UCLA researchers have discovered that some scar-forming cells in the heart, known as fibroblasts, have the ability to become endothelial cells — the cells that form blood vessels. The finding could point the way toward a new strategy for treating people who have suffered a heart attack, because increasing the number of blood vessels in the heart boosts its ability to heal after injury.
By the time of her death in 1458 B.C., Egypt’s Pharaoh Hatshepsut had presided over her kingdom’s most peaceful and prosperous period in generations. Yet by 25 years later, much of the evidence of her success had been erased or reassigned to her male forbears.
The amazing advances made in mapping the human genome don’t alter one longstanding fact: When it comes to unlocking the scientific secrets of life, fruit flies rule.
Amy Rowat, an assistant professor at UCLA’s Department of Integrative Biology and Physiology, believes food can be a powerful way to communicate science to a broad audience.
William Marotti couldn’t believe his good fortune when he was hired in 2006 by UCLA’s history department.
Many collisions occur between asteroids and other objects in our solar system, but scientists are not always able to detect or track these impacts from Earth. The “rogue debris” created by such collisions can sometimes catch us by surprise.
Like finally seeing all the gears of a watch and how they work together, researchers from UCLA and UC Berkeley have, for the first time ever, solved the puzzle of how the various components of an entire telomerase enzyme complex fit together and function in a three-dimensional structure.
Baboons whose mothers have strong relationships with other females are more likely to survive to adulthood than those with less social mothers, according to a new study by UCLA researchers and colleagues.
A new picture of the early Earth is emerging, including the surprising finding that plate tectonics may have started more than 4 billion years ago â€” much earlier than scientists had believed.
