Cancer cells proliferate despite a myriad of stresses — from oxygen deprivation to chemotherapy — that would kill any ordinary cell. Now, researchers at UC San Francisco have gained insight into how they may be doing this through the downstream activity of a powerful estrogen receptor. The discovery offers cluesContinuar Leyendo
A team of paleontologists from the University of Washington and its Burke Museum of Natural History and Culture excavated four dinosaurs in northeastern Montana this summer. All fossils will be brought back to the Burke Museum where the public can watch paleontologists remove the surrounding rock in the fossil preparationContinuar Leyendo
A study published in the journal Geology rules out that extreme volcanic episodes had any influence on the massive extinction of species in the late Cretaceous. The results confirm the hypothesis that it was a giant meteorite impact what caused the great biological crisis that ended up with the non-avianContinuar Leyendo
Researchers at the University of Illinois Urbana-Champaign watched fragments of two meteors as they ramped up the heat from room temperature to the temperature it reaches as it enters Earth’s atmosphere and made a significant discovery. The vaporized iron sulfide leaves behind voids, making the material more porous. This informationContinuar Leyendo

Researchers at Washington University School of Medicine in St. Louis have developed an approach to estimating when a person who is likely to develop Alzheimer’s disease, but has no cognitive symptoms, will start showing signs of Alzheimer’s dementia. St.Louis, September 18, 2021.- The algorithm, available online in the journal Neurology,Continuar Leyendo
New research shows that Multiple Sclerosis (MS) patients undergoing anti-CD20 (aCD20) treatment — which depletes the B cells that contribute to the MS attacks — are able to mount robust T-cell responses to the mRNA COVID-19 vaccines, despite having a muted antibody response to the vaccines. Philadelphia, September 17, 2021.-Continuar Leyendo
