Jayawardhana The James Webb Space Telescope has spotted six likely rogue worlds—objects with planetlike masses but untethered from any star’s gravity—including the lightest ever identified with a dusty disk around it. … Read more
A cemetery on Majuro Atoll is flooded by high tides and ocean surges in the low-lying Marshall Islands, which rises barely a metre above sea level. United Nations Secretary-General Antonio Guterres sent out a global climate “SOS” at a Pacific islands summit on Tuesday, unveiling research that shows the region’s seas rising much more swiftly … Read more
N6-methyladenine levels in the C. elegans mitochondrial genome gradually increase with age. (A) The 6mA progressively accumulates at different mtDNA sites (mito 3 and mito 4) during aging. (A’) Quantification of the relative mtDNA 6mA levels at different adult stages. Bars indicate ±S.D.; each comparison reveals ***: p International Journal of Molecular Sciences (2023).

Response of microtubules to the essential oil of M. x piperita in Arabidopsis. Credit: Horticulture Research A recent study reveals the natural compound (-)-carvone in spearmint as a potent and sustainable alternative to chemical herbicides. This research demonstrates how (-)-carvone targets and degrades microtubules in weeds, inducing cell death and inhibiting growth without harming the … Read more
Both versions of the Solar Array Sun Shield for NASA’s Nancy Grace Roman Space Telescope appear in this photo, taken in the largest clean room at NASA’s Goddard Space Flight Center. The flight version lies flat in the foreground, while the qualification assembly stands upright in the background. The flight panels will shade the mission’s … Read more
