Phys.org / Dinosaurs may have originated 10 million years earlier than fossils show
Dinosaurs are among the most majestic and iconic animals to have ever walked on our planet. While they are now extinct, they are estimated to have inhabited Earth for over 165 million years.
Phys.org / Physicists achieve first-ever 'quadsqueezing' quantum interaction
Researchers at the University of Oxford have demonstrated a new type of quantum interaction using a single trapped ion. By creating and controlling increasingly complex forms of "squeezing" – including a fourth-order effect ...
Phys.org / Explosive evaporation unlocks new possibilities in 3D printing and chemical analysis
Water droplets might seem simple at first. But when nearing evaporation, a desperate power struggle of competing physical forces can emerge, with explosive effects. In a Proceedings of the National Academy of Sciences publication, ...
Phys.org / A better way to search for extraterrestrial intelligence
When you're looking for signs of extraterrestrial intelligence, it helps to know what you're looking for and to go about it in the most efficient way. But work so far has generally not done so, writes Benjamin Zuckerman, ...
Phys.org / AI tackles one of math's most brutal problems: Inverse PDEs
Penn Engineers have developed a new way to use AI to solve inverse partial differential equations (PDEs), a particularly challenging class of mathematical problems with broad implications for understanding the natural world.
Phys.org / Widespread genetic exchange in disease-causing parasites revealed
Mississippi State University biologist Matthew W. Brown is part of an international research team whose latest findings, published this spring in the Proceedings of the National Academy of Sciences, are reshaping scientific ...
Phys.org / Bigger, faster, but still outfoxed: How prey escape predators
Predators are typically larger, faster, and more powerful than the animals they hunt. Yet in nature, most attacks fail. A new study published in the Proceedings of the National Academy of Sciences, by researchers from the ...
Phys.org / How oak trees outwit their predators
Spring in the forest: Many insects, particularly caterpillars, hatch just when the trees' nutrient-rich leaves are still young and soft. This means they find a table laden with food and can start eating straight away. If ...
Phys.org / Mechanochemistry simplifies synthesis of challenging conductive organic molecules
Mechanochemistry is a growing field for chemical reactions that proceed in the solid state in the absence, or with minuscule amounts, of solvent added. For decades, solvents have been considered conventional for the progression ...
Phys.org / The way a cell fails to divide after copying its DNA can determine its fate
Cell division is one of the most fundamental and complex processes underpinning life. In human cells, thousands of molecules coordinate with one another in highly precise steps, all within a fraction of a second. But things ...
Phys.org / How photosynthetic bacteria pass light along: Two major energy pathways identified
RIKEN researchers have found out how light energy harvested by pigments besides chlorophyll is transferred to the molecular site where photosynthesis occurs in cyanobacteria. The work is published in the journal Plant and ...
Phys.org / Slower access, faster chemistry: Nanoreactor design improves catalysis by balancing molecular flow
A new study by a team at Tohoku University, published in Chemical Engineering Journal, has shown that more isn't always better when it comes to nanoscale chemical reactions. One might think that giving reactants completely ...
