Published World's largest hummingbird is actually two species
(via sciencedaily.com) Original source The Giant Hummingbird of western South America is not one species but two, according to an international group of researchers. The northern population stays in the high Andes year-round while the southern population migrates from sea level up to 14,000 feet for the nonbreeding months.
Published Fruit fly testes offer potential tool against harmful insects
(via sciencedaily.com) Original source A way to curb nagging insects has been flying under our radar -- an enzyme from fruit fly testes. The compound could control bugs that carry disease and harm crops by stunting their ability to procreate, researchers have found.
Published Like dad and like mum ... all in one plant
(via sciencedaily.com) Original source Scientists have established a system to generate clonal sex cells in tomato plants and used them to design the genomes of offspring. The fertilization of a clonal egg from one parent by a clonal sperm from another parent led to plants containing the complete genetic information of both parents.
Published Nature's 3D printer: Bristle worms form bristles piece by piece
(via sciencedaily.com) Original source Molecular biologists provide exciting insights into the bristles of the marine annelid worm Platynereis dumerilii. Specialized cells, so-called chaetoblasts, control the formation of the bristles. Their mode of operation is astonishingly similar to that of a technical 3D printer.
Published ONe novae stellar explosion may be source of our phosphorus
(via sciencedaily.com) Original source Astronomers have proposed a new theory to explain the origin of phosphorus, one of the elements important for life on Earth. The theory suggests a type of stellar explosion known as ONe novae as a major source of phosphorus.
Published Squeezed by neighbors, planet glows with molten lava
(via sciencedaily.com) Original source Astrophysicists discovered that an exoplanet is covered with so many active volcanoes that seen from a distance it would take on a fiery, glowing-red hue.
Published Astrophysicists discover a novel method for hunting the first stars
(via sciencedaily.com) Original source A recent study has discovered a novel method for detecting the first-generations stars, known as Population III (Pop III) stars, which have never been directly detected. These potential discoveries about Pop III stars hold the promise of unlocking the secrets of the universe's origin and providing a deeper understanding of the remarkable journey from the primordial cosmos to the world we inhabit today.
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 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 Did a magnetic field collapse trigger the emergence of animals?
(via sciencedaily.com) Original source Researchers uncovered compelling evidence that Earth's magnetic field was in a highly unusual state when the macroscopic animals of the Ediacaran Period -- 635 to 541 million years ago -- diversified and thrived. Their study raises the question of whether these fluctuations in Earth's ancient magnetic field led to shifts in oxygen levels that may have been crucial to the proliferation of life forms millions of years ago.
Published Wild orangutan treats wound with pain-relieving plant
(via sciencedaily.com) Original source A wild orangutan was observed applying a plant with known medicinal properties to a wound, a first for a wild animal.
Published Webb telescope probably didn't find life on an exoplanet -- yet
(via sciencedaily.com) Original source Recent reports of NASA's James Webb Space Telescope finding signs of life on a distant planet understandably sparked excitement. A new study challenges this finding, but also outlines how the telescope might verify the presence of the life-produced gas.
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 Marriage of synthetic biology and 3D printing produces programmable living materials
(via sciencedaily.com) Original source Scientists are harnessing cells to make new types of materials that can grow, repair themselves and even respond to their environment. These solid 'engineered living materials' are made by embedding cells in an inanimate matrix that's formed in a desired shape. Now, researchers have 3D printed a bioink containing plant cells that were then genetically modified, producing programmable materials. Applications could someday include biomanufacturing and sustainable construction.
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 Researchers parse oddity of distantly related bats in Solomon Islands that appear identical
(via sciencedaily.com) Original source A study of body size in leaf-nosed bats of the Solomon Islands has revealed surprising genetic diversity among nearly indistinguishable species on different islands.
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 Trotting robots reveal emergence of animal gait transitions
(via sciencedaily.com) Original source A four-legged robot trained with machine learning has learned to avoid falls by spontaneously switching between walking, trotting, and pronking -- a milestone for roboticists as well as biologists interested in animal locomotion.
