Phys.org / The local costs of remote sensing: Examining the ethics of laser scanning in tropical forests
Laser scanning, often referred to as lidar, has rapidly transformed how tropical forest regions are studied, monitored and understood across academic disciplines. The technology enables researchers to peer through dense forest ...
Phys.org / Bacterial invasion proteins could improve detection of live crop pathogens
Scientists, clinicians, seed companies and others may soon have a new tool in their toolkit for detecting bacterial pathogens, thanks to a new study by researchers in Penn State's College of Agricultural Sciences. The research—published ...
Phys.org / When prepping for disaster, don't forget to pack your teddy bear
Imagine it's the dead of night. Your phone pings with a text—it's a government emergency alert: "Leave your home immediately! Only take with you enough supplies for the next three days." What would you want in your go-bag?
Medical Xpress / New test could dramatically speed diagnosis of hard-to-detect lung infections
A little-known chronic lung disease is silently emerging as a growing public health threat in the U.S. and around the world. Nontuberculous mycobacteria—a group of 200 known environmental bacteria found in soil and water, ...
Phys.org / Tiny oyster larvae rely on gravity to feed
Eastern oyster larvae are only 100–300 micrometers long, but their dense calcium carbonate shells make them substantially heavier than the surrounding seawater. A new study led by the Woods Hole Oceanographic Institution ...
Phys.org / AI updates can sometimes feel like breakups or losses, study finds
Artificial intelligence systems, particularly those powered by large language models and designed to communicate with users on a one-to-one basis, are increasingly used worldwide. Some of these systems, such as Replika, are ...
Phys.org / Deep ocean, familiar trash: Plastic waste found alongside possible new species
It's no secret that plastic and other human trash are a problem for marine life, but our understanding has long focused on the ocean's surface. As described in a study published in PLOS One, a more complete picture is coming ...
Phys.org / A 6-nanometer vapor barrier insulates ice during rapid heating
Put a drop of water into a very hot pan, and it can skitter across the surface on a cushion of vapor. This is known as the Leidenfrost effect. Now, scientists have observed a related phenomenon involving ice and an extremely ...
Phys.org / 'Born-again' star offers rare chance to watch stellar evolution in real time
Astronomers have confirmed that one of the fastest-changing stars ever observed has entered a new stage of its evolution, offering a rare opportunity to watch a star's life unfold on human timescales.
Medical Xpress / Robotic help in high-risk twin pregnancies: Panoramic guidance for a flexible laser scope
In Switzerland, around 2,400 children are born as twins every year. When the fetuses share a placenta, they are connected to one another via blood vessels. If the blood circulation becomes unbalanced, this can be life-threatening ...
Phys.org / Fungi neutralize spruce defense mechanisms with sugar
A research team at the Max Planck Institute for Chemical Ecology discovered a previously unknown strategy by which certain fungi neutralize spruce defense compounds. These fungi are introduced into trees by bark beetles, ...
Phys.org / Hedgehog coronaviruses may threaten cats more than humans, new study finds
Washington State University researchers have discovered how a group of coronaviruses circulating in hedgehogs invades host cells, a key to understanding their potential to jump between species and their risk of causing a ...
