Published New method to measure entropy production on the nanoscale



Entropy, the amount of molecular disorder, is produced in several systems but cannot be measured directly. A new equation sheds new light on how entropy is produced on a very short time scale in laser excited materials.
Published Tiniest 'starquake' ever detected



An orange dwarf star has yielded the tiniest 'starquakes' ever recorded, measured by an international team of scientists.
Published Scientists on the hunt for evidence of quantum gravity's existence at the South Pole



An Antarctic large-scale experiment is striving to find out if gravity also exists at the quantum level. An extraordinary particle able to travel undisturbed through space seems to hold the answer.
Published Cool paint coatings help pedestrians feel up to 1.5 degrees Celsius cooler in urban setting



A real-world study has shown that the use of cool paint coatings in cities can help pedestrians feel up to 1.5 degrees Celsius cooler, making the urban area more comfortable for work and play.
Published Astronomers discover 49 new galaxies in under three hours



New work aimed to study the star-forming gas in a single radio galaxy. Although the team didn't find any star-forming gas in the galaxy they were studying, they instead discovered other galaxies while inspecting the data. In total, the gas of 49 galaxies was detected.
Published James Webb Space Telescope captures the end of planet formation



How much time do planets have to form from a swirling disk of gas and dust around a star? A new study gives scientists a better idea of how our own solar system came to be.
Published Signs of life would be detectable in single ice grain emitted from extraterrestrial moons



Could life be found in frozen sea spray from moons orbiting Saturn or Jupiter? New research finds that life can be detected in a single ice grain containing one bacterial cell or portions of a cell. The results suggest that if life similar to that on Earth exists on these planetary bodies, that this life should be detectable by instruments launching in the fall.
Published Secrets of the Van Allen belt revealed in new study



A challenge to space scientists to better understand our hazardous near-Earth space environment has been set in a new study.
Published In-situ observation of nanoscale heat propagation



A research team has developed a technique that enables the nanoscale observation of heat propagation paths and behavior within material specimens. This was achieved using a scanning transmission electron microscope (STEM) capable of emitting a pulsed electron beam and a nanosized thermocouple -- a high-precision temperature measurement device.
Published Icy impacts: Planetary scientists use physics and images of impact craters to gauge the thickness of ice on Europa



New study reveals that Europa's ice shell is at least 20 kilometers thick.
Published Scientists find one of the most ancient stars that formed in another galaxy



The first generation of stars transformed the universe. Inside their cores, simple hydrogen and helium fused into a rainbow of elements. When these stars died, they exploded and sent these new elements across the universe. The iron running in your veins and the calcium in your teeth and the sodium powering your thoughts were all born in the heart of a long-dead star.
Published Quantum tornado provides gateway to understanding black holes



Scientists have created a giant quantum vortex to mimic a black hole in superfluid helium that has allowed them to see in greater detail how analogue black holes behave and interact with their surroundings.
Published Astrophysicist's research could provide a hint in the search for dark matter



Dark matter is one of science's greatest mysteries. Although it is believed to make up about 85 percent of the cosmos, scientists know very little about its fundamental nature. Research provides some of the most stringent constraints on the nature of dark matter yet. It also revealed a small hint of a signal that, if real, could be confirmed in the next decade or so.
Published Bendable energy storage materials by cool science



Imaging being able to wear clothes that charge your gadgets just by wearing them. New research has brought us a step closer to achieving this reality.
Published Using light to produce medication and plastics more efficiently



Anyone who wants to produce medication, plastics or fertilizer using conventional methods needs heat for chemical reactions -- but not so with photochemistry, where light provides the energy. The process to achieve the desired product also often takes fewer intermediate steps. Researchers are now going one step further and are demonstrating how the energy efficiency of photochemical reactions can be increased tenfold. More sustainable and cost-effective applications are now tantalizingly close.
Published Advance for soft robotics manufacturing, design



Engineers propose a new quantitative framework to account for and predict the impact of temperature on the curing speed of platinum-catalyzed silicone elastomers. The findings could maximize throughput and minimize waste in the manufacturing of components for soft robotics and wearables.
Published Revolutionary method developed for mass-producing polymer solid electrolytes



Scientists have unveiled a groundbreaking technique for mass-producing polymer solid electrolytes, crucial components in batteries.
Published New research suggests that our universe has no dark matter



A new study challenges the current model of the universe by showing that, in fact, it has no room for dark matter.
Published Protein fragments ID two new 'extremophile' microbes--and may help find alien life



Perfectly adapted microorganisms live in extreme environments from deep-sea trenches to mountaintops. Learning more about how these extremophiles survive in hostile conditions could inform scientists about life on Earth and potential life on other planets.
Published Supply chain disruptions will further exacerbate economic losses from climate change



Global GDP loss from climate change will increase exponentially the warmer the planet gets when its cascading impact on global supply chains is factored in, finds a new study.
