Phys.org / Dinos hatched eggs less efficiently than modern birds, researchers show
What do we really know about how oviraptors—bird-like but flightless dinosaurs—hatched their eggs? Did they use environmental heat, like crocodiles, or body heat from an adult, like birds? In a new Frontiers in Ecology ...
Phys.org / Bull sharks form social relationships with specific 'friends,' research reveals
Sharks are often viewed as solitary, but a new study—carried out on the Shark Reef Marine Reserve in Fiji—has found that rather than mixing at random, bull sharks have "active social preferences" and choose their social ...
Phys.org / Ryugu asteroid samples contain all DNA and RNA building blocks, bolstering origin-of-life theories
All the essential ingredients to make the DNA and RNA underpinning life on Earth have been discovered in samples collected from the asteroid Ryugu, scientists said Monday.
Phys.org / Extremely rare second-generation star discovered inside ancient relic dwarf galaxy
Discovered in the Pictor II dwarf galaxy, star PicII-503 has an extreme deficiency in iron—less than 1/40,000th of the sun. This signature makes it the clearest example of a star within a primordial system that preserves ...
Phys.org / Do political social media ads influence the outcome of elections?
Social media platforms, such as Facebook, Instagram and X, are accessed daily by millions of people worldwide. In the weeks or months leading up to elections, many political parties use social media platforms as part of their ...
Phys.org / Why sugar breakdown matters beyond energy—new insights into how it makes cells move
It has long been known that our bodies derive energy from sugar. Researchers at RPTU University Kaiserslautern-Landau have now discovered that sugar breakdown produces an intermediate product that is also crucial for the ...
Phys.org / Amazonian chocolate: Combining cocoa clones with different post-harvest processes balances flavor and nutritional value
Chocolate produced in the Amazon is internationally recognized for its unique flavor. A study by researchers at São Paulo State University (UNESP) in Brazil has shown that it could be even more valuable. The analysis indicates ...
Phys.org / A galaxy next door is transforming, and astronomers can see it happening
The Small Magellanic Cloud (SMC) is one of the Milky Way's closest galactic neighbors—a small, gas-rich galaxy visible to the naked eye from the southern hemisphere, and bound to our galaxy by gravity, alongside its companion, ...
Phys.org / High-resolution electron microscopy sheds light on the cellular responses to stress
An international team led by researchers from the University Medical Center Göttingen (UMG), Germany, has used advanced electron microscopy technologies to capture key cellular mechanisms of stress resistance with near-atomic ...
Phys.org / Milk-derived nanoparticles may enable physicians to target aggressive bile duct cancer
Mayo Clinic researchers have developed a promising new way to deliver treatment directly to cholangiocarcinoma tumors, a rare and aggressive bile duct cancer with limited treatment options, using milk-derived nanoparticles ...
Phys.org / Q&A: Reevaluating reaction rates to better understand the stars
Thermonuclear reaction rates power the models that explain how stars live, explode and create the elements. A new study co-authored by NC State faculty member Richard Longland provides a comprehensive, statistically grounded ...
Phys.org / A clear roadmap for engineering combs of light
Optical frequency combs—laser sources that emit evenly spaced colors of light—are foundational, ubiquitous tools for precision measurement, found in optical clocks, gas-sensing spectrometers, and instruments that detect ...
