From Geeks are Sexy Technology News: WiFi Blocking Wallpaper

Home Network security seems to be a simple thing these days. It is not difficult to set your router with the proper security measures to stop others from hopping on your WiFi signal and getting that internet service you are likely over paying for.

Of course this magical block that keeps out WiFi pirates really comes down to a password. It’s a tiny bit more complicated than that, but for the most part this is all it takes to make your home network private instead of branding it a hotspot and sharing it like the town bicycle.

But of course there are ways around these security measures, and if you want to keep signal thieves out of your network, here a product that will likely stop them dead in their tracks.

WiFi Blocking Wallpaper.

With all the logic of a giant wall of stones, the Institut Polytechnique de Grenoble developed a coating of silver ink that can be embedded into a wallpaper to block out the electromagnetic frequencies of wireless networks, but still allow the signals of cell phones to pass through. No word on how windows would affect this technology (We found a hole in their security – literally!)

The ING researchers have granted Finnish company Ahlstrom exclusive rights to manufacture the wallpaper, and it is expected to go on sale in 2013. They explain that it should cost the same as a mid-range traditional wallpaper.

To me this seems a little extreme, but there are some conspiracy theorists out there who I’m sure want a more fashionable alternative than a tinfoil hat to keep those invasive wireless signals out. And if fashion is a big concern and you do not care for the patterns offered, painting over or layering different wallpapers does not affect its ability to block WiFi.

I am sure there will be some application somewhere to some organization where security is never enough and they need walls that WiFi cannot pass through. I just can’t see this being a regular household precaution.

Maybe if I sell my house to people that peeve me off, I can put this stuff up just to know that they are likely going insane trying to figure out why their WiFi works awesome inside, but not in the backyard. That might be fun.

From Autoblog: Subaru Legacy that spent 3 months at bottom of Finnish lake starts on first try

Filed under: , ,

“Ja, that ice’ll hold ya.” Until it didn’t, and suddenly a man’s 1996 Legacy wagon was at the bottom of a shallow lake in Finland. Three months later, the Subaru wagon was dragged from its freshwater slumber, and while most people would just write the car off or at most turn it into a parts donor, curiosity got the better of the rescue squad.

Would it run? Just how bad was the damage? Before plunging below the surface, the owner did have time to shut the engine down and get his dogs out, so the boxer four didn’t aspirate any water and electrons weren’t coursing through the various circuits, two details that likely saved a bunch of damage. After removing a live fish from the engine bay, draining a lot of water from the fuel tank and crankcase, and a fresh fill of fluids and spark plugs, lo and behold, the SCUBA-ru chugged to life on the first try.

It’s not perfect; until the residual water works its way through the fuel system it’s going to feel a little low on power, and oxidation may start to fiercely assert itself. The smell is probably epic, too, but this is one funkbox with a great story.

From Discover Magazine: Some Imported Shrimp on Grocery Store Shelves are Contaminated with Antibiotics | 80beats

Most of us assume that by the time food arrives at the grocery store, it’s been checked for any chemicals that might harm us. That’s not necessarily the case: food manufacturers and federal employees test for some known culprits in some foods, but the search isn’t exhaustive, especially when it comes to imported items. Recently, scientists working with ABC News checked to see whether imported farmed shrimp bought from grocery stores had any potentially dangerous antibiotic residue, left over from the antibiotic-filled ponds in which they are raised. It turns out, a few of them did.

Out of 30 samples taken from grocery stores around the US, 3 turned up positive on tests for antibiotics that are banned from food for health reasons. Two of the samples, one imported from Thailand and one from India, had levels of carcinogenic antibiotic nitrofuranzone that were nearly 30 times higher than the amount allowed by the FDA. The other antibiotics the team discovered were enroflaxin, part of a class of compounds that can cause severe reactions in people and promote the growth of drug-resistant bacteria, and chloramphenicol, an antibiotic that is also a suspected carcinogen.

These findings aren’t entirely surprising. …
