Alzheimer’s disease is the most common and best known of the tauopathies, a set of neurodegenerative brain diseases caused by toxic tangles of the protein tau. A study by researchers at Washington University School of Medicine in St. Louis has shown that targeting astrocytes — an inflammatory cell in theContinuar Leyendo
Children previously infected with COVID-19 develop natural circulating antibodies that last for at least seven months, according to a new study led by researchers at UTHealth Houston. The study was published today in Pediatrics. Houston, March 20, 2022.- Researchers examined data from 218 children across the state of Texas betweenContinuar Leyendo
Nearly 15 years after the discovery of fast radio bursts (FRBs), the origin of the millisecond-long, deep-space cosmic explosions remains a mystery. Las Vegas, March 20, 2022.- That may soon change, thanks to the work of an international team of scientists — including UNLV astrophysicist Bing Zhang — which trackedContinuar Leyendo
While many people in wealthier countries have been vaccinated against Covid-19, there is still a need for vaccination in much of the world. A new vaccine developed at MIT and Beth Israel Deaconess Medical Center may aid in those efforts, offering an inexpensive, easy-to-store, and effective alternative to RNA vaccines.Continuar Leyendo
París, March 15, 2022.- At 19:24 UTC on 11 March 2022, astronomer Krisztián Sárneczky discovered a bright and fast-moving new object in the sky using the 60cm Schmidt telescope at the Piszkéstető observatory, Hungary. He collected four observations in quick succession, and just 14 minutes later reported his findings toContinuar Leyendo
A new study from MBARI researchers and their collaborators is the first to document how the thawing of permafrost, submerged underwater at the edge of the Arctic Ocean, is affecting the seafloor. The study was published in the Proceedings of the National Academy of Sciences on March 14, 2022. MossContinuar Leyendo
Irradiation with fast protons is a more effective and less invasive cancer treatment than X-rays. However, modern proton therapy requires large particle accelerators, which has experts investigating alternative accelerator concepts, such as laser systems to accelerate protons. Such systems are deployed in preclinical studies to pave the way for optimalContinuar Leyendo
Briefly blocking a key molecule when administering the only approved vaccine for tuberculosis vastly improves long-term protection against the devastating disease in mice, researchers from Texas Biomedical Research Institute report this week in the Journal of Immunology. The finding, if it continues to hold true in nonhuman primates and clinicalContinuar Leyendo
By uncovering the subtle difference between two varieties of a protein, researchers from the Perelman School of Medicine at the University of Pennsylvania may have discovered how to eliminate the risk of weight gain from a certain type of diabetes medication. Through this, it’s possible that more patients with diabetesContinuar Leyendo
Tiny structures called nanoparticles can be used to carry substances to certain parts of the body — for example, to deliver a chemotherapy drug to a tumor. Although such «nanomedicine» offered hope for improving cancer therapeutics, the survival benefits of clinically approved nanomedicines are often modest when compared with conventionalContinuar Leyendo
