In a new study, scientists at the University of Missouri demonstrate the direct transmission of bisphenol A (BPA) from a mother to her developing child via the placenta could negatively impact fetal brain development. Cheryl Rosenfeld, a professor of biomedical sciences in the College of Veterinary Medicine, and colleagues proposeContinuar Leyendo
París, Jan 10, 2022.- Today the James Webb Space Telescope team successfully fully deployed its iconic 6.4-metre, gold-coated primary mirror, completing the final stage of all major spacecraft deployments to prepare for science operations. “The successful unfolding of the Webb telescope has been a complex but impressive engineering masterpiece. OnContinuar Leyendo

Led by the University of Bern, an international research team has discovered a sub-Neptune exoplanet orbiting a red dwarf star. The discovery was also made thanks to observations performed by the SAINT-EX observatory in Mexico. SAINT-EX is run by a consortium including the Center for Space and Habitability (CSH) atContinuar Leyendo
For the first time ever, astronomers have imaged in real time the dramatic end to a red supergiant’s life — watching the massive star’s rapid self-destruction and final death throes before collapsing into a type II supernova. Evanston, Jan 07, 2022.- Led by researchers at Northwestern University and the UniversityContinuar Leyendo
A trial by the University of Eastern Finland found that taking a much higher dose of vitamin D than recommended for five years did not affect total mortality or the incidence of cardiovascular disease or cancer in older men and women. Joensuu/Kuopio, Jan 07, 2022.- In population studies, low levelsContinuar Leyendo
The first comprehensive analysis of viral horizontal gene transfer (HGT) illustrates the extent to which viruses pick up genes from their hosts to hone their infection process, while at the same time hosts also co-opt useful viral genes. Vancouver, Jan 06, 2022.- HGT is the movement of genetic material betweenContinuar Leyendo
The brain has a natural protective mechanism against Alzheimer’s disease, and researchers at Baylor College of Medicine, Texas Children’s Hospital and collaborating institutions have discovered that gene variants associated with risk of developing the disease disturb the protective mechanism in ways that can lead to neurodegeneration. The researchers also showedContinuar Leyendo
The NASA/ESA/CSA James Webb Space Telescope team has fully deployed the spacecraft’s sunshield in space, a key milestone in preparing it for science operations. The sunshield – about the size of a tennis court at full size – was folded to fit inside the Ariane 5 rocket’s nose cone priorContinuar Leyendo
