Phys.org / Primordial halo simulations reveal how cosmic storms shaped the universe's first stars
Just a few hundred million years after the Big Bang, the universe was a dark and simple place. There were no galaxies like the Milky Way, no planets, and no heavy elements such as carbon or oxygen. Instead, vast clouds of ...
Phys.org / The Caspian Sea has lost an area nearly the size of Sicily: Human activities are a major reason why
The Caspian Sea, the largest inland body of water on Earth, is shrinking. Not fluctuating, not entering another natural cycle, but shrinking.
Phys.org / How solar wind forecasting will help define heliosphere's boundaries
Southwest Research Institute (SwRI) scientists are using a solar wind forecasting method combined with analytic and numerical heliosphere models to find out where the first plasma boundary of the outer heliosphere lies as ...
Phys.org / How cyanobacteria developed photosynthetic membranes over the course of evolution
A new study provides the first insights into how thylakoid membranes—the internal compartments where oxygen-producing photosynthesis takes place—emerged during evolution. By comparing the genomes of cyanobacteria with and ...
Phys.org / Leaf-based fluorescence test speeds search for plant gene-editing targets
Gene editing of plant DNA has the potential to produce crops with increased performance and resilience, but it can take a long time to achieve these gains. To shorten this process, scientists often use screening tools to ...
Phys.org / Mosquito-borne viruses avoid killing hosts by limiting protein output, study reveals
The increase in mosquito-borne virus infections is a growing public health concern. Diseases traditionally confined to tropical or subtropical regions, like dengue or West Nile virus, are expanding their geographic scope. ...
Phys.org / Algae microbots take aim at bladder cancer
Tiny algae-based robots guided by magnets could improve bladder cancer treatment by boosting delivery of chemotherapy drugs into tumors, researchers say.
Phys.org / A minimal model for how a cell takes shape from the inside
Researchers at the University of Twente and Utrecht University have packed rigid, rod-shaped particles into soft lipid containers the size of a living cell and watched the container and its contents reshape each other. The ...
Phys.org / Protein-tagging technology maps a hidden communication network between organs
The body's organs are in constant communication. Fat tissue tells the liver when to store or release energy, the immune system signals localized inflammation, and thousands of proteins carry these messages to organs throughout ...
Phys.org / Heat stress exposure climbed from 16% to 22% worldwide over 50 years, study shows
The number of people exposed to dangerous heat stress worldwide has risen sharply over the past half-century, propelled by climate change, according to a study released Monday as Europe sweltered through a punishing heat ...
Phys.org / Feeding data to AI to speed up drug discovery
Developing new medicines can require thousands of chemistry experiments to identify the right recipe for a safe, effective and ideally affordable drug.
Phys.org / Insects exhibit evidence of a daily body clock for humidity
In a novel experiment at the University of Cincinnati, researchers recently isolated kissing bugs, fruit flies, mosquitoes and spider beetles in a climate- and light-controlled environment and found that they responded predictably ...
