Fights: fishes vs. birds

Why Evolution is True Feed - Tue, 02/04/2025 - 10:50am

I am not particularly keen on seeing fish catching birds—or, indeed, seeing any animals eaten by others—but of cours that’s the way Nature works.  So here we see a 6½-minute BBC Earth video showing  terns in the Indian Ocean becoming possible meals for giant trevally (Caranx ignobilis).  It’s natural selection, Jake! But I’m still glad that the bird in the last segment escapes.

Pushing the boundaries of flat optics

Matter and energy from Science Daily Feed - Tue, 02/04/2025 - 10:25am
A research team has developed a novel multidimensional sampling theory to overcome the limitations of flat optics. The study not only identifies the constraints of conventional sampling theories in metasurface design but also presents an innovative anti-aliasing strategy that significantly enhances optical performance.

Why do plants transport energy so efficiently and quickly?

Matter and energy from Science Daily Feed - Tue, 02/04/2025 - 10:25am
Photosynthesis -- mainly carried out by plants -- is based on a remarkably efficient energy conversion process. To generate chemical energy, sunlight must first be captured and transported further. This happens practically loss-free and extremely quickly. A new study shows that quantum mechanical effects play a key role in this process.

Flipping the script: Inverse-design as game-changer in physics

Matter and energy from Science Daily Feed - Tue, 02/04/2025 - 10:24am
Physicists have achieved a breakthrough in data processing by employing an 'inverse-design' approach. This method allows algorithms to configure a system based on desired functions, bypassing manual design and complex simulations. The result is a smart 'universal' device that uses spin waves ('magnons') to perform multiple data processing tasks with exceptional energy efficiency. This innovation marks a transformative advance in unconventional computing, with significant potential for next-generation telecommunications, computing, and neuromorphic systems.

Wobbling stars reveal hidden companions in Gaia data

Space and time from Science Daily Feed - Tue, 02/04/2025 - 10:21am
Using data from the European Space Agency's Gaia mission, scientists have found a huge exoplanet and a brown dwarf. This is the first time a planet has been uniquely discovered by Gaia's ability to sense the gravitational tug or 'wobble' the planet induces on a star. Both the planet and brown dwarf are orbiting low-mass stars, a scenario thought to be extremely rare.

Nanomaterials are emerging as a powerful tool for coastal oil spill cleanup

Matter and energy from Science Daily Feed - Tue, 02/04/2025 - 10:21am
Advances in nanotechnology may provide solutions to oil spill cleanups in coastal regions that are more effective, safer and work much faster than current methods, according to a new paper. The paper synthesizes, reviews and analyzes between 40 and 50 studies on the subject to provide a big-picture look of the status of nanotechnologies in coastal oil spill response. The researchers also present their own suggestions and identifying research gaps between using nanomaterials in the lab and how they can be used in real-world applications.

Listening for multiple mental health disorders

Matter and energy from Science Daily Feed - Tue, 02/04/2025 - 10:20am
Researchers develop machine learning tools that screen for co-morbid anxiety disorders and major depressive disorder using acoustic voice signals. The team spoke to participants with and without co-morbid AD/MDD and recorded them using a secure telehealth platform. The participants were given a semantic verbal fluency test, in which they were required to name as many animals as possible within a time limit. The team extracted acoustic and phonemic features from the recordings and applied machine learning technique to distinguish subjects with and without comorbid AD/MDD. The results confirmed that a one-minute semantic VFT can be reliably used to screen for AD/MDD.

Straight shot: Hubble investigates galaxy with nine rings

Space and time from Science Daily Feed - Tue, 02/04/2025 - 10:20am
NASA's Hubble Space Telescope has captured a cosmic bullseye! The gargantuan galaxy LEDA 1313424 is rippling with nine star-filled rings after an 'arrow' -- a far smaller blue dwarf galaxy -- shot through its heart. Astronomers using Hubble identified eight visible rings, more than previously detected by any telescope in any galaxy, and confirmed a ninth using data from the W. M. Keck Observatory in Hawaii. Previous observations of other galaxies show a maximum of two or three rings.
