a short distance to a store that offers a good selection of healthy food, your success may be limited. A new study from UMass Medical School and the Massachusetts Department of Public Health finds that not having close access to healthy foods can deter even the most motivated dieters from improving their diet, suggesting that easy access to healthy food is as important as personal ...

Very low concentrations of heavy metals and antibiotics contribute to resistance

New Swedish research shows that plasmids containing genes that confer resistance to antibiotics can be enriched by very low concentrations of antibiotics and heavy metals. These results strengthen the suspicion that the antibiotic residues and heavy metals (such as arsenic, silver and copper) that are spread in the environment are contributing to the problems of resistance. These findings have now been published in the highly regarded journal mBio. Antibiotic resistance is a growing medical problem that threatens human health worldwide. Why and how these resistant bacteria ...

Efficacy of potential therapy for autoimmune disorder of muscle weakness

PHILADELPHIA — Nearly 60,000 Americans suffer from myasthenia gravis (MG), a non-inherited autoimmune form of muscle weakness. The disease has no cure, and the primary treatments are nonspecific immunosuppressants and inhibitors of the enzyme cholinesterase. Now, a pair of researchers from the Perelman School of Medicine at the University of Pennsylvania have developed a fast-acting "vaccine" that can reverse the course of the disease in rats, and, they hope, in humans. Jon Lindstrom, PhD, a Trustee Professor in the department of Neuroscience led the study, published ...

Advocating weight diversity

A new review of the way health care professionals emphasise weight to define health and wellbeing suggests the approach could be harmful to patients. Author of the review article, Dr Rachel Calogero of the School of Psychology at the University of Kent, together with experts from other institutions and organisations, recommends that this approach, known as 'weight-normative', is replaced by health care professionals, public health officials and policy-makers with a 'weight-inclusive' approach. Weight-inclusive approaches, such as the Health At Every Size initiative, ...

Hospitalized patients don't wash their hands enough, study finds

Hamilton, ON (October 7, 2014) – Hospital visitors and staff are greeted with hand sanitizer dispensers in the lobby, by the elevators and outside rooms as reminders to wash their hands to stop infections, but just how clean are patients' hands? A study led by McMaster University researcher Dr. Jocelyn Srigley has found that hospitalized patients wash their hands infrequently. They wash about 30 per cent of the time while in the washroom, 40 per cent during meal times, and only three per cent of the time when using the kitchens on their units. Hand hygiene rates ...

The 'cyberwar' against cancer gets a boost from intelligent nanocarriers

Two years ago, Prof. Eshel Ben-Jacob of Tel Aviv University's School of Physics and Astronomy and Rice University's Center for Theoretical Biological Physics made the startling discovery that cancer, like an enemy hacker in cyberspace, targets the body's communication network to inflict widespread damage on the entire system. Cancer, he found, possessed special traits for cooperative behavior and used intricate communication to distribute tasks, share resources, and make decisions. In research published in the Early Edition of the Proceedings of the National Academy of ...

Anorexia/bulimia: A bacterial protein implicated

Eating disorders (ED) such as anorexia nervosa, bulimia, and binge eating disorder affect approximately 5-10% of the general population, but the biological mechanisms involved are unknown. Researchers at Inserm Unit 1073, "Nutrition, inflammation and dysfunction of the gut-brain axis" (Inserm/University of Rouen) have demonstrated the involvement of a protein produced by some intestinal bacteria that may be the source of these disorders. Antibodies produced by the body against this protein also react with the main satiety hormone, which is similar in structure. According ...

Gothenburg researchers identify molecule that protects women's eggs

A new study led by Professor Kui Liu at the University of Gothenburg has identified the key molecule 'Greatwall kinase' which protects women's eggs against problems that can arise during the maturation process. In order to be able to have a child, a woman needs eggs that can grow and mature. One of these eggs is then fertilised by a sperm, forming an embryo. During the maturation process, the egg needs to go through a number of stages of reductional division, called meiosis. If problems occur during any of these stages, the woman can become infertile. Around 10-15% of ...

Closing the gap: Extreme desert gecko spotted on salt-flats in central Oman

The Gulf Sand gecko is a remarkable desert reptile in that it is the only lizard found habitually on sabkha substrate across large parts of the eastern Arabian Peninsula. These arid salt flats constitute one of the harshest habitats on earth, due to their extraordinary salinity. The Gulf gecko, Pseudoceramodactylus khobarensis, belongs to a genus with a single species, and it is well adapted to this substrate featuring spiny scales beneath the fingers, long extremities and swollen nostrils. Data on its distribution range showed a conspicuous gap between eastern United ...

Sharing makes both good and bad experiences more intense

Undergoing an experience with another person — even if we do it in silence, with someone we met just moments ago — seems to intensify that experience, according to new research published in Psychological Science. The research shows that people who share experiences with another person rate those experiences as more pleasant or unpleasant than those who undergo the experience on their own. "We often think that what matters in social life is being together with others, but we've found it also really matters what those people are doing," says psychological scientist ...

NASA adds up Japan's soaking rains from Typhoon Phanfone

Typhoon Phanfone packed heavy rainfall as it brushed over Japan and NASA's TRMM satellite identified where the rain fell. That data was used to make a map of rainfall totals. The Tropical Rainfall Measuring Mission or TRMM satellite has the ability to calculate rainfall rates within storms as it orbits around the Earth's tropics from space. TRMM data can also be used to create rainfall maps that show how much rain has fallen over given areas. Phanfone was a powerful super typhoon with sustained wind speed estimated at 130 knots (150 mph) as it approached Japan but ...

Back off: Female chimps stressed out by competing suitors

Being the center of attention can have its drawbacks. For female chimpanzees, being around too many rowdy males is disadvantageous when foraging for food, an effect that can ultimately interfere with her reproductive ability. These are some of the findings of an 11-year-long study of wild East African chimpanzees in Uganda, led by Melissa Emery Thompson of the University of New Mexico in the US. It is published in Springer's journal Behavioral Ecology and Sociobiology. Female chimpanzees have an exceedingly slow reproductive schedule, and only give birth every five to ...
