Cori Bargmann on the Genetics of Transparent Worms, Supertasters and Cancer
...is there such a thing as — over evolutionary times — just getting genes going — what’s the word — like, going defunct, because they’re not getting used anymore? Bargmann:...
Axions Would Solve Another Major Problem in Physics
...thought about the rotating axion field and the cyclical evolution of θ, “we realized that the rest of it is almost automatic,” Co said. “We just do the computation to...
Machine Learning Takes On Antibiotic Resistance
...much more effective.” To this end, they use computer models to quickly simulate evolutionary changes, including the effects of mutation, selection and genetic recombination, with feedback loops of that sequence...
Biodiversity May Thrive Through Games of Rock-Paper-Scissors
...Darwin’s initial work confirmed that competition is indeed a major evolutionary force. There is just one problem. If simplistic competition were the only evolutionary force, then after billions of years,...
‘Radical Change’ Needed After Latest Neutron Star Collision
...aspects of binary star evolution are poorly understood, including how the stars exchange mass and get close enough to merge. “We know a great deal about stellar formation and evolution,...
New Clues About ‘Ambigram’ Viruses With Strange Reversible Genes
...California point to an unexpected answer. The ambigrammatic property of narnaviruses may be a clever mechanism of self-preservation, one that could significantly expand the picture of viral evolution and suggest...
Immune Cell Assassins Reveal Their Nurturing Side
...it up. Metchnikoff didn’t immediately assume that these phagocytes are specialized for disease fighting and pathogen removal alone. Trained as an evolutionary biologist, he knew that simple organisms generally had...
Did the Chicken Come First or Is It Turtles All the Way Down?
...others are more whimsical and subjective, but hopefully all will be illuminating. In biology, the problem of infinite regress has been solved by Darwin’s theory of evolution, a feat so...
Secrets of Math From the Bee Whisperer
...insight into the evolution of numerical ability. Is this evolution divergent? Convergent? Parallel? There is a big debate about numerical ability in animals. One side argues that numerical cognition —...
