According to the World Health Organization, antibiotic resistance is a top public health risk that was responsible for 1.27 million deaths across the globe in 2019. When repeatedly exposed to antibiotics, bacteria rapidly learn to adapt their genes to counteract the drugs—and share the genetic tweaks with their peers—rendering the drugs ineffective.

Superpowered bacteria also torpedo medical procedures—surgery, chemotherapy, C-sections—adding risk to life-saving therapies. With antibiotic resistance on the rise, there are very few new drugs in development. While studies in petri dishes have zeroed in on potent candidates, some of these also harm the body’s cells, leading to severe side effects.

What if there’s a way to retain their bacteria-fighting ability, but with fewer side effects? This month, researchers used AI to reengineer a toxic antibiotic. They made thousands of variants and screened for the ones that maintained their bug-killing abilities without harming human cells.

Increasing serotonin can change how people learn from negative information, as well as improving how they respond to it, according to a new study published in the leading journal Nature Communications.

The study by scientists at the University of Oxford’s Department of Psychiatry and the National…


Serotonin is involved in aversive processing, but how serotonin shapes behavior remains unclear. Here, the authors show that directly enhancing synaptic serotonin in humans reduces outcome sensitivity and increases behavioral inhibition in aversive contexts.

Many believe humanity’s climb upward may have been assisted by outsiders. Is this possible, and if so, what does that tell us about our own past… and future?
