From lab-grown chicken to cricket-derived protein, these innovative alternatives offer hope for a planet struggling with the environmental and ethical impacts of industrial agriculture. Now, scientists add a new recipe to the list -- cultured beef rice -- by growing animal muscle and fat cells inside rice grains. The method results in a nutritious and flavorful hybrid food that, once commercialized, could offer a more affordable protein alternative with a smaller carbon footprint.

Researchers have developed a new nanoparticle that can 'hitch a ride' on immune cells, or monocytes. Because of its tiny size, the particle can tag along directly into lymph nodes and help metastasis show up on MRIs where it would otherwise be too hard to detect. The process offers game-changing benefits for the early detection of cancer metastasis in the lymph nodes. While previously, metastasis could only be assessed by an increase in lymph node size; the new particles could lead to MRI contrast agents that can highlight metastatic cells in lymph nodes that may otherwise appear normal.

As temperatures rise, the bees change how they fly to decrease the heat they generate from metabolism, which helps the insects avoid overheating and save precious water.

Australian birds that live on islands are among the species most at risk of extinction, a first-of-its-kind study has shown. Australia has over 750 native bird species. But many of them are facing an uncertain future.

Desert ants find their way during an early learning phase with the help of the Earth's magnetic field. The associated learning process leaves clear traces in their nervous system.

The properties of supramolecular polymers are dictated by the self-assembled state of the molecules. However, not much is known about the impact of morphologies on the properties of nano- and mesoscopic-scale polymeric assemblies. Recently, a research team demonstrated how terminus-free toroids and random coils derived from the same luminescent molecule show different photophysical properties. The team also presented a novel method for purifying the toroidal structure.

Chiral skyrmions are a special type of spin textures in magnetic materials with asymmetric exchange interactions. They can be treated as quasi-particles and carry integer topological charges. Scientists have recently studied the random walk-behaviors of chiral skyrmions by simulating their dynamics within a ferromagnetic layer surrounded by chiral flower-like obstacles. The simulations reveal that the system behaves like a topological sorting device, indicating its use in information processing and computing devices.

More time stranded on land means greater risk of starvation for polar bears, a new study indicates. During three summer weeks, 20 polar bears closely observed by scientists tried different strategies to maintain energy reserves, including resting, scavenging and foraging. Yet nearly all of them lost weight rapidly: on average around 1 kilogram, or 2.2 pounds, per day. Some have speculated that polar bears might adapt to the longer ice-free seasons due to climate warming by acting like their grizzly bear relatives and either rest or eat terrestrial food. The polar bears in this study tried versions of both strategies -- with little success.

Scientists examined hundreds of birds in museum collections and discovered a suite of feather characteristics that all flying birds have in common. These 'rules' provide clues as to how the dinosaur ancestors of modern birds first evolved the ability to fly, and which dinosaurs were capable of flight.

Analysis reveals imported earthworm species have colonized large swaths of North America, and represent a largely overlooked threat to native ecosystems. The researchers warn of the need to better understand and manage the invaders in our midst.

Scientists have discovered that nighttime air pollution -- coming primarily form car exhaust and power plant emissions -- is responsible for a major drop in nighttime pollinator activity. Nitrate radicals (NO3) in the air degrade the scent chemicals released by a common wildflower, drastically reducing the scent-based cues that its chief pollinators rely on to locate the flower. The findings show how nighttime pollution creates a chain of chemical reactions that degrades scent cues, leaving flowers undetectable by smell. The researchers also determined that pollution likely has worldwide impacts on pollination.

Scientists have discovered a tiny worm species that infects and kills insects. These worms, called nematodes, could control crop pests in warm, humid places where other beneficial nematodes are currently unable to thrive.

The ability to detect diseases at an early stage or even predict their onset would be of tremendous benefit to doctors and patients alike. A research team now develops intelligent, miniaturized biosensor devices and systems using nanomaterials to determine biomolecules and cells as well as biochemical reactions or processes as disease markers. The team's current publication describes the development of a portable, palm-sized test system that can simultaneously carry out up to thirty-two analyses of one sample.
