Scientists have linked more than 100 spots in our DNA to the risk of developing schizophrenia, casting light on the mystery of what makes the disease tick. Such work could eventually point to new treatments, although they are many years away.
Experimentation with human growth hormones by America's teens more than doubled in the past year, as more young people looked to drugs to boost their athletic performance and improve their looks, according to a new, large-scale national survey. In a confidential 2013 survey of 3,705 high school...
Nearly a third of children in a national survey didn't have an accurate idea of their own weight — most of them heavy or obese children who viewed themselves as normal. These false impressions were more common in black and Mexican-American children than in white kids, the survey found. Some...
Parts of a northern Chinese city have been quarantined after state media said a man there died of bubonic plague. The Chinese news agency Xinhua said Tuesday that 151 people were under observation in the city of Yumen in Gansu province after authorities determined they had come in contact with a man who had died of the plague July 16.
ASU graduate student Krupa Navalkar is the lead author of a new study describing a promising strategy known as immunosignaturing, which can provide clinicians with an accurate identification of valley fever, a potentially serious affliction that is often misdiagnosed. read more
A Central California company is recalling specific lots of its fresh peaches, plums, nectarines and pluots sold nationwide over concerns of possible listeria contamination. Wawona Packing Co. President Brent Smittcamp said in a statement that he is not aware of any illnesses caused by the fruit,...
The PlateReader AF2200 from Eppendorf is specially designed for UV/Vis and fluorescence (top and bottom) readings in 6- to 384-well format.
The seriousness of disease often results from the strength of immune response, rather than with the virus, itself. Turning down that response, rather than attacking the virus, might be a better way to reduce that severity. Researchers have taken the first step in doing that for the H7N9 influenza, and their work has led to identification of six potential therapeutics for this highly virulent strain.
Viruses designed to target and kill cancer cells could boost the effectiveness of chemotherapy to the arms and legs and help avoid amputation. Scientists tested the effectiveness of a genetically engineered version of the virus used to vaccinate against smallpox. They found use of the virus alongside isolated limb perfusion chemotherapy was more effective in rats than either treatment on its own.
Teachers-in-training have long been taught that the fourth grade is when students stop learning to read and start reading to learn. But a new study tested the theory by analyzing brain waves and found that fourth-graders do not experience a change in automatic word processing. Instead, some types of word processing become automatic before fourth grade, while others don’t switch until after fifth.
Many bacteria swim using flagella, corkscrew-like appendages that push or pull bacterial cells like propellers. It had been assumed that the flagella do all the work during swimming, while the rest of the cell body is just along for the ride. But new research shows that in at least one species, the cell body is actively carving out a helical trajectory through the water that produces thrust and contributes to the organism's ability to swim.
A new study in mice reveals that mesenchymal stem cells (MSCs) help rejuvenate skeletal muscle after resistance exercise. By injecting MSCs into mouse leg muscles prior to several bouts of eccentric exercise, researchers were able to increase the rate of repair and enhance the growth and strength of those muscles in the exercising mice.
The HIV-1 virus has proved to be tenacious, inserting its genome permanently into its victims' DNA, forcing patients to take a lifelong drug regimen to control the virus and prevent a fresh attack. Now, a team of Temple University School of Medicine researchers has designed a way to snip out the integrated HIV-1 genes for good.
Eating probiotics regularly may modestly improve your blood pressure, according to new research. Probiotics are live microorganisms (naturally occurring bacteria in the gut) thought to have beneficial effects; common sources are yogurt or dietary supplements.
Mixed genes appear to drive hybrid birds to select more difficult routes than their parent species, according to new research from University of British Columbia zoologists. the researchers harnessed a flock of B.C. Swainson’s thrushes with tiny geolocating backpacks to map their routes as they migrated south through the U.S. to Central and South America.
