Aryl radical formation by aryl halide bond cleavage by a N-heterocyclic carbene catalyst
Aryl halides with a benzene ring directly bonded to a halogen atom are readily available and chemically stable, so they are used as a source of benzene rings in organic synthesis. For example, a chemical reaction that generates a highly reactive aryl.....»»
Music education, support networks, and continuity are key factors regulating adolescents" arts participation, says study
How do young people find their way to music-making? Researchers Anna Kuoppamäki from the University of the Arts Helsinki and Fanny Vilmilä from the Finnish Youth Research Network identified factors that had a significant impact on the formation of.....»»
Advanced artificial photosynthesis catalyst uses CO₂ more efficiently to create biodegradable plastics
Amid growing global concern over climate change and plastic pollution, researchers at Osaka Metropolitan University are making great strides in the sustainable production of fumaric acid—a component of biodegradable plastics such as polybutylene su.....»»
New insights in the regulation of genetic information exchange
Within every cell in our body, our DNA is tightly bundled with proteins to form structures known as chromosomes. The commonly known shape of a chromosome relates to an X-shaped appearance in many organisms. The formation of the X-shaped chromosome re.....»»

Which came first: Black holes or galaxies?
Black holes not only existed at the dawn of time, they birthed new stars and supercharged galaxy formation, a new analysis of James Webb Space Telescope data suggests......»»
Hubble spies baby stars being born amid chaos of interacting galaxies
Amid swirling gas and dust pulled by gravitational forces of interacting galaxies, there can be bursts of star formation, creating new generations of stars......»»
Results from South Pole Telescope"s new camera emerge
For more than five years, scientists at the South Pole Telescope in Antarctica have been observing the sky with an upgraded camera. The extended gaze toward the cosmos is picking up remnant light from the universe's early formation. Now researchers h.....»»
Understanding jasmonic acid: A switch that activates autophagy in Arabidopsis petals
Organogenesis, an important aspect of flowering, helps reveal key processes of plant development such as the formation of floral organs, attainment of reproductive capability, and abscission leading to seed and fruit development......»»
Secondary eyewall formation in upper- and lower-layer vertical wind shear simulated in idealized tropical cyclones
About 80% of intense tropical cyclones (TCs) possess concentric eyewalls—namely, the primary and secondary eyewalls. The intensity of the TC can vary considerably during secondary eyewall formation (SEF) and eyewall replacement, posing a great chal.....»»
Study challenges classical view of the Antarctic Circumpolar Current origin and warns of its vulnerability
The Circumpolar Current works as a regulator of the planet's climate. Its origins were thought to have caused the formation of the permanent ice in Antarctica about 34 million years ago. Now, a study led by the University of Barcelona, the Instituto.....»»
Researchers develop biomimetic-photo-coupled catalysis for H₂O₂ production
A research group led by Prof. Wan Yinhua from the Institute of Process Engineering of the Chinese Academy of Sciences has developed a catalyst with dual photocatalytic and biomimetic catalytic activity for the production of hydrogen peroxide (H2O2)......»»
How did life get started on Earth? Atmospheric haze might have been the key
A recent study accepted to The Planetary Science Journal and currently posted to the arXiv preprint server investigates how the organic hazes that existed on Earth between the planet's initial formation and 500 million years afterwards, also known a.....»»
Researchers uncover source rocks of the first real continents
Geoscientists have uncovered a missing link in the enigmatic story of how the continents developed—a revised origin story that doesn't require the start of plate tectonics or any external factor to explain their formation. Instead, the findings pub.....»»
Green methanol for the circular economy: Researchers develop new catalyst
Researchers hope to produce the raw material methanol at the edge of a field or on the farm using renewable energy. In addition to wind or sun, water and CO2 would be needed to produce the raw materials for the green methanol process: carbon monoxide.....»»
The moon is shrinking, causing moonquakes at the lunar south pole
New research from NASA suggests that the shrinking of the moon over time is causing moonquakes and the formation of faults near its south pole......»»
A breath of fresh air in plasmonic catalysis: Black gold and solar light"s renaissance
Prof. Polshettiwar's group at Tata Institute of Fundamental Research (TIFR), Mumbai has developed a novel "plasmonic reduction catalyst stable in air," defying the common instability of reduction catalysts in the presence of air. The catalyst merges.....»»
ALMA observations: Researchers reveal dynamic view of massive protocluster evolution
A team of researchers has jointly launched the ALMA Survey of Star formation and Evolution of Massive Protoclusters with Blue-profiles (ASSEMBLE) project. They revealed the growth in mass and density of cluster members, along with increasing proximit.....»»
Unveiling and decoding the regulatory mechanisms of secondary cell wall formation
Wood quality is primarily determined by the properties of its secondary cell wall (SCW). Gaining insight into the molecular processes governing SCW development is crucial for the genetic enhancement of wood quality. Although it's established that a m.....»»
