Published Did animal evolution begin with a predatory lifestyle?



Surprising findings on the development of sea anemones suggest that a predatory lifestyle molded their evolution and had a significant impact on the origin of their nervous system. The researchers were able to show that the young life stages (larvae) of the small sea anemone Aiptasia actively feed on living prey and are not dependent on algae. To capture its prey, the anemone larvae use specialized stinging cells and a simple neuronal network.
Published Polyps as pixels: Innovative technique maps biochemistry of coral reefs



Using an innovative new approach to sampling corals, researchers are now able to create maps of coral biochemistry that reveal with unprecedented detail the distribution of compounds that are integral to the healthy functioning of reefs.
Published A turtle time capsule: DNA found in ancient shell



Paleontologists discover possible DNA remains in fossil turtle that lived 6 million years ago in Panama, where continents collide.
Published Why are killer whales harassing and killing porpoises without eating them?



For decades, fish-eating killer whales in the Pacific Northwest have been observed harassing and even killing porpoises without consuming them —- a perplexing behavior that has long intrigued scientists.
Published Ethical guidelines needed before human research in commercial spaceflight is ready for liftoff



Before human research is conducted during commercial spaceflights, it should be 'ethically cleared to launch,' according to a global team of scientists, health policy experts and commercial spaceflight professionals.
Published Whales Around the World Play With Kelp Clumps



A new article has analyzed another understudied behavior in baleen (filter-feeding) whales such as humpback whales in different populations across the northern and southern hemispheres. They appeared to roll around and 'play' with clumps of kelp and seaweed at the water's surface. The research also emphasizes that the behavior was similar in different individuals, regardless of where in the world it occurred.
Published Atlantic walrus more vulnerable than ever to Arctic warming



Past cycles of climate change, along with human exploitation, have led to only small and isolated stocks of Atlantic walrus remaining. The current population is at high risk of the same issues affecting them severely, according to a new study.
Published Extreme weight loss: Star sheds unexpected amounts of mass just before going supernova



A newly discovered nearby supernova whose star ejected up to a full solar mass of material in the year prior to its explosion is challenging the standard theory of stellar evolution. The new observations are giving astronomers new insight into what happens in the final year prior to a star's death and explosion.
Published New proof for black hole spin



The supermassive black hole at the heart of galaxy M87, made famous by the first picture of a black hole shadow, has yielded another first: the jet shooting out from the black hole has been confirmed to wobble, providing direct proof that the black hole is spinning.
Published Study sheds new light on strange lava worlds


In a new study, scientists have shown that sweeping molten oceans have a large influence on the observed properties of hot rocky Super-Earths, such as their size and evolutionary path.
Published New insights into the atmosphere and star of an exoplanet


A new study of the intriguing TRAPPIST-1 exoplanetary system has demonstrated the complex interaction between the activity of the system's star and its planetary features.
Published Theories about the natural world may need to change to reflect human impact


New research has validated at scale, one of the theories that has underpinned ecology for over half a century. In doing so, the findings raise further questions about whether models should be revised to capture human impacts on natural systems.
Published Hidden supermassive black holes reveal their secrets through radio signals


Astronomers have found a striking link between the amount of dust surrounding a supermassive black hole and the strength of the radio emission produced in extremely bright galaxies.
Published Rivers contain hidden sinks and sources of microplastics



New research represents the first combined analysis of microplastics in water, sediment and air around a major river system. It found significant quantities of microplastics trapped in riverbed sediments, and also found they were being transported through the air and the flow of the river.
Published Ocean acidification makes ecologically important seaweed species fragile



Ocean acidification will likely almost triple by the end of the century -- a drastic environmental change that could impact important marine species like fleshy seaweeds, algae that grow vertically and promote biodiversity in more than a third of the world's coastline. To get a better idea of how seaweeds might fare in a rapidly acidifying ocean, a team of marine scientists subjected a common fleshy seaweed species to the acidification levels expected by the end of the century. They report that increased acidification impacted the seaweed's chemical balance, made both its structure and its tissues weaker, and reduced its overall chances of survival.
Published Astronomers discover newborn galaxies with the James Webb Space Telescope


With the launch of the James Webb Space Telescope, astronomers are now able to peer so far back in time that we are approaching the epoch where we think that the first galaxies were created. Throughout most of the history of the Universe, galaxies seemingly tend to follow a tight relation between how many stars they have formed, and how many heavy elements they have formed. But for the first time we now see signs that this relation between the amount of stars and elements does not hold for the earliest galaxies. The reason is likely that these galaxies simply are in the process of being created, and have not yet had the time to create the heavy elements.
Published Astronomers find abundance of Milky Way-like Galaxies in early Universe, rewriting cosmic evolution theories


Galaxies from the early Universe are more like our own Milky Way than previously thought, flipping the entire narrative of how scientists think about structure formation in the Universe, according to new research.
Published Carbon source found on surface of Jupiter's moon Europa


Astronomers using data from NASA's James Webb Space Telescope have identified carbon dioxide in a specific region on the icy surface of Europa.
Published Understanding the sex life of coral gives hope of clawing it back from the path to extinction



Scientists have mapped the reproductive strategies and life cycle of an endangered coral species, the purple cauliflower soft coral Dendronephthya australis. Lab-grown larvae have been successfully introduced back into the wild.
Published Mussels able to adjust heart rate to cope with marine heatwaves



New research shows that mussels are pretty crafty sea creatures: able to withstand marine heatwaves by adjusting their heart rate and other physiological functions, boding well for their survival in future decades as the world heats up.
