Phys.org / New way to harness copper makes antibiotic-resistant bacteria and cancer cells more vulnerable

University of Missouri researchers have discovered a new way to harness one of the body's natural defenses: copper. While copper is essential for life and helps power important biological processes, having too much of it ...

Phys.org / Hubble and Webb find that far-out solar system objects 'remember' the past

For the first time, scientists used the combined power of NASA's Hubble and James Webb Space Telescopes to study some of the most far-flung bodies in our solar system, trans-Neptunian objects (TNOs). Some are the smallest ...

Phys.org / A photon that challenges Einstein: According to current physics, it should never have reached Earth

How did a photon survive a journey of more than 2 billion light-years when, according to known physics, it should have been absorbed long before reaching Earth? This is the question at the heart of a new study by Giorgio ...
