Venus had Earth-like plate tectonics billions of years ago, study suggests      (via sciencedaily.com)     Original source 

Venus, may have once had tectonic plate movements similar to those believed to have occurred on early Earth, a new study found. The finding sets up tantalizing scenarios regarding the possibility of early life on Venus, its evolutionary past and the history of the solar system.

Deep learning speeds up galactic calculations      (via sciencedaily.com)     Original source 

Supernovae, exploding stars, play a critical role in the formation and evolution of galaxies. However, key aspects of them are notoriously difficult to simulate accurately in reasonably short amounts of time. For the first time, a team of researchers apply deep learning to the problem of supernova simulation. Their approach can speed up the simulation of supernovae, and therefore of galaxy formation and evolution as well. These simulations include the evolution of the chemistry which led to life.

A team of scientists has used multiple space and ground-based telescopes to observe an exceptionally bright gamma-ray burst, GRB 230307A, and identify the neutron star merger that generated an explosion that created the burst. Webb also helped scientists detect the chemical element tellurium in the explosion's aftermath.

Raining cats and dogs: Global precipitation patterns a driver for animal diversity      (via sciencedaily.com)     Original source 

A team has identified several factors to help answer a fundamental ecological question: why is there a ridiculous abundance of species some places on earth and a scarcity in others? What factors, exactly, drive animal diversity? They discovered that what an animal eats (and how that interacts with climate) shapes Earth's diversity.

Finding the genes that help kingfishers dive without hurting their brains      (via sciencedaily.com)     Original source 

Scientists studied the genomes of 30 kingfisher species to try to identify the genes that allow kingfishers to dive headfirst into water without huring their brains. The researchers found that the diving birds have unusual mutations to the genes that produce tau: a protein that helps stabilize tiny structures in the brain, but which can build up in humans with traumatic brain injuries or Alzheimer's disease. The researchers suspect that these variations in the kingfishers' tau proteins might protect their brains when they dive.

How quantum light 'sees' quantum sound      (via sciencedaily.com)     Original source 

Researchers have proposed a new way of using quantum light to 'see' quantum sound. A new paper reveals the quantum-mechanical interplay between vibrations and particles of light, known as photons, in molecules. It is hoped that the discovery may help scientists better understand the interactions between light and matter on molecular scales. And it potentially paves the way for addressing fundamental questions about the importance of quantum effects in applications ranging from new quantum technologies to biological systems.

Fungal evolution discovered: Mycena can now invade living hosts      (via sciencedaily.com)     Original source 

Biologists have long known mushrooms of the genus Mycena, commonly known as bonnet mushrooms, as fungi that live off of dead trees and plants. New research demonstrates that bonnets can also find their ways into young, healthy trees and plants, where they try to cooperate. In doing so, they have made an evolutionary leap which challenges our understanding of the ecological roles of fungi.

Mummified mice discovered atop sky-high Andean volcanoes      (via sciencedaily.com)     Original source 

Scientists have uncovered 13 mummified cadavers of mice from the summits of Andean volcanoes that stretch nearly 4 miles above sea level. Analyses of the mummies, combined with the capture of live specimens, suggest that the mice scaled the Mars-like peaks on their own -- and are somehow managing to live on them.

The fossils of a 170-million-year-old ancient marine reptile from the Age of Dinosaurs have been identified as the oldest-known mega-predatory pliosaur -- a group of ocean-dwelling reptiles closely related to the famous long-necked plesiosaurs. The findings are rare and add new knowledge to the evolution of plesiosaurs.

What do new moms and roaches have in common?      (via sciencedaily.com)     Original source 

Researchers are studying the dramatic physical transformation that some insects undergo to give birth to live young. This includes suppressing their immune systems to accommodate babies, which is something some insects and people have in common. Understanding how these systems work can help improve treatments for fibromyalgia and other immune disorders. An international team of researchers has examined the complex structural and physiological changes that take place in Hawaii's beetle-mimic cockroaches, which give birth to live young.
