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 Liquid metal-based electronic logic device that mimics intelligent prey-capture mechanism of Venus flytrap
(via sciencedaily.com) Original source A research team has developed a liquid metal-based electronic logic device that mimics the intelligent prey-capture mechanism of Venus flytraps. Exhibiting memory and counting properties, the device can intelligently respond to various stimulus sequences without the need for additional electronic components. The intelligent strategies and logic mechanisms in the device provide a fresh perspective on understanding 'intelligence' in nature and offer inspiration for the development of 'embodied intelligence'.
Published Better farming through nanotechnology
(via sciencedaily.com) Original source Advanced technologies enable the controlled release of medicine to specific cells in the body. Scientists argue these same technologies must be applied to agriculture if growers are to meet increasing global food demands.
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 Exotic black holes could be a byproduct of dark matter
(via sciencedaily.com) Original source In the first quintillionth of a second, the universe may have sprouted microscopic black holes with enormous amounts of nuclear charge, MIT physicists propose. The gravitational pull from these tiny, invisible objects could potentially explain all the dark matter that we can't see today.
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 A technique for more effective multipurpose robots
(via sciencedaily.com) Original source MIT researchers developed a technique to combine robotics training data across domains, modalities, and tasks using generative AI models. They create a combined strategy from several different datasets that enables a robot to learn to perform new tasks in unseen environments.
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 Enhancing nanofibrous acoustic energy harvesters with artificial intelligence
(via sciencedaily.com) Original source Scientists have employed artificial intelligence techniques to improve the design and production of nanofibers used in wearable nanofiber acoustic energy harvesters (NAEH). These acoustic devices capture sound energy from the environment and convert it into electrical energy, which can then be applied in useful devices, such as hearing aids.
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 Designing environments that are robot-inclusive
(via sciencedaily.com) Original source To overcome issues associated with real-life testing, researchers successfully demonstrated the use of digital twin technology within robot simulation software in assessing a robot's suitability for deployment in simulated built environments.
Published AI-controlled stations can charge electric cars at a personal price
(via sciencedaily.com) Original source As more and more people drive electric cars, congestion and queues can occur when many people need to charge at the same time. A new study shows how AI-controlled charging stations, through smart algorithms, can offer electric vehicle users personalized prices, and thus minimize both price and waiting time for customers. But the researchers point to the importance of taking the ethical issues seriously, as there is a risk that the artificial intelligence exploits information from motorists.
Published Glimpses of a volcanic world: New telescope images of Jupiter's moon Io rival those from spacecraft
(via sciencedaily.com) Original source Combining a new imaging instrument with the powerful adaptive optics capabilities of the Large Binocular Telescope, astronomers have captured a volcanic event on Jupiter's moon Io at a resolution never before achieved with Earth-based observations.
Published Medium and mighty: Intermediate-mass black holes can survive in globular clusters
(via sciencedaily.com) Original source New research demonstrated a possible formation mechanism of intermediate-mass black holes in globular clusters, star clusters that could contain tens of thousands or even millions of tightly packed stars. The first ever star-by-star massive cluster-formation simulations revealed that sufficiently dense molecular clouds, the 'birthing nests' of star clusters, can give birth to very massive stars that evolve into intermediate-mass black holes.
Published NASA's James Webb Space Telescope finds most distant known galaxy
(via sciencedaily.com) Original source Over the last two years, scientists have used NASA's James Webb Space Telescope to explore what astronomers refer to as Cosmic Dawn -- the period in the first few hundred million years after the big bang where the first galaxies were born.
Published Moon orbiting 'dinky' asteroid is actually two tiny moons stuck together
(via sciencedaily.com) Original source The moon orbiting the asteroid Dinkinesh is actually two tiny moons stuck together. Collectively called 'Selam,' the two moonlets bring new insight into the complex processes behind planetary formation and evolution.
Published The case of the missing black holes
(via sciencedaily.com) Original source Researchers have applied the well-understood and highly verified quantum field theory, usually applied to the study of the very small, to a new target, the early universe. Their exploration led to the conclusion that there ought to be far fewer miniature black holes than most models suggest, though observations to confirm this should soon be possible. The specific kind of black hole in question could be a contender for dark matter.
Published New technique offers more precise maps of the Moon's surface
(via sciencedaily.com) Original source A new study may help redefine how scientists map the surface of the Moon, making the process more streamlined and precise than ever before.
Published Public have no difficulty getting to grips with an extra thumb, study finds
(via sciencedaily.com) Original source Researchers have shown that members of the public have little trouble in learning very quickly how to use a third thumb -- a controllable, prosthetic extra thumb -- to pick up and manipulate objects. The team tested the robotic device on a diverse range of participants, which they say is essential for ensuring new technologies are inclusive and can work for everyone.
