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.....»»
A novel machine learning model for molecular simulation under an external field
Prof. Jiang Bin's research team at the University of Science and Technology of China (USTC) have developed a universal field-induced recursively embedded atom neural network (FIREANN) model, which can accurately simulate system-field interactions wit.....»»
Geese "keep calm and carry on" after deaths in the flock, says study
Canada geese strengthen existing friendships and forge a few new connections after losing close associates from their flock, new research shows. The paper, published in the Journal of Applied Ecology, is titled "Culling-induced perturbation of social.....»»
Mac sales are resuming normal growth, after pandemic and Apple Silicon bumps
Understanding what’s happening to Mac sales over the past few years is a tricky business, due to the convergence of three different factors: pandemic-induced demand, COVID-related supply disruptions, and early upgrades driven by the switch to Apple.....»»
Global warming–induced sea level changes could increase earthquake risk
Earthquakes often occur along plate boundaries, when sudden movements of the "stuck" plates release elastic strain energy, sending out seismic waves that result in the ground shaking familiar to many worldwide. More rarely, earthquakes occur within p.....»»
Research explores molecular basis of ventilator-induced diaphragm weakness
A study, published in PNAS Nexus, presents evidence that mitochondrial fragmentation is a proximal mechanism underlying ventilator-induced diaphragm dysfunction (VIDD)—and identifies a possible therapeutic to limit diaphragm atrophy during a stay.....»»
Gate induced room-temperature magnetic phase transition realized in van der Waals ferromagnet nanoflakes
By intercalating protons into van der Waals ferromagnet Cr1.2Te2 nanoflakes, a group of researchers successfully induced a room-temperature magnetic phase transition from ferromagnetism to antiferromagnetism......»»
Researchers report effect of hypoxia on periosteal stem cells
A new study has shown that the interaction of miR-584-5p and RUNX2 could mediate PSC osteogenic differentiation induced by hypoxia. The work is published in the World Journal of Stem Cells......»»
Examining how a sustainable future is based on a learning society
Escalating planetary crises, including climate change, the depletion of natural resources and the human-induced sixth mass extinction, pose increasing demands on pursuing a good life. As the planet is reaching its limits, old perceptions of well-bein.....»»
Experiments show molecules, not substrates, are mostly responsible for chirality-induced spin selectivity
A team of chemists at Northwestern University, working with a pair of colleagues from Università di Parma, reports that the chirality-induced spin selectivity (CISS) effect is caused by the molecules involved, not a substrate, when quantum spin is t.....»»
Multifactorial stress in citrus: Divergent responses of Carrizo and Cleopatra to triple threat environmental challenges
Climate change, alongside human-induced adverse factors, threatens agricultural production and food security by causing stressful situations for plants, such as increased temperatures, extreme weather events, pest outbreaks, diseases, and pollution......»»
Nitrogen enrichment delays the emergence of an aridity-induced threshold for plant biomass
Crossing certain aridity thresholds in global drylands can lead to abrupt decays of ecosystem attributes such as plant productivity, potentially causing land degradation and desertification. It is largely unknown, however, whether these thresholds ca.....»»
DNA aptamer finds novel application in regulating cell differentiation
Generating specific cell lineages from induced pluripotent stem cells and embryonic stem cells is the holy grail of regenerative medicine. Guiding iPSCs toward a target cell line has garnered much attention, but the process remains challenging......»»
Novel sustainable coupling technology proposed for carbon-to-acetylene process
The carbide-based carbon-to-acetylene (C2H2) process is a simple pathway to convert various sources of carbon into acetylene and carbon monoxide directly. However, the current industrial process based on calcium carbide (CaC2) is restricted by high e.....»»
Researchers develop nonlinear optical crystals by unusual cationic substitution strategy
An ideal infrared (IR) nonlinear optical (NLO) crystal must have the advantages of a wide transmittance range, impressive laser-induced damage threshold (LIDT), sufficient birefringence index, bulk single-crystal form, and physicochemical stability......»»
Super-efficient laser light-induced detection of cancer cell-derived nanoparticles achieved
Can particles as minuscule as viruses be detected accurately within a mere five minutes? Osaka Metropolitan University scientists say yes, with their innovative method for ultrafast and ultrasensitive quantitative measurement of biological nanopartic.....»»
Fabricating fused silica optics with a high laser-induced damage threshold
Residual processing defects significantly reduce fused silica optics' laser-induced damage threshold (LIDT), which seriously limits their performance and lifetime in high-energy laser applications. Extensive research has been conducted to eliminate a.....»»
Researchers develop novel multi-sensor data fusion methods for rapid and accurate compound fertilizer quality detection
In a study published in Talanta, a research team led by Prof. Wu Yuejin from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a data fusion strategy based on near-infrared spectroscopy (NIRS) and laser-induced.....»»
Memory-induced Magnus effect: Looking at the unexpected curveball in miniature
Whether you are familiar with the term "Magnus effect" or not, you have certainly seen it in action. It is when a spinning ball—for instance in football, cricket or baseball—bends away from its expected trajectory, often to the surprise of the op.....»»
Shading the Great Barrier Reef from the sun might slow bleaching-induced coral decline
Over the past two decades, coral reefs have declined at unprecedented rates. This is in part because of extreme weather events, which cause wide-spread coral bleaching, a process during which corals lose their color because of stressors, including ch.....»»
Human emissions shown to drive changes in North Atlantic ocean temperatures, West African rainfall and hurricanes
A new climate study led by scientists at the University Miami Rosenstiel School of Marine, Atmospheric, and Earth Science found that temperature fluctuations in the tropical Atlantic Ocean temperature are largely driven by human-induced aerosol emiss.....»»
