Published Small, cool and sulfurous exoplanet may help write recipe for planetary formation
(via sciencedaily.com) Original source Astronomers observing exoplanet GJ 3470 b saw evidence of water, carbon dioxide, methane and sulfur dioxide. Astronomers hope the discovery of this exoplanet's sulfurous atmosphere will advance our understanding of how planets forms.
Published In new experiment, scientists record Earth's radio waves from the moon
(via sciencedaily.com) Original source Odysseus, a tenacious lander built by the company Intuitive Machines, almost didn't make it to the moon. But an experiment aboard the spacecraft managed to capture an image of Earth as it might look to observers on a planet far from our own.
Published Lake under Mars ice cap unlikely
(via sciencedaily.com) Original source Researchers have provided a simple and comprehensive -- if less dramatic -- explanation for bright radar reflections initially interpreted as liquid water beneath the ice cap on Mars' south pole.
Published Earth and space share the same turbulence
(via sciencedaily.com) Original source Researchers have discovered that the turbulence found in the thermosphere -- known as the gateway to space -- and turbulence in the troposphere, here closer to sea level, follow the same physical laws despite having drastically different atmospheric compositions and dynamics.
Published Discovery highlights 'critical oversight' in perceived security of wireless networks
(via sciencedaily.com) Original source A research team has uncovered an eavesdropping security vulnerability in high-frequency and high-speed wireless backhaul links, widely employed in critical applications such as 5G wireless cell phone signals and low-latency financial trading on Wall Street.
Published Researchers upend theory about the formation of the Milky Way Galaxy
(via sciencedaily.com) Original source Research reveals a shocking discovery about the history of our universe: the Milky Way Galaxy's last major collision occurred billions of years later than previously thought.
Published Seeking social proximity improves flight routes among pigeons
(via sciencedaily.com) Original source A new study looked at the social influences on pigeon flight routes. Comparing the flight patterns of pairs of pigeons to a computer model, the researcher found that flight paths are improved as younger birds learn the route from older birds and also make route improvements, leading to overall more efficient routes over generations.
Published Planet-forming disks around very low-mass stars are different
(via sciencedaily.com) Original source Using the James Webb Space Telescope, a team of astronomers studied the properties of a planet-forming disk around a young and very low-mass star. The results reveal the richest hydrocarbon composition seen to date in a protoplanetary disk, including the first extrasolar detection of ethane and a relatively low abundance of oxygen-bearing species. By including previous similar detections, this finding confirms a trend of disks around very low-mass stars to be chemically distinct from those around more massive stars like the Sun, influencing the atmospheres of planets forming there.
Published AIs are irrational, but not in the same way that humans are
(via sciencedaily.com) Original source Large Language Models behind popular generative AI platforms like ChatGPT gave different answers when asked to respond to the same reasoning test and didn't improve when given additional context, finds a new study.
Published Olivine unlocks the secrets of the Moon's interior
(via sciencedaily.com) Original source New partitioning coefficients of first-transition row elements, Ga and Ge between olivine and silicate melt have been reported. New high-temperature experiments have investigated the effects of oxygen fugacity and iron content on these partition coefficients. This newly compiled dataset offers insights into interpreting trace elements found in olivine phenocrysts within lunar basalts, shedding light on the deep interior composition of the Moon.
Published Novel method of detecting high-frequency gravitational waves in planetary magnetospheres
(via sciencedaily.com) Original source A groundbreaking method of detecting high-frequency gravitational waves (HFGWs) has been proposed. The team's innovative approach may enable the successful detection of HFGWs by utilizing existing and technologically feasible astronomical telescopes in planetary magnetosphere, opening up new possibilities for studying the early universe and violent cosmic events in an effective and technically viable way.
Published Scientists detect slowest-spinning radio emitting neutron star ever recorded
(via sciencedaily.com) Original source Scientists have detected what they believe to be a neutron star spinning at an unprecedentedly slow rate -- slower than any of the more than 3,000 radio emitting neutron stars measured to date.
Published 'Weird' new planet retained atmosphere despite nearby star's relentless radiation
(via sciencedaily.com) Original source A rare exoplanet that should have been stripped down to bare rock by its nearby host star's intense radiation somehow grew a puffy atmosphere instead -- the latest in a string of discoveries forcing scientists to rethink theories about how planets age and die in extreme environments. Nicknamed 'Phoenix' for its ability to survive its red giant star's radiant energy discovered planet illustrates the vast diversity of solar systems and the complexity of planetary evolution -- especially at the end of stars' lives.
Published Using AI to decode dog vocalizations
(via sciencedaily.com) Original source Have you ever wished you could understand what your dog is trying to say to you? Researchers are exploring the possibilities of AI, developing tools that can identify whether a dog's bark conveys playfulness or aggression.
Published New model allows a computer to understand human emotions
(via sciencedaily.com) Original source Researchers have developed a model that enables computers to interpret and understand human emotions, utilizing principles of mathematical psychology. In the future, the model can help the computer to adapt its own behavior and guide an irritated or anxious user in different ways. The implications of such technology are profound, offering a glimpse into a future where computers are not merely tools, but empathetic partners in user interaction.
Published New open-source platform allows users to evaluate performance of AI-powered chatbots
(via sciencedaily.com) Original source Researchers have developed a platform for the interactive evaluation of AI-powered chatbots such as ChatGPT. A team of computer scientists, engineers, mathematicians and cognitive scientists developed an open-source evaluation platform called CheckMate, which allows human users to interact with and evaluate the performance of large language models (LLMs).
Published Researchers call for strengthening sustainability regulations in laws governing space exploration
(via sciencedaily.com) Original source Researchers call for strengthening existing planetary protection policies beyond the space surrounding Earth to include requirements for preserving the Lunar and Martian environments.
Published Martian meteorites deliver a trove of information on Red Planet's structure
(via sciencedaily.com) Original source Mars has a distinct structure in its mantle and crust with discernible reservoirs, and this is known thanks to meteorites that scientists have analyzed. These results are important for understanding not only how Mars formed and evolved, but also for providing precise data that can inform recent NASA missions like Insight and Perseverance and the Mars Sample Return.
Published Children's visual experience may hold key to better computer vision training
(via sciencedaily.com) Original source A novel, human-inspired approach to training artificial intelligence (AI) systems to identify objects and navigate their surroundings could set the stage for the development of more advanced AI systems to explore extreme environments or distant worlds, according to new research.
Published This self-powered sensor could make MRIs more efficient
(via sciencedaily.com) Original source MRI scans are commonly used to diagnose a variety of conditions, anything from liver disease to brain tumors. But, as anyone who has been through one knows, patients must remain completely still to avoid blurring the images and requiring a new scan. A prototype device could change that. The self-powered sensor detects movement and shuts down an MRI scan in real time, improving the process for patients and technicians.
