Strength in numbers: Physicists identify new quantum state allowing three -- but not two -- atoms to stick together
(Phys.org) -- A Kansas State University-led quantum mechanics study has discovered a new bound state in atoms that may help scientists better understand matter and its composition.
Why some grasses evolved a more efficient photosynthesis and others didn't
Even on the evolutionary time scale of tens of millions of years there is such a thing as being in the right shape at the right time. An anatomical difference in the ability to seize the moment, according ...
