Mark Zuckerberg was on Facebook last night conducting his regular Townhall Q&As, with a few not-so-regular people including Stephen Hawking and Arnold Schwarzenegger.
Of the celebrity cast, Hawking was the only one who diverted the social media titan’s attention to science, asking him:

Last year, Google began experimenting with hardware-based schemes for user-authentication, while Apple added two factor authentication to iCloud and Apple ID users. They began sending a verification code to users via a mobile number registered in advance.
Security pundits know that two factor authentication is more secure than simple passwords. As a refresher, “Factors” are typically described like this:
The Google project may be just another method of factor #2. In fact, because it is small (easily misplaced or stolen), it simplifies but does not improve on security. I suggest a radical and reliable method of authentication. It’s not new and it’s not my idea…

“Let’s post our credit card numbers and even those pesky CSV codes on the back. (Better yet, let’s just do away with credit cards altogether because, at the end of that day, it’s just a bank taking on the risk that you’ll pay back a loan.) Let’s post our social security numbers and our driver’s licenses. Let’s post everything. Overnight, the incentives to steal your data are wiped off the face of the earth. The dark databases are worth zero.”
Last year, my personal credit cards and banks were breached five times. Last week, another personal breach. Each time, I was informed by email and snail mail, a new credit card or bank account was issued, and I bought more monitoring for my credit or, in the case of one of the breaches, the company that was breached bought additional monitoring. About the fourth time, I started wondering why our industry doesn’t do something else. The traditional IT security model is dead, but we just keep propping up the body. Hope has become our strategy in the cyber security war. Read more
If you think asteroids are rare, it’s only because they’re so small and dark and hard to see. An eye-opening new video (above) shows what the night sky would look like if we could see the near-Earth asteroids astronomers have discovered — it’s quite a swarm.
We have no choice BUT to become an interstellar species if we want to survive, even into the near future.
Ours is a world of static objects, cut, cast, or forged for specific tasks. But let’s say you opened an Ikea box, and the desk inside assembled itself. Or your water pipes shrank as the pressure decreased: no more weak showers, less wasted water. This is the 4D-printed future, and labs are already striving to make it a reality.
The tech builds on 3-D printing—with the added fourth dimension of time, across which objects transform. Skylar Tibbits, founder of MIT’s Self-Assembly Lab, coined the term “4D printing” in a 2013 TED Talk and showed how a straight plastic strand folded into the letters M, I, T when dropped in water.
