A new national study published in Public Health Nutrition on July 15 found that Americans experiencing food insufficiency were three times as likely to lack mental health support during the COVID-19 pandemic than those not experiencing food insufficiency.

Scientists on the hunt for an unconventional kind of superconductor have produced the most compelling evidence to date that they've found one. In a pair of papers published in Science and Nature Communications, researchers at the University of Maryland's Quantum Materials Center and colleagues have shown that uranium ditelluride displays many of the hallmarks of a topological superconductor--a material that may unlock new ways to build quantum computers and other futuristic devices.

A new study shows that it is possible to use mechanical force to deliberately alter chemical reactions and increase chemical selectivity - a grand challenge of the field.

A collaborative team from the Terasaki Institute for Biomedical Innovation has designed a wearable strain sensing device that can effectively detect a wide range of strains.

A new tool developed by a University of Minnesota research team allows farmers to create a budget balance sheet of any nitrogen reduction plans and see the economic and environmental cost, return and margins, all customized to fields under their management.

The American Academy of Sleep Medicine (AASM) and Sleep Research Society (SRS) have published evidence-based guiding principles to help employers determine optimal work shift durations for their workplace. With a process that assesses risks, considers countermeasures, and institutes an informed approach to determine and evaluate shift durations, employers can make shift duration decisions that manage fatigue-related risks while also maintaining high productivity and safety.

Researchers from Skoltech have found a way to help computer vision algorithms process satellite images of the Earth more accurately, even with minimal data for training. This will make various remote sensing tasks easier for machines and, ultimately, the people who use their data.

Burnout. It is a syndrome that is said to afflict humans who feel chronic stress. But after conducting a novel study using trail cameras showing the interactions between white-tailed deer fawns and predators, a Penn State researcher suggests that prey animals feel it, too.

Earth's climate was relatively stable for a long period of time. For three billion years, temperatures were mostly warm and carbon dioxide levels high - until a shift occurred about 400 million years ago. A new study suggests that the change at this time was accompanied by a fundamental alteration to the carbon-silicon cycle.

Corn growers can choose from a wide array of products to make the most of their crop, but the latest could bring seaweed extract to a field near you. The marine product is just one class in a growing market of crop biostimulants marketed for corn. Biostimulants benefit crops and soil, but the dizzying array of products has farmers confused, according to Fred Below, corn and soybean researcher at the University of Illinois.

A new study identified groups that are more likely to be placed in extended solitary management (ESM). The study found that individuals sent to ESM differed considerably from the rest of the prison population in terms of mental health, education, language, race/ethnicity, and age.

A new protein-based vaccine candidate combined with a potent adjuvant provided effective protection against SARS-CoV-2 when tested in animals, suggesting that the combination could add one more promising COVID-19 vaccine to the list of candidates for human use.

Undeniably the shark movie to end all shark movies, the 1975 blockbuster, Jaws, not only smashed box office expectations, but forever changed the way we felt about going into the water - and how we think about sharks.

According to ARRS' American Journal of Roentgenology, return to routine screening for BI-RADS 3 lesions on supplemental automated whole-breast ultrasound (ABUS) substantially reduces the recall rate, while being unlikely to result in adverse outcome. This prospective study supports a recommendation for routine annual follow-up for BI-RADS 3 lesions at supplemental ABUS.

A research team at the Humboldt University Berlin and the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) developed an agent-based computer model to simulate the journey of sperm cells through the female genital tract. Key factors for a successful transit could be identified without the use of animal experiments and were published in the scientific journal "PLoS Computational Biology".

A massive study of data collected over 27 years has shown, for the first time on such a large scale, that a model hypothesizing that a process of social inheritance determines how offspring relationships are formed and maintained is correct. The study, published today in the journal Science, also elucidates the major role that social rank plays in structuring the spotted hyena clan, and how this affects survival.

The NIH funded academic institutions to design programs for professional development through "Broadening Experiences in Scientific Training" (BEST), which includes career panels, skill-building workshops, job-search workshops, site visits, and internships. Because doctoral training is lengthy and requires focused attention on research, some researchers feared students participating in additional training activities might diminish their research productivity or delay graduation. To find out if that was true, research staff from several leading institutions analyzed metrics from ten NIH BEST awardee institutions.

Scientist demonstrated a new way of observing atoms as they move in a tiny quantum electronic switch as it operates. Along the way, they discovered a new material state that could pave the way for faster, more energy-efficient computing.

Tufted titmice - tiny songbirds with exceptional memories - process spatial memory using mammalian-like neural mechanisms, researchers report.

Using mouse embryonic stem cells, researchers reconstituted ovarian follicle structures and used them to mature primordial germ cells into fully functional oocytes in vitro, which ultimately produced viable mouse offspring, according to a new report.
