Scientists create cells zombie exceeding acting to live versions

 http://i.imgur.com/29ZOJ1k.jpg

Scientists at the University of New Mexico have created in laboratory cells zombie who perform their duties better than living cells. It's not science fiction. They used a group of breast cells to coat with a suspension of silicon that has completely coated nanometer level. As a result they have obtained cells 'replicants' that outperform their versions 'alive'. Not only that, but are more resistant to extreme environments such as high temperatures and pressures.

Scientists have somehow painted with silicon cells which acts as a permeable armor. After the cell subjected to high temperatures up to 400 degrees, thus the whole cell protein material disappears by evaporation, leaving a remnant a replica formed by a silicon structure.
According to the researchers' zombie cells bind our chemistry and biology to create forms that not only look like their past versions, can also work in the future work. "
So far only isolated cells, but who knows if in the future will be able to create micro (or macro) organisms with the ability to carry out exploration in hostile environments inside and outside our planet.

Floating magnets move chasing a laser, the possible future of maglev vehicles

http://i.imgur.com/v91at.jpg

If you had to name two futuristic inventions that can be found today would probably maglevs lasers and these vehicles almost magically levitating through the effect of magnetism and get impressive speeds.

Aoyama Gakuin University in Japan have united both concepts to give a curious invention: a magnet that levitates on a metal surface and moves chasing a point of light.

The metal surface comprises a matrix of small magnets. The material on the surface coat is composed of graphite and what they do is to illuminate a point just at its edge. This point of light modifies the temperature of graphite piece enough to change the magnetic behavior of the area, the graphite is unbalanced at that point and move in that direction.

It may seem just a game having fun with these scientists in their spare time, but in practice could lead to quite interesting inventions. Maglev vehicles could be designed which would lead to a point of laser light, either manually or through an automated driving system to draw the light path has to trace the vehicle.

Another could be the most revolutionary inventions, there is the possibility of creating generators whose turbines were activated simply using spotlights.

Scientists get to act as old cells young again

It seems that the formula for eternal youth is getting closer, if recently talked about a breakthrough in this regard related to hydras , now at the University of Michigan have discovered another technique that would potentially stop rejuvenate the cells of your body indefinitely.

The discovery in question is not related to the cells of your body directly, but with the surrounding material called extracellular matrix or ECM . Increasing the filling space around the cells that succeeded in older cells act as back to back young cells. It's that simple.

Scientists at the Department of Dermatology at the University of Michigan tested the technique on animals and the good news is that, to be successful, also found that it worked in humans and no known side effects at this time.

Specifically, proved to inject a substance that enhances the MEC in 21 volunteers octogenarians with the result that the skin becomes thickened and began to generate collagen and blood vessels spontaneously. Possibly the invention is not the fountain of youth by itself, but it seems that combining several techniques are appearing recently could start finding enough people with youthful age.

Scientists find a way to implant memories in our mind

http://i.imgur.com/1Srza.jpg

Surely we have seen several science fiction films (as Total Recall) in which an individual is implanted memories in mind. Guess what? Such things are not science fiction: they are part of reality. Scientists are now able to extract personal information directly from our mind, but now they have taken things to another level.
According to a new study, scientists have been able to induce memories inside the mind of a mouse. Professor Ben Stowbridge and one of his students, Robert A. Hyde, were able to create the circuits and the necessary interface to create new memories in the brain of a mouse. Apparently those memories were of short duration, but at least it's a first step that takes this issue out of the conceptual stage to bring the real world.
Apparently during the procedure were activated some isolated areas of the brain, but the changes lasted between 5 and 10 seconds only, which resulted in the recall have a limited duration.
The two scientists expect more research in this field can help fight memory related diseases such as Alzheimer's. Of course the technology will also play their role in this.

Swumanoid, the Japanese robot could replace the lifeguards

 http://i.imgur.com/9wVQN.jpg

Scientists at the Institute of Technology in Tokyo have been very busy lately Swumanoid in developing a humanoid robot capable of swimming and one day could be the replacement of the lifeguards.
Swumanoid The prototype is able to swim and crawl to 0.64 meters per second, you can swim back and even butterfly swimming style that many regard as the most difficult because it is the most stressful, but being a robot, fatigue is not a problem.
The main objective of the team that is developing the Swumanoid is to one day help save the lives of those who are drowning. Are also expected to be used to collect data and repeating patterns to analyze hundreds of times, helping to refine the techniques of human swimmers.


Maybe in 10 years to see these robots saving people on the beaches around the world.

Scientists restore vision in a mouse


http://i.imgur.com/pusn4.jpg


Through the years, there have been reports of various cures for blindness, but this new one seems to be definitive. Researchers and scientists from the University of Berkley have managed to restore the vision of a mouse after injecting a chemical directly in their eyes.

This chemical is known as AAQ, and acts as a kind of photo interrupter, and which does is to unite the ion channel proteins with cells from the surface of the retina. When exposed to light, the chemical changes the flow of ions in the eye, activating neurons and returning the light to the mouse.

If that sounds confusing, it simply means that a small dose of AAQ, the mouse was able to regain his sight temporarily. The effect lasted only a few hours, but of course this fact has led scientists to improve the chemical and are now working on an enhanced version they hope will last a couple of days.

We hope to have more news soon.

Virus attacks nuclear power plant in Iran and requires computers to play AC / DC

 http://i.imgur.com/Sh7vZ.jpg

"E-mails sent by a scientist from the Atomic Energy Organization of Iran reported that a malware has forced computers to play "Thunderstruck" at maximum volume"

Scientists reported earlier this week that computers of a nuclear plant in Iran were attacked by a virus that forced them to play the song "Thunderstruck" the Australian band AC / DC - and at maximum volume.

Mikko Hypponen, chief research officer at security company F-Secure, says he received "a series of e-mails from Iran" this weekend about the attack. The emails have been sent by a scientist at Atomic Energy Organization of Iran (AEOI, which stands for Atomic Energy Organization of Iran, in free translation).

One of the emails was published by the analyst in a blog post on F-Secure , on Monday (23/7).

"I am writing to inform you that our nuclear program was once again attacked and compromised by a new virus that ended our network automation at Natanz and Fordo another facility near Qom [...] The automation network and hardware Siemens were attacked and shut down. [...] There were also some random songs playing in several of the workstations in the middle of the night at full volume. "

However, Hypponen ended the post stating that there "can confirm any details. However, we can confirm that the researcher was sending and receiving e-mails from within the AEOI."

It is not the first time Hypponen has been bombarded with e-mails of this type. Last month, the analyst would have written in Wired about his experience of having received an email from the Computer Emergency Team of Iran, who reported on the discovery of the Flame.

For those who do not remember, the Flame is a spy supervirus developed at the behest of the U.S. government in partnership with Israel, in order to attack and destroy the program of uranium enrichment in Iran
