For the first time ever, DNA was successfully sequenced in microgravity as part of the Biomolecule Sequencer experiment performed by NASA astronaut Kate Rubins this weekend aboard the International Space Station. The ability to sequence the DNA of living organisms in space opens a whole new world of scientific and medical possibilities. Scientists consider it a game changer.

DNA, or deoxyribonucleic acid, contains the instructions each cell in an organism on Earth needs to live. These instructions are represented by the letters A, G, C and T, which stand for the four chemical bases of DNA, adenine, guanine, cytosine, and thymine. Both the number and arrangement of these bases differ among organisms, so their order, or sequence, can be used to identify a specific organism.

The Biomolecule Sequencer investigation moved us closer to this ability to sequence DNA in space by demonstrating, for the first time, that DNA sequencing is possible in an orbiting spacecraft.

Colonizing Mars may require humanity to tap into its inner bear.

Researchers are working on ways to induce a hibernation-like torpor state in astronauts — a breakthrough they say would slash costs and make the long journey to the Red Planet safer and far less taxing for crewmembers.

Such benefits could help lay the foundation for the first footsteps on Mars, and they’re essential to the establishment of a long-term human outpost there, project team members said. [Red Planet or Bust: 5 Crewed Mars Mission Ideas].

An international team of astronomers has just detected signals coming from almost 100 light years away, and they believe the signal is a strong candidate for extraterrestrial contact, according to a document circulated by Alexander Panov, a theorectical physicist at Lomonosov Moscow State University: “a strong signal in the direction of HD164595, a planet system in the constellation Hercules was detected on May 15, using the RATAN-600 radio telescope (below) in the Russian Republic of Karachay-Cherkessia.”

It’s an add-on for CRISPR.


Researchers have created a new genome editing technique called Target-AID, which induces point mutations instead of cutting DNA

Gene editing technology has fantastic potential, but there are remaining issues and questions over safety and specificity. The major contender is currently CRISPR-Cas9, but this induces a double stranded break in DNA which is a slightly riskier approach — particularly if it cuts in other locations too that you don’t want it to. Research teams across the world are both optimising and customising the CRISPR system; creating more accurate versions or versions that regulate gene expression as opposed to editing it. One such team has now built an add-on to CRISPR, Target-AID.

Tesla took Ludicrous Mode to new heights today. Some subtle wiring changes and a major battery upgrade improved mileage and gave the Model S enough oomph to go from 0 to 60 mph in 2.5 seconds—within fractions of seconds of Ferrari and Porsche models.

The extra performance is largely attributed to a larger battery. Its 100kWh is a 10 percent increase from the previous largest option, and increases total distance for some models by up to seven percent.

Of course it comes at a price. The Model S now costs as much as $134,000—and as always you need to be able to charge it.
