Last year August, Stephen Hawking announced he had been working with Malcom Perry and Andrew Strominger on a solution to the black hole information loss problem, and they were closing in on a solution. But little was explained other than that this solution rests on a symmetry group by name of supertranslations.
Elon Musk’s vision of the Hyperloop — a lightning-fast transportation system that would shuttle passengers at speeds nearing 700-mph using low pressure tubes and air compressors — is slowly coming to fruition in the Nevada desert.
In fact, the first ever Hyperloop tubes are neatly lined up in a ditch, waiting to be assembled and then later tested by Hyperloop Technologies at a site in North Las Vegas.
Now this is something you don’t hear every day.
Or week.
Or year.
Or…
We shall see. We shall see. wink
For three decades, humans have searched for signs of intelligent life beyond Earth, and yet we’ve only sampled a tiny drop of our vast cosmic ocean. If we’re ever to find a radio-hot, spacefaring civilization, we need to know where to point our telescopes.
But the answer may be simpler than we thought. According to a new study, there are roughly 150 brilliant patches of space that deserve our attention.
They’re called globular clusters, an evocative term for ancient, gravitationally-bound regions of space that can pack a whopping million stars per hundred cubic light years. Once thought to be uninhabitable, new research by Rosanne Di Stefano of the Smithsonian Astrophysical Observatory and Alak Ray of the Tata Institute in Mumbai suggests that globular clusters may, in fact, be the ideal places for advanced civilizations to flourish.
In a landmark study, researchers have used gene editing system CRISPR-Cas9 to treat a model of Duchenne muscular dystrophy in mice
Proof of concept for future human treatment
While safety is still a concern, the use of gene editing methods to treat disease in adult patients isn’t controversial. Altering embryos is entirely different to treating an adult, predominantly as the implications are profound and an embryo obviously cannot give permission.
NASA recently provided $10 million in funding to Ad Astra Rocket Company of Texas for further development of its Variable Specific Impulse Magnetoplasma Rocket (VASIMR), an electromagnetic thruster capable of propelling a spaceship to Mars in just 39 days. NASA’s funding was part of the “12 Next Space Technologies for Exploration Partnership.” Ad Astra’s rocket will travel ten times faster than today’s chemical rockets while using one-tenth the amount of fuel.
The VASIMR system would cut the trip to Mars by months according to Franklin Chang Diaz, a former MIT student, NASA astronaut, and now CEO of Ad Astra.
According to Diaz, “this is like no other rocket that you may have seen in the past. It is a plasma rocket. The VASIMR Rocket is not used for launching things; it is used for things already in orbit. This is called “in-space propulsion.”
A milestone in the history of cybersecurity?
Cyberattacks on the power grid just became a much more real threat, according to researchers.
If you thought the Kepler spacecraft’s glory days were over, think again. Today at the 227th meeting of the American Astronomical Society, astronomers announced a whopping 234 new exoplanet candidates discovered by Kepler in 2014. The best part? All of them are just tens of light years away.
The deluge of planetary candidates are distributed among 208 star systems, which means we have the honor of welcoming many new multi-planet systems to our cosmic neighborhood. While these candidates aren’t confirmed yet, there’s a good chance most of them will be, according to Andrew Vanderburg of the Harvard Center for Astrophysics, who presented the findings today. All 234 were found during the first year of the K2 mission, which is scanning stars across the plane of our solar system, moving from one field of view to the next.
Add these K2 planets to the 4,600+ candidate worlds (1,918 confirmed planets) discovered during Kepler’s original mission, and it’s fair to say this little telescope has become one hell of a planet hunter.
Walls and floors can seriously limit the range of your wireless network, but the WiFi Alliance thinks they’ve come up with a fix. Their new 802.11ah standard aims to deliver superior penetration and power savings to boot.
How will 802.11ah do that? By operating in the unlicensed 900MHz spectrum. Today’s WiFi gear operates at either 2.4GHz or 5GHz. Their higher frequencies make it harder for the signals to maintain their strength as they pass through obstructions. That’s one reason Google wants you to pretty up your OnHub router: so that you stick it somewhere out in the open where walls won’t get in the way.
Way down at 900MHz, though, things like walls, floors, and doors won’t be as much of a problem. According to the WiFi Alliance, 802.11ah will also achieve nearly double the range of current standards. There’s another bonus, too. Because the signal doesn’t degrade as much when it passes through objects, devices don’t consume as much power while sending and receiving data.
