For The First Time Ever, CRISPR Gene Editing Was Used in Humans. So What’s Next?

Posted by in categories: bioengineering, biotech/medical, genetics, space

  • With Chinese scientists announcing that they have tested CRISPR on a human for the first time, the U.S. must decide soon whether it will be a leader or a follower in advancing the tech.
  • While gene editing technology could be used in nefarious ways, it could also cure diseases and improve millions of lives, but we won’t know how effective it is until we begin human trials.

While the middle part of the 20th century saw the world’s superpowers racing to explore space, the first global competition of this century is being set in a much smaller arena: our DNA.

Russia thinks microorganisms may be living outside the space station

Posted by in category: space

May 26 (UPI) — Officials with Russia’s space agency, Roscosmos, say their scientists have identified plankton and other microorganisms among dust samples collected from the outside of the International Space Station.

“The micrometeorites and comet dust that settle on the ISS surface may contain biogenic substance of extra-terrestrial origin in its natural form,” Roscosmos officials said in a news release. “The ISS surface is possibly a unique and easily available collector and keeper of comet substance and, possibly, of biomaterial of extra-terrestrial origin.”

NASA officials said they couldn’t confirm the story.

Near-Term Interstellar Probes: Some Gentle Suggestions

Posted by in categories: innovation, space

A bit of every speculative propulsion system.


When Greg Matloff’s “Solar Sail Starships: Clipper Ships of the Galaxy” appeared in JBIS in 1981, the science fictional treatments of interstellar sails I had been reading suddenly took on scientific plausibility. Later, I would read Robert Forward’s work, and realize that an interstellar community was growing in space agencies, universities and the pages of journals. Since those days, Matloff’s contributions to the field have kept coming at a prodigious rate, with valuable papers and books exploring not only how we might reach the stars but what we can do in our own Solar System to ensure a bright future for humanity. In today’s essay, Greg looks at interstellar propulsion candidates and ponders the context provided by Breakthrough Starshot, which envisions small sailcraft moving at 20 percent of the speed of light, bound for Proxima Centauri. What can we learn from the effort, and what alternatives should we consider as we ponder the conundrum of interstellar propulsion?

NASA Just Fast-Tracked Its Mission to Explore a $10,000 Quadrillion Metal Asteroid

Posted by in categories: economics, space

The science community just figured out why we wont actually be doing space mining, until capitalism is no longer a factor anyways.


It might have just pushed back its manned mission to Mars, but NASA just fast-tracked a planned journey to 16 Psyche — an asteroid made almost entirely of nickel-iron metal.

Estimated to contain $10,000 quadrillion in iron alone, if we could somehow mine Psyche’s minerals and bring them back to Earth, it would collapse our comparatively puny global economy of $78 trillion many times over. Fortunately for the economic stability of our planet, NASA plans on looking but not extracting.

For The First Time, Physicists Have Observed a Giant Magnetic ‘Bridge’ Between Galaxies

Posted by in categories: physics, space

For the first time, scientists have detected evidence of a magnetic field that’s associated with the vast intergalactic ‘bridge’ that links our two nearest galactic neighbours.

Known as the Magellanic Bridge, the bridge is a huge stream of neutral gas that stretches some 75,000 light-years between our two neighbouring galaxies, the Large and Small Magellanic Clouds (LMC and SMC). Although researchers had predicted it was there, this is the first observation of its magnetic field, and it could help us understand how these vast bridges come to be.

“There were hints that this magnetic field might exist, but no one had observed it until now,” said lead researcher, Jane Kaczmarek from the University of Sydney.
