When Dr. Irene Gatti de Leon slipped on the ice and bumped her head, she wasn't too concerned. But two months later, she began to experience weakness in her right leg and right arm while she and her husband were visiting their daughter in suburban C
When you cannot become a parent without outside help, making decisions to deal with your longing is a complicated process. This is shown in a new doctoral thesis at the Nordic School of Public Health NHV. "Accepting that you need to seek help t
A survey on the mental health of eight-year-old children could help identify those individuals who are highly likely to require psychiatric treatment in their teens or early adulthood, shows a study conducted at the University of Helsinki. Should &q
Parents generally teach their children about "stranger danger" from an early age, telling them not to talk to, walk with or take gifts or candy from strangers. But statistics show danger often lurks closer to home. According to numbers pro
A recent discovery of "hypervirulent" Salmonella bacteria has given UC Santa Barbara researchers Michael Mahan and Douglas Heithoff a means to potentially prevent food poisoning outbreaks from these particularly powerful strains.

Scientists have identified which strains of the Toxoplasma gondii parasite, the cause of toxoplasmosis, are most strongly associated with premature births and severe birth defects in the United States. The researchers used a new blood test developed
Researchers at Murdoch University have used new DNA sequencing technology to reveal the animal and plant composition of traditional Chinese medicines (TCMs). Some of the TCM samples tested contained potentially toxic plant ingredients, allergens, an
Expanding on previous research providing proof-of-principle that human stem cells can be genetically engineered into HIV-fighting cells, a team of UCLA researchers have now demonstrated that these cells can actually attack HIV-infected cells in a li
A team of researchers at Case Western Reserve University School of Medicine have identified a new mechanism by which colon cancer develops. By focusing on segments of DNA located between genes, or so-called "junk DNA," the team has discove
The specific mechanisms by which humans and other animals are able to discriminate between disease-causing microbes and innocuous ones in order to rapidly respond to infections have long been a mystery to scientists. But a study conducted on roundwo
About 300,000 years ago humans adapted genetically to be able to produce larger amounts of Omega-3 and Omega-6 fatty acids. This adaptation may have been crucial to the development of the unique brain capacity in modern humans. In today’s life
Scientists at the Allen Institute for Brain Science have identified similarities and differences among regions of the human brain, among the brains of human individuals, and between humans and mice by analyzing the expression of approximately 1,000
What happens to a stem cell at the molecular level that causes it to become one type of cell rather than another? At what point is it committed to that cell fate, and how does it become committed? The answers to these questions have been largely unk
In a paper published April 12 in the journal Cell, a team from the University of North Carolina at Chapel Hill unveils the first broad-based test for activation of protein kinases "en masse," enabling measurement of the mechanism behind dr
Researchers at the University of California, Davis, have discovered a key tool that helps sperm and eggs develop exactly 23 chromosomes each. The work, which could lead to insights into fertility, spontaneous miscarriages, cancer and developmental d
Maintaining the right level of sugar in the blood is the responsibility not only of insulin, which removes glucose, but also of a hormone called glucagon, which adds glucose. For decades, treatments for type II diabetes have taken aim at insulin, bu
Attitude may play an important role in how exercise affects menopausal women, according to Penn State researchers, who identified two types of women -- one experiences more hot flashes after physical activity, while the other experiences fewer.
Overuse injuries -- found most often in low-contact sports that involve long training sessions or where the same movement is repeated numerous times -- make up nearly 30 percent of all injuries sustained by collegiate athletes.
There is a connection between phthalates found in cosmetics and plastics and the risk of developing diabetes among seniors. Even at a modest increase in circulating phthalate levels, the risk of diabetes is doubled. This conclusion is drawn by resea

In spite of considerable research efforts around the world, we still do not know the determining factors that confer stem cells their main particular features: capacity to self-renew and to divide and proliferate. The scientist Jordi Casanova, head
