The Shadow Internet That’s 100 Times Faster Than Google Fiber

When Google chief financial officer Patrick Pichette said the tech giant might bring 10 gigabits per second internet connections to American homes, it seemed like science fiction. That’s about 1,000 times faster than today’s home connections. But for NASA, it’s downright slow.

While the rest of us send data across the public internet, the space agency uses a shadow network called ESnet, short for Energy Science Network, a set of private pipes that has demonstrated cross-country data transfers of 91 gigabits per second–the fastest of its type ever reported.

IBM Develops a New Chip That Functions Like a Brain

Inspired by the architecture of the brain, scientists have developed a new kind of computer chip that uses no more power than a hearing aid and may eventually excel at calculations that stump today’s supercomputers.

The chip, or processor, is named TrueNorth and was developed by researchers at IBM and detailed in an article published on Thursday in the journal Science. It tries to mimic the way brains recognize patterns, relying on densely interconnected webs of transistors similar to the brain’s neural networks.

Dying Twice

Posted by in categories: biotech/medical, existential risks

Dying Twice

Of course, Ebola can be stopped: By rigorously restricting locomotion for the population. But this presupposes heavy support networks. At the present moment in time, this strategy is still feasible. However, since the disease is spreading exponentially in both number and area, very soon the resources of aid-giving nations will be overtaxed. Then the Big Dying from Ebola will be accompanied by the Big Dying from hunger and thirst due to restricted locomotion without the necessary support services.

There exist institutions that could help. But they all do not know what “dying twice” means:
FIRST: from having become untouchable and unapproachable;
SECOND: from thirst, hunger and the pangs of the disease which are intolerably ugly and stenching.
Mothers do not mind. But where are all the mothers for the dying? Even Jesus’ mother was there at the cross.

Since the disease is doubling every 3 weeks (only at some places the rate is slowed due to restricted locomotion), someone must make a “war plan.” I am sure some wonderful organizations have already done so, but they must join forces, resources and above all: information.
One joint plan must be negotiated, maybe under the auspices of the Vatican?, or the CDC?, or Castroland? It need not be the money-stripped United Nations. Only: SOON!

How to enable the Internet of Things without batteries

Posted by in categories: engineering, internet

Kurzweil AI

University of Washington engineers have designed a clever new communication system called Wi-Fi backscatter that uses ambient radio frequency signals as a power source for battery-free devices (such as temperature sensors or wearable technology) and also reuses the existing Wi-Fi infrastructure to provide Internet connectivity for these devices.

“If Internet of Things devices are going to take off, we must provide connectivity to the potentially billions of battery-free devices that will be embedded in everyday objects,” said Shyam Gollakota, a UW assistant professor of computer science and engineering.

‘Nano-pixels’ promise thin, flexible, high resolution displays

A collection of still images drawn with the technology

A team led by Oxford University scientists explored the link between the electrical and optical properties of phase change materials (materials that can change from an amorphous to a crystalline state). They found that by sandwiching a seven nanometre thick layer of a phase change material (GST) between two layers of a transparent electrode they could use a tiny current to ‘draw’ images within the sandwich ‘stack’.

Initially still images were created using an atomic force microscope but the team went on to demonstrate that such tiny ‘stacks’ can be turned into prototype pixel-like devices. These ‘nano-pixels’ – just 300 by 300 nanometres in size – can be electrically switched ‘on and off’ at will, creating the coloured dots that would form the building blocks of an extremely high-resolution display technology.

The World’s First Photonic Router

Posted by in category: physics

Weizmann Institute

Dr. Barak Dayan's group at the Weizmann Institute

Weizmann Institute scientists have demonstrated for the first time a photonic router – a quantum device based on a single atom that enables routing of single photons by single photons. This achievement, as reported in Science magazine, is another step toward overcoming the difficulties in building quantum computers.

At the core of the device is an atom that can switch between two states. The state is set just by sending a single particle of light – or photon – from the right or the left via an optical fiber. The atom, in response, then reflects or transmits the next incoming photon, accordingly. For example, in one state, a photon coming from the right continues on its path to the left, whereas a photon coming from the left is reflected backwards, causing the atomic state to flip. In this reversed state, the atom lets photons coming from the left continue in the same direction, while any photon coming from the right is reflected backwards, flipping the atomic state back again. This atom-based switch is solely operated by single photons – no additional external fields are required.

Your iPhone Can Finally Make Free, Encrypted Calls

signal

If you’re making a phone call with your iPhone, you used to have two options: Accept the notion that any wiretapper, hacker or spook can listen in on your conversations, or pay for pricey voice encryption software.

As of today there’s a third option: The open source software group known as Open Whisper Systems has announced the release of Signal, the first iOS app designed to enable easy, strongly encrypted voice calls for free. “We’re trying to make private communications as available and accessible as any normal phone call,” says Moxie Marlinspike, the hacker security researcher who founded the nonprofit software group. Later this summer, he adds, encrypted text messaging will be integrated into Signal, too, to create what he describes as a “single, unified app for free, easy, open source, private voice and text messaging.”

Method of Sustainable Fuel-less Terra-forming of Venus & Mars

Terra Forming Venus & Mars by leveraging Asteroids
Inspired by: Lifeboat Foundation

Both Mars and Venus can be terra-formed to provide Earth-like gravity and atmospheres; Venus with an effort of about 100 years to terra-form the atmosphere, and Mars with an effort of about 2,000 years to terra-form the atmosphere. These are both potentially realized through the use of systems of solar sails. Asteroids provide many of the resources needed to seed related development.

Organs-on-Chips emulate human organs, could replace animals in tests

Emulate's lung-on-chip, seen here, is lined with human lung and blood vessel cells

The search for more efficient tests of pharmaceuticals without animal models is taking a stride forward, with a new technology being developed in the US called Organs-on-Chips. The new miniature platform and software, which mimic the mechanical and molecular characteristics of human organs, were developed by bioengineers from the Wyss Institute for Biologically Inspired Engineering at Harvard University.

The device, about the size of a small computer memory stick, is created using microchip-manufacturing techniques. It features a porous flexible membrane that separates two channels at the center of the device. The channels are filled with living human cells and tissues cultured in a fluid that mimics the environment inside the human body. Micro-engineering and automated instrumentation allows the system to perform real-time analysis of biochemical, genetic and metabolic functions within single cells.
