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.

All-terrain microbot moves by tumbling over complex topography

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.

Neural networks everywhere

Wed, 02/14/2018 - 19:58
Special-purpose chip that performs some simple, analog computations in memory reduces the energy consumption of binary-weight neural networks by up to 95 percent while speeding them up as much as sevenfold.

Video games to improve mobility after a stroke

Wed, 02/14/2018 - 14:39
New research reveals that, after a cerebral infarction, injuries in areas that control attention also cause motility problems. The authors propose to complement physiotherapy with another type of cognitive training, such as video games.

Can a cockroach teach a robot how to scurry across rugged terrain?

Tue, 02/13/2018 - 18:29
Researchers build a robot that moves more like a cockroach.

Missing link to novel superconductivity revealed

Tue, 02/13/2018 - 18:29
Scientists have discovered a state of magnetism that may be the missing link to understanding the relationship between magnetism and unconventional superconductivity.

Graphene on toast, anyone?

Tue, 02/13/2018 - 17:32
The same scientists who introduced laser-induced graphene have enhanced their technique to produce what may become a new class of edible electronics.

Energy-efficient encryption for the internet of things

Tue, 02/13/2018 - 17:04
A special-purpose chip hardwired to implement elliptic-curve cryptography in general and the datagram transport layer security protocol in particular reduces power consumption by 99.75 percent and increases speed 500-fold, to help enable the internet of things.

New machine learning algorithm uncovers time-delayed interactions in cells

Mon, 02/12/2018 - 21:09
A new algorithm uses time-series data to show the cause-and-effect interactions that take place inside of living cells.

New method for waking up devices

Mon, 02/12/2018 - 20:07
A device that's turned off doesn't suck battery life, but it also doesn't work. Now a low-power system that's always on the alert can turn devices on when they are needed, saving energy in the networked internet of things.

Study finds gender and skin-type bias in commercial artificial-intelligence systems

Mon, 02/12/2018 - 17:12
A new article shows that three commercial facial-analysis programs demonstrate gender and skin-type biases, and suggests a new, more accurate method for evaluating the performance of such machine-learning systems.
