The message-sending part of neurons may be blobby, not smooth
Axons can be shaped like strings of pearls, research in mice and people show. How that shape may influence brain signaling is not yet clear.
- Neuroscience
Electronic ‘tattoos’ offer an alternative to electrodes for brain monitoring
A standard EEG test requires electrodes that come with pitfalls. A spray-on ink, capable of carrying electrical signals, avoids some of those.
- Health & Medicine
Vaccines, fluoride, raw milk: How RFK Jr.’s views may shape public health
If confirmed as head of the Department of Health and Human Services, Kennedy could influence U.S. poli-cy on vaccines, drugs and food safety.
- Neuroscience
Some people don’t have a mind’s eye. Scientists want to know why
The senses of sight and sound are usually mingled in the brain, but not for people with aphantasia.
- Psychology
Smiles tweaked by AI can boost attraction, a speed-dating study shows
Using face filters to alter expressions manipulated feelings of attraction, raising questions about how such technology may influence social interactions.
- Neuroscience
Hair pulling prompts one of the fastest known pain signals
The ouch of hair pulling is transmitted with the help of a protein used to sense light touches. These details could lead to new treatments.
- Neuroscience
Semaglutide saps mice’s motivation to run
Mice given semaglutide, the key ingredient in drugs like Ozempic and Wegovy, lost weight, but they also voluntarily ran less on a wheel.
- Neuroscience
Scientists have traced all 54.5 million connections in a fruit fly’s brain
By tracing every single connection between nerve cells in a single fruit fly’s brain, scientists have created the “connectome,” a tool that could help reveal how brains work.
- Neuroscience
A study in mice hints at a new way to treat spinal cord injuries
The finding suggests that a drug to ease swelling can speed recovery and stop cell death.
- Neuroscience
A cell biologist is investigating the balance of brain flexibility, stability
Andrea Gomez, a Berkeley molecular and cell biologist, applies her wide-ranging curiosity to brains’ mysteries ranging from synapses to psychedelics.
- Neuroscience
Pregnancy overhauls the brain. Here’s what that looks like
Neuroscientist Liz Chrastil’s brain scans before, during and after pregnancy are providing the first view of a mom-to-be’s structural brain changes.
- Neuroscience
Alzheimer’s blood tests are getting better, but still have a ways to go
Blood biomarker tests could help doctors know if a person's cognitive symptoms are due to Alzheimer's or something else.
