A pair of orbiting black holes millions of times the Sun's mass perform a hypnotic pas de deux in a new NASA visualization. The movie traces how the black holes distort and redirect light emanating from the maelstrom of hot gas - called an accretion disk - that surrounds each one.
Financial stress can have an immediate impact on well-being, but can it lead to physical pain nearly 30 years later? The answer is yes, according to new research.
Researchers have discovered a novel way to improve the performance of electrical wires used as high-temperature superconductors (HTS), findings that have the potential to power a new generation of particle accelerators.
Australian pineapple, Danish trout, and Midwestern U.S. corn farmers are not often lumped together under the same agricultural umbrella. But they and many others who raise crops and animals face a common problem: excess nitrogen in drainage water. Whether it flows out to the Great Barrier Reef or the Gulf of Mexico, the nutrient contributes to harmful algal blooms that starve fish and other...
Reliance on petroleum fuels and raging wildfires: Two separate, large-scale challenges that could be addressed by one scientific breakthrough. Researchers have developed a streamlined and efficient process for converting woody plant matter like forest overgrowth and agricultural waste - material that is currently burned either intentionally or unintentionally - into liquid biofuel.
Researchers have developed a method that uses machine learning, satellite imagery and weather data to autonomously find hotspots of heavy air pollution, city block by city block. The technique could be a boon for finding and mitigating sources of hazardous aerosols, studying the effects of air pollution on human health, and making better informed, socially just public policy decisions.
In order to get a sense of what our future may hold, scientists have been looking to the deep past. Now, new research from the University of Massachusetts Amherst, which combines climate, ice sheet and vegetation model simulations with a suite of different climatic and geologic scenarios, opens the clearest window yet into the deep history of the Antarctic ice sheet and what our planetary future...
Amyloid fibrils are deposits of proteins in the body that join together to form microscopic fibres. Their formation has been linked to many serious human diseases including Alzheimer's, Parkinson's and Type 2 diabetes.
Researchers at Duke University have developed a method that uses machine learning, satellite imagery and weather data to autonomously find hotspots of heavy air pollution, city block by city block.

Agricultural producers deal firsthand with changing weather conditions, and extreme events such as drought or flooding can impact their productivity and profit. Climate change models project such events will occur more often in the future. But studies of the economic consequences of weather and climate on agriculture typically focus on local impacts only.
Three of the largest forestry companies operating in northwestern Ontario say an environmental group's criticisms of logging practices in Ontario and Quebec are...
An environmental group filed a lawsuit Thursday alleging the federal government has failed to act on petitions to protect nine species under the Endangered Species Act and has failed to designate critical habitat for 11 other species that are already protected.
As muddy rainwater surged from Hawaii's steep seaside mountains and inundated residential communities last month, the damage caused by flooding was obvious—houses were destroyed and businesses swamped, landslides covered highways and raging rivers and streams were clogged with debris.
Experts calculate the total number of the dinosaurs that lived over 127,000 generationsOne Tyrannosaurus rex seems scary enough. Now picture 2.5 billion of them. That’s how many of the fierce dinosaur king probably roamed Earth over the course of a couple of million years, a new study finds.Using calculations based on body size, sexual maturity and the creatures’ energy needs, a team at the...
Scientists confirm they have made "chimera" embryos from long-tailed macaques and humans.
The Google Earth app is adding a new video feature that draws upon nearly four decades of satellite imagery to vividly illustrate how climate change has affected glaciers, beaches, forests and other places around the...
A warmer winter and pandemic public health restrictions may be contributing to more rat sightings in Nova Scotia.

Last month saw the average concentration of atmospheric carbon dioxide (CO2) climb to almost 418 parts-per-million, a level not seen on Earth for millions of years. In order to get a sense of what our future may hold, scientists have been looking to the deep past. Now, new research from the University of Massachusetts Amherst, which combines climate, ice sheet and vegetation model simulations with...
Florida State University researchers have discovered a novel way to improve the performance of electrical wires used as high-temperature superconductors (HTS), findings that have the potential to power a new generation of particle accelerators.
A new study from North Carolina State University found that, on average, voters and local leaders showed greater concern about plastic and other garbage in the ocean after watching kids' presentations.
