Wildfire smoke has long been known to exacerbate health problems like heart disease, lung conditions, and asthma, but now a new study finds that smoke from these fires can lead to poor health thousands of miles away. Researchers found that medical visits for heart and lung problems rose by nearly 20 percent during six days in June, 2023, when smoke from Western Canadian wildfires drifted across the country, leading to...

Nearly all living organisms use the same genetic code, a complicated mechanism by which genetic information is translated into proteins, the building blocks of life. A new study suggests conventional wisdom about how the code evolved is likely flawed. Read more ›

For experiments that require ultra-precise measurements and control over atoms -- think two-photon atomic clocks, cold-atom interferometer sensors and quantum gates -- lasers are the technology of choice, the more spectrally pure (emitting a single color/frequency), the better. Conventional lab-scale laser technology currently achieves this ultra low-noise, stable light via bulky, costly tabletop systems designed to generate, harness and emit photons within a narrow spectral range.

A new analysis reveals that overfishing has caused populations of chondrichthyan fishes -- sharks, rays, and chimaeras -- to decline by more than 50 per cent since 1970. To determine the consequences, a team of researchers developed an aquatic Red List Index (RLI) which shows that the risk of extinction for chondrichthyan has increased by 19 per cent. The study also highlights that the overfishing of the largest species in... Read more ›

An international research team has controlled hybrid electron-photon quantum states in helium atoms. Control of these special quantum states was enabled by the pulse formation of very intense, extreme ultraviolet radiation. This method introduces the possibility not only of studying quantum mechanical effects in atoms and molecules, but also of controlling chemical reactions. Read more ›

Climate and land use change have and will continue to alter streamflow regimes and water quality through the 21st century, with consequences for drinking water treatment costs, flood protection, and other ecosystem services, according to the new report. The report is designed to inform forest sector decision-makers and the interested public about observed trends, anticipated futures, and critical issues based on authoritative synthesis and interpretation of existing science, data, and...

Leafy greens can become contaminated with pathogenic E. coli or other bacteria through splashes of soil or contaminated irrigation water in the field, or through processing and handling. Growers and processors work hard to implement multiple safety procedures, but contaminated products still slip through the cracks and reach consumers. A new study looks at control measures and product testing in the produce supply chain, aiming to determine the most effective... Read more ›

Stars similar to the Sun produce a gigantic outburst of radiation on average about once every hundred years per star. Such superflares release more energy than a trillion hydrogen bombs and make all previously recorded solar flares pale in comparison. This estimate is based on an inventory of 56450 sun-like stars. It shows that previous studies have significantly underestimated the eruptive potential of these stars. In data from NASA's space... Read more ›

Neanderthal genes make up 1-2% of the genomes of non-Africans. Scientists analyzed the lengths of regions of Neanderthal DNA in 58 ancient Eurasian genomes of early modern humans and determined that the introgressed genes result from interbreeding between Homo sapiens and Neanderthals about 47,000 years ago, over a single, extended period of about 7,000 years. The findings help pin down dates for out-of-Africa migration and the dispersal of Homo sapiens. Read more ›
