Osteopenia is a pathological process that affects human skeletal health not only on earth but also in long-time spaceflight.
To our knowledge, our results show for the first time that spaceflight can reduce the growth of tumor cells, and we also provide a new model for oncogenesis study.

Today's anniversary comes at a fraught time for American spaceflight.
This setback, and other challenges, make it likely that, in the UK, satellite launches will come some time before human spaceflight.

"The men and women we assign to these first flights are at the forefront of this exciting new time for human spaceflight," said Mark Geyer, director of NASA's Johnson Space Center in Houston, in a statement.
Riders on the rollercoaster, which has been named Galactica, will wear virtual reality (VR) headsets for the duration of the three-minute experience, with the digital images of spaceflight timed to coincide with the ride's twists and turns.
Matt Damon, in all his squat retroussé-nosed handsomeness, plays Mark Watney, a Nasa astronaut who in some future time of viable human spaceflight exploration is part of a team undertaking dull scientific research into the red dust and red rocks on Mars, earnestly decanting them into little plastic pots and exchanging good-natured walkie-talkie badinage with his team.
"Two American astronauts are expected to come back to Earth tomorrow tired and badly in need of shaves and showers but carrying with them the answer to one of the most important questions facing the whole United States program of space exploration," he wrote in a 1965 article about the Gemini 5 space mission, at the time the longest manned spaceflight.
