Published Summer solstice triggers synchronized beech tree reproduction across Europe
(via sciencedaily.com) Original source A new study has found that the summer solstice acts as a 'starting gun' to synchronize beech tree reproduction across vast distances in Europe, affecting ecosystem functions.
Published Giant sequoias are a rapidly growing feature of the UK landscape
(via sciencedaily.com) Original source Imported giant sequoia trees are well adapted to the UK, growing at rates close to their native ranges and capturing large amounts of carbon during their long lives, finds a new study.
Published Rainforest's next generation of trees threatened 30 years after logging
(via sciencedaily.com) Original source Rainforest seedlings are more likely to survive in natural forests than in places where logging has happened -- even if tree restoration projects have taken place, new research shows.
Published Peering into the tendrils of NGC 604 with NASA's Webb
(via sciencedaily.com) Original source The formation of stars and the chaotic environments they inhabit is one of the most well-studied, but also mystery-shrouded, areas of cosmic investigation. The intricacies of these processes are now being unveiled like never before by NASA's James Webb Space Telescope.
Published Mapping the future's sweet spot for clean energy and biodiversity
(via sciencedaily.com) Original source A new study of Joshua trees, kit foxes and solar energy developments highlights the need to consider climate-induced range shifts for species as we expand clean energy.
Published Earth's earliest forest revealed in Somerset fossils
(via sciencedaily.com) Original source The oldest fossilized forest known on Earth -- dating from 390 million years ago -- has been found in the high sandstone cliffs along the Devon and Somerset coast of South West England.
Published Finding new physics in debris from colliding neutron stars
(via sciencedaily.com) Original source Neutron star mergers are a treasure trove for new physics signals, with implications for determining the true nature of dark matter, according to physicists.
Published Astronomers spot oldest 'dead' galaxy yet observed
(via sciencedaily.com) Original source A galaxy that suddenly stopped forming new stars more than 13 billion years ago has been observed by astronomers. Using the James Webb Space Telescope, astronomers have spotted a 'dead' galaxy when the universe was just 700 million years old, the oldest such galaxy ever observed.
Published Discovery tests theory on cooling of white dwarf stars
(via sciencedaily.com) Original source Open any astronomy textbook to the section on white dwarf stars and you'll likely learn that they are 'dead stars' that continuously cool down over time. Astronomers are challenging this theory after discovering a population of white dwarf stars that stopped cooling for more than eight billion years.
Published Space tourism? Cosmic radiation exposure
(via sciencedaily.com) Original source Space weather experts are urging regulators and space tourism innovators to work together to protect their passengers and crews from the risks of space weather radiation exposure.
Published Groundbreaking survey reveals secrets of planet birth around dozens of stars
(via sciencedaily.com) Original source A team of astronomers has shed new light on the fascinating and complex process of planet formation. The research brings together observations of more than 80 young stars that might have planets forming around them, providing astronomers with a wealth of data and unique insights into how planets arise in different regions of our galaxy.
Published What makes black holes grow and new stars form? Machine learning helps solve the mystery
(via sciencedaily.com) Original source It takes more than a galaxy merger to make a black hole grow and new stars form: machine learning shows cold gas is needed too to initiate rapid growth -- new research finds.
Published Juno spacecraft measures oxygen production on Jupiter's moon, Europa
(via sciencedaily.com) Original source NASA's Juno spacecraft has directly measured charged oxygen and hydrogen molecules from the atmosphere of one of Jupiter's largest moons, Europa. These observations provide key constraints on the potential oxygenation of its subsurface ocean.
Published 8 in 10 lizards could be at risk due to deforestation
(via sciencedaily.com) Original source These reptiles move around tree trunks to seek warmth or shade. With trees disappearing, they would have trouble controlling their body temperature, a new study shows.
Published An inside look at Beech tree disease
(via sciencedaily.com) Original source A new study found differences at the cellular level of leaves from infected Beech trees -- variations that may account for tree mortality.
Published Webb unlocks secrets of one of the most distant galaxies ever seen
(via sciencedaily.com) Original source Looking deeply into space and time, astronomers have studied the exceptionally luminous galaxy GN-z11, which existed when our 13.8 billion-year-old universe was only about 430 million years old.
Published In wake of powerful cyclone, remarkable recovery of Pacific island's forests
(via sciencedaily.com) Original source After one of the most intense cyclones in world history tore through the Pacific island of Tanna in Vanuatu, new research showed the resilience of the island's forests.
Published New insights on how galaxies are formed
(via sciencedaily.com) Original source Astronomers can use supercomputers to simulate the formation of galaxies from the Big Bang 13.8 billion years ago to the present day. But there are a number of sources of error. An international research team has spent a hundred million computer hours over eight years trying to correct these.
Published Ultraviolet radiation from massive stars shapes planetary systems
(via sciencedaily.com) Original source Up to a certain point, very luminous stars can have a positive effect on the formation of planets, but from that point on the radiation they emit can cause the material in protoplanetary discs to disperse.
Published Astronomers measure heaviest black hole pair ever found
(via sciencedaily.com) Original source Using archival data from the Gemini North telescope, a team of astronomers has measured the heaviest pair of supermassive black holes ever found. The merging of two supermassive black holes is a phenomenon that has long been predicted, though never observed. This massive pair gives clues as to why such an event seems so unlikely in the Universe.
