by Massachusetts General Hospital Results from a recent clinical trial indicate that for older adults with advanced cancer, initiating aspirin may increase their risk of disease progression and early death. The study, which was conducted by a binational team led by researchers at Massachusetts General Hospital (MGH), the Berman Center in Minnesota, and Monash University...
by Brandie Jefferson, Washington University in St. Louis “Older adults might be representing events in different ways, and transitions might be picked up differently than, say, a 20-year-old,” said Zachariah Reagh, assistant professor of psychological and brain sciences in Arts & Sciences. Reagh looked at fMRI images to study memory differences in different age groups....
by University College London A single dose of cannabidiol (CBD) helped increase blood flow to the hippocampus, an important area of the brain associated with memory and emotion, finds a new study led by UCL researchers. Researchers say the findings could be an important discovery for conditions which affect memory, such as Alzheimer’s disease and...

The spike protein (foreground) enables the virus to enter and infect human cells. On the virus model, the virus surface (blue) is covered with spike proteins (red)...
by James Cook University A study of older mice with type 2 diabetes has yielded highly promising results for researchers investigating potential new vaccines for tuberculosis (TB). A team of researchers from Australia, Bangladesh and France investigated a potential vaccine, BCG::RD1, and found it highly protective when administered directly into the lungs of diabetic mice,...
Therapeutic manipulations of these cells hold promise for promoting muscle injury repair and improving outcomes for individuals with muscular dystrophy (Boston)– Although macrophages (cells involved in the detection and destruction of bacteria and other harmful organisms as well as dead cells) are classified as immune cells functioning in the activation and resolution of tissue inflammation,...
by The Wistar Institute According to a study by The Wistar Institute, breast cancer cells starved for oxygen send out messages that induce oncogenic changes in surrounding normal epithelial cells. These messages are packaged into particles called extracellular vesicles (EVs) and reprogram mitochondrial shape and position within the recipient normal cells to ultimately promote deregulated...
By Sally Robertson, B.Sc. Researchers at Ligandal Inc., the University of California San Francisco and Toyota Technological Institute at Chicago, have designed novel synthetic peptides that potently inhibit the ability of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to infect host cells. The team’s SARS-BLOCK™ peptides competitively inhibit the receptor-binding domain (RBD) on the SARS-CoV-2...
Boosting the immune system could offer a potential treatment strategy for COVID-19, according to a new study. As the COVID-19 pandemic continues to claim lives around the world, much research has focused on the immune system’s role in patients who become seriously ill. A popular theory has it that the immune system gets so revved...
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 Toronto and the Sunnybrook Research...
