Published Neanderthal gene variants associated with greater pain sensitivity
(via sciencedaily.com) Original source People who carry three gene variants that have been inherited from Neanderthals are more sensitive to some types of pain, according to a new study.
Published Unifying matter, energy and consciousness
(via sciencedaily.com) Original source Understanding the interplay between consciousness, energy and matter could bring important insights to our fundamental understanding of reality.
Published Ginger pigment molecules found in fossil frogs
(via sciencedaily.com) Palaeontologists discover molecular evidence of phaeomelanin, the pigment that produces ginger coloration. Phaeomelanin is now toxic to animals – this discovery may be first step in understand its evolution.
Published Oldest fossil human footprints in North America confirmed
(via sciencedaily.com) Original source New research reaffirms that human footprints found in White Sands National Park, NM, date to the Last Glacial Maximum, placing humans in North America thousands of years earlier than once thought. In September 2021, scientists announced that ancient human footprints discovered in White Sands National Park were between 21,000 and 23,000 years old. This discovery pushed the known date of human presence in North America back by thousands of years and implied that early inhabitants and megafauna co-existed for several millennia before the terminal Pleistocene extinction event. In a follow-up study, researchers used two new independent approaches to date the footprints, both of which resulted in the same age range as the original estimate.
Published New type of tiny wasp comes with mysterious, cloud-like structures at ends of antennae
(via sciencedaily.com) Original source Fossil researchers have discovered a novel genus and species of tiny wasp with a mysterious, bulbous structure at the end of each antenna.
Published Could future AI crave a favorite food?
(via sciencedaily.com) Original source Can artificial intelligence (AI) get hungry? Develop a taste for certain foods? Not yet, but a team of researchers is developing a novel electronic tongue that mimics how taste influences what we eat based on both needs and wants, providing a possible blueprint for AI that processes information more like a human being.
Published These robots helped explain how insects evolved two distinct strategies for flight
(via sciencedaily.com) Original source Robots helped achieve a major breakthrough in our understanding of how insect flight evolved. The study is a result of a six-year long collaboration between roboticists and biophysicists.
Published Insect cyborgs: Towards precision movement
(via sciencedaily.com) Original source Insect cyborgs may sound like something straight out of the movies, but hybrid insect computer robots, as they are scientifically called, could pioneer a new future for robotics. It involves using electrical stimuli to control an insect’s movement. Now, an international research group has conducted a study on the relationship between electrical stimulation in stick insects' leg muscles and the resulting torque (the twisting force that causes the leg to move).
Published Power of rhythm as a design element in evolution and robotics
(via sciencedaily.com) Original source As the internet quickly fills with viral videos of futuristic robots darting and racing around like the animals they’re built to mimic, researchers say that there’s an element of their movement’s programming that should not be overlooked: rhythm.
Published Instant evolution: AI designs new robot from scratch in seconds
(via sciencedaily.com) Original source Researchers developed the first AI to date that can intelligently design robots from scratch by compressing billions of years of evolution into mere seconds. It's not only fast but also runs on a lightweight computer and designs wholly novel structures from scratch — without human-labeled, bias-filled datasets.
Published Unleashing the power of AI to track animal behavior
(via sciencedaily.com) Scientists have created a non-invasive movement tracking method called GlowTrack that uses fluorescent dye markers to train artificial intelligence to capture movement, from a single mouse digit to the human hand. GlowTrack has applications spanning biology, robotics, medicine, and beyond.
Published One-hour training is all you need to control a third robotic arm, study finds
(via sciencedaily.com) A new study has found that people can learn to use supernumerary robotic arms as effectively as working with a partner in just one hour of training.
Published Efficient training for artificial intelligence
(via sciencedaily.com) New physics-based self-learning machines could replace the current artificial neural networks and save energy.
Published Dinosaur feathers reveal traces of ancient proteins
(via sciencedaily.com) Original source Palaeontologists have discovered X-ray evidence of proteins in fossil feathers that sheds new light on feather evolution.
Published Ritual use of human remains dating from the Neolithic
(via sciencedaily.com) Original source An international study has documented post-mortem bone modifications not linked to consumption.
Published Shape-changing smart speaker lets users mute different areas of a room
(via sciencedaily.com) A team has developed a shape-changing smart speaker, which uses self-deploying microphones to divide rooms into speech zones and track the positions of individual speakers.
Published Scientists successfully maneuver robot through living lung tissue
(via sciencedaily.com) Scientists have shown that their steerable lung robot can autonomously maneuver the intricacies of the lung, while avoiding important lung structures.
Published Archaeologists discover world's oldest wooden structure
(via sciencedaily.com) Original source Half a million years ago, earlier than was previously thought possible, humans were building structures made of wood, according to new research.
Published Slow growth in crocodile ancestors pre-dated their semi-aquatic lifestyle
(via sciencedaily.com) Original source A groundbreaking study is reshaping our understanding of crocodile evolution by pinpointing the onset of slow growth rates to the Late Triassic period, much earlier than the previously assumed Early Jurassic timeline. The research highlights newly discovered fossil crocodile ancestors (known as crocodylomorphs) that exhibited slow growth rates, similar to modern-day crocodilians. Intriguingly, these early crocodylomorphs were not the lethargic, semi-aquatic creatures we are familiar with today; they were small, active, and fully terrestrial. The study also suggests that this slow-growth strategy was not a mere evolutionary quirk but a survival mechanism, as only the slow-growing crocodylomorphs managed to survive the End-Triassic mass extinction. This stands in stark contrast to the fast-growing dinosaurs of the same era, setting the stage for the divergent evolutionary paths that would later define their modern descendants.
Published Prehistoric fish fills 100 million year gap in evolution of the skull
(via sciencedaily.com) Original source X-rays of an ancient jawless fish shows earliest-known example of internal cartilage skull, unlike that of any other known vertebrate.
