Scientists at UC Davis discovered a small genetic difference that could explain why humans are more prone to certain cancers than our primate cousins. The change affects a protein used by immune cells to kill tumors—except in humans, it’s vulnerable to being shut down by an enzyme that tumors release. This flaw may be one reason treatments like CAR-T don’t work as well on solid tumors. The surprising twist? That mutation might have helped our brains grow larger over time. Now, researchers are exploring ways to block the enzyme and give our immune system its power back.

Good call, I should have worded that better. While the government and scientists were instrumental in creating the foundation for the internet, I was thinking more along the lines of the early PC era. When the internet was more or less a tool for openly sharing and discussing information as well as ideas.

But a lot of tech stems from governmental need and/or government funding. I mean, the modern refrigerator was a result of NASA problem solving for the environmental conditions found in space! GPS, LASIK, MRI's, LED's, barcodes, closed captioning, and the human genome project were all also thanks to government research too!

Without Google's grubby paws across most the web, it'd be much more like the initial intent of what the internet was supposed to be, a welcoming place with open and accessible info!

If you don't want to pay to access a web search service, just use docker and run your own SearXNG instance! This will also allow you to host our own AI model that searches the web through SearXNG. While it may sound like a lot of work, it truly takes an afternoon and some unused RAM on your PC to make happen, then you're set up!

 

In a surprising twist during an air quality study in Oklahoma, researchers detected MCCPs an industrial pollutant never before measured in the Western Hemisphere's atmosphere. The team suspects these toxic compounds are entering the air through biosolid fertilizers derived from sewage sludge. While these pollutants are not yet regulated like their SCCP cousins, their similarity to dangerous "forever chemicals" and unexpected presence raise red flags about how chemical substitutions and waste disposal may be silently contaminating rural air.

 

Scientists have discovered a unique class of small antibodies that are strongly protective against a wide range of SARS coronaviruses, including SARS-CoV-1 and numerous early and recent SARS-CoV-2 variants. The unique antibodies target an essential highly conserved site at the base of the virus’s spike protein, effectively clamping it shut and preventing the virus from infecting cells. The findings, published in Nature Communications, offer a promising route to developing broad-spectrum antiviral treatments that could remain effective against future viral variants.
