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
Physicists, chemists and immunologists at McMaster University have teamed up to modify red blood cells to transport viral agents which can safely trigger the immune system to protect the body against SARS-CoV-2, creating a promising new vehicle for vaccine delivery. Hamilton, March 13, 2022.- Developing new strategies and vaccine technologiesContinuar Leyendo
Danish and Swedish researchers have dated the enormous Hiawatha impact crater, a 31 km-wide meteorite crater buried under a kilometer of Greenlandic ice. The dating ends speculation that the meteorite impacted after the appearance of humans and opens up a new understanding of Earth’s evolution in the post-dinosaur era. Copenhagen,Continuar Leyendo
Irish and German scientists have just identified how specific immune cells can work together in fat to cause inflammation that leads to weight gain and obesity. Their work pinpoints new avenues to exploit the regulation of that inflammation in fat tissue, thereby suggesting new ways to manage obesity [Wednesday 9thContinuar Leyendo
Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, researchers at Leiden Observatory in the Netherlands have for the first time detected dimethyl ether in a planet-forming disc. With nine atoms, this is the largest molecule identified in such a disc to date. It is also a precursor of largerContinuar Leyendo
