Breakthrough DNA Editor Born of Bacteria
...of viruses. “And then the whole thing clicked,” said Eugene Koonin. At the time, Koonin, an evolutionary biologist at the National Center for Biotechnology Information in Bethesda, Md., had been...
Quantum Computing Without Qubits
...analog quantum computing with optical lattices and cold atom traps. What are the main challenges for these quantum simulators? Because the evolution of the analog simulation is not digitized, the...
Scientists Conjure Curves From Flatness
...5-7 pairs in many biological systems is the result of evolution or pure mechanics. “The funny thing is that the plant does it automatically,” Rivier said. “You cannot cut the...
New Twist Found in the Story of Life’s Start
...of sequences — including its own. And it’s still getting better. The ribozyme in the paper emerged after just 16 rounds of evolution, a shockingly short run for this kind...
Multiverse Collisions May Dot the Sky
...“But I think that’s the wrong way to think about it.” The theory of evolution, Peiris argues, also resembles a tautology in certain respects — “an organism exists because it...
Elusive Form of Evolution Seen in Spiders
...puzzle to evolutionary biologists. According to ordinary Darwinian natural selection, only the fittest individuals will pass on their genes. But if that’s the case, why do tangle-web spiders act in...
Finding Dark Energy in the Details
...then we can say, “Do we live in this kind of universe, or this kind?” What do the data so far tell us about wa? They’re consistent with no evolution...
Evolution’s Random Paths Lead to One Place
...uses statistical methods to study basic questions in evolution. Many biologists argue that it would not, that chance mutations early in the evolutionary journey of a species will profoundly influence...
A Brazilian Wunderkind Who Calms Chaos
...and is basically unstoppable.” Avila has also studied the evolution of quantum states in physical systems governed by “quasi-periodic Schrödinger operators,” which are crude models for quasicrystals, structures that have...
