Like many people in the time of COVID-19, Iâd put on a few pounds. Iâd gone beyond adding my normal layer of winter padding to having to rotate between the two outfits I had left that fit.
And when I say they didnât fit, I mean they physically hurt to wear. My stomach and belt looked like a tree that had grown for a hundred years around a wire fence.
I knew I wasnât up for a lifestyle change, so I went with a fad diet instead. And because Iâm a middle-aged man, I didnât know what the latest fadâ¦

Magnetic Waves Explain Mystery Of Sun’s Outer Layer
A theory as to why the Sun s outer atmosphere differs in its chemical make-up from its inner layers has been confirmed by direct observation for the first time by scientists at UCL and the Italian Space Agency.
The Sun s extremely hot outer layer, the corona, has a very different chemical composition from the cooler inner layers, but the reason for this has puzzled scientists for decades.

One explanation is that, in the middle layer (the chromosphere), magnetic waves exert a force that separates the Sun s plasma into different components, so that only the ion particles are transported into the corona, while leaving neutral particles behind (thus leading to a build-up of elements such as iron, silicon and magnesium in the outer atmosphere).

Now, in a new study published in
The Astrophysical Journal, researchers combined observations from a telescope in New Mexico, the United States, with satellites located near Earth to identify a link between magnetic waves in the chromosphere and areas of abundant ionised particles in the hot outer atmosphere.
Watch out! These tricky monkeys steal things to barter for food, study shows
A primatologist who studied long-tailed macaque monkeys living in the wild says his latest study suggests the primates have developed rudimentary economic decision-making skills, such as bartering.
