Light-activated brain-machine interface

Researchers develop ‘wireless’ activation of brain circuits
“The long-term goal of this work is to develop a light-activated brain-machine interface that restores function following nerve or brain impairments,” Strowbridge says. “The first attempts to interface computers with brain circuitry are being done now with complex metal electrode stimulation arrays that are …

Gravity Probe B Secures Alternative Funding To Complete Science

================================
GP-B STATUS UPDATE — September 26, 2008
================================
Since our May 23rd status update, GP-B has continued to make
significant progress–fiscal and scientific. NASA funding and
sponsorship of the program ends on September 30, 2008, but GP-B has
secured alternative funding that will enable our science team to
continue working at least through December 2009 in …

We Command the Lightning’s Hand

A little Science Friday fun for those Trailing Boomers who might recall that dreaded Kansas epic anthem.

Duly noted: sometimes only the top half of the first video frame is loading on initial page load. If video is started, launched to full screen, then returned to embed; that fixes it. …

What if all our something is actually the larger context’s nothing?

What if the vast majority of matter turns out to be dark matter and everything we are ever capable of observing turns out to be the minority missing bits from the dominant dark’s perspective? These questions are externalities to the actual subject of the posted article, but in any case:
Good …

Gravity Probe B Update

For those who have been too busy to keep track, our colleagues at GP-B have indeed overcome innumerable obstacles over the course of “the longest running, continuous physics research program at both Stanford and NASA.”
As is so often the case in science, the political battles required to sustain sufficient resources …

Tandem Quantum Teleportation and Memory

Excerpt: Researchers Demonstrate Quantum Teleportation and Memory in Tandem
In research that may be a key step toward real-life quantum communication—the transmission of information using atoms, photons, or other quantum objects—researchers created an experiment in which a quantum bit of information is transported across a distance of seven meters and briefly …

Please Debunk These Equations and Expositions

Discovery of the Unified Field. Really? Unquestionably? Close enough to be worthy of some continued consideration, or wholly falsifiable and empirically disproved either mathematically, experimentally, or by both?
I don’t have anywhere near the math skills required to prove or disprove the equations below. I don’t possess anywhere near the …

Nanotechnology on KQED QUEST

This 10 minute introductory segment aired last year on QUEST, but it sure beats reruns during the current writer’s strike.

Gravity Probe B Update

Very Exciting! We attended the previous public presentation in April when Professor Francis Everitt, a very approachable Stanford University physicist and principal investigator of the Gravity Probe B (GP-B) Relativity Mission and his team, “shared what they have found so far—namely that the data from the GP-B gyroscopes clearly confirm …

South Dakota + Grinning Scientists + Abandoned Mine + Secret Underground Fort

Better sick the Area 51 watchers on this one, pronto! But seriously:
Neutrinos move at nearly the speed of light, scientists say, and cosmic radiation, a sort of clutter, makes it difficult to study them at the earth’s surface. Deep underground, there’s less clutter or static.
