What The Study Did: Among children with a COVID-19 diagnosis, researchers in this study examined what other conditions are common and which are associated with severe COVID-19 illness.

What The Study Did: In this study, short-term effectiveness of the first dose of the BNT162b2 (BioNTech/Pfizer) vaccine against SARS-CoV-2 infection 13 to 24 days after immunization in a real-world setting was assessed.

Physicists led by the University of Iowa report definitive evidence of how auroras are created. In experiments, the physicists demonstrated the physical mechanisms for the acceleration of electrons by Alfven waves under conditions corresponding to Earth's auroral magnetosphere. Results appear in the journal Nature Communications.

Bdelloid rotifers are multicellular animals so small you need a microscope to see them. Despite their size, they're known for being tough, capable of surviving through drying, freezing, starvation, and low oxygen. Now, researchers reporting in the journal Current Biology on June 7, 2021 have found that not only can they withstand being frozen, but they can also persist for at least 24,000 years in the Siberian permafrost and survive.

Jet packs, robot maids and flying cars were all promises for the 21st century. We got mechanized, autonomous vacuum cleaners instead. Now a team of Penn State researchers are exploring the requirements for electric vertical takeoff and landing (eVTOL) vehicles and designing and testing potential battery power sources.

The fluorescence dyes were the dominant species of the near-infrared (NIR) dyes, but the energy gap of the NIR dyes between S1 and S0 is generally small to induce the ultrafast internal conversion dynamics to quench the NIR emission of the fluorescence dyes. Here, scientists based in China proposed a new assumption to construct efficient NIR materials based on the metal-free room-temperature phosphorescence materials, and a series of NIR materials were reported for the demonstration of the assumption.

A minimally invasive procedure that targets the nerves near the kidney has been found to significantly reduce blood pressure in hypertension patients, according to the results of a global multicenter clinical trial led in the UK by researchers at Queen Mary University of London and Barts Health NHS Trust.

How basic physics and chemistry constrain cellular functions in primitive and modern cells.

The study revealed extremely high genetic diversity in the Euphaea yayeyamana in Ishigaki and Iriomote. The genetic diversity within Taiwan's population of Euphaea formosa was significantly lower than that within either Ishigaki or Iriomote islands despite Taiwan being significantly larger with a diverse array of habitats including high mountain ranges that reach 4,000 meters above sea level.

Older people need digital skills training to learn to use digital technology more independently, but they also seek digital training opportunities because of the social benefits they offer, according to a recent study from the University of Eastern Finland.

Decades of research has revealed the remarkable morphological adaptations of sea snakes to aquatic life, which include paddle-shaped tails, salt-excreting glands, and the ability to breathe through their skin. In a new study published in Biological Journal of the Linnean Society, researchers at the University of Adelaide detail the enlarged touch receptors that evolved in male turtle-headed sea snakes (Emydocephalus annulatus), to help them locate and court females in aquatic environments.

A team of astronomers from the National Centre for Radio Astrophysics (NCRA-TIFR), Pune, and the Raman Research Institute, Bangalore, used the Giant Metrewave Radio Telescope to measure the atomic hydrogen gas content of galaxies 9 billion years ago. The new result is a confirmation of the group's earlier result, where they had measured the atomic hydrogen content of galaxies 8 billion years ago, and pushes our understanding of galaxies to even earlier in the universe.

A research team from the University of Copenhagen and University of Helsinki demonstrates it is possible to predict individual preferences based on how a person's brain responses match up to others. This could potentially be used to provide individually tailored media content -- and perhaps even to enlighten us about ourselves.

New research suggests that measuring how patterns of gene expression in white blood cells change in children starting in infancy - before autoantibodies appear indicating an autoimmune reaction against pancreatic β cells - can predict earlier and more robustly which genetically-susceptible individuals will progress to T1D. The international study, based on blood samples longitudinally collected from 400 children in The Environmental Determinants of Diabetes in the Young (TEDDY) consortium, included co-investigators from the University of South Florida Health Informatics Institute.

No one knows what happened in the universe for its first 400,000 years, but a new paper suggests discovering the hypothetical particle axion could shed light on the early history of the universe. What's more, current dark matter experiments may have already detected it in its data.

When we inhale isolated coronavirus particles, more than 65% reach the deepest region of our lungs, new research has discovered, and more of these aerosols reach the right lung than the left.

Monash University researchers have provided a fundamental advance regarding how T cells become activated when encountering pathogens such as viruses.

A preclinical study led by scientists at Sanford Burnham Prebys has established that AAV8-TNAP-D10--a gene therapy that replaces a key enzyme found in bone--may be a safe and effective single-dose treatment for hypophosphatasia (HPP). The study, published in the Journal of Bone and Mineral Research and performed in a murine model of the disease, further supports advancing the therapy toward human clinical trials.

A world-first international study led by the University of South Australia has identified a new drug to stop athletes developing dementia after sustaining repeated head injuries in their career.

Wider clean chemistry applications of the extraordinary Vortex Fluidic Device -- invented by Flinders University's Professor Colin Raston -- are likely in the wake of new research that has been published outlining the seemingly endless possible uses.The defining paper on understanding fluid flow in the Vortex Fluidic Device has just been comprehensively explained in an article published in Nanoscale Advances.
