Surprise climate bill will meet ambitious goal of 40% cut in U.S. emissions, energy models predict

For climate advocates in the United States, the past month felt like a roller coaster. In early July, negotiations in Congress on clean energy legislation of historic proportions collapsed, and the effort seemed doomed. But backroom talks continued and last week key senators suddenly announced an agreement on a $369 billion bill that would provide the most climate funding...

Study finds cable news networks have grown more polarized

Even though it seems that Americans are constantly on their phones, studies have shown that the majority of Americans still get their news from television. At the beginning of 2020, the average American adult consumed around nine-and-a-half hours of television news per week, according to Nielsen.

AI can reveal new cell biology just by looking at images

Humans are good at looking at images and finding patterns or making comparisons. Look at a collection of dog photos, for example, and you can sort them by color, by ear size, by face shape, and so on. But could you compare them quantitatively? And perhaps more intriguingly, could a machine extract meaningful information from images that humans can't?

Signaling 'stressed-out' plants

As plants experience multiple stressors from heat, drought and flooding because of extreme weather events, a plant scientist recently discovered a new way of measuring whether they are stressed out.

Research finds mechanically driven chemistry accelerates reactions in explosives

Scientists at the Lawrence Livermore National Laboratory (LLNL) Energetic Materials Center and Purdue University Materials Engineering Department have used simulations performed on the LLNL supercomputer Quartz to uncover a general mechanism that accelerates chemistry in detonating explosives critical to managing the nation's nuclear stockpile. Their research is featured in the July 15 issue of...

What's new under the sun? Offering an alternate view on how 'novel' structures evolve

New research provide evidence that the crustacean carapace, along with other plate-like structures in arthropods (crustaceans, insects, arachnids, and myriapods) all evolved from a lateral leg lobe in a common ancestor more than 500 million years ago. This work further supports their proposal for a new concept of how novel structures evolve -- one which suggests that they aren't so novel, after...

Climate endgame: risk of human extinction ‘dangerously underexplored’

Scientists say there are ample reasons to suspect global heating could lead to catastropheThe risk of global societal collapse or human extinction has been “dangerously underexplored”, climate scientists have warned in an analysis.They call such a catastrophe the “climate endgame”. Though it had a small chance of occurring, given the uncertainties in future emissions and the climate...

Legacy of ancient ice ages shapes how seagrasses respond to environmental threats today

Deep evolution casts a longer shadow than previously thought, scientists report in a new paper published the week of Aug. 1 in the Proceedings of the National Academy of Sciences. Smithsonian scientists and colleagues looked at eelgrass communities—the foundation of many coastal marine food webs along the north Atlantic and Pacific coasts—and discovered their ancient genetic history can play a...

Automating neutron experiments with AI

Oak Ridge National Laboratory researchers are developing a first-of-its-kind artificial intelligence device for neutron scattering called Hyperspectral Computed Tomography, or HyperCT. The fully automated, AI-driven platform can rotate a sample in almost any direction, eliminating the need for human intervention and significantly reducing lengthy experiment times.

Fires increase in Brazilian Amazon in July

The number of forest fires in the Brazilian Amazon increased by eight percent last month compared with July 2021, according to official figures released Monday, the latest alarm bell for the world's biggest rainforest.
