Looking at the question of how social behavior has developed over the course of evolution, scientists from the universities in Mainz and Basel have gained new insights from the study of earwigs. "Young earwig offspring don't simply compete for food. Rather the siblings share what is available amongst themselves, especially when the mother is absent," explained Dr. Joël Meunier of the Evolutionary Biology section of the Institute of Zoology at Johannes Gutenberg University of Mainz (JGU).

When it comes to charitable giving, some countries open their collective wallets more than others. According to a new study in the Journal of Consumer Research, people who live in countries that promote equality in power and wealth are more likely to donate money than those who live in societies that expect and accept inequality.

Food is an intimately personal thing; we savor some tastes and despise others. But how does the way we chew and eat our food impact our overall consumption? According to a new study in the Journal of Consumer Research, people perceive foods that are either hard or have a rough texture to have fewer calories.

From sports to the stock market and even winning the lottery, it's in our nature to predict who or what will come out on top. But, sometimes we can't see the forest for the trees. According to a new study in the Journal of Consumer Research, people are more likely to make a prediction about something when it is grouped in a large category of similar items.

In a recent analysis by the RECIST Working Group published in the European Journal of Cancer, EORTC researchers had explored whether a more refined categorization of tumor response or various aspects of progression could improve prediction of overall survival in the RECIST database. They found that modeling target lesion tumor growth did not improve the prediction of overall survival above and beyond that of the other components of progression.

Case Western Reserve University dental researchers have found a less invasive way to extract single rare immune cells from the mouth to study how the mouth's natural defenses ward off infection and inflammation.

By isolating some specialized immune cells (white blood cells known as "leukocytes") to study how they fight diseases in the mouth—or reject foreign tissues, such as in failed organ transplants—researchers hope to learn more about treating and preventing such health issues as oral cancers, cardiovascular disease, AIDS and other infectious diseases.

WINSTON-SALEM – April 15, 2014 – Vitamin D deficiency and cognitive impairment are common in older adults, but there isn't a lot of conclusive research into whether there's a relationship between the two.

A new study from Wake Forest Baptist Medical Center published online ahead of print this month in the Journal of the American Geriatrics Society enhances the existing literature on the subject.

WASHINGTON, DC, April 15, 2014 — A new study reveals that for adolescent girls, having a romantic relationship play out differently than they imagined it would has negative implications for their mental health.

"I found that girls' risk of severe depression, thoughts of suicide, and suicide attempt increase the more their relationships diverge from what they imagined," said the study's author Brian Soller, an assistant professor of sociology and a senior fellow of the Robert Wood Johnson Foundation Center for Health Policy at the University of New Mexico.

Biologists at UC San Diego have succeeded in visualizing the movement within plants of a key hormone responsible for growth and resistance to drought. The achievement will allow researchers to conduct further studies to determine how the hormone helps plants respond to drought and other environmental stresses driven by the continuing increase in the atmosphere's carbon dioxide, or CO2, concentration.

A new study from the Faculty of Medicine & Dentistry is looking at nurse- and pharmacist-led interventions to improve the standard of care for patients who have suffered minor stroke or transient ischemic attack, also known as "mini stoke."

Infection is bad news for all of us - but it can be really serious to people who have had a stroke. Evidence is mounting that infection makes things much worse after a stroke.

A team of scientists at the University of Manchester has now found a key to why and how infection is such a bad thing for stroke sufferers

In the research published today in the medical journal Annals of Neurology, the researchers show that rodents with pneumonia fared worse after having a stroke than those without the bacterial infection.

NAIROBI, Kenya (9 April 2014) -----Formalizing trade in herbal medicinal products has the potential to increase the demand for on-farm grown raw material and raise the level of cultivation of medicinal tree species in smallholder farms.

A study carried out by the World Agroforestry Centre (ICRAF) in Kenya shows that trade in herbal medicinal products is rising in the urban areas and formalization in terms of better hygienic packaging and labeling of the products is likely to increase cultivation of these tree species.

There are many viral diseases in the world for which no pharmaceutical treatment exists. These include, among others, dengue fever, which is spread by mosquitoes in the tropics, as well as a type of diarrhea, which is more familiar in Finland and is easily spread by the hands and can be dangerous especially for small children and the elderly.

University of Adelaide research into parasites of cuttlefish, squid and octopus has uncovered details of the parasites' astonishing life cycles, and shown how they may help in investigating populations of their hosts.

Researcher Dr Sarah Catalano has described 10 new parasite species− dicyemid mesozoans −, which live in the kidneys of cephalopods (cuttlefish, squid and octopus). They are the very first dicyemid species to be described from Australian waters.

Engineers at the University of California, San Diego, have created new ceramic materials that could be used to store hydrogen safely and efficiently.

The researchers have created for the first time compounds made from mixtures of calcium hexaboride, strontium and barium hexaboride. They also have demonstrated that the compounds could be manufactured using a simple, low-cost manufacturing method known as combustion synthesis.
