A new Northwestern University study discovered that spaceflight -- both aboard a space shuttle or the International Space Station (ISS) -- has a consistent effect on the gut microbiome.
A globally important ocean algae is mysteriously scarce in one of the most productive regions of the Atlantic Ocean, according to a new paper. A massive dataset has revealed patterns in the regions where Atlantic coccolithophores live, illuminating the inner workings of the ocean carbon cycle and raising new questions.
The Hall thruster is a propulsion system that is often used by spacecraft enaged in longer missions. A recent study by Andrey Shashkov and co-workers at the Moscow Institute of Physics and Technology, Russia has shown how the operating lives of these systems can be further extended; their work was recently published in EPJ D.
The rare isotope iron-60 is created in massive stellar explosions. Only a very small amount of this isotope reaches the earth from distant stars. Now, a research team with significant involvement from the Technical University of Munich (TUM) has discovered iron-60 in Antarctic snow for the first time. The scientists suggest that the iron isotope comes from the interstellar neighborhood.
For the first time scientists have been able to reconstruct the chemical composition of rainwater from 300-million-year-old minerals, allowing them to unpick some of the history of Brittany and Western France since the rain fell in the late Carboniferous period, just before the time of the dinosaurs. The results point to the area being mountainous and originally located close to the Equator. This work is presented at the Goldschmidt Geochemistry congress in Barcelona.
Japanese researchers show how a holographic tabletop experiment can be used to simulate the physics of a black hole. This work may lead the way to a more complete theory of quantum gravity that harmonizes quantum mechanics and relativity.
A new study of conditions on Mars indicates that the climate 3 to 4 billion years ago was warm enough to provoke substantial rainstorms and flowing water, followed by a longer cold period where the water froze. This may have implications on the conditions for the development of life on Mars
An international team of Russian and Belgian researchers, including scientists from HSE University, has found out that space travel has a significant impact on the brain: they discovered that cosmonauts demonstrate changes in brain connectivity related to perception and movement.
A new case study demonstrates the steps being taken by the US National Aeronautics and Space Agency (NASA) to make it easier for small businesses and entrepreneurs to understand its needs and do business with it.
Lithium fluoride crystals have recently been used to register the tracks of nuclear particles. Physicists from the Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow have just demonstrated that these crystals are also ideal for detecting tracks of high-energy ions of elements even as heavy as iron.
