How does conflict spread? (stock image) Credit: © Alexey Astakhov / Fotolia How does conflict spread through a society? One way to think of conflict spreading is to picture an epidemic, with aggressive individuals “infecting” others and causing them to join the fight. While studying the dynamics of conflict in a monkey society, researchers Edward

Fruit flies’ mitochondria (in green) at 10 days (top left), 28 days (top right) and 37 days old (both bottom images). At bottom right, the mitochondria have returned to a more youthful state after UCLA biologists increased the fly’s level of a protein called Drp1.

Discovering paths the chemicals of life likely took on Earth could make it possible to calculate probabilities of life on other planets. Credit: NASA/Ames/JPL-Caltech The primordial soup that sloshed around billions of years ago, and eventually led to first life on our planet, might have been teeming with primal precursors of proteins. Ancestors of the

Brain cancer stem cells (left) are killed by Zika virus infection (image at right shows cells after Zika treatment). A new study shows that the virus, known for killing cells in the brains of developing fetuses, could be redirected to destroy the kind of brain cancer cells that are most likely to be resistant to

Dogs have the ability to recognize themselves, research shows.

The experiment

The results are published in the journal Nature Climate Change this week (Monday 4

The skull of a 250 million year old fossil fish and a virtual model of its internal skeleton, along with a life reconstruction. Credit: Andrey Atuchin Polypterids are weird and puzzling African fish that have perplexed biologists since they were discovered during Napoleon’s expedition to Egypt in the late 1700s. Often called living fossils, these

For clues into how Myrmoteras executes its power-amplified strike, scientists examined the ants first under a microscope, then using micro computed tomography (micro-CT), a three-dimensional imaging system that uses X-rays to visualize the internal structures of small specimens. Their observations allowed them to piece together a model of how the jaws likely works. Researchers detected

This is an orange clownfish, Amphiprion percula, living in symbiosis with a host anemone.
