Preying on hungry, anxious worms

LA JOLLA—The life of the tiny worm called Caenorhabditis elegans consists mostly of looking for food, eating food, and laying eggs. So, when any of these behaviors are disrupted, there’s …


Salk Institute promotes five faculty members in genetics, structural biology, immunobiology, and neuroscience

LA JOLLA—Five Salk Institute faculty members have been promoted for their notable, innovative contributions to science. These faculty members have demonstrated leadership in their disciplines, pushing the boundaries of basic …


Why hungry worms take risks

LA JOLLA–Whether it’s making rash decisions or feeling grumpy, hunger can make us think and act differently—“hangry,” even. But little …


Tiny worms make complex decisions, too

LA JOLLA—How does an animal make decisions? Scientists have spent decades trying to answer this question by focusing on the cells and connections of the brain that might be involved. …


In a first for “sonogenetics,” researchers control mammalian cells with sound

LA JOLLA—Salk scientists have engineered mammalian cells to be activated using ultrasound. The method, which the team used to activate human cells in a dish and brain cells inside living …


Reading the mind of a worm

LA JOLLA—It sounds like a party trick: scientists can now look at the brain activity of a tiny worm and tell you which chemical the animal smelled a few seconds …


Salk’s Sreekanth Chalasani wins 2021 NPA Gallagher Mentor Award

LA JOLLA—Salk Associate Professor Sreekanth Chalasani has won the 2021 National Postdoctoral Association (NPA) Gallagher Mentor Award. The announcement was made at the 2021 NPA Annual Conference, which took place …


Salk neuroscientists receive $4.4 million from NIH BRAIN Initiative

LA JOLLA—Salk Institute neuroscientists Edward Callaway, Sreekanth Chalasani, and Nancy Padilla Coreano have been named recipients in the 2020 round of grants from the National Institutes of Health (NIH) to …


Salk scientists advance ultrasound technology for neurological therapy

LA JOLLA—The emerging technology of sonogenetics—a technique where cells are controlled by sound—offers the potential to one day replace pharmaceutical drugs or invasive surgical treatments for neurological conditions like epilepsy, …


Decoding the chemistry of fear

LA JOLLA—Ask a dozen people about their greatest fears, and you’ll likely get a dozen different responses. That, along with the complexity of the human brain, makes fear—and its close …


Worms have teenage ambivalence, too

LA JOLLA—Anyone who has allowed a child to “help” with a project quickly learns that kids, no matter how intelligent or eager, are less competent than adults. Teenagers are more …


Salk neuroscientist granted $1 million to harness sound to control brain cells

LA JOLLA—Salk Associate Professor Sreekanth Chalasani has been awarded a grant from the National Institutes of Health’s (NIH) Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative for developing a way …


Salk promotes four leading scientists in the fields of neuroscience, circadian rhythms and immunology

LA JOLLA–Four Salk Institute faculty members have been promoted after the latest round of faculty reviews determined they are scientific leaders who have made original, innovative and notable contributions to …


Can your sense of smell predict when you’ll die?

LA JOLLA–By measuring how worms move toward an appealing, food-like scent, researchers at the Salk Institute were able to predict whether the worms would be long-lived. The finding, published September …


In first, Salk scientists use sound waves to control brain cells

LA JOLLA–Salk scientists have developed a new way to selectively activate brain, heart, muscle and other cells using ultrasonic waves. The new technique, dubbed sonogenetics, has some similarities to the …


How the brain balances risk-taking and learning

LA JOLLA–If you had 10 chances to roll a die, would you rather be guaranteed to receive $5 for every roll ($50 total) or take the risk of winning $100 …


Worms’ mental GPS helps them find food

LA JOLLA–You’ve misplaced your cell phone. You start by scanning where you remember leaving it: on your bureau. You check and double-check the bureau before expanding your search around and …


Insulin plays a role in mediating worms’ perceptions and behaviors

LA JOLLA,CA—In the past few years, as imaging tools and techniques have improved, scientists have been working tirelessly to build a detailed map of neural connections in the human brain—with …
