Pigs can regrow their adult teeth. What if humans could, too?
25 April 2025 @ 9:05 pm
When children lose their baby teeth, there is an adult set already growing beneath the gums, ready to emerge. But if we lose our permanent teeth, there aren't any more waiting in the wings. Right now, the options for replacing these lost teeth are either dentures or titanium implants, neither of which provide the same function and feedback as a real, living tooth.
Ultrafast optical technique reveals how electrical double layers form in liquids
25 April 2025 @ 9:05 pm
Charged surfaces in contact with liquids—such as biological cell walls or battery electrodes—attract oppositely charged ions from the liquid. This creates two distinct charged regions: the surface itself and a counter-charged region in the liquid: the so-called electrical double layer. While pivotal to energy storage devices, the speed of its formation has remained elusive.
Multi-spacecraft radio observations trace the heliospheric magnetic field
25 April 2025 @ 9:04 pm
Solar flares accelerate energetic electrons that escape into interplanetary space, guided by the Parker spiral magnetic field, and are responsible for the generation of the interplanetary Type III solar radio bursts. With multiple spacecraft now in orbit around the sun, we are in a unique position of observing the propagation of radio emission through the heliosphere from multiple vantage points.
Magnetic confinement advance promises 100 times more fusion power at half the cost
25 April 2025 @ 9:03 pm
A team of fusion researchers at TAE Technologies, Inc., in the U.S., working with colleagues from the University of California, has developed a new type of fusion technology that the company claims produces 100 times the power of other designs while costing just half as much to run. Their study is published in the journal Nature Communications.
Gapless genome sequence reveals hybrid origins of Hong Kong's iconic orchid tree
25 April 2025 @ 5:18 pm
April 25 is International DNA Day, and it marks the completion of a decade-long project to sequence the DNA of Hong Kong's floral emblem, the Hong Kong Orchid Tree Bauhinia x blakeana Dunn.
How bacteria and textile fibers can heal bones
25 April 2025 @ 4:49 pm
Have you ever wondered if there is a way to heal bones without having to take bone from another part of the body? A new doctoral thesis from the University of Borås, Sweden, now presents exciting advancements in this area. It involves using bacteria to produce fibers that can help heal bones.
Circinus West: A dark nebula harboring a nest of newly formed stars
25 April 2025 @ 4:41 pm
A celestial shadow known as the Circinus West molecular cloud creeps across this image captured from Chile with the 570-megapixel Department of Energy–fabricated Dark Energy Camera—one of the most powerful digital cameras in the world. Within this stellar nursery's opaque boundaries, infant stars ignite within cold, dense gas and dust, while outflows hurtle leftover material into space.
Scientists develop novel strategy to enhance water oxidation catalysis
25 April 2025 @ 4:25 pm
A research team has developed a highly stable and efficient water oxidation catalyst, marking a major advancement in the field of green hydrogen production via water splitting technology.
Up to 42% of insect behavioral experiments not reproducible across laboratories
25 April 2025 @ 4:14 pm
If an experiment is repeated under similar conditions, the results should be the same. In reality, the situation is often different—scientists speak of a "reproducibility crisis," which affects different disciplines.
Observatory develops high-efficiency muon detection system with novel plastic scintillator design
25 April 2025 @ 4:01 pm
Researchers from Sun Yat-sen University (SYSU) and the Institute of High Energy Physics (IHEP) have developed a novel top veto tracker system for the Taishan Antineutrino Observatory (TAO) experiment.
