Fish generate movable pairs of vortices to propel them forward like body waves
Swimming in complex underwater environments, fish are unmatched when it comes to motion control and flexibility. For decades, researchers have been inspired to copy nature's most gifted swimmers to optimize underwater vehicle propulsion and maneuvera.....»»
"Paleo-robots" provide an experimental approach for understanding how fish started to walk on land
The transition from water to land is one of the most significant events in the history of life on Earth. Now, a team of roboticists, paleontologists and biologists is using robots to study how the ancestors of modern land animals transitioned from sw.....»»
Insect and spider biodiversity increases organic nutrient availability across ecosystems, large-scale study shows
Insects and spiders are important elements in the food webs of aquatic and terrestrial ecosystems. With declines in their biodiversity, the food supply for birds, fish, reptiles, amphibians and small mammals is not only becoming scarcer, but also poo.....»»
How bioacoustics and AI can help study animal populations in the forest and beneath the waves
Animal sounds combined with artificial intelligence (AI) can revolutionize biodiversity monitoring both on land and in aquatic settings according to researchers from the University of Copenhagen. By analyzing wildlife sounds, AI can now identify spec.....»»
Can we ever trust photos again, in an AI age? Apple and others working the problem
At a time when you can ask AI to modify an existing photo in almost any way you please, or even ask it to generate a completely artificial image, can we ever trust photos again? Apple is working to address the issue in two ways, and many of us are.....»»

Seismic anisotropy in the deep mantle could partly be derived from the deformation of hydrous phase D
Shear waves split into fast and slow waves when they travel through elastically anisotropic media, and the anisotropy of the seismic velocity is recorded by seismic stations. In the Earth's deep interior, this is usually interpreted as the effect of.....»»
Internet fiber optic cables successfully detect shock waves from a rockslide
On the night of 16 June 2023, about 1.2 million cubic meters of rock rumbled down into the valley near Brienz (GR). A team from the Swiss Federal Institute for Forest, Snow and Landscape Research WSL and ETH Zurich tracked the event using an unusual.....»»
NASA reveals prototype telescope for gravitational wave observatory
NASA has revealed the first look at a full-scale prototype for six telescopes that will enable, in the next decade, the space-based detection of gravitational waves—ripples in space-time caused by merging black holes and other cosmic sources......»»
Giant fish thought to be extinct is spotted in the Mekong River
A huge fish in the Mekong River thought to be extinct has been spotted three times in recent years......»»
A blueprint for mapping melting ice sheets: Open-source tool can help make radar systems at a fraction of the cost
Researchers in the Stanford Radio Glaciology lab use radio waves to understand rapidly changing ice sheets and their contributions to global sea-level rise. This technique has revealed groundwater beneath Greenland, the long-term impacts of extreme m.....»»
Photonic computing method uses electromagnetic waves to rapidly solve partial differential equations
In the fields of physics, mathematics, and engineering, partial differential equations (PDEs) are essential for modeling various phenomena, from heat diffusion to particle motion and wave propagation. While some PDEs can be solved analytically, many.....»»

There are no "damn dirty apes" among the three sci-fi movies on Hulu that you need to watch in October, but there is a giant monster, body horror, and aliens......»»
Ocean eddy currents funnel extreme heat and cold to the life-filled depths
On land, we're familiar with heat waves and cold snaps. But the deep sea also experiences prolonged periods of hot and cold......»»
Bizarre fish has sensory “legs” it uses for walking and tasting
Some sea robin species can use their legs to sense prey. Evolution has turned out bizarre and baffling creatures, such as walking fish. It only gets weirder from there. Some of th.....»»
Controlling sound waves with Klein tunneling improves acoustic signal filtration
In the context of sensory modalities, eyes work like tiny antennae, picking up light, electromagnetic waves traveling at blistering speeds. When humans look at the world, their eyes catch these waves and convert them into signals the brain reads as c.....»»
First results from the Axion Dark-Matter Birefringent Cavity experiment establish a new technique for axion search
Researchers at MIT recently published the first results of an experiment aimed at searching for axion dark matter by probing the axion-induced birefringence of electromagnetic waves. While these findings, published in Physical Review Letters, did not.....»»

Better ocean connectivity boosts reef fish populations, finds study
Research led by the University of Oxford has found that oceanographic connectivity (the movement and exchange of water between different parts of the ocean) is a key influence for fish abundance across the Western Indian Ocean (WIO). The findings are.....»»
