Cell proliferation is regulated by cyclin-dependent kinases (Cdks) and requires the periodic expression of particular gene clusters in different cell cycle phases. However, the interplay between the ...

Using the Hard X-ray Modulation Telescope (HXMT), Chinese astronomers have observed an X-ray binary system designated IGR J19294+1816. As a result, they discovered multiple X-ray quasi-periodic ...

It can be tempting to think of the stars that light up the sky each night as timeless. Astronomy professor John Thorstensen knows better. He has spent the last four decades studying cataclysmic binary ...

Researchers successfully observed petahertz (PHz: 1015 of a hertz) electron oscillation. The periodic electron oscillations of 667-383 attoseconds (as: 10-18 of a second) is the fastest that has ever ...

Ocean-atmosphere oscillations are naturally occurring cycles affecting sea surface temperature and precipitation. They are among the key reasons why some years are dry and plagued by drought while ...
