DECEMBER 3RD, 2020 CONN HASTINGS Researchers at Imperial College London have developed a tiny lab-on-a-chip that can perform PCR diagnostics in just a few minutes. Usually requiring bulky and expensive lab equipment, PCR is a gold standard diagnostic test for a variety of infectious pathogens, including bacteria and viruses, such as SARS-CoV-2. The new testing device...
Advances in technique and technology have made ultrasound increasingly valuable for imaging a wide variety of medical applications, including pulmonary disease. That’s remarkable, in part, because it was once thought that ultrasound, which most people associate with pregnant mothers and prenatal check-ups, would never be useful in assessing lung health. And it’s important because it can improve...

INSTITUTE FOR QUALITY AND EFFICIENCY IN HEALTH CARE For heavy (ex-)smokers, lung cancer screening using low-dose computed tomography (low-dose CT, LDCT) offers more benefit than harm: The procedure can save a number of people from dying of lung cancer; for some of them, it might also prolong overall survival. This is the conclusion drawn by...

MEMORIAL SLOAN KETTERING CANCER CENTER Treatments that harness the immune system to fight cancer have greatly improved outcomes for some people with cancer. Scientists are learning more about why some people respond much better than others to these drugs. One major factor is something called tumor mutation burden (TMB) — the number of DNA changes...
by University of California, San Francisco Credit: CC0 Public Domain Just a few doses of an experimental drug can reverse age-related declines in memory and mental flexibility in mice, according to a new study by UC San Francisco scientists. The drug, called ISRIB, has already been shown in laboratory studies to restore memory function months after...
