‘Ghost Fleas’ Bring Toxic Mercury Up From The Depths Of Prairie Lakes

‘Ghost Fleas’ Bring Toxic Mercury Up From The Depths Of Prairie Lakes

‘Ghost fleas’ bring toxic mercury up from the depths of prairie lakes

How toxic mercury moves through the environment—and accumulates in the fish that people eat—has been known for decades. Now, scientists have discovered an unexpected way that the neurotoxin circulates in lakes, hitching a late-night ride inside small predatory crustaceans dubbed “ghost fleas.” The finding helps explain why some lake fish contain surprising amounts of mercury. It also suggests researchers who sample lakes only during the day might be missing important clues to how those ecosystems work.

Silver nanoparticles show promise in fighting antibiotic-resistant bacteria
New research investigated whether silver nanoparticles could amplify the effects of antibiotics on antibiotic-resistant bacteria.

In a new study, scientists with the University of Florida have found that a combination of silver nanoparticles and antibiotics is effective against antibiotic-resistant bacteria.

The researchers hope to turn this discovery into viable treatment for some types of antibiotic-resistant infections. Antibiotic-resistant infections kill more than a million people globally each year.

For centuries, silver has been known to have antimicrobial properties. However, silver nanoparticles—microscopic spheres of silver small enough to operate at the cellular level—represent a new frontier in using the precious metal to fight bacteria.

In this study, the research team tested whether commercially available silver nanoparticles boost the power of antibiotics and enable these drugs to counter the very bacteria that have evolved to withstand them.

Metastatic Embolus From Breast Adenocarcinoma In The Lungs

Metastatic embolus from breast adenocarcinoma in the lungs

cancer cells are usually very metamorphic, which you can tell by the different shapes of the nuclei in this embolus. i love how you can see the metastasis inside a vessel perfectly in this picture!

not to be positive on main but sometimes things really are ok. sometimes you really will be happy and safe and warm. sometimes you really will be giggly and blushy and full of love. sometimes the night is chilly and your home is cozy and your tea is perfectly steeped and your phone lights up with a message from someone you love. sometimes life really is quite lovely.

Hey... What The Fuck???
Hey... What The Fuck???

Hey... what the fuck???

So I read the article, and this is super cool. Basically what happened is that they let a drop of butyl alcohol out from a syringe onto the surface of another liquid, and it just... hung out there? For a very significant amount of time, too. In the past, this type of "droplet levitation" has only lasted a few milliseconds max, but this droplet was staying levitated without any external forces applied for tens of minutes.

The reason this happens is because of Solutocapilllary convection, which as far as I can tell essentially boosts the surface tension of that one spot in the underlying liquid using vapor molecules, so that the butyl alcohol molecule can't sink in.

Also, the reason why I specified that the reason this was cool is because it was done without external forces is that APPARENTLY we've been able to levitate things using sound waves since like... the 1930s. And it makes sense that you can do that, in principle, but it still looks absolutely wild to see.
