Tiny chip mimics brain, delivers supercomputer speed

Researchers Thursday unveiled a powerful new postage-stamp size chip delivering supercomputer performance using a process that mimics the human brain.

The so-called “neurosynaptic” chip is a breakthrough that opens a wide new range of computing possibilities from self-driving cars to artificial intelligence systems that can installed on a smartphone, the scientists say.

The researchers from IBM, Cornell Tech and collaborators from around the world said they took an entirely new approach in design compared with previous computer architecture, moving toward a system called “cognitive computing.”

"We have taken inspiration from the cerebral cortex to design this chip," said IBM chief scientist for brain-inspired computing, Dharmendra Modha, referring to the command center of the brain.

A Mexican Scientist Just Invented a ‘Telekinesis’ Helmet
A researcher just made a remarkable breakthrough in the area of brain-computer interfaces—creating a rig that allows a user to operate machines with thought alone, almost literally granting a form of ‘telekinesis’ over attached devices.
Brain-computer interfaces are a rapidly expanding area of research and industry. Though the technology to read brainwaves from the head’s surface has been around for decades, scientists and engineers have only recently created numerous systems to read signals directly from the brain and translate them into commands that control computers.
In the future, these technologies could allow people with physical disabilities to control their environment through thought alone—the brain-computer interface effectively grants users a form of telekinesis. With an increasingly digital world, brain-computer interfaces (BCIs) could allow future generations to interact with technology telepathically. Many of the early BCI studies were promising, but the technology was difficult to use and mentally exhausting.

How Nanotechnology Could Reengineer Us
from Keithly:

Nanotechnology is an important new area of research that promises significant advances in electronics, materials, biotechnology, alternative energy sources, and dozens of other applications. The graphic below illustrates, at a personal level, the potential impact on each of us. And where electrical measurement is required, Keithley instrumentation is being used in an expanding list of nanotechnology research and development settings.

I don’t mean to “steal” this post from Mathispun, but here’s a quick caption for this cool gif. (Caption made available to you by Wikipedia and my copy and pasting skills).
A pair of parabolas face each other symmetrically: one on top and one on the bottom. Then the top parabola is rolled without slipping along the bottom one, and its successive positions are shown in the animation. Then the path traced by the vertex of the top parabola as it rolls is a roulette shown in red, which happens to be a cissoid of Diocles. In geometry, the cissoid of Diocles is a cubic plane curve notable for the property that it can be used to construct two mean proportionals to a given ratio. In particular, it can be used to double a cube. Doubling the cube (also known as the Delian problem) is one of the three most famous geometric problems unsolvable by compass and straightedge construction. It was known to the Egyptians, Greeks, and Indians. To “double the cube” means to be given a cube of some side length s and volume V = s^3, and to construct the side of a new cube, larger than the first, with volume 2V and therefore side length s * cube root 2. The problem is known to be impossible to solve with only compass and straightedge, because cube root 2 (≈ 1.25992105…) is not a constructible number.

How do Trees Survive Winter?

Humans can go inside or put on clothes, but trees spend winter naked in the cold. Why don’t they all die?

Particles coming from the universe (cosmic rays) are crossing the earth all the time – they are harmless but invisible to us, also called natural radiation. Cloud chambers are detectors to make the tracks of the particles visible. In its most basic form, a cloud chamber is a sealed environment containing a supersaturated vapor of water or alcohol. When a charged particle (for example, an alpha or beta particle) interacts with the mixture, it ionizes it. The resulting ions act as condensation nuclei, around which a mist will form (because the mixture is on the point of condensation). The high energies of alpha and beta particles mean that a trail is left, due to many ions being produced along the path of the charged particle. These tracks have distinctive shapes (for example, an alpha particle’s track is broad and shows more evidence of deflection by collisions, while an electron’s is thinner and straight). When any uniform magnetic field is applied across the cloud chamber, positively and negatively charged particles will curve in opposite directions, according to the Lorentz force law with two particles of opposite charge.Build one: http://www.amnh.org/education/resources/rfl/web/einsteinguide/activities/cloud.htmlor here: http://teachers.web.cern.ch/teachers/document/cloud-final.pdfAn even cheaper/quicker/easier version here:http://blogs.scientificamerican.com/critical-opalescence/2012/10/15/how-to-build-the-worlds-simplest-particle-detector/Professor Brian Cox explains:https://www.youtube.com/watch?v=fWxfliNAI3UVia Wiki
