Scientists have identified a unique class of breast cancer cells that lead the process of invasion into surrounding tissues, the first step in the deadly process of cancer metastasis, and have found a way to stop that invasion process in mice.
A statistical analysis using the natural and orthogonal interaction (NOIA) model may be a better...
A new finding by scientists has identified key steps that trigger the disintegration of cellular...
Two very different recent papers come to a similar conclusion: cyclical, physiologic hormone...
A research team has identified variations, found in a gene never before linked to Alzheimer’s, that doubles a person’s risk of developing the disease later in life.
Citing a potential threat to public health, the Food and Drug Administration is taking steps toward phasing out the use of some antibiotics in animals processed for meat.
Tens of thousands of women each year might be able to skip at least some of the grueling treatments for breast cancer— which can include surgery, heavy chemo and radiation— without greatly harming their odds of survival, new research suggests.
British Prime Minister David Cameron says he hopes to kick-start an international effort to find a cure or effective treatment for dementia by 2025.
Researchers have determined the structure of the rubella virus capsid protein, which is central to the virus's ability to assemble into an infectious particle and to infect humans.
Researchers reported that a virulent new strain of influenza appears to retain its ability to cause serious disease in humans even after it develops resistance to antiviral medications.
Mothers typically get all the attention, but a new study suggests that the father’s diet before conception may play an equally important role in the health of their offspring.
Researchers have discovered a gene that may reveal whether people are likely to respond well to SSRI antidepressants, both generally and in specific formulations.
Global efforts to curb malaria are stalling after a drop in funds to buy bed nets, according to the latest report Wednesday from the World Health Organization. In 2010, 145 million bed nets were distributed; that fell to 92 million in 2011 and 70 million last year.
Researchers have found that a new kind of gene therapy led to a dramatic decline in bleeding events in dogs with naturally occurring hemophilia A.
A protein called Tet1 is partly responsible for giving primordial germ cells a clean epigenetic slate before developing into sperm and egg cells, according to a new study.
Blood clots play an unexpected role in protecting the body from the deadly effects of bacteria by absorbing bacterial toxins, researchers have found.
A new computational model developed by MIT neuroscientists explains how the brain maintains the balance between plasticity and stability, and how it can learn very similar tasks without interference between them.
A new study show that in mice with a rodent form of multiple sclerosis (MS), vitamin D appears to block damage-causing immune cells from migrating to the central nervous system.
Researchers have uncovered a genetic deficiency in males that can trigger the development of one of the most common types of liver cancer and forms of diabetes.
After conducting a major review of evidence, the European Food Safety Authority has found that the artificial sweetener aspartame is safe for people to consume at the levels currently used in diet soft drinks.
Harmless lung cancer? A provocative study found that nearly 1 in 5 lung tumors detected on CT scans are probably so slow-growing that they would never cause problems.
A new microchip-based device may greatly simplify the monitoring of patients’ response to treatment for ovarian cancer— the most lethal form of gynecologic cancer— and certain other malignancies.
Researchers reported promising outcomes data for the first group of boys with X-linked severe combined immunodeficiency syndrome (SCID-X1), a fatal genetic immunodeficiency also known as "bubble boy" disease, who were treated as part of an international clinical study of a new form of gene therapy.
There is more than meets the eye following even a mild traumatic brain injury. While the brain may appear to be intact, new findings report that the brain’s protective coverings may feel the brunt of the impact.
New demographic data on humans, animals and plants for the first time unveils such an extraordinary diversity of aging processes that no existing evolutionary theory can account for it.
A new research program will investigate the relationship between exposure to environmental tobacco smoke during pregnancy and childhood and attention deficit hyperactivity disorder (ADHD) in children.
Yes, our prehistoric ancestors had to fend off saber-toothed cats and gigantic hyenas. But did they ever have to take an organic chemistry final or host the in-laws for the holidays? Now that’s stress. And what we eat can either help our bodies fight stress– or hurt the effort.
In one of the biggest advances against leukemia and other blood cancers in many years, doctors are reporting unprecedented success by using gene therapy to transform patients' blood cells into soldiers that seek and destroy cancer.
While posttraumatic stress is expected after natural disasters, few survivors anticipate the positive psychological changes that they may experience – and now new research has revealed that genes may play a role.
