Turning mixed plastic into useful chemicals

Almost 80% of plastic in the waste stream ends up in landfills or accumulates in the environment. Oak Ridge National Laboratory scientists have developed a technology that converts a conventionally unrecyclable mixture of plastic waste into useful chemicals, presenting a new strategy in the tool kit to combat global plastic waste.

NASA team simulates a glimpse of our galaxy in gravitational waves

Astronomers using simulated data have produced a glimpse of the sky as it would appear in gravitational waves, cosmic ripples in space-time generated by orbiting objects. The image shows how space-based gravitational wave observatories expected to launch in the next decade will enhance our understanding of our galactic home.

Exploring the mind-mitochondria connection

As befits the child of a scientist, Martin Picard's young son, 3, is already learning about biology with an age-appropriate textbook, "Cell Biology for Babies." Picard winces a little whenever the book calls mitochondria the "powerhouses of the cell" but figures he has plenty of time as his son grows older to explain why the tiny organelles are much more than simple energy sources.

How do zeolite-encapsulated metal catalysts act on hydrogen-related catalytic reactions?

Zeolites encapsulated metal and metal oxide species (regarded as metal@zeolite) are an important type of heterogeneous catalyst. They give performances that steadily outperform the traditional supported catalysts in many important reactions and have become a research hotspot. Remarkable achievements have been made dealing with the synthesis, characterization, and performances of metal species...

Unveiling the aquatic marvel: The rock-climbing fish and its adhesion-sliding feat

Underwater "traffic" encompasses a fascinating variety of creatures, from fish with their graceful swimming postures to jet-propelled jellyfish and remoras hitching rides on other organisms. Among these, a remarkable species known as the "underwater gecko," the rock-climbing fish (Beaufortia kweichowensis), stands out. This extraordinary creature possesses a unique set of abilities—it can...

Incentive programs doubled cover crop use by farmers: Study

A survey of farmers in four Northeast states, including New York, found that incentive payments encouraged participants to plant twice as many acres of cover crops as they did prior to receiving funds—a change that can both improve their farms and mitigate climate change.

Ensuring effective visual communication of climate change

The consequences of a warming climate frequently dominated the news this summer, from devastating wildfires and floods to deadly heat waves across the globe. Reducing harm from climate change is a challenging endeavor, and it requires comprehensive public education. Thus, the question arises: How can climate change science be made most accessible to the general population, as well as...

Ancient Amazonians created mysterious ‘dark earth’ on purpose

Mysterious patches of fertile black soil pepper the verdant Amazon rainforest. They sit in stark contrast with the reddish, eroded soil that dominates the basin. Researchers have long thought this Amazonian dark earth—or terra preta —was created by pre-Hispanic Indigenous civilizations, which have inhabited the region for millennia, but it wasn’t clear how. Now, a...
