[ad_1] Simulations of nuclear material in collisions leading to extreme conditions of density and temperature. Credit: The HADES collaboration. Collisions between neutron stars are fascinating cosmic events that lead to the formation of many chemical elements. Temperatures in these collisions are exponentially high, typically reaching hundreds of billions degrees Celsius. The HADES collaboration, a large … Read more

[ad_1] The diagram illustrates the structure of tiny bubbles, called liposomes, used to administer drugs. The blue spheres represent lipids, a kind of fat molecule, surrounding a central cavity containing magnetic nanoparticles (black) and the drug to be administered (in red). When the nanoparticles are heated, the drug can escape into the body. Credit: Massachusetts … Read more
[ad_1] Bring together As India arrived in lunar orbit this morning, bickering over who was going to lead NASA's next lander, Rocket Lab landed another hit and a Chinese satellite seemed to collapse. Rocket Lab: "Look at my mother, no hands" Rocket Lab continued its successful launches yesterday by sending four additional satellites into orbit … Read more
[ad_1] A proximity, rocky exoplanet may be just an ordinary rock without atmosphere – supporting a theory that planets orbiting small stars are more likely to lack atmosphere. Astronomers using NASA Spitzer telescope observed the planet, named LHS 3844b, while looking for signs of an atmosphere. Instead, they found indications that the planet is a … Read more

Kohnen station in Antarctica. Image credit: Sepp Kipfstuhl. Iron-60 (60Fe) is a radioactive isotope of iron. It is produced from pre-existing stable iron … Read more
[ad_1] (Newser) – Predicting earthquakes is almost impossible, but a new study is hailed as an important first step. Delivery: Large earthquakes are preceded by smaller ones, reports the Los Angeles Times. Researchers have used a new technique developed to detect "micro-tremors" that are undetectable, some of which have a magnitude of less than 2. … Read more
[ad_1] The Chandrayaan-2 Indian spacecraft has entered the moon's orbit, the US Space Agency said Tuesday. The Vikram lander of the unmanned spacecraft is expected to reach the lunar surface next month, making India an exclusive group of countries that have successfully landed on the moon. Chandrayaan will continue to circle the moon in a … Read more
