Using Facebook data as a real-time census

Thu, 10/12/2017 - 16:30
A new study is believed to be the first to demonstrate how present-day migration statistics can be obtained by compiling the same data that advertisers use to target their audience on Facebook, and by combining that source with information from the Census Bureau.

A better understanding of space, via helicopter

Thu, 10/12/2017 - 16:26
An algorithm that helps engineers design better helicopters may help astronomers more precisely envision the formation of planets and galaxies. Researchers have created a new model for understanding how black holes, planets, and galaxies emerge from the vortex-rich environments of space.

Study reveals need for better modeling of weather systems for climate prediction

Thu, 10/12/2017 - 13:15
A team of researchers discovered persistent dry and warm biases in the central U.S. that was caused by poor modeling of atmospheric convective systems. Their findings call for better calculations with global climate models.

Virtual humans work better than current ways to identify post-traumatic stress in soldiers

Thu, 10/12/2017 - 13:10
Researchers find that soldiers are more likely to open up about post-traumatic stress when interviewed by a virtual interviewer, reports a new study. Virtual interviewers can combine the rapport-building skills of human interviewers with feelings safety provided by anonymous surveys to help soldiers to reveal more about their mental health symptoms.

Ultraflat magnets: Atom-thick alloys with unanticipated magnetic properties

Wed, 10/11/2017 - 18:48
Adding rhenium to a two-dimensional alloy induced a structural phase transition in its crystalline order and, surprisingly, a magnetic signature.

Future smartwatches could sense hand movement using ultrasound imaging

Wed, 10/11/2017 - 17:16
New research has shown future wearable devices, such as smartwatches, could use ultrasound imaging to sense hand gestures.

New software speeds origami structure designs

Wed, 10/11/2017 - 16:38
Researchers have developed a new computer-aided approach that streamlines the design process for origami-based structures, making it easier for engineers and scientists to conceptualize new ideas graphically while simultaneously generating the underlying mathematical data needed to build the structure in the real world.

No dark side to using LED lights to supplement WiFi

Wed, 10/11/2017 - 16:06
Energy-saving Light Emitting Diodes (LEDs) could help meet demand for wireless communications without affecting the quality of light or environmental benefits they deliver, new research has shown.

Study shows untapped creativity in workforce

Wed, 10/11/2017 - 16:04
With the U.S. economy less reliant on manufacturing, creativity and innovation are of increasing value. Arts graduates, and others who have developed and honed their creative skills, can be critical assets.

Scientists develop machine-learning method to predict the behavior of molecules

Wed, 10/11/2017 - 13:17
A team of scientists has come up with a machine-learning method that predicts molecular behavior, a breakthrough that can aid in the development of pharmaceuticals and the design of new molecules that can be used to enhance the performance of emerging battery technologies, solar cells, and digital displays.

Scientists develop tool which can predict coastal erosion and recovery in extreme storms

Wed, 10/11/2017 - 13:17
Coastal scientists have developed a computerized model which goes some way to answering their subject's 'holy grail' -- how to use existing data to confidently forecast annual coastal erosion and accretion.

Average wages for all workers, men and women, have increased as a result of women joining the workforce

Wed, 10/11/2017 - 13:17
Economists are continually examining the effect of the economy on women, but this male-dominated field seems to be failing to ask what impact women in turn have on the economy? Researchers have examined how women's participation in the workforce has affected economic growth and productivity in cities across the US. They estimate that every 10% increase in female labor force participation rates increases average real wage growth in cities by approximately 5%.

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.
