Cases of patients who recovered from trauma after dreaming under surgical anesthesia spur Stanford Medicine researchers to investigate dreaming as therapy.
A new study by Brown University researchers suggests that gold nanoparticles—microscopic bits of gold thousands of times thinner than a human hair—might one day be used to help restore vision in people with macular degeneration and other retinal disorders.
In a study published in the journal ACS Nano, the research team showed that nanoparticles injected into the retina can successfully stimulate the visual system and restore vision in mice with retinal disorders. The findings suggest that a new type of visual prosthesis system in which nanoparticles, used in combination with a small laser device worn in a pair of glasses or goggles, might one day help people with retinal disorders to see again.
“This is a new type of retinal prosthesis that has the potential to restore vision lost to retinal degeneration without requiring any kind of complicated surgery or genetic modification,” said Jiarui Nie, a postdoctoral researcher at the National Institutes of Health who led the research while completing her Ph.D. at Brown. “We believe this technique could potentially transform treatment paradigms for retinal degenerative conditions.”
In around a period of 30 minutes the United States can launch over 1,000 nuclear weapons against its enemies. This video is a realtime simulation of such an action.

Listening to favorite music activates the brain’s opioid system, which is involved in feelings of pleasure and pain relief, according to a new PET imaging study.
Computers that use photons rather than electrons to manipulate data promise greater speed and energy efficiency, and the technology is developing rapidly
Sound doesn’t just enter your ears – it may actually talk to your cells. New research out of Kyoto University shows that acoustic waves, even those in the audible range, can alter cellular behavior. Using specially designed equipment, scientists found that sound can suppress the formation of fat ce
Brain scans analyzed with AI reveal how narcissistic and Machiavellian traits align with different brain networks.

We still don’t know what “consciousness” actually means. But in a new study, researchers have used the equations of quantum mechanics to determine a brain’s “criticality,” a measure which allows them to separate waking brains from sleeping ones. I think they’re onto something. Let’s take a look.
