Published Human activity is making it harder for scientists to interpret oceans' past
(via sciencedaily.com) Original source New research shows human activity is significantly altering the ways in which marine organisms are preserved, with lasting effects that can both improve and impair the fossil record.
Published Possible atmosphere surrounding rocky exoplanet
(via sciencedaily.com) Original source Researchers may have detected atmospheric gases surrounding 55 Cancri e, a hot rocky exoplanet 41 light-years from Earth. This is the best evidence to date for the existence of any rocky planet atmosphere outside our solar system.
Published Iron fingerprints in nearby active galaxy
(via sciencedaily.com) Original source After starting science operations in February, Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) studied the monster black hole at the center of galaxy NGC 4151.
Published Marine bacteria team up to produce a vital vitamin
(via sciencedaily.com) Original source Two species of marine bacteria from the North Sea have established an unusual and sometimes destructive relationship to produce the important vitamin B12. The team's experiments show that the two microbial species have developed a coordinated strategy to obtain the scarce but essential vitamin.
Published Venus has almost no water: A new study may reveal why
(via sciencedaily.com) Original source Billions of years ago, Venus may have harbored as much water as Earth. Today, almost all of it has disappeared. A new study may help to explain why.
Published DDT pollutants found in deep sea fish off Los Angeles coast
(via sciencedaily.com) Original source As the region reckons with its toxic history of offshore dumping off the California coast, new findings raise troubling questions about whether the banned pesticide remains a threat to wildlife and human health.
Published Astronomers observe elusive stellar light surrounding ancient quasars
(via sciencedaily.com) Original source Astronomers observed the elusive starlight surrounding some of the earliest quasars in the universe. The findings may shed light on how the earliest supermassive black holes became so massive despite having a relatively short amount of cosmic time in which to grow.
Published Hubble views a galaxy with a voracious black hole
(via sciencedaily.com) Original source Bright, starry spiral arms surround an active galactic center in a new NASA Hubble Space Telescope image of the galaxy NGC 4951. Located in the Virgo constellation, NGC 4951 is located roughly 50 million light-years away from Earth. It's classified as a Seyfert galaxy, which means that it's an extremely energetic type of galaxy with an active galactic nucleus (AGN).
Published Stony coral tissue loss disease is shifting the ecological balance of Caribbean reefs
(via sciencedaily.com) Original source A new study shows stony coral tissue loss disease is causing drastic changes in the Caribbean's population of corals, which is sure to disrupt the delicate balance of the ecosystem and threaten marine biodiversity and coastal economies.
Published For microscopic organisms, ocean currents act as 'expressway' to deeper depths
(via sciencedaily.com) Original source Some of the ocean's tiniest organisms get swept into underwater currents that act as a conduit that shuttles them from the sunny surface to deeper, darker depths where they play a huge role in affecting the ocean's chemistry and ecosystem, according to new research.
Published Human activity is causing toxic thallium to enter the Baltic sea, according to new study
(via sciencedaily.com) Original source Human activities account for 20% to more than 60% of toxic thallium entering the Baltic Sea over the past eight decades, according to new research. Currently, the amount of thallium, which is considered the most toxic metal for mammals, remains low in Baltic seawater. Much of the thallium in the Baltic, which is the largest human-induced hypoxic area on Earth, has been accumulated in the sediment thanks to sulfide minerals.
Published A 'cosmic glitch' in gravity
(via sciencedaily.com) Original source Researchers have discovered a potential 'cosmic glitch' in the universe's gravity, explaining its strange behavior on a cosmic scale.
Published Webb captures top of iconic horsehead nebula in unprecedented detail
(via sciencedaily.com) Original source NASA's James Webb Space Telescope has captured the sharpest infrared images to date of a zoomed-in portion of one of the most distinctive objects in our skies, the Horsehead Nebula. These observations show the top of the 'horse's mane' or edge of this iconic nebula in a whole new light, capturing the region's complexity with unprecedented spatial resolution.
Published NASA's Webb maps weather on planet 280 light-years away
(via sciencedaily.com) Original source Researchers have successfully used NASA's James Webb Space Telescope to map the weather on the hot gas-giant exoplanet WASP-43 b.
Published Astronomers' simulations support dark matter theory
(via sciencedaily.com) Original source Computer simulations by astronomers support the idea that dark matter -- matter that no one has yet directly detected but which many physicists think must be there to explain several aspects of the observable universe -- exists, according to the researchers.
Published Gemini south reveals origin of unexpected differences in giant binary stars
(via sciencedaily.com) Original source Astronomers have confirmed that differences in binary stars' composition can originate from chemical variations in the cloud of stellar material from which they formed. The results help explain why stars born from the same molecular cloud can possess different chemical composition and host different planetary systems, as well as pose challenges to current stellar and planet formation models.
Published Fixin' to be flexitarian: Scrap fish and invasive species can liven up vegetables
(via sciencedaily.com) Original source Greening the way we eat needn't mean going vegetarian. A healthy, more realistic solution is to adopt a flexitarian diet where seafoods add umami to 'boring' vegetables. A gastrophysicist puts mathematical equations to work in calculating the umami potential of everything from seaweed and shrimp paste to mussels and mackerel.
Published Florida dolphin found with highly pathogenic avian flu
(via sciencedaily.com) Original source Report details first-ever finding of highly pathogenic avian influenza virus in North American dolphin.
Published Could fishponds help with Hawaii's food sustainability?
(via sciencedaily.com) Original source Indigenous aquaculture systems in Hawaii, known as loko i'a or fishponds, can increase the amount of fish and fisheries harvested both inside and outside of the pond. Today, aquaculture supplies less than 1% of Hawaii's 70 million pounds of locally available seafood, but revitalization of loko i'a has the potential to significantly increase locally available seafood.
Published Researchers advance detection of gravitational waves to study collisions of neutron stars and black holes
(via sciencedaily.com) Original source Researchers co-led a study that will improve the detection of gravitational waves--ripples in space and time.
