Scientists Build World?s Smallest Superconductor
Project Seen As Breakthrough for Producing Nanoscale Electronic Devices
Swapping Graphite Anodes For Silicon Improves Li-ion Battery Capacity Five Times
Battery capacity is the main thing keeping our lifestyles tethered: to the wall socket, to the gas pump, etc. But while we can extend our batteries' charges with smarter, low-power tech, we're...
No new nukes: Obama's nuclear posture points to caution
The U.S. will cut its nuclear weapons stockpile, use such weapons only as a deterrent, and pump more money into the infrastructure to create and sustain such weapons, according to...
Carnegie Mellon student uses skin as input for mobile devices
A combination of simple bio-acoustic sensors and some sophisticated machine learning makes it possible for people to use their fingers or forearms - potentially, any part of their bodies -...
Cold atoms and nanotubes come together in an atomic 'black hole'
Carbon nanotubes, long touted for applications in materials and electronics, may also be the stuff of atomic-scale black holes...
Feature: Lasers could spark clean nuclear power
Researchers hope to one day recreate the nuclear process that drives the Sun, using lasers instead of heat and pressure to fuse atoms together.
Electronic Nose Sniffs Out Asthma
New evidence shows that an "electronic nose" containing an array of gas sensors may have the ability to identify asthma in patients.
Vest Uses Accelerometers and Balloons to Improve Wearer's Balance
People with balance disorders may relearn how to walk correctly with the help of an electronic vest. Relearning how to walk after suffering disease or injury is no easy feat, but researchers...
Researchers holding steady in an atomic-scale tug-of-war
A research team has built an ultra-stable instrument for tugging on chains of atoms, an instrument that can maneuver and hold the position of an atomic probe to within 5...
Solar cells: UQAM researcher solves two 20-year-old problems
Thanks to two technologies developed by Professor Benoit Marsan and his team at the Universite du Quebec a Montreal (UQAM) Chemistry Department, the scientific and commercial future of solar cells...
