Antibodies against the Epstein-Barr virus indicate risk of multiple sclerosis Biomarker discovered: A new blood test can detect the risk of developing multiple sclerosis (MS) years before the first symptoms appear. The test measures the level of antibodies that bind both the body's own structures and the Epstein-Barr virus, which serve as indicators of MS. This could lead to earlier diagnosis and treatment in the future, delaying or preventing the onset of the neurodegenerati

Surgical robots can also perform complex tasks autonomously Learning AI surgeon: A newly developed surgical robot can surgically remove a gallbladder without the assistance of human surgeons. The AI ​​system learned this through videos of operations and targeted feedback during practice surgeries. This allowed the robot surgeon to develop its skills similar to that of a young doctor. The innovative surgical robot can now operate independently and reacts confidently even to un

Trends and advances in cancer medicine Colon cancer is one of the most common and deadly cancers. Thanks to improved screening, the number of affected individuals has been declining for years, but the incidence of colon cancer is increasing at an alarming rate, especially among younger people. The reason for this is not yet fully understood, but there is increasing evidence that our modern lifestyle is to blame. But what factors specifically influence whether we develop colon

Special Microbes in the Gut Flora Improve Fiber Degradation in the Gut Mystery Solved? Previously little-noticed microbes in our gut could explain why some people are better "food converters" than others. An experiment reveals that certain archaea help the rest of the gut flora to break down fiber more efficiently and completely. As a result, the food provides the hosts of these microbes with more energy and calories. A hallmark of such "super-utilizers" in the gut is increas

First steps in metastasis formation clarified Quick-change artists: When melanoma cancer cells are attacked by the immune system, they activate specific genes and change their cell type. This reaction then inhibits T cells, among other things, making it easier for the skin cancer cells to colonize lymph nodes and form metastases, as researchers report in "Nature Cancer." They also identified proteins characteristic of these metastasis founder cells that may be suitable target

Gene Activity on the X and Y Chromosomes Influences Height XY becomes taller than XX: Researchers have discovered that a specific gene on the X and Y chromosomes plays an important role in our height. According to the study, this gene is more active on the male Y chromosome than on the second X chromosome in women. This gives men additional height. However, height is also influenced by other factors, including hormones and chromosome number. The method could also be used in t

Three-Part Antitoxin Neutralizes Toxins of the Deadliest Snakes Potent antidote: For the first time, physicians have developed a broadly effective antiserum against 19 deadly snake species – including mambas, cobras, taipans, and kraits. The new antitoxin neutralizes the neurotoxins of all venomous snakes, as mouse experiments suggest. The antitoxin was created from antibodies from a man who had immunized himself against snake venom hundreds of times. The antibody cocktail co

Great apes share alcoholic fruit with their peers Drinking binges in the animal kingdom: Chimpanzees may have alcoholic "parties" similar to humans – and thus strengthen the sense of community within the group, biologists have discovered. They observed the great apes in the wild several times communally consuming fermented breadfruit. Chimpanzees rarely share their food. The celebratory mood of humans and apes could, in this case, be traced back to a common ancestor, the team

Archaea Could Play a Previously Underestimated Role in the Microbiome A new roommate: Scientists have discovered a previously unknown microbe in our gut. It's not a bacterium, but a species of archaea. The species, dubbed Methanobrevibacter intestini, produces the gas methane – similar to a newly discovered variant of the archaea species Methanobrevibacter smithii. These findings suggest that our intestinal flora is significantly more influenced by archaea than previously tho

Antibody drug against Alzheimer's now also available in Europe How Lecanemab works against dementia and who is eligible for it Hope for Alzheimer's patients: Earlier this week, the European Commission approved the first antibody drug for the treatment of Alzheimer's in Europe. The active ingredient, lecanemab, can slow the progression of the disease in some early-stage Alzheimer's patients, but cannot cure or stop it. Early diagnosis of the first symptoms of dementia remains
