We live in times when among the most limited and precious resources on Earth are air and water. No matter the geographical location, the pollution spreads quickly, negatively affecting even the purest regions like Mount Everest. Thus, anthropogenic activity decreases the quality of the environment, making it harmful for flora and fauna. Current waste treatment methods are not sufficient, so novel and effective methods for maximizing pollutants removal are highly needed.
Superconductivity in two-dimensional (2D) systems has attracted much attention in recent years, both because of its relevance to our understanding of fundamental physics and because of potential technological applications in nanoscale devices such as quantum interferometers, superconducting transistors and superconducting qubits.
How can a highly effective drug be transported to the precise location in the body where it is needed? In the journal Angewandte Chemie, chemists at Heinrich Heine University Düsseldorf (HHU) together with colleagues in Aachen present a solution using a molecular cage that opens through ultrasonification.
Supramolecular chemistry involves the organization of molecules into larger, higher-order structures. When suitable building blocks are chosen, these systems 'self-assemble' from their individual components.
In about a quarter of patients with hereditary diseases, the cause of the disease remains unclear even after extensive genetic testing. One reason is that we still do not know enough about the function of many genes. Of the 30,000 known genes, just a little more than 4,000 have been found to be associated with hereditary diseases.
Knowing what species live in which parts of the world is critical to many fields of study, such as conservation biology and environmental monitoring. This is also how we can identify present or potential invasive and non-native pest species. Furthermore, summarizing what species are known to inhabit a given area is essential for the discovery of new species that have not yet been known to science.
Clothing, from tank tops to parkas, helps people adapt to temperatures outdoors. But you can only put on or take off so much of it, and fluctuations in weather can render what you are wearing entirely inadequate. In a new study in ACS' Nano Letters, researchers describe a high-tech alternative: a reversible textile they designed to trap warmth in the cold and reflect it during hot weather, all while generating small amounts of electricity.
In 2005, greenhouse gas (GHG) emissions from residential energy use hit an all-time high in the United States. Each year since, emissions have dropped at an average annual rate of 2 percent.
Leather is an ever growing multi-billion dollar industry requiring more than 3.8 billion bovine animals - equal to one for every two people on earth - to sustain production each year. And while the products - clothing, shoes, furniture and more - can be quite elegant and durable, the environmental impact of leather production has been severe, leading to deforestation, water and land overuse, environmental pollution, and greenhouse gas emissions.
The ant came in a small vial of ethanol, sealed in a plastic bag, and packed in a small cardboard box. It was addressed to Yale's Douglas B. Booher.
German entomologist Phillip Hoenle had discovered the ant, which he noted had some peculiar features, in a rain forest in Ecuador. Now he wanted Booher, a research associate in the Yale Center for Biodiversity and Global Change and the Department of Ecology & Evolutionary Biology, to confirm whether this trap ant was truly a new species. If so, Hoenle and Booher would have the honor of naming it.
Researchers at CRANN (The Centre for Research on Adaptive Nanostructures and Nanodevices), and the School of Physics at Trinity College Dublin, today announced that a magnetic material developed at the Centre demonstrates the fastest magnetic switching ever recorded.
The team used femtosecond laser systems in the Photonics Research Laboratory at CRANN to switch and then re-switch the magnetic orientation of their material in trillionths of a second, six times faster than the previous record, and a hundred times faster than the clock speed of a personal computer.
Granular materials, such as sand and gravel, are an interesting class of materials. They can display solid, liquid, and gas-like properties, depending on the scenario. But things can get complicated in cases of high-speed vehicle locomotion, which cause these materials to enter a "triple-phase" nature, acting like all three fundamental phases of matter at the same time.
The field of photonics aims to transform all manner of electronic devices by storing and transmitting information in the form of light, rather than electricity. Beyond light's raw speed, the way that information can be layered in its various physical properties makes devices like photonic computers and communication systems tantalizing prospects.
Scientists are certain that dark matter exists. Yet, after more than 50 years of searching, they still have no direct evidence for the mysterious substance.
University of Delaware's Swati Singh is among a small group of researchers across the dark matter community that have begun to wonder if they are looking for the right type of dark matter.
"What if dark matter is much lighter than what traditional particle physics experiments are looking for?" said Singh, an assistant professor of electrical and computer engineering at UD.
ARLINGTON, TX (May 5, 2021) -- Nanoscope Technologies LLC, a biotechnology company developing gene therapies for treatment of retinal diseases, is featuring multiple scientific presentations highlighting its groundbreaking research on optical gene delivery for vision restoration and OCT-guided electrophysiology platforms for characterization of retinal degeneration and assessment of efficacy of cell-gene therapy at the 2021 ARVO annual (vir
The identity of the skeletal remains of a member of the 1845 Franklin expedition has been confirmed using DNA and genealogical analyses by a team of researchers from the University of Waterloo, Lakehead University, and Trent University. This is the first member of the ill-fated expedition to be positively identified through DNA.
DNA extracted from tooth and bone samples recovered in 2013 were confirmed to be the remains of Warrant Officer John Gregory, engineer aboard HMS Erebus. The results matched a DNA sample obtained from a direct descendant of Gregory.
