By Patricia Waldron New York, May 14, 2025.- Telling the difference between benign and cancerous thyroid nodules before surgery is notoriously challenging, but a new study finds that a combination of artificial intelligence and data analysis techniques may yield surprisingly accurate cancer predictions. The proof-of-concept study was conducted by researchersContinuar Leyendo
New York, May 11, 2025.- A tiny chemical modification commonly found on messenger RNAs plays a surprisingly large role in how cells respond to stress, according to a study led by Weill Cornell Medicine investigators. The finding clarifies an important aspect of cell biology, and may have clinical implications, sinceContinuar Leyendo
Researchers from the University of Bern, Inselspital, Bern University Hospital, and ETH Zurich have developed an innovative technology which can clean implanted medical devices such as ureteral stents and catheters non-invasively, using ultrasound activation through the skin. This could significantly improve the quality of life of patients and at theContinuar Leyendo
Using in-vitro models of a specific type of brain cell, scientists show that neurons are capable of changing from one type to another. Santa Cruz, CA, April 23, 2025.- There are two main types of neurons in the cerebral cortex, the outermost layer of the brain: excitatory, which make upContinuar Leyendo
Scientists from the Institut Pasteur, in collaboration with Kumamoto University in Japan, have assessed a new rapid diagnostic test to identify pregnant women at elevated risk of transmitting hepatitis B to their babies. This diagnostic tool could help eliminate hepatitis B by preventing mother-to-child transmission during childbirth, especially in low-Continuar Leyendo
Ithaca, April 08, 2025.- Knocking out a single gene reprograms part of the large intestine to function like the nutrient-absorbing small intestine. In a preclinical study, Weill Cornell Medicine investigators showed that the technique reversed the malnutrition that results when most of the small intestine is removed. The successful demonstrationContinuar Leyendo
The increase of microbes resistant to antibiotics is a growing problem. These include, for example, Neisseria gonorrhoeae, a bacterium which causes gonorrhea. Researchers from the universities in Konstanz and Vienna discover a new class of antibiotic that selectively targets Neisseria gonorrhoeae. These substances trigger a self-destruction program, which also operatesContinuar Leyendo
Widely used by the food industry, emulsifiers – a type of food additive – are found in many daily foods (sliced bread, ice creams, crème fraîche, plant milks, etc.). Given their omnipresence in our diet, the health effects of their consumption have become a real public health issue. Benoit Chassaing,Continuar Leyendo
Vaccinations alone may not be enough to protect people with compromised immune systems from infection, even if the vaccine has generated the production of antibodies, new research from the University of Cambridge has shown. Cambrigde, Feb 14, 2025.- The findings, published today in Science Advances, suggest that such individuals willContinuar Leyendo
New Yok, Jn 24, 2025.- Some of the body’s cells stay put for life, while others are free to roam. To move, these migratory cells rely on filopodia—sensitive, finger-like protrusions that reach out from the cell membrane into the local environment. In a healthy cell, this can be a lifesaver:Continuar Leyendo
