Widely used treatments for type 2 diabetes have different effects on the hearts of men and women, even as the drugs control blood sugar equally well in both sexes, according to new research.
A study in mice shows how a breakdown of the brain’s blood vessels may amplify or cause problems...
Poverty may have direct implications for important, early steps in the development of the brain...
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 way to analyze the genetic causes of cutaneous melanoma (CM), according to a new study.
A new finding by scientists has identified key steps that trigger the disintegration of cellular regulation that leads to cancer.
Two very different recent papers come to a similar conclusion: cyclical, physiologic hormone replacement therapy (HRT) aids memory in postmenopausal women. One paper found native progesterone, as it is in its natural state cycling the body, helps memory early post-menopause. The other paper found cyclic, physiologic, administered estrogen helps memory after induced menopause.
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.
A new study shows that bacteria exhibit different genetic variations that have helped them adapt in different ways, allowing then to create a surprising number of genetic paths to survival within each patient.
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.
A simple blood test will soon be able to catch the vast majority of a group of chronic blood cancers, a new study reveals. The scientists also identified a new gene, CALR, which is altered in 40 percent of blood disorders.
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.
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.
Scientists have devised the first method to measure the push and pull of cells as embryonic tissue develops. The cells’ tiny forces are measured in 3-D tissues and living embryos.
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.
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.
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.
