Damage to the brain's outer layer caused by smoking may be reversible after quitting, but it could take years, a study said. Brain scans of 500 Scottish septuagenarians confirmed a link between smoking and an acceleration of age-related thinning of the cortex—the outer layer of grey matter, researchers reported.
Scientists at The Scripps Research Institute (TSRI) have identified a new cellular pathway that is affected in cystinosis, a rare genetic disorder that can result in eye and kidney damage.
The researchers, from Cancer Research UK's Health Behaviour Research Centre at University College London (UCL), interviewed almost 1,900 people aged 50-80 years old about their views on cancer screening.
A vial of rare snake venom refused to give up its secret formula for lethality; its toxins had no effect on the proteins that most venoms target.
Firsthand experience working in hospitals and clinics helped inspire third-year Stanford medical student Pelu Tran to explore a potential career path in the world of high-tech startups.
Ebola has claimed nearly 9,000 lives in West Africa over the past year, although new infections have dropped dramatically in recent months.
President Barack Obama's nominee to serve as U.S. drug "czar" won unanimous approval in the Senate Monday as lawmakers vowed to curb an epidemic that results in more than 40,000 deaths a year from overdoses of prescription painkillers, heroin and other substances.
Researchers have revealed how damage from obesity is passed from a mother to her children, and also how that damage can be reversed.
After the highly charged Super Bowl, two sobering studies emerged. One unveiled an improved molecular imaging technology that verified—and precisely identified—brain damage in some National Football League (NFL) players. The other study revealed that brain damage can be more severe in NFL players who start playing football before age 12.
Scientists have developed a potential new therapy based on an unlikely model: immune molecules from cows.
A new Dartmouth College study sheds light on the brain cells that function in establishing one's location and direction. The findings contribute to our understanding of the neural mechanisms underlying our abilities to successfully navigate our environment, which may be crucial to dealing with brain damage due to trauma or a stroke and the onset of diseases such as Alzheimer's.
Have you ever wondered why it’s so tough to put down that last slice of bacon? Part of the answer is that humans are evolutionarily programmed to crave fatty foods, which offer the biggest bang for the buck, nutritionally speaking, with more than twice the calorie density of protein- or starch-rich food.
SuperAgers, aged 80 and above, have distinctly different looking brains than those of normal older people, according to new Northwestern Medicine research that is beginning to reveal why the memories of these cognitively elite elders don’t suffer the usual ravages of time.
In the 1980s, immunotherapy researcher Lieping Chen, M.D., Ph.D., embraced the career goal of curing one cancer. That lofty-seeming goal is beginning to look more modest today. Recent clinical trials have shown that one cancer after another is vulnerable to immune modulation therapy, a cancer-fighting strategy Chen pioneered that for years was considered marginal.
In 2008, the World Health Organization announced a global effort to eradicate malaria, which kills about 800,000 people every year. As part of that goal, scientists are trying to develop new drugs that target the malaria parasite during the stage when it infects the human liver, which is crucial because some strains of malaria can lie dormant in the liver for several years before flaring up.
Since December, more than 100 people in 14 states have been infected with measles in an outbreak traced to Disneyland, Melissa Stockwell, MD, MPH, assistant professor of pediatrics and of population & family health, has spoken out to debunk seven myths about the measles vaccine.
The largest U.S. measles outbreak in recent history isn't the one that started in December at Disneyland. It happened months earlier in Ohio's Amish country, where 383 people fell ill after unvaccinated Amish missionaries traveled to the Philippines and returned with the virus.
The drop-off in Ebola infections is good news for Liberia, but it means there are not enough sick people to take part in the study.
Federal health officials faced tough questions from lawmakers Tuesday about why they didn't take steps to produce a better flu vaccine as it became clear that this year's version wasn't going to offer much protection.
A preliminary study suggests stem cell transplantation may reverse disability and improve quality of life for patients with relapsing-remitting multiple sclerosis.
Humans have fewer remnants of viral DNA in their genes compared to other mammals.
Using the same technology that made smartphone cameras possible, scientists at Columbia University Medical Center are capturing images of individual molecules at a level of detail never before possible—including images of a molecule implicated in heart disease and muscle diseases.
By scanning the brains of people engaged in selective attention to sensations, researchers have learned how the brain appears to coordinate the response needed to ignore distractors. They are now studying whether that ability can be harnessed, for instance to suppress pain.
Bottles of Walmart-brand echinacea, an herb said to ward off colds, were found to contain no echinacea at all. GNC-brand bottles of St. John's wort, touted as a cure for depression, held rice, garlic and a tropical houseplant, but not a trace of the herb.
Despite improvements in the past few decades with surgery, chemotherapy and radiation therapy, a predictably curative treatment for glioma does not yet exist. New insights into specific gene mutations that arise in this often deadly form of brain cancer have pointed to the potential of gene therapy, but it’s very difficult to effectively deliver toxic or missing genes to cancer cells in the brain.
