A hypothesis for how the universe got its magnetic field
When we look out into space, all of the astrophysical objects that we see are embedded in magnetic fields. This is true not only in the neighborhood of stars and planets, but also in the deep space between galaxies and galactic clusters.

After reading this, my question is: How can #plasma exist at a particle (molecule?) per cubic meter in space? #askFedi
Source of my query was this recent article:
Long-hypothesized 'next generation wonder material' created for first time
For over a decade, scientists have attempted to synthesize a new form of carbon called #graphyne with limited success. That endeavor is now at an end, though, thanks to new research from the University of Colorado Boulder.

#Vegan diets in children may bring heart benefits but pose growth risks
Children on vegan diets have a healthier cardiovascular profile and less body fat than their omnivore peers, but the diets may affect growth, bone mineral content and micronutrient status, according to researchers from UCL and the Children's Memorial Health Institute in Warsaw.

Quantum weirdness is opening new doors for electron microscopes, powerful tools used for high-resolution imaging.

Split an electron like a wave, send it past a sample, record which slit it came back in from and measure its properties, #science, and you have yourself an image.
I always marvel at things like this. Very impressive.
Mitochondria Double as Tiny Lenses in the Eye
The optical properties of mitochondrial bundles in the retina may improve how efficiently the eye captures light.

> Instead of being obstacles, the mitochondrial bundles seem to play a critical role in helping to funnel as much light as possible to the photoreceptors with minimal loss
California start-up sends tiny robots on voyage into brains
Sending miniature robots deep inside the human skull to treat brain disorders has long been the stuff of science fiction—but it could soon become reality.

Impressive but at the same time, pretty scary. Also, after puncturing a cyst, do they just wait for the brain to absorb the fluid? And how exactly is thus guided with "#magnets"? Very sparse on information
Omicron is trouncing the argument for “natural immunity” to #COVID
Bad news if you're #unvaccinated and think you have strong #protection after #omicron.
> The unvaccinated people fared the worst, producing a mean 50 percent neutralizing antibody titer of just 79.5 against omicron. The mean titer against omicron in vaccinated people was 680. Unvaccinated people also had low-to-negligible levels of neutralizing antibodies against the other five variants.
Men and women process pain signals differently
A new study published in the journal Brain shows for the first time that neurons in the spinal cord process pain signals differently in women compared to men. The finding could lead to better and more personalized treatments for chronic pain, which are desperately needed, especially in light of the opioid epidemic.

Engineers develop a 'magnetic #tentacle robot' to pass into the narrow tubes of the lung
Engineers and scientists have developed proof of concept for a #robot that can reach some of the smallest bronchial tubes in the lungs to take tissue samples or deliver cancer therapy.

Way cool, but also really scary...
#Immune cells were cultured on a chip and acted as if they were in the body. I doubt we'll completely move away from animal testing, but it seems like a great step towards less animal testing.

Computer science professor takes a 'hands-on' approach to smartphone security
As smartphones have grown more sophisticated over the years, so too have their accompanying security measures. Simple passwords have been replaced by thumbprints and facial recognition. However, those methods do not solve the issue of notification privacy.

We Finally Understand how Black Holes can Release Powerful Flares - Universe Today
While black holes might always be black, they do occasionally emit some intense bursts of light from just outside their event horizon. Previously, what exactly caused these flares had been a mystery to science. That mystery was solved recently by a team of researchers that used a series of supercomputers to model the details
