Published Slugs and snails love the city, unlike other animals



Most native species avoid more urbanized areas of Los Angeles, but slugs and snails may actually prefer these environments, according to a new study.
Published Wild megalopolis: Study shows unexpected pockets of biodiversity pepper Los Angeles



Researchers, in partnership with the city of Los Angeles, have developed the urban association index to help identify how well or poorly individual wildlife species are doing in the city. The researchers found unexpected pockets of biodiversity deep in the city, but they say it will still be a challenge to elevate Los Angeles' overall level of biodiversity.
Published Marine Protected Areas don't line up with core habitats of rare migratory fish, finds new research



62% of Marine Protected Areas (MPAs) designated to protect rare migratory fish species are outside of their core habitats, according to a new modeling study.
Published Smarter foragers do not forage smarter



Why do primates have big brains? In the Panamanian rainforest, scientists pitted large-brained primates against smaller-brained mammals to find out who was the smartest forager.
Published Global activity of seafloor biodiversity mapped



A team of scientists has used artificial intelligence (AI) to map the activities of seafloor invertebrate animals, such as worms, clams and shrimps, across all the oceans of the world.
Published Birth of universe's earliest galaxies observed for first time



Researchers have now seen the formation of three of the earliest galaxies in the universe, more than 13 billion years ago. The sensational discovery contributes important knowledge about the universe.
Published Intriguing nearby world sized between Earth, Venus



Astronomers have discovered a planet between the sizes of Earth and Venus only 40 light-years away.
Published Planet hunters unveil massive catalog of strange worlds



While thousands of planets have been discovered around other stars, relatively little is known about them. A NASA catalog featuring 126 exotic, newly discovered worlds includes detailed measurements that allow for comparisons with our own solar system.
Published First pictures from Euclid satellite reveal billions of orphan stars



The first scientific pictures from the Euclid satellite mission have revealed more than 1,500 billion orphan stars scattered throughout the Perseus cluster of galaxies.
Published Potentially habitable 'exo-Venus' with Earth-like temperature discovered



Astronomers have made the rare and tantalizing discovery of an Earth-like exoplanet 40 light-years away that may be just a little warmer than our own world. The potentially-habitable planet, named Gliese 12 b, orbits its host star every 12.8 days, is comparable in size to Venus -- so slightly smaller than Earth -- and has an estimated surface temperature of 42 C (107 F), which is lower than most of the 5,000-odd exoplanets confirmed so far. That is assuming it has no atmosphere, however, which is the crucial next step to establishing if it is habitable.
Published Using wobbling stellar material, astronomers measure the spin of a supermassive black hole for the first time



Astronomers have a new way to measure how fast a black hole spins, by using the wobbly aftermath from its stellar feasting. The results offer a new way to probe supermassive black holes and their evolution across the universe.
Published Conservation of nature's strongholds needed to halt biodiversity loss



To achieve global biodiversity targets, conservationists and governments must prioritize the establishment and effective management of large, interconnected protected areas with high ecological integrity, researchers argue in a new essay.
Published Complete stellar collapse: Unusual star system proves that stars can die quietly



University of Copenhagen astrophysicists help explain a mysterious phenomenon, whereby stars suddenly vanish from the night sky. Their study of an unusual binary star system has resulted in convincing evidence that massive stars can completely collapse and become black holes without a supernova explosion.
Published Regional differences in bird diversity in agroforestry systems



The diversity and ecological functionality of bird communities in tropical agroforestry systems are shaped by the surrounding landscape, in particular the extent and composition of the forest.
Published Improving statistical methods to protect wildlife populations



In human populations, it is relatively easy to calculate demographic trends and make projections of the future if data on basic processes such as births and immigration is known. The data, given by individuals, can be also death and emigration, which subtract. In the wild, on the other hand, understanding the processes that determine wildlife demographic patterns is a highly complex challenge for the scientific community. Although a wide range of methods are now available to estimate births and deaths in wildlife, quantifying emigration and immigration has historically been difficult or impossible in many populations of interest, particularly in the case of threatened species.
Published The impacts of climate change on food production



A new study shows that climate change has led to decreased pollen production from plants and less pollen diversity than previously thought, which could have a significant impact on food production.
Published Webb Telescope offers first glimpse of an exoplanet's interior



A surprisingly low amount of methane and a super-sized core hide within the cotton candy -- like planet WASP-107 b.
Published Cloudy waters causes African fish to develop bigger eyes



Variations in water quality can impact the development of the visual system of one species of African fish, suggests a new study.
Published Scale matters in determining vulnerability of freshwater fish to climate changes



A team explored the influence the spatial extent of research -- the geographical coverage of data collected -- has on evaluating the sensitivity of different fish species to climate change.
Published Differing values of nature can still lead to joined up goals for sustainability



Recognizing and respecting the different ways nature is valued can enable better environmental decision-making, according to new research.
