Humans naturally cooperative, altruistic, social

The condition of man is a condition of war, wrote 17th-century philosopher Thomas Hobbes. A quick glance through history books and today's news headlines certainly seems to support the longstanding idea that humans by nature are aggressive, selfish and antagonistic.

Improvements are needed for accuracy in gene-by-environment interaction studies

A new study from McLean Hospital/Harvard Medical School and the University of Colorado concludes that genetic research drawing correlations between specific genes, environmental variables and the combined impact they have on the development of some psychiatric illnesses needs additional scrutiny and replication before being accepted as true.

Is estrogen going to your head?

Girls are growing up faster than ever – and not only when it comes to their taste in fashion and music. Their bodies are reaching puberty at an increasingly earlier age, and this trend to rapid maturity continues through women's adult lives. That's bad news, according to Tel Aviv University researchers. Women today are more likely to develop Hyperostosis Frontalis Interna (HFI), a hormonal...

Legume ipmPIPE: A new option for generating, summarizing and disseminating real-time pest data

A new, open-access article in the Journal of Integrated Pest Management describes the background, usage, and value of the Legume Integrated Pest Management Pest Information Platform for Extension and Education (ipmPIPE). The goal of the Legume ipmPIPE is to identify causes of losses (yield, quality, economic) in legumes and assist producers in minimizing those losses by implementing integrated...

Microsoft, Acer in patent license agreement

Microsoft said Thursday it has reached a patent license agreement with Acer, Taiwan's leading computer maker, that will cover tablet computers and smartphones powered by Google's Android platform.

Mutation links inherited narcolepsy with multiple neuropsychiatric disorders

Narcolepsy is a rare disorder characterized by an excessive urge to sleep at inappropriate times and places. Narcoleptics are also often subject to "cataplexy," a sudden muscle weakness that is triggered by strong emotions. Although most cases of narcolepsy are thought to be caused by complex mechanisms, a small percentage of cases are associated with unidentified inherited mutations. Now, a new...

New method to grow synthetic collagen unveiled

In a significant advance for cosmetic and reconstructive medicine, scientists at Rice University have unveiled a new method for making synthetic collagen. The new material, which forms from a liquid in as little as an hour, has many of the properties of natural collagen and may prove useful as a scaffold for regenerating new tissues and organs from stem cells.

New report: US investment in health research remains stagnant

The U.S. public and private sectors invested $140.5 billion in 2010 on research to find new ways to treat, cure and prevent disease and disability, according to Research!America's latest annual estimate, available at http://www.researchamerica.org/uploads/healthdollar10.pdf.

Researchers identify insect host species of a famous Tibetan medicinal fungus

A team of researchers from the Institute of Microbiology, Chinese Academy of Sciences (Xiao-Liang Wang and Yi-Jian Yao), summarized all the available information on the insect species associated with the Tibetan medicinal fungus Ophiocordyceps sinensis through an extensive literature survey and analyzed their relationships with the fungus. The study was published in the open access journal...

Researchers probe genetic link to blindness

University of Leeds researchers have used next-generation DNA sequencing techniques to discover what causes a rare form of inherited eye disorders, including cataracts and glaucoma, in young children.

Scientists discover genetic mutation that causes Parkinson's disease

A large team of international researchers have identified a new genetic cause of inherited Parkinson's disease that they say may be related to the inability of brain cells to handle biological stress. The study, published in the September issue of the American Journal of Human Genetics, continues to fill in the picture of Parkinson's disease as a complex disorder influenced by multiple genes, say...

Sediba hominid skull hints at later brain evolution

An analysis of a skull from the most complete early hominid fossils ever found suggests that the large and complex human brain may have evolved more rapidly than previously realized, and at a later time than some other human characteristics.

Targeted policing has knock-on benefits

With the police service undergoing budget reductions, and calls for more officers on the streets, a new study offers some reassuring conclusions. Researchers at UCL's Department of Security and Crime Science found no evidence that successful police crime prevention activity, such as problem-oriented policing, results in problems being moved elsewhere (as sceptics argue). In fact, the study...

Team applies new techniques and sees surprises in cell division

Researchers at the California Institute of Technology have obtained the first high-resolution, three-dimensional images of a cell with a nucleus undergoing cell division. The observations, made using a powerful imaging technique in combination with a new method for slicing cell samples, indicate that one of the characteristic steps of mitosis is significantly different in some cells.
