Friends, file this one under “Wow”. IBM researchers just discovered a way to store data on a single atom. Data storage is undergoing dramatic evolution, recently researchers successfully stored digital data — an entire operating system, a movie, an Amazon gift card, a study and a computer virus — in strands of DNA.
The IBM researchers have developed the world’s smallest magnet using a single atom and they packed it with one bit of digital data. Currently, hard drives use about 100,000 atoms to store a single bit of information — a 1 or 0 — using traditional methods. So, this breakthrough could allow people to store 1,000 times more information in the same amount of space in the future applications.
The discovery, which was described in the journal Nature, builds on 35 years of nanotechnology history at IBM, including their Nobel prize-winning scanning tunneling microscope (STM) that was used to build the atomic hard drive. The scientists used a single atom of the rare earth element holmium and carefully placed it on a surface of magnesium oxide, which makes its north and south poles hold in a stable direction. The two stable magnetic orientations define the 1 and 0 of the bit. The researchers then used a very accurate, sharp, and small, needle to pass an electrical current through the holmium atoms that flips its north and south poles, thus replicating the process of writing binary data (1s and 0s) to a traditional magnetic hard drive.

Friends, this looks really interesting…
Adding to the existing portfolio of some 700 programming languages is a new release candidate for Scramblecode, a security-oriented offering from Danish software vendor ProgramPartner ApS. Scramblecode is all about encryption and safety.
Scramblecode is an easy to learn programming language based on curly brackets and classes,” the company says on its Web site. “It uses encrypted compilation to secure the code, and protects the execution while working with encrypted variables.
The company today announced release candidate 1 (RC1) for Scramblecode, which is available for download and testing that can be done completely off-line on a variety of machines. The Scramblecode package comes with its own IDE, including a code editor, test bench and debugger. The company said that because Scramblecode implements memory encryption, ordinary debugging and memory analysis tools aren’t effective. Built for Windows development, Scramblecode lets coders load a virtual machine (VM) into memory to execute private assembler instructions and it individually protects each instruction and works with encrypted variables in memory. Furthermore, an attack that cracks just one instruction (or even one bit) could crash program execution.

If you look in the VooDoo Tech section, you’ll see we endorse both ProtonMail and Tor. Both are excellent services if you value your online privacy and now they work together! ProtonMail, launched in 2014 by a group of MIT and CERN experts, is the largest email encryption service provider in the world having more than two million users. It is the preferred emailing platform of activists and journalists who need to keep information confidential. In its latest announcement, ProtonMail’s co-founder Dr. Andy Yen stated that they would allow the users to directly access their email accounts via Tor network so that they could counter steps taken by authoritative governments across the globe to minimize user privacy.
Dr. Yen said that it is inevitable to avoid censorship in some countries and they have been “proactively working to prevent this.” Dr. Yen further acknowledged that the reason why they have chosen Tor is that “Tor provides a way to circumvent certain Internet blocks so improving our compatibility with Tor is a natural first step.”
This perhaps looks like a step taken after the recent actions from the governments to curb the public’s access to encrypted platforms and secure internet usage. Such as Egyptian government blocked encrypted chat application Signal and the UK government’s approval of the Investigatory Powers Bill aimed at tracking the activities of web browsers. Friends, do yourself a favor… Use Tor and get yourself a ProtonMail account.

Friends, this is some cool tech… Carnegie Mellon’s CyLab Security and Privacy Institute is touting research that provides visualization of the reams of network traffic data (i.e., IP addresses and time stamps) that IT and security analysts typically examine. This makes it easier to spot DDoS patterns. “Visualization is one way to change abstract data into pictures, sound, and videos so you can see patterns in a very intuitive way”, so says Senior Systems Scientist Yang Cai of CyLab’s Visual Intelligence Studio. Check out a demonstration below…
Ever heard of “Composite Metal Foams” (CMFs)? Turns out, this technology has been around for quite a while and has a wide range of applications. These materials are tough enough to turn an armor-piercing bullet into dust on impact but weigh a fraction of plate armor.
Afsaneh Rabiei, a professor of mechanical and aerospace engineering at NC State, has spent years developing CMFs. The video below shows a specimen made out of her composite metal foams. The bullet in the video is a 7.62 x 63 millimeter M2 armor piercing projectile, which was fired according to the standard testing procedures established by the National Institute of Justice (NIJ). As you can see, the results were dramatic.
“We could stop the bullet at a total thickness of less than an inch, while the indentation on the back was less than 8 millimeters,” Rabiei says. “To put that in context, the NIJ standard allows up to 44 millimeters indentation in the back of an armor.”
