Traditionally, it has been assumed that cultivating food leads to a loss of biodiversity and negative impacts on an ecosystem. A new study defies this assumption, showing that community gardens and urban farms positively affect biodiversity, local ecosystems and the well-being of humans that work in them.

We love our chicken. We love our salmon. Thanks to how we farm these two popular proteins, their environmental footprints are surprisingly similar.

Researchers chiral phonons to convert wasted heat into spin information -- without needing magnetic materials. The finding could lead to new classes of less expensive, energy-efficient spintronic devices for use in applications ranging from computational memory to power grids.

Santa Barbara Channel's natural oil seeps are a beach-goer's bane, flecking the shores with blobs of tar. But the leaking petroleum also creates fascinating geologic and biologic features. About 10 miles off the coast of Santa Barbara, several jet-black mounds interrupt the featureless sea floor. These asphalt volcanoes, virtually unique in the world, provide a rare habitat in a region known for its underwater biodiversity.

A new study finds that a 200-year-old technique called Fourier analysis can reveal crucial information about how the form of artificial intelligence called deep neural networks (DNN) learn to perform tasks involving complex physics. Researchers discovered the technique can directly connect what a DNN has learned to the physics of the complex system the DNN is modeling.

Scientists have created a new technology to assemble matter in 3D. Their concept uses multiple acoustic holograms to generate pressure fields with which solid particles, gel beads and even biological cells can be printed. These results pave the way for novel 3D cell culture techniques with applications in biomedical engineering.

When patients receive care after cardiac arrest, doctors can now -- by entering patient data in a web-based app -- find out how thousands of similar patients have fared. Researchers have developed three such systems of decision support for cardiac arrest that may, in the future, make a major difference to doctors' work.

Bee researchers have identified a new gene in honeybees, which is responsible for the dimorphic eye differentiation between males and females of the species. The researchers have now presented this gene and the evolutionary genetic conclusions they have drawn from it.

New research proposes a funding model for a major rehabilitation of the 27 locks and dams on the Upper Mississippi. It relies on a collective investment from all -- or at least most -- of the shippers, along with government funding. The researcher's model shows the public-private partnership would pay off in the long run.

The idea that forest trees can 'talk' to each other, share resources with their seedlings -- and even protect them -- through a connective underground web of delicate fungal filaments tickles the imagination. The concept is so intriguing, it's taken root in popular media -- even being raised in the popular Apple TV show Ted Lasso -- and been dubbed the 'wood-wide web,' but the science behind those ideas is unproven, cautions an expert.

Aetosaurs had a small head and a crocodile-like body. The land dwellers were up to six meters long and widely distributed geographically. They died out about 204 million years ago, at the end of the Triassic. In Germany, an assemblage of 24 Aetosaurus ferratus individuals, only between 20 and 82 centimeters long, was discovered in 1877. Since then, scientists have been puzzling over whether they were juveniles or small adults. A team has now solved the mystery: Bone examination of two specimens shows that they are juveniles.

Researchers have used an innovative new strategy combining nuclear magnetic resonance imaging and a quantum modeling theory to describe the microscopic structure of Kagome superconductor RbV3Sb5 at 103 degrees Kelvin, which is equivalent to about 275 degrees below 0 degrees Fahrenheit.

Computer software can predict what happens to complex gene networks when individual genes are missing or dialed up more than usual. Mapping the roles of single genes in these networks is key to understanding healthy development and finding ways to regrow damaged cells and tissues. Understanding genetic errors could provide insight into birth defects, miscarriage or even cancer.

Goffin's cockatoos have been added to the short list of non-human animals that use and transport toolsets. Researchers show that the cockatoos carry multiple tools to their worksite when the job calls for it. This behavior has only been previously reported in chimpanzees, our closest relatives.
