Published Scientists find evidence of sea star species hybridization


A new study presents genomic evidence of hybridization between two closely related species of sea stars -- Asterias rubens, the common starfish, and Asterias forbesi, known as Forbes' sea star.
Published Study hints at the existence of the closest black holes to Earth in the Hyades star cluster


A new article hints at the existence of several black holes in the Hyades cluster -- the closest open cluster to our solar system -- which would make them the closest black holes to Earth ever detected.
Published Invasive alien species play key role in 60% of global plant and animal extinctions


A new report presents major findings on the gravity of impacts from invasive alien species on our planet.
Published Lack of evidence hampers progress on corporate-led ecosystem restoration


An international team of scientists analysed publicly available sustainability reports released by 100 of the world's largest companies and found that around two-thirds of these global corporations are undertaking ecosystem restoration. However, the results highlight that despite many businesses claiming to actively rebuild damaged ecosystems, we know very little about what is actually being achieved.
Published Ravenous black hole consumes three Earths'-worth of star every time it passes


Massive burst of X-rays detected by astronomers indicates material three times the mass of Earth burning up in a black hole. They observed a star like our own Sun being eaten away every time it orbits close. First time a Sun-like star being repeatedly disrupted by a low mass black hole has been seen, opening the possibility of a range of star and black hole combinations to be discovered.
Published Capturing carbon in savannas: New research examines role of grasses for controlling climate change


New research shows that, in addition to trees, humble grasses also play an essential role in capturing carbon.
Published Vast bubble of galaxies discovered, given Hawaiian name



The immense bubble is 820 million light years from Earth and believed to be a fossil-like remnant of the birth of the universe.
Published Balancing biodiversity, climate change, food for a trifecta


Scientists identify ways landowners in rural Brazil can find win-win situations with biodiversity and farming.
Published Invasive species are animals, too: Considering a humane approach


Invasive alien species are animals that may pose a threat to biodiversity, but it's time to deal with that threat in a more ethical way.
Published Large herbivores keep invasive plants at bay


Elephants, buffaloes and other heavy herbivores are effective against invasive plants. This is the conclusion of a new study that used Indian data, including data from the world's largest survey of wildlife based on camera traps. But smaller animals can do the same: you don't need elephants to get the same effect, the researchers point out.
Published Farms that create habitat key to food security and biodiversity


Diversified farming is an important complement to forest protections for reversing tropical biodiversity declines.
Published Flowering for naught: 120 years with nothing to show



Flowering for some plants is a yearly occurrence, for others, it is a once-in-a-lifetime event. A widespread species of bamboo in Japan, Phyllostachys nigra var. henonis, takes this one-time flowering event and pushes it to the extreme: they flower once every 120 years before dying to make way for the next generation. Researchers have realized there might be another issue at hand with this monocarpic species, which is the lack of germination of the seeds from a majority of the flowering specimens. Implications of a once dense field of bamboo, something that serves both as a food source and a source of material for crafts, turning to grassland for several years until the regeneration of bamboo begins to start somehow, can impact the ecology of the area in addition to the country's economy.
Published Webb reveals new structures within iconic supernova


NASA's James Webb Space Telescope has begun the study of one of the most renowned supernovae, SN 1987A (Supernova 1987A). Located 168,000 light-years away in the Large Magellanic Cloud, SN 1987A has been a target of intense observations at wavelengths ranging from gamma rays to radio for nearly 40 years, since its discovery in February of 1987. New observations by Webb's NIRCam (Near-Infrared Camera) provide a crucial clue to our understanding of how a supernova develops over time to shape its remnant.
Published Scientists detect and validate the longest-period exoplanet found with TESS


Scientists have detected and validated two of the longest-period exoplanets found by TESS to date. These long period large exoplanets orbit a K dwarf star and belong to a class of planets known as warm Jupiters, which have orbital periods of 10-200 days and are at least six times Earth's radius. This recent discovery offers exciting research opportunities for the future of finding long-period planets that resemble those in our own solar system.
Published New giant planet evidence of possible planetary collisions


A Neptune-sized planet denser than steel has been discovered by an international team of astronomers, who believe its composition could be the result of a giant planetary clash.
Published Coastal fisheries show surprising resilience to marine heat waves


New research found that marine heat waves -- prolonged periods of unusually warm ocean temperatures -- haven't had a lasting effect on the fish communities that feed most of the world. The finding is in stark contrast to the devastating effects seen on other marine ecosystems cataloged by scientists after similar periods of warming, including widespread coral bleaching and harmful algal blooms.
Published Telescopes help unravel pulsar puzzle


With a remarkable observational campaign that involved 12 telescopes both on the ground and in space, including three European Southern Observatory (ESO) facilities, astronomers have uncovered the strange behavior of a pulsar, a super-fast-spinning dead star. This mysterious object is known to switch between two brightness modes almost constantly, something that until now has been an enigma. But astronomers have now found that sudden ejections of matter from the pulsar over very short periods are responsible for the peculiar switches.
Published Male crested macaques more likely to respond to offspring screams recruiting support



When infants are involved in agonistic conflicts, male crested macaques (Macaca nigra) are more likely to respond to screams from their own offspring. This is the conclusion of a recent study led by behavioral ecologists. The researchers studied the behavior of crested macaques in the Tangkoko Nature Reserve on Sulawesi, Indonesia, over a 24-month period (2008 to 2010).
Published Quantum discovery offers glimpse into other-worldly realm



Experiments promote a curious flipside of decaying monopoles: A reality where particle physics is quite literally turned on its head
Published Broken by bison, aspen saplings having a tough time in northern Yellowstone


In northern Yellowstone National Park, saplings of quaking aspen, an ecologically important tree in the American West, are being broken by a historically large bison herd, affecting the comeback of aspen from decades of over-browsing by elk.
