Phys.org / Listening for extinction: Study finds areas of critical concern for northern spotted owls
Northern spotted owl populations are approaching or have already crossed functional extinction across large areas of the Pacific Northwest, a new study, published in Ecological Applications found. Researchers used artificial ...
Medical Xpress / AI helps identify regulatory hub for aging in hematopoietic stem cells
Stem cells possess the unique ability to self-renew and transform into different types of cells. For example, rare hematopoietic stem cells found in bone marrow can become any type of blood cell. Throughout life, they can ...
Phys.org / How chromosomes find their partners
For a long time, so-called satellite DNA was considered largely worthless. Now, ETH Zurich researchers have shown in fruit flies that these repetitive sections of genetic material act as a kind of barcode, enabling the correct ...
Phys.org / Even protected Florida wetlands can't escape microplastic pollution
Microplastics are turning up almost everywhere—from oceans and rivers to soils and sediments—yet far less is known about what happens when they enter freshwater wetlands. Often overlooked in favor of marine and coastal environments, ...
Phys.org / Tax break 'megadeals' spurred innovation in local communities
When cities, counties or states provide corporations with big tax breaks to lure factories, corporate headquarters and other facilities, the economic benefits may go beyond the new jobs and investments the companies bring ...
Phys.org / Sharpening an essential tool for biotechnology
Scientists at the Department of Energy (DOE)'s Oak Ridge National Laboratory (ORNL) have shown that more than 93% of possible E. coli CRISPR-Cas9 guide RNAs—molecules that direct the gene-editing CRISPR tool to the right ...
Phys.org / New workflow helps ecologists measure how individual animals use their habitat
A researcher has developed a new, reproducible workflow that lets ecologists measure, in a standardized way, how individual animals within a species differ in their habitat use, based on GPS tracking data. The tool was developed ...
Medical Xpress / Why men can struggle with weight-loss initiatives
A new study has identified why many men struggle with weight loss, finding that traditional diet programs are often perceived as too restrictive and primarily aimed at women. The research, published in PLOS One and led by ...
Phys.org / New gallery of galaxies from NASA's Chandra X-ray Observatory released
Galaxies are like cosmic gems, each with characteristics including size and shape that make them distinct. A new gallery released today from NASA's Chandra X-ray Observatory and other telescopes displays a collection of galactic ...
Tech Xplore / Who does AI consider an expert? New benchmark shows bias across 22 LLMs
AI chatbots powered by large language models (LLMs) are widely used as recommender systems. While accelerating access to information, AI can also give factually incorrect responses or propagate societal biases.
Phys.org / A tiny drop of water is all that's needed to find threatened frogs
New James Cook University research has used highly sensitive environmental DNA (e-DNA) techniques to find two species of threatened frogs in places they've never been seen before—and find another still struggling to recover ...
Medical Xpress / Viral eating videos linked to body image concerns and disordered eating symptoms
Millions of people watch social media stars consume enormous amounts of food online, but new research suggests these viral eating videos could be contributing to how viewers think about their bodies and their relationship ...
