Scientists have gained insights into the weak nuclear force from new, more sensitive studies of the beta decays of the 'mirror' nuclei lithium-8 and boron-8. The weak nuclear force drives the ...
Astronomers have discovered ultra-weak magnetic fields in Beta Ursae Majoris and Theta Leonis, two metallic-line stars. Obtained from deep spectropolarimetric analysis, the results may be proof ...
