- A technique to cool the planet, in which particles are added to the atmosphere to reflect sunlight, would not require developing special aircraft but could be achieved using existing large planes, according to a new modeling study led by UCL (University College London) researchers.
- "Get off my lawn!" Funny as a meme but maybe scary in real life, this short sentence is synonymous with an elderly man shouting at kids whose bikes have gotten too close to a well-manicured front yard. But it could just as well represent a female bird, aggressively chasing whatever intruder gets too close to her nest.
- An international team of scientists led by a Rutgers University–New Brunswick astrophysicist has discovered a potentially star-forming cloud that is one of the largest single structures in the sky and among the closest to the sun and Earth ever to be detected.
- New research involving Rutgers professors has revealed that expected, extreme changes in India's summer monsoon could drastically hamper the Bay of Bengal's ability to support a crucial element of the region's food supply: marine life.
- A new study, appearing in Nature Genetics and led by researchers at King Abdullah University of Science and Technology (KAUST, Saudi Arabia) and Wageningen University & Research (the Netherlands), provides new insights into rice evolution, showing how the DNA of this valuable crop has changed across species. The findings are expected to not only help with improving rice yields but also with the introduction of rice into regions where rice production is currently untenable.
- Exceptional points (EPs) are unique types of energy-level degeneracies that occur in non-Hermitian systems. Since their existence was first proposed more than a century ago, physicists have only been able to experimentally observe two types of EPs, both of which were found to give rise to exotic phases of matter in various materials, including Dirac and Weyl semimetals.
- Many modern industrial processes depend on complex chemistry. Take fertilizer production, for example: to make it, companies must first produce ammonia, a key ingredient.
- Oregon Health & Science University, in collaboration with Oregon State University, has discovered the structural organization and protein components of a lipid-transfer complex known as LPD-3. Findings show that LPD-3 contains an internal tunnel lined with lipid molecules, suggesting a possible mechanism for large-scale lipid movement between cellular membranes.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- A new study led by Jochen Knies from the iC3 Polar Research Hub has found worrying signs that climate change may be undermining the capacity of Arctic fjords to serve as effective carbon sinks. The findings suggest that the capacity of polar oceans to remove carbon from the atmosphere may be reduced as the world continues to heat up.
- Found in everything from kitchen appliances to sustainable energy infrastructure, stainless steels are used extensively due to their excellent corrosion (rusting) resistance. They're an important material in many industries, including manufacturing, transportation, oil and gas, nuclear power and chemical processing.
- In every scientific discovery in the movies, a scientist observes something unexpected, scratches the side of his or her forehead and says "hmmmmm." In just such a moment in real life, scientists from Canada observed unexpected flashes of curved green light from a red light-emitting polymer above its surface. The flashes were reminiscent of the colored arcs that auroras take above Earth's poles, providing a clue as to their provenance.
- University of Central Florida (UCF) scientists and their collaborators discovered new insights into the formation of distant icy objects in space beyond Neptune, offering a deeper understanding of our solar system's formation and growth.
- The hydrogen evolution reaction (HER) is a remarkable process that can create clean hydrogen fuel—a potential part of a solution to our climate change crisis. The problem lies in scaling up this reaction from a lab experiment to large-scale commercial production, while keeping costs down.
