Published Whale-SETI: Groundbreaking encounter with humpback whales reveals potential for nonhuman intelligence communication
(via sciencedaily.com) Original source A team of scientists had a close encounter with a non-human (aquatic) intelligence. The Whale-SETI team has been studying humpback whale communication systems in an effort to develop intelligence filters for the search for extraterrestrial intelligence. In response to a recorded humpback 'contact' call played into the sea via an underwater speaker, a humpback whale named Twain approached and circled the team's boat, while responding in a conversational style to the whale 'greeting signal.' During the 20-minute exchange, Twain responded to each playback call and matched the interval variations between each signal.
Published Single-use e-cigarettes contain batteries that last hundreds of cycles despite being discarded
(via sciencedaily.com) Original source While the lithium-ion batteries in disposable electronic cigarettes are discarded after a single use, they can continue to perform at high capacity for hundreds of cycles, according to a new study. The analysis highlights a growing environmental threat from these increasingly popular vape pens, which are not designed to be recharged.
Published How a drought led to the rise of skateboarding in 1970s California
(via sciencedaily.com) Original source Why did professional skateboarding arise in southern California in the 1970s? Was it a coincidence, or was it a perfect storm of multiple factors? It's fairly well-known that a drought in southern California in the mid-1970s led to a ban on filling backyard swimming pools, and these empty pools became playgrounds for freestyle skateboarders in the greater Los Angeles area. But a new cross-disciplinary study shows that beyond the drought, it was the entanglement of environmental, economic and technological factors that led to the explosive rise of professional skateboarding culture in the 1970s.
Published This Japanese 'dragon' terrorized ancient seas
(via sciencedaily.com) Original source Researchers have described a Japanese mosasaur the size of a great white shark that terrorized Pacific seas 72 million years ago. The mosasaur was named for the place where it was found, Wakayama Prefecture. Researchers call it the Wakayama Soryu, which means blue dragon.
Published Extremely rare bird captured on film
(via sciencedaily.com) Original source A striking and extremely rare half-female, half-male bird has been spotted by a zoologist.
Published Have researchers found the missing link that explains the mysterious phenomenon known as fairy circles?
(via sciencedaily.com) Original source Fairy circles, a nearly hexagonal pattern of bare-soil circular gaps in grasslands, initially observed in Namibia and later in other parts of the world, have fascinated and baffled scientists for years. New research suggests that all theories to date have overlooked the coupling between two robust mechanisms essential for understanding ecosystem response: phenotypic plasticity at the level of a single plant, and spatial self-organization in vegetation patterns at the level of a plant population.
Published AI chatbot shows potential as diagnostic partner
(via sciencedaily.com) Original source Physician-investigators compared a chatbot's probabilistic reasoning to that of human clinicians. The findings suggest that artificial intelligence could serve as useful clinical decision support tools for physicians.
Published When is an aurora not an aurora?
(via sciencedaily.com) Original source While auroras occur at high latitude, the associated phenomena Steve and the picket fence occur farther south and at lower altitude. Their emissions also differ from aurora. A physics graduate student has proposed a physical mechanism behind these emissions, and a rocket launch to test the theory. She argues that an electric field in the upper atmosphere parallel to Earth's magnetic field could explain the green picket fence spectrum and perhaps Steve and the enhanced aurora.
Published Veins of bacteria could form a self-healing system for concrete infrastructure
(via sciencedaily.com) Original source In hopes of producing concrete structures that can repair their cracks, researchers are putting a new twist on an old trick for improving the durability of concrete. Fiber reinforcement has been around since the first masons were mixing horsehair into their mud. But this research team is taking this method to the next level by turning reinforcing fibers into a living tissue system that rushes concrete-healing bacteria to the site of cracks to repair the damage.
Published Immersive VR goggles for mice unlock new potential for brain science
(via sciencedaily.com) Original source New miniature virtual reality (VR) goggles provide more immersive experiences for mice living in laboratory settings. By more faithfully simulating natural environments, the researchers can more accurately and precisely study the neural circuitry that underlies behavior. Compared to current state-of-the-art systems, which simply surround mice with computer or projection screens, the new goggles provide a leap in advancement.
Published World's first logical quantum processor
(via sciencedaily.com) Original source A team has realized a key milestone in the quest for stable, scalable quantum computing. For the first time, the team has created a programmable, logical quantum processor, capable of encoding up to 48 logical qubits, and executing hundreds of logical gate operations. Their system is the first demonstration of large-scale algorithm execution on an error-corrected quantum computer, heralding the advent of early fault-tolerant, or reliably uninterrupted, quantum computation.
Published Scholars say it's time to declare a new epoch on the moon, the 'lunar Anthropocene'
(via sciencedaily.com) Original source According to anthropologists and geologists, it's time to acknowledge humans have become the dominant force shaping the moon's environment by declaring a new geological epoch for the moon: the Lunar Anthropocene. They argue the new epoch may have dawned in 1959 when the USSR's unmanned spacecraft Luna 2 alighted on the lunar surface.
Published New genes can arise from nothing
(via sciencedaily.com) Original source The complexity of living organisms is encoded within their genes, but where do these genes come from? Researchers resolved outstanding questions regarding the origin of small regulatory genes, and described a mechanism that creates their DNA palindromes. Under suitable circumstances, these palindromes evolve into microRNA genes.
Published ChatGPT often won't defend its answers -- even when it is right
(via sciencedaily.com) Original source ChatGPT may do an impressive job at correctly answering complex questions, but a new study suggests it may be absurdly easy to convince the AI chatbot that it's in the wrong.
Published It turns out, this fossil 'plant' is really a fossil baby turtle
(via sciencedaily.com) Original source Researchers re-examined a plant fossil found decades ago in Colombia and realized that it wasn't a plant at all: it's a fossilized baby turtle. It's a rare find, because juvenile turtles' shells are soft and often don't fossilize well.
Published Wild birds lead people to honey -- and learn from them
(via sciencedaily.com) Original source A study finds the greater honeyguide can learn distinct vocal signals to help people in Africa locate bee colonies. In parts of Africa, people communicate with a wild bird -- the greater honeyguide -- in order to locate bee colonies and harvest their stores of honey and beeswax. It's a rare example of cooperation between humans and wild animals, and a potential instance of cultural coevolution.
Published Baboons in captivity in Ancient Egypt: insights from collection of mummies

Published Jays jump in while crows hold out for the treat
(via sciencedaily.com) Original source New research has found that two similar species of birds behave very differently around their favorite food when they have company. Biologists compared the behavior of two species of corvids, Eurasian jays and New Caledonian crows, both capable of displaying self-control through delayed gratification. The researchers found that jays will settle for an immediate, less preferred food option when another bird is present, while crows will always hold out for their favorite food, regardless of the social context.
