Published Delaying methane mitigation increases risk of breaching Paris Agreement climate goal, study finds
(via sciencedaily.com) Original source A new study shows that efforts to reduce methane emissions are needed immediately if we are to meet global climate change goals. A key element of the 2015 Paris Agreement, a legally binding international treaty on climate change, is the commitment to limit average global temperatures increases to well below 2°C above pre-industrial levels, and pursue efforts to limit global warming to 1.5°C above pre-industrial levels. This requires reaching net-zero CO2 emissions by or around 2050 -- and deep reductions in methane and other emissions.
Published Astronomers reveal new features of galactic black holes
(via sciencedaily.com) An international team of scientists, including astrophysicists, report on a dedicated observational campaign on the Galactic microquasar dubbed GRS 1915+105. The team revealed features of a microquasar system that have never before been seen. Using the massive Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China, astronomers discovered a quasi-periodic oscillation (QPO) signal in the radio band for the first time from any microquasar systems.
Published Lifespan of aging science's model organism driven by reproductive self-destruction
(via sciencedaily.com) Original source The lifespan of a small roundworm that has been used as a key model organism in aging research is limited by how it self-sacrifices to feed its young, finds a new study.
Published Insect protein slows weight gain, boosts health status in obese mice
(via sciencedaily.com) Original source A new study in mice suggests replacing traditional protein sources with mealworms in high-fat diets could slow weight gain, improve immune response, reduce inflammation, enhance energy metabolism, and beneficially alter the ratio of good to bad cholesterol.
Published Global wildlife trade risks altering evolutionary history and ecosystem function, study suggests
(via sciencedaily.com) Original source Some of the world's most distinct and ancient animal species, which play crucial roles in our planet's ecosystems, are exploited for the wildlife trade across large parts of the world, according to new research.
Published Genetic study reveals that a captive-bred population could save endangered crocodile from extinction
(via sciencedaily.com) Original source Performing a genetic evaluation on the largest captive-bred population of the critically endangered Orinoco crocodile, researchers have revealed that the population preserves much of its founder diversity and no inbreeding, making it suitable for implementing wild releases. Since this species is almost extinct in the wild, the news brings hope for the recovery of populations.
Published A quick look inside a human being
(via sciencedaily.com) Original source Physicists have succeeded in making a new imaging technique ready for use on humans. Radioactive markers and radiation are not necessary for this.
Published How eavesdropping viruses battle it out to infect us
(via sciencedaily.com) Original source Dozens of viruses -- at least -- can eavesdrop on host information. Not only did they demonstrate the strategy's abundance, but they also discovered tools that control it and send signals that tell bacteriophage viruses to flip from chill (lysogeny) into kill (lysis) mode. They showed that in polylysogeny, phages can coexist, their viral DNA or RNA hidden tucked inside the bacterium's own, replicating right along with the cells. But the infiltrating phages aren't exactly peaceful; it's more like mutually assured destruction. And the tenuous detente lasts only until something triggers one or more of the phages to switch into kill mode.
Published Earlier and earlier high-Arctic spring replaced by 'extreme year-to-year variation'
(via sciencedaily.com) Original source About 15 years ago, researchers reported that the timing of spring in high-Arctic Greenland had advanced at some of the fastest rates of change ever seen anywhere in the world. But, according to new evidence, that earlier pattern has since been completely erased. Instead of coming earlier and earlier, it seems the timing of Arctic spring is now driven by tremendous climate variability with drastic differences from one year to the next.
Published Family trees from the European Neolithic
(via sciencedaily.com) Original source The Neolithic burial site of Gurgy 'les Noisats' in France revealed two unprecedentedly large family trees which allowed a Franco-German team to explore the social organization of the 6,700-year-old community. Based on multiple lines of evidence, the team describes a close kin group which practiced monogamy and female exogamy, and experienced generally stable times.
Published New findings offer potential breakthrough in HIV cure research
(via sciencedaily.com) Original source The results of a novel study has revealed exciting findings in the pursuit of an HIV cure.
Published Robotic hand rotates objects using touch, not vision
(via sciencedaily.com) Inspired by the effortless way humans handle objects without seeing them, engineers have developed a new approach that enables a robotic hand to rotate objects solely through touch, without relying on vision.
Published Dark energy camera captures galaxies in lopsided tug of war, a prelude to merger
(via sciencedaily.com) The spiral galaxy NGC 1532, also known as Haley's Coronet, is caught in a lopsided tug of war with its smaller neighbor, the dwarf galaxy NGC 1531.
Published A novel approach for balancing properties in composite materials
(via sciencedaily.com) Scientists are developing an approach to enhance multifunctionality and structural properties simultaneously by embedding patterned nanostructures in composite materials, which could result in more efficient energy systems enhancing everyday life.
Published Dune restoration could increase the resilience of Southern California's urban beaches to sea level rise
(via sciencedaily.com) Original source Over the last several years, the residents of Santa Monica, a coastal city on the edge of Los Angeles, saw something neither they, their parents, or perhaps even their grandparents had ever seen before: a three-foot-tall dune system rising gently from the flat, groomed expanse of one of the world's most famous urban beaches. It's a six year alliance between sand, wind and vegetation, and, according to researchers, it's one way to enlist nature to help protect the coast from the impacts of climate change.
Published Egg 'signatures' will allow drongos to identify cuckoo 'forgeries' almost every time, study finds
(via sciencedaily.com) Original source Egg 'signatures' will allow drongos to identify cuckoo 'forgeries' almost every time, study finds. African cuckoos may have met their match with the fork-tailed drongo, which scientists predict can detect and reject cuckoo eggs from their nest on almost every occasion, despite them on average looking almost identical to drongo eggs.
Published Arctic terns may navigate climate dangers
(via sciencedaily.com) Original source Arctic terns -- which fly on the longest migrations of any animal on Earth -- may be able to navigate the dangers posed by climate change, new research suggests.
Published Discovery of key genetic sequence essential for plant reproduction
(via sciencedaily.com) Original source Researchers have identified a genetic sequence that is essential for plant reproduction. As this region is found in all plant species, it is expected to contribute to future crossbreeding initiatives and help solve the important problem of seed formation defects.
Published Western science catches up with First Nations' medicinal use of ant honey
(via sciencedaily.com) Original source Scientists have discovered the honey produced by Australian ants possesses unique anti-microbial activity against bacteria and fungi that could make the liquid useful medicinally.
Published New archosaur species shows that precursor of dinosaurs and pterosaurs was armored
(via sciencedaily.com) Original source Researchers have described a new species of armored reptile that lived near the time of the first appearance of dinosaurs. With bony plates on its backbone, this archosaur fossil reveals that armor was a boomerang trait in the story of dinosaur and pterosaur evolution: the group's ancestors were armored, but this characteristic was lost and then independently re-evolved multiple times later among specialized dinosaurs like ankylosaurs, stegosaurs, and others.
