Kumar, Jin and John L. Reno of Sandia are reporting another terahertz technology breakthrough: they have developed a new phase-locking technique for plasmonic lasers and, through its use, achieved a record-high power output for terahertz lasers.
One of the most intriguing findings about cancer is the association between vitamin D -- a hormone produced by the body in response to ultraviolet (UV)B rays -- and cancer development. While excessive exposure to UVB is said to be the cause of most
All cells in the human body have a shelf-life, but those of the cancerous variety use some cunning trickery to outlive their expiry dates and continue spreading throughout the body.
Scientists have observed the fifth state of matter in space for the first time, offering unprecedented insight that could help solve some of the quantum universe's most intractable conundrums, research showed Thursday.
Suspended animation a step closer? Scientists discover 'snooze button' in the brain that could induce 'hibernation' in humans to help them recover from illness or surgery
1. A memristor has been proposed as an artificial synapse for emerging neuromorphic computing applications. (Nature Nanotechnology) To train a neural network in memristor arrays, changes in weight values in the form of device conductance should be di
The big supertechnology breakthrough that will occur in the ten-15 years will be the emergence of full blown molecular nanotechnology. This will be used to improve computer capacity and speed by over a million times.
A personal, handheld device emitting high-intensity ultraviolet light to disinfect areas by killing the novel coronavirus is now feasible, according to researchers at Penn State, the University of Minnesota and two Japanese universities.
We all like to think of ourselves as heroes. But according to science, the vast majority of people aren't prepared to rebel against totalitarian rulers.
Gilbert and her husband Tim Bartholomaus, a glaciologist at the University of Idaho, first stumbled on a gathering of glacier mice in 2006 when hiking on Root Glacier in Alaska, Candice Wang reports for Popular Science. Then in the summers between 20
Like with MIS-C, children with Kawasaki disease (KD) have symptoms like rash and fever. Kids with KD can also show signs like swollen hands and feet, peeling skin, red eyes, "strawberry tongue," and swollen lymph glands in the neck. KD is a rel
For people who rely on Braille, reading displays and signs in public can be a challenge, but a new system could help make things easier. HaptiRead is a haptic feedback device that uses ultrasound pulses in precise patterns to reproduce Braille text i
After losing four pregnancies, Jennie Agg set out to unravel the science of miscarriage. Then, a few months in, she found out she was pregnant again just as the coronavirus pandemic hit.
How about some good news for a change? Doctors in Italy and the US say that the COVID19 virus may be "declining both in virulence and infection rate." The World Health Organization, however, is unconvinced.
Oak Ridge National Labs is developing 3D printing of a nuclear reactor core using Alloy 617. The previously allowed high temperature materials could not be used above about 750o C (around 1,380o F). The new Alloy 617 can be used in design and constru
Sugar has been implicated in Alzheimer's disease. High levels of blood sugar have been shown to cause memory problems even when they are not at levels that qualify as diabetic and the fluctuation in blood sugar is mild.
Nanox, a startup out of Israel that has developed a small, low-cost scanning system and "medical screening as a service" to replace the costly and large machines and corresponding software typically used for X-rays, CAT scans, PET scans and other
