Phys.org / Ants defend plants from herbivores, but can hinder pollination by bees
Around 4,000 plant species from different parts of the world secrete nectar outside their flowers, such as on their stems or leaves, through secretory glands known as extrafloral nectaries. Unlike floral nectar, extrafloral ...
Phys.org / Porous radical organic framework improves lithium-sulfur batteries
A team led by Prof. Yan Lu, HZB, and Prof. Arne Thomas, Technical University of Berlin, has developed a material that enhances the capacity and stability of lithium-sulfur batteries. The material is based on polymers that ...
Phys.org / Provenance study shows 19th century looted 'Incan mummy' was actually an Aymara man
In a recent study, Dr. Claudine Abegg and her colleagues analyzed the remains of a mummified cranium housed in the collections of the Museum of Cantonal Archaeology and History of Lausanne.
Phys.org / Is dark energy evolving? Astrophysicists consider the possibilities
Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe's greatest mysteries. The most widely accepted theory currently suggests that dark energy is ...
Phys.org / Scientists engineer plants to double carbon uptake ability and produce more seeds and lipids
Typically, plants rely on the Calvin-Benson-Bassham (CBB) cycle to convert carbon dioxide in the atmosphere to usable organic matter for growth. Although this cycle is the main pathway for carbon fixation in all plants on ...
Phys.org / Observations investigate the nature of a newly discovered odd radio circle
Astronomers from Ruhr University Bochum in Germany and elsewhere have conducted radio spectropolarimetric observations of a recently identified odd radio circle designated ORC J0356–4216. Results of the observational campaign, ...
Phys.org / How mice extend short-range ultrasound for public announcements
Mice often communicate in ultrasound, which is so high-pitched that it's beyond human hearing. Because these sounds don't travel very far, it was thought that they were only used for private, close-up conversations. New research ...
Phys.org / The sound of crying babies makes our faces hotter, according to new research
Hearing a baby cry can trigger a range of responses in adults, such as sympathy, anxiety and a strong urge to help. However, new research suggests that a deeper physical reaction is also occurring. A baby's cry, particularly ...
Phys.org / The oldest mummies in the world may hail from southeastern Asia and date back 12,000 years
Scientists have discovered what's thought to be the oldest known mummies in the world in southeastern Asia dating back up to 12,000 years.
Phys.org / The new engine of voting: Out-party hostility outpaces in-party loyalty across established democracies
A new study led by Professor Diego Garzia of the University of Lausanne, published in Public Opinion Quarterly, reveals a major shift in electoral motivation. In many Western democracies, voters are now more driven by opposition ...
Phys.org / Inquiry into the history of science shows an early 'inherence' bias
Early scientific theories—such as those explaining basic phenomena like gravity, burning, and the movement of molecules in water—centered on presumed inherent properties rather than external factors, thereby misleading ...
Phys.org / Reference-quality genome assembly created for widely used RPE-1 human cell line
A research team led by Professor Simona Giunta at the University of Rome La Sapienza has produced the first reference-quality genome assembly of an experimentally relevant human cell line, the widely used retinal pigment ...
