Extraterrestrial chemistry with earthbound possibilities [Video]

“A lot of our water radiolysis research findings could be used in medical applications and medical simulations,” Barnes shares, offering the example of using high-energy radiation to treat cancer. “I once had a biochemistry professor say that humans are basically bags of water. So, other scientists are investigating how low-energy electrons produced in water affect our DNA molecules.”

She also says the team’s findings are applicable to environmental remediation efforts where wastewater is being treated with high-energy radiation, which produces large numbers of low-energy electrons that are assumed to be responsible for the destruction of hazardous chemicals. 

Back to space chemistry, in attempting to better understand prebiotic molecule synthesis, the researchers didn’t limit their efforts to mathematical modeling; they also tested their hypothesis by mimicking the conditions of space in the lab. They use an ultrahigh-vacuum chamber containing an ultrapure copper substrate that they can cool to ultralow temperatures, along …
