New Research Debunks Myth That Brain Cells Stop Growing After Childhood

You’ve probably heard the old canard that new brain cells simply stop forming as we become adults. But research out today is the latest to show that this isn’t really true. Scientists in Sweden led the study, published Thursday in Science. They found abundant signs of neural stem cells growing in the hippocampus of adult brains. The findings reveal more about the human brain as we get older, the researchers say, and also hint at potential new ways to treat neurological disorders. “We’ve found

Serenading Cells with Audible Sound Alters Gene Activity

The cells in your ears aren’t the only ones listening: recent research suggests that crucial cells throughout the body may respond to audible sound. Experiments described in Communications Biology revealed more than 100 genes whose activity changed in response to these acoustic waves, pointing to possible medical applications. Extensive earlier research has shown that ultrasound—sound at frequencies higher than humans can hear—can affect biology in numerous ways; the new study expands this conc

Genesis AI launches with $105M seed funding from Eclipse, Khosla to build AI models for robots

Genesis AI, a startup that aims to build a foundational model for powering all kinds of robots, has emerged from stealth with a giant $105 million seed round co-led by Eclipse Ventures and Khosla Ventures. Founded last December by Zhou Xian (pictured above, left), a Ph.D. in robotics from Carnegie Mellon University, and Théophile Gervet, a former research scientist with the French AI lab Mistral, the startup wants to build a general-purpose model that will enable robots to automate a wide range

Genetic code enables zebrafish to mend damaged organs

Zebrafish have the remarkable and rare ability to regrow and repair their hearts after damage. New research from Caltech and UC Berkeley has identified the circuit of genes controlling this ability and offers clues about how a human heart might someday be repaired after damage, such as a heart attack or in cases of congenital heart defects. The research was a collaboration between the laboratories of Marianne Bronner, Caltech's Edward B. Lewis Professor of Biology and director of the Beckman In

Missing Heritability: Much More Than You Wanted to Know

The Story So Far The mid-20th century was the golden age of nurture. Psychoanalysis, behaviorism, and the spirit of the ‘60s convinced most experts that parents, peers, and propaganda were the most important causes of adult personality. Starting in the 1970s, the pendulum swung the other way. Twin studies shocked the world by demonstrating that most behavioral traits - including socially relevant traits like IQ - were substantially genetic. Typical estimates for adult IQ found it was about 60%

Virtual cells

Virtual cells Digital twins of biological cells—often referred to as virtual cells or whole-cell models (WCMs)–aim to recreate every relevant molecular process of a living cell in silico. This interdisciplinary endeavor marries systems biology, computational modeling, high-performance computing, and, increasingly, AI. All models are wrong, but some are alive. Somewhere in a data center right now, a virtual bacterium is dividing for the millionth time. Somewhere else, an AI-enhanced model is l

Disney Pinnacle unveils Genesis Keys quest with Web3 support from Dapper Labs

Disney Pinnacle by Dapper Labs, the digital pin collecting and trading platform, has now announced its Genesis Keys quest. That means Disney fans worldwide can claim free Genesis Keys every four hours as part of the global quest for one-of-one Genesis Editions — the first digital pins ever minted on the platform. The Genesis Keys campaign marks the first phase of Disney Pinnacle by Dapper Labs’ rollout gearing up for more action throughout the summer. As the community collectively claims Keys
