Why lung cancer doesn’t respond well to immunotherapy

A new study reveals that the immune system mounts a weak response to lung cancer due to an environment created by bacteria in the lymph nodes near the lungs. T-cell responses are suppressed by regulatory T cells and interferon gamma produced in response to commensal bacterial presence.

Genes decide the willow warbler’s migration routes

Researchers at Lund University identified two areas in the genome that decide whether a willow warbler migrates across the Iberian Peninsula or the Balkans. This discovery sheds light on the genetics behind songbirds' migratory behaviour and has implications for understanding how species adapt to climate change.

Invention: A blood test to unlock prostate cancer mysteries

Researchers at Cedars-Sinai Cancer have developed a non-invasive test that can detect and profile prostate cancers in microscopic amounts.

This breakthrough facilitates cancer research for complex tumors and opens new directions for drug target discovery.

Robot: I'm sorry. Human: I don't care anymore!

A University of Michigan study found that humans are less forgiving of robots after multiple mistakes and that trust is difficult to get back. The researchers tested four repair strategies, but none were able to fully restore trust after three violations.

Unconventional superconductivity found in kagome metal

Physicists at Paul Scherrer Institute have found a way to tune the temperature of an unusual type of superconductor. By applying pressure, they were able to change the characteristics of the superconductivity from a 'nodal' structure to a 'nodeless' one, opening up possibilities for engineering quantum materials.
