Major discovery in controlling quantum states of single atoms

Fri, 02/16/2018 - 19:27
The scientists identified which mechanisms destroy the quantum properties of individual insulator. Using a Scanning Tunneling Microscope, which utilizes an atomically sharp metal tip, they were able to precisely image individual iron atoms and measure and control the time that the iron atom can maintain its quantum behavior.

No testosterone changes found in esports gamers

Fri, 02/16/2018 - 19:26
Players of the competitive esports video game League of Legends showed no change in testosterone during game play, researchers have found.

Teens post online content to appear interesting, popular and attractive

Fri, 02/16/2018 - 16:39
Teens work very hard to create a favorable online image through careful selection of which photos, activities and links to post on Facebook and Instagram, according to a recent study. Content that makes them appear interesting, well-liked and attractive to their friends and peers is a primary goal for adolescents when deciding what to share in digital spaces.

Bringing a hidden superconducting state to light

Fri, 02/16/2018 - 16:05
Using high-intensity pulses of infrared light, scientists found evidence of superconductivity associated with charge 'stripes' in a material above the temperature at which it begins to transmit electricity without resistance -- a finding that could help them design better high-temperature superconductors.

Immune system simulation shows need for multi-target treatments for sepsis

Thu, 02/15/2018 - 19:18
Using a computational model of the human immune system, scientists have shown that efforts to combat sepsis might be more effective if they targeted multiple steps in the molecular processes that drive the illness.

Physicists create new form of light

Thu, 02/15/2018 - 19:17
Physicists have created a new form of light that could enable quantum computing with photons.

OCD treatment could someday start with a brain scan

Thu, 02/15/2018 - 16:05
Researchers have developed a way to use brain scans and machine learning — a form of artificial intelligence — to predict whether people with OCD will benefit from cognitive behavior therapy. The technique could help improve the overall success rate of cognitive behavioral therapy, and it could enable therapists to tailor treatment to each patient.

New printing technique uses cells and molecules to recreate biological structures

Thu, 02/15/2018 - 15:57
Researchers have developed a printing technique using cells and molecules normally found in natural tissues to create constructs that resemble biological structures.

Fingerprints of quantum entanglement

Thu, 02/15/2018 - 15:57
Quantum entanglement is a key feature of a quantum computer. Using conventional methods is hard since they require a large number of repeated measurements. Scientists have developed a novel method where in many cases even a single experimental run suffices to prove the presence of entanglement.

Wed, 02/14/2018 - 20:02
A new type of all-terrain microbot that moves by tumbling could help usher in tiny machines for various applications.

Tissue paper sensors show promise for health care, entertainment, robotics

Wed, 02/14/2018 - 20:02
Engineers have turned tissue paper -- similar to toilet tissue -- into a new kind of wearable sensor that can detect a pulse, a blink of an eye and other human movement. The sensor is light, flexible and inexpensive, with potential applications in health care, entertainment and robotics.

Better together: Silicon qubits plus light add up to new quantum computing capability

Wed, 02/14/2018 - 20:00
In a significant step forward for quantum computing in silicon - the same material used in today's computers -- a team has successfully coupled a single electron's quantum information, or spin, to a particle of light, or photon. The goal is to use light to carry quantum information on a futuristic quantum computing chip.
