Researchers have found that the molecule lac-phe, produced after intense exercise, is responsible for weight loss seen in metformin users, linking it to appetite control and metabolism. Studies show that metformin increases lac-phe levels, mirroring the effects of vigorous exercise, suggesting new pathways for developing weight loss drugs.A Stanford Medicine study found that metformin, a commonly prescribed diabetes drug associated with moderate weight loss, stimulates production of lac-phe, a molecule abundant after…

Researchers have discovered that RvT4, a molecule, significantly boosts the body’s defenses against atherosclerosis in rheumatoid arthritis patients by enhancing macrophages’ ability to reduce inflammation and clear vascular blockages. This finding opens up new avenues for treating individuals with rheumatoid arthritis, who are at a heightened risk for cardiovascular diseases. Credit: SciTechDaily.comA new study reveals that RvT4 improves macrophage function to fight atherosclerosis in rheumatoid arthritis, suggesting new…

White blood cells are important foot soldiers in the immune system, but their numbers can be cut by health conditions or treatments like chemotherapy. Yale scientists have now discovered a molecule that can be given to quickly boost their numbers back up, to help fight off infections without antibiotics.Neutrophils are a type of white blood cell that are among the first responders to foreign threats like bacteria, viruses or fungi. Unfortunately, their levels can drop in a condition called neutropenia, which can be the…

It's pretty hard to imagine the world through someone else's eyes, especially different animals. But a new study using lab-grown human retinas reveals that even between different humans, our vision is extremely diverse.And it might be to do with how the red and green cones form in our retinas. Cones are light-sensing cells in vertebrates' eyes; their combined responses to different wavelengths enable color vision.Humans and some closely related primates are some of the only mammals known that can see the color red, as…

Researchers have overturned traditional models of how water molecules behave at the surface of saltwater, revealing new insights into ion distribution and orientation. This breakthrough, achieved through advanced techniques, has significant implications for climate science and technology. Credit: SciTechDaily.comGroundbreaking research shows that water molecules at the saltwater surface behave differently than previously thought, offering new perspectives for environmental science and technology.Textbook models will need…

This illustration shows Saturn’s icy moon Enceladus with the plume of ice particles, water vapor, and organic molecules that sprays from fractures in the moon’s south polar region. Credit: NASA/JPL-CaltechA study zooms in on data that NASA’s Cassini gathered at Saturn’s icy moon and finds evidence of a key ingredient for life and a supercharged source of energy to fuel it.Scientists have known that the giant plume of ice grains and water vapor spewing from Saturn’s moon Enceladus is rich with organic compounds, some of…

The bottom of a ceramic Ding with foodcrust attached to its inner wall. Credit: UCAS A lipid and proteomic study of ancient carbonized material (foodcrust) on pottery from the Taihu Lake region of eastern China has revealed the presence of rice, seafood consumption, various pottery functions, as well as the southward spread and planting of millet during the 4th millennium BCE. …

In a basement room at Austria's University of Graz sits a jumble of steel tanks and ice-encrusted tubes. The contraption, a scanning tunneling microscope, can snap pictures of individual atoms and molecules. It's so sensitive that it works best at night, when nobody's around to walk or talk or otherwise rattle the building.A computer monitor beside the machine shows images of tiny, heart-shaped blobs arrayed over a copper surface. The “hearts” are individual molecules: ditolyl-ATI molecules, to be precise. Earlier this…

Maynooth University researchers have discovered a novel molecule to fight drug-resistant bacteria, leveraging supramolecular chemistry. The new findings offer a potential new approach to antibiotic development, with significant implications for public health. Credit: Ella Maru StudiosResearchers at Maynooth University have developed a new molecule designed to combat drug-resistant bacteria.An international team, including researchers from Maynooth University, has developed a novel molecule with the potential to combat…

Scientists have discovered a new molecule, CUDC-907, which can selectively destroy aging, non-functional cells (senescent cells) without affecting healthy ones, potentially delaying tissue aging and improving life quality and longevity. The molecule, which has shown promising in vitro results and is also being investigated for its anti-cancer effects, will soon be tested in animal models.Scientists from the UOC and the University of Leicester have discovered a molecule with the potential to effectively eliminate senescent…
