Published Hearing better with skin than ears
(via sciencedaily.com) A research team develops a sound-sensing skin-attachable acoustic sensor. The new sensor decreased in size and increased in flexibility and is applicable as auditory electronic skin.
Published Bacteria for blastoff: Using microbes to make supercharged new rocket fuel
(via sciencedaily.com) Biofuel scientists used an oddball molecule made by bacteria to develop a new class of sustainable biofuels powerful enough to launch rockets. The candidate molecules have greater projected energy density than any petroleum product, including the leading aviation and rocket fuels, JetA and RP-1.
Published Gemini North spies ultra-faint fossil galaxy discovered on outskirts of Andromeda
(via sciencedaily.com) An unusual ultra-faint dwarf galaxy has been discovered on the outer fringes of the Andromeda Galaxy thanks to the sharp eyes of an amateur astronomer. Follow-up by professional astronomers revealed that the dwarf galaxy -- Pegasus V -- contains very few heavier elements and is likely to be a fossil of the first galaxies.
Published California's Dixie Fire shows impact of legacy effects, prescribed burns
(via sciencedaily.com) The 2021 Dixie Fire burned over nearly 1 million acres in California and cost $637 million to suppress, making it the largest and most expensive wildfire to contain in state history. Fire history largely determined how severely the wildfire burned, and low-severity fire treatments had the largest impact on reducing the worst effects of the fire, according to a research team.
Published New genetic research on remote Pacific islands yields surprising findings on world's earliest seafarers
(via sciencedaily.com) New genetic research from remote islands in the Pacific offers fresh insights into the ancestry and culture of the world's earliest seafarers, including family structure, social customs, and the ancestral populations of the people living there today.
Published Virtual reality technology could strengthen effects of traditional rehabilitation for multiple sclerosis
(via sciencedaily.com) By increasing sensory input and promoting multisensory processing, virtual reality may increase the effectiveness of traditional cognitive rehabilitation and exercise training in individuals with MS, according to researchers.
Published Floating in space might be fun, but study shows it's hard on earthly bodies
(via sciencedaily.com) Bone loss happens in humans -- as we age, get injured, or any scenario where we can't move the body, we lose bone. Understanding what happens to astronauts and how they recover is incredibly rare. It lets us look at the processes happening in the body in such a short time frame. We would have to follow someone for decades on Earth to see the same amount of bone loss.
Published Study reveals an unprecedented change in Europe's fire regime
(via sciencedaily.com) A study reveals an unprecedented change in the fire regime in Europe which is related to climate change. The affected areas are in Southern, Central and Northern Europe but this historical change in Europe's fire regime is more intense in the Mediterranean area.
Published Tonga volcano eruption among the most powerful ever observed, triggering atmospheric gravity waves that reached the edge of space
(via sciencedaily.com) The eruption of the Hunga Tonga-Hunga Ha'apai submarine volcano in January 2022 was one of the most explosive volcanic events of the modern era, a new study has confirmed.
Published Climate change will increase chances of wildfire globally -- but humans can still help reduce the risk
(via sciencedaily.com) New research highlights how the risk of wildfire is rising globally due to climate change -- but also, how human actions and policies can play a critical role in regulating regional impacts. The study shows that anthropogenic climate change is a 'push' factor that enhances the risk of wildfires globally.
Published Wildfires may have sparked ecosystem collapse during Earth's worst mass extinction
(via sciencedaily.com) New research reveals that wildfires may have been a key contributor to the total collapse of land ecosystems during Earth's worst mass extinction event over 250 million years ago.
Published Laser creates a miniature magnetosphere
(via sciencedaily.com) A research team realized magnetic reconnection driven by electron dynamics in laser-produced plasmas and measured the pure electron outflows. Their findings will be applied not only to space and astrophysical plasmas, but also to magnetic propulsion and fusion plasmas.
Published 'Fake' data helps robots learn the ropes faster
(via sciencedaily.com) In a step toward robots that can learn on the fly like humans do, a new approach expands training data sets for robots that work with soft objects like ropes and fabrics, or in cluttered environments.
Published 'Quake brain' effects suffered by resilient Cantabrians fade over time
(via sciencedaily.com) New research suggests the brain function of otherwise-healthy individuals exposed to event trauma has the ability to 'bounce back' over time once the threat resolves. Researchers conducted a follow-up study on a group of Cantabrians, who had been exposed to trauma during the region's earthquakes over a decade ago.
Published Asteroids: Researchers simulate defense of Earth
(via sciencedaily.com) NASA's Double Asteroid Redirection Test (DART) mission is the world's first full-scale planetary defense test against potential asteroid impacts on Earth. Researchers now show that instead of leaving behind a relatively small crater, the impact of the DART spacecraft on its target could leave the asteroid near unrecognizable.
Published Underwater jars reveal Roman period winemaking practices
(via sciencedaily.com) Winemaking practices in coastal Italy during the Roman period involved using native grapes for making wine in jars waterproofed with imported tar pitch, according to a new study.
Published Thawing permafrost is shaping the global climate
(via sciencedaily.com) How is climate change affecting the permanently frozen soils of the Arctic? What will the consequences be for the global climate, human beings, and ecosystems? And what can be done to stop it?
Published Iceland volcano eruption opens a rare window into the Earth beneath our feet
(via sciencedaily.com) The recent Fagradalsfjall eruption in the southwest of Iceland has enthralled the whole world, including nature lovers and scientists alike. The eruption was especially important as it provided geologists with a unique opportunity to study magmas that were accumulated in a deep crustal magma reservoir but ultimately derived from the Earth's mantle (below 20 km).
Published Ice Age wolf DNA reveals dogs trace ancestry to two separate wolf populations
(via sciencedaily.com) An international group of geneticists and archaeologists have found that the ancestry of dogs can be traced to at least two populations of ancient wolves. The work moves us a step closer to uncovering the mystery of where dogs underwent domestication, one of the biggest unanswered questions about human prehistory.
Published Falling stardust, wobbly jets explain blinking gamma ray bursts
(via sciencedaily.com) Astrophysicists have developed the first 3D simulation of the entire evolution of a jet -- from its birth by a rotating black hole to its emission far from the collapsing star. Simulation shows that as the star collapses, its material falls on the disk that swirls around the black hole. This falling material tilts the disk, and, in turn, tilts the jet, which wobbles as it struggles to return to its original trajectory. The wobbling jet explains the longstanding mystery of why gamma ray bursts blink and shows that these bursts are even rarer than previously thought.
