An anonymous reader quotes a report from The Guardian: All-female astronaut crews could reproduce in space without the help of accompanying men, new research suggests. The study found that frozen samples of sperm exposed to microgravity retained similar characteristics to sperm samples kept on the ground, raising hopes that a sperm bank could one day be set up in space to…

Sperm Can Survive Microgravity, but Don’t Expect Any Space Babies Soon
Frozen sperm didn’t seem fazed by several loop the loops in an aerobatic plane, but that’s a far cry from showing that they would make a healthy baby in space. Source: https://www.livescience.com/65650-sperm-okay-with-microgravity.html
Spherical flames in space could solve the mystery of soot-free fires
In microgravity, flames are sphere-shaped. Tests of fire on the International Space Station are helping show how gases flow within flames. Source: https://www.sciencenews.org/article/spherical-flames-space-could-solve-mystery-soot-free-fires4…

Astronauts may have vision problems because of liquid in their brains
In microgravity, astronauts’ brains fill with fluid and it doesn’t drain for months after they return to Earth, which may be why their vision worsens Source: https://www.newscientist.com/article/2201693-astronauts-may-have-vision-problems-because-of-liquid-in-their-brains/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
‘It Feels Awesome’: NASA Astronaut Learns She Will Spend Record-Breaking 328 Days in Space
Christina Koch has spent the past month orbiting Earth aboard the International Station. Earlier today, the NASA astronaut learned she won’t be coming home for another 10 months. Her prolonged stay—at an estimated 328 days—will establish a new record for the longest spaceflight completed by a woman.Read more…Source: https://gizmodo.com/it-feels-awesome-nasa-astronaut-learns-she-will-spend-1834118108…
Does a year in space make you older or younger?
The NASA Twins study – featuring astronaut twins Scott and Mark Kelly – was the perfect space experiment. Scott spent a year in space aboard the International Space Station. Mark remained on Earth. The results? Source: https://earthsky.org/human-world/year-in-space-human-body-twins-study…
The First Detailed Study of How Mice Behave in Space Reveals Strange, Coordinated Zooming
New research based on experiments done on the International Space Station shows that mice adapt quickly to microgravity conditions. Unexpectedly, however, some of the mice began to exhibit a rather curious circling behavior, zipping around the walls of their metal cage with reckless abandon.
