Researchers at McMaster University and the Royal Ontario Museum (ROM) have reported  the discovery and diagnosis of an aggressive malignant bone cancer — an osteosarcoma — for the first time ever in a dinosaur. No malignant cancers—tumours that can spread throughout the body and have severe health implications—have ever been […]

Why do some people stay sharp into their 90s, even if they have the amyloid plaques in the brain that are associated with Alzheimer’s disease? And why do others reach their 90s without ever developing any plaques? These questions are explored in a new study published in the July 22, […]

A test that detects changing levels of tumour fragments in the blood may be an easy, non-invasive and quick way to predict who will benefit from immunotherapy, University of Toronto researchers say. Immunotherapy can shrink tumours and prolong survival for patients for whom other treatments have failed. But it only helps […]

A new type of immunotherapy for the skin cancer malignant melanoma shows promising results. Three severely ill patients are now long-term survivors. The study, published in OncoImmunology, is the result of a collaboration between researchers at Karolinska Institutet and Karolinska University Hospital. “Immunotherapy is based on activation of the body's […]

Aging is just not fun. At the later stages of your life you are more likely to encounter some serious health problems, such as Alzheimer’s disease. Once you hear this diagnosis, you know you’re in for a bad ending, because it is incurable. However, now scientists at the University of […]

Head and neck cancer is one of the leading causes of cancer-related deaths worldwide, and squamous cell carcinomas (HNSCC) account for the majority of these cases. In a new study, based on preclinical research and published in Molecular Cancer Therapeutics, a journal of the American Association for Cancer Research, researchers […]

Cancer immunotherapy — a treatment that better enables a patient’s own immune system to attack tumors — has shown great potential against some cancers. Yet immunotherapy doesn’t work against all tumor types, and many patients who initially respond later develop resistance and relapse. Researchers at University of California San Diego […]

From lowering your risk of obesity and cardiovascular disease to improving your concentration and overall daily performance, sleep has been proven to play a critical role in our health. In a new study, researchers at University of California San Diego School of Medicine report that sleep may also help people […]

Using stem cells to restore lost functions due to spinal cord injury (SCI) has long been an ambition of scientists and doctors.

This open access paper expands on earlier work on cellular senescence in long-lived naked mole-rats. Individuals of this species can live as much as nine times longer than equivalently sized rodents, and are near immune to cancer. In other mammals, senescent cells accumulate with age and disrupt tissue function via […]

As of the past few years, the long-standing debate over whether moderate alcohol intake has a protective effect on health had appeared to resolve to the conclusion that the observed epidemiology is explained by socioeconomic factors, not by the metabolic effects of molecules such as polyphenols present in wine or […]

Infertility is a worldwide clinical problem for human health that affects 8 to 12 percent of couples. A new study from Washington University in St. Louis has implications for understanding some age-related aspects of male reproductive health in primates, including humans.
