Cells Talk and Help One Another via Tiny Tube Networks
Long-overlooked “tunneling nanotubes” and other bridges between cells act as conduits for sharing RNA, proteins or even whole organelles.
How Many Genes Do Cells Need? Maybe Almost All of Them
An ambitious study in yeast shows that the health of cells depends on the highly intertwined effects of many genes, few of which can be deleted together without consequence.
Machine Learning’s ‘Amazing’ Ability to Predict Chaos
In new computer experiments, artificial-intelligence algorithms can tell the future of chaotic systems.
Decades-Old Graph Problem Yields to Amateur Mathematician
By making the first progress on the “chromatic number of the plane” problem in over 60 years, an anti-aging pundit has achieved mathematical immortality.
Ultra-Accurate Clocks Lead Search for New Laws of Physics
Atomic clocks are letting physicists tighten the lasso around elusive phenomena such as dark matter.
Trouble Detected in Infamous Dark Matter Signal
Independent scientists have cast serious doubt on a claimed detection of dark matter.
A Revealer of Secrets in the Data of Life and the Universe
The statistician Donald Richards lives to uncover subtle patterns hiding in real-world data.
The Elusive Calculus of Insects’ Altruism and Kin Selection
How the ultra-cooperative behavior of ants, bees and other social insects could have evolved continues to challenge formal analysis. But a new theory about hedging bets against nature’s unpredictability may change the math and shift the debate.
Mathematicians Explore Mirror Link Between Two Geometric Worlds
Decades after physicists happened upon a stunning mathematical coincidence, researchers are getting close to understanding the link between two seemingly unrelated geometric universes.
