Phys.org / A new nuclear 'island' where magic numbers break down

For decades, nuclear physicists believed that "Islands of Inversion"—regions where the normal rules of nuclear structure suddenly break down—were found mostly in neutron-rich isotopes. In these unusual pockets of the ...

Phys.org / Engineering analysis of Thrinaxodon fossils uncovers unexpectedly advanced hearing in early mammal kin

One of the most important steps in the evolution of modern mammals was the development of highly sensitive hearing. The middle ear of mammals, with an eardrum and several small bones, allows us to hear a broad range of frequencies ...

Phys.org / Bacterium's molecular speargun defense may leave it exposed to antibiotics

Countless bacterial species share cramped environments where competition for space and resources is fierce. Some rely on a molecular speargun to outcompete their opponents. One of them is Pseudomonas aeruginosa. It is widespread ...
