North Sea efficient sink for carbon dioxide
... ever for a coastal sea. Bozec used these data to calculate how much carbon dioxide the North Sea absorbs from the atmosphere each year and then stores in the deep North Atlantic Ocean. This storage capacity was found to be almost three times as high as the average for all of the world's seas. When the data o...Scientists learn to predict protein-stabilizing ability of small molecules
...ical science. What we've done is shown that we can calculate how osmolytes will influence the stability of different proteins, and we've also determined how different parts of the proteins interact with the osmolytes, which can give us significant insights on the protein-folding process."

Often acute and chronic illness care competes with delivery of preventive services, therefore crowding out prevention services.

Managers now have a new tool to assign and calculate fuel loadings and other fuelbed characteristics anywhere in the continental United States, making the job of estimating fire hazard and fire effects faster and more accurate.

For each discarded placenta, the researchers calculate there are about 300 million amniotic epithelial cells that potentially could be expanded to between 10 and 60 billion cells relatively easily.

Since 1986, 19 out of 50 reported dead right whales were killed by collisions with vessels, and at least six confirmed deaths were from fishing gear ...Insight into cell metabolism will help interpret PETs, MRIs

If you calculate the abundance of whale falls on the sea floor say for grey whales in the northeast Pacific, the neighboring whale falls are about 5-10 kilometers away, which is a very reasonable dispersal distance for the animals that live on them, says Smith.
