Oxytocin's effects on human social behavior aren't clear. Some studies reveal significant positive changes, yet others show none at all. In many animals, from rodents to non-human primates, it's a different story: Oxytocin has been proven to increase positive social behaviors and attention paid to others, and reduce negative social behaviors like threats and vigilance.
Among homeless individuals cardiovascular disease remains one of the major causes of death due to challenges in predicting initial risk, limited access to health care and difficulties in long-term management, according to a review published today in the Journal of the American College of Cardiology.
TORONTO, May 28, 2018 - The most commonly consumed vitamin and mineral supplements provide no consistent health benefit or harm, suggests a new study led by researchers at St. Michael's Hospital and the University of Toronto.
Dwarf mongooses remember previous cooperative acts by their groupmates and reward them later, according to new work by University of Bristol researchers, published today in the journal Proceedings of the National Academy of Sciences USA.
Market trade was once considered the domain of humans but the exchange of goods and services is now widely recognised in other animals. What the new research shows is that mongooses have sufficient cognitive ability to quantify earlier acts of cooperation and to provide suitable levels of delayed rewards.

Like humans, cells of the same species each have a distinct "personality." When confronted with an external stimulus like a virus, they each secrete a different quantity of molecules and communicate with each other to a varying degree. Studies have already shown that two cells of the same type may not behave identically when subjected to the same treatment.
A community-based health promotion program developed by McMaster University that was offered by paramedics in low-income apartment buildings significantly reduced the number of 911 calls and improved quality of life for seniors, found a randomized controlled trial published in CMAJ (Canadian Medical Association Journal)
New research presented at this year's European Congress on Obesity (ECO) in Vienna, Austria (23-26) May shows chewing gum while walking increases heart rate and energy expenditure. The study was conducted by Dr Yuka Hamada and colleagues at Waseda University, Graduate School of Sport Sciences, Saitama, Tokyo, Japan.
Although there have been a number of studies which have examined the effect of chewing gum on physiological functions while at rest, none have focused specifically on how it impacts the body while walking, which is the basis for this study.
New research on different colours and shapes of bread, presented at this year's European Congress on Obesity in Vienna, Austria (23-26 May), shows that star-shaped bread is particularly popular with young children and could help them make healthy food choices. The study is by Dr Marlies Wallner and Bianca Fuchs-Neuhold, Health Perception Lab, Institute of Dietetics and Nutrition, FH JOANNEUM University of Applied Sciences, Bad Gleichenberg, Austria, and colleagues.
A new study, affiliated with UNIST has recently presented a novel statistical algorithm, capable of identifying potential disease genes in a more accurate and cost-effective way. This algorithm has also been considered as a new promising approach for the identification of candidate disease genes, as it works effectively with less genomic data and takes only a minute or two to get results.
Indigenous communities are rejecting non-indigenous energy projects in favour of community-led sustainable energy infrastructure.
The switch has led to some improvements in economic and social development as well as capacity-building for self-governance, according to a study from the University of Waterloo.
Iridescence is a form of structural colour which uses regular repeating nanostructures to reflect light at slightly different angles, causing a colour-change effect.
It is common in nature, from the dazzling blues of peacock's feathers, to the gem-like appearance of insects.
Young adults are less likely to buy sugar-sweetened beverages that include health labels, particularly those with graphic warnings about how added sugar can lead to tooth decay, obesity, and type 2 diabetes.
The new research, being presented at this year's European Congress on Obesity (ECO) in Vienna, Austria (23-26 May), also indicates that individuals are more likely to choose healthier options if there is a Health Star Rating displayed on beverages. The Health Star Rating is the national front-of- pack labelling system in use in Australia and New Zealand.
New research investigating the legality of on-pack nutrition and health claims routinely found on commercially available meal replacement shakes for sale in the UK, reveals that more than three-quarters are unauthorised and do not comply with the EU Nutrition and Health Claims regulation.
This is one of the first studies to analyse how on-pack claims stack up to current regulation, and how much consumers actually understand and are influenced by such claims, and is being presented at this year's European Congress on Obesity (ECO) in Vienna, Austria (23-26 May).
