Numerical weather prediction (NWP) systems use large amounts of observational data gathered daily using satellite-based and ground-based instruments to make forecasts, but maintaining them is costly and time-consuming. Now, researchers from Japan have tested the feasibility of using drones equipped with meteorological sensors to complement NWP systems. The results highlight the potential of using commercial drones in densely populated urban areas and sparse meteorological observation areas, to make NWP data collection more convenient and inexpensive.  

Deeply hidden in Earth’s mantle there are two huge ‘islands’ with the size of a continent. New research from Utrecht University shows that these regions are not only hotter than the surrounding graveyard of cold sunken tectonic plates, but also that they must be ancient: at least half a billion years old, perhaps even older. These observations contradict the idea of a well-mixed and fast flowing Earth’s mantle, a theory that is becoming more and more questioned. “There is less flow in Earth’s mantle than is commonly thought.”

In a paper published in National Science Review, a bottom-up isoprene emission inventory, including both biogenic and combustion sources, was developed and used to model the contributions of isoprene to secondary organic aerosol formation in China. The results show that emissions of isoprene from combustion sources contributed substantially to ambient secondary organic aerosol, particularly during winter.

Around 45 million years ago, a 4.6 feet-tall (1.40 metres) flightless bird called Diatryma roamed the Geiseltal region in southern Saxony-Anhalt. An international team of researchers led by the Martin Luther University Halle-Wittenberg (MLU) and the Senckenberg Research Institute and Natural History Museum in Frankfurt report on the bird's fully preserved skull in the scientific journal "Palaeontologia Electronica". The fossil was unearthed in the 1950s in a former lignite mining area in the Geiseltal in Germany. It was initially misclassified and thus led a shadowy existence until its rediscovery. The only other place that a similar skull fossil has been found is the USA.

The research by University of Sydney marine scientists highlights the complex interplay between heat stress, disease onset and coral mortality. It found that 66 percent of the colonies were bleached by February 2024 and 80 per cent by April. By July, 44 percent of the bleached colonies had died, with some coral genera, such as Acropora, experiencing a staggering 95 percent mortality rate.

Archaeologists have uncovered a rare Tetrarchic boundary stone at the site of Abel Beth Maacah in northern Israel. Originally marking land borders under Roman Emperor Diocletian’s tax reforms, the stone provides insight into ancient land ownership, local settlement patterns, and imperial administrative practices. The discovery also introduces two previously unknown place names, expanding our understanding of the region’s historical geography and socio-economic landscape.
