Published Lightning identified as the leading cause of wildfires in boreal forests, threatening carbon storage



Most wildfires in boreal forests, such as those in Canada, are caused by lightning strikes, according to a study aimed at attributing fire ignition sources globally.
Published A fifth of European Red List flora and fauna species may be at risk of extinction



A new analysis of 14,669 threatened species of plants and animals found in Europe reveals that about one fifth face the risk of extinction, and that agricultural land-use change poses a significant threat to these species.
Published 'Alien' wasps thriving in tropical forests



Researchers say they have discovered high diversity of Darwin wasps in a tropical rainforest in Brazil, wasps which were previously thought to thrive more in cooler habitats.
Published The metabolism of bacteria under the microscope: New method reveals host-microbe interactions



The fascinating world of bacteria that live as symbionts or parasites in animal hosts often remains a mystery to researchers. A research team has made a breakthrough that provides insights into this mysterious micro-world.
Published 450-million-year-old organism finds new life in Softbotics



Researchers have used fossil evidence to engineer a soft robotic replica of pleurocystitids, a marine organism that existed nearly 450 million years ago and is believed to be one of the first echinoderms capable of movement using a muscular stem.
Published Video technology could transform how scientists monitor changes in species evolution and development



New research combines microscope and video technology to analyze how different species develop, and how changes in the timings of any developments can be tracked. A detailed analysis of the Energy Proxy Traits (EPTs) that result from these processes has provided researchers with the first evidence that traditionally measured timings of developmental events are associated with far broader changes to the full set of an embryo's observable characteristics.
Published Two fins are better than one: Fish synchronize tail fins to save energy



They say two heads are better than one. But in the world of fish, it appears two fins are better than one. Researchers have produced a theoretical model that demonstrates the underlying mechanisms behind how fish will synchronize their fin movements to ride each other's vortices, thereby saving energy.
Published Threatened sharks and rays caught off Cyprus



Sharks and rays from threatened species are being caught off northern Cyprus, according to a new study by scientists who are working with local authorities and fishers to protect the animals.
Published Crust-forming algae are displacing corals in tropical waters worldwide



Over the past few decades, algae have been slowly edging corals out of their native reefs across the globe by blocking sunlight, wearing the corals down physically, and producing harmful chemicals. But in recent years, a new type of algal threat has surfaced in tropical regions like the Caribbean -- one that spreads quickly and forms a crust on top of coral and sponges, suffocating the organisms underneath and preventing them from regrowing. Marine biologists report that peyssonnelioid alga crusts, or PACs, are expanding quickly across reefs worldwide, killing off corals and transforming entire ecosystems.
Published The kids aren't alright: Saplings reveal how changing climate may undermine forests



Researchers studied how young trees respond to a hotter, drier climate. Their findings can help shape forest management policy and our understanding of how landscapes will change.
Published New secrets about cat evolution revealed



By comparing genomes of several cat species, the project has helped researchers understand why cat genomes tend to have fewer complex genetic variations (such as rearrangements of DNA segments) than other mammal groups, like primates. It also revealed new insights into which parts of cat DNA are most likely to evolve rapidly and how they play a role in species differentiation.
Published Rats have an imagination, new research suggests



Researchers have developed a novel system to probe a rat's thoughts, finding that animals can control their brain activity to imagine remote locations.
Published Damaging thunderstorm winds increasing in central U.S.



Destructive winds that flow out of thunderstorms in the central United States are becoming far more widespread with warming temperatures, according to new research. A new study shows that the central U.S. experienced a fivefold increase in the geographic area affected by damaging thunderstorm straight line winds in the past 40 years.
Published Where is a sea star's head? Maybe just about everywhere



A new study that combines genetic and molecular techniques helps solve the riddle of sea star (commonly called starfish) body plans, and how sea stars start life with bilateral body symmetry -- just like humans -- but grow up to be adults with fivefold 'pentaradial' symmetry.
Published How the fish got its shoulder



A new analysis of the bones and muscles in ancient fish gives new clues about how the shoulder evolved in animals -- including us.
Published The ringed seals in Ilulissat Icefjord, Greenland are special



Local hunters in the Icefjord near Ilulissat have long known about a special ringed seal -- the Kangia seal -- which is significantly larger and has a markedly different fur color and pattern than typical Arctic ringed seals. Now scientific studies have shown that the Kangia ringed seal has been isolated from other ringed seals for a long period of time -- more than 100,000 years.
Published Ocean warming is accelerating, and hotspots reveal which areas are absorbing the most heat



A new study reveals increasing warming rates in the world's oceans in recent decades and the locations with the greatest heat uptake.
Published Dam removals, restoration project on Klamath River expected to help salmon, researchers conclude



The world's largest dam removal and restoration project currently underway on the Klamath River in Oregon and California will aid salmon populations that have been devastated by disease and other factors. However, it will not fully alleviate challenges faced by the species, a team of researchers conclude.
Published Shifting nesting timing not enough to prevent fewer sea turtle hatchlings



New research shows that potential adaptive responses by sea turtles, such as shifting the timing of when they nest, may not be enough to counteract the projected impacts from climate change on hatchling production.
Published Climate-smart cows could deliver 10-20x more milk in Global South



A team of animal scientists is set to deliver a potential game changer for subsistence farmers in Tanzania: cows that produce up to 20 times the milk of indigenous breeds.
