Hacked 3D printers could commit industrial sabotage

Posted by in categories: 3D printing, food, transportation

3D printers can churn out toys, clothing and even food. But the technology also shows potential for use in industrial sabotage, researchers warn.

Imagine a car maker using 3D printers to manufacture components, only to have the parts contain defects that are undetectable until it’s too late.

A hacker with access to the 3D printers could make that happen, a team of researchers wrote in a recent paper. This could result in a “devastating impact” for users and lead to product recalls and lawsuits, said New York University professor Nikhil Gupta, the lead author of the paper.

Coming soon: 3D printing satellites in outer space

Posted by in categories: 3D printing, satellites

3D printing satellites in outer space might sound like the stuff of sci-fi movies, but that’s exactly where the aerospace industry’s biggest players are heading.

More than just a cool gimmick, 3D printing could help save companies money when launching satellites into space by building parts of them there.

“If you think of challenges in getting a satellite into orbit, if you think of major antennas, the fold out antennas we have, the ability to print something in space and deploy it from space is really interesting,” Andy Anderson, deputy chief technology officer at Airbus, told CNBC in an interview at the Farnborough air show on Monday.

Using 3D Printing to Explain the Mind-Bending Optical Illusion That Broke the Internet

Posted by in categories: 3D printing, internet

Last week an entry for the Best Illusion of the Year Contest called the Ambiguous Cylinder Illusion from Japan’s Kokichi Sugihara confused and delighted viewers all over the world. The video showed six plastic cylinders stuck together, and when they were placed in front of a mirror they inexplicably became squares. When the cylinders were rotated, the reflection finally turned into cylinders, only to have the actual plastic cylinders become squares. As if the amazing visual trick wasn’t impressive enough, Sugihara then outdid himself by adding several different types of groupings even more complicated and unbelievable than the original. It left almost everyone who saw it scratching their heads, and the internet was pretty desperate for answers.

Samsung thinks you can overcome your fear of spiders using virtual reality

Posted by in category: virtual reality

VR for phobias; makes sense. Scared of spiders? Samsung believes VR may be the treatment for you.


Could you face your fears if you knew you weren’t actually facing your fears? That’s the premise behind a virtual reality experiment Samsung is running for a new app called Itsy, which is designed to help people face their fear of spiders. Created with the help of researchers at Stockholm University, Itsy tries to wean people into giving up their fear of arachnids.

The program is being run by Samsung’s Nordic branch, and the reason is extremely specific.

Using brain signals instead of passwords to unlock computers

Good; and as I had hope it could be done for many years.


Recalling a favorite song could be enough to unlock computers one day. All you’ll need is a tiny earbud to register the electro-brainwaves, researchers say.

Missouri S&T physicist works to predict atom movement

Posted by in categories: particle physics, quantum physics

By laser-cooling atom clusters and studying their movements, a Missouri University of Science and Technology researcher hopes to better understand how atoms and their components are impacted and directed by environmental factors.

With a $400,000 grant from the National Science Foundation, Dr. Daniel Fischer, assistant professor of physics at Missouri S&T, tests the limits of quantum mechanics through his project titled “Control and Analysis of Atomic Few-Body Dynamics.”

In a hand-built vacuum chamber, Fischer manipulates lithium atoms by trapping them in a magnetic field and then shooting them with different lasers. This gives Fischer a large variety of initial states to test. Tests range from single, polarized atoms to larger groups that are laser-cooled to a consistent energy level. By doing so, Fischer works to help unravel the “few-body problem” that continues to confound the world of physics.

No Big Bang –“Our Universe Was Formed From an Older Collapsing Universe”

Posted by in categories: cosmology, materials

A new study of the early universe reveals how it could have been formed from an older collapsing universe, rather than being brand new. The universe is currently expanding and it is a common theory that this is the result of the ‘Big Bang’ – the universe bursting into existence from a point of infinitely dense and hot material.
