METI: should we be shouting at the cosmos?

June 19, 2013

Arecibo_message

Science fiction writer and astrophysicist Dr. David Brin is not happy with the Lone Signal announcement of METI (Messaging to Extra-Terrestrial Intelligence) “beams” to the Gliese 526 solar system.

In his Brinstorming Science 2.0 blog, Brin updated his 2006 article on METI (aka active SETI), quoting Carl Sagan, who called it “deeply unwise and immature.”

He also cited Frank Drake, who famously sent the… read more

Diversifying your online world

June 20, 2013

Rewire

In a new book, MIT’s Ethan Zuckerman asserts that we need to overcome the Internet’s sorting tendencies and create tools to make ourselves “digital cosmopolitans.”

The Internet promises a seemingly frictionless way of connecting individuals from around the globe. But in reality, that’s not what happens online: Instead, we clump together with people similar to ourselves, and have those affinities reinforced by tools that guide us… read more

Carbon nanotube electrode senses individual neuron signals

June 20, 2013

nanotube_brain_probe

Neuroscientists have developed a new brain electrode that is a millimeter long, only a few nanometers wide and harnesses the superior electromechanical properties of carbon nanotubes to capture electrical signals from individual neurons.

“To our knowledge, this is the first time scientists have used carbon nanotubes to record signals from individual neurons, what we call intracellular recordings, in brain slices or intact brains of vertebrates,” said Bruceread more

Herbal extract boosts fruit fly lifespan by nearly 25 percent

June 20, 2013

Rhodiola rosea (golden root) is a plant in the Crassulaceae family that grows in cold regions of the world.

The herbal extract of a yellow-flowered mountain plant long used for stress relief was found to increase the lifespan of fruit fly populations by an average of 24 percent, according to UC Irvine researchers.

But it’s how Rhodiola rosea, also known as golden root, did this that grabbed the attention of study leaders. They discovered that Rhodiola works in a manner completely unrelated to dietary restriction and… read more

For less than $100, University of Washington researchers have designed a computer-interfaced drawing pad that helps scientists see inside the brains of children with learning disabilities while they read and write.

A paper describing the tool, developed by the UW’s Center on Human Development and Disability, was published this spring in Sensors, an online open-access journal.

A 1.3-billion-pixel image of the surface of Mars, from NASA’s Mars rover Curiosity, offers armchair explorers a way to examine one part of the Red Planet in great detail. It stitches together nearly 900 exposures taken by cameras onboard Curiosity and shows details of the landscape along the rover’s route.

The full image is available with pan and zoom tools at http://mars.nasa.gov/bp1/.

NASA announces asteroid grand challenge

June 19, 2013

asteroid

NASA announced Tuesday a Grand Challenge focused on finding all asteroid threats to human populations and knowing what to do about them.

The challenge is a large-scale effort that will use multi-disciplinary collaborations and a variety of partnerships with other government agencies, international partners, industry, academia, and citizen scientists. It complements NASA’s recently announced mission to redirect an asteroid and send humans to study it.… read more

New step towards silicon-based quantum computer

June 19, 2013

unsw_quantum_clusters

Researchers at the University of New South Wales have proposed a new way to distinguish between quantum bits that are placed only a few nanometers apart in a silicon chip, taking them a step closer to the construction of a large-scale quantum computer.

Quantum bits, or qubits, are the basic building blocks of quantum computers — ultra-powerful devices that will offer enormous advantages for solving… read more

Unagi, the sea-going Japanese freshwater eel, harbors a fluorescent protein that could serve as the basis for a revolutionary new clinical test for bilirubin, a critical indicator of human liver function, hemolysis, and jaundice, according to researchers from the RIKEN Brain Science Institute.

Best known as a culinary delicacy in Japan, the freshwater eel Unagi (Anguilla japonica) and related species have seen a worldwide decrease… read more

Combining materials to make nanoscale 2D electronic components

June 19, 2013

Schematics and experimental images produced by Oak Ridge National Laboratory show defects at the 60-degree grain boundaries in two-dimensional samples of molybdenum disulfide. The defects are 5- and 7-atom dislocation cores; the numbers refer to locations where the atomic arrangements veer from regular six-atom hexagons. Their presence indicates a one-dimensional conductive “wire” that runs along the boundary. In the illustration, the molybdenum atoms are cyan and the sulfur atoms are orange and yellow. (Credit: Oak Ridge National Laboratory)

Scientists at Rice University and Oak Ridge National Laboratory (ORNL) have advanced on the goal of achieving two-dimensional electronics with a method to control the growth of uniform atomic layers of molybdenum disulfide (MDS).

MDS, a semiconductor, is one of three materials needed to make functioning 2D electronic components. The hope is that MDS could be joined with graphene, which has no band gap, and… read more

Faster, more precise airstrikes within reach

June 19, 2013

(credit:

Air-ground fire coordination—also known as Close Air Support or CAS—is a dangerous and difficult business. Pilots and dismounted ground agents must ensure they hit only the intended target using just voice directions and, if they’re lucky, a common paper map.

It can often take up to an hour to confer, get in position and strike — time in which targets can attack first or move out of reach. To… read more

An algorithm developed in EPFL’s School of Computer and Communications Sciences makes it possible to measure the dimensions and shapes of a room using just four microphones and a snap of your fingers.

“Our software can build a 3D map of a simple, convex room with a precision of a few millimeters,” explains PhD student Ivan Dokmanić.

Timothy Leary — transhumanism with a SMI2LE

Most people know Timothy Leary as the “LSD guru” who encouraged people to “Turn On, Tune In, Drop Out” in the 1960s. But a surprising number of transhumanist types don’t know that he was one of them.

In fact, Leary may have been the first to signal a memeplex for the transhuman future — SMI2LE (Space Migration Intelligence Increase and Life Extension) — back in the mid-1970s.

Dear Ray:

If the development of computer-based intelligence will become equivalent to that of human intelligence within the next twenty or thirty years, this computer-based intelligence will be able to build even better computers.

No doubt it will supersede the capacity of the human mind. This leads me to… read more
