Published A new amplifying technique for weak and noisy signals
(via sciencedaily.com) Scientists have demonstrated a technique for the recovery of weak, noise-dominated optical signals.
Published The power of chaos: A robust and low-cost cryptosystem for the post-quantum era
(via sciencedaily.com) Scientists develop a chaos-based stream cipher that can withstand attacks from large-scale quantum computers.
Published How fuel poverty 'gets under the skin'
(via sciencedaily.com) Original source New research shows that fuel poverty makes people's physical and mental health worse. Researchers found that not being able to keep homes warm enough affects people's levels of life satisfaction. But they also found that it impacts people's physical health by causing higher levels of inflammation, measured by fibrinogen, a blood-based biomarker.
Published New computational tool predicts cell fates and genetic perturbations
(via sciencedaily.com) Researchers have built a machine learning framework that can define the mathematical equations describing a cell's trajectory from one state to another, such as its development from a stem cell into one of several different types of mature cell. The framework, called dynamo, can also be used to figure out the underlying mechanisms -- the specific cocktail of gene activity -- driving changes in the cell.
Published What the rise of oxygen on early Earth tells us about life on other planets
(via sciencedaily.com) When did the Earth reach oxygen levels sufficient to support animal life? Researchers have discovered that a rise in oxygen levels occurred in step with the evolution and expansion of complex, eukaryotic ecosystems. Their findings represent the strongest evidence to date that extremely low oxygen levels exerted an important limitation on evolution for billions of years.
Published Pioneering research forecasts climate change set to send costs of flooding soaring
(via sciencedaily.com) Climate change could result in the financial toll of flooding rising by more than a quarter in the United States by 2050 -- and disadvantaged communities will bear the biggest brunt, according to new research.
Published Low volcanic temperature ushered in global cooling and the thriving of dinosaurs
(via sciencedaily.com) Dinosaurs came to flourish during the Jurassic period after a volcanic eruption roughly 201 millions years ago wiped out many marine and land animals, leaving them able to evolve and grow. Now, further details about this eruption and the mass extinction have been revealed. A group of researchers demonstrated how low temperature magma slowly heated sedimentary rocks, causing high sulfur dioxide and low carbon dioxide emissions, a process which cooled the earth.
Published Extreme exoplanet has a complex and exotic atmosphere
(via sciencedaily.com) An international team analyzed the atmosphere of one of the most extreme known planets in great detail. The results from this hot, Jupiter-like planet that was first characterized with the help of the CHEOPS space telescope, may help astronomers understand the complexities of many other exoplanets -- including Earth-like planets.
Published New study improves understanding of Southern California’s intense winter rains
(via sciencedaily.com) New research looks to improve prediction of brief but intense rainstorms that can cause devastating flash floods and landslides. Intense rain associated with narrow cold-frontal rainbands may last only a few minutes at a particular location, yet the rain can cause catastrophic flash flooding, debris flows and landslides, and can occur along with tornadoes and severe thunderstorms.
Published Scientists explain mysterious finger-like features in solar flares
(via sciencedaily.com) Astronomers have presented a new explanation for the mysterious downward-moving dark voids seen in some solar flares.
Published Ancient ice reveals mysterious solar storm
(via sciencedaily.com) Through analysis of ice cores from Greenland and Antarctica, a research team has found evidence of an extreme solar storm that occurred about 9,200 years ago. What puzzles the researchers is that the storm took place during one of the sun's more quiet phases -- during which it is generally believed our planet is less exposed to such events.
Published Liquid water beneath Martian south polar cap?
(via sciencedaily.com) Scientists measured the properties of ice-brine mixtures as cold as -145 degrees Fahrenheit to help confirm that salty water likely exists between grains of ice or sediment under the ice cap at Mars' south pole. Laboratory measurements support oddly bright reflections detected by the MARSIS subsurface sounding radar aboard ESA's Mars Express orbiter.
Published How big does your quantum computer need to be?
(via sciencedaily.com) Researchers decided to explore two very different quantum problems: breaking the encryption of Bitcoin and simulating the molecule responsible for biological nitrogen fixation. They describe a tool they created to determine how big a quantum computer needs to be to solve problems like these and how long it will take.
Published Ultrasound technique predicts hip dysplasia in infants
(via sciencedaily.com) A technique that uses ultrasound images to determine the depth and shape of the hip socket can accurately predict which infants with hip dysplasia will develop normal hip structure and which remain dysplastic, according to a new study. Researchers said statistical shape modeling improves on existing techniques and could spare many infants from unnecessary treatment.
Published New control technique uses solar panels to reach desired Mars orbit
(via sciencedaily.com) Aerospace engineers have developed a way to use articulated solar panels to steer the satellite during aerobraking, reducing the number of passes needed, resulting in potential savings in propellant, time, and money.
Published Hope for present-day Martian groundwater dries up in new study
(via sciencedaily.com) Liquid water previously detected under Mars' ice-covered south pole is probably just a dusty mirage, according to a new study of the Red Planet. The finding challenges a 2018 study that appeared to find liquid water under Mars' south polar cap.
Published Consistent asteroid showers rock previous thinking on Mars craters
(via sciencedaily.com) New research has confirmed the frequency of asteroid collisions that formed impact craters on Mars has been consistent over the past 600 million years.
Published Is Vesuvius taking an extended siesta?
(via sciencedaily.com) Located near Naples, Italy, Vesuvius last had a violent eruption in 1944, towards the end of the Second World War. It could be a few hundred years before another dangerous, explosive eruption occurs, suggests a new study by volcano experts.
Published Worldwide coordinated search for dark matter
(via sciencedaily.com) An international team of researchers has published comprehensive data on the search for dark matter using a worldwide network of optical magnetometers. According to the scientists, dark matter fields should produce a characteristic signal pattern that can be detected by correlated measurements at multiple stations of the GNOME network.
Published Mount Etna’s exceptional CO2 emissions are triggered by deep carbon dioxide reservoirs
(via sciencedaily.com) Magma transports carbon dioxide stored in the Earth's mantle to volcanoes, where it is released into the atmosphere. A research team now presents results obtained using a new methodology to clarify the contribution of volcanoes to natural CO2 emissions.
