CHAMPAIGN, Ill. -- Instead of responding to each flight delay as if it were an isolated event, airlines should consider the likelihood of potential disruptions ahead, researchers report in the journal Transportation Science. They developed a new approach that allows airlines to respond to flight delays and cancellations while also incorporating information about likely disruptions later the same day.
Their model suggests this approach could reduce airline recovery costs by 1%-2%, potentially resulting in millions of dollars of savings a year, the researchers say.
A recent study, led by the University of Helsinki, used a novel combination of statistical methods and an exceptional data set collected by hunters to assess the role of protected areas for carnivore conservation in Finland.
Overall, protected areas do not harbour higher densities of large carnivore species than unprotected lands. These areas even had declining wolverine densities within their limits while populations outside remained overall stable over a 30-year study period. The study was published in the journal Nature Communications.
LAWRENCE -- It would be striking for a seasoned entomologist with decades of fieldwork to discover such a large number of species unknown to science. But for University of Kansas student Rachel Smith, an undergraduate majoring in ecology & evolutionary biology, the find is extraordinary: Smith recently published a description of 18 new species of aquatic water beetle from the genus Chasmogenus in the peer-reviewed journal ZooKeys.
Scientists have completed large-scale tests on a new type of five-minute urine test that measures the health of a person's diet, and produces an individual's unique urine 'fingerprint'.
Scientists at Imperial College London in collaboration with colleagues at Northwestern University, University of Illinois, and Murdoch University, analysed levels of 46 different so-called metabolites in the urine of 1,848 people in the U.S.
Scientists from Skoltech and the Chumakov Federal Scientific Center for Research and Development of Immune-and-Biological Products of RAS checked the ability of artificial intelligence that suggest products to buy, recommend new antiviral compounds. The researchers found that advanced algorithms can effectively suggest both music, movies to buy, and compounds with antiviral activity.
The role genetics and gut bacteria play in human health has long been a fruitful source of scientific enquiry, but new research marks a significant step forward in unraveling this complex relationship. Its findings could transform our understanding and treatment of all manner of common diseases, including obesity, irritable bowel syndrome, and Alzheimer's disease.
A new lithium-based electrolyte invented by Stanford University scientists could pave the way for the next generation of battery-powered electric vehicles.
In a study published June 22 in Nature Energy, Stanford researchers demonstrate how their novel electrolyte design boosts the performance of lithium metal batteries, a promising technology for powering electric vehicles, laptops and other devices.
Porous rock containing oil and natural gas are buried so deep inside the earth that shale operators rely on complex models of the underground environment to estimate fossil fuel recovery. These simulations are notoriously complex, requiring highly-skilled operators to run them. These factors indirectly impact the cost of shale oil production and ultimately, how much consumers pay for their fuel.
Laser light traveling through ornately microfabricated glass has been shown to interact with itself to form self-sustaining wave patterns called solitons. The intricate design fabricated in the glass is a type of "photonic topological insulator," a device that could potentially be used to make photonic technologies like lasers and medical imaging more efficient.
Just as a meter stick with hundreds of tick marks can be used to measure distances with great precision, a device known as a laser frequency comb, with its hundreds of evenly spaced, sharply defined frequencies, can be used to measure the colors of light waves with great precision.
HOUSTON -- (June 22, 2020) -- Rice University engineers have created a light-powered catalyst that can break the strong chemical bonds in fluorocarbons, a group of synthetic materials that includes persistent environmental pollutants.
"The lone actor concept appears might do more harm than good in providing an explanation of the causes and origins of terrorist acts," says Associate Professor Bright.
"Significant confusion surrounds correct profiling of lone terrorists. There are key unanswered questions about the extent to which such people actually radicalise and undertake acts of violence alone."
Associate Professor Bright warns that the inaccurate profiling of a lone terrorist may deflect attention away from links they have with other individuals including established terrorist groups.
Electronic properties of condensed matter are often determined by an intricate competition between kinetic energy that aims to overlap and delocalize electronic wave functions across the crystal lattice, and localizing electron-electron interactions. In contrast, the gaseous phase is characterized by valence electrons tightly localized around the ionic atom cores in discrete quantum states with well-defined energies.
A team of Korean researchers has developed a processing technology for maximizing energy densities of high-capacity batteries. The joint research team, which consists of Dr. Lee, Minah of the Center for Energy Storage Research and Dr.
Traveling restraints and shelter-in-place orders that grounded planes and emptied streets during the first wave of the COVID-19 pandemic brought greenhouse gas emissions down and air quality up. In a commentary published June 19 in the journal Joule, environmental economists argue COVID-19 may seem like a "silver lining" for climate change in the short run, but in the long run it is more likely to harm the climate due to its potential to delay clean energy investments and innovation.
