Induced-fit adsorbent for acetylene
We often say that a substrate fits into its enzyme like a key in a lock, but this metaphor is imperfect. Substrate binding can also change the lock (the structure of the enzyme) to induce a perfect fit. In the journal Angewandte Chemie, an internatio.....»»
Orbitally induced strong monsoons facilitated early human dispersal to East Asia, finds study
In a study published in Proceedings of the National Academy of Sciences, researchers have shown that orbitally induced strengthening of the Asian summer monsoon played a key role in the dispersal of Homo sapiens from Africa to East Asia during the la.....»»
Hurricane waves hitting Americas grow 20% per decade: Study
The U.S., Mexico and countries in the Caribbean are being battered by hurricane-induced ocean waves that have grown in areal size by 80% over the past 40 years, a new study has found......»»
Permian marine mass extinction linked to volcanism-induced anoxia
Mass extinctions are rapid global decreases in Earth's biodiversity, with five key events identified over the planet's history, arguably the most famous of which occurred ~66 million years ago during the Cretaceous, which brought the rein of dinosaur.....»»
Global warming intensifies typhoon-induced extreme precipitation over East Asia
Last year, Typhoon Hinnamnor, which caused 36 fatalities, gained notoriety as the first super typhoon that developed at a high latitude as 25°N since Korea Meteorological Administration records began. This year in Osong, Chungcheongbuk-do, an unanti.....»»
Novel molecular ionization dissociation pathway induced by Interatomic Coulombic Decay
A research group led by Prof. Ma Xinwen at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) has observed a novel molecular ionization dissociation pathway triggered by Interatomic Coulombic Decay (ICD). The study, publis.....»»
Researchers reveal anthropogenically-induced atmospheric lead cycle in low-latitude Asia
In recent decades, environmental lead (Pb) pollution has posed a significant threat to public health and ecological systems due to its harmful and irreversible effects. It has also been proposed that the distinct Pb pollution signals in geological ar.....»»
Developing a futuristic elastomer with ultrahigh strain-induced crystallization
Strain-induced crystallization can strengthen, toughen, and facilitate an elastocaloric effect in elastomers. The resulting crystallinity can be induced by mechanical stretching in common elastomers that are typically below 20%, with a stretchability.....»»
Was the Peace River earthquake induced or natural? New study tests frameworks to answer the question
Using questionnaires created to determine whether a particular earthquake is natural or induced by human activity, a panel of experts concluded that the November 2022 magnitude 5.2 Peace River earthquake sequence in Alberta, Canada was likely induced.....»»
Field-induced superconductivity in quantum materials
Field-induced superconductivity occurs when an applied magnetic field increases or induces superconductivity. In a new report published in Science Advances, Joshua J. Sanchez and a team of scientists applied stress as a switch between a field tunable.....»»
Farmers and ranchers in the Southwestern US face challenges due to human-induced atmospheric warming
The American Southwest has always been a dry place—cue romantic visions of hot, rugged, sun-bleached, seemingly infinite landscapes and star-filled night skies. And yet, the plants, animals and people of the Four Corners region (Utah, Colorado, New.....»»
A mechanism of pressure-induced glass phase transition leading to advanced phase-change memories
When temperature or pressure is applied to a material, its state changes from liquid to solid or remains solid but exhibits structural changes. This change is called a phase transition or change......»»
Team reviews phosphine ligand-induced structural transformation of metal nanoclusters
A team of researchers has reviewed a unique method for reforming the structures of ultra-small nanomaterials. These nanomaterials, called metal nanoclusters, bridge the gap between the metal atom and the bulk metal, making them highly useful in both.....»»
SPAGINS: A novel approach to predicting nuclear fragmentation in gamma-induced spallation
In a study published in Nuclear Science and Techniques, researchers from Henan Normal University report a significant advancement in nuclear physics. The study showcases the effectiveness of the SPAGINS model, a novel approach to accurately predictin.....»»
How mountains affect El Niño-induced winter precipitation
A consideration of how mountains influence El Niño and La Niña-induced precipitation change in western North America may be the ticket to more informed water conservation planning along the Colorado River, new research suggests......»»
"Silent devastation" of drought set to increase globally under climate change, says UN report
Recent drought-related data compiled by the UN point to "an unprecedented emergency on a planetary scale, where the massive impacts of human-induced droughts are only starting to unfold.".....»»
Laser-induced hydrothermal growth for electrocatalytic applications
In the new study published in the journal International Journal of Extreme Manufacturing on 1 November 2023, researchers from the UK and China reported a novel technique based on a laser-induced hydrothermal reaction (LIHR) mechanism for the growth o.....»»
Green growth or degrowth: What is the right way to tackle climate change?
Nearly all the world's governments and vast numbers of its people are convinced that addressing human-induced climate change is essential if healthy societies are to survive. The two solutions most often proposed go by various names but are widely kn.....»»
Crop yield prediction: New model uses sun-induced chlorophyll fluorescence for enhanced photosynthetic trait estimation
Crops use carbon dioxide (CO2) through photosynthesis to create organic matter, with enhanced photosynthetic rates crucial for meeting global food demands. While crop phenomics has focused on structural traits, it's the functional traits like maximum.....»»
Meet “Amaterasu”: Astronomers detect highest energy cosmic ray since 1991
