Tweeting rage: How immigration policies can polarize public discourse

Mon, 10/16/2017 - 18:48
A study of tweets in the months before and after the 2010 passage of Arizona's "show me your papers" law, findings showed that the average tweet about Mexican immigrants and Hispanics, in general, became more negative. Researchers said the social media data was useful in determining whether people had changed their attitudes about immigrants as a result of the law or whether they had begun behaving differently.

Auto-fix tool gets more programmers to upgrade code, study finds

Mon, 10/16/2017 - 16:21
Failure to make necessary upgrades to software code can have dire consequences, such as the major data breach at Equifax. A recent study finds that auto-fix tools are effective ways to get programmers to make the relevant upgrades -- if programmers opt to use them.

Marketing study examines what types of searches click for car buyers

Mon, 10/16/2017 - 16:21
A new study examines how consumers allocated their time when searching offline and on the internet as they shopped for a new automobile, and what the outcomes were for price satisfaction.

Detailed look at 2-D structure of turbulence in tokamaks

Sat, 10/14/2017 - 15:17
A key hurdle for fusion researchers is understanding turbulence, the ripples and eddies that can cause the superhot plasma that fuels fusion reactions to leak heat and particles and keep fusion from taking place. Comprehending and reducing turbulence will facilitate the development of fusion as a safe, clean and abundant source of energy for generating electricity from power plants around the world.

Spin current detection in quantum materials unlocks potential for alternative electronics

Fri, 10/13/2017 - 16:31
A new method that precisely measures the mysterious behavior and magnetic properties of electrons flowing across the surface of quantum materials could open a path to next-generation electronics. A team of scientists has developed an innovative microscopy technique to detect the spin of electrons in topological insulators, a new kind of quantum material that could be used in applications such as spintronics and quantum computing.

DISTRO: Researchers create digital objects from incomplete 3D data

Fri, 10/13/2017 - 13:17
Depth sensors, such as those of the Microsoft Kinect, are very powerful, but unfortunately they do not work equally well on all materials, which leads to noisy data or even missing measurements.

Tweets can help predict the outcome of soccer matches

Fri, 10/13/2017 - 00:02
Twitter activity can help predict the result of soccer matches when combined with betting market prices, new study shows. The tone of Twitter posts can predict when a team is more likely to win and soccer bets are mispriced, the study found.

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%.
