US officials canceled NASA’s ambitious Mars Sample Return program, leaving potential evidence of ancient life sitting on Mars. Could China beat them to it?

It’s weird to think there was a time when people didn’t logically assume that inhaling cigarette smoke several times a day didn’t have some kind of native effect on the body. Some doctors even recommended smoking at one point. Now we know smoking causes a range of issues, like cancer and emphysema. But those are the broad implications that affect everyone. According to new research, cigarettes can impact our reproductive organs, but those impacts may affect men and women differently. A study published in Frontiers in Toxicology by researchers at the Universities of Nottingham and Sheffield looked at how cigarette smoke extract affected male and female mice over twelve weeks. The team found that while tobacco smoke wrecks reproductive health across the board, regardless of whatever factors you threw in front of it, it does operate through distinct biological routes depending on sex.
