Age isn't just a number for one of the ocean's top apex predators. It's a mystery University of Georgia researchers are solving. A new UGA study has determined how to estimate the age of sharks by analyzing changes to individual ...
Young Bewick's swans only survive their first spring migration if they stay with their parents long enough. If they lose their parents in winter, they leave later and are unable to keep up with the rest of the population. ...
In just a few short years, generative artificial intelligence tools have made a leap from novelties that produce stilted text to genuine societal disruptors that may alter the way people learn, work and even think.
A University of Staffordshire Ph.D. student has received national recognition for research that could transform how bloodstain evidence at crime scenes is analyzed. Emma Hook has been awarded the Science & Justice Review ...
Jennifer Bhatnagar spent the summer of 2023 traversing barren hillsides blackened by wildfire in northern California. She walked through devastated properties, examined the hot soil beneath her feet, collected samples and ...
All living things have a fleet of tiny copy machines that turn instructions from DNA into RNA molecules responsible for helping build proteins that keep organisms alive. One of those nanoscale machines, called eukaryotic ...
Neanderthals are largely associated with colder climates across Eurasia. But researchers know that both Homo sapiens and Neanderthals moved through nearby Southwest Asia between about 100,000 and 50,000 years ago, and Arabia ...
100 million years ago, long before human intervention, ancestors of grasses, including wheat, rice and maize, developed "bypasses" in chemical pathways used to create two critical compounds: lignin and starch. These more ...
Nearly every cell in the human body contains essentially the same genetic information, yet different cells activate different genes. For regulatory proteins to reach these genes, DNA must be accessible. This accessibility ...
It's one of the origins-of-life chicken-or-egg problems: How could RNA have helped give rise to the first cells before there were cells to contain it?
