Credit: Science Bulletin (2024). DOI: 10.1016/j.scib.2024.07.041 Chloroplast, which is a double-membrane-bounded organelle, is the main site for CO2 fixation via photosynthesis in green plants. The double-membrane configuration can regulate the transport of substances into and out of the chloroplasts with the aid of functional units like lipid bilayer and transmembrane proteins. Inspired by the ingenious … Read more

Distinct roles of H3K27me3 and H3K36me3 in vernalization response, maintenance, and resetting in winter wheat. Credit: Science China Press Vernalization is the phenomenon whereby plants require prolonged exposure to low temperatures to flower. This ensures that overwintering plants undergo reproductive growth under suitable light and temperature conditions, thereby securing yield. Wheat is primarily classified into … Read more

Non-Abelian and Abelian exchange statistics. (a) Non-Abelian exchange statistics of MZMs, the final state differs if the order of two pair-wise exchange operations is interchanged. (b) Abelian exchange statistics of ordinary particles such as electrons and photons, swapping the order of the exchange operations will not affect the final state. U23U12 means exchange particles 1 … Read more

Structure of Thermonuclease from Staphylococcus aureus predicted by AlphaFold2. Change in stability upon mutation, ∆∆G (positive values are destabilizing), is plotted as a function of effective strain measured at the mutated site, and in a spherical region near the mutated site, for 491 mutants. The black line shows the median. Statistical correlations are shown for … Read more

They’re temporarily introducing chemicals and microscopic organisms into their local waterways, according to new research from Johns Hopkins University. The research, published in ACS ES&T Water, is the first holistic assessment of … Read more

The knot-like i-motif structure protruding from DNA’s double helix has been mapped in 50,000 locations in the human genome, concentrated in key functional areas including regions that control gene activity. Credit: Garvan Institute Researchers have mapped 50,000 of DNA’s mysterious “knots” in the human genome. The innovative study of DNA’s hidden structures may open up … Read more

Thousands were forced to flee their homes as the massive blaze raged out of control for three days towards the capital earlier this month. With the smell still lingering in its suburbs after Greece’s worst wildfire this year, floods and pollution now threaten Athens, experts say. Thousands were forced to flee their homes as the … Read more

Manila residents walk amid debris in the aftermath of Typhoon Gaemi, which led to at least 40 deaths in the country. Climate change turbocharged the winds and rain of Typhoon Gaemi, which killed dozens of people across the Philippines, Taiwan and China earlier this year, a group of scientists said Thursday. Gaemi skirted the Philippines … Read more

A juvenile tiger shark. Credit: Albert Kok/Wikipedia A new study showing how a prehistoric sea cow was preyed upon by not one, but two different carnivores—a crocodilian and a shark—is revealing clues into both the predation tactics of ancient creatures and the wider food chain millions of years ago. Published in the Journal of Vertebrate … Read more

(a) Survey respondents’ preferences for vehicle type (e.g., small sedan, pickup truck) when considering the purchase of PEVs; (b) preferences for new vs. used vehicle market, regardless of vehicle technology; and (c) preferences for new vs. used vehicle market for PEVs, differentiated by annual income. For each income group, the total sums to 100%. Credit: … Read more
