Completely Paralyzed Man Walks In Robotic Exoskeleton

Slashdot - 35 min 29 sec ago
Zothecula writes: Working with a team of UCLA scientists, a man with protracted and complete paralysis has recovered sufficient voluntary control to take charge of a bionic exoskeleton and take many thousands of steps. Using a non-invasive spinal stimulation system that requires no surgery, this is claimed (abstract) to be the first time that a person with such a comprehensive disability has been able to actively and voluntarily walk with such a device.

Slowing Wind Energy Production Suffers From Lack of Wind

Slashdot - 1 hour 17 min ago
HughPickens.com writes: Gregory Meyer reports at the Financial Times that electricity generated by U.S. wind farms fell 6 per cent in the first half of the year, even as the nation expanded wind generation capacity by 9 per cent. The reason was some of the softest air currents in 40 years, cutting power sales from wind farms to utilities. The situation is likely to intensify into the first quarter of 2016 as the El Niño weather phenomenon holds back wind speeds around much of the U.S. "We never anticipated a drop-off in the wind resource as we have witnessed over the past six months," says David Crane. Wind generated 4.4 per cent of US electricity last year, up from 0.4 per cent a decade earlier. But this year U.S. wind plants' "capacity factor" has averaged just a third of their total generating capacity, down from 38 per cent in 2014. EIA noted that slightly slower wind speeds can reduce output by a disproportionately large amount. "Capacity factors for wind turbines are largely determined by wind resources," says a report from the Energy Information Administration. "Because the output from a turbine varies nonlinearly with wind speed, small decreases in wind speeds can result in much larger changes in output and, in turn, capacity factors." In January of 2015, wind speeds remained 20 to 45 percent below normal on areas of the west coast, but it was especially bad in California, Oregon, and Washington, where those levels dropped to 50 percent below normal during the month of January.

How To Build With Delrin and a Laser Cutter

Slashdot - 2 hours 3 min ago
szczys writes: Laser cutters are awesome, but you have to bring your mechanical engineering A-game if you want to build resilient stuff using laser-cut parts. Joshua Vasquez has been building up his bag of tricks using Delrin and a laser cutter to build with techniques like press-fitting, threading, snap-fits, etc. that aren't possible or are non-ideal with the laser-cutting steadfasts of plywood and acrylic. Delrin (PDF) won't shatter like acrylic, and it has more give to it, so even the less precise entry-level lasers can cut joints that will have a snug fit.

Sultan of Sound, Dr. James Flanagan, Passed Away Aged 89

Slashdot - 2 hours 47 min ago
An anonymous reader writes: A pioneer in the field of acoustics, Dr. James L. Flanagan provided "the technical foundation for speech recognition, teleconferencing, MP3 music files, and the more efficient digital transmission of human conversation." The NYTimes covered his recent passing: "His innovations included preserving the sound of a human voice while crunching it digitally, as well as teaching computers to articulate — converting sound waves into digital pulses. He also helped devise a 'force-feedback' tactile glove, similar to today’s video game accessories, that enabled medical students to simulate hands-on examinations when a live patient or cadaver was not available (or to mimic a game of handball). Dr. Flanagan also played a minor role in the drama surrounding the downfall of President Richard M. Nixon." An older (2005) article from IEEE Spectrum titled "Sultan of Sound" provides background on his work and impact. An interview (1997) discussing his WWII service, research at AT&T Bell Labs & Rutgers University is part of the IEEE oral history series.

Ecologists wondering where the lions, and other top predators, are

Science Daily - 3 hours 4 min ago
Ecologists have discovered a pattern that is consistent across a range of ecosystems. They found that, in a very systematic way, in crowded settings, prey reproduced less than they do in settings where their numbers are smaller. Some scientists are already suggesting that it may well be the discovery of a new law of nature.

Fighting explosives pollution with mutant plants

Science Daily - 3 hours 5 min ago
Biologists have taken an important step in making it possible to clean millions of hectares of land contaminated by explosives. Biologists have unraveled the mechanism of TNT toxicity in plants raising the possibility of a new approach to explosives remediation technology. TNT has become an extensive global pollutant over the last 100 years and there are mounting concerns over its toxicity to biological systems.

Survey: More Women Are Going Into Programming

Slashdot - 3 hours 30 min ago
itwbennett writes: We've previously discussed the dearth of women in computing. Indeed, according to U.S. Bureau and Labor Statistics estimates, in 2014 four out of five programmers and software developers in the U.S. were men. But according to a survey conducted this spring by the Application Developers Alliance and IDC, that may be changing. The survey of 855 developers worldwide found that women make up 42% of developers with less than 1 year of experience and 30% of those with between 1 and 5 years of experience. Of course, getting women into programming is one thing; keeping them is the next big challenge.

Hubble survey unlocks clues to star birth in neighboring galaxy

Science Daily - 4 hours 4 min ago
In an intensive citizen-science-aided survey of Hubble telescope images of 2,753 young, blue star clusters in the neighboring Andromeda galaxy (M31), astronomers have found that M31 and our own galaxy have a similar percentage of newborn stars based on mass. By nailing down what percentage of stars have a particular mass within a cluster (the Initial Mass Function), scientists can better interpret the light from distant galaxies and understand the formation history of stars in our universe.
