A new study published June 7 in the journal Scientific Reports found that space travel weakens the immune system by causing the abnormal activation of cells that suppress immune responses. Researchers from the University of California, San Francisco and the Stanford University School of Medicine arrived at this finding after exposing human blood samples to simulated weak gravity, or microgravity. They then used … Continue reading Researchers discover how space travel weakens astronauts’ immune systems
Scientists use nanoparticles as an alternative propulsion method for small spacecraft
Propellant is one of the most important things that any spacecraft needs to carry – without it, a spacecraft will be unable to move or change course. This is why spacecraft tend to carry a lot of it on board. Carrying propellant, however, brings its own set of problems. Not only is the chemical highly flammable, … Continue reading Scientists use nanoparticles as an alternative propulsion method for small spacecraft
Organic matter found in ancient meteorites may hold clues to understanding the birth of life on Earth
Chondritic meteorites that date back to the formation of the Solar System offer a window through which we can view the distant past. Researchers believe that organic matter trapped in these antediluvian space rocks can show us how life began on our planet, an article in Alpha Galileo reported. Furthermore, the University of Manchester (UoM) research team suggests that such … Continue reading Organic matter found in ancient meteorites may hold clues to understanding the birth of life on Earth
We’ve already begun trashing the moon: A summary of what’s been left up there
Humanity may not be living on the moon just yet, but that doesn’t mean we haven’t left a mark on its surface. Or marks, if you will – about 400,000 pounds of it. That number is the estimated, collective weight of all the human trash that’s accumulated on the face of Earth’s satellite. Shocking as … Continue reading We’ve already begun trashing the moon: A summary of what’s been left up there
