For The First Time, DNA Has Been Edited With CRISPR in Space

Humans may not be able to burp properly in space, but we can now edit a genome. For the first time, astronauts aboard the International Space Station (ISS) have used CRISPR-Cas9 to edit the DNA of brewer’s yeast.

The goal wasn’t to create super space yeast. The astronauts were studying how DNA repair mechanisms work in space, so they snipped through strands of the fungus’s genetic code in a number of places to mimic radiation damage.

“The damage actually happens on the space station and the analysis also happens in space,” said Emily Gleason of miniPCR Bio, the company that designed the DNA lab aboard the ISS. “We want to understand if DNA repair methods are different in space than on Earth.”

An Astounding Amount of Water Has Been Discovered Beneath the Martian North Pole

Using ground-penetrating radar, scientists detected a massive reservoir of frozen water sandwiched by layers of sand beneath the northern polar ice cap on Mars. This reservoir contains so much ice that, if melted and brought to the surface, it would submerge the entire planet.

“This was a surprise even for us,” Stefano Nerozzi, the lead author of the new paper and a PhD student at the University of Texas at Austin, told Gizmodo in an email.

‘Like trying to build the USA in the middle of the Atlantic’: Elon Musk just dunked on Jeff Bezos’ vision to build floating space colonies

I agree with Bezos on this one.

Elon Musk dismissed Jeff Bezos’ plan of housing a trillion people in orbiting ‘O’Neill colonies,’ which resemble gargantuan spinning cylinders.

Space 2.0: Something’s Going to Happen, Something Wonderful

A review of Rod Pyle’s new book, Space 2.0, a tour de force of the “new space” phenomena packed with photos and details of the amazing people behind it. The book goes beyond Musk, Branson and Bezos and explains the origins of the science and engineering required to build an economy beyond Earth.
