Published Trapped in the middle: Billiards with memory
(via sciencedaily.com) Original source Adding one simple rule to an idealized game of billiards leads to a wealth of intriguing mathematical questions, as well as applications in the physics of living organisms. Researchers are discovering the fascinating dynamics of billiards with memory.
Published Tropical coral-infecting parasites discovered in cold marine ecosystems
(via sciencedaily.com) Original source Parasites thought only to infect tropical coral reefs have been discovered in a large variety of creatures in cold marine ecosystems along the Northeast Pacific, according to new research.
Published Star Trek's Holodeck recreated using ChatGPT and video game assets
(via sciencedaily.com) Original source Star Trek's Holodeck is no longer just science fiction. Using AI, engineers have created a tool that can generate 3D environments, prompted by everyday language.
Published Method to extract useful proteins from beer-brewing leftovers
(via sciencedaily.com) Original source Researchers have created a method that extracts over 80 percent of the available protein in grain leftovers from brewing beer, commonly known as brewers' spent grain.
Published Breakthrough promises secure quantum computing at home
(via sciencedaily.com) Original source The full power of next-generation quantum computing could soon be harnessed by millions of individuals and companies, thanks to a breakthrough guaranteeing security and privacy. This advance promises to unlock the transformative potential of cloud-based quantum computing.
Published Twinkle twinkle baby star, 'sneezes' tell us how you are
(via sciencedaily.com) Original source Researchers have found that baby stars discharge plumes of gas, dust, and magnetic flux from their protostellar disk. The protostellar disk that surrounds developing stars are constantly penetrated by magnetic flux, and if too much magnetic flux remained, the resulting object would generate a magnetic field stronger than any observed protostar. These newly discovered discharges of magnetic flux, or 'sneezes' as the researchers describes them, may be a vital step in proper star formation.
Published Oxidant pollutant ozone removes mating barriers between fly species
(via sciencedaily.com) Original source Researchers show that ozone levels, such as those found in many places on hot summer days today, destroy the sex pheromones of fruit fly species. As a result, some natural mating boundaries maintained by species-specific pheromones no longer exist. The research team has shown in experiments that flies of different species mate when exposed to ozone and produce hybrid offspring. Since most of these offspring are unable to reproduce, the results could provide another explanation for the global decline of insects.
Published Genetic underpinnings of environmental stress identified in model plant
(via sciencedaily.com) Original source Researchers have identified 14 genes that thale cress -- a plant commonly used in genetic investigations since its genome is well documented -- express more when responding to five specific stressors, as well as eight genes that the plant suppresses.
Published Geobiology: New placozoan habitat discovered
(via sciencedaily.com) Original source Traces of DNA in the stomachs of predatory snails give a team og geobiologists new insights into the ecology of placozoans.
Published The hidden role of the Milky Way in ancient Egyptian mythology
(via sciencedaily.com) Original source Astrophysicists shed light on the relationship between the Milky Way and the Egyptian sky-goddess Nut. The paper draws on ancient Egyptian texts and simulations to argue that the Milky Way might have shone a spotlight, as it were, on Nut's role as the sky. It proposes that in winter, the Milky Way highlighted Nut's outstretched arms, while in summer, it traced her backbone across the heavens.
Published New drug prevents flu-related inflammation and lung damage
(via sciencedaily.com) Original source Findings show a newly created drug can prevent runaway inflammation while still allowing the immune system to handle the virus, even when given late into infection.
Published The genesis of our cellular skeleton, image by image
(via sciencedaily.com) Original source Cells contain various specialized structures -- such as the nucleus, mitochondria or peroxisomes -- known as 'organelles'. Tracing their genesis and determining their structure is fundamental to understanding cell function and the pathologies linked to their dysfunction.
Published Researchers discover how we perceive bitter taste
(via sciencedaily.com) Original source A new study reveals the detailed protein structure of the TAS2R14, a bitter taste receptor that allows us to perceive bitter taste. In addition to solving the structure of this taste receptor, the researchers were also able to determine where bitter-tasting substances bind to TAS2R14 and how they activate them. The findings may lead to the development of drugs that targeting taste receptors.
Published Cockayne syndrome: New insights into cellular DNA repair mechanism
(via sciencedaily.com) Original source Researchers decode repair mechanism during transcription of genetic information.
Published Revolutionary molecular device unleashes potential for targeted drug delivery and self-healing materials
(via sciencedaily.com) Original source In a new breakthrough that could revolutionise medical and material engineering, scientists have developed a first-of-its-kind molecular device that controls the release of multiple small molecules using force.
Published A microbial plastic factory for high-quality green plastic
(via sciencedaily.com) Original source Engineered bacteria can produce a plastic modifier that makes renewably sourced plastic more processable, more fracture resistant and highly biodegradable even in sea water. The development provides a platform for the industrial-scale, tunable production of a material that holds great potential for turning the plastic industry green.
Published 'Teacher Toads' can save native animals from toxic cane toads
(via sciencedaily.com) Original source Scientists from Macquarie University have come up with an innovative way to stop cane toads killing native wildlife by training goannas to avoid eating the deadly amphibians.
Published Machine learning method reveals chromosome locations in individual cell nucleus
(via sciencedaily.com) Original source Researchers have made a significant advancement toward understanding how the human genome is organized inside a single cell. This knowledge is crucial for analyzing how DNA structure influences gene expression and disease processes.
Published Do some mysterious bones belong to gigantic ichthyosaurs?
(via sciencedaily.com) Original source Several similar large, fossilized bone fragments have been discovered in various regions across Western and Central Europe since the 19th century. The animal group to which they belonged is still the subject of much debate to this day. A study could now settle this dispute once and for all: The microstructure of the fossils indicates that they come from the lower jaw of a gigantic ichthyosaur. These animals could reach 25 to 30 meters in length, a similar size to the modern blue whale.
Published Bacteria in cancer unmasked
(via sciencedaily.com) Original source Researchers have compiled a detailed catalogue of bacteria living in cancer metastases. Having analyzed over 4000 tumors, they shed light on the diversity of these co-inhabitants and how they might interact with cancer cells and their surroundings. For example, certain bacteria were linked to a worse response to immunotherapy. This study paves the way to a better understanding of how bacteria help or hinder cancer (therapy), and how we can use this for patients' advantage.
