Raging Bull: First study to find link between testosterone and stock market instability

Tue, 10/10/2017 - 19:27
In the U.S. today, the majority of professional stock market traders are young males and new evidence suggests biology strongly influences their trading behavior. According to a new study this could be a significant contributor to fluctuations in the market, as high testosterone levels can cause these traders to overestimate future stock values and change their trading behavior, leading to dangerous prices bubbles and subsequent crashes.

Changes in perspective may affect how useful drones really are

Tue, 10/10/2017 - 17:39
Users have trouble utilizing images from unmanned aerial systems (UASs), or drones, to find the position of objects on the ground, research shows. This finding highlights challenges facing the use of UAS technology for emergency operations and other applications, while offering guidance for future technology and training development.

Machine learning translates 'hidden' information to reveal chemistry in action

Tue, 10/10/2017 - 16:41
Scientists have developed a new way to capture the details of chemistry choreography as it happens. The method -- which relies on computers that have learned to recognize hidden signs of the steps -- should help them improve the performance of catalysts to drive reactions toward desired products faster.

Forget about it: A material that mimics the brain

Tue, 10/10/2017 - 16:40
Inspired by human forgetfulness -- how our brains discard unnecessary data to make room for new information -- scientists conducted a recent study that combined supercomputer simulation and X-ray characterization of a material that gradually 'forgets.' This could one day be used for advanced bio-inspired computing.

A self-propelled catheter with earthworm-like peristaltic motion

Tue, 10/10/2017 - 15:46
A research team has developed a mechanism of a self-propelled catheter capable of generating peristaltic motion just like an earthworm by applying pneumatic pressure inside only one tube. The goal is to develop an AutoGuide robot that propels itself inside bronchi, automatically reaching the target lesion within the lungs, and can take a lesion sample and provide treatment.

Electrons surfing on a laser beam

Tue, 10/10/2017 - 15:46
The largest particle accelerator in the world - the Large Hadron Collider at CERN in Switzerland -- has a circumference of around 26 kilometers. Researchers are now attempting to go to the other extreme by building the world's smallest machine of this kind -- a particle accelerator that fits on a microchip.

This soft robotic gripper can screw in your light bulbs for you

Tue, 10/10/2017 - 15:46
How many robots does it take to screw in a light bulb? The answer: just one, assuming you're talking about a newly created robotic gripper. The engineering team has designed and built a gripper that can pick up and manipulate objects without needing to see them and needing to be trained.

Seeing the next dimension of computer chips

Tue, 10/10/2017 - 15:46
Researchers used a scanning tunneling microscope to image the side-surfaces of 3-D silicon crystals for the first time. The pictures, captured with atomic-level of resolution, can help semiconductor manufacturers build the next generation of computer chips with three-dimensional features.

Computer program detects differences between human cells

Tue, 10/10/2017 - 14:57
'How many different cell types are there in a human body? And how do these differences develop? Nobody really knows.' But thanks to a new method, that may be about to change.

Novel circuit design boosts wearable thermoelectric generators

Mon, 10/09/2017 - 13:33
Using flexible conducting polymers and novel circuitry patterns printed on paper, researchers have demonstrated proof-of-concept wearable thermoelectric generators that can harvest energy from body heat to power simple biosensors for measuring heart rate, respiration or other factors.

Digital services collect unnecessary personal information

Mon, 10/09/2017 - 13:29
Digital services that require users to log in with a personal account often collect more information about users than is needed. Certain policies may encroach on our privacy.

Connecting the Dots

Fri, 10/06/2017 - 17:22
Nuclear physicists are using America’s most powerful supercomputers to characterize behavior of objects, from subatomic neutrons to neutron stars, that differ dramatically in size yet are closely connected by physics.

Energy against the current on a quantum scale, without contradicting the laws of physics

Fri, 10/06/2017 - 15:23
In a classical thermodynamic system, the heat current flows from the hotter body to the colder one, or electricity from the higher voltage to the lower one. The same thing happens in quantum systems, but this state can be changed, and the flow of energy and particles can be reversed if a quantum observer is inserted into the system.

Sensitivity to time improves performance at remotely controlling devices

Fri, 10/06/2017 - 15:23
A new study finds that people who are more sensitive to the passage of time are better at accounting for the latency -- or time lag -- inherent in remotely controlling robots or other tools.

Predicting insect feeding preferences after deforestation

Fri, 10/06/2017 - 14:18
Understanding how parasitoids and hosts interact, and how their interactions change with human influence, is critically important to understanding ecosystems. New research finds mathematical models can predict complex insect behavioral changes using a simple description of insect preferences.

Exotic quantum particle observed in bilayer graphene

Fri, 10/06/2017 - 13:22
Physicists have definitively observed an intensely studied anomaly in condensed matter physics -- the even-denominator fractional quantum Hall state -- via transport measurement in bilayer graphene.

Engineers invent breakthrough millimeter-wave circulator IC

Fri, 10/06/2017 - 12:59
Researchers continue to break new ground in developing magnet-free non-reciprocal components in modern semiconductor processes. They have built the first magnet-free non-reciprocal circulator on a silicon chip that operates at millimeter-wave frequencies, enabling circulators to be built in conventional semiconductor chips and operate at millimeter-wave frequencies, enabling full-duplex or two-way wireless.

New technology uses mouth gestures to interact in virtual reality

Thu, 10/05/2017 - 18:42
Researchers have developed a new technology that allows users to interact in a virtual reality environment using only mouth gestures.

Simulating a brain-cooling treatment that could one day ease epilepsy

Thu, 10/05/2017 - 18:18
Using computer simulation techniques, scientists have gained new insights into the mechanism by which lowering the temperature of specific brain regions could potentially treat epileptic seizures.
