Published Hidden views of vast stellar nurseries



Astronomers have created a vast infrared atlas of five nearby stellar nurseries by piecing together more than one million images. These large mosaics reveal young stars in the making, embedded in thick clouds of dust. Thanks to these observations, astronomers have a unique tool with which to decipher the complex puzzle of stellar birth.
Published Milk reaction inspires new way to make highly conductive gel films



A research team has developed what they call a 'dip-and-peel' strategy for simple and rapid fabrication of two-dimensional ionogel membranes. By dipping sustainable biomass materials in certain solvents, molecules naturally respond by arranging themselves into functional thin films at the edge of the material that can easily be removed using nothing more than a simple set of tweezers.
Published Robotic proxy brings remote users to life in real time



Researchers have developed a robot, called ReMotion, that occupies physical space on a remote user's behalf, automatically mirroring the user's movements in real time and conveying key body language that is lost in standard virtual environments.
Published Measurement of the Universe's expansion rate weighs in on a longstanding debate in physics and astronomy



A team used a first-of-its-kind technique to measure the expansion rate of the Universe, providing insight that could help more accurately determine the Universe's age and help physicists and astronomers better understand the cosmos.
Published Astronomers find no young binary stars near Milky Way's black hole



Scientists analyzed over a decade's worth of data about 16 young supermassive stars orbiting the supermassive black hole at the center of the Milky Way galaxy. Supermassive stars typically are formed in pairs, but the new study found that all 16 of the stars were singletons. The findings support a scenario in which the supermassive black hole drives nearby stars to either merge or be disrupted, with one of the pair being ejected from the system.
Published Researchers measure the light emitted by a sub-Neptune planet's atmosphere



Researchers observed exoplanet GJ 1214b's atmosphere by measuring the heat it emits while orbiting its host star. Astronomers directly detected the light emitted by a sub-Neptune exoplanet -- a category of planets that are larger than Earth but smaller than Neptune.
Published Galactic bubbles are more complex than imagined



Astronomers have revealed new evidence about the properties of the giant bubbles of high-energy gas that extend far above and below the Milky Way galaxy's center.
Published The influence of AI on trust in human interaction



As AI becomes increasingly realistic, our trust in those with whom we communicate may be compromised. Researchers at the University of Gothenburg have examined how advanced AI systems impact our trust in the individuals we interact with.
Published Scurrying centipedes inspire many-legged robots that can traverse difficult landscapes



Intrigued to see if the many limbs could be helpful for locomotion in this world, a team of physicists, engineers, and mathematicians are using this style of movement to their advantage. They developed a new theory of multilegged locomotion and created many-legged robotic models, discovering the robot with redundant legs could move across uneven surfaces without any additional sensing or control technology as the theory predicted.
Published Quantum lidar prototype acquires real-time 3D images while fully submerged underwater



Researchers have demonstrated a prototype lidar system that uses quantum detection technology to acquire 3D images while submerged underwater. The high sensitivity of this system could allow it to capture detailed information even in extremely low-light conditions found underwater.
Published The future of data storage lies in DNA microcapsules



Storing data in DNA sounds like science fiction, yet it lies in the near future. Experts expect the first DNA data center to be up and running within five to ten years. Data won't be stored as zeros and ones in a hard drive but in the base pairs that make up DNA: AT and CG. Such a data center would take the form of a lab, many times smaller than the ones today.
Published Neutron star's X-rays reveal 'photon metamorphosis'



A 'beautiful effect' predicted by quantum electrodynamics (QED) can explain the puzzling first observations of polarized X-rays emitted by a magnetar -- a neutron star featuring a powerful magnetic field, according to an astrophysicist.
Published Hubble follows shadow play around planet-forming disk



The young star TW Hydrae is playing 'shadow puppets' with scientists observing it with NASA's Hubble Space Telescope. In 2017, astronomers reported discovering a shadow sweeping across the face of a vast pancake-shaped gas-and-dust disk surrounding the red dwarf star. The shadow isn't from a planet, but from an inner disk slightly inclined relative to the much larger outer disk -- causing it to cast a shadow. One explanation is that an unseen planet's gravity is pulling dust and gas into the planet's inclined orbit. The young star TW Hydrae is playing 'shadow puppets' with scientists observing it with NASA's Hubble Space Telescope. Now, a second shadow -- playing a game of peek-a-boo -- has emerged in just a few years between observations stored in Hubble's MAST archive. This could be from yet another disk nestled inside the system. The two disks are likely evidence of a pair of planets under construction.
Published Astronomers spot a star swallowing a planet



Scientists have observed a star swallowing a planet for the first time. Earth will meet a similar fate in 5 billion years.
Published Astronomers find distant gas clouds with leftovers of the first stars



Using ESO's Very Large Telescope (VLT), researchers have found for the first time the fingerprints left by the explosion of the first stars in the Universe. They detected three distant gas clouds whose chemical composition matches what we expect from the first stellar explosions. These findings bring us one step closer to understanding the nature of the first stars that formed after the Big Bang.
Published 'Gluing' soft materials without glue



If you're a fan of arts and crafts, you're likely familiar with the messy, sticky, frustration-inducing nature of liquid glues. But researchers now have a brand-new way to weld squishy stuff together without the need for glue at all. They've demonstrated a universal, 'electroadhesion' technique that can adhere soft materials to each other just by running electricity through them.
Published Deep neural network provides robust detection of disease biomarkers in real time



A lab has developed a deep neural network that improves the accuracy of their unique devices for detecting pathogen biomarkers.
Published A stormy, active sun may have kickstarted life on Earth



The first building blocks of life on Earth may have formed thanks to eruptions from our Sun, a new study finds. A series of chemical experiments show how solar particles, colliding with gases in Earth's early atmosphere, can form amino acids and carboxylic acids, the basic building blocks of proteins and organic life.
Published Webb finds water vapor, but from a rocky planet or its star?



Astronomers used NASA's James Webb Space Telescope to study a rocky exoplanet known as GJ 486 b. It is too close to its star to be within the habitable zone, with a surface temperature of about 800 degrees Fahrenheit (430 degrees Celsius). And yet, their observations show hints of water vapor.
Published Astronomers detect 'nearby' black hole devouring a star



Astronomers have discovered a new 'tidal disruption event,' in which the center of a galaxy lights up as its supermassive black hole rips apart a passing star. The outburst is the closest tidal disruption event observed to date, and one of the first to be identified at infrared wavelengths.
