British researchers on Monday began collecting the DNA of residents from Normandy in northern France in search of Viking heritage, but the project has raised concerns amongst some local anti-racism activists. Around a hundred volunteers from the Cotentin Peninsula area are giving DNA samples to academics at the University of Leicester, who are trying to find descendants of the VikingsRead more

Dogs do not like people who are mean to their owners, Japanese researchers said Friday, and will refuse food offered by people who have snubbed their master. The findings reveal that canines have the capacity to co-operate socially -- a characteristic found in a relatively small number of species, including humans and some other primates. Researchers led by Kazuo Fujita,Read more

You may want to stop worrying about the filth in your boyfriend's beard and pay a little more attention to the toothbrush you stick in your mouth twice a day. According to a new study, toothbrushes in communal bathrooms are more than likely covered in fecal matter -- and potentially a haven for disease. Researchers at Quinnipiac University in ConnecticutRead more

A University of Michigan study of nearly 5,000 people found that experiencing a stroke alters memory and thinking speed as if the person had aged eight years overnight. Researchers were looking for an explanation for cognitive decline in older black people being about twice that of non-Hispanic white people, however in the case of strokes the decline is the same.Read more

A new two-pronged approach to treating antibiotic-resistant bacterial infections developed at Tel Aviv University has been shown in lab tests to kill off strains unaffected by antibiotics while making others more susceptible to the drugs. Using bacterial viruses called phages, researchers delivered edited DNA to the resistant strains, which kills them off, and eliminates the transfer of resistant genes betweenRead more

Teachers have a healthier lifestyle than the general population, however the stress level involved with the job is greater than many other professions and leads to psychological problems, according to a new study. Researchers at TU Dresden reviewed health data from for the 800,000 working teachers in Germany during the 2012-2013 school year and found that "burnout" is the greatestRead more

New research has developed a DNA-based blood test that can reveal every single virus that has ever invaded your body, the journal Science published Thursday. Scientists had been working on the test hoping that it will lead to early detection of various medical conditions and eventually help explain what triggers certain diseases and cancers. The test, called VirScan, takes aRead more

Iranian researchers from Shiraz University of Technology designed a nanocoating in a laboratorial research, which reduces inflammation caused by implants in the body. The nanocoating is made of biocompatible materials and has a long effective life due to its desirable properties. Results of the research have applications in tissue engineering. The mechanical behavior of nickel-titanium alloy is more close toRead more

Many years of research have shown that for students from lower-income families, standardized test scores and other measures of academic success tend to lag behind those of wealthier students. A new study led by researchers at MIT and Harvard University offers another dimension to this so-called "achievement gap": After imaging the brains of high- and low-income students, they found thatRead more

Breastfeeding a baby for at least six months may be linked to a lower risk of childhood leukemia, according to a review of previously published research on the topic Monday. The findings in the Journal of the American Medical Association (JAMA) Pediatrics suggest that breastfed babies have a 19 percent lower risk of the blood cancer compared to babies whoRead more
