Growing resistance to our go-to antibiotics is one of the biggest threats the world faces. As common bacteria like strep and salmonella become resistant to medications, what used to be easily treatable infections can now pose difficult medical challenges.
New research from the University of Georgia shows that there may be more antimicrobial-resistant salmonella in our food animals than scientists previously thought.
Researchers from Baidu Research Robotics and Auto-Driving Lab (RAL) and the University of Maryland, College Park, have introduced an autonomous excavator system (AES) that can perform material loading tasks for a long duration without any human intervention while offering performance closely equivalent to that of an experienced human operator.
AES is among the world's first uncrewed excavation systems to have been deployed in real-world scenarios and continuously operating for over 24 hours, bringing about industry-leading benefits in terms of enhanced safety and productivity.
In cases of breast cancer, bone metastasis - when cancer cells spread to new sites in the bone - causes the most breast cancer-related harm and is often incurable in advanced disease. A new study by University of Arizona Health Sciences researchers found that cancer cells become more aggressive when exposed to tissue stiffening and that these changes persist over time.
In hospitals, we know that the nurses are the first to deal with patients in pain. For any ailment, including patients needing hemodialysis, the knowledge of pain management, the nurses have, allow them to provide optimal pain management.
Ten estuaries on the West Coast of North America have been identified as priority locations for expanding the use of conservation aquaculture in a study led by the Native Olympia Oyster Collaborative and funded by the Science for Nature and People Partnership (SNAPP). SNAPP is a research collaboration supported by the National Center for Ecological Analysis & Synthesis (NCEAS) at UC Santa Barbara.
Electron motion in atoms and molecules is of fundamental importance to many physical, biological, and chemical processes. Exploring electron dynamics within atoms and molecules is essential for understanding and manipulating these phenomena. Pump-probe spectroscopy is the conventional technique. The 1999 Nobel Prize in Chemistry provides a well-known example wherein femtosecond pumped laser pulses served to probe the atomic motion involved in chemical reactions.
New Brunswick, N.J. (June 28, 2021) - Rutgers researchers have developed a machine learning model using a physics-based simulator and real-world meteorological data to better predict offshore wind power.
The findings appear in the journal Applied Energy.
For decades, researchers have been working toward mitigating excess atmospheric carbon dioxide (CO2) emissions. One promising approach captures atmospheric CO2 and then, through CO2 electrolysis, converts it into value-added chemicals and intermediates--like ethanol, ethylene, and other useful chemicals. While significant research has been devoted to improving the rate and selectivity of CO2 electrolysis, reducing the energy consumption of this high-power process has been underexplored.
[BRIDGEWATER, NJ; June 29, 2021] The American Association of Feline Practitioners (AAFP) has released the updated 2021 AAFP Feline Senior Care Guidelines to be published in the July issue of the Journal of Feline Medicine and Surgery. This update provides emerging advances in feline medicine with respect to the aging cat. The Task Force of experts provides a thorough current review in feline medicine that emphasizes the individual senior patient.
Atomic nuclei contain enormous energy that can be extracted through their fission mechanism, for example, as a result of the radioactive decay of uranium or plutonium nuclei. Likewise, a quantum of light of several electron-volts (2.4 eV in a laser pointer with a green beam) has colossal energy. If all photons were absorbed by matter, then its temperature could reach several thousand degrees. However, in practice this does not happen.
As our society and transportation systems become increasingly electrified, scientists worldwide are seeking more efficient and higher capacity storage systems. Researchers at KAUST have made an important contribution by modifying lithium-sulfur (Li-S) batteries to suppress a problem known as polysulfide shuttling.
"The bottleneck in the utilization of renewable energy, especially in transportation, is the need for high-density batteries," says Eman Alhajji, Ph.D. student and first author of the research paper.
What if electricity could be squeezed out of something? It turns out some materials have this property. Piezoelectricity is the electric charge that accumulates in certain solids when mechanical stress is applied on them. Piezoelectric materials, like bismuth ferrite thin films, when grown on a single lanthanum aluminate substrate give rise to highly strained epitaxial thin films that exhibit excellent electromechanical and ferroelectric properties.
A FLEET theoretical study out this week has found a 'smoking gun' in the long search for the topological magnetic monopole referred to as the Berry curvature.
This discovery is a breakthrough in the search for topological effects in non-equilibrium systems .
The group, led by Dimi Culcer at UNSW, identified an unconventional Hall effect driven by an in-plane magnetic field in semiconductor hole systems, which is traced exclusively to the Berry curvature.
HARWELL, UK (29 June 2021) Researchers working on the Faraday Institution project on the recycling of lithium-ion batteries (ReLiB) at the Universities of Leicester and Birmingham have solved a critical challenge in the recovery of materials used in electric vehicle batteries at the end of their life, enabling their re-use in the manufacture of new batteries. The new method, which uses ultrasonic waves to separate out valuable material from the electrodes, is 100 times quicker, greener and leads to a higher purity of recovered materials relative to current separation methods.
