Engineers have created a new machine learning-assisted method that could make quantum photonic circuit development more efficient by rapidly pre-selecting these solid-state quantum emitters.

Eating less meat and dairy products in favor of plant-based proteins like those found in grains, legumes and nuts could make a huge difference in how much carbon dioxide reaches the atmosphere.
Scientists describe the quirky behavior of one such magnetic topological insulator. The new article includes experimental evidence that intrinsic magnetism in the bulk of manganese bismuth telluride (MnBi2Te4) also extends to the electrons on its electrically conductive surface. Such materials could be just right for making qubits, but this one doesn't obey the rules.
A class of antibiotic molecules called pleicomacrolides inhibit the Nef protein, which HIV uses to evade the body's immune system.
New research reveals in detail how the nucleosomes inside our cells block cGAS from unintentionally triggering the body's innate immune response to our own DNA.
The UNC School of Medicine lab of Camille Ehre, PhD, generated high-powered microscopic images showing startlingly high SARS-CoV-2 viral loads on human respiratory surfaces, ready to spread infection in infected individuals and transmit infection to others.
Anthropogenic ammonia emissions and the water content matter more than dry particle composition for the acidity of atmospheric aerosols in populated regions.
Recent observations have found that something may be missing from the theories of how dark matter behaves. This missing ingredient may explain why researchers have uncovered an unexpected discrepancy between observations of the dark matter concentrations in a sample of massive galaxy clusters and theoretical computer simulations of how dark matter should be distributed in clusters.
Almost seven in 10 Americans would be interested in receiving a COVID-19 vaccine when one becomes available, according to a new study. But researchers say there are concerning gaps in interest, particularly among Black Americans, who suffer disproportionately from the virus.
Systematic efforts and a clear structure are decisive factors in the transition to person-centred health care. A new study reflects what is now a decade of experience and research in the field.
Scientists have made a pivotal discovery that could extend the lifetime of fuel cells that power electric vehicles by eliminating the dissolution of platinum catalysts.
Adults with a higher percentage of fat tissue in their legs were less likely than those with a lower percentage to have high blood pressure. Research findings held true even after adjusting for age, sex, race and ethnicity, education, smoking, alcohol use, cholesterol levels and waist fat, although to a lesser degree.
Previous studies have found the human gut microbiome, bacteria in the gastrointestinal tract, is associated with cardiovascular disease (CVD). This study used machine learning to analyze data from nearly 1,000 stool samples from people with and without CVD. Results show potential for developing a convenient, new diagnostic approach for CVD.
Low blood pressure, or hypotension, in COVID-19 patients with a history of hypertension appears to be a risk factor for kidney damage and death. Reducing hypertension medications if and when COVID-19 patients become hypotensive could prevent acute kidney injury and death, according to a new study. A different study confirmed hypertension is the most common co-existing disease in hospitalized...
The creator of the Australian labradoodle set out to mix poodles and Labrador retrievers to develop a hypoallergic service dog. But, according to a new study, the breed that developed from that cross is primarily poodle.
A comprehensive analysis of antibody responses in coronavirus disease 2019 (COVID-19) patients could inform the development of an effective vaccine, according to a new study.
Newly mated queens of the red fire ant select nest sites with a relatively low pathogen risk by detecting odors produced by soil bacteria that inhibit the growth of ant-infecting fungi, according to a new study.
A new study answers the question of whether or not blood cell telomere length is a suitable proxy for telomere length in other tissues by examining over 20 human tissue types, finding variations and correlations between different tissue types.
The impacts of predator loss and climate change are combining to devastate living reefs that have defined Alaskan kelp forests for centuries, according to new research.
Scientists have compiled a continuous, high-fidelity record of variations in Earth's climate extending 66 million years into the past. The record reveals four distinctive climate states, which the researchers dubbed Hothouse, Warmhouse, Coolhouse, and Icehouse. These major climate states persisted for millions and sometimes tens of millions of years, and within each one the climate shows rhythmic...
Geneticists could identify the causes of disorders that currently go undiagnosed if standard practices for collecting individual genetic information were expanded to capture more variants that researchers can now decipher, concludes new research.
Researchers detected an unexpected 50 percent increase in patients presenting with respiratory illnesses at UCLA Health facilities in the months before the pandemic.
Biological sex has a small but ubiquitous influence on gene expression in almost every type of human tissue, reports a new study. These sex differences are observed for genes involved in many functions, including how people respond to medication, how women control blood sugar levels in pregnancy, how the immune system functions, how cancer develops and male pattern baldness. The information could...
Scientists have completed a wide-ranging set of studies documenting how small changes in DNA sequence can impact gene expression across more than four dozen tissues in the human body. These studies, released in a set of 15 articles, constitute the most comprehensive catalog to date of genetic variations that affect gene expression.
Researchers have discovered a biomarker that can detect autism spectrum disorder (ASD) in preschool-aged children. The new study found that levels of the protein FABP4 were much lower in four- to six-year-old children with ASD than they were in other typically developing children. Experiments in mice that lacked FABP4 revealed changes in neurons that resemble those found in the postmortem brains...
