Should You Really Be Behind the Wheel After Concussion?

Even after all of their symptoms are gone, people who have had a concussion take longer to regain complex reaction times, the kind you need in most real-life driving situations on the road, according to a preliminary study released today that will be presented at the American Academy of Neurology's […]

Aging memories may not be ‘worse,’ just ‘different’

“Memory is the first thing to go.” Everyone has heard it, and decades of research studies seem to confirm it: While it may not always be the first sign of aging, some faculties, including memory, do get worse as people age. It may not be that straightforward. Zachariah Reagh, assistant […]

SFU chemist’s new process fast-tracks drug treatments for viral infections and cancer

Discovering antiviral and anticancer drugs will soon be faster and cheaper thanks to new research from SFU chemist Robert Britton and his international team. For the past 50 years, scientists have used manmade, synthetic, nucleoside analogues to create drug therapies for diseases that involve the cellular division and/or the viral […]

What Factors Help Predict Who Will Keep Their Memory into Their 90s?

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, […]

Blood test could predict who will benefit from immunotherapy, researchers find

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 […]

Precision Medicine Identifies Key Recurring Mutation in Head and Neck Cancer

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 […]

Inhibiting Enzyme Helps Cancer Immunotherapy Work Better

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 […]

Can Sleep Protect Us from Forgetting Old Memories?

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 […]

Implanted Neural Stem Cell Grafts Show Functionality in Spinal Cord Injuries

Using stem cells to restore lost functions due to spinal cord injury (SCI) has long been an ambition of scientists and doctors. Nearly 18,000 people in the United States suffer SCIs each year, with another 294,000 persons living with an SCI, usually involving some degree of permanent paralysis or diminished […]

Naked Mole-Rat Senescent Cells are Unusually Vulnerable to Oxidative Stress

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 […]

Long Term Low Dose Ethanol Intake Modestly Extends Life in Mice

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 […]

Monkeying around: Study finds older primates father far fewer babies

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. Older male rhesus monkeys sire fewer offspring, even though […]

Glucosamine Supplementation Correlates with Lower All Cause Mortality

An analysis of a large study population here shows that glucosamine supplementation results in about a 15% reduction in mortality, a sizable effect size in the context of what is known of the effects of lifestyle choices and supplementation on aging. Glucosamine is used as an anti-inflammatory intervention, but there […]

Hearing deterioration reported by discharged COVID-19 patients

A significant number of patients reported a deterioration in their hearing when questioned eight weeks after discharge from hospital admission for COVID-19, according to the University of Manchester audiologists, in a study supported by the NIHR Manchester Biomedical Research Centre (BRC). One hundred and twenty-one of the adults admitted to […]

How human sperm really swim: research challenges centuries-old assumption

More than three hundred years after Antonie van Leeuwenhoek used one of the earliest microscopes to describe human sperm as having a “tail, which, when swimming, lashes with a snakelike movement, like eels in water”, scientists have revealed this is an optical illusion. Using state-of-the-art 3D microscopy and mathematics, Dr Hermes […]

Why is stroke so deadly for people of African descent?

African-Americans have up to three times the risk of dying from strokes as people of European descent, yet there has been little investigation of if and how genetic variants contribute to their elevated risk. Until now. A large international team of scientists has completed the largest analysis of stroke-risk genes […]

Study Suggests New Approach to Improve Radiation Therapy Resistance in Glioblastoma

Many modern cancer drugs target a specific genetic mutation that is driving particular cancer’s runaway growth and division — such as the HER-2 protein in some breast cancers or EGFR in certain lung cancers. But this strategy hasn’t worked well against glioblastoma, an aggressive form of brain cancer, which is […]
