Published Flicker from the dark: Reading between the lines to model our galaxy's central black hole
(via sciencedaily.com) Researchers have shown in a single model the full story of how gas travels in the center of the Milky Way -- from being blown off by stars to falling into the black hole.
Published Optical microphone sees sound like never before
(via sciencedaily.com) A camera system can see sound vibrations with such precision and detail that it can reconstruct the music of a single instrument in a band or orchestra. Even the most high-powered and directed microphones can't eliminate nearby sounds, ambient noise and the effect of acoustics when they capture audio. The novel system uses two cameras and a laser to sense high-speed, low-amplitude surface vibrations. These vibrations can be used to reconstruct sound, capturing isolated audio without inference or a microphone.
Published Scientists map sulfur residue on Jupiter's icy moon Europa
(via sciencedaily.com) A team has used the Hubble Space Telescope to observe Jupiter's moon, Europa, at ultraviolet wavelengths, filling in a 'gap' in the various wavelengths used to observe this icy water world. The team's near-global UV maps show concentrations of sulfur dioxide on Europa's trailing side.
Published Sniffing out your identity with breath biometrics
(via sciencedaily.com) Researchers have developed an artificial 'nose' that can identify individuals from their breath. Built with a 16-channel sensor array that can detect different compounds found in a person's breath, the olfactory sensor system has the potential to become another option in the biometric security toolkit. Combined with machine learning, the 'artificial nose' was able to authenticate up to 20 individuals with an average accuracy of more than 97%.
Published Modern wind turbines can more than compensate for decline in global wind resource
(via sciencedaily.com) Wind energy contributes significantly to the energy sector's sustainable, low-CO2 transformation. However, the efficiency of wind turbines depends on available wind resources and the technical characteristics of the turbines.
Published 1,700-year-old Korean genomes show genetic heterogeneity in Three Kingdoms period Gaya
(via sciencedaily.com) Scientists have successfully sequenced and studied the whole genome of eight 1,700-year-old individuals dated to the Three Kingdoms period of Korea (approx. 57 BC-668 AD). The first published genomes from this period in Korea and bring key information for the understanding of Korean population history.
Published Scientists identify a possible source for Charon's red cap
(via sciencedaily.com) Scientists combined data from NASA's New Horizons mission with novel laboratory experiments and exospheric modeling to reveal the likely composition of the red cap on Pluto's moon Charon and how it may have formed. This first-ever description of Charon's dynamic methane atmosphere using new experimental data provides a fascinating glimpse into the origins of this moon's red spot as described in two recent articles.
Published How elliptical craters could shed light on age of Saturn's moons
(via sciencedaily.com) A new study describes how unique populations of craters on two of Saturn's moons could help indicate the satellites' age and the conditions of their formation. Using data from NASA's Cassini mission, researchers have surveyed elliptical craters on Saturn's moons Tethys and Dione for this study.
Published Sensor imperfections are perfect for forensic camera analysis
(via sciencedaily.com) In a project aimed at developing intelligent tools to fight child exploitation, computer scientists have developed a system to analyze the noise produced by individual cameras. This information can be used to link a video or an image to a particular camera.
Published A blueprint for life forms on Mars?
(via sciencedaily.com) Microbes taken from surface sediment near Lost Hammer Spring, Canada, about 900 km south of the North Pole, could provide a blueprint for the kind of life forms that may once have existed, or may still exist, on Mars.
Published Melting Arctic ice could transform international shipping routes, study finds
(via sciencedaily.com) Melting ice in the Arctic Ocean could yield new trade routes in international waters, reducing the shipping industry's carbon footprint and weakening Russia's control over trade routes through the Arctic, a study found.
Published More digging needed to see whether bones of fallen Waterloo soldiers were sold as fertilizer, as few human remains have ever been found
(via sciencedaily.com) Launched on the anniversary of the conflict, a new study suggests that mystery still surrounds what happened to the bodies of Waterloo militaries.
Published Gaia space telescope rocks the science of asteroids
(via sciencedaily.com) The European Gaia space mission has produced an unprecedented amount of new, improved, and detailed data for almost two billion objects in the Milky Way galaxy and the surrounding cosmos. The Gaia Data Release 3 on Monday revolutionizes our knowledge of the Solar System and the Milky Way and its satellite galaxies.
Published Mangrove and reef restoration yield positive returns on investment for flood protection, study shows
(via sciencedaily.com) Restoration of mangroves and coral reefs can be a cost-effective solution for coastal flood reduction in more than 20 countries across the Caribbean. Researchers used methods from the risk and insurance industry to provide rigorous valuations of these natural defenses and show that they can deliver a positive return on investment, with the benefits from reduced flood damage exceeding the costs of restoration. The results point toward new opportunities to support restoration efforts with funds from sources that support hazard mitigation, climate adaptation, and disaster recovery, including FEMA.
Published Math model predicts efficacy of drug treatments for heart attacks
(via sciencedaily.com) Researchers used mice to develop a mathematical model of a myocardial infarction. The new model predicts several useful new drug combinations that may one day help treat heart attacks, according to researchers.
Published Are new corals in Sydney dangerous invaders or harmless refugees?
(via sciencedaily.com) A new study has found that invading subtropical corals will survive and thrive in coastal Sydney, which could spell trouble for existing Sydney coral species.
Published Training virtually can reduce psychosocial stress and anxiety
(via sciencedaily.com) Everyone knows that exercise brings physical and psychological benefits. A new study suggests that virtual reality exercise induces similar effects, meaning those with limited mobility may be able to improve their mental well-being.
Published Newly documented population of polar bears in Southeast Greenland sheds light on the species' future in a warming Arctic
(via sciencedaily.com) A new population of polar bears documented on the southeast coast of Greenland use glacier ice to survive despite limited access to sea ice. This small, genetically distinct group of polar bears could be important to the future of the species in a warming world.
Published Humans responsible for over 90% of world's oil slicks
(via sciencedaily.com) Scientists mapping oil pollution across the Earth's oceans have found that more than 90% of chronic oil slicks come from human sources, a much higher proportion than previously estimated.
Published Martian meteorite upsets planet formation theory
(via sciencedaily.com) A new study of an old meteorite contradicts current thinking about how rocky planets like the Earth and Mars acquire volatile elements such as hydrogen, carbon, oxygen, nitrogen and noble gases as they form.
