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 / 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 / Polymer strategy boosts lithium battery safety and performance by making plasticizers compatible
The performance and safety profile of lithium batteries has improved immensely over the years, but new technologies are constantly demanding even better performance and increased safety demands due to higher energy densities. ...
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 ...
Dialog / New fossil salamander species related to the famous axolotl is discovered in Mexico
The Mexican axolotl (Ambystoma mexicanum) is famous because adults look like overgrown babies, or tadpoles, retaining juvenile features as adults and capable of remarkable regeneration of lost limbs or tails. New studies ...
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 / Divers may think they protect reefs, but one unseen habit is taking a steady toll
Research at the University of Sydney has found that scuba-diving tourism—widely promoted as a sustainable way to experience coral reefs—is causing frequent and often hidden damage to fragile marine ecosystems.
Phys.org / Five-tea comparison reveals kombucha's biological properties depend on starting point
Over the past few years, kombucha has become one of the world's most popular fermented beverages. While most consumers focus primarily on its taste, scientists are increasingly analyzing its chemical composition and potential ...
Phys.org / How homing pigeons keep navigation simple when winging their way home together
When it comes to flocking together, homing pigeons use a simple strategy to find better ways home, according to a recent report. The study, published in the journal eLife, suggests that homing pigeons use simple route averaging ...
Phys.org / Teaching thermodynamic laws to AI unlocks a polymer modeling challenge
For more than half a century, materials scientists have struggled with how to simulate the complexity of polymer materials. An individual chain can comprise tens of thousands of atoms, a melt or composite contains billions, ...
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 / Researchers capture inception of hydrogen-uranium reaction for the first time
When hydrogen gas interacts with uranium metal, the combination creates a chemically reactive powder and a runaway reaction that is difficult to stop. The result can impact the safety and lifespan of technology critical for ...
