RNA Brakes May Stabilize a Cellular Symbiosis
...was not involved in the study. Even though mutualistic relationships benefit both parties, it’s wrong to think of them as inherently stable, said Thomas Richards, a professor of evolutionary genomics...
Physicists Identify the Engine Powering Black Hole Energy Beams
...normal evolution” — the plasma swirls around the black hole like water around a drain, and weak, randomly oriented, fluctuating magnetic field lines swirl with it. The turbulence of the...
Eve Marder on the Crucial Resilience of Neurons
...work. So, biology has to be able to tolerate diversity, and that probably it uses diversity in all kinds of ways as grist for evolution. Marder: Right. Exactly. So, that’s...
Scientists Catch Jumping Genes Rewiring Genomes
...of sites throughout the genome simultaneously; it’s hard to picture how natural selection enables that to happen. The answer may hold the key to understanding how complex evolutionary novelties such...
DNA’s Histone Spools Hint at How Complex Cells Evolved
New work shows that histones, long treated as boring spools for DNA, sit at the center of the origin story of eukaryotes and continue to play important roles in evolution...
Amie Wilkinson Sees the Dynamic Chaos in Puff Pastry
...as being the evolution of time, then you can address a question like, “Given the current configuration of our solar system, how long will it take until Mercury goes retrograde?”...
A Backdoor Lets the Immune System Monitor the Brain
...have identified how evolution achieves a balancing act, limiting the dangers of immune responses in the central nervous system while still providing protection from disease. The researchers reported recently in...
DNA of Giant ‘Corpse Flower’ Parasite Surprises Biologists
...and weigh a whopping 10 kilograms, roughly the heft of a toddler. More than a decade ago, Rafflesiaceae parasites caught the eye of Jeanmaire Molina, an evolutionary plant biologist at...
The New Historian of the Smash That Made the Himalayas
