UK becomes first nation to approve Omicron vaccine


AUG 16, 2022 Britain has become the first country to authorise a Covid-19 vaccine that targets the Omicron variant. The UK medicine regulator (MHRA) approved the 'bivalent' vaccine made by Moderna as a booster for adults, Reuters reported. The agency's decision was based on clinical trial data that showed the booster triggered "a strong immune response" against both Omicron (BA.1) and the original 2020 virus, it said. The UK medicine regulator also cited an exploratory analysis in which the shot was also found to generate a good immune response against the currently dominant Omicron sub-variants BA.4 and BA.5, Copyright © Jammu Links News, Source: Jammu Links News

Chemists crack complete quantum nature of water

"Now that we have a good template for understanding how water molecules interact among themselves, we have a basis to deepen our understanding of the role of water in biochemical processes essential to life," says Joel Bowman, Emory professor of theoretical chemistry. Chemists have produced the first full quantum mechanical model of water — one of the key ingredients of life. The Journal of Physical Chemistry Letters published the breakthrough, which used machine learning to develop a model that gives a detailed, accurate description for how large groups of water molecules interact with one another. “We believe we have found the missing piece to a complete, microscopic understanding of water,” says Joel Bowman, professor of theoretical chemistry at Emory University and senior author of the study. “It appears that we now have all that we need to know to describe water molecules under any conditions, including ice, liquid or vapor over a range of temperature and pressure.” The researchers developed free, open-source software for the model, which they dubbed “q-AQUA.” The q-AQUA software provides a universal tool for studying water. “We anticipate researchers using it for everything from predicting whether an exoplanet may have water to deepening our understanding of the role of water in cellular function,” Bowman says.
