The frigid Arctic Ocean is far removed from the places most people live, but even so, ‘forever chemicals’ reach this remote landscape. Now, research suggests that per- and polyfluoroalkyl substances (PFAS) won’t stay there indefinitely. Instead, they are transported in a feedback loop, with the Arctic Ocean potentially exporting as many PFAS to the North …
PFAS flow equally between Arctic Ocean and Atlantic Ocean Read More »
To address natural resource scarcity, pollution, and other harmful effects of climate change, some scientists and policymakers emphasize the adoption of input-efficient technologies like water-saving devices and fuel-saving stoves. Proponents often refer to these input-efficient technologies as ‘win-win,’ for the benefits to their users and to the environment, and lament their low adoption rates by …
No win-win? Input-efficient technologies might not be so efficient after all Read More »
Sterol regulatory element-binding proteins (SREBPs) play a crucial role in lipid biosynthesis. In a recent study, researchers identified a novel cleavage enzyme of SREBP-1c, a key player in fatty acid biosynthesis. Moreover, the team unveiled, for the first time, that the biosynthesis process of fatty acid in the liver is activated by saturated fatty acids …

The number of infections by the tick-borne TBE virus that are not detected by health services is far higher than previously assumed. This has been shown in a new study of Swedish blood donors.

Researchers have used a soft, wearable robot to help a person living with Parkinson’s walk without freezing. The robotic garment, worn around the hips and thighs, gives a gentle push to the hips as the leg swings, helping the patient achieve a longer stride. The device completely eliminated the participant’s freezing while walking indoors, allowing …
