Phys.org / Ancient DNA sequences that control gene function across plant evolution uncovered
A study has traced thousands of conserved regulatory elements back 300 million years, revealing deep principles of plant genome evolution—a discovery that could pave the way for more precise engineering of crop traits.
Phys.org / Nocturnal ants use lunar compass and sophisticated calculations to travel at night
It's well known that many animals, including migratory birds, butterflies, and even fish, use the sun for navigational purposes. Nocturnal animals are dealt a more difficult hand, however, as the moon's path is far more variable. ...
Medical Xpress / Calcium signaling channels regulate neuroinflammation and motivation, research reveals
Northwestern Medicine scientists have discovered how calcium signaling channels in microglia—the primary immune cells of the brain—regulate neuroinflammation and promote the development of behaviors associated with affective ...
Phys.org / Embryogenesis in 4D: A developmental atlas for genes and cells
How does a tiny cluster of cells become an embryo with a head, trunk, and tail? And how do thousands of genes coordinate this development? A new imaging method makes it possible to visualize the activity of thousands of genes ...
Medical Xpress / Scientists find a new therapeutic target present on up to half of all tumors
For five decades, scientists have known about a notorious cancer-causing enzyme called SRC. But they always assumed it only appeared on the inside of cells, where it sent signals that fueled tumor growth and stayed hidden ...
Phys.org / The power of twins: Decoding the unseen biological information flow
The natural world is a rich source of inspiration for developing sophisticated computational systems, and the opposite is also true, with bioinformatics approaches providing keen insight into biological processes. However, ...
Phys.org / Dolphin mass strandings in Patagonia linked to killer whales
In 2021 and 2023, hundreds of dolphins were stranded in shallow waters in San Antonio Bay in northern Patagonia. Some died, but many were returned safely to the sea. But what remained a mystery until now was how they ended ...
Medical Xpress / Tuning T cells' cancer-killing power via an engineered hydrogel platform
Lymph nodes, considered the command centers of our immune system, often get swollen and stiff when fighting infection. Now, a UC Berkeley-led team of researchers has discovered that this mechanical change may help instruct ...
Tech Xplore / 'Privacy by design': Tech protects against identity leaking during AI photo editing
Consumers, businesses, and institutions may soon have private, secure, and trustworthy generative AI tools for editing and sharing profile photos, ID images, and personal pictures without exposing their private identities ...
Medical Xpress / Watching a lifetime in motion reveals the architecture of aging
By midlife, an animal's everyday behaviors can signal how long it is likely to live. That is the striking conclusion of a new study in which researchers put scores of short-lived fish under continuous, lifelong surveillance ...
Phys.org / Astronomers discuss fortifying our planetary defenses
When people think of asteroids, they tend to picture rare, civilization-ending impacts like those depicted in movies such as "Armageddon." In reality, the asteroids most likely to affect modern society are much smaller. While ...
Phys.org / Hydrogen atmosphere could keep exomoons habitable for billions of years
Liquid water is considered essential for life. Surprisingly, however, stable conditions that are conducive to life could exist far from any sun. A research team from the Excellence Cluster ORIGINS at LMU and the Max Planck ...
