There's a drone for that

A billion people in the world lack access to all-season roads. Could the structure of the internet provide a model for how to reach them? Andreas Raptopoulos of Matternet thinks so. He introduces a new type of transportation system that uses electric autonomous flying machines to deliver medicine, food, goods and supplies wherever they are needed.

A Cherokee Legend

An old Cherokee is teaching his grandson about life. "A fight is going on inside me," he said to the boy.

"It is a terrible fight and it is between two wolves. One is evil - he is anger, envy, sorrow, regret, greed, arrogance, self-pity, guilt, resentment, inferiority, lies, false pride, superiority, and ego." He continued, "The other is good - he is joy, peace, love, hope, serenity, humility, kindness, benevolence, empathy, generosity, truth, compassion, and faith. The same fight is going on inside you - and inside every other person, too."

The grandson thought about it for a minute and then asked his grandfather, "Which wolf will win?"

The old Cherokee simply replied, "The one you feed."

NASA, Homeland Security Test Disaster Recovery Tool

PASADENA, Calif. -- NASA and the U.S. Department of Homeland Security are collaborating on a first-of-its-kind portable radar device to detect the heartbeats and breathing patterns of victims trapped in large piles of rubble resulting from a disaster. 

The prototype technology, called Finding Individuals for Disaster and Emergency Response (FINDER) can locate individuals buried as deep as 30 feet (about 9 meters) in crushed materials, hidden behind 20 feet (about 6 meters) of solid concrete, and from a distance of 100 feet (about 30 meters) in open spaces.

Developed in conjunction with Homeland Security's Science and Technology Directorate, FINDER is based on remote-sensing radar technology developed by NASA's Jet Propulsion Laboratory in Pasadena, Calif., to monitor the location of spacecraft JPL manages for NASA's Science Mission Directorate in Washington.

"FINDER is bringing NASA technology that explores other planets to the effort to save lives on ours," said Mason Peck, chief technologist for NASA and principal advisor on technology policy and programs. "This is a prime example of intergovernmental collaboration and expertise that has a direct benefit to the American taxpayer."

The technology was demonstrated to the media today at the DHS's Virginia Task Force 1 Training Facility in Lorton, Va. Media participated in demonstrations that featured the device locating volunteers hiding under heaps of debris. FINDER also will be tested further by the Federal Emergency Management Agency this year and next.

"The ultimate goal of FINDER is to help emergency responders efficiently rescue victims of disasters," said John Price, program manager for the First Responders Group in Homeland Security's Science and Technology Directorate in Washington. "The technology has the potential to quickly identify the presence of living victims, allowing rescue workers to more precisely deploy their limited resources."

The technology works by beaming microwave radar signals into the piles of debris and analyzing the patterns of signals that bounce back. NASA's Deep Space Network regularly uses similar radar technology to locate spacecraft. A light wave is sent to a spacecraft, and the time it takes for the signal to get back reveals how far away the spacecraft is. This technique is used for science research, too. For example, the Deep Space Network monitors the location of the Cassini mission's orbit around Saturn to learn about the ringed planet's internal structure.

"Detecting small motions from the victim's heartbeat and breathing from a distance uses the same kind of signal processing as detecting the small changes in motion of spacecraft like Cassini as it orbits Saturn," said James Lux, task manager for FINDER at JPL.

In disaster scenarios, the use of radar signals can be particularly complex. Earthquakes and tornadoes produce twisted and shattered wreckage, such that any radar signals bouncing back from these piles are tangled and hard to decipher. JPL's expertise in data processing helped with this challenge. Advanced algorithms isolate the tiny signals from a person's moving chest by filtering out other signals, such as those from moving trees and animals.

Similar technology has potential applications in NASA's future human missions to space habitats. The astronauts' vital signs could be monitored without the need for wires.

The Deep Space Network, managed by JPL, is an international network of antennas that supports interplanetary spacecraft missions and radio and radar astronomy observations for the exploration of the solar system and the universe. The network also supports selected Earth-orbiting missions.

No one knows the answers to these questions.

Published on Mar 17, 2012

Chris Anderson shares his boyhood obsession with quirky questions that seem to have no answers.

This #July4th I stand by the 4th Amendment and against the #NSA's unconstitutional surveillance of Internet users.

http://www.thndr.it/12868Us

Amendment IV
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.^[1]

The recent revelations about the NSA's illegal dragnet spying programs have exposed a government that systematically violates our most basic rights. This Fourth of July, the people are pushing back.

The U.S. government wants to ignore the Fourth Amendment. Let's make that completely impossible by sharing it EVERYWHERE this 4th of July. Declare your independence from NSA spying. Join the protest! Join this Thunderclap, and on July 4th the Internet will light up the 4th Amendment as if it were fireworks.

Organizations like EFF, and awesome websites like Wordpress, Reddit, Namecheap, Imgur, 4chan, Fark, and Cheezburger will all be participating, just like during the SOPA strike. But we need your voice too. Will you join us? Grassroots Internet users have organized Restore the Fourth street protests all over the U.S. this July 4th to demand an end to warrantless government surveillance. In solidarity with that effort, and building off the energy of the 500,000+ StopWatching.us coalition, the Internet Defense League will raise the "Cat Signal" to amplify the message of those protesting in the streets and make sure that the U.S. Government knows: spying on all of us without probable cause is not an option. It's illegal. It's unconstitutional. It's against everything the USA is supposed to be about.

Got a website? You can join the action by putting this message with the 4th Amendment on your site. Get the code, and find out lots more ways to protest on July 4th, at CallForFreedom.org 

Sixty-five years ago today...

Sixty-five years ago today, the Manchester Small Scale Experimental Machine—nicknamed “Baby”—became the earliest computer in the world to run a program electronically stored in its memory. This was a flagship moment: the first implementation of the stored program concept that underpins modern computing.

Q. What did the grape say when the elephant sat on it?

A. Nothing. It just gave a little wine.

Jackson Katz: Violence against women — it's a men's issue

Published by TED on May 29, 2013
Domestic violence and sexual abuse are often called "women's issues." But in this bold, blunt talk, Jackson Katz points out that these are intrinsically men's issues -- and shows how these violent behaviors are tied to definitions of manhood. A clarion call for us all -- women and men -- to call out unacceptable behavior and be leaders of change.

What if You Were Born in Space?

Awesome as usual.

Andres Lozano: Parkinson's, depression and the switch that might turn them off

Published on Apr 18, 2013

Deep brain stimulation is becoming very precise. This technique allows surgeons to place electrodes in almost any area of the brain, and turn them up or down -- like a radio dial or thermostat -- to correct dysfunction. A dramatic look at emerging techniques, in which a woman with Parkinson's instantly stops shaking and brain areas eroded by Alzheimer's are brought back to life. (Filmed at TEDxCaltech.)

Dan Pallotta: The way we think about charity is dead wrong

Activist and fundraiser Dan Pallotta calls out the double standard that drives our broken relationship to charities. Too many nonprofits, he says, are rewarded for how little they spend -- not for what they get done. Instead of equating frugality with morality, he asks us to start rewarding charities for their big goals and big accomplishments (even if that comes with big expenses). In this bold talk, he says: Let's change the way we think about changing the world.
