Key Highlights
•
Researchers discovered a shared molecular switch, involving a protein called ANKIB1, that turns on powerful immune defenses against viruses and in certain autoimmune diseases. This finding reveals a common root for different immune triggers, opening new paths for treating conditions like herpes and interferonopathies.

Scientists have developed a new method, called Optovolution, that uses light to rapidly evolve proteins with complex new abilities, like acting as light-responsive switches or biological logic gates. This breakthrough makes it possible to engineer sophisticated protein behaviors that were previously too difficult to create through evolution.

The common diabetes drug metformin has been repurposed to fight antibiotic-resistant E. coli infections in cows by breaking down bacterial biofilms and calming the host’s harmful inflammation. This dual-action strategy offers a promising non-antibiotic approach to tackle tough infections in agriculture and potentially human medicine.

A study shows that in aggressive pancreatic cancers driven by the MYC gene, cancer cells become dependent on a nutrient-sensing protein called MondoA to survive and grow. This reveals a critical vulnerability that could be targeted with new drugs to treat these difficult cancers.

Scientists found that a cholesterol-related signal, detected by a receptor called GPR183 on immune cells, guides new monocytes to settle and become lung macrophages when resident cells are lost. This discovery identifies a key chemical cue that instructs the body’s immune system to repopulate vital tissue sentinels.
