New Skin? A Plastic That Heals Itself, Conducts Electricity, and is Sensitive To Touch
Skin is a material with astonishing capabilities: the flexible, waterproof layer constantly regenerates itself, heals itself after scratches and cuts, and, through its nerves, conducts electricity, relaying the sense of touch to the brain. Engineers have long been trying to come up with a synthetic polymer that does all those things, and does them under standard conditions rather than the carefully calibrated set-up of a lab. Now engineers have created a polymer with a combination of skin’s most elusive attributes that no polymer had achieved before: This new material, reported in Nature Nanotechnology, can conduct electricity and, when it is sliced open with a razor, can heal itself at room temperature.
The material can come back together thanks to the hydrogen bonds, which break and reform easily and reversibly, connecting its molecules. Due to the addition of nickel particles, it can also conduct electricity. The researchers found that after the material was cut open, it regained 90 percent of its electrical conductivity within 15 seconds. What’s more, the material’s electrical resistance changes in response to pressure—giving this synthetic skin what is, essentially, a sense of touch. The material may eventually be used to make touch-sensitive prosthetic limbs. Meanwhile, the resilient, conductive material should aid in the development of better on-skin electronic devices, such as wearable heart-rate monitors.
Increased tax subsidies for politically correct media 2015-03-29 22:08
On Dec 9 last year I translated a random snapshot of the biggest newspaper in Sweden. The headlines alone spoke for themselves. It was, simply put, an orgy of political correctness, obvious attempts at emotional manipulation and general national self-loathing. In other words, a typical Swedish newspaper on any given day.
As more and more readers are waking up to the ...
When obeying the law and supporting yourself is racist 2015-03-29 22:56
There is a huge scandal in the municipality of Ă„lmhult in Sweden. It has been revealed that there is a letter that may have been sent from the municipality offices to newly arrived immigrants informing them that the law applies to them and that theyâ€™re expected to eventually go off the dole and start pulling their own weight in society.
New political weapon: Threat to unleash immigrant invasion 2015-03-29 22:05
Youtube description: Threatening to bombard a country with illegal immigrants has become quite the bargaining chip in political quarrels, as Polly Boiko explains.
Editors Note: Notice how the argument is twisted around at the end of the report. The word "Bogeyman" is used. This is a common allusion to a mythical creature. What is mythical about replacement immigration into Europe? ...
Facebook completes first drone flight above UK, Mark Zuckerberg confirms 2015-03-28 3:15
Solar powered drones which provide internet access to rural and remote areas have been trialled in UK for first time by Facebook.
They â€śhave a wingspan greater than a Boeing 737 but will weigh less than a carâ€ť, according to the social network's chief Mark Zuckerberg.
The drones, developed by Somerset-based company Ascenta which Facebook bought last March, will beam down laser-guided ...
