Many older adults with high blood pressure can be treated less aggressively, which could mean taking fewer pills to get it under control, according to new treatment guidelines from an expert panel.
Chinese authorities said Wednesday that a 73-year-old Chinese woman died after being infected with a bird flu strain that had sickened a human for the first time, a development that the World Health Organization called "worrisome."
Researchers have discovered a tube-shaped structure that forms temporarily in a certain type of virus to deliver its DNA during the infection process and then dissolves after its job is completed.
For some cancer patients, the mental fogginess that develops with chemotherapy lingers long after treatment ends. Now, research in breast cancer patients may offer an explanation.
In a new study researchers have found a way of reducing ALS disease toxicity, which slows the dysfunction of neurons and shows that a parallel mechanism can reduce toxicity in mammalian cells.
A controversial oil and natural gas drilling technique called hydraulic fracturing, or fracking, uses many chemicals that can disrupt the body’s hormones, according to new research.
Teens who were heavy marijuana users- smoking it daily for about three years- had abnormal changes in their brain structures related to working memory and performed poorly on memory tasks, according to a new study.
There's more disappointing news about multivitamins: Two major studies found popping the pills didn't protect aging men's brains or help heart attack survivors.
New collaborative work is easing the distinction between which strands of RNA are worthy of scientific inquiry by combining computational and experimental approaches to identifying biologically meaningful RNA folds.
A protein in Salmonella inactivates mast cells- critical players in the body’s fight against bacteria and other pathogens- rendering them unable to protect against bacterial spread in the body, according to researchers.
Scientists have discovered a key process during the invasion of the blood cell by the Malaria parasite, and more importantly, found a way to block this invasion.
Researchers have made a major leap forward in treating renal disease, announcing they have grown a kidney using stem cells. The breakthrough paves the way for improved treatments for patients with kidney disease and bodes well for the future of the wider field of bioengineering organs.
The federal government said Monday it has no evidence that antibacterial chemicals used in liquid soaps and washes help prevent the spread of germs, and it is reviewing research suggesting they may pose health risks.
Thousands of years ago, a population of Astyanax mexicanus fish in northeastern Mexico swam or was swept from its hospitable river home into harsh underwater caves and became trapped. Facing a dramatically different environment of near total darkness and hardly any food, the fish had to adapt— fast.
A novel way to speed the testing of cancer drugs and quickly separate winners from duds has yielded its first big result: an experimental medicine that shows promise against a hard-to-treat form of breast cancer.
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.
