Scientists Discover Exposed Bacteria Can Survive in Space for Years

Framed by an infinite backdrop of dark, lifeless space, a robotic arm on the International Space Station in 2015 mounted a box of exposed microbes on a handrail 250 miles above Earth. The hearty bacteria had no protection from an onslaught of cosmic ultraviolet, gamma, and x-rays. Back on Earth, scientists wondered whether the germs might survive these conditions for up to three years, the length of the experiment, and if they did, what the results might tell the researchers about the ability of life to travel between planets.

3D-printed bacteria ink could be used to treat burns

In a new study published today in Science Advances, researchers present a 3D-printable ink that contains bacteria and they say that depending on what species of bacteria it holds, the ink stands to have a number of useful applications. “Printing using bacteria-containing hydrogels has enormous potential, as there is such a wide range of useful bacteria out there,” Patrick Rühs, an author of the study, said in a statement.

Are Vitamin Supplements Killing Our Gut Bacteria?

We consume all sorts of things before really knowing how they’re going to affect us, including probiotics and dietary supplements. But given how preliminary our understanding of our gut bacteria is, it’s very likely that some supplements can work in direct opposition of others. For instance, vitamin A might kill a bacteria hypothesized to promote childhood growth.
