Nucleus

Atomic clocks are our most accurate timekeepers, losing only seconds across billions of years. But nuclear clocks could steal their thunder, speeding up GPS and the internet. Now, scientists have built and tested the first prototype nuclear clock.

Physicists have created the heaviest clumps of antimatter particles ever seen. Known as antihyperhydrogen-4, this strange stuff could help us solve some of the most puzzling physics mysteries.

Scientists have uncovered hints of a world of new elements beyond the periodic table. A new study has found that ancient stars may have been producing extremely heavy elements that remain unknown to science.

Perovskites are quickly emerging in the solar energy field, thanks to their ability to convert photons into electricity. Now this process has been tweaked to pick up neutrons instead, making an effective detector for leaks from radioactive materials.

One of the most frustrating things about exercise is how easily progress can be undone, but maybe not all is lost after all. Researchers have now found that muscles keep their nuclei from past growth, which makes it easier to rebuild later after a period of inactivity.

An international team of scientists using the largest telescope in the world at Keck Observatory has overcome a major obstacle to the Big Bang model of the Universe.
