Among people who have strokes and COVID-19, there is a higher incidence of severe stroke as well as stroke in younger people, according to new data from a multinational study group on COVID-19 and stroke, led by a team of Geisinger researchers.

Florida Museum of Natural History researchers analyzed CT scans of nearly every living amphibian genus to reveal that frogs have lost teeth over 20 times during their evolution, more than any other vertebrate group.

In recent months, more than three hundred cases of salmonellosis have occurred in various European countries and Canada, which are linked to each other. In the UK the cases could be partly traced back to frozen breaded poultry meat. The cause was contamination with the bacterium Salmonella Enteritidis, which causes gastrointestinal inflammation. Salmonella is not killed by deep freezing and can remain infectious at temperatures below zero degrees Celsius.

A college education is estimated to add $1 million to a person's lifetime earning potential, but for some students the path to earning one is riddled with obstacles. That journey is even more difficult for students who have been in the foster care system or experienced homelessness, according to a new study from the University of Georgia.

A new miniature 3D model of human bone marrow has been described today in the open-access eLife journal. The model may help clinicians predict which patients will benefit from a new therapy for blood platelet disorders, such as Inherited Thrombocytopenias -- a group of familial disorders that inhibit the production of platelets. It could also enable further study of these disorders and give scientists a new tool to test experimental treatments.

News media reports about scientific failures that do not recognize the self-correcting nature of science can damage public perceptions of trust and confidence in scientific work, according to findings of a study by researchers at the Annenberg Public Policy Center of the University of Pennsylvania and the University at Buffalo, the State University of New York.

Corvids use social information to protect themselves against deception by conspecifics from neighboring territories.

Swedish researchers from institutions including Uppsala University have spent four years gathering data from the areas affected by the major forest fire of 2014. In their study of how the ecosystem as a whole has been altered, they could see that water quality in watercourses quickly returned to normal, while forested areas continued to lose carbon for many years after the fire.

The first 2D mica resistive random access memory (RRAM) device has been demonstrated, which exhibit unique non-Markov chain characteristic. The migration of inner K+ in mica under electrical field is responsible for this unique transport behavior. Our work shows great potential of 2D mineral materials for electronics.

Getting enough sleep can be a real challenge for shift workers affecting their overall health. But what role does being an early bird or night owl play in getting good rest? Researchers from McGill University find a link between chronotype and amount of sleep shift workers can get with their irregular schedules.

Scientists at Tokyo Institute of Technology (Tokyo Tech) created a novel type of material that combines the structural flexibility of van der Waals materials with the endless tuning possibilities of high-entropy alloys. In their paper, they explore the properties of these new materials and the many promises they hold in electronics applications.

Researchers at Children's Hospital of Philadelphia (CHOP) have developed a proof-of-concept treatment for blood disorders like sickle cell disease and beta-thalassemia that could raise hemoglobin levels by activating production of both fetal and adult hemoglobin. Using a viral vector engineered to reactivate fetal hemoglobin production, suppress mutant hemoglobin, and supply functional adult hemoglobin, the researchers developed an approach that could produce more hemoglobin through a single vector. The results were published in Haematologica.

Creating and manipulating multiple charge states of a single atomic defect in semiconductors is of essential importance to "qubits" of solid-state quantum computation, but fundamentally limited by Coulomb's law. The object is challenged by the conflicting requirements of localization for sizable band gap and delocalization for low charging energy. Recently, researchers from China and Singapore realized exotic quinary charge states of single defect in two-dimensional intermetallic semiconductor Sn2Bi, and observed an ultralow defect charging energy.

ORNL story tips: Un-Earthly ice, buildings in the loop, batteries unbound and 3D printing for geothermal.

The Treatabolome project is a research initiative to develop a freely available, interoperable online platform to disseminate rare disease and gene-specific treatment information to healthcare professionals regardless of their level of specialized expertise to reduce treatment delays. This initiative is highly relevant to neuromuscular disorders as they are rare diseases by definition. In this special issue of the Journal of Neuromuscular Diseases, experts contribute Treatabolome-feeding systematic literature reviews on rare neurological and neuromuscular disorders.

Researchers have developed a new state-of-the-art method for controlling how artificial intelligence (AI) systems create images. The work has applications for fields from autonomous robotics to AI training.

A new type of penile traction therapy (PTT) device can increase penile length and preserve erectile function in men who have undergone prostate cancer surgery (prostatectomy), reports a clinical trial in The Journal of Urology®, Official Journal of the American Urological Association (AUA). The journal is published in the Lippincott portfolio by Wolters Kluwer.

The German-French Cooperation Programme GENESIS describes the complex structure of the interstellar medium using a new mathematical method. The dispersion of interstellar turbulence in gas clouds before star formation unfolds in a cosmically small space.

Ozone depletion following the Toba eruption around 74,000 years ago compounded the ensuing volcanic winter and caused a human population bottleneck.

New findings from scientists of Bremen will aid in the further development of biogeochemical models that include the marine nitrogen cycle
