Phys.org / How plants respond to changing environments for better reproductive success
Once a seed germinates, it is committed to one location. Plants are sessile—stuck where they started out—forced to cope with whatever conditions arrive next. The only way out of trouble is to rebuild themselves in place.
Phys.org / Shipping regulations to reduce pollution may have exacerbated Great Barrier Reef bleaching
Rising ocean temperatures have been implicated in mass coral bleaching events affecting the Great Barrier Reef (GBR). These events have been increasingly frequent, with major events occurring in 2016, 2017, 2020, 2022, 2024, ...
Phys.org / First carbon-enhanced metal-poor stars discovered in Milky Way's companion
Using the Baryons Oscillation Spectroscopic Survey (BOSS) spectrograph, astronomers have discovered five new carbon-enhanced metal-poor stars in the Large Magellanic Cloud (LMC). This is the first time such stars have been ...
Phys.org / Collective intelligence: How to incentivize problem solving in groups
When a crowd gets something right, like guessing how many beans are in a jar, forecasting an election, or solving a difficult scientific problem, it's tempting to credit the sharpest individual in the room. But new research ...
Phys.org / Cleaner ship fuel changed clouds, but not their climate balance
To reduce air pollution associated with ocean transport, the International Maritime Organization tightened restrictions on sulfur content in ship fuel, resulting in an 80% reduction in emissions by 2020. That shift created ...
Phys.org / Jurassic amphibian with a projectile tongue named as a new species
A new species of amphibian that lived 150 million years ago has been discovered in Portugal. The tiny animal was one of the earliest species belonging to a mysterious group of amphibians that lived from the time of the dinosaurs ...
Medical Xpress / Bioelectronic wristband offers continuous, objective, real-time stress monitoring
Researchers at the University of California, Irvine have developed a multimodal, bioelectronic wrist-worn device for objective, continuous, real-time monitoring of stress. The Smart Quantitative and Comprehensive Stress Assessor ...
Phys.org / King's Trough: How a shifting plate boundary and hot mantle material shaped an Atlantic mega-canyon
The King's Trough Complex is a several-hundred-kilometer-long, canyon-like system of trenches on the North Atlantic seafloor. Its formation was long thought to be the result of simple stretching of the oceanic crust. An international ...
Medical Xpress / Experimental immunotherapy clears harmful artery cells, reducing plaque in mice
Scientists have designed an immunotherapy that reduces plaque in the arteries of mice, presenting a possible new treatment strategy against heart disease. The antibody-based therapy could complement traditional methods of ...
Phys.org / Refractive-index microscope measures a sample's optical properties with pinpoint accuracy
By combining two fundamentally different microscopy techniques, researchers can now measure the optical properties of a sample with pinpoint accuracy. The original goal was to investigate biological samples on a molecular ...
Phys.org / Crosstalk inside cells helps pathogens evade drugs, study finds
Biologists have uncovered a new mode of communication inside cells that helps bacterial pathogens learn how to evade drugs. Their findings, published in the journal Nature Communications, describe how these mechanisms drive ...
Phys.org / Svalbard polar bears show improved fat reserves despite sea ice loss
The body conditions of polar bear (Ursus maritimus) populations around the Norwegian island of Svalbard have improved despite sea ice losses, according to new findings. The findings differ from previously published observations ...
