Trapped Rydberg ions can be the next step towards scaling up quantum computers to sizes where they can be practically usable, a new study in Nature shows.
Different physical systems can be used to make a quantum computer. Trapped ions that form a crystal have led the research field for years, but when the system is scaled up to large ion crystals this method gets very slow. Complex arithmetic operations cannot be performed fast enough before the stored quantum information decays.
Making an accurate prediction based on observed data, in particular from short-term time series, is of much concern in various disciplines, arising from molecular biology, neuroscience, geoscience, economics to atmospheric sciences due to either data availability or time-variant non-stationarity. However, most of the existing methods require sufficiently long measurements of time series or a large number of samples, and there is no effective method available for the prediction only with short-term time-series because of lack of information.
PHILADELPHIA - Even small amounts of breastmilk strongly influences the accumulation of viral populations in the infant gut and provides a protective effect against potentially pathogenic viruses, according to researchers who examined hundreds of babies in a study from the Perelman School of Medicine at the University of Pennsylvania.
Energy conservation lies at the core of every physical theory. Effective mathematical models however can feature energy gain and/or loss and thus break the energy conservation law by only capturing the physics of a subsystem. As a result, the Hamiltonian, the function that describes the system's energy, loses an important mathematical property: it is no longer Hermitian. Such non-Hermitian Hamiltonians have successfully described experimental setups for both classical problems - in e.g.
Patients with Alzheimer's disease (AD) are often prescribed drugs for other conditions -- including diabetes or high blood pressure -- at the same doses as those without dementia. That practice might need to be reexamined in the wake of new mouse studies reported in ACS' Molecular Pharmaceutics. The findings suggest that AD could alter absorption of medications from the digestive tract, so dosages might need to be adjusted for these patients.
(Boston)--Women Veterans with more symptoms of post-traumatic stress disorder
(PTSD) or moral injury (guilt, shame or demoralization in response to participating in or witnessing events that violate one's sense of right and wrong), are at greater risk for negative pregnancy outcomes and postpartum depression in the three years following discharge from military service.
The number of women in the military and associated veteran population continues to
grow with the largest increases observed among women of child-bearing age.
Gluten is enemy No. 1 for those with celiac disease, and it's hard to avoid. Episodes of this chronic autoimmune illness can be triggered by ingesting gluten, a key protein in wheat and some other grains. Researchers have been exploring how gut bacteria, especially Bifidobacteria, could be used as a treatment. Now, scientists publishing the results of laboratory experiments in ACS' Journal of Agricultural and Food Chemistry report how specific types of Bifidobacteria work.
In "Aging and Public Health," a new special issue of the journal Innovation in Aging from The Gerontological Society of America, researchers look at public health interventions that work to foster healthy aging.
The issue's eight papers focus on how best to lengthen the period of good health, a sustained sense of well-being, and extended periods of social engagement and productivity as our society ages, while emphasizing elements in the realm of public health.
Cutting down forests means we're also cutting down woodland caribou, says a pioneering study by University of Guelph ecologists showing that logging in Ontario's extensive boreal stands threatens populations of the elusive but iconic herbivore.
Regular exercise may reduce the risk of acute respiratory distress syndrome, a major cause of death in patients with the COVID-19 virus, a top exercise researcher reports. He is urging people to exercise based on his findings, which also suggest a potential treatment approach.
When adult brain cells are injured, they revert to an embryonic state, according to new findings published in the April 15, 2020 issue of Nature by researchers at University of California San Diego School of Medicine, with colleagues elsewhere. The scientists report that in their newly adopted immature state, the cells become capable of re-growing new connections that, under the right conditions, can help to restore lost function.
LAWRENCE -- You might own something made from mahogany like furniture, paneling or a musical instrument.
Mahogany is a commercially important wood, valued for its hardness and beauty. The United States is the world's top importer of the tropical timber from leading producers like Peru and Brazil. Unfortunately, mahogany is harvested illegally a lot of the time.
People handle monarch butterflies. A lot. Every year thousands of monarch butterflies are caught, tagged and released during their fall migration by citizen scientists helping to track their movements. And thousands of caterpillars are reared by hand or used in classroom demonstrations and outreach events.
These activities can provide valuable scientific data and educational benefits for the people participating in them. But how do the monarchs themselves feel about being handled by humans?
DALLAS - April 15, 2020 - Researchers at UT Southwestern Medical Center have uncovered the detailed shape of a key protein involved in muscle contraction. The report, published today in Neuron, may lead to improved understanding of muscle-weakening genetic conditions called congenital myasthenic syndromes (CMS).
Two months after creating a structural 3D roadmap of the novel coronavirus and sharing it with the scientific community worldwide, Worcester Polytechnic Institute (WPI) bioinformatics researcher Dmitry Korkin has published a paper on the topic in Viruses, a leading virology journal.
