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.
Scientists have discovered a second code hiding within DNA. This second code contains information that changes how scientists read the instructions contained in DNA and interpret mutations to make sense of health and disease.
A study in mice shows how a breakdown of the brain’s blood vessels may amplify or cause problems associated with Alzheimer’s disease.
Poverty may have direct implications for important, early steps in the development of the brain, saddling children of low-income families with slower rates of growth in two key brain structures.
Exercise might help women beat breast cancer. Researchers found it can ease the achy joints and muscle pain that lead many patients to quit taking medicines that treat the disease and lower the risk of a recurrence.
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.
For decades, researchers have sought a biological toolset capable of precisely and systematically turning off genes throughout the genomes of human cells. The CRISPR-Cas9 system– a recently discovered system with bacterial origins– has the potential to overcome many of the limitations of currently available gene-silencing techniques.
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.
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.
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.
