New way to control neurons with wireless and battery-free implant

New study reveals a more sophisticated method for delivering light to control neurons in the brain -- which could ultimately mean turning off pain...

Living cells can help create better encryption keys

Living cells, regardless of the type, can be kept around for a long time and because they move constantly, can be photographed repeatedly to...

Scientists create a safe, wearable soft sensor

The biocompatible sensor is made from a non-toxic, highly conductive liquid solution that could be used in diagnostics, therapeutics, human-computer interfaces, and virtual reality. Children...

Scientists create world’s smallest tic-tac-toe game board with DNA

Move over Mona Lisa, here comes tic-tac-toe. It was just about a year ago that Caltech scientists in the laboratory of Lulu Qian, assistant professor...

A new way to use gene editing tool CRISPR

Scientists have developed a method to use CRISPR/Cas9 technology to set off a cascade of activities in cells, a phenomenon known as conditional gene...
New tech could identify disease-fighting cells at high speed in high volumes

New tech could identify disease-fighting cells at high speed in high volumes

A new technology that identifies disease-related antigens and T cells that could potentially destroy them could speed the development of new therapies to treat...

First-ever prostate cancer treatment uses gold nanoparticles to destroy tumors

In a recent study, researchers used gold nanoparticles that act as tumor-seeking missiles to remove prostate cancer. The study has begun at The University of...

Skin-like sensor could track oxygenation of healing wounds in real time

A new sensor made of an alternating array of printed light-emitting diodes and photodetectors can detect blood-oxygen levels anywhere in the body. The sensor...
Tiny nanostraws could deliver molecules to cells safely and efficiently

Tiny nanostraws could deliver molecules to cells safely and efficiently

Minuscule nanostraws could help solve the problem of how to deliver precise doses of molecules directly into many cells at once. Researchers can design the...
Game-changing skin sensor could improve life for a million hydrocephalus patients

Game-changing skin sensor could improve life for a million hydrocephalus patients

Most people simply take ibuprofen when they get a headache. But for someone with hydrocephalus - a potentially life-threatening condition in which excess fluid builds...
