Biologists Invoke the Past in Modern Bacteria
...study the evolution of the whole complex network that surrounds the EF-Tu hub. “When we think about evolution, we tend to think about it at the level of the organism,...
The Fuzzball Fix for a Black Hole Paradox
...hole information paradox. The Horizon Problem Mathur’s fuzzball conjecture owes its evolution to his longstanding fascination with this paradox, another consequence of Hawking radiation. Hawking noted that according to quantum...
Decoding the Remarkable Algorithms of Ants
...thought of yet. I am interested in the idea that evolution might produce different algorithms in different systems to solve the same problems. But for evolution to produce algorithms that...
Why the Big Bang’s Light May Have a Tilt
...found to be true. “It’s not all that powerful to predict something you already know,” he said. Spectral measurements could also provide insight into the evolution of the universe at...
Can Information Rise From Randomness?
...are. To coin a classically mixed neologism, we are Homo enigmatus — in more ways than one. Evolution has made us cognitive beings by giving us small internal rewards whenever...
New Letters Added to the Genetic Alphabet
...Benner, an organic chemist at the Foundation for Applied Molecular Evolution in Florida. Nearly 30 years ago, Benner sketched out better versions of both DNA and its chemical cousin RNA,...
How Life and Luck Changed Earth’s Minerals
Is evolution predictable, or was it heavily shaped by random events? Biologists have argued over this question for decades. Some have suggested that if we replayed the history of life...
A Surprise Source of Life’s Code
...existence,” said David Begun, a biologist at the University of California, Davis. New genes appear to burst into existence at various points along the evolutionary history of the mouse lineage...
How Mutant Viral Swarms Spread Disease
...closely related viruses. This viral genetic jumble has given Marco Vignuzzi, a virologist at the Pasteur Institute in Paris, a way to predict the future evolution of RNA viruses like...
