“The pancreas,” says Gary Lewis, an endocrinologist at Toronto General Hospital and director of the Banting & Best Diabetes Centre at the University of Toronto’s Temerty Faculty of Medicine, “is like an exquisitely sensitive and perfectly networked computer.” Second by second, he notes, the pancreas secretes just the right amount of […]

A good way to find out what a cell is doing—whether it is growing out of control as in cancers, or is under the control of an invading virus, or is simply going about the routine business of a healthy cell—is to look at its gene expression. Though a vast […]

Children hospitalized with breathing problems due to a common viral lung infection are likely to get sicker and remain hospitalized if they have high levels of defective copies of the virus, according to a new study by researchers at Washington University School of Medicine in St. Louis. The findings, published […]

If you could stay forever young, you would probably use that opportunity. Scientists say that aging is actually a disease and should be dealt with as such. Researchers from the University of Waterloo found that there is a best time of day to take anti-aging supplements and it actually depends […]

COVID-19 stays with you even after the negative diagnosis. Some symptoms are long-lasting and can significantly alter one’s quality of life. Scientists are researching this phenomenon, called long COVID, and found that it is more common in women under 50 and people who experienced severe disease. Furthermore, this research led […]

The humble lab mouse has provided invaluable clues to understanding diseases ranging from cancer to diabetes to COVID-19. But when it comes to psychiatric conditions, the lab mouse has been sidelined, its rodent mind considered too different from that of humans to provide much insight into mental illness. A new […]

Scientists are struggling with public misconceptions on what embryoids are and what research on them entails, the confusion that leads to policy decisions restricting access to important scientific exploration, according to a new paper by experts at Rice University — who blame the use of terms like synthetic or artificial […]

A couple of years ago, Joseph Shrager, MD, professor of cardiothoracic surgery at Stanford School of Medicine, noticed a statistical anomaly in his practice. It seemed that patients were diagnosed with lung cancer at a surprisingly higher rate at 65 years old than, say, at 64 or 66. “There were no reason […]

A new analysis of the entire genetic makeup of more than 53,000 people offers a bonanza of valuable insights into heart, lung, blood and sleep disorders, paving the way for new and better ways to treat and prevent some of the most common causes of disability and death. The analysis […]

A team of researchers at the University of Alberta has uncovered a long-sought link in the battle to control cholesterol and heart disease. The protein that interferes with low-density lipoprotein (LDL) receptors that clear “bad” cholesterol from the blood was identified in findings recently published in Nature Communications by Dawei Zhang, associate professor of pediatrics […]

Over evolutionary time scales, a single gene may acquire different roles in diverging species. However, revealing the multiple hidden roles of a gene was not possible before genome editing came along. Cold Spring Harbor Laboratory scientists Zach Lippman and Anat Hendelman collaborated with Idan Efroni of Hebrew University in Israel to reveal […]

COVID-19 vaccine is what will pull us out of this pandemic. However, some people are not sure about the timing. If you are waiting for an elective surgery, should you get a vaccine shot before the procedure? Or should you wait and get the jab after the surgery? Scientists at […]
