Ihaca, NY, May 25, 2025.- Polyethylene and polypropylene account for two-thirds of the world’s plastics. But the polymers’ popularity has an equally large downside. Because they have similar densities and physical properties, the polymers are difficult – and expensive – to separate when mechanically recycled together. What results is aContinuar Leyendo
Astronomers see evidence of clouds bubbling up over Titan’s northern hemisphere. A science team has combined data from the NASA/ESA/CSA James Webb Space Telescope and the Keck II telescope to see evidence of cloud convection on Saturn’s moon Titan in the northern hemisphere for the first time. Most of Titan’sContinuar Leyendo
An international team of researchers, led by the University of Vienna and the Helmholtz Institute for Pharmaceutical Research Saarland, has discovered saarvienin A, a new type of glycopeptide antibiotic. Their findings, now published in Angewandte Chemie International Edition, introduce a compound with strong activity against highly resistant bacterial strains. Vienna,Continuar Leyendo
New York, May 14, 2025.- Fanconi anemia is an aggressive, life-threatening disorder. Most individuals living with this rare genetic condition, characterized by bone marrow failure and cancer predisposition, survive into adulthood only with bone marrow transplantation and regular cancer screening. But a new study demonstrates that mutations in one particularContinuar Leyendo
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
The NASA/ESA/CSA James Webb Space Telescope has captured new details of the auroras on our Solar System’s largest planet. The dancing lights observed on Jupiter are hundreds of times brighter than those seen on Earth. With Webb’s advanced sensitivity, astronomers have studied the phenomena to better understand Jupiter’s magnetosphere. París,Continuar 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
París, April 23, 2025.- In celebration of the NASA/ESA Hubble Space Telescope’s 35 years in Earth orbit, an assortment of compelling images have been released today that were recently taken by Hubble. This stretches from the planet Mars to dramatic images of stellar birth and death, to a magnificent neighbouringContinuar Leyendo
