What The Study Did: Researchers examined the association of closures of childcare facilities with the employment status of women and men with children in the United States during the COVID-19 pandemic.

What The Study Did: This study evaluated changes in hospitalization and death rates related to COVID-19 before and after U.S. states reopened their economies in 2020.

A near-perfectly preserved ancient human fossil known as the Harbin cranium sits in the Geoscience Museum in Hebei GEO University. The largest of Homo skulls, scientists now say this skull represents a newly discovered human species named Homo longi or "Dragon Man." Their findings, appearing in three papers publishing June 25 in the journal The Innovation, suggest that the Homo longi lineage may be our closest relatives--and may reshape our understanding of human evolution.

James Cook University scientists in Australia believe they have made a breakthrough in the science of keeping premature babies alive.

Chemists at Scripps Research have solved a long-standing problem in their field by developing a method for making a highly useful and previously very challenging type of modification to organic molecules.

Researchers from Tokyo Medical and Dental University (TMDU) have demonstrated direct homophilic interaction of lysosomal-associated membrane protein 2 (LAMP2). They found that the two-domain architecture of LAMP-2 underlies its proper arrangement and function.

University of Tsukuba researchers used time-resolved photoelectron emission microscopy (TR-PEEM) to probe the exciton dynamics of thermally activated delayed fluorescence organic light-emitting diodes (TADF-OLEDs). TADF-OLEDs based on solid-state substrates have significant potential for use in display technology owing to their high efficiency; however, their electron dynamics are not well understood. The TR-PEEM method showed electron accumulation that indicated exciton dissociation. It is hoped that the findings will contribute to advances in OLED displays.

Researchers at Arizona State University are using bioengineering to trigger and control cell differentiation and transition is expand possibilities for diagnostics, vaccine development and therapeutic treatments.

Curtin University research has found tiny amounts of gold can be trapped inside pyrite, commonly known as 'fool's gold,' which would make it much more valuable than its name suggests.

Recently, a Korean research team has drawn attention for developing a technology to reduce the adverse effects by accumulating the peripheral substances of cells on the surfaces of the materials. The Korea Institute of Science and Technology (KIST) has released an announcement that the research team of Dr. Yoon Ki Joung, from the Center for Biomaterials, has successfully developed a material that can be used to accumulate substances present at the cell periphery on the surface of implantable medical materials.

The contemporary materials industry raises the problem of creating a microscopic theory that allows to describe the observed physicochemical properties of a wide class of substances which are in demand in modern industry, medicine, and agriculture.

Perovskite colloidal quantum dots (Pe-CQDs) are highly promising nanocrystals for optoelectronic applications. However, the size of the crystals should ideally be equal to ensure a consistent energy landscape. In a recent study, scientists clarified the relationship between differences in particle size -- polydispersity -- and the optoelectronic characteristics of Pe-CQDs. They showed that using equally sized, or 'monodisperse,' quantum dots results in markedly better performance in Pe-CQD solar cells, paving the way for future optoelectronic devices.

Researchers from University of Tsukuba have found that the share of calls to after-hours house call medical services for fever or cold symptoms decreased during the COVID-19 pandemic in Tokyo, but that the severity of symptoms in those patients was significantly increased. Use of such services could reduce the burden on hospitals and early detection could improve patient outcomes if hesitancy to seek treatment in a pandemic can be addressed.

Researchers have created the first CRISPR-Cas9-based gene drive designed for plants. The new technology, which allows scientists to cut and copy key genetic elements, helps scientists breed plants that defend against crop diseases and withstand the impacts of climate change.

Older men with erectile dysfunction are having more sex than ever before, Pitt study finds.

A new University of Liverpool study could help scientists mitigate the future spread of zoonotic and livestock diseases caused by existing viruses.Researchers have used a form or artificial intelligence (AI) called machine-learning to predict more than 20,000 unknown associations between known viruses and susceptible mammalian species. The findings, which are published in Nature Communications, could be used to help target disease surveillance programmes.

Researchers at the National Institute of Standards and Technology (NIST) and Wavsens LLC have developed a method for using radio signals to create real-time images and videos of hidden and moving objects, which could help firefighters find escape routes or victims inside buildings filled with fire and smoke. The technique could also help track hypersonic objects such as missiles and space debris.

Multisystem Inflammatory Syndrome in Children (MIS-C) significantly affected more Black and Latino children than white children, with Black children at the highest risk, according to a new observational study of 124 pediatric patients treated at Children's National Hospital in Washington, D.C. Researchers also found cardiac complications, including systolic myocardial dysfunction and valvular regurgitation, were more common in MIS-C patients who were critically ill.

Researchers have built and validated an online calculator that empowers individuals 55 and over to better understand the health of their brain and how they can reduce their risk of being diagnosed with dementia in the next five years.

Like two superheroes finally joining forces, Sandia's Z machine -- generator of the world's most powerful electrical pulses -- and Lawrence Livermore's National Ignition Facility -- the planet's most energetic laser source -- have detailed gold and platinum responses to pressures so extreme that their atomic structures momentarily distorted like images in a fun-house mirror.Until now there has been no way to accurately calibrate these pressures , the first step to controlling them.
