Published Mediterranean marine worm has developed enormous eyes
(via sciencedaily.com) Original source Scientists are amazed at the discovery of a bristle worm with such sharp-seeing eyes that they can measure up to those of mammals and octopuses. The researchers suspect that these marine worms may have a secretive language, which uses UV light only seen by their own species. The advanced vision of such a primitive creature helps to finally settle an epic debate about the evolution of eyes.
Published Integrated dataset enables genes-to-ecosystems research
(via sciencedaily.com) Original source A new dataset bridging molecular information about the poplar tree microbiome to ecosystem-level processes has been released. The project aims to inform research regarding how natural systems function, their vulnerability to a changing climate, and ultimately how plants might be engineered for better performance as sources of bioenergy and natural carbon storage.
Published Ocean waves propel PFAS back to land
(via sciencedaily.com) Original source A new study reveals that PFAS re-emit into the air from crashing ocean waves at levels comparable to or greater than other sources, establishing a cyclical transport process for these 'forever chemicals' between land and sea.
Published In the evolution of walking, the hip bone connected to the rib bones
(via sciencedaily.com) Original source A new reconstruction of the 375-million-year-old fossil fish Tiktaalik -- a close relative of limbed vertebrates -- used micro-CT to reveal bones still embedded in matrix. The reconstruction shows that the fish's ribs likely attached to its pelvis, an innovation thought to be crucial to supporting the body and for the eventual evolution of walking.
Published Common loons threatened by declining water clarity
(via sciencedaily.com) Original source The Common Loon, an icon of the northern wilderness, is under threat from climate change due to reduced water clarity, according to a new study. The study followed up an earlier paper that showed substantial reproductive decline in the author's study area in northern Wisconsin.
Published Can language models read the genome? This one decoded mRNA to make better vaccines
(via sciencedaily.com) Original source Researchers developed a foundational language model to decode mRNA sequences and optimize those sequences for vaccine development. The tool shows broader promise as a means for studying molecular biology.
Published eDNA methods give a real-time look at coral reef health
(via sciencedaily.com) Original source The study underscores the crucial role of microbes in maintaining coral reef health, akin to the human gut microbiome. Hurricanes and disease outbreaks affect coral reef water microbial communities, leading to changes that may support further reef decline. Microbial analysis enables prompt assessment of disturbances' impacts on coral reefs, facilitating timely interventions to support reef ecosystems. Environmental DNA (eDNA) analysis offers a noninvasive approach to study coral microbial communities and diagnose reef health.
Published Heat stress from ocean warming harms octopus vision
(via sciencedaily.com) Original source While climate change has led to an increase in the abundance of octopuses, heat stress from projected ocean warming could impair their vision and impact the survivability of the species.
Published Ocean floor a 'reservoir' of plastic pollution
(via sciencedaily.com) Original source New science has taken a deep dive into plastic waste, providing the first estimate of how much ends up on the sea floor.
Published The life aquatic: A game changer for frog vision, but little difference between night and day
(via sciencedaily.com) Original source Frogs display a remarkable diversity of species as a whole, but does the same hold true for their visual abilities? A new study sought to answer this question by collaborating with researchers in Australia, Belgium, Brazil, Cameroon, Ecuador, Equatorial Guinea, French Guiana, Gabon, Seychelles, Sweden, United Kingdom and the United States, to get a sample of a diverse array of frogs to study the visual pigments found in their eyes. The researchers found this diversity is largely 'reflected' in the pigments, especially for aquatic frogs versus those living on the ground or in trees. They found little difference with the small groups of frogs that have adapted to daytime conditions as opposed to their nocturnal cousins.
Published Rusty-patched bumblebee's struggle for survival found in its genes
(via sciencedaily.com) Original source The rusty-patched bumblebee, once common in the United States, has declined from about 90% of its former range. Researchers conducted the first range-wide genetic study of the endangered species to inform recovery efforts.
Published Prairie voles display signs of human-like depression
(via sciencedaily.com) Original source Researchers make the case that prairie voles, small rodents that are found throughout the central United States and Canada, can be effectively used as animal models to further the study of clinical depression.
Published 'Diverse' agriculture benefits people and the environment at the same time
(via sciencedaily.com) Original source A new analysis from 2,655 farms on five continents suggests that moving away from industrial, monoculture farming could benefit both the planet and people.
Published Shy sea anemones are more likely to survive heatwaves
(via sciencedaily.com) Original source A study shows that sea anemones that react more slowly to change can survive a heatwave better than individuals that change their behavior quickly.
Published Tracing the largest solar storm in modern times from tree rings in Lapland
(via sciencedaily.com) Original source A research group was able to measure a spike in radiocarbon concentration of trees in Lapland that occurred after the Carrington flare. This discovery helps to prepare for dangerous solar storms.
Published Adult fish struggle to bounce back in marine protected areas
(via sciencedaily.com) Original source Many marine protected areas are falling short of their most basic purpose: to rebuild struggling fish populations. In a new study, scientists looked at the age breakdown of reef fish in marine protected areas for the first time. They discovered in almost all of them, adult fish populations -- vital to spawning the next generation -- have either flatlined or declined.
Published New research offers insight into the future understanding of MS and its treatments
(via sciencedaily.com) Original source Researchers have developed a new and unique blood test to measure the immune response to the Epstein Barr Virus (EBV) which is the leading risk factor for developing multiple sclerosis (MS). Their findings have implications for future basic research in further understanding the biology of EBV in MS, but also has the potential to be applied in clinical trials that target the virus.
Published Fans are not a magic bullet for beating the heat!
(via sciencedaily.com) Original source A new study throws cold water on the idea that fans can effectively cool you down during extremely hot weather events.
Published Heat flows the secret to order in prebiotic molecular kitchen
(via sciencedaily.com) Original source Biophysicists have demonstrated how heat flows through rock fissures could have created the conditions for the emergence of life.
Published Microbial signature of colorectal cancer-associated mutations identified in new study
(via sciencedaily.com) Original source Researchers have connected KRAS mutations in colorectal cancer to microbial signatures in the gut.
