Early interventions could help counteract muscle loss

Science Daily - 30/11/2021
Weakening muscles are a natural part of the aging process, but for some people with a condition called sarcopenia the decline is abnormally fast. A new study suggests that the early stages of sarcopenia could be counteracted with timely interventions designed to preserve physical and cognitive function and manage chronic conditions.

Closest pair of supermassive black holes yet

Science Daily - 30/11/2021
Astronomers have revealed the closest pair of supermassive black holes to Earth ever observed. The two objects also have a much smaller separation than any other previously spotted pair of supermassive black holes and will eventually merge into one giant black hole.

Warm-water habitat 'pays the bills,' allowing cold-water fish to fuel up

Science Daily - 30/11/2021
New research shows that warm-water habitats can be critically important for the survival of cold-water fish such as trout and salmon.

Researchers model circadian clock neurons in a day-active animal

Science Daily - 30/11/2021
It's no secret that jet lag and night-shift work can wreak havoc on the way our body's internal clock syncs up our daily wake-sleep cycle, known as circadian rhythm, but now researchers say they are a step closer to understanding how the brain creates behavioral rhythms optimized for diurnal, rather than nocturnal, life.

Satellites reveal Ethiopian elephants under threat

Science Daily - 30/11/2021
Tens of thousands of illegal human settlements pose a real threat to the continued existence of an endangered elephant population, according to satellite analysis of the Babile Elephant Sanctuary in eastern Ethiopia.

Rates of type 2 diabetes are higher in people with one of various common psychiatric disorders

Science Daily - 30/11/2021
A new study finds that the prevalence of type 2 diabetes (T2D) is elevated in people with a psychiatric disorder compared with the general population.

Largest comet ever observed was active at near-record distance

Science Daily - 30/11/2021
Astronomers show that comet Bernardinelli-Bernstein (BB), the largest comet ever discovered, was active long before previously thought, meaning the ice within it is vaporizing and forming an envelope of dust and vapor known as a coma. Only one active comet has been observed farther from the sun, and it was much smaller than comet BB.

Strong winds power electric fields in the upper atmosphere

Science Daily - 30/11/2021
Using observations from NASA's ICON mission, scientists presented the first direct measurements of Earth's long-theorized dynamo on the edge of space: a wind-driven electrical generator that spans the globe 60-plus miles above our heads. The dynamo churns in the ionosphere, the electrically charged boundary between Earth and space. It's powered by tidal winds in the upper atmosphere that are faster than most hurricanes and rise from the lower atmosphere, creating an electrical environment that can affect satellites and technology on Earth.
