The human immune system is a thing of wonder. Up until now it had been widely assumed that the ability of killer T cells to destroy tumor cells and pathogens would deteriorate with age. It turns out, however, that the opposite is true—they become better killers, the older they get. This surprising finding is the […]

My most recent research focuses on a group of people who exemplify the idea of being “relentless.” Journalists are known for their relentless pursuit of truth so citizens know what their governments, businesses, schools and leaders are doing. My focus has been on journalists who have covered mass shootings. We hear about these tragedies too […]

Forms of dementia could be spotted sooner and more easily by analyzing recordings of patients’ electrical brain activity using artificial intelligence (AI), according to new research. Scientists from the University of Surrey and the University of Newcastle have shown that it is possible to use electroencephalography (EEG) as a low-cost diagnostic tool to help clinicians […]

In many countries there has been an explosion in the number of people undertaking cold water immersion (CWI) for anecdotally claimed mental and physical benefits, from home-based ice baths and cold showers, to open water swims and dips. The BBC One series Freeze The Fear, actively promoted CWI to improve the natural recovery process of […]

Good sleep and circadian health are interdependent and can impact our physical and mental well-being. But, around 62% of adults worldwide say they don’t sleep well. And more than 40% say their sleep has gotten worse in the past five years. Environmental factors are one cause behind these sleep and circadian rhythm disturbances. Matt Jones, […]

Many drug-resistant tumors have dysfunctional metabolism of ceramide, a metabolite that promotes cell death. Investigators who previously demonstrated that augmenting ceramide can counter tumors’ drug resistance mechanisms have now shown that adding ceramide nanoliposomes can improve the efficacy of a standard chemotherapy regimen of venetoclax plus cytarabine in models of acute myeloid leukemia. In their […]

Scientists at St. Jude Children’s Research Hospital have discovered which cells give rise to certain high-risk groups of medulloblastoma. The findings will help researchers better understand the biology of the disease, as well as develop better research models and guide their hunt for therapeutic targets. The findings were published today in Nature. Medulloblastoma is the […]
