Broadly effective innovative vaccine design. Globally, approximately 58 million people are chronically infected with HCV, resulting in 290,000 annual deaths due to complications such as liver cirrhosis and liver cancer. Although modern antiviral treatments achieve high cure rates, the global elimination of HCV remains a difficult goal due to inadequate early detection and limited treatment options. Indeed, HCV has been identified as one of the globally prioritized endemic pathogens for vaccine research and development in the World Health Organization’s “Immunization…
Circadian clocks control physiological processes and behavior in virtually all living organisms. Now an international research team led by researchers from the University of Würzburg has created a detailed map of the internal clock in the brain of the fruit fly. All animals including humans are subject to daily rhythms in their activity and sleep, hunger, metabolism, and reproduction. The system that regulates these biological rhythms is known as the circadian clock. It controls all processes in the body within…
Microbial communities, such as those found in the gut microbiome or other body regions, are crucial for the health and development of hosts. However, understanding how these microbes interact with each other – whether they compete, cooperate, or influence each other indirectly – has been difficult to decipher. A new method now sheds more light on this issue: an innovative stochastic approach that allows for more precise analysis of interactions between microbes. Traditional models for analyzing microbial communities often rely…
A Path to Innovative Vaccines and Therapies. A research team led by Prof. Julia Esser-von Bieren from the Center of Allergy and Environment (ZAUM) at Helmholtz Munich and the Technical University of Munich, as well as the University of Lausanne (UNIL) has uncovered a molecular strategy employed by worm parasites (helminths) to evade host immune defenses. This discovery opens new avenues for the development of innovative vaccines and therapies. Published in Science Immunology, the study offers promising solutions for addressing…
New research has revealed that fish embryos actively control their hatching timing through a neurohormone, Thyrotropin-Releasing Hormone (TRH), which triggers the release of enzymes that dissolve the egg wall. This groundbreaking discovery uncovers a previously unknown neural mechanism that governs a critical life-stage transition, showing that embryos are not passive but instead actively make life-or-death decisions. The finding has significant evolutionary implications, offering new insights into neurobiology, survival strategies, and environmental adaptation in vertebrates. Dr. Matan Golan of the Hebrew…
Liquid water molecules are inherently asymmetric. Icebergs float on liquid water, 4°C cold water sinks to the bottom: With its anomalies, water still poses a number of scientific puzzles. Researchers led by Johannes Hunger at the Max Planck Institute for Polymer Research have investigated the bonds between a water molecule and its neighbors in the liquid phase. They have discovered that the distances to neighboring molecules are not just randomly distributed: The two hydrogen atoms of a water molecule form…
Kumamoto University scientists have unveiled a novel compound, HPH-15, with dual effects of reducing blood glucose levels and combating fat accumulation, marking a significant leap in diabetes treatment innovation. Type 2 diabetes, a condition affecting millions worldwide, is often accompanied by complications like fatty liver and insulin resistance, which challenge current treatment methods. The research team, led by Visiting Associate Professor Hiroshi Tateishi and Professor Eiichi Araki, has identified HPH-15 as a promising alternative to existing medications like metformin. The…
Speed and precision unlocked… A novel computational technique offers a faster, more accurate approach for measuring bioactive carotenoids, reducing error rates and analysis time. Carotenoids, the pigments responsible for the vibrant hues of tomatoes, carrots, and some seafood, are well-regarded for their antioxidant effects and health benefits. A few examples of commercially significant carotenoids are lycopene, β-carotene, and astaxanthin. These compounds are frequently used in functional foods, skincare products, and dietary supplements. However, the bioactivity of these carotenoids depends heavily…
With a novel approach, EMBL scientists discovered important interactions between molecular machines, potentially offering new opportunities for drug development. Choosing a film for a movie night is always a battle. Now imagine if you could pick one that provided a window into some of the most fundamental biological processes that keep us alive. For the first time ever, researchers have captured a real-time molecular movie to show how two essential cellular processes – transcription and translation – interact with each…
Researchers at the Leibniz Institute of Vegetable and Ornamental Crops (IGZ) investigated the seasonal variation in glucosinolates and their enzymatic hydrolysis products in red and white cabbage, as well as broccoli. The results provide crucial insights for cultivating and utilizing these vegetables for healthy diets and functional food production. The study was carried out on the IGZ experimental fields in Großbeeren in three consecutive years from 2020 to 2022. It revealed that red cabbage shows significant variation in the amounts…
Researchers at TU Delft have discovered that E. coli bacteria can synchronise their movements, creating order in seemingly random biological systems. By trapping individual bacteria in micro-engineered circular cavities and coupling these cavities through narrow channels, the team observed coordinated bacterial motion. Their findings, which have potential applications in engineering controllable biological oscillator networks, were recently published in Small. An audience clapping in rhythm, fireflies flashing in unison, or flocks of starlings moving as one – synchronisation is a natural…
Researchers from the Organoid group (previously Clevers group) at the Hubrecht Institute have developed a new organoid that mimics the human fetal pancreas, offering a clearer view of its early development. The researchers were able to recreate a complete structure that includes the three key cell types in the pancreas, which previous organoids couldn’t fully mimic. Notably, the team identified a new stem cell that develops into the three cell types. These findings, published in Cell on December 2nd, could help…
Culinary foam made from the whites of chicken eggs makes baked goods light and airy. In the LeguFoam project, Fraunhofer researchers are working on a plant-based alternative made from legumes. “More and more people are consciously maintaining a healthy diet and also looking for ethical unproblematic vegan products. We are addressing this need with the LeguFoam project,” explains Dr. Maike Föste, senior research scientist in the Food Process Development department at the Fraunhofer Institute for Process Engineering and Packaging IVV…
Worldwide, consumption of sugar has risen steadily in recent decades even though this food contributes to cavities, high blood pressure and widespread health issues such as type 2 diabetes and cardiovascular disease. In the joint research project NovelSweets, researchers at the Fraunhofer Institute for Molecular Biology and Applied Ecology IME have teamed up with partners to use methods derived from biotechnology to produce innovative, protein-based sweeteners. Their goal is to replace sugar and existing sugar alternatives, especially in beverages. The…
It’s a big year for microRNAs. The 2024 Nobel Prize in Physiology or Medicine went to Victor Ambros and Gary Ruvkun, who discovered the first microRNA in 1993. Today, we know that humans make more than 1,000 different microRNAS. These molecules are critical for building and maintaining healthy bodies, so it’s crucial that they’re made the right way. Errors in microRNA manufacture can put us at risk for developmental disorders, cancer, or neurodegenerative disease. To learn how cells accurately generate…
…solved by integrated approach. A collaborative effort by the research groups of Professor Haruhiko Fuwa from Chuo University and Professor Masashi Tsuda from Kochi University has culminated in the structure elucidation and total synthesis of anticancer marine natural products, iriomoteolide-1a and -1b. These natural products were originally isolated from the marine dinoflagellate collected off the Iriomote Island, Okinawa, Japan. Because of its potent anticancer activity, iriomoteolide-1a is an intriguing natural product that attract immense attention from the chemical community around…
