Smartphone communication streamlines hospital transfers for heart attack patients

Mon, 09/19/2016 - 18:14
Smartphone communication among medical teams at different hospitals can significantly reduce the time it takes for heart attack patients to get lifesaving treatment after a hospital transfer, according to a new study.

Digital photography: The future of small-scale manufacturing?

Mon, 09/19/2016 - 17:23
What if it were possible to quickly and inexpensively manufacture a part simply by using a series of close-range digital images taken of the object? A method called photogrammetry has now been identified for its application in manufacturing. In this technique, digital images of an object that have been taken at various angles are used to create a point cloud -- or a large collection of points used to create 3D representation of existing structures -- from which a computer-aided design (CAD) file can be generated.

Popular reality game Pokémon GO is distracting

Mon, 09/19/2016 - 14:43
Motorists, passengers and pedestrians beware: a new report suggests the wildly popular augmented reality game Pokémon GO is distracting.

What makes a video game great? There’s now a scientific way to stop GUESSing

Mon, 09/19/2016 - 13:45
Human factors researchers have developed the Game User Experience Satisfaction Scale (GUESS), a psychometrically validated instrument that measures satisfaction on key factors such as playability, narratives, creative freedom, social connectivity, and visual aesthetics.

Holographic imaging and deep learning diagnose malaria

Sun, 09/18/2016 - 22:00
A computerized method has been devised to autonomously and quickly diagnose malaria with clinically relevant accuracy -- a crucial step to successfully treating the disease and halting its spread. In 2015 alone, malaria infected 214 million people worldwide, killing an estimated 438,000.

Internet addiction may indicate other mental health problems in college-aged students

Sun, 09/18/2016 - 22:00
A new survey of internet users suggests that people who use the internet excessively may have more mental health problems. Using two scales to evaluate internet use, researchers have found high rates of problematic internet use in a group of primarily college-aged students.  The researchers evaluated internet addiction using the Internet Addiction Test, as well as newer scale of their own design, based on updated addiction criteria. This work may have implications for how psychiatrists approach excessive internet use.

Rise of the internet has reduced voter turnout

Fri, 09/16/2016 - 17:48
During the initial phase of the internet, a “crowding-out” of political information occurred, which has affected voter turnout, new research shows.

Expressing the value of data science in an roi framework

Fri, 09/16/2016 - 17:20
Researchers study how organizations can quantify decision making in data science and present a solution to quantifying the value of data acquisition and modeling in a return on investment (ROI) framework.

Big data gives insight into appeal of services like uber

Fri, 09/16/2016 - 17:20
In a novel test of the benefit a company can generate for consumers, a new study estimates just how much consumers are gaining from the technology company Uber, helping to explain the service's popularity.

Incisionless robotic surgery offers promising outcomes for oropharyngeal cancer patients

Fri, 09/16/2016 - 15:06
An incisionless robotic surgery – done alone or in conjunction with chemotherapy or radiation – may offer oropharyngeal cancer patients good outcomes and survival, without significant pain and disfigurement, research finds.

Meet AISOY1 the Robot, autism therapy assistant

Fri, 09/16/2016 - 13:31
Researchers are collaborating to expand the potential of their robot assistant for the treatment of children diagnosed with autism spectrum disorder (ASD). Specifically, the goal is to explore the ways in which the AISOY robot can enhance therapy sessions at the UMH University Clinic.

When hackers turn out the lights

Fri, 09/16/2016 - 13:30
The development of the smart power grid and the smart meter in our homes to accompany it brings several benefits, such as improved delivery and more efficient billing. Conversely, any digital, connected technology also represents a security risk. Researchers now explain how a malicious third party that hacked into the metering system could manipulate en masse the data being sent back to the smart grid and perhaps trigger a power generation shortfall.

New software helps to find out why 'jumping genes' are activated

Fri, 09/16/2016 - 13:30
The genome is not a fixed code but flexible. It allows changes in the genes. Transposons, however, so-called jumping genes, interpret this flexibility in a much freer way than “normal” genes. They reproduce in the genome and chose their position themselves. Transposons can also jump into a gene and render it inoperative. Thus, they are an important distinguishing mark for the development of different organisms, report scientists.

A tight squeeze for electrons: Quantum effects observed in 'one-dimensional' wires

Thu, 09/15/2016 - 18:34
Researchers have observed quantum effects in electrons by squeezing them into one-dimensional 'quantum wires' and observing the interactions between them. The results could be used to aid in the development of quantum technologies, including quantum computing.

Computer program beats physicians at brain cancer diagnoses

Thu, 09/15/2016 - 17:24
A computer program has been developed that uses radiomic features found in routine MRI scans to distinguish between radiation necrosis and recurrent brain cancer. In a comparison, the program was nearly twice as accurate as a pair of neruoradiologists.

Robo-fish, mimicking nature land professor with U.S. department of the navy research grant

Thu, 09/15/2016 - 16:12
By observing how fish swim and use their fins to move seamlessly within the ocean depths, a researcher is mimicking this movement to increase maneuverability and enhance the motion of underwater vehicles and robotic systems.

Staying the course on a massive open online course

Thu, 09/15/2016 - 16:03
Massive open online courses (MOOCs) are popular with educational establishments as an efficient way to deliver their materials. Unfortunately, student engagement does not match the enthusiasm of the educators and the number who complete any given course is disturbingly low, according to research. The authors of the paper, suggest that an engagement model for MOOCs needs to be implemented and simple steps taken to improve completion rates.

Fighting cancer with space research

Thu, 09/15/2016 - 13:36
For the past 15 years, the big data techniques pioneered by NASA's Jet Propulsion Laboratory in Pasadena, California, have been revolutionizing biomedical research. On Sept. 6, 2016, JPL and the National Cancer Institute (NCI), part of the National Institutes of Health, renewed a research partnership through 2021, extending the development of data science that originated in space exploration and is now supporting new cancer discoveries.

Yes, computing genetic ancestors is super accurate

Thu, 09/15/2016 - 13:00
For decades, geneticists have used programs to compute back through tens of millions of years of mutations to ancestral genes. Are the algorithms really working? A novel lab physical benchmark says yes.
