How to build your family tree on the Web
Researching your family tree seems as easy as conducting a Google search, but there’s actually much more work and fact-checking involved, if you want to do it right.
Ancestry.com is no longer the only option when it comes to searching digital archives, connecting with others and compiling a family tree. A new crop of geneaology sites popping up on the Internet are providing some alternatives. MyHeritage and Archives.com are two useful sites that have great layouts and access to plenty of documents. On these sites you can find census records, scanned birth, marriage and death certificates, family photos and newspaper clippings, and compile these into a beautiful, digital tree.

Liquid metal used to create ultra stretchable wires.
A new type of conductive wire uses a gallium and indium liquid metal alloy inside an extremely thin elastic polymer tube to create a wire which can be stretched to up to eight times it’s size without losing electrical conductivity.
The wire could be used for headphone cables or phone chargers, and can be mass produced using current methods. The cable might not yet make it to market though - if the cable is cut the liquid metal leaks out, causing a possible hazard.
Check out a video of the cable being stretched here.
New data shows that since Google launched its iOS mapping application, there has been a 30 percent bump in people upgrading their devices to Apple’s newest mobile operating system.
‘Metapaper’ blocks Wi-Fi signals.
French researchers have developed a wallpaper able to block Wi-Fi signals, while still allowing FM radio waves and emergency frequencies to pass through. Known as metapaper, it is able to filter out 99% of all waves coming from the outside.
Possible uses could include creating quiet spaces inside movie theaters or hospitals, or for the ultra paranoid it could be used to stop the neighbors stealing your Wi-Fi or hacking into a wireless home network.
The snowflake patterned wallpaper can be covered with traditional wallpaper. The makers are pushing it as a ‘healthy alternative’, citing studies showing that overexposure to electromagnetic waves could cause adverse health affects.
Nielsen’s new Connected Devices study is out:
- Social Media — 44% of 18-24 year olds and close to 50% of 25-34 year olds are visiting social networking sites on their smartphones during both commercials and programs while watching TV.
- Seeking Information — 36% of people 35-54 and 44% of people 55-64 use their tablets to dive deeper into the TV program they are currently watching.
So the older folks are relying on search to make their experience of TV richer, while the youths are relying on each other.
New DARPA RFP Calls for All-In-One HUD that Sees Through Smoke, In The Dark and In Broad Daylight
DARPA wants a multi-band head-up display, which could be mounted to a helmet or a weapon scope, that combines several wavelengths of light into one image.
Sunny? No problem—the camera can see in visible light. Smoke bomb blocking your view? No sweat; the camera can see thermal infrared signatures. The system would also have near-infrared capability to help users see through darkness.
A new DARPA project called the Pixel Network for Dynamic Visualization (PIXNET) seeks proposals for new sensors that can do all of this in one package. A successful proposal would be small, lightweight, low-power and low-cost, said Nibir Dhar, DARPA program manager for PIXNET.
The system would communicate wirelessly with Android-based smart phones to fuse the images together, like you can see in the inset above. The warfighter would see a scene with visible imagery, thermal sensitivity and near-IR capability all in one.
Existing sensors are a good starting point, but they’re not advanced enough to combine multiple functions the way DARPA wants. Combining reflective and thermal bands will be a challenge, not to mention making it ultra-portable. “What we really need are breakthroughs in aperture design, focal plane arrays, electronics, packaging and materials science,” Dhar said.
