The ordinary person can tell by looking at their body temperature how much heat their muscles, organs, and brain are producing. A recent study argues that our muscles have evolved a clever mechanism to keep us warm even when they aren’t working, which lends support to this hypothesis.

Researchers from the University of Queensland claim that mammals’ resting muscles generate more heat, which can subsequently be transferred to other parts of the body.

Warm-blooded mammals, like humans, and cold-blooded animals, like frogs and toads, employ the same fundamental muscle structures to generate force for posture and movement, according to Bradley Launikonis, an associate professor at the UQ School of Biomedical Science.

This study adds to our understanding of how mammals evolved and lays the groundwork for future efforts to harness our muscles’ ability to burn calories while we’re at rest.

For instance, this might help obese individuals lose weight.

More than halfway across the known universe, astronomers have observed an act of tremendous violence as a black hole rips apart a star that got too close to this celestial savage. But this was not your typical case of a hungry black hole.

It was one of only four examples – and the first since 2011 – of a black hole observed in the act of tearing apart a passing star in what is called a tidal disruption event and then launching luminous jets of high-energy particles in opposite directions into space, researchers said. And it was the most distant and brilliant such event ever observed.

A supermassive black hole estimated to be hundreds of millions of times as large as our sun and located about 8.5 billion light years from Earth looks to be the culprit. 5.9 trillion miles is the distance that light travels in a year, or a light year (9.5 trillion km).

According to University of Minnesota astronomer and study co-author Michael Coughlin, “when a star dangerously approaches a black hole – no worries, this will not happen to the sun – it is violently ripped apart by the black hole’s gravitational tidal forces – similar to how the moon pulls tides on Earth but with greater strength.” (Watch the tidal disruption event animation.)

Much like the Milky Way and most galaxies, the supermassive black hole is thought to be located at the centre of a galaxy. However, the tidal disruption event was so intense that it blocked out the stars of the galaxy.

Washington: NASA’s unmanned Orion spacecraft has broken the previous record set in 1970 by the astronauts of the failed Apollo 13 Moon landing mission.

During the Artemis I mission, the unmanned Orion spacecraft from NASA travelled the furthest from Earth: 268,563 miles (432,210).

The previous record was established during the Apollo 13 mission, which was 400,171 kilometres (248,655 miles) from Earth.

NASA released a statement late on Monday saying, “The spacecraft also captured photos of Earth and the Moon together throughout the day, including of the Moon appearing to eclipse Earth.”

Soon, the spacecraft will use the Moon’s gravitational pull once more, together with a precisely planned lunar flyby burn, to hurl Orion back toward Earth in preparation for its December 11 splashdown in the Pacific.

The systems needed for astronauts to survive and breathe in outer space will be put to the test during the Artemis II mission.
