Scientists build nanotubes with diameter 60,000 times smaller than a human hair
Some microbiologists at the University of
Massachusetts Amhest have found a way to build electric wires that are
thousands of times thinner than a human hair and even environmentally friendly.
(They have a 1.5 nm diameter 60,000 times smaller than the human hair).
The secret?
"Microbiological nanotubes" or
filaments protein produced by genetic modifications in certain bacteria.
Scientists manipulate bacteria composing wires in heavy so very Nano small from
natural amino acids.
Dr. Derek R.Lovley, chairman of the team,
said that the wires can be produced easily and move because their material is
quite cheap.
It is believed that these wires widely
used in the medical field because they are biological and will not affect the
pH sensitive sensors used to measure the pulse of the heart or kidney function.
Surely one another very important use of
them will be in the field of telecommunications and informatics, where very
small size of the wires will allow for increasing memory capacity for mobile
phones and computers.
Artificial intelligence, a potentially dangerous phenomena
The largest companies in the technology world are joining efforts
for the future of artificial intelligence.
Amazon, DeepMind of Google, Facebook, IBM and Microsoft will
work together on issues such as privacy, security and cooperation between
people. I called Partnership for Artificial Intelligence, it will also involve
external experts.
"We have seen a very rapid development of IA within a
fairly short period," said Prof Yoshua Bengio, from the University of
Montreal. "This field brings exciting opportunities for companies and
public organizations. Yet it raises legitimate questions about how these
developments are progressing. "
Bringing all the best players together will be "the
best way" to ensure that we will all share the same values and overall
objectives to serve the common good, "he added.
Apparent absence in the lineup makes Apple. It has been
discussed by the group to join 'soon', per one of the members.
"IA has great potential to improve many aspects of
life, ranging from health, education, transportation, automation of many
processes ... We hope to maximize this potential to benefit more people,"
said one of the researchers of Allen Institute of Artificial Intelligence.
While the technology is developing too, are raising concerns
on how it will be used.
The chief executive of Tesla, Elon Musk, said the development
of artificial technology "is potentially more dangerous than nuclear
weapons."
A Canadian reveals textile material that eliminates itself the bacteria
Built by two Canadian engineers, named towel "Silver-Bamboo"
it is not only the softest towel ever knitted, but can eliminate 98% of
bacteria themselves collected in, staying always clean and ready to used.
Piyush Maheshwari, one of the project leaders, says he built
this due to a problem he had with the skin. One of the many dermatologists had
said he belonged to the towels we used usually had to wash more than twice a
week as the number of bacteria in double within 20 minutes.
This means that within a few hours in the towel can be found
over 2 million bacteria. When Maheshwari heard, he decided to give a solution
immediately.
He discovered the antibacterial properties of silver and
bamboo and decided to use them on the towel that he wanted to do himself.
"Silver is widely used in health care and medicine that is used in the
early years when it was discovered," he says. "Today, most special
equipment in hospitals use silver as a tool against germs. Bamboo fibers also
contain a natural antibacterial agent called "kun". Bamboo fibers are
soft and absorb moisture better than cotton.
