Pregnancy in space: Studying stem cells in zero gravity may determine whether it's safe
Wednesday, 07 September 2022 12:39
Space is a hostile, extreme environment. It's only a matter of time before ordinary people are exposed to this environment, either by engaging in space tourism or by joining self-sustaining colonies far away from Earth.
To this end, there needs to be a much better understanding of how the environmental dangers of space will affect the biology of our cells, tissues, organs, and cognition. Crucially for future space colonies, we need to know whether we can easily reproduce in environments other than those found on Earth.
The effects of radiation on our cells, producing DNA damage, are well documented. What's less clear is how lower levels of gravity, what scientists call microgravity, will affect the mechanisms and rhythms taking place within our cells.
Scientists are only just beginning to investigate how activity in our cells might be affected by exposure to microgravity. Crucially, experiments on embryonic stem cells, and models of how embryos develop in their first few weeks in space, will help us determine whether it's possible for humans to produce offspring in the extraplanetary colonies of the future.

Th Gamma rays from neighboring galaxy related to millisecond pulsars
Wednesday, 07 September 2022 09:12
A team of researchers, including UvA physicists and astronomers, has studied gamma rays caused by the Sagittarius Dwarf, a small neighbouring galaxy of our Milky Way. They showed that all the observed gamma radiation can be explained by millisecond pulsars, and can therefore not be interpreted as a smoking gun signature for the presence of dark matter. The results were published in Nature Astron Antenna enables advanced satellite communications testing

On the rooftop of an MIT Lincoln Laboratory building sits a 38-foot-wide dome-shaped radio antenna enclosure, or radome. Inside the climate-controlled environment, shielded from the New England weather, a steel structure supports a 20,000-pound, 20-foot diameter satellite communications (SATCOM) antenna. The antenna - called the Multi-Band Test Terminal (MBTT) - can rotate 15 degrees per second, Back in Bordeaux with the A310 ZERO G

By using radio telescopes to study sun-like stars in their death throes, scientists hope to reveal important information about the origin of life-enabling chemicals in the universe. The National Science Foundation is awarding a $339,362 Astronomy and Astrophysics Research Grant to a team led by Rochester Institute of Technology Professor Joel Kastner to conduct such a study.
Planetary nebu Magnetic skyrmions - ready for take-off?
Wednesday, 07 September 2022 09:12
Magnetic skyrmions are extremely small and stable swirls of magnetization, often referred to as 'topological quasi-particles' since an emerging stability embraces this spin ensemble. As such, skyrmions can be manipulated while retaining their shape. In ferromagnetic thin films, they can conveniently be created with an electrical current pulse or, even faster, with a laser pulse ? albeit, so far, Astronomers show massive stars can steal Jupiter-sized planets

Jupiter-sized planets can be stolen or captured by massive stars in the densely populated stellar nurseries where most stars are born, a new study has found.
Researchers from the University of Sheffield have proposed a novel explanation for the recently discovered B-star Exoplanet Abundance STudy (BEAST) planets. These are Jupiter-like planets at large distances (hundreds of times the dist
