Phys.org / Microcrystals in bioluminescent fish scatter light like a prism
Approximately 75% of marine organisms are bioluminescent, with specialized light-emitting organs called photophores. They use the light they produce for various purposes, like attracting mates, luring prey, or confusing predators.
Phys.org / Low pH outside cells rewires transport network and displaces Golgi apparatus, study finds
A new study led by the Universidad Carlos III de Madrid (UC3M) describes the mechano-chemical mechanism by which the acidity of the cellular environment destabilizes microtubules, the "avenues" that organize internal cellular ...
Phys.org / Ancient DNA rewrites the story of a historical Sámi burial
A new study by the University of Turku and partners provides fresh insights into an individual buried near Lake Kitka in Kuusamo, Finland, at the turn of the 17th century. DNA and isotope analyses show that the individual, ...
Phys.org / Nearly 50 years of data reveal happiness gap for single parents
Single parents are less happy than parents with a partner, according to a comprehensive analysis of global studies spanning nearly 50 years of data. With the number of solo caregivers on the rise in many countries, scientists ...
Phys.org / Mercury's water ice may have been deposited by a larger, slower impactor than previously thought—in only one day
The source of the significant water ice deposits hidden in Mercury's polar regions has been a topic of debate among researchers. A new study, published in the Journal of Geophysical Research: Planets, suggests that these ...
Phys.org / What a toothless, two-legged crocodile cousin reveals about life before dinosaurs dominated
In the Triassic, the modern animals we know were just beginning to diversify into a menagerie of forms and body plans that rhyme with the lifestyles of extinct and living animals better known to the public, but nested in ...
Phys.org / Timing in early brain growth may explain why closely related mammals build strikingly different cortexes
The outer regions of the brain, the cortex, have specific layers of different cells—neurons—that are similarly ordered among all mammals, from tiny mouse brains to huge elephant brains. However, the proportions of different ...
Phys.org / Triply-eclipsing triple star system discovered with TESS
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a triply-eclipsing star system. The newfound system, designated TIC 295741342, consists of two sun-like stars in an eclipsing binary and ...
Phys.org / Imaginary-time technique speeds X-ray scattering simulations by 50-fold for extreme matter
Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have developed a new procedure, enabling them to speed up elaborate computer simulations that analyze matter under extreme conditions. In particular, this work ...
Phys.org / How did we learn which plants are safe to eat? Food scientists explain
Have you ever eaten a green potato, or a bunch of rhubarb leaves? Hopefully not, because these two plant parts can be toxic to humans. While they may seem edible, they contain chemicals that can make you seriously ill.
Phys.org / Ice may release more iron than climate models predict
Most people think of ice as frozen and lifeless, but research at Umeå University shows the opposite. A new study published in the Proceedings of the National Academy of Sciences demonstrates that ice actively speeds up the ...
Phys.org / Just 1.2 billion years after the Big Bang, galaxies were already shaped by where they lived
A large protocluster of galaxies that existed 12.6 billion years ago, first discovered with the Subaru Telescope, has been examined in detail using the James Webb Space Telescope (JWST). The study found that galaxies in crowded ...
