Pine Island Glacier's ice shelf is ripping apart, speeding up key Antarctic glacier
Pine Island Glacier's ice shelf lost about one-fifth of its total area between 2017 and 2020, in three dramatic collapses. Meanwhile the glacier sped up by 12%. The rest of the ice shelf, the authors say, could disappear much sooner than previous studies had suggested.

Promising ovarian cancer treatment proves effective and efficient
Preclinical trials of a new radiopharmaceutical to treat ovarian cancer have produced successful results, dramatically limiting tumor growth and decreasing tumor mass. Designed specifically for ovarian cancers that are resistant to traditional therapies, the new radiopharmaceutical can be produced in 25 minutes at low cost, which leads to better efficiency compared with alternative methods. This research was presented at the Society of Nuclear Medicine and Molecular Imaging 2021 Annual Meeting.

An omega-3 that's poison for tumors
3D tumors that disintegrate within a few days thanks to the action of a well-known omega-3 (DHA, found mainly in fish) -- this is the exceptional discovery by University of Louvain researchers.Hungry for fatty acids, tumor cells in acidosis gorge themselves on DHA but are unable to store it correctly and literally poison themselves. The result? They die.
