Three currently circulating omicron subvariants of SARS-CoV-2 are better at evading vaccine- and infection-generated neutralizing antibodies than earlier versions of omicron, new research suggests.
Adolescence is a time of significant skeletal development. In a new report, researchers showed that long-term use of minocycline, an antibiotic used for the systemic treatment of adolescent acne, disrupts the normal gut microbiome, leading to poor bone maturation. Surprisingly, these effects were caused by a change in the gut microbiome, leading to an altered profile of bile acids -- molecules...
The Indo-Pacific region is a convergence zone with the largest biodiversity in the global ocean. However, previous models were not refined enough to resolve the complex topography of main straits.
Various chemical products, such as polymers and pharmaceutical intermediates, are currently synthesized with phosgene as their precursor or raw material. However, phosgene is highly toxic and this usage poses safety risks. Thus, there is demand for the development of new methods and substitutes to replace phosgene.
The James Webb Space Telescope (JWST) has just scored another first: a detailed molecular and chemical portrait of a distant world's skies.
Joi Mitchell fell into tutoring largely by accident, but in retrospect it all makes sense. The 27-year-old grew up in a family of educators in Chicago. After college, where she majored in business administration, some of her roles involved mentoring teens.
Physicists have long struggled to explain why the universe started out with conditions suitable for life to evolve. Why do the physical laws and constants take the very specific values that allow stars, planets and ultimately life to develop? The expansive force of the universe, dark energy, for example, is much weaker than theory suggests it should be—allowing matter to clump together rather...
New research at the University of Chicago has found that the same machinery used by mammalian cells to drive cellular differentiation also plays a critical role in activating genes in yeast in response to environmental stress.
Analysis challenges WHO health guidance on amount of time women should delay after miscarriage or abortionWomen don’t need to wait for at least six months before trying for another baby after a miscarriage or abortion, an analysis of data suggests, challenging World Health Organization guidance.The research was also at odds with WHO advice that women should delay at least 24 months after a live...
Superconducting materials are characterized by the fact that they lose their electrical resistance below a certain temperature, the so-called transition temperature. In principle, they would be ideal for transporting electrical energy over very long distances from the electricity producer to the consumer.
Around the world, governments have widely attempted two strategies meant to reduce the use of gasoline by making it more expensive.
Dr. Benjamin Rotstein and collaborators unveil an operationally simple method to prepare carbon isotope-labeled versions of drugs and diagnostics.
Plant landing is a major event during evolution. Accompanying their movement from aquatic to terrestrial habitats, different evolutionary plant lineages have evolved distinct characteristic body plans and anatomical structures, which have conferred on plants the adaptive ability to explore new environments.
Biophysicists from the University of Luxembourg have uncovered how microplankton—key photosynthetic organisms which produce nearly 50% of the oxygen we breathe—adopt a thrifty lifestyle when nutrients turn limiting. They strategically harness internal lipids to regulate swimming properties to maximize their fitness.
The world could still, theoretically, meet its goal of keeping global warming under 1.5 degrees Celsius, a level many scientists consider a dangerous threshold. Realistically, that's unlikely to happen.
Physicist who played a key role from the birth of particle physics in the 1940s to the discovery of the Higgs bosonThe particle physicist Donald Perkins, who has died aged 97, made seminal discoveries about the structure of the proton, and nuclear interactions at extreme energies, and first proposed the use of beams of pion particles in cancer therapy. His career spanned the birth of particle...
South Africa is famous for its amazingly rich and diverse fossil record. The country's rocks document more than 3.5 billion years of life on Earth: ancient forms of bacterial life, the emergence of life onto land, the evolution of seed-producing plants, reptiles, dinosaurs and mammals—and humanity.
The Sun is much more than just a source of light for Earth—it's a dynamic and complex star, with storms, flares, and movement causing it to change constantly. Magnetic fields govern most of the solar activity we can observe but how they do this is still poorly understood. New results based on simulations out of NASA's Advanced Supercomputing facility at NASA's Ames Research Center in...
Improving supports for older adults who experience homelessness in three major Canadian cities is the focus of an ongoing study being led by Simon Fraser University adjunct professor Sarah Canham.
Citizen science is touted as a way for the general public to contribute to producing new knowledge. But citizen science volunteers don't always represent a broad cross-section of society. Rather, they're often white, male, middle-aged, educated and already interested in science.
Few things say summer in America more than buttery corn on the cob, but as summer temperatures climb to unprecedented levels, the future of sweet corn may not be so sweet. New University of Illinois research shows sweet corn yields drop significantly with extreme heat during flowering, especially in rainfed fields in the Midwest.
A new study has revealed how the glass-like shells of diatoms help these microscopic organisms perform photosynthesis in dim conditions. A better understanding of how these phytoplankton harvest and interact with light could lead to improved solar cells, sensing devices and optical components.
A large Adélie penguin population off Antarctica has fallen by 43% over the past decade.
