Published Blue tit population booms with moths on the menu



Researchers found that years when moth numbers were up resulted in increased population growth for the blue tit.
Published Gulls swap natural for urban habitats, machine-learning study finds



The study is the first of its kind to compile a three-year dataset using a citizen science-based, opportunistic research method to include a large sample of gulls and other sub-Arctic birds in urban Alaska. The study provides a current snapshot of the habitat shift to an urban landscape.
Published A new perspective on the temperature inside tropical forests



New worldwide maps of temperatures inside tropical forests show that global warming affect different way in different parts of the forests. Undergrowth level temperature of the tropical forests can be even 4 degrees less than average temperature of the area.
Published Uncovering the secrets behind the silent flight of owls



Owls produce negligible noise while flying. While many studies have linked the micro-fringes in owl wings to their silent flight, the exact mechanisms have been unclear. Now, a team of researchers has uncovered the effects of these micro-fringes on the sound and aerodynamic performance of owl wings through computational fluid dynamic simulations. Their findings can inspire biomimetic designs for the development of low-noise fluid machinery.
Published Wolves and elk are (mostly) welcome back in Poland and Germany's Oder Delta region, survey shows



An online survey conducted in Germany and Poland shows that large parts of the participants support the return of large carnivores and herbivores, such as wolves and elk, to the Oder Delta region. Presented with different rewilding scenarios, the majority of survey participants showed a preference for land management that leads to the comeback of nature to the most natural state possible. Locals, on the other hand, showed some reservations.
Published Deepwater Horizon oil spill study could lead to overhaul of cleanup processes worldwide



New research could lead to major improvements in marine oil spill cleanup processes. The innovative study assessed the impact of the Deepwater Horizon oil spill on microscopic seawater bacteria that perform a significant role in ecosystem functioning.
Published Sea otters helped prevent widespread California kelp forest declines over the past century



The study reveals dramatic regional kelp canopy changes along the California coast over a 100-year period. During this time there was a significant increase in kelp forest canopy along the central coast, the only region of California where southern sea otters survived after being hunted nearly to extinction for their fur in the 1800s. Contrastingly, kelp canopy decreased in northern and southern regions. At the century scale, the species' favorable impact on kelp forests along the central coast nearly compensated for the kelp losses along both northern and southern California resulting in only a slight overall decline statewide during this period.
Published Lightest black hole or heaviest neutron star? MeerKAT uncovers a mysterious object in Milky Way



An international team of astronomers have found a new and unknown object in the Milky Way that is heavier than the heaviest neutron stars known and yet simultaneously lighter than the lightest black holes known.
Published Researchers pump brakes on 'blue acceleration' harming the world ocean



Protecting the world ocean against accelerating damage from human activities could be cheaper and take up less space than previously thought, new research has found.
Published Translating nuclear waste site data into microbial ecosystem insights



A flagship seven-year study that explores how environmental stresses influence different ecological processes shaping the composition and structure of microbial communities in groundwater has now been published.
Published Rain can spoil a wolf spider's day, too



Researchers found that wolf spiders can't signal others or perceive danger from predators as easily on rain-soaked leaves compared to dry ones. Even communicating with would-be mates is harder after it rains.
Published Origin of intense light in supermassive black holes and tidal disruption events revealed



A new study is a significant breakthrough in understanding Tidal Disruption Events (TDEs) involving supermassive black holes. The new simulations accurately replicate the entire sequence of a TDE from stellar disruption to the peak luminosity of the resulting flare.
Published Astronomers detect oldest black hole ever observed



Researchers have discovered the oldest black hole ever observed, dating from the dawn of the universe, and found that it is 'eating' its host galaxy to death.
Published Climate change isn't producing expected increase in atmospheric moisture over dry regions



The warming climate has not lead to an expected increase in atmospheric moisture over arid and semi-arid regions of the world. The finding, which has surprised scientists, indicates that some regions may be even more vulnerable to future wildfires and extreme heat than projected.
Published New AI makes better permafrost maps



New insights from artificial intelligence about permafrost coverage in the Arctic may soon give policy makers and land managers the high-resolution view they need to predict climate-change-driven threats to infrastructure such as oil pipelines, roads and national security facilities.
Published Study delivers detailed photos of galaxies' inner structures



High-resolution images captured by the James Webb Space Telescope are offering powerful insights into the complex dust patterns of nearby star-forming galaxies.
Published Stalagmites as climate archive



When combined with data from tree-ring records, stalagmites can open up a unique archive to study natural climate fluctuations, a research team has demonstrated. The researchers analyzed the isotopic composition of oxygen in a stalagmite formed from calcareous water in a cave in southern Germany. In conjunction with the data acquired from tree rings, they were able to reconstruct short-term climate fluctuations over centuries and correlate them with historically documented environmental events.
Published A new, rigorous assessment of OpenET accuracy for supporting satellite-based water management



Sustainable water management is an increasing concern in arid regions around the world, and scientists and regulators are turning to remote sensing tools like OpenET to help track and manage water resources. OpenET uses publicly available data produced by NASA and USGS Landsat and other satellite systems to calculate evapotranspiration (ET), or the amount of water lost to the atmosphere through soil evaporation and plant transpiration, at the level of individual fields. This tool has the potential to revolutionize water management, allowing for field-scale operational monitoring of water use, and a new study provides a thorough analysis of the accuracy of OpenET data for various crops and natural land cover types.
Published Climate change threatens global forest carbon sequestration, study finds



Climate change is causing Western U.S. forests to be less effective carbon sinks, even as it boosts the productivity of forests in the Eastern U.S., according to new research.
Published Astronomers produce most sensitive radio image ever of ancient star cluster



Astronomers have created the most sensitive radio image ever of a globular cluster, an ancient ball of tightly-packed stars.
