Charcot Marie Tooth and Dejerine-Sottas syndrome are groups of diseases that involve the breakdown of the myelin sheath covering nerve axons. As this myelin sheath breaks down, people who have these disorders suffer nerve damage in the arms and legs—those with Dejerine-Sottas disease may never walk or may lose the […]

A high daily dose of an omega-3 supplement may help slow the effects of ageing by suppressing damage and boosting protection at the cellular level during and after a stressful event, new research suggests. Researchers at Ohio State University found that daily supplements that contained 2.5 grams of omega-3 polyunsaturated […]

The decline of the immune system is of great importance in aging. Vulnerability to infection, a decreased surveillance of senescent cells and cancerous cells, and growing chronic inflammation all take their toll. A sizable fraction of this problem stems from the diminished supply of new T cells of the adaptive […]

NASA’s SpaceX Crew-2 mission is set to launch four astronauts to the International Space Station aboard a SpaceX Crew Dragon on Earth Day, April 22. The four include NASA astronauts Shane Kimbrough and Megan McArthur and, a first for the Commercial Crew Program, two international partners, Japan Aerospace Exploration Agency (JAXA) astronaut Akihiko Hoshide and […]

Cancer cells can dodge chemotherapy by entering a state that bears similarity to certain kinds of senescence, a type of “active hibernation” that enables them to weather the stress induced by aggressive treatments aimed at destroying them, according to a new study by scientists at Weill Cornell Medicine. These findings […]

Excess sugar in the blood, the central feature of diabetes, can react with immune proteins to cause myriad changes in the immune system, including inflammatory changes that promote atherosclerosis, according to a new study from scientists at Weill Cornell Medicine and University of Massachusetts Medical School. The study, published in […]

Radiation therapy appears to increase the expression of genes with mutations that induce an immune response to malignant cells, according to preclinical research by Weill Cornell Medicine and NewYork-Presbyterian investigators. The findings suggest that radiation treatment directed to tumors in mice may help to improve a form of immunotherapy that […]

Next time you reward a child with a treat, consider offering fruit, nuts or a cereal bar instead of ice cream or candy, a Cornell economist suggests. Research by an international team including Michèle Belot, professor in the Department of Economics, found that children valued a sweet food more after receiving […]

Supplementation of cocoa powder in the diet of high-fat-fed mice with liver disease markedly reduced the severity of their condition, according to a new study by Penn State researchers, who suggest the results have implications for people. Cocoa powder, a popular food ingredient most commonly used in the production of […]

In the journal “Nature Communications”, scientists of the German Center for Neurodegenerative Diseases (DZNE) report new findings on the mechanisms of “Niemann-Pick type C disease” (NPC). This rare brain disorder mainly manifests in childhood and includes severe neurological and psychiatric symptoms. Researchers led by Dr. Sabina Tahirovic have now found […]

More than 20 years after the launch of a landmark clinical trial, follow-up examinations and analyses found that not all patients with elevated eye pressure need pressure-lowering treatment to prevent vision loss from glaucoma. When the study was launched, it was universally accepted that all patients with elevated eye pressure […]

A new study investigates a genetic culprit behind abdominal aortic aneurysm, a serious condition that puts people at risk of their aorta rupturing – a potentially deadly event. Finding a viable genetic target for AAA could change the game, says senior author Katherine Gallagher, M.D., a vascular surgeon and an associate professor of […]

More than half of cervical cancer cases in the United States occur in women who have not had timely Pap smears and/or HPV tests — screenings that allow for detection of precancerous or cancerous cells on the cervix. Encouraging low-income women, in particular, to participate in such screenings likely would […]

A new study from Cold Spring Harbor Laboratory (CSHL) Research Investigator Katharina Schmack and Adjunct Professor Adam Kepecs uncovered how hallucinations are produced in human and mouse brains. Their new mouse model for hallucination-like behaviours should help uncover mechanisms and treatments for schizophrenia. Schmack was working as a psychiatrist at the Charité–Universitätsmedizin Berlin […]

For a while now, heart disease researchers have known that a protein called GRK5 – expressed throughout the body, though most notably in the lungs, heart, and placenta – normally dwells in the outer membrane of heart cells and, upon exposure to stress, moves into the cell nucleus, switching on […]

The results of this epidemiological study suggest that suffering from untreated sleep apnea can raise the risk of later dementia and mild cognitive impairment by 20-30%. How the repeated hypoxia in the brain produced by sleep apnea results in a raised risk of dementia isn't understood in detail, but it […]

Researchers at the University of Alberta are looking for ways to prevent or slow cachexia, a muscle-wasting syndrome thought to cause up to a third of the 80,000 deaths related to cancer every year in Canada. By understanding the role of activin A, a growth factor that contributes to muscle […]

Scientists have figured out how to modify CRISPR’s basic architecture to extend its reach beyond the genome and into what’s known as the epigenome – proteins and small molecules that latch onto DNA and control when and where genes are switched on or off. In a paper published in the […]

Research from the University of Wisconsin–Madison finds that a new therapeutic approach for heart failure could help restore cardiac function by regenerating heart muscle. In a study recently published in the journal Circulation, the UW team describes its success in improving, in a mouse model, the function of heart muscle by […]

At its most basic level, it takes pictures. For UW–Madison biochemistry professor Elizabeth Wright, that’s the scaled-down explanation of cryogenic electron microscopy or cryo-EM. But it’s so much more than that. Through rapid freezing, controlled beams, and advanced lenses, this game-changing research tool reveals the intricate architecture of cells, viruses, and […]

Researchers at the DZNE (Germany), at Massachusetts General Hospital (USA) and at the genomic medicine company Sangamo Therapeutics, Inc. tested a novel gene regulation approach to treat brain diseases such as Alzheimer's in laboratory studies. It leverages zinc finger proteins, which specifically bind to the DNA that codes for the […]

McMaster University researchers have discovered a new treatment that could bring relief to millions of people worldwide living with peanut allergy. The current understanding is that in certain individuals, the immune system mistakenly identifies a specific food protein as harmful and triggers the production of an antibody called Immunoglobulin E […]

Despite surgery and subsequent treatment with chemotherapy and radiation, the majority of patients experience recurrence of malignant brain tumours. Researchers at Linköping University, Sweden, and the Medical University of Graz, Austria, have shown in cells in culture that an ion pump can deliver drugs more accurately, which gives less severe […]

A global study led by Hamilton scientists has found a link between eating processed meat and a higher risk of cardiovascular disease. The same study did not find the same link with unprocessed red meat or poultry. The information comes from the diets and health outcomes of 134,297 people from […]

Potentially game-changing research led by McMaster University scientists may finally bring relief to millions of people worldwide living with Crohn’s disease.
