New tools filter noise from evolution data
While rates of evolution have appeared to accelerate over short time periods, new analysis suggests that statistical noise is affecting the data patterns. A professor at the University of Tennessee, Knoxville, and his colleague ...

First successful test of wild minke whales reveals they have ultrasonic hearing
A team of marine biologists from Norway, the U.S. and Denmark has conducted the first hearing test of a live baleen whale. For their study published in the journal Science, the group corralled a pair of wild minke whales ...
New maps show high-risk zones for whale-ship collisions—vessel speed limits and rerouting can reduce the toll
Imagine you are a blue whale swimming up the California coast, as you do every spring. You are searching for krill in the Santa Barbara Channel, a zone that teems with fish, kelp forests, seagrass beds and other undersea ...

Gene regulation study reports surprising results: Extensive regions of DNA belong to multiple gene switches
Some sequences in the genome cause genes to be switched on or off. Until now, each of these gene switches, or so-called enhancers, was thought to have its own place on the DNA. Different enhancers are therefore separated ...

'e-Drive': New gene drive reverses insecticide resistance in pests... then disappears
Insecticides have been used for centuries to counteract widespread pest damage to valuable food crops. Eventually, over time, beetles, moths, flies and other insects develop genetic mutations that render the insecticide chemicals ...

Parasaurolophus pipes: Modeling the dinosaur's crest to study its sound
Fossils might give a good image of what dinosaurs looked like, but they can also teach scientists what they sounded like. The Parasaurolophus is a duck-billed dinosaur with a unique crest that lived 70 million to 80 million ...

tRNAs help some mRNAs get lost in translation
Scientists have discovered that tRNAs can determine how long mRNAs exist in a cell, causing some messages to be stabilized and translated into more protein, while directing others to be degraded and limiting how much protein ...

AI and genus-conditioned algorithms create precise simulation-ready models of 600,000 existing urban trees
The Irish philosopher George Berkely, best known for his theory of immaterialism, once famously mused, "If a tree falls in a forest and no one is around to hear it, does it make a sound?" What about AI-generated trees? They ...
