Let’s take a deeper look at the “Cat video from Space” that was beamed down on Dec 11.
It was sent using laser optics from the NASA Psyche spacecraft as part of Deep Space Optical Communications (DSOC) technology demo.
Distance to Psyche: 31 mil km; 0.2 AU; 101 light seconds; 80x distance to the moon
Video length: 15 sec
Data rate: 267 Mbps 😲
Video quality: UltraHD (4K or 8K?)
Compressed video rate: Probably 20-50 Mbps
The download probably took just a few seconds. https://www.youtube.com/watch?v=GvJtVOmFs5Q

The insects in the spotlight this year were bedbugs, which ravaged first Paris (during Fashion Week, no less) and then Asia. But buggy concerns go far beyond this.
While pests are spreading and making pests of themselves, there’s a parallel problem of insect decline (sometimes called the “insect apocalypse”).
Latest research analysis lend further physical evidence modern humans and neanderthals lived side by side and interbred for several thousand years before neanderthals became extinct.
Have you noticed any changes in your local birdsong?
Scientists are finding that several species of urban-dwelling birds have modified their songs in response to human-generated noise #NationalBirdFeedingMonth
Within the last decade or so, sports psychology research has exploded, as scientists have explored the nuances of everything from the pursuit of perfection to the harms of abusive coaching.
#FromTheArchives: Will glow-in-the-dark materials someday light our cities?
Substances that persistently luminesce are already used in some bike lanes, and in the future could be applied to sidewalks, streets and buildings — saving energy and reducing urban heat.
Alexander Refsum Jensenius @arjensenius présente la fin de la collecte de données pour son travail de recherche sur la station debout et les micro-mouvements, effectué sur une année, posté ici chaque jour avec #StillStanding (en Anglais) :
A massive bias in medical studies toward men of European origin means that genetic variants in understudied populations don’t get the focus they deserve, writes bioinformatician and Annual Reviews co-author Manuel Corpas.
Many mangrove restorations fail. Is there a better way?
These carbon-hoarding, coastline-protecting forests are sponges for greenhouse gases. Doing plantings right and involving local communities are key to saving them:
