Technology

+ - Piezoelectric system replicates muscle motion of human eye->

Submitted by Peristaltic
Peristaltic (650487) writes "Researchers at the Georgia Tech Bio-Robotics and Human Modeling Laboratory are using muscle-like piezoelectric actuators to mimic the motion of the human eye. While the device currently allows a single-degree of freedom, plans include a multi-degree of freedom device that accurately replicates human eye motion for use in robotic systems."

+ - Cyanide-producing GM grass linked to Texas cattle deaths->

Submitted by Peristaltic
Peristaltic (650487) writes "Scientists at the U.S. Department of Agriculture are trying to determine if an unexpected mutation in a popular GM grass, Tifton 85, is responsible for the sudden deaths of a small herd of cattle in Elgin, Texas three weeks ago. The grass has been used for grazing since 1992 without incident, however after a severe drought last year in Texas, the grass started producing cyanide in sufficient quantities to kill a small herd of cattle in Elgin, Texas. Testing has found the cyanide-producing grass in nearby fields as well.

This latest incident once again highlights the debate regarding the benefits vs. the risks of using gmo in agriculture"

Apache

+ - Apache vs. Open Source->

Submitted by Peristaltic
Peristaltic (650487) writes "Does the Apache Software Foundation still embody the values championed at its inception 12 years ago, or has it evolved to more closely resemble the corporate bureaucracies from which it has tried to distance itself? There seems to be a growing consensus for the latter. From the article:

The problem here is less about git and more about the chasm between Apache and the new culture of open source. There is a growing community of young new open source developers that Apache continues to distance itself from and as the ASF plants itself firmly in this position the growing community drifts farther away.

Hardware Hacking

+ - Methods of learning to build electronic circuitry?

Submitted by Peristaltic
Peristaltic (650487) writes "I've seen some cool articles in Instructables detailing how to create various electronic gadgets. A couple of these as well as the odd DIY kit have come to life on my kitchen table. While it's satisfying to see the things work after time spent soldering, I would love to be able to take the next step beyond the basics of component functionality, i.e. a resistor does this; a capacitor does that. Forest Mimm's books have been helpful towards this end...but it's time to move forward. Every month or so, I read here on Slashdot a plea for help getting started with, or expanding someone's knowledge of programming. O.k., I'd like to make that plea for help with electronics theory & circuit building. I've found plenty of references on the web, Amazon, etc., but can someone who's already taken this trip outline what has and hasn't worked for them?"
