Escape the vapes: Scientists call for global shift to curb consumer use of disposable technologies
Scientists have called for a concerted global effort to stem the tide of disposable electronic technologies—such as vapes—contributing to international waste accumulation and environmental degradation......»»
Yeast study offers possible answer to why some species are generalists and others specialists
In a landmark study based on one of the most comprehensive genomic datasets ever assembled, a team led by scientists at the University of Wisconsin–Madison and Vanderbilt University offer a possible answer to one of the oldest questions about evolu.....»»
Scientists say voluntary corporate emissions targets not enough to create real climate action
Companies' emissions reduction targets should not be the sole measure of corporate climate ambition, according to a new perspective paper......»»
How much trust do people have in different types of scientists?
Understanding why some people trust some scientists more than others is a key factor in solving social problems with science. But little was known about the trust levels across the diverse range of scientific fields and perspectives......»»
Study demonstrates efficacy of web programming course for incarcerated individuals
Several years ago, a team of scientists from MIT and the University of Massachusetts at Lowell designed and deployed a first-of-its-kind web programming course for incarcerated individuals across multiple correctional facilities. The program, Brave B.....»»
Scientists use "leaf glow" to understand changing climate
New University of Minnesota research suggests "leaf glow" provides vital information on vegetation dynamics in Arctic and boreal ecosystems like Minnesota's forests and wetlands, which are among the fastest warming in the world. Using remote sensing.....»»
Did climate chaos cultivate or constrain 2023"s greenery?
In the ongoing quest to track the progression of climate change, scientists frequently examine the state of our planet's vegetation—forests, grasslands, agricultural lands, and beyond......»»
Scientists combine a spatially distributed sediment delivery model and biogeochemical model to estimate fluxes by water
Water erosion is the most active process controlling soil formation and evolution, which can affect the redistribution of carbon between terrestrial, aquatic, and atmospheric ecosystems. Erosion-induced organic carbon dynamic process should not be mi.....»»
Scientists regenerate neural pathways in mice with cells from rats
Two independent research teams have successfully regenerated mouse brain circuits in mice using neurons grown from rat stem cells. Both studies, published April 25 in the journal Cell, offer valuable insights into how brain tissue forms and present n.....»»
Solar geoengineering to cool the planet: Is it worth the risks?
When I first wrote about geoengineering in 2012 , it was considered far-fetched at best, and crazy by most. But 12 years later, while there is still controversy and considerable resistance to deploying it, respectable scientists and institutions are.....»»
Study says it"s likely a warmer world made deadly Dubai downpours heavier
Circumstantial evidence points to climate change as worsening the deadly deluge that just flooded Dubai and other parts of the Persian Gulf, but scientists didn't discover the definitive fingerprints of greenhouse gas-triggered warming they have seen.....»»
Scientists replace fishmeal in aquaculture with microbial protein derived from soybean processing wastewater
Scientists from Nanyang Technological University, Singapore (NTU Singapore) and Temasek Polytechnic have successfully replaced half of the fishmeal protein in the diets of farmed Asian seabass with a "single cell protein" cultivated from microbes in.....»»
