Small glands are located at base of the skull, meaning they had gone undetected. Their discovery could have serious implications for radiation therapy...

For the thousands of Canadians at risk of blindness, eight-year-old Sam is a beacon of hope. He is the first Canadian to be treated with gene replacement therapy for a rare form of blindness which had left Sam unable to see sky on a cloudy day, and unable to make out shapes in the dark.

In the largest clinical trial of its kind, researchers show that combining sound and electrical stimulation of the tongue can significantly reduce tinnitus, commonly described as “ringing in the ears.” They also found that therapeutic effects can be sustained for up to 12 months post-treatment. The findings could potentially help millions of people since tinnitus affects about 10 to 15 percent of the population worldwide.

The so-called love hormone, oxytocin, may be worth investigating as a treatment for COVID-19, a new study suggests. One of the most serious complications of infection with the new coronavirus is a "cytokine storm," in which the body attacks its own tissues.

What we are only now beginning to understand is that the diseases that ultimately kill us are inseparable from the aging process itself. Aging is the root cause. This means that studying these diseases without taking aging into account could be dangerously misleading… and worst of all, impede real progress.

What happens when there are two competing definitions of death, confounding our understanding of the end of life? On 9 December 2013, Jahi McMath, a 13-year-old African-American girl living in Oakland, California, entered the hospital for a tonsillectomy, still one of the most common surgical procedures performed on children and often recommended for sleep apnoea, a condition she had been living with.

A druggable pocket in the SARS-CoV-2 Spike protein that could be used to stop the virus from infecting human cells has been discovered by an international team of scientists led by the University of Bristol. The researchers say their findings, published today [21 September] in the journal Science, are a potential 'game changer' in defeating the current pandemic and add that small molecule anti-viral drugs developed to target the pocket they discovered could help eliminate COVID-19.

The recognized pioneers of controversial gene-editing tool "Crispr-Cas9" are recently awarded by this year's Nobel Prize in Chemistry. Scientists Emmanuelle Charpentier and Jennifer Doudna are two women researchers that are recently added to the list of Nobel Prize winners of the world. This tool has been controversial due to its past issues of allegedly altering the genes of two unborn twins in China to stop them from acquiring AIDS.

For 32-year-old Hanna Lockman of Louisville, Kentucky, it all started March 12. She was at work when she suddenly felt a stabbing pain in her chest. “It just got worse and worse and worse, to the point I was crying from the pain,” she recalled in a recent interview. At 3 am, the pain sent her to the emergency department. “I had developed a dry cough, maybe a mild fever. I don’t remember.”

Face masks have become an important tool in fighting against the COVID-19 pandemic. However, improper use or disposal of masks may lead to "secondary transmission". A research team from City University of Hong Kong (CityU) has successfully produced graphene masks with an anti-bacterial efficiency of 80%, which can be enhanced to almost 100% with exposure to sunlight for around 10 minutes. Initial tests also showed very promising results in the deactivation of two species of coronaviruses. The graphene masks are easily produced at low cost, and can help to resolve the problems of sourcing raw materials and disposing of non-biodegradable masks.

University of Pittsburgh School of Medicine scientists have isolated the smallest biological molecule to date that completely and specifically neutralizes the SARS-CoV-2 virus, which is the cause of COVID-19. This antibody component, which is 10 times smaller than a full-sized antibody, has been used to construct a drug—known as Ab8—for potential use as a therapeutic and prophylactic against SARS-CoV-2.

Among the million or so lives lost to COVID-19 there are stories that defy understanding. Healthy bodies, young and in their prime, succumb to the virus as easily as if they were among the most vulnerable. While for others in their age group, the vir

The Trump administration has notably opposed medical research that uses fetal tissue from abortions, while knocking back numerous requests from scientists to work with it.

Biostasis, or "suspended animation," is a hibernation-like technique that researchers and doctors believe could help save many lives in the future. Indeed, at present, there are already short or partial techniques that have an almost automatic and natural reversibility.

Some rare people may purge most HIV from their bodies, leaving only broken copies of the virus or copies locked in molecular prisons, from which there is no escape.

The independent Africa Regional Certification Commission (ARCC) for Polio Eradication yesterday officially declared the World Health Organization (WHO) African Region is free of wild polio virus. This significant declaration is working toward the goal of the world’s eradication of polio. In fact 5 out of 6 World Health Organization regions are now wild polio-free. When this last region declares it is wild polio-free, it will be the second virus eradicated from the world, since smallpox was given that declaration in May 1980.

Venom from honeybees is found to rapidly kill aggressive and hard-to-treat breast cancer cells, according to potentially ground-breaking new Australian research, with hopes the discovery will lead to the development of a treatment for triple-negative breast cancer. The study also found when the venom's main component was combined with existing chemotherapy drugs, it was extremely efficient at reducing tumour growth in mice.

When you visit your doctor, you might assume that the treatment they prescribe has solid evidence to back it up. But you'd be wrong. Only one in ten medical treatments are supported by high-quality evidence, our latest research shows.

Acetaminophen, one of the most consumed drugs in the US – and the most commonly taken analgesic worldwide – could be doing a lot more than simply taking the edge off your headache, new evidence suggests.

Amid growing concerns that a bout of COVID-19 might damage the heart, a small study is reporting signs of an inflammatory heart condition in college athletes who had the infection. More than two dozen male and female competitive athletes at Ohio State University underwent magnetic resonance imaging of their hearts in the weeks to months after a positive test for SARS-CoV-2, the virus that causes COVID-19.
