Published Liquid metal sticks to surfaces without a binding agent
(via sciencedaily.com) Original source Everyday materials such as paper and plastic could be transformed into electronic 'smart devices' by using a simple new method to apply liquid metal to surfaces, according to scientists. The study demonstrates a technique for applying a liquid metal coating to surfaces that do not easily bond with liquid metal. The approach is designed to work at a large scale and may have applications in wearable testing platforms, flexible devices, and soft robotics.
Published Using photosynthesis for Martian occupation -- while making space travel more sustainable
(via sciencedaily.com) Original source Researchers are working on sustainable technology to harvest solar power in space -- which could supplement life support systems on the Moon and Mars.
Published Lingering effects of Neanderthal DNA found in modern humans
(via sciencedaily.com) Original source Recent scientific discoveries have shown that Neanderthal genes comprise some 1 to 4% of the genome of present-day humans whose ancestors migrated out of Africa, but the question remained open on how much those genes are still actively influencing human traits -- until now.
Published Breakthrough: Scientists develop artificial molecules that behave like real ones
(via sciencedaily.com) Original source Scientists have developed synthetic molecules that resemble real organic molecules. A collaboration of researcher can now simulate the behavior of real molecules by using artificial molecules.
Published Elusive planets play 'hide and seek' with CHEOPS
(via sciencedaily.com) Original source Astronomers have clearly identified the existence of four new exoplanets. The four mini-Neptunes are smaller and cooler, and more difficult to find than the so-called Hot Jupiter exoplanets which have been found in abundance.
Published Schrödinger's cat makes better qubits
(via sciencedaily.com) Original source Drawing from Schrodinger's cat thought experiment, scientists have built a 'critical cat code' qubit that uses bosons to store and process information in a way that is more reliable and resistant to errors than previous qubit designs.
Published Octopuses rewire their brains to adapt to seasonal temperature shifts
(via sciencedaily.com) Original source Octopuses don't thermoregulate, so their powerful brains are exposed to -- and potentially threatened by -- changes in temperature. Researchers report that two-spot octopuses adapt to seasonal temperature shifts by producing different neural proteins under warm versus cool conditions. The octopuses achieve this by editing their RNA, the messenger molecule between DNA and proteins. This rewiring likely protects their brains, and the researchers suspect that this unusual strategy is used widely amongst octopuses and squid.
Published Long missions, frequent travel take a toll on astronauts' brains
(via sciencedaily.com) Original source A study looking at how the human brain reacts to traveling outside Earth's gravity suggests frequent flyers should wait three years after longer missions to allow the physiological changes in their brains to reset.
Published Chatgpt designs a robot
(via sciencedaily.com) Original source Poems, essays and even books -- is there anything the OpenAI platform ChatGPT can't handle? These new AI developments have inspired researchers to dig a little deeper: For instance, can ChatGPT also design a robot? And is this a good thing for the design process, or are there risks?
Published New dino, 'Iani,' was face of a changing planet
(via sciencedaily.com) Original source A newly discovered plant-eating dinosaur may have been a species' 'last gasp' during a period when Earth's warming climate forced massive changes to global dinosaur populations.
Published What made the brightest cosmic explosion of all time so exceptional?
(via sciencedaily.com) Original source Last year, telescopes around the world registered the brightest cosmic explosion of all time. Astrophysicists can now explain what made it so dazzling.
Published Water molecules define the materials around us
(via sciencedaily.com) Original source A new paper argues that materials like wood, bacteria, and fungi belong to a newly identified class of matter, 'hydration solids.' The new findings emerged from ongoing research into the strange behavior of spores, dormant bacterial cells.
Published New study identifies mechanism driving the sun's fast wind
(via sciencedaily.com) Original source Researchers used data from NASA's Parker Solar Probe to explain how the solar wind is capable of surpassing speeds of 1 million miles per hour. They discovered that the energy released from the magnetic field near the sun's surface is powerful enough to drive the fast solar wind, which is made up of ionized particles -- called plasma -- that flow outward from the sun.
Published To groom or not to groom: 'Triage' in the ant kingdom
(via sciencedaily.com) Original source Social ants are masters of cooperative disease defense. They collectively take care of each other to prevent the spread of infections within a colony. But how does an individual ant know whom it should groom? A multidisciplinary team of researchers combined experimental and theoretical approaches to get a detailed look into ants' sanitary decision-making.
Published When pigeons dream
(via sciencedaily.com) Original source Dreams have been considered a hallmark of human sleep for a long time. Latest findings, however, suggest that when pigeons sleep, they might experience visions of flight. Researchers studied brain activation patterns in sleeping pigeons, using functional magnetic resonance imaging. The study revealed that similar to mammals, most of the brain is highly active during REM sleep. However, this wake-like state might come at a cost of reduced waste removal from the brain.
Published First detection of secondary supermassive black hole in a well-known binary system
(via sciencedaily.com) Original source An international team of astronomers observed the second one of the two supermassive black holes circling each other in an active galaxy OJ 287.
Published Wireless olfactory feedback system to let users smell in the VR world
(via sciencedaily.com) Original source A research team recently invented a novel, wireless, skin-interfaced olfactory feedback system that can release various odours with miniaturized odor generators (OGs). The new technology integrates odors into virtual reality (VR)/augmented reality (AR) to provide a more immersive experience, with broad applications ranging from 4D movie watching and medical treatment to online teaching.
Published Robot 'chef' learns to recreate recipes from watching food videos
(via sciencedaily.com) Original source Researchers have trained a robotic 'chef' to watch and learn from cooking videos, and recreate the dish itself.
Published Researchers demonstrate secure information transfer using spatial correlations in quantum entangled beams of light
(via sciencedaily.com) Original source Researchers have demonstrated the principle of using spatial correlations in quantum entangled beams of light to encode information and enable its secure transmission.
Published Webb Space Telescope detects universe's most distant complex organic molecules
(via sciencedaily.com) Original source Researchers have detected complex organic molecules in a galaxy more than 12 billion light-years away from Earth -- the most distant galaxy in which these molecules are now known to exist. Thanks to the capabilities of the recently launched James Webb Space Telescope and careful analyses from the research team, a new study lends critical insight into the complex chemical interactions that occur in the first galaxies in the early universe.
