For the first time, University of Utah Health scientists have shown that artificial intelligence could lead to better ways to predict the onset and course of cardiovascular disease. The researchers, working in conjunction with physicians from Intermountain Primary Children’s Hospital, developed unique computational tools to precisely measure the synergistic effects of existing medical conditions on the heart and blood vessels. […]

Scientists at the University of Bristol have developed new biological parts that are able to shape the flow of cellular processes along DNA. The work, now published in the journal Nature Communications, offers a fresh perspective on how information is encoded in DNA and new tools for building sustainable biotechnologies. Despite being invisible to the naked eye, microorganisms are integral […]

Editor’s note: Find the latest COVID-19 news and guidance in Medscape’s Coronavirus Resource Center. Most people experience COVID fatigue a few times a week, but men and women and older and younger people have reacted differently to it, a recent WebMD poll suggests. The poll, taken from December 23-January 4, asked readers how often they had experienced COVID-19 pandemic fatigue, […]

In a recent study published on the medRxiv* preprint server, researchers examine the effects of previous severe acute respiratory coronavirus-2 (SARS-CoV-2) infections on the immunity offered by SARS-CoV-2 vaccination. Study: Imprinted SARS-CoV-2-Specific Memory Lymphocytes Define Hybrid Immunity.

Editor’s note: Find the latest COVID-19 news and guidance in Medscape’s Coronavirus Resource Center. A new study from California and New York found that people who were both vaccinated and had a prior COVID-19 infection had the most protection against the coronavirus last summer and fall. Unvaccinated people with a past infection came in second. By October, when the more […]

When our muscles become acidic after doing too many press-ups, squats or cycling to work, it is because of lactic acid. Strained muscles produce energy fast, and a by-product of that process is lactic acid. However, lactic acid is also abundant in cancer cells, which invest a lot of energy into dividing and forming tumors. Now a new study from […]

The study covered in this summary was published on medRxiv.org as a preprint and has not yet been peer reviewed.  Key Takeaways Intermittent caloric restriction is associated with reduced memory T cell subsets in people with multiple sclerosis (MS). Changes in circulating levels of lipid metabolites, such as acyl carnitines and specific glycerophospholipids, may mediate the changes in specific T […]

Some patients with rheumatic heart disease who are thought to have an allergic response to injectable penicillin may actually be experiencing a cardiac reaction to the injection, new information suggests. This has resulted in new advice from the American Heart Association (AHA) suggesting that oral penicillin may be a safer option for people with rheumatic heart disease who are at […]

‘Brain fog’ caused by Covid could be a result of how the virus affects a person’s spinal fluid, study finds  ‘Brain fog’, where a person suffers memory and cognitive issues, as a result of Covid may be tied to how the virus affects a person’s spinal fluid Researchers found antibodies and increased protein levels in the fluid, indicating inflammation as […]
