Researchers have created a new theoretical framework which could help physicists and device engineers design better optoelectronics, leading to less heat generation and power consumption in electronic devices which source, detect, and control light.
Cybersecurity student researches spent the summer researching how to keep cars safe from cyberattacks during an intensive eight-week cybersecurity summer research program.
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.
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.
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.
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.
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.
A computational science doctoral student has successfully tied a new mathematical modeling process to the study of earthquakes.
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 digital technology can help adults diagnosed with autism understand and manage their anxiety, say researchers.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
