ITHACA, N.Y. - Electrons are very much at the mercy of magnetic fields, which scientists can manipulate to control the electrons and their angular momentum - i.e. their "spin."
A Cornell team led by Greg Fuchs, assistant professor of applied and engineering physics in the College of Engineering, in 2013 invented a new way to exert this control by using acoustic waves generated by mechanical resonators. That approach enabled the team to control electron spin transitions (also known as spin resonance) that otherwise wouldn't be possible through conventional magnetic behavior.
This it is the story of a unique material - made of a single compound, it conducts electrons in different ways on its different surfaces and doesn't conduct at all in its middle. It is also the story of three research groups - two at the Weizmann Institute of Science and one in Germany, and the unique bond that has formed between them.
A forest's ability to store carbon depends significantly on the bedrock beneath, according to Penn State researchers who studied forest productivity, composition and associated physical characteristics of rocks in the Appalachian ridge and Valley Region of Pennsylvania.
The results have implications for forest management, researchers suggest, because forests growing on shale bedrock store 25% more live, aboveground carbon and grow faster, taking up about 55% more carbon each year than forests growing on sandstone bedrock.
Health and safety risks from product consumption, including obesity, vaping, drug misuse and texting while driving, as well as circumstances surrounding the coronavirus pandemic, pose significant problems in the United States and around the world.
Researchers at the University of Colorado Boulder's Soft Materials Research Center (SMRC) have discovered an elusive phase of matter, first proposed more than 100 years ago and sought after ever since.
The team describes the discovery of what scientists call a "ferroelectric nematic" phase of liquid crystal in a study published today in the Proceedings of the National Academy of Sciences. The discovery opens a door to a new universe of materials, said co-author Matt Glaser, a professor in the Department of Physics.
Speaking requires both sides of the brain. Each hemisphere takes over a part of the complex task of forming sounds, modulating the voice and monitoring what has been said. However, the distribution of tasks is different than has been thought up to now, as an interdisciplinary team of neuroscientists and phoneticians at Goethe University Frankfurt and the Leibniz-Centre General Linguistics Berlin has discovered: it is not just the right hemisphere that analyses how we speak - the left hemisphere also plays a role.
The parasites responsible for malaria seem to march to their own beat.
The mystery behind the molecular basis of how these parasites synch their rhythm in replication to the host's clock-driven rhythms has been solved. A new genetic analysis led by KAUST scientists revealed Plasmodium parasites have internal timekeeping systems that help the organism maintain essential oscillations in gene expression levels and cell cycle activities.
A new research paper co-authored by a Virginia Tech assistant professor of physics provides a new explanation for two recent strange events that occurred in Antarctica - high-energy neutrinos appearing to come up out of the Earth on their own accord and head skyward.
As the first wave of the COVID-19 pandemic wanes in Europe, many countries are relaxing their lockdown rules, but the advice for non-essential workers is to continue working from home if possible. The important question when lockdown should be lifted for non-essential workers in the UK and elsewhere is answered in a new study in Frontiers in Public Health.
WASHINGTON, June 9, 2020 -- Benchtop tools for studying the respiratory system misrepresent the interdependence between the diaphragm, abdomen and lungs. Meanwhile, computational models often hide the mechanisms in a black box computation, without a clear picture of what transpires in the process.
This means students form a poor understanding of respiratory mechanisms and makes it hard to train clinicians for real scenarios or prototype embeddable medical devices.
DALLAS - June 9, 2020 - Serotonin, a chemical known for its role in producing feelings of well-being and happiness in the brain, can reduce the ability of some intestinal pathogens to cause deadly infections, new research by UT Southwestern scientists suggests. The findings, publishing online today in Cell Host & Microbe, could offer a new way to fight infections for which few truly effective treatments currently exist.
A study led by the Institut de Neurociències (INc-UAB) describes a new strategy to tackle cancer, based on inducing a potent stress in tumor causing cell destruction by autophagy. The mechanism has been revealed using the new antitumor drug ABTL0812, currently in clinical trial. Results has been validated using samples from oncologic patients and published in Autophagy.
When a lake is covered with green scums during a warm summer, cyanobacteria - often called blue-green algae - are usually involved. Mass development of such cyanobacteria is bad for water quality because they can deprive the water of oxygen and produce toxins. But cyanobacteria can become sick, when for instance infected by fungal parasites. Researchers from the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) found out that these infections do not only kill cyanobacteria, they also make them easier to consume for their natural predators.
Scientists have described a potential new therapeutic strategy for slowing down early-stage Huntington's disease in a new study published today in eLife.
The research in mice indicates that targeting the histamine H3 receptor (H3R) - a well-established drug target for other conditions such as hay fever - could help to prevent imbalances in dopamine signalling that lead to brain-cell death and deficits in movement and memory.
A key set of proteins that help regulate hormones necessary for many essential functions in humans and other vertebrates have ancient origins in much simpler creatures such as sea cucumbers, says a new study published today in eLife.
