Researchers believe it is possible to create a quantum invisibility cloak. Anything hidden in it would be shielded from reality on a quantum level.

Researchers are designing tiny particles to act as medicine.
The particles are coated with waterlike molecules that allow them to travel inside the body without being detected by the immune system, Farokhzad said. Their surfaces contain molecules that provide them with a "GPS" to seek out abnormal cancer cells.
Once they find a cancer cell, the particles stick, and like a Trojan horse, the cancer cells take them inside where they can release medicine that's toxic to the cell, Farokhzad said. [Watch the World Science Festival Live.]
In a study published last year in Science Translational Medicine, Farokhzad and colleagues showed that, in people, the nanoparticles delivered a much higher dose of medicine to cancer cells than to other cells in the body. Follow-up studies will test the effectiveness of the drug at treating tumors.

Though universities are rushing to embrace online courses, true education requires one mind engaging with another.
Educators are coaches, personal trainers in intellectual fitness. The value we add to the media extravaganza is like the value the trainer adds to the gym or the coach adds to the equipment. We provide individualized instruction in how to evaluate and make use of information and ideas, teaching people how to think for themselves.
Just as coaching requires individual attention, education, at its core, requires one mind engaging with another, in real time: listening, understanding, correcting, modeling, suggesting, prodding, denying, affirming, and critiquing thoughts and their expression.

Supercomputing for everyone
Great news, the Parallella is now a real computer!! The gigabit ethernet port is working and the full Ubuntu desktop version is up and running! We had some scary moments this week, but in the end everything worked out. Sometimes it’s really worth considering the old advice “if it ain’t broke, don’t fix it”. Amazing how the most innocent of design changes can cause such major headaches at times…

Search is on for signs of microbial activity isolated in Earth's crust. 15 May 2013 Water filtering out of the floor of a deep Ontario mine has been trapped underground for more than a billion years. It bubbles with gasses carrying nutrients that could sustain microbial life.
Scientists working 2.4 kilometres below Earth's surface in a Canadian mine have tapped a source of water that has remained isolated for at least a billion years. The researchers say they do not yet know whether anything has been living in it all this time, but the water contains high levels of methane and hydrogen — the right stuff to support life.
Micrometre-scale pockets in minerals billions of years old can hold water that was trapped during the minerals’ formation. But no source of free-flowing water passing through interconnected cracks or pores in Earth’s crust has previously been shown to have stayed isolated for more than tens of millions of years.
“We were expecting these fluids to be possibly tens, perhaps even hundreds of millions of years of age,” says Chris Ballentine, a geochemist at the University of Manchester, UK. He and his team carefully captured water flowing through fractures in the 2.7-billion-year-old sulphide deposits in a copper and zinc mine near Timmins, Ontario, ensuring that the water did not come into contact with mine air.

A robot as small as a housefly has managed the delicate task of flying and hovering the way the actual insects do.
“This is a major engineering breakthrough, 15 years in the making,” says electrical engineer Ronald Fearing, who works on robotic flies at the University of California, Berkeley. The device uses layers of ultrathin materials that can make its wings flap 120 times a second, which is on a par with a housefly's flapping rate.
This “required tremendous innovation in design and fabrication techniques”, he adds.

Researchers at Stanford University School of Medicine have developed a new technique to see how different types of cells interact in a living mouse.
The process uses light-emitting proteins that glow when two types of cells come close together.
Using the technique, the team was able to pinpoint where in the body metastatic cancer cells ended up after they broke off from an initial tumor site, using readily available lab reagents. The team chose chemicals that are easily available in most life sciences laboratories because they wanted to develop a technique that could be widely used.
