Summary:
New US Covid infections for the week ending January 16th were 8.5% below those of the week ending January 9th, so it appears that the incidence of new cases mat have peaked and is turning down, at least for the time being. One caveat to that, though, is that we don t know how many of the prior week s cases were from reports that had been delayed over the holidays. For a check on that, we can compare new cases from the week ending January 16th to those from the week ending December 19th, two weeks which sh

As ocean waters increasingly acidify due to absorbing carbon dioxide, tracking impacts on specific species has been difficult to gauge over time. Most of what is known about species responses to acidifying waters comes from short-term experiments that suggest increases in ocean acidity causing a lowering of seawater pH and less availability of carbonate ions to make shells can lead to less fortified shells and more vulnerable animals. But not every species from the studies responds the same way, with some even appearing to do better under those conditions.
Comparing new data with samples collected in the 1950s, UCSD s Division of Biological Sciences graduate student Elizabeth Bullard and Professor Kaustuv Roy found that ocean acidification is transforming the composition of California mussel shells from mostly the mineral aragonite to the mineral calcite. The results are published in the Proceedings of the National Academy of Sciences.
