Sri Lanka may soon become the first country in the world to have universal Internet access. On July 28, the government of Sri Lanka signed a Memorandum of Understanding with Google to launch Project Loon, according to Sri Lanka Internet newspaper ColumboPage.

Google is already working on a massive and global computing grid. Eventually, says Mr Saffo, “they’re trying to build the machine that will pass the Turing test,” in other words, an artificial intelligence that can pass as a human in written conversations. Wisely or not, Google wants to be a new sort of deus ex machina.

Scientists at the National Institute of Standards and Technology (NIST) have created polymer nanotubes that are unusually long (about 1 centimeter) as well as stable enough to maintain their shape indefinitely.
The nanotubes may have biotechnology applications as channels for tiny volumes of chemicals in nanofluidic reactor devices, for example, or as the “world’s smallest hypodermic needles” for injecting molecules one at a time.

Researchers at the University of California, San Diego School of Medicine, the Gladstone Institutes in San Francisco and colleagues have reported the creation of long-term, self-renewing, primitive neural precursor cells from human embryonic stem cells (hESCs) that can be directed to become many types of neurons without increased risk of tumor formation.
To produce the neural stem cells, the researchers added small molecules… read more
Graphene and associated one-atom-thick crystals offer the possibility of a vast range of new materials and devices by stacking individual atomic layers on top of each other, new research from The University of Manchester shows.

Researchers who launched an experimental cyber attack on an electrical power plant caused a generator to self-destruct, alarming the federal government and electrical industry about what might happen if such an attack were carried out on a larger scale.
Economist Scott Borg projects that if a third of the country lost power for three months, the economic price tag would be $700 billion.
Computer experts have long warned… read more

Duke University Medical Center treated brain tumors known as glioblastomas by taking white blood cells from 21 patients, exposing them to parts of the cytomegalovirus (often found in these cancers), and injecting the cells back into the patients. Their preliminary results suggest that this technique is safe and effective.
“Because the immune system kills both the virus and the cell it resides in, we are hoping that… read more

Modern encryption techniques are tested every time someone makes a purchase over the Internet or spends electronic cash stored in smart cards. These strategies rely on so-called one-way functions, which are easy to execute in one direction (for instance, multiplying two prime numbers) but difficult to reverse (factoring a large number into two primes). With ever-increasing computer power and advances in quantum computing, however, such methods may soon become breakable.… read more

The new method works with porous nanomaterials that are riddled with tiny voids, which give them unique optical, electrical, chemical, and mechanical properties. There are nanoporous forms of gold, silicon, alumina, and titanium oxide, among others.
The technique involves the… read more

Cornell researchers have created an innovative way to make and pattern nanoscale wires and other devices without requiring expensive lithographic tools; uses include computer memory and circuits, and quantum dots.
They coated gold nanoparticles suspended in water with a synthetic-DNA-based ligand that adheres to the metal and to water. Adjusting the DNA lengths can precisely control the distance between the particles to make them assemble into orderly superlattices, rather… read more

Ohio State University researchers have come up with a modified molecular combing technique for creating arrays of stretched DNA molecules that could have applications in nanoelectronics, biological or chemical sensors, and genetic analysis and medical diagnosis.
By patterning a large quantity of stretched DNA molecules into a well-defined array of nanowires, parallel and automated analysis may be realized to achieve higher throughput and reliability, they believe.

Neuroscientists have presented evidence that they can create a “body swapping” illusion by using VR helmets, showing that the brain, when tricked by optical and sensory illusions, can quickly adopt any other human form, no matter how different, as its own.
Based on virtual-reality experiments, the technique could have a profound effect on a range of therapeutic techniques. In these studies, researchers create avatars that mimic a person’s every… read more

Stanford bioengineers have hacked the DNA of yeast, reprograming these simple cells to make opioid-based medicines* via a sophisticated extension of the basic brewing process that makes beer.
Led by Associate Professor of Bioengineering Christina Smolke, the Stanford team has already spent a decade genetically engineering yeast cells to reproduce the biochemistry of poppies, with the ultimate goal of producing opium-based medicines, from start to… read more
Stanford researchers are out to prove that object construction in virtual worlds can be sophisticated without being difficult.
