A team of Israeli scientists at the Hebrew University of Jerusalem has developed a novel method to significantly lower the production costs of cultivated meat. The new study demonstrates that preloading plant-derived cellulose scaffolds with growth factors supports the cost-efficient proliferation and differentiation of bovine stem cells. By binding these vital proteins directly to an anisotropic, directionally frozen framework instead of dispersing them in liquid media, this method achieves high-quality tissue development using up to 10 times fewer expensive factors. Upon multi-week cultivation and subsequent pan-frying, the cell-bound constructs show partially similar mechanical and visual responses to traditional sirloin cuts.

There is an 80% chance of the warming El Niño phenomenon developing between June and August, increasing the risk of extreme weather events, the World Meteorological Organization said Tuesday.

A major study suggests that some of the groundwork for brain development may be shaped before birth through a surprising partnership between a baby’s genes and gut microbes. Researchers found that epigenetic changes present at birth can influence how the gut microbiome develops during the first year of life, and certain combinations were linked to early signs of autism and ADHD by age three.

A massive global analysis found that nitrogen pollution can either speed up or dramatically slow the natural "breathing" of forest soils, depending on the ecosystem's condition. The results reveal hidden tipping points that could affect how forests store carbon and cope with climate change.

Turkey vultures (Cathartes aura) may not be beautiful, but they are certainly adaptable. A new study published in the Journal of Raptor Research, titled "Turkey Vulture Aggregations at a Water Barrier Provide Evidence of Later Migration and Increasing Population Size Over 25 Years," suggests that turkey vultures in western North America are increasing in number and delaying their migration departure date.

Glasses are non-crystalline but solid states of matter in which molecules and atoms are not arranged into a regular crystal lattice, but rather in a disordered pattern. Glassy materials are widely used in various settings, for instance, in the synthesis of pharmaceuticals and the development of electronics or optical devices.

Astronomers have finally cracked the mystery behind a strange class of repeating cosmic signals that has baffled scientists for years. Using Australia’s ASKAP radio telescope, researchers traced the bursts to a rare stellar duo in which a dense white dwarf is relentlessly siphoning material from a nearby red dwarf companion. As the stolen matter spirals inward, the system unleashes powerful radio waves and X-rays every 1.4 hours.
