Bioengineers and chemists design fluorescent 3D-printed structures with potential medical applications
In a process as simple as stirring eggs and flour into pancakes, University of Oregon researchers have mixed fluorescent ring-shaped molecules into a novel 3D printing process. The result: intricate glowing structures that support the development of.....»»
Elucidating the mechanism of cell division during plant self-healing
When the stem of a plant is injured, the surrounding cells proliferate to repair and fuse the damaged tissue, eventually restoring function. This self-healing property is utilized in grafting techniques to propagate fruit and vegetable plants......»»
Scientists identify structural basis of stitched-together protein complexes that recycle most proteins in cells
Scientists at Sanford Burnham Prebys have developed a clearer picture of how crucial machinery in the human cell's recycling process for obsolete and misshapen proteins—known as proteasomes—are formed......»»
The unexpected role of magnetic microbes in deep-sea mining
Polymetallic nodules are potato-sized formations on the ocean floor that are rich in minerals such as nickel, cobalt, and manganese. Their concentration of rare, economically important minerals has made the nodules the focus of controversial deep-sea.....»»
Building better bone grafts: Nanofibrous scaffolds to activate two main collagen receptors in bone cells
Each year, about 2.2 million bone-grafting procedures are performed worldwide, the gold standard of care being autografting, which uses the patient's own bone for tooth implantation and to repair and reconstruct parts of the mouth, face and skull......»»
The 25 best YouTube videos for kids (September 2024)

In rare move from printing industry, HP actually has a decent idea
Opinion: Printers have gotten boring and untrustworthy. Enlarge (credit: Getty) The printer industry is in a rut. With the digitization of, well, nearly everything, people just don’t print like they used to. More mode.....»»
Genetic rescue for rare red foxes? Research uncovers options to restore Lassen red fox population
A rescue effort can take many forms—a life raft, a firehose, an airlift. For animals whose populations are in decline from inbreeding, genetics itself can be a lifesaver......»»
Scientists develop method to control timing of synthetic DNA droplet division
Many cellular functions in the human body are controlled by biological droplets called liquid-liquid phase separation (LLPS) droplets. These droplets, made of soft biological materials, exist inside living cells but are not enclosed by membranes like.....»»
Cretaceous fireflies reveal early evolution of insect bioluminescence
Bioluminescence, the ability of living organisms to emit light, is a fascinating phenomenon observed in various life forms, including deep-sea fish, glowing mushrooms, and fireflies. Fireflies have long captivated people with their enchanting light d.....»»
Key negotiator Norway sees "positive signals" ahead of plastic talks
In the single week that world leaders convened for high-level UN talks in New York, nearly 100,000 water bottles' worth of microplastics swirled through the city's air, posing known and still unknown risks to human health......»»
Improving industrial scale lactoferrin production with synthetic biological systems
Lactoferrin (LF), a multifunctional glycoprotein of the transferrin family, is naturally expressed in human and cow milk. The name "LF" is derived from its ability to bind to iron (ferrin, a suffix indicating iron-binding protein)......»»
Semimetal-induced covalency achieves high-efficiency electrocatalysis for platinum intermetallic compounds
Compared with other types of batteries, proton exchange membrane fuel cells have the advantages of high discharge power and no pollution, which is also an important carrier for hydrogen energy conversion and utilization. Platinum intermetallic compou.....»»
Tesla Full Self Driving requires human intervention every 13 miles

Why do people breach their bail? Research shows it"s not because they"re committing more crimes
In Australia and most countries, everyone is innocent until proven guilty. Because of this, keeping someone in detention before trial comes with serious legal, practical and human-rights consequences, not just for the person accused but also for thei.....»»
Murine study suggests cosmic radiation in outer space may affect long-term cognition
During missions into outer space, galactic cosmic radiation (GCR) will penetrate current spacecraft shielding and thus pose a significant risk to human health......»»
ALICE probes the strong interaction three-body problem with new measurements of hadron–deuteron correlations
In an article recently published in Physical Review X, the ALICE collaboration presented its studies of correlations in the kaon–deuteron and proton–deuteron systems, opening the door to precise studies of the forces in three-body nuclear systems.....»»
Can the "hard steps" in the evolutionary history of human intelligence be recast with geological thresholds?
What took so long for humans to appear on Earth? The Earth is 4.6 billion years old, and life began about 4 billion years ago, yet humans—the only intelligent, technological species we know of in the universe—have existed only for the last 200,0.....»»
