Fri, 08/19/2016 - 15:42
A scientific collaboration has discovered previously unknown regularities of arthropod limbs based on studies of the remipede Speleonectes tulumensis, a rare crustacean found in saline waters of caves.

People favour expressive, communicative robots over efficient and effective ones

Fri, 08/19/2016 - 12:46
Making an assistive robot partner expressive and communicative is likely to make it more satisfying to work with and lead to users trusting it more, even if it makes mistakes, a new study suggests.

Scientists combine satellite data, machine learning to map poverty

Thu, 08/18/2016 - 19:00
The availability of accurate and reliable information on the location of impoverished zones is surprisingly lacking for much of the world. Applying machine learning to satellite images could identify impoverished regions in Africa, say researchers.

X-ray optics on a chip

Thu, 08/18/2016 - 15:15
Waveguides are widely used for filtering, confining, guiding, coupling or splitting beams of visible light. However, creating waveguides that could do the same for X-rays has posed tremendous challenges in fabrication, so they are still only in an early stage of development.

Natural scale caterpillar soft robot is powered and controlled with light

Thu, 08/18/2016 - 14:26
Researchers, using the liquid crystal elastomer technology have demonstrated a bioinspired micro-robot capable of mimicking caterpillar gaits in natural scale. The 15-millimeter long soft robot harvests energy from green light and is controlled by spatially modulated laser beam. Apart from traveling on flat surfaces, it can also climb slopes, squeeze through narrow slits and transport loads.

The math of earthquakes

Thu, 08/18/2016 - 13:06
A computational science doctoral student has successfully tied a new mathematical modeling process to the study of earthquakes.

Extension theory of operators in Krein, Pontryagin spaces, applications

Thu, 08/18/2016 - 13:00
A new study investigates and generalizes several well-known results from Extension theory of operators. In a new doctoral dissertation, a researcher has been able to improve a couple of classical theorems known in the area, namely Shmul'yan theorem on completion of nonnegative block operators and Krein famous theorem on description of selfadjoint contractive extensions of a Hermitian contraction.  

Personalized wearable tech can help adults diagnosed with autism manage anxiety

Wed, 08/17/2016 - 18:30
Personalized wearable digital technology can help adults diagnosed with autism understand and manage their anxiety, say researchers.

Interscatter enables first implanted devices, contact lenses, credit cards to 'talk' WiFi

Wed, 08/17/2016 - 18:29
Engineers have introduced a new way of communicating that allows power-constrained devices such as brain implants, contact lenses, credit cards and smaller wearable electronics to talk to everyday devices such as smartphones and watches.

People disregard security warnings on computers because they come at bad times, study finds

Wed, 08/17/2016 - 18:29
Software developers listen up: if you want people to pay attention to your security warnings on their computers or mobile devices, you need to make them pop up at better times. A new study finds the status quo of warning messages appearing haphazardly -- while people are typing, watching a video, uploading files, etc. -- results in up to 90 percent of users disregarding them.

Twitter shows promise in rapid assessment of collective traumas' local impact

Wed, 08/17/2016 - 17:31
An alternative to using Twitter geotags and hashtags to identify community members who have experienced collective trauma, such as a school shooting, shows promise in helping researchers rapidly assess local effects. The approach was deployed to study the impact of deadly gun violence at UC Santa Barbara, Northern Arizona University and Oregon’s Umpqua Community College.

The dangers of Pokémon Go similar to texting

Wed, 08/17/2016 - 17:23
It's taking over headlines around the world -- people being injured playing Pokémon Go, a location-based augmented reality game. A new study says much of the danger in playing the game is similar to the hazards of texting, a subject he has studied in the past.

Babies' spatial reasoning predicts later math skills

Wed, 08/17/2016 - 17:19
Spatial reasoning measured in infancy predicts how children do at math at four years of age, finds a new study. It provides the earliest documented evidence for a relationship between spatial reasoning and math ability.

Reducing gas flares, pollution from oil production

Wed, 08/17/2016 - 17:17
Last year, dozens of major oil companies and oil-producing nations agreed to end the routine flaring of natural gas from wells by 2030. This burning off of uncaptured methane in addition to simply letting it escape into the air -- a process called venting -- releases pollutants and the greenhouse gases carbon dioxide and methane into the atmosphere. Now researchers report a strategy that could help producers work toward this goal.

Many underestimate financial loss due to poor arithmetic

Wed, 08/17/2016 - 17:14
Anyone who has lost out on an investment in recent weeks -- from pension funds and stocks to the housing rental market and currency exchange -- may have lost more than they realize, according to new research.

Combating traffic congestion with advanced data analytics

Wed, 08/17/2016 - 13:12
Researchers are investigating how cell phone data could benefit traffic planning by carrying out a study to determine whether data from cell phone networks could offer a reliable source of information for traffic planning and an improvement over current data collection methods.

Genetically modified soil bacteria work as electrical wires

Tue, 08/16/2016 - 22:26
Scientists have genetically modified a common soil bacteria to create electrical wires that not only conduct electricity, but are thousands of times thinner than a human hair.

Data sharing should become routine for best reponse to public health emergencies

Tue, 08/16/2016 - 19:18
The recent outbreaks caused by Ebola and Zika viruses have highlighted the importance of medical and public health research in accelerating outbreak control and have prompted calls for researchers to share data rapidly and widely during public health emergencies. However, the routine practice of data sharing in scientific research, rather than reactive data sharing, will be needed to effectively prepare for future public health emergencies, according to researchers.
