What The Study Did: Researchers estimated the extent Medicare Part B medical services would have been subject to prior authorization under private insurance coverage policies and calculated the associated spending.

What The Study Did: This survey study examined the associations of having an incarcerated immediate or extended family member with perceived well-being and change in projected life expectancy among adults in the United States.

What The Study Did: Study results suggest that reinfections are rare events and that patients who have recovered from COVID-19 have a lower risk of reinfection. However, the observation ended before SARS-CoV-2 variants began to spread, and it is unknown how well natural immunity to the wild-type virus will protect against variants.

What The Study Did: Socioeconomic disparities in respiratory health over the past six decades in the United States are described in this study.

What The Study Did: This study evaluates whether there are differences in SARS-CoV-2 seroprevalence and antibody levels in patients with cancer compared with health care workers in Japan.

What The Study Did: Rates of antispike antibody response to a messenger RNA SARS-CoV-2 vaccine in Israeli patients with cancer who are undergoing systemic treatment compared with healthy controls were evaluated in this study.

Scientists from the Cluster of Excellence ct.qmat - Complexity and Topology in Quantum Matter have developed a new understanding of how electrons behave in strong magnetic fields. Their results explain measurements of electric currents in three-dimensional materials that signal a quantum Hall effect - a phenomenon thus far only associated with two-dimensional metals.

When San Francisco voters overwhelmingly approved a ballot measure banning the sale of flavored tobacco products in 2018, public health advocates celebrated. After all, tobacco use poses a significant threat to public health and health equity, and flavors are particularly attractive to youth.

The ancient burrowers of the seafloor have been getting a bum rap for years.These prehistoric dirt churners -- a wide assortment of worms, trilobites, and other animals that lived in Earth's oceans hundreds of millions of years ago -- are thought to have played a key role in creating the conditions needed for marine life to flourish. Their activities altered the chemical makeup of the sea itself and the amount of oxygen in the oceans, in a process called bioturbation.

A research team co-led by a scientist from City University of Hong Kong (CityU) has designed a simple electromechanical device that can be used for deep tissue pathology diagnosis, such as psoriasis, in an automated and non-invasive fashion. The findings will lay a foundation for future applications in the clinical evaluation of skin cancers and other dermatology diseases.

Dark Matter Particle Explorer (DAMPE) Collaboration directly observed a spectral softening of helium nuclei at about 34TeV for the first time.

Balfour Sartor, MD, Midget Distinguished Professor of Medicine, Microbiology and Immunology, is the senior author of a study that shows how a novel consortium of bacteria that live in the digestive tracts of healthy individuals can be used to prevent and treat aggressive colitis in humanized mouse models.

Research team of Samara Polytech in cooperation with the crystallographic research group of Lomonosov Moscow State University studied non-racemic 4,5-dihydrofurans.

1. Development of a two-photon excitation light-sheet microscope which achieves low phototoxicity, an extended field of view, and high resolution for the observation of the growth of living organisms2. Applications of the microscope demonstrate long-term time-lapse observations for a three-day span of the embryonic development of medaka fish

The work was conducted under the auspices of the Russian Foundation for Basic Research and organizations-participants of the BRICS framework program in science, technology and innovation; the grant title is "Nanosized peptide-based biomaterials for photodynamic diagnostics of tumors".

An international archaeological study, led by researchers from the Culture and Socio-Ecological Dynamics (CaSEs) research group, has advanced in the understanding and preservation of archaeological sites and in improving their analysis, thanks to the application of pXRF (portable X-ray fluorescence analysis) to anthropogenic sediments in Africa. It is a rapid, inexpensive, non-invasive procedure, which enables generating an additional archaeological record from the anthropogenic deposit by analysing chemical elements, combined with geostatistics.

During the era of commercial whaling, fin whales were hunted so intensively that only a small percentage of the population in the Southern Hemisphere survived, and even today, marine biologists know little about the life of the world's second-largest whale.

Researchers designed a alloy comprised of cheap and earth-abundant metal element with better efficiency than traditional platinum-based anode and time endurance to boost the commercialization of hydrogen energy.

Metal-organic framework compounds (MOFs) are widely used in gas storage, material separation, sensor technology or catalysis. A team led by Prof. Dr. Stefan Kaskel, TU Dresden, has now investigated a special class of these MOFs at the MX beamlines of BESSY II. These are "switchable" MOFs that can react to external stimuli. Their analysis shows how the behaviour of the material is related to transitions between ordered and disordered phases. The results have now been published in Nature Chemistry.

Researchers have combined two or three types of nanoparticles to produce new materials with structures known as superlattices. In some instances, the structures display fundamental new properties such as superfluorescence. The researchers' discovery is reported in the journal Nature and featured on the current issue's cover.
