Published Atmospheric pressure changes could be driving Mars' elusive methane pulses
(via sciencedaily.com) Original source New research shows that atmospheric pressure fluctuations that pull gases up from underground could be responsible for releasing subsurface methane into Mars' atmosphere; knowing when and where to look for methane can help the Curiosity rover search for signs of life.
Published Records of cometary dust hitting the asteroid Ryugu
(via sciencedaily.com) Original source The Hayabusa2 mission that collected samples from the asteroid Ryugu has provided a treasure trove of insights into our solar system. After analyzing samples further, a team of researchers have unearthed evidence that cometary organic matter was transported from space to the near-Earth region.
Published Lightest black hole or heaviest neutron star? MeerKAT uncovers a mysterious object in Milky Way
(via sciencedaily.com) Original source An international team of astronomers have found a new and unknown object in the Milky Way that is heavier than the heaviest neutron stars known and yet simultaneously lighter than the lightest black holes known.
Published Mini-robots modeled on insects may be smallest, lightest, fastest ever developed
(via sciencedaily.com) Original source Two insect-like robots, a mini-bug and a water strider may be the smallest, lightest and fastest fully functional micro-robots ever known to be created. Such miniature robots could someday be used for work in areas such as artificial pollination, search and rescue, environmental monitoring, micro-fabrication or robotic-assisted surgery. Reporting on their work in the proceedings of the IEEE Robotics and Automation Society's International Conference on Intelligent Robots and Systems, the mini-bug weighs in at eight milligrams while the water strider weighs 55 milligrams. Both can move at about six millimeters a second.
Published Moon rocks with unique dust found
(via sciencedaily.com) Original source A research team has for the first time discovered anomalous meter-sized rocks on the lunar surface that are covered in dust and presumably exhibit unique properties -- such as magnetic anomalies. These findings help to understand the processes that form and change the lunar crust.
Published Study identifies new findings on implant positioning and stability during robotic-assisted knee revision surgery
(via sciencedaily.com) Original source An innovative study explores the use of robotic-assisted joint replacement in revision knee scenarios, comparing the pre- and post-revision implant positions in a series of revision total knee arthroplasties (TKA) using a state-of-the-art robotic arm system.
Published Astronomers detect oldest black hole ever observed
(via sciencedaily.com) Original source Researchers have discovered the oldest black hole ever observed, dating from the dawn of the universe, and found that it is 'eating' its host galaxy to death.
Published The metalens meets the stars
(via sciencedaily.com) Original source Researchers have developed a 10-centimeter-diameter glass metalens that can image the sun, the moon and distant nebulae with high resolution. It is the first all-glass, large-scale metalens in the visible wavelength that can be mass produced using conventional CMOS fabrication technology.
Published Study delivers detailed photos of galaxies' inner structures
(via sciencedaily.com) Original source High-resolution images captured by the James Webb Space Telescope are offering powerful insights into the complex dust patterns of nearby star-forming galaxies.
Published Space solar power project ends first in-space mission with successes and lessons
(via sciencedaily.com) Original source A 10-month mission demonstrated three elements of the plan to beam solar power from space to Earth.
Published Astronomers produce most sensitive radio image ever of ancient star cluster
(via sciencedaily.com) Original source Astronomers have created the most sensitive radio image ever of a globular cluster, an ancient ball of tightly-packed stars.
Published 'Smart glove' can boost hand mobility of stroke patients
(via sciencedaily.com) Original source This month, a group of stroke survivors in British Columbia will test a new technology designed to aid their recovery, and ultimately restore use of their limbs and hands. Participants will wear a new groundbreaking 'smart glove' capable of tracking their hand and finger movements during rehabilitation exercises.
Published Discovery changes understanding of water's history on the Moon
(via sciencedaily.com) Original source New research shows the early lunar crust which makes up the surface of the Moon was considerably enriched in water more than 4 billion years ago, counter to previously held understanding.
Published Research sheds new light on Moon rock formation solving major puzzle in lunar geology
(via sciencedaily.com) Original source New research has cracked a vital process in the creation of a unique rock type from the Moon. The discovery explains its signature composition and very presence on the lunar surface at all, unraveling a mystery which has long-eluded scientists.
Published Earth-sized planet discovered in 'our solar backyard'
(via sciencedaily.com) Original source Astronomers have discovered a planet closer and younger than any other Earth-sized world yet identified. It's a remarkably hot world whose proximity to our own planet and to a star like our sun mark it as a unique opportunity to study how planets evolve.
Published NASA scientists discover a novel galactic 'fossil'
(via sciencedaily.com) Original source Researchers at NASA's Goddard Space Flight Center have discovered X-ray activity that sheds light on the evolution of galaxies.
Published Our surprising magnetic galaxy
(via sciencedaily.com) Original source A team of astronomers has created the first-ever map of magnetic field structures within a spiral arm of our Milky Way galaxy. Previous studies on galactic magnetic fields only gave a very general picture, but the new study reveals that magnetic fields in the spiral arms of our galaxy break away from this general picture significantly and are tilted away from the galactic average by a high degree. The findings suggest magnetic fields strongly impact star-forming regions which means they played a part in the creation of our own solar system.
Published Surprise gamma-ray feature beyond our galaxy
(via sciencedaily.com) Original source Astronomers analyzing 13 years of data from NASA's Fermi Gamma-ray Space Telescope have found an unexpected and as yet unexplained feature outside of our galaxy.
Published Artificial muscle device produces force 34 times its weight
(via sciencedaily.com) Original source Scientists developed a soft fluidic switch using an ionic polymer artificial muscle that runs with ultra-low power to lift objects 34 times greater than its weight. Its light weight and small size make it applicable to various industrial fields such as soft electronics, smart textiles, and biomedical devices by controlling fluid flow with high precision, even in narrow spaces.
Published Astronomers make rare exoplanet discovery, and a giant leap in detecting Earth-like bodies
(via sciencedaily.com) Original source Astronomers have made the rare discovery of a small, cold exoplanet and its massive outer companion -- shedding light on the formation of planets like Earth.
