Frog Hidden Object Game Wins Photo Contest Tonality: This Southeast Asian rice field frog (Fejervarya limnocharis) is barely distinguishable from the bark of the tree it sits on. With its gray-brown color, the frog is almost perfectly camouflaged in this environment. This camouflage protects the approximately four-centimeter-long tiny creature from predators while simultaneously stalking its prey undetected and catching them from behind. Southeast Asian rice-field frog (Fejer

Hemoglobin-like protein absorbs carbon monoxide from the blood Promising antidote: Carbon monoxide poisoning can be fatal – and so far, it can only be treated in hyperbaric chambers. But a newly developed protein could help treat CO poisoning more easily, quickly, and effectively. The new designer protein is based on a bacterial model, resembles our blood hemoglobin, and, unlike previous approaches, has no side effects. The natural protein RcoM served as a template for the de

Folding helpers organize themselves into specialized units in our cells Piecework: Biologists have discovered that small factories exist in our cells where amino acid chains are folded into functional proteins like an assembly line. According to the researchers, the already known helper proteins, which transform the newly produced proteins into their 3D form, are organized into previously unknown specialized units: droplet-like condensates. If these "factories" are missing, t

How "normal" medications pave the way for pathogens Unexpectedly common side effect: Not only antibiotics, but also a surprisingly large number of other classes of active ingredients weaken our intestinal flora and thus the natural protective function of the intestine. As a result, pathogenic bacteria such as salmonella can more easily colonize there, as researchers report in "Nature." These side effects of common medications have so far been overlooked, but should be taken i

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

Late caffeine consumption keeps our brain awake even while we sleep A wake-up call even while we sleep: If we drink coffee late in the evening, it has consequences for our brain. A study shows that caffeine alters our sleep and keeps our brain more alert at night. This hinders the recovery of our brain and could also disrupt nighttime memory formation. Researchers found that this stimulating coffee effect is more pronounced in younger people than in older people. Caffeine aff

"Art" from Cancer Cells Wins Endocrine Images Art Competition This bright pink and blue image could probably hang in a modern art museum. But this "art" was created by Mother Nature: It shows cells of an aggressive thyroid cancer subtype. They were brought to light by endocrinologist Sriram Gubbi. The Endocrine Society has now awarded him first place in the Endocrine Images Art Competition for his spectacular photograph. This pink-blue explosion of color shows malignant cance
