Less ice in the Arctic Ocean has complex effects on marine ecosystems and ocean productivity      (via sciencedaily.com)     Original source 

Most of the sunlight reaching the Arctic Ocean is reflected to space by sea ice, effectively shielding ocean ecosystems from sunlight. As the Arctic sea ice continues its downward trend, larger areas of the ocean become exposed to sunlight for longer periods, potentially allowing more primary production on the seafloor. However, according to a new study, this anticipated increase in primary production does not seem to be occurring uniformly across the Arctic Ocean.

Researchers use GPS-tracked icebergs in novel study to improve climate models      (via sciencedaily.com)     Original source 

Research unearthed new information to help scientists better understand circulation patterns of ocean water around glaciers. In the summers of 2014 and 2019, a group of pioneers in glacial research attached GPS devices to 13 icebergs and tracked hourly changes in their positions as they passed through Greenland's Ilulissat Icefjord toward the ocean. Study results showed circulation in the primary fjord is greatly affected by freshwater flow from connecting tributary fjords, which is critically important to consider in circulation models.

Nanocarrier with escape reflex      (via sciencedaily.com)     Original source 

Protein-based drugs must be transported into cells in a way that prevents their immediate degradation. A new approach is intended to ensure that they remain intact only in certain cells, such as cancer cells. A Japanese research team has introduced a nanocarrier that can 'escape' from endosomes before its cargo is destroyed there. This ability to escape is only triggered within the endosomes of certain tumor cells.
