Cloned receptor paves way for new breast and prostate cancer treatment

Researchers at Uppsala University have cloned a T-cell receptor that binds to an antigen associated with prostate cancer and breast cancer. T cells that have been genetically equipped with this T-cell receptor have the ability to specifically kill prostate and breast cancer cells. The study is being published this week in PNAS.

Computer program can identify rough sketches

Computer scientists have developed a new program that can recognize rough sketches in real time, something that up to now had been very difficult for computers to do. To make the program work, the researchers used 20,000 real sketches to teach the program how humans actually sketch objects.

Daily disinfection of isolation rooms reduces contamination of healthcare workers' hands

New research demonstrates that daily cleaning of high-touch surfaces in isolation rooms of patients with Clostridium difficile or methicillin-resistant Staphylococcus aureus significantly reduces the rate of the pathogens on the hands of healthcare personnel. The findings underscore the importance of environmental cleaning for reducing the spread of difficult to treat infections. The study is...

Do SAT scores help or hurt in decisions about who will do well in college?

Every year, nervous high school juniors and seniors sit down and take the SAT. Their SAT scores will take on considerable importance over subsequent months, as college admissions teams choose incoming freshman classes. Some critics have argued that the SAT is biased against students who come from disadvantaged backgrounds and new research in Psychological Science puts that claim to the test....

Fruit flies reveal surprising new evolutionary link for studying human health

New research reveals that fruit flies and mammals may share a surprising evolutionary link in how they control body temperature through circadian rhythm, unlocking new ways to study the insects as models of human development and disease. The study posted online Sept. 13 by Current Biology reports that similar to people, Drosophila fruit flies have a genetically driven internal clock. This...

Genes render some rice species sterile

Researchers have identified a set of three genes that are responsible for hybrid sterility in rice, or the inability of many hybrid rice species to pass their genes on to the next generation. These findings inform a model that suggests how such hybrid sterility is maintained across rice species, and they may lead to the genetic improvement of rice as a food stock.

Gladstone scientists map the genomic blueprint of the heart

Scientists at the Gladstone Institutes have revealed the precise order and timing of hundreds of genetic "switches" required to construct a fully functional heart from embryonic heart cells -- providing new clues into the genetic basis for some forms of congenital heart disease.

Honestly? Just sign here -- first

Tax collectors and insurance agencies trying to boost honest reporting could improve compliance simply by asking people to sign their forms at the beginning instead of at the end. That's because attesting to the truthfulness of the information before a form is filled out tends to activate people's moral sense, making it harder for them to fudge their numbers after, says a new paper.

How early social deprivation impairs long-term cognitive function

Children who suffer severe neglect have cognitive impairments as adults. Study shows for the first time how functional impairments arise: Social isolation during early life prevents brain's white matter cells from maturing and producing myelin, the fatty "insulation" on nerve fibers, for transmitting long-distance messages in the brain. Study also identifies a molecular pathway involved, showing...

Immune system compensates for 'leaky gut' in inflammatory bowel disease susceptibility

New research could clarify how inflammatory bowel diseases (IBD), conditions that include ulcerative colitis and Crohn's disease, are triggered and develop. Scientists have shown how the immune system can compensate for a 'leaky gut' and prevent disease in mice that are susceptible to intestinal inflammation. These findings could explain why some individuals who are susceptible to developing IBD...

Increased dietary fructose linked to elevated uric acid levels and lower liver energy stores

Obese patients with type 2 diabetes who consume higher amounts of fructose display reduced levels of liver adenosine triphosphate -- a compound involved in the energy transfer between cells. The findings, published in the September issue of Hepatology, a journal of the American Association for the Study of Liver Diseases, indicate that elevated uric acid levels are associated with more severe...

Kids with food allergies can fall through the cracks

More can be done to properly manage the care of American children with food allergies, especially when it comes to diagnostic testing and recognizing non-visual symptoms of severe allergic reactions, according to a new Northwestern Medicine study.

Laser-powered 'needle' promises pain-free injections

From flu shots to immunizations, needle injections are among the least popular staples of medical care. A new laser-based system that blasts microscopic jets of drugs into the skin could soon make getting a shot as painless as being hit with a puff of air. The system uses a laser to propel a tiny, precise stream of medicine with just the right amount of force. The research was published today...
