1.5°C Paris Climate Agreement target too high for polar ice sheets and sea level rise
2025-05-20
Efforts to limit the global temperature increase to 1.5°C under the Paris Climate Agreement may not go far enough to save the world’s ice sheets, according to a new study.
Research led by Durham University, UK, suggests the target should instead be closer to 1°C to avoid significant losses from the polar ice sheets and prevent a further acceleration in sea level rise.
The team reviewed a wealth of evidence to examine the effect that the 1.5°C target would have on the ice sheets in Greenland and Antarctica, which together store enough ice to raise global sea levels by almost 65 metres.
The mass of ice lost from these ice ...

Technique rapidly measures cells’ density, reflecting health and developmental state
2025-05-20
CAMBRIDGE, MA -- Measuring the density of a cell can reveal a great deal about the cell’s state. As cells proliferate, differentiate, or undergo cell death, they may gain or lose water and other molecules, which is revealed by changes in density.
Tracking these tiny changes in cells’ physical state is difficult to do at a large scale, especially with single-cell resolution, but a team of MIT researchers has now found a way to measure cell density quickly and accurately — measuring up to 30,000 cells in a single hour.
The researchers also showed that density ...
Mask users can now breathe easy on two counts
2025-05-20
Tokyo, Japan—The COVID-19 pandemic increased public awareness of the importance of mask use for personal protection.
