An AI for deciphering what animals do all day

Mon, 04/30/2018 - 17:17
Researchers show how an algorithm for filtering spam can learn to pick out, from hours of video footage, the full behavioral repertoire of tiny, pond-dwelling Hydra. By comparing Hydra's behaviors to the firing of its neurons, the researchers hope to eventually understand how its nervous system, and that of more complex animals, works.

The digital transformation of news media and the rise of online disinformation

A new report contains an overview of the relevant economic research literature on the digital transformation of news markets and related impact on the quality of news.

Be wary of cosmetic surgeons' online reviews

Thu, 04/26/2018 - 22:00
Consumers consider online reviews important for choosing physicians, but they should be wary of using those ratings to choose plastic surgeons. The reviews tend to be polarized, and some are written by people whom consulted with the doctor but never had surgery, reports a new study.

Improving mid-infrared imaging and sensing

Thu, 04/26/2018 - 22:00
A new way of taking images in the mid-infrared part of the spectrum, developed by researchers could enable a wide variety of applications, including thermal imaging, biomedical sensing, and free-space communications.

New computational model enables personalized simulation of exercise's metabolic effects

Thu, 04/26/2018 - 18:15
A new mathematical model incorporates personalized details to simulate the metabolic effects of exercise. The model can be adapted to different individual characteristics, such as age and weight, as well as different types and intensities of exercise.

Why a robot can't yet outjump a flea

Thu, 04/26/2018 - 18:15
Smashing mantis shrimp. Snapping trap-jaw ants. Stinging jellyfish. Some of the fastest living things -- at least over short distances -- are also the smallest. A new mathematical model explores how the smallest and speediest things on Earth generate their powerful jumps, snaps, strikes and punches. The model could help explain why robots can't hold a candle to the fastest-moving insects and other tiny-but-powerful creatures, and how they could get closer.

Energy conversion: Speeding up material discovery

Thu, 04/26/2018 - 16:59
Researchers have developed an algorithm that can discover and optimize thermoelectic materials for energy conversion in a matter of months, relying on solving quantum mechanical equations, without any experimental input.

A simple method etches patterns at the atomic scale

Thu, 04/26/2018 - 16:59
A precise, chemical-free method for etching nanoscale features on silicon wafers has now been developed.

Transparent eel-like soft robot can swim silently underwater

Thu, 04/26/2018 - 14:29
An innovative, eel-like robot developed by engineers and marine biologists can swim silently in salt water without an electric motor. Instead, the robot uses artificial muscles filled with water to propel itself. The foot-long robot, which is connected to an electronics board that remains on the surface, is also virtually transparent.

Discovery of new material is key step toward more powerful computing

Thu, 04/26/2018 - 12:55
Researchers have created a new material that represents a key step toward the next generation of supercomputers.

Weather associated with sentiments expressed on social media

Sentiments expressed on Facebook and Twitter may be associated with certain weather patterns.

Emerging memory devices used to develop electronic circuits for cybersecurity applications

Wed, 04/25/2018 - 20:20
While we embrace the way the Internet of Things already is making our lives more streamlined and convenient, the cybersecurity risk posed by millions of wirelessly connected gadgets, devices and appliances remains a huge concern. Even single, targeted attacks can result in major damage; when cybercriminals control and manipulate several nodes in a network, the potential for destruction increases.

Switch controls light on a nanoscale for faster information processing

Wed, 04/25/2018 - 17:18
Researchers have helped design a compact switch that enables light to be more reliably confined to small computer chip components for faster information processing.

Agent 007: Organic Molecules as bearers of secrets

Wed, 04/25/2018 - 16:02
In the digital age, security of sensitive information is of utmost importance. Many data are encrypted these methods use a password for decryption, and in most cases, exactly this password is the entrance gate for hackers. Scientists use a new and highly secure approach by combining computer science with chemistry and a conventional encryption method with a chemical password.

Move over Tupac! Life-size holograms set to revolutionize videoconferencing

Wed, 04/25/2018 - 16:02
TeleHuman 2 -- the world's first truly holographic videoconferencing system -- is being unveiled. TeleHuman2 allows people in different locations to appear before one another in life-size 3-D -- as if they were in the same room.

Wed, 04/25/2018 - 16:02
Computer scientists have created a deep-learning, software-coding application that can help human programmers by writing chunks of code in response to keywords.

Easier way to predict how chemical compounds will interact

Wed, 04/25/2018 - 16:01
New research has revealed that simple, commercially available computer programmes could be used to design next generation drug-delivery systems by predicting more easily how different chemical compounds interact.

Bento browser makes it easier to search on mobile devices

Wed, 04/25/2018 - 13:37
Searches involving multiple websites can quickly get confusing, particularly when performed on a mobile device with a small screen. A new web browser now brings order to complex searches in a way not possible with conventional tabbed browsing. The Bento browser stores each search session as a project workspace that keeps track of the most interesting or relevant parts of visited web pages.
