Astronauts face many challenges to their health, due to the exceptional conditions of spaceflight. Among these are a variety of infectious microbes that can attack their suppressed immune systems.

Now, in the first study of its kind, Cheryl Nickerson, lead author Jennifer Barrila and their colleagues describe the infection of human cells by the intestinal pathogen Salmonella Typhimurium during spaceflight. They show how the microgravity environment of spaceflight changes the molecular profile of human intestinal cells and how these expression patterns are further changed in response to infection. In another first, the researchers were also able to detect molecular changes in the bacterial pathogen while inside the infected host cells.

The results offer fresh insights into the infection process and may lead to novel methods for combatting invasive pathogens during spaceflight and under less exotic conditions here on earth.

How can you possibly use simulations to reconstruct the history of the entire universe using only a small sample of galaxy observations? Through big data, that’s how.

Theoretically, we understand a lot of the physics of the history and evolution of the universe. We know that the universe used to be a lot smaller, denser, and hotter in the past. We know that its expansion is accelerating today. We know that the universe is made of very different things, including galaxies (which we can see) and dark matter (which we can’t).

We know that the largest structures in the universe have evolved slowly over time, starting as just small seeds and building up over billions of years through gravitational attraction.

But it’s not otaku homes the developer is hoping for these to appear in.

Astronomers have detected the best place and time to live in the Milky Way, in a recent study published in the journal Astronomy and Astrophysics.

More than six billion years ago, the outskirts of the Milky Way were the safest places for the development of possible life forms, sheltered from the most violent explosions in the universe, that is, the gamma-ray bursts and supernovae.

Scientists have struggled to formulate a universal definition of life. Is it possible they don’t need one?

SpaceX’s Starship is powered by methane. Its Falcon 9 runs on highly refined kerosene known as RP-1.

But if a new tweet means anything, SpaceX CEO Elon Musk already has his eyes set on a much higher-tech rocket fuel: antimatter.

In a reply to a post about antimatter rockets — hypothetical spacecraft that would be powered by antimatter — Musk tweeted just two words: “Ultimately, yes.”
