Phys.org / Why rainfall remains hard to predict in a warming world
A new study led by the University of Oxford and ETH Zurich reveals that a key part of the climate system—the large-scale wind patterns that determine where rain falls—can be underestimated by current climate models, helping ...
Phys.org / AI discovery reveals DNA isn't locked away in cells after all
Every cell in the human body squeezes over six feet of DNA into a minuscule speck invisible to the naked eye—like compressing a whole house into a single sugar cube. In order to fit in a cell and remain organized, DNA is ...
Phys.org / The battle of the sexes in the egg: How early nuclear rivalry helps embryos develop properly
The sperm and the egg cell's nuclei compete for size directly after fertilization and this is necessary for proper embryonic development. A mouse study with Kobe University participation finally gives meaning to a phenomenon ...
Phys.org / How cells decide when to react could shape future treatments for cancer and fibrosis
Scientists have discovered how cells decide when to respond to physical forces, potentially opening new avenues for tackling diseases such as cancer and fibrosis.
Phys.org / Radioactive imaging reveals ants' secret food networks
Researchers at the National Institutes for Quantum Science and Technology (QST) and the University of the Ryukyus have developed a new imaging method that makes it possible to see, in real time, how food is distributed and ...
Phys.org / 'Ruthless predator' of red tide plankton reveals unusual bioluminescence
Scientists at UC San Diego's Scripps Institution of Oceanography have uncovered new insights into the bioluminescence of a unique species of marine plankton that feeds on other plankton, including the harmful algae responsible ...
Phys.org / No brain required: This is how the single-celled Stentor learns
Scientists have known for more than a century that a single-celled organism with no nerve cells—much less a brain—can behave in ways that resemble learning. But those observations only went so far. How the organism did that ...
Phys.org / Ancient farming clues may finally expose where humanity's most important wheat first emerged
The exact origin of bread wheat (Triticum aestivum) is still a mystery, but researchers believe they are edging closer to the source of one of the most important food staples worldwide. Using genetic studies and ancient plant ...
Phys.org / How a free flow of information can amplify incorrect ideas
The idea that information should flow freely is deeply embedded in the design of social media. The assumption is that the more information is produced and shared, the better. However, simulations by a team of scientists including ...
Phys.org / Invisible fertility crisis: Chemicals and climate change threaten reproduction across species
The rise in infertility is not limited to humans, as environmental stressors are quietly undermining the reproductive potential of different forms of life. A recent review published in npj Emerging Contaminants investigated ...
Phys.org / Thinner than hair and stretchable like rubber, this new shield tackles a space-age problem in one layer
Shielding materials are essential in key modern industrial settings—such as spacecraft, nuclear power plants, semiconductor equipment, and advanced medical devices—to protect both equipment and personnel from electromagnetic ...
Phys.org / Atlantic Forest's top predator faces a hidden collapse, and protected areas are no longer enough
In addition to habitat loss and illegal hunting, the jaguar (Panthera onca) faces another threat that increases its risk of extinction in the South American Atlantic Forest: food scarcity. A study by Brazilian researchers ...
