Fewer than 1% of people globally live in truly remote hinterlands, sharpening the need for better understanding of how urban forms impact food systems as well as social and economic development, according to ground-breaking new research by the Food and Agriculture Organization of the United Nations and the University of Twente.

Rice University engineers hope to make life better for those with replacement joints by modeling how artificial hips are likely to rub them the wrong way.

University at Buffalo researchers are reporting an advancement of a chemical sensing chip that could lead to handheld devices that detect trace chemicals—everything from illicit drugs to pollution—as quickly as a breathalyzer identifies alcohol.

An atypical two-dimensional sandwich has the tasty part on the outside for scientists and engineers developing multifunctional nanodevices.

Many policymakers and educational institutions hope to boost their economies by stimulating students' entrepreneurial intentions. To date, most research concluded that entrepreneurship education could increase these intentions by improving the image that students have of entrepreneurship as a career option, making them see how their environment can help them become entrepreneurs or increasing their self-confidence regarding their entrepreneurial skills. However, recent studies show that even if these goals are achieved... Читать дальше...

Concrete has become our building material of choice for countless structures such as bridges, towers and dams. But it also has a huge environmental footprint mostly due to carbon dioxide emissions from the production of cement—one of its main constituents. Researchers are now experimenting with root vegetables and recycled plastic in concrete to see whether this can make it stronger—and more sustainable—and even power streetlights or air pollution sensors.

Rice University scientists have extended their technique to produce graphene in a flash to tailor the properties of other 2-D materials.

Rhinoceros calf "Jessie" was just four-months-old when she arrived at a shelter in northern South Africa, bleeding from a cut to the shoulder and deeply traumatised.

Armed with picks and shovels, residents of Madrid on Monday slowly shovelled out of Spain's worst snowstorm in decades which turned roads and pavements into skating rinks.

Theoretical and experimental scientists have come together to watch solids vibrate.

Researchers at the LMU, the Bavarian State Collection of Zoology and Hochschule München have discovered a new mechanism for fluorescence in a terrestrial vertebrate

A group of scientists from Russia, China and the United States predicted and then experimentally obtained barium superhydrides, new unusual superconductors. The study was published in Nature Communications.

As LEDs replace traditional lighting systems, they bring more smart capabilities to everyday lighting. While you might use your smartphone to dim LED lighting at home, researchers have taken this further by tapping into dynamically controlled LEDs to create a simple illumination system for 3-D imaging.

A combined team of researchers from the Jet Propulsion Laboratory, California Institute of Technology and the Royal Observatory of Belgium, has found evidence that Mars has a Chandler wobble. In their paper published in the journal Geophysical Research Letters, the group describes their study of decades of data from Mars probes and what it showed them.

Associate Professor of Biology Kourosh Salehi-Ashtiani and NYUAD Senior Research Scientist David Nelson report in a new study that they have successfully cultured and sequenced 107 microalgae species from 11 different phyla indigenous to varied locations and climates to gain insights on genomic differences in saltwater and freshwater microalgae. The researchers have also discovered that these algae genomes show widespread widespread viral-origin gene content.

For years, researchers have worked to repurpose excess atmospheric carbon dioxide into new chemicals, fuels and other products traditionally made from hydrocarbons harvested from fossil fuels. The recent push to mitigate the climactic effects of greenhouse gases in the atmosphere has chemists on their toes to find the most efficient means possible. A new study introduces an electrochemical reaction, enhanced by polymers, to improve CO2-to-ethylene conversion efficiency over previous attempts.

Biotechnologists at Delft University of Technology have built an artificial chromosome in yeast. The chromosome can exist alongside natural yeast chromosomes, and serves as a platform to safely and easily add new functions to the micro-organism. Researchers can use the artificial chromosome to convert yeast cells into living factories capable of producing useful chemicals and even medicines.

A team of researchers from the Centre of the SAVA Region and the University of Antananarivo, both in Madagascar, and one from the University of Goettingen in Germany, has found evidence of a huntsman spider living in a northeastern part of Madagascar creating a trap for tree frogs. In their paper published in the journal Ecology and Evolution, the group describes their observation of a huntsman spider pulling a dead frog into what appeared to be a custom-made leaf trap.

Stimuli-responsive, self-folding, two-dimensional (2-D) layered materials have interesting functions for flexible electronics, wearables, biosensors, and photonics applications. However, limits with scalability and a lack of design tools can prevent high integration and their reliable function. In a new report now published on Advanced Intelligent Systems, Qi Huang, and a team of scientists in chemical and biomolecular engineering and electrical and computer engineering at Johns Hopkins University...

Using the Arecibo 305-m radio telescope, an international team of astronomers has investigated eight binary millisecond pulsars (MSPs). Results of this study, presented in a paper published December 30 on the arXiv pre-print server, provide important information about the properties of these sources.
