State health researchers have discovered the first new strain of botulism in four decades, but decided to withhold publishing the genetic code because of bioterrorism concerns.
Can an experimental drug developed to treat epilepsy block the AIDS virus? A preliminary lab study suggests it's possible, and researchers are eager to try it in people.
Health advocates cheered last month’s FDA proposal to ban partially hydrogenated oils— which contain trans fats that increase the risk of heart disease— but some wonder whether the substitutes for these fats will be any healthier.
Metabolism was lost in the shadows of cancer research for decades but has recently been reclaiming some of the spotlight. Now, research has shown that aerobic glycolysis is not the consequence of the cancerous activity of malignant cells but is itself a cancerous event.
A mosquito-borne virus that kills about half of the people it infects uses a never-before-documented mechanism to “hijack” one of the cellular regulatory systems of its hosts to suppress immunity, according to scientists.
Scientists have discovered that as the brain reorganizes connections throughout our life, the process begins earlier in girls which may explain why they mature faster during the teenage years.
A research team has found no evidence of an association between iron levels in the body and the risk of atherosclerosis, the hardening and narrowing of the arteries that leads to cardiovascular disease.
A new study shows that ALK and ROS1 gene rearrangements known to drive subsets of lung cancer are also present in some colorectal cancers.
Scientists have confirmed that variations in a particular gene play a key role in the autism spectrum condition known as Asperger Syndrome, and that variations in the same gene are also linked to differences in empathy levels.
Researchers have isolated a gene, DCC, which is responsible for dopamine connection in the medial prefrontal cortex during adolescence and established that dysfunction of this gene during adolescence leads to behavioral consequences in adulthood.
Prescribing an apple a day to all adults aged 50 and over would prevent or delay around 8,500 vascular deaths such as heart attacks and strokes every year in the UK, according to a new study.
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.
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.
