The field, dubbed the "polar wind," explains how Earth's atmosphere escapes easily and rapidly above the north and south poles, and may have played a role in shaping our planet's thin upper atmosphere.

Common wisdom says depression starts in the mind with distorted thinking. But newer models suggest depression starts when the body initiates a defense strategy to help us survive.
> If depression is the emotional expression of the immobilization response, then the solution is to move out of that state of defense. Porges believes it is not enough to simply remove the threat. Rather, the nervous system has to detect robust signals of safety to bring the social state back online. The best way to do that? Social connection.
For people who don’t prefer social connection, I’ve seen that exercise works well

Neutron star collisions create a strange, dense "soup" of quarks and gluons in the aftermath of the smashup that scientists are studying.
When neutron stars dance together, the grand smash finale they experience might create the densest known form of matter known in the Universe. It’s called “quark matter, ” a highly weird combo of liberated quarks and gluons. It’s unclear if the stuff existed in their cores before the end of their dance. However, in the wild aftermath a neutron-star merger, the strange conditions could free quarks and gluons from protons and neutrons. That lets them move around freely in the aftermath. So, researchers want to know how freely they move and what conditions might impede their motion (or flow).

- • 100%www.livescience.com Chlamydia may hide in the gut and cause repeated infections
A mini model of the human intestines suggests that chlamydia bacteria can colonize the gut, potentially contributing to recurrent infections.
The bacteria behind chlamydia can colonize the gut, and from that hiding place, they may act as a source of repeated infections, new research using miniature intestines suggests.
Chlamydia is the most common sexually transmitted infection (STI) worldwide. The form of the infection that affects humans is caused by a species of bacteria known as Chlamydia trachomatis.
The disease most often affects the genital region, sometimes causing pain and unusual discharge from the vagina or penis. However, over the years, research in mice and various clinical reports in humans have suggested that C. trachomatis may also be able to infect the human digestive tract. This means that, theoretically, the bacteria could hide in the gut and then cause repeated genital infections, which commonly occur in patients despite treatment with antibiotics.
Yet, until now, scientists haven't been able to test this theory in human cells.
