Though more than 131 million Americans have received at least one dose of COVID-19 vaccine to date, public confusion and uncertainty about the importance of second doses and continued public health precautions threaten to delay a U.S. return to normalcy, according to Cornell-led research published April 28 in the New England Journal of Medicine.

A new algorithm that taps data from a patient's electronic medical record can diagnose and stage chronic kidney disease, which is often undetected until it has caused irreversible damage.

The ability to turn on and off a physical process with just one photon is a fundamental building block for quantum photonic technologies. Realizing this in a chip-scale architecture is important for scalability, which amplifies a breakthrough by CCNY researchers led by physicist Vinod Menon. They've demonstrated for the first time the use of "Rydberg states" in solid state materials (previously shown in cold atom gases) to enhance nonlinear optical interactions to unprecedented levels in solid state systems.

A new paper written by Concordia researchers published in the Nature journal Scientific Reports used eye-tracking technology to record eye movements of readers and concluded that people with dyslexia have a profoundly different and much more difficult way of sampling visual information than normal readers.

Researchers at the University of Bonn and the research center caesar have succeeded in ultra-fast freezing proteins after a precisely defined period of time. They were able to follow structural changes on the microsecond time scale and with sub-nanometer precision. Owing to its high spatial and temporal resolution, the method allows tracking rapid structural changes in enzymes and nucleic acids. The results are published in the Journal of the American Chemical Society.

In an effort to fight the millions of tons of marine litter floating in the ocean, Florida State University researchers have developed a new virtual tool to track this debris. Their work, which was published in Frontiers in Marine Science, will help provide answers to help monitor and deal with the problem of marine litter.

A University of California San Diego engineering professor has solved one of the biggest mysteries in geophysics: What causes deep-focus earthquakes? These mysterious earthquakes originate between 400 and 700 kilometers below the surface of the Earth and have been recorded with magnitudes up to 8.3 on the Richter scale.

UArizona veterinary medicine associate professor Ryane Englar says that improving human interactions can also improve animal care.

UC Davis Comprehensive Cancer Center researchers found that targeting androgen receptors - a type of protein that is crucial for the function of testosterone - may destroy cancer cells. Focusing on this protein variant common in malignant bladder tumor cells may serve as a new avenue for treating bladder cancer in men.

The Southern Ocean dominates the oceanic uptake of human-made CO2. But how much carbon dioxide can it actually absorb in the future? This long-standing question remained unresolved as projections of different generation of climate models repeatedly showed a wide range of future Southern Ocean CO2 sink estimates. Climate scientists from Bern have now been able to reduce this large uncertainty by about 50 percent.

The results of a large, national heart attack study show that patients with a deadly complication known as cardiogenic shock survived at a significantly higher rate when treated with a protocol developed by cardiologists at Henry Ford Hospital in collaboration with four metro Detroit hospitals.

In a long-standing research project, an international research team led by the Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) has used lasers to excise and analyse the finest tissue parts involved in barley spikelet organ formation. The results are of immense importance for further comparative studies among other grass or cereal crops and have recently been published in the journal Science Advances.

The subseafloor constitutes one of the largest and most understudied ecosystems on Earth. An interdisciplinary research team, led from ASU and the Woods Hole Oceanographic Institution (WHOI), sought to learn more about this ecosystem by studying North Pond on the western flank of the mid-Atlantic Ridge, a plate boundary located along the floor of the Atlantic Ocean. They found microbes that were active and poised to eat.

New research shows that the variety of online players is shrinking rapidly, although the overall size of the worldwide web continues to expand and functional and geographic opportunities are rising.

Two teams have created a new generation of highly specific CAR T cells, which safely cleared solid tumors in mice with mesothelioma, ovarian cancer, and the deadly brain cancer glioblastoma while outlasting and outperforming conventional CAR T cell designs.

MIT researchers have uncovered a mechanism by which dissolved salts can crystallize in a way that makes it easy to remove them from surfaces, potentially helping to prevent fouling of metal surfaces.

Expanding the study of prehistoric permafrost thawing to North America, researchers found evidence in mineral deposits from caves in Canada that permafrost thawing took place as recently as 400,000 years ago, in temperatures not much warmer than today. But they did not find evidence the thawing caused the release of predicted levels of carbon dioxide stored in the frozen terrain.

Earth's permafrost shifted to a more stable state in the last 400,000 years and has been less susceptible to thawing since then, according to a new study by MIT researchers and their colleagues.

In wild soil, bacteria that eat other bacteria consume more resources and grow faster than their prey, a new study from Northern Arizona University finds. The results of the study, published in the journal mBio this week, show predation is an important dynamic in the wild microbial realm, and suggest that these predators play an outsized role in how elements are stored in or released from soil.

Scientists at Tokyo Institute of Technology (Tokyo Tech) have recently published the results of their investigations into adaptive radiation, which is when organisms rapidly evolve from an ancestral species into novel forms. Their genetic analyses of cichlids in Lake Victoria highlight several candidate genes that may drive adaptive radiation and provide evidence for decisive selective events that cause particular genetic variants to quickly gain dominance within populations. These findings broaden scientific understanding of how new species arise.
