Anyone who's tried to swat a pesky mosquito knows how quickly the insects can evade a hand or fly swatter. The pests' compound eyes, which provide a wide field of view, are largely responsible for these lightning-fast actions. Now, researchers reporting in ACS Applied Materials & Interfaces have developed compound lenses inspired by the mosquito eye that could someday find applications in autonomous vehicles, robots or medical devices. Watch a video of the lenses here.
COLUMBUS, Ohio -- Schools serving disadvantaged and minority children teach as much to their students as those serving more advantaged kids, according to a new nationwide study.
The results may seem surprising, given that student test scores are normally higher in suburban and wealthier school districts than they are in urban districts serving mostly disadvantaged and minority children.
DURHAM, N.C. -- Electrical engineers at Duke University have harnessed the power of machine learning to design dielectric (non-metal) metamaterials that absorb and emit specific frequencies of terahertz radiation. The design technique changed what could have been more than 2000 years of calculation into 23 hours, clearing the way for the design of new, sustainable types of thermal energy harvesters and lighting.
The study was published online on September 16 in the journal Optics Express.
A unique new flexible and stretchable device, worn against the skin and capable of producing electrical energy by transforming the compounds present in sweat, was recently developed and patented by CNRS researchers from l'Université Grenoble Alpes and the University of San Diego (USA). This cell is already capable of continuously lighting an LED, opening new avenues for the development of wearable electronics powered by autonomous and environmentally friendly biodevices.
CHICAGO (September 25, 2019) - The desire for personalization is permeating all aspects of life, and there is nothing more personal than decisions about health and wellness. As consumers increasingly seek products and services tailored to the individual level, personalized wellness can include everything from genetics-driven diet plans to digital disease management. Business opportunities abound in this ever-growing industry, but it is a high-stakes field: building a robust body of evidence to inform health and wellness products and services is non-negotiable.
Former Hurricane Kiko is now just a remnant low pressure area that has slid into the Central Pacific Ocean. The Global Precipitation Measurement mission or GPM satellite provided a look at the rainfall occurring within the low.
Researchers from HSE University and RANEPA found that in high-income countries, age, rather than the cohort effect, has more impact on religiosity. They predict that this may have an impact on societal structure in the future. The study was published in Journal for the Scientific Study of Religion.
University of Waterloo researchers have developed a novel tool that will enable user-experience designers to create more effective, personalized games and marketing campaigns.
Unlike other tools that categorize gamers by types, the new "player traits model," along with a 25-item survey, can be used to more easily and accurately evaluate the kind of games different people will enjoy. The model is based on five traits: social, aesthetic, challenge, goal, and narrative.
(Philadelphia, PA) - Like catching two fish with one worm, treating two problems with a single drug is efficient, but exceedingly difficult. In particular, for new diabetes medications, in which one drug aims to tackle two major complications of diabetes - the excess of both lipids and glucose in the blood - the therapeutic benefits, while great, frequently are accompanied by dangerous toxic effects to the heart.
India is on a path with dual -- and potentially conflicting -- goals related to the use of citizen data.
To improve the efficiency their municipal services, many Indian cities have started enabling government-service requests, which involves collecting and sharing citizen data with government officials and, potentially, the public. But there's also a national push to protect citizen privacy, potentially restricting data usage. Cities are now beginning to question how much citizen data, if any, they can use to track government operations.
Dropping cloud top temperatures from NASA-NOAA's Suomi NPP satellite indicated Hurricane Lorenzo was getting stronger in the North Atlantic Ocean.
FAYETTEVILLE, Ark. - In a new study, researchers found that unless steps are taken to mitigate climate change, up to 60 percent of current wheat-growing areas worldwide could see simultaneous, severe and prolonged droughts by the end of the century. Wheat is the world's largest rain-fed crop in terms of harvested area and supplies about 20 percent of all calories consumed by humans.
Tropical Storm Karen has crossed over Puerto Rico and into the western Atlantic Ocean. Early on Sept. 25 when Global Precipitation Measurement mission or GPM core satellite passed overhead, the satellite found heavy rain occurring over the territory.
Genetic research led by Queen Mary University of London could open the way to earlier identification of people at risk of heart failure and to the development of new treatments.
A research team in Ehime University prepared a new type of synthetic polymer, which can be degraded into a combination of well-defined low molecular weight compounds under very mild acidic conditions. The new polymer, poly(β-keto enol ether), has great potential to be utilized as an environmentally friendly material in the near future.
