Published A new pulsar buried in a mountain of data
(via sciencedaily.com) Original source Astronomers have discovered the first millisecond pulsar in the stellar cluster Glimpse-CO1.
Published AI-powered study explores under-studied female evolution
(via sciencedaily.com) Original source Pioneering AI-powered research on butterflies has probed the under-studied evolution of females and adds to a debate between Charles Darwin and Alfred Russel Wallace.
Published Researchers identify unique survival strategies adopted by fish in the world's warmest waters
(via sciencedaily.com) Original source A team of researchers have identified unexpected ways coral reef fish living in the warmest waters on earth, in the Arabian Gulf, have adapted to survive extreme temperatures.
Published The evidence is mounting: humans were responsible for the extinction of large mammals
(via sciencedaily.com) Original source Human hunting, not climate change, played a decisive role in the extinction of large mammals over the last 50,000 years. This conclusion comes from researchers who reviewed over 300 scientific articles from many different fields of research.
Published Choose where to plant energy crops wisely to minimise loss of biodiversity
(via sciencedaily.com) Original source In the fight to protect biodiversity and limit climate change, the world will reap what it sows.
Published Sixty-million-year-old grape seeds reveal how the death of the dinosaurs may have paved the way for grapes to spread
(via sciencedaily.com) Original source Scientists discovered the oldest fossil grapes in the Western Hemisphere, which help show how after the death of the dinosaurs, grapes spread across the world.
Published Tiny bright objects discovered at dawn of universe baffle scientists
(via sciencedaily.com) Original source A recent discovery by NASA's James Webb Space Telescope (JWST) confirmed that luminous, very red objects previously detected in the early universe upend conventional thinking about the origins and evolution of galaxies and their supermassive black holes.
Published Ecologists reconstruct the history of biodiversity in the Indo-Australian archipelago and its rise as a hotspot
(via sciencedaily.com) Original source The Coral Triangle, also known as the Indo-Australian Archipelago, is renowned for having the greatest marine biodiversity on our planet. Despite its importance, the detailed evolutionary history of this biodiversity hotspot has remained largely a mystery. An international research team has now shed light on this history, reconstructing how biodiversity in the region has developed over the past 40 million years.
Published Climate change to shift tropical rains northward
(via sciencedaily.com) Original source Atmospheric scientists predict that unchecked carbon emissions will force tropical rains to shift northward in the coming decades, which would profoundly impact agriculture and economies near the Earth's equator. The northward rain shift would be spurred by carbon emissions that influence the formation of the intertropical convergence zones that are essentially atmospheric engines that drive about a third of the world's precipitation.
Published Too many missing satellite galaxies found
(via sciencedaily.com) Original source Bringing us one step closer to solving the 'missing satellites problem,' researchers have discovered two new satellite galaxies.
Published New class of Mars quakes reveals daily meteorite strikes
(via sciencedaily.com) Original source An international team of researchers combine orbital imagery with seismological data from NASA's Mars InSight lander to derive a new impact rate for meteorite strikes on Mars. Seismology also offers a new tool for determining the density of Mars' craters and the age of different regions of a planet.
Published Projected loss of brown macroalgae and seagrasses with global environmental change
(via sciencedaily.com) Original source Researchers predict that climate change will drive a substantial redistribution of brown seaweeds and seagrasses at the global scale. The projected changes are alarming due to the fundamental role seaweeds and seagrasses in coastal ecosystems and provide evidence of the pervasive impacts of climate change on marine life.
Published The density difference of sub-Neptunes finally deciphered
(via sciencedaily.com) Original source The majority of stars in our galaxy are home to planets. The most abundant are the sub-Neptunes, planets between the size of Earth and Neptune. Calculating their density poses a problem for scientists: depending on the method used to measure their mass, two populations are highlighted, the dense and the less dense. Is this due to an observational bias or the physical existence of two distinct populations of sub-Neptunes? Recent work argues for the latter.
Published Ammonites' fate sealed by meteor strike that wiped out dinosaurs
(via sciencedaily.com) Original source Ammonites were not in decline before their extinction, scientists have found.
Published Invasive ants spread by hitchhiking on everyday vehicles
(via sciencedaily.com) Original source Ants might spread to new locations by stowing away on everyday vehicles. Previously, this was thought to occur mostly on agricultural equipment.
Published Why the harsh Snowball Earth kick-started our earliest multicellular ancestors
(via sciencedaily.com) Original source Why did multicellularity arise? Solving that mystery may help pinpoint life on other planets and explain the vast diversity and complexity seen on Earth today, from sea sponges to redwoods to human society. A new article shows how specific physical conditions -- especially ocean viscosity and resource deprivation -- during the global glaciation period known as Snowball Earth could have driven eukaryotes to turn multicellular.
Published Ocean's loss of oxygen caused massive Jurassic extinction: Could it happen again?
(via sciencedaily.com) Original source Researchers have found a chemical clue in Italian limestone that explains a mass extinction of marine life in the Early Jurassic period, 183 million years ago. Volcanic activity pumped out CO2, warming oceans and lowering their oxygen levels. The findings may foretell the impact climate change and oxygen depletion might have on today's oceans.
Published Pillars of creation star in new visualization from NASA's Hubble and Webb telescopes
(via sciencedaily.com) Original source Made famous in 1995 by NASA's Hubble Space Telescope, the Pillars of Creation in the heart of the Eagle Nebula have captured imaginations worldwide with their arresting, ethereal beauty. Now, NASA has released a new 3D visualization of these towering celestial structures using data from NASA's Hubble and James Webb space telescopes. This is the most comprehensive and detailed multiwavelength movie yet of these star-birthing clouds.
Published Plankton researchers urge their colleagues to mix it up
(via sciencedaily.com) Original source A new article encourages researchers to focus their attention on mixoplankton, providing a set of methodologies to help expand our understanding of this critically important component of the marine ecosystem.
Published Frog 'saunas' a lifeline for endangered frog populations
(via sciencedaily.com) Original source New biologist-designed shelters will help endangered frogs survive the devastating impacts of a deadly fungal disease by regulating their body temperature to fight off infections.
