Graphene – World’s Strongest Known Material

Strongest Known Material

 

Graphene, praised for its electrical properties, has been proven the strongest known material.

Materials scientists have been singing graphene’s praises since it was first isolated in 2005. The one-atom-thick sheets of carbon conduct electrons better than silicon and have been made into fast, low-power transistors. Now, for the first time, researchers have measured the intrinsic strength of graphene, and they’ve confirmed it to be the strongest material ever tested. The finding provides good evidence that graphene transistors could take the heat in future ultrafast microprocessors.

Magnetic Nanotechnology Used To Capture Cancer

Catching cancer before it metastasizes, or spreads throughout the body, is one way to increase your chances of survival. Now scientists may have found a way to help even when cancer is already on the move, by using magnets to lasso cancer cells and drag them out of the body.

Growing Neural Implants

 Growing Neural Implants

Anything worth having, is worth implanting

New approaches could more seamlessly integrate medical devices into the body.

Conductive polymer coatings that weave their way into implanted tissue might one day improve the performance of medical implants, such as cochlear implants and brain stimulators used to treat Parkinson’s disease. In early studies, neural interfaces coated with an electrically conductive polymer outperformed conventional metal counterparts. Scientists at the University of Michigan hope that the material’s novel properties will help lessen the tissue damage caused by medical implants and boost long-term function.

Acoustic Cloak Material Designed

Acoustic Cloak Material Designed 

 

 Sound waves moving from left to right flow past the object and reform on the other side with no distortion.

City dwellers, rest easy. Engineers have designed a material that redirects sounds and could be used in buildings to shield them from noises. The sound-shielding material, which, if actually made, would be the first acoustic cloaking device, could also be useful in hiding military ships and other vessels from sonar.

 Bugging the Forest

 

Have you ever wondered what happens in the rainforest when no one is looking?

Research in the University of Alberta’s Faculty of Science may soon be able to answer that question. The departments of computing science and earth and atmospheric science have been working together to create a Wireless Sensor Network that allows for the clandestine data collection of environmental factors in remote locations and its monitoring from anywhere in the world where the Internet is available.

Can Robots Evolve? On Building the “Conscious” Machine…

conscious-machine_cp3hb_2263.jpg  

How would you build a conscious machine? Well to begin with I’d get Life Insurance and then take my brain and put it in a jar and freeze my body. Then hundreds of years later wake me up and transplant me into an IronMan. Yes, I partially got that idea from the movie IronMan and from Futurama. I’m still going to do it though. But more to the point, Christof Koch and Giulio Tononi both have good points of in their articles that they wrote on consciousness and robots.

Nanomaterials Movement Measured in Simple Model Food Chain

New research* shows that while engineered nanomaterials can be transferred up the lowest levels of the food chain from single celled organisms to higher multicelled ones, the amount transferred was relatively low and there was no evidence of the nanomaterials concentrating in the higher level organisms.

The Miracle of Bionics – Presenting Challenging Questions

 Oscar Pitorius – the “blade runner”

Oscar Pistorius – also known as ‘Blade Runner’ – is a double leg amputee who is using specially developed artificial legs to compete in races. A world record holder in the 100, 200 and 400 meters Paralympic events, Pistorius was denied by the International Association of Athletics Federations (IAAF) his application to participate in the 2008 Summer Olympics. The IAAF argued that his prosthetic racing legs give him a clear competitive advantage. On May 16, the IAAF’s decision was overturned by the Court of Arbitration for Sport, allowing Pistorius to participate in the Olympics if he could make the minimum qualifying time.
This episode drives home the monumental issues our society will be facing in the not too distant future thanks to our increasing technological ability to enhance the human body.

Childhood Exposure to Lead Linked to Adult Crime

 Childhood Exposure to Lead Linked to Adult Crime

Possibles sources of lead poisoning

In what may be the strongest link yet between lead exposure and crime rates, researchers at the University of Cincinnati on Tuesday released new evidence, spanning more than 20 years, that draws a direct relationship between the amount of lead in a child’s blood and the likelihood he or she will commit crimes as an adult.
