Enhancing hurricane forecasts: Simulations reveal reducing estimates of atmospheric friction improves storm predictions

Enhancing hurricane forecasts: Simulations reveal reducing estimates of atmospheric friction improves storm predictions

Hurricanes and other extreme weather events are expensive in lives and money. From 1980 to 2023, weather and climate disasters caused about $2.6 trillion in damages in the U.S., according to NOAA estimates. In 2022 alone, the U.S. experienced 18 disasters individually costing $1 billion or more. Worse, U.S. hurricanes from 2000 to 2021 took almost 2,000 lives. As climate change continues to intensify these storms, accurate forecasting becomes ever more crucial.

From branches to loops: The physics of transport networks in nature

From branches to loops: The physics of transport networks in nature

An international team of researchers described how loops, crucial for the stability of such networks, occur in transport networks found in nature. The researchers observed that when one branch of the network reaches the system's boundary, the interactions between the branches change drastically. Previously repelling branches begin to attract each other, leading to the sudden formation of loops.

Scientists use drones to track white sharks along California beaches

Scientists use drones to track white sharks along California beaches

The forecast at the beach today is cloudy, with a chance of sharks. At least, that's the forecast that researchers at UC Santa Barbara would like to be able to provide. They're leading a project to predict when and where great white sharks show up near a beach.

Bioengineers and chemists design fluorescent 3D-printed structures with potential medical applications

Bioengineers and chemists design fluorescent 3D-printed structures with potential medical applications

In a process as simple as stirring eggs and flour into pancakes, University of Oregon researchers have mixed fluorescent ring-shaped molecules into a novel 3D printing process. The result: intricate glowing structures that support the development of new kinds of biomedical implants.

Research team succeeds in ultra-fast switching of tiny light sources

Research team succeeds in ultra-fast switching of tiny light sources

Extremely thin materials consisting of just a few atomic layers promise applications for electronics and quantum technologies. An international team led by TU Dresden has now made remarkable progress with an experiment conducted at Helmholtz-Zentrum Dresden-Rossendorf (HZDR): The experts were able to induce an extremely fast switching process between electrically neutral and charged luminescent particles in an ultra-thin, effectively two-dimensional material.

Forest loss forces langur species to interbreed, study shows

Forest loss forces langur species to interbreed, study shows

Research shows a threatening development for two endangered primate species in Bangladesh: Phayre's langurs (Trachypithecus phayrei) and capped langurs (Trachypithecus pileatus). In mixed groups of these two species, hybrids have been found and genetically confirmed. If hybridization continues, it could mean the extinction of one or both species.

Ryugu samples call into question previous ideas about the formation of carbon-rich asteroids

Ryugu samples call into question previous ideas about the formation of carbon-rich asteroids

Asteroid Ryugu possibly did not travel as far from its place of origin to its current near-Earth orbit as previously assumed. New research published in the journal Science Advances suggests that Ryugu was formed near Jupiter.
