Secret Link Uncovered Between Pure Math and Physics

December 1, 2017

An eminent mathematician reveals that his advances in the study of millennia-old mathematical questions owe to concepts derived from physics.


How Bacteria Help Regulate Blood Pressure

November 30, 2017

Kidneys sniff out signals from gut bacteria for cues to lower blood pressure after meals. Our understanding of how the symbiotic microbes affect health is becoming much more molecular.


Choosy Eggs May Pick Sperm for Their Genes, Defying Mendel’s Law

November 15, 2017

The oldest law of genetics says that gametes combine randomly, but experiments hint that sometimes eggs select sperm actively for their genetic assets.
