Her death is a reminder that antibiotic-resistant bacteria are getting worse, even as they garner little attention.

Senescent cell therapy for treating age-related diseases could also help people after chemotherapy.
Senescent cell removal therapies could help reduce the damaging impact chemotherapy has on patients as well as being used to address one of the aging processes to treat diseases.

Most of today’s robot hands can perform easy tasks. They’re uber-practical grippers, simple and useful. But is it really so much to ask for robotic masterworks as dextrous as Luke Skywalker’s bionic hand in Star Wars? In short, yes, yes it is. It might have been a long time ago in a galaxy far far away—but most Star Wars tech is beyond us.
Still, it’s hard not to get in a Star Wars state of mind watching this beautiful robot hand engineered by Yale postdoc Joseph (Zhe) Xu and the University of Washington’s Emanuel Todorov.

The last of the fun videos about the immune system and how it works.
THE FINAL SHOWDOWN! This is the last episode on the immune system and also the very last episode of Crash Course Anatomy & Physiology. In it, Hank explains how the cellular immune response uses helper, cytotoxic, and regulatory T cells to attack body cells compromised by pathogens. He also explores how cytokines activate B and T cells, and what happens if your immune system goes rogue and starts causing autoimmune trouble.

It’s the stuff of Chemistry 101: carbon can only form four bonds because it only has four shareable electrons.
But this rule no longer applies, because scientists have confirmed the existence of an exotic carbon molecule that can form six bonds, meaning the most classic example of tetravalence in our high school chemistry textbooks now comes with a hefty caveat.
If all of this is kinda giving you conniptions, we’re right there with you.

Looks like hacking might be alot older then we thought lmao.
Biologists at UC San Diego have documented for the first time how very large viruses reprogram the cellular machinery of bacteria during infection to more closely resemble an animal or human cell—a process that allows these alien invaders to trick cells into producing hundreds of new viruses, which eventually explode from and kill the cells they infect.
In a paper published in the January 13 issue of Science, the researchers conducted a series of experiments that allowed them to view in detail what happens inside bacterial cells as the invading viruses replicate.
“Scientists have been studying viruses for a hundred years, but we’ve never seen anything like this before,” said Joe Pogliano, a professor of molecular biology who headed the research team. “Every experiment produced something new and exciting about this system.”
