Growing the right crop in the right place within an impaired watershed can achieve significant water quality improvements, according to Penn State researchers, who conducted a novel study in the drainage of a Susquehanna River tributary in an agricultural area in southeastern Pennsylvania.
Bats are the only mammals that can actively fly. Some species travel over one hundred kilometres on their nocturnal excursions in search of food. Researchers at the Max Planck Institute of Animal Behavior in Radolfzell have now discovered that European free-tailed bats use uplifting winds for their ascents - a behaviour that was previously known only from birds. To do this, they tracked the bats using mini GPS loggers and then linked the flight data to weather data. The animals can thus gain altitude of well over 1,000 metres without expending much energy.
According to the Education Act, schools in the ethnically divided Bosnia and Herzegovina must teach students "democratic ideals in a multicultural society." But according to new research from the University of Copenhagen, the opposite happens: Segregated schools perpetuate ethnic divisions between Croats, Serbs and Bosniaks, making reconciliation after the 1992-1995 wars extremely difficult.
The research team of NUST MISIS has presented an improved structure of perovskite solar cells. Scientists have modified perovskite-based solar cells using MXenes -- thin two-dimensional titanium carbides with high electrical conductivity. The MXenes-based modified cells showed superior performance, with power conversion efficiency exceeding 19% (the reference demonstrated 17%) and improved stabilized power output with respect to reference devices. The results have been published in the Nano energy international scientific journal.
The colors in a flower patch appear completely different to a bear, a honeybee, a butterfly and humans. The ability to see these colors is generated by specific properties of opsins - light-sensitive proteins in the retina of our eyes. The number of opsins expressed and the molecular structure of the receptor proteins determines the colors we see.
The COVID-19 pandemic that shuttered cities around the world did not just affect the way we work, study and socialize. It also affected our mobility. With millions of workers no longer commuting, vehicle traffic across Canada has plummeted. This has had a significant impact on the quality of air in major Canadian cities, according to a new study by Concordia researchers.
GAINESVILLE, Fla. --- A ruler and scale can tell archaeologists the size and weight of a fragment of pottery - but identifying its precise color can depend on individual perception. So, when a handheld color-matching gadget came on the market, scientists hoped it offered a consistent way of determining color, free of human bias.
But a new study by archaeologists at the Florida Museum of Natural History found that the tool, known as the X-Rite Capsure, often misread colors readily distinguished by the human eye.
A multi-institutional team became the first to generate accurate results from materials science simulations on a quantum computer that can be verified with neutron scattering experiments and other practical techniques.
Researchers from the Department of Energy's Oak Ridge National Laboratory; the University of Tennessee, Knoxville; Purdue University and D-Wave Systems harnessed the power of quantum annealing, a form of quantum computing, by embedding an existing model into a quantum computer.
Beyond the environmental benefits and lower electric bills, it turns out installing solar panels on your house actually benefits your whole community. Value estimations for grid-tied photovoltaic systems prove solar panels are beneficial for utility companies and consumers alike.
HOUSTON - (Feb. 9, 2021) - Rice University researchers have created a "defective" catalyst that simplifies the generation of hydrogen peroxide from oxygen.
Rice scientists treated metal-free carbon black, the inexpensive, powdered product of petroleum production, with oxygen plasma. The process introduces defects and oxygen-containing groups into the structure of the carbon particles, exposing more surface area for interactions.
Researchers at the University of Campinas’s Chemistry Institute (IQ-UNICAMP) in the state of São Paulo, Brazil, have developed a template-free technique to fabricate cilia of different sizes that mimic biological functions and have multiple applications, from directing fluids in microchannels to loading material into a cell, for example. The highly flexible cilia are based on polymer-coated iron oxide nanoparticles, and their motion can be controlled by a magnet.
A treatment, known as KEDRAB (Rabies Immune Globulin [Human]), currently used in the prevention of rabies has been demonstrated to be safe and effective for patients age 17 and under.
Results published today in Human Vaccines & Immunotherapeutics report the first and only pediatric trial of any human rabies immunoglobulin (HRIG) currently available in the US. Findings have been submitted to the US Food and Drug Administration for review.
Yams are a staple food in West Africa, which produces over 90% of the world's yams each year. Yams play a key role in the food security, economic income, and traditional culture for the region.
While they are commonly assumed to be the same as sweet potatoes in the U.S., yams are a completely different plant. The yam tubers are much starchier and drier compared to sweet potatoes. Yams are native to Africa and Asia, and most Americans have never had a true yam.
Space cooling already accounts for 14% of residential electricity demand in Brazil, and it is expected to increase further because of climate change.
WEST LAFAYETTE, Ind. - Emerging robotics technology may soon help construction companies and contractors create buildings in less time at higher quality and at lower costs.
Purdue University innovators developed and are testing a novel construction robotic system that uses an innovative mechanical design with advances in computer vision sensing technology to work in a construction setting.
The technology was developed with support from the National Science Foundation.
