It has long been known that there are many physical and mental health benefits of breastfeeding for mothers and babies. But can these benefits be due to genetic changes induced by breastfeeding? New research suggests that connection. The research, published in the edition of Pediatrics, was led by Barry M. Lester, Ph.D, […]

A team of Canadian scientists, including researchers at the Montreal Neurological Institute and Hospital (The Neuro) has discovered the first French-Canadian founder mutation gene linked to synucleinopathies, a group of neurodegenerative diseases that includes Parkinson’s disease (PD), dementia with Lewy-Bodies (DLB) and multiple system atrophy (MSA). The mutation, known as […]

An apple a day keeps the doctor away. That is how that old saying goes, but some people substitute apple with a pill of aspirin. This quite strange yet very common behaviour was encouraged by doctors and older people alike. It is believed that taking a low daily dose of […]

Researchers at the Abramson Cancer Center tested a new immunotherapy approach utilizing a therapeutic vaccine in two groups of patients with advanced head and neck squamous cell carcinoma (HNSCCa), and found 86 percent showed elevated T cell activity. It is the first study to show that the vaccine can help immune cells infiltrate tumors. HNSCCa […]

Delivery of corticosteroids directly into the eye is more effective than injections adjacent to the eye, according to results from a comparative clinical trial of macular edema in patients with noninfectious uveitis. The study was funded by the National Eye Institute (NEI), part of the National Institutes of Health. The […]

Sometimes our cells employ meticulous and elegant solutions to fix things that break. Other times, they slap on some duct tape and keep going. The human body can apply these quick-and-dirty methods to even its most critical components, such as when both strands of a DNA helix suddenly snap. Such […]

Some babies act like they are in a rush. They come to this world too quickly and have to deal with some health problems because of it. Scientists know this issue, which is why they are looking for ways to aid the brain development of pre-term babies. However, nature already […]

Pretty much everyone knows that drinking has severe negative health effects – that is not a surprise to anyone. However, some people are still abusing alcohol, while completely ignoring all the warning signs. A new study from the University of Adelaide found that middle-age drinkers who only consume a moderate […]
