Phys.org / Water isotopes reveal early drought signals in Central Amazon rainfall
The historic droughts of 2023 and 2024 in the Amazon reduced river flows and altered the region's rainfall composition. Daily monitoring in Manaus, the capital of the Brazilian state of Amazonas, revealed these changes through ...
Phys.org / Kids' brains are built for distraction. Sometimes that's a good thing.
Parents often learn the hard way that to make it anywhere on time, they should calculate how much time they think they need to get ready—and double it.
Phys.org / Rewetting peatlands may curb warming-driven CO₂ emissions
Peatlands store large amounts of carbon. However, when they are drained, they can become substantial sources of the greenhouse gas carbon dioxide (CO₂).
Phys.org / Northern map turtles leave Lake Erie before algal blooms peak, tracking finds
Harmful algal blooms pose serious threats to people, animals and the environment. The University of Toledo's Dr. Jeanine Refsnider counts it as a positive discovery that northern map turtles tend to steer clear, as she and ...
Phys.org / AI pinpoints when fish reach their thermal limit
Researchers have developed an AI-based system that automatically and objectively detects the moment when fish experience loss of equilibrium (LOE) due to temperature stress. The system combines DeepLabCut, a deep-learning ...
Phys.org / Scavenging linked to virus variety in wild birds
The scavenging behavior of many wild birds plays an important role in the type, number and variety of viruses they have, a new University of Otago–Ōtākou Whakaihu Waka-led study has found.
Phys.org / From flower to fruit: A tug-of-war between growing tissues
Unlike an animal cell, a plant cell can't crawl or migrate. It's locked inside a rigid wall, cemented to its neighbors for life. A cell born at the center of a young fruit will still be there when that fruit ripens.
Phys.org / First PLP-dependent enzyme that influences bacterial protein production discovered
Researchers from the Singapore-MIT Alliance for Research & Technology's (SMART) Antimicrobial Resistance (AMR) interdisciplinary research group, alongside collaborators from Massachusetts Institute of Technology (MIT), Nanyang ...
Phys.org / A wandering black hole caught feeding on the run
Astronomers have found the first direct evidence that a wandering black hole can feed itself by dragging gas along in its wake as it moves through its galaxy. It's the first direct evidence of an accretion channel long predicted ...
Phys.org / The surprising place where giant dinosaurs incubated their eggs
Finding a fossilized dinosaur egg is exceptionally rare, but finding a stash of more than 250 shell fragments in the chilly southern reaches of the planet is even more surprising. The discoveries come from southernmost Patagonia ...
Phys.org / Ancient bones reveal that cannibalism took different forms in Neolithic Spain
Cannibalism was sometimes on the Neolithic menu, as numerous archaeological discoveries have revealed. But while ancient human bones show the practice took place, far less evidence exists about the forms it may have taken ...
Phys.org / The 'costly son' hypothesis: Why bigger sons may make births riskier across species
A new comparative review, published in The Anatomical Record, examines factors that may lead to birth complications among humans and other mammals. The study suggests that fetal sex may play an important role in risky births ...
