Submission + - SPAM: Breakthrough increases plant yields by one third

schwit1 writes: Plant scientists have found a way to encourage plants to better use atmospheric nitrogen, thus increasing yields by more than one third.

For years, scientists have tried to increase the rate of nitrogen fixation in legumes by altering rhizobia bacterioid function or interactions that take place between the bacterioid and the root nodule cells.

Tegeder took a different approach: She increased the number of proteins that help move nitrogen from the rhizobia bacteria to the plant’s leaves, seed-producing organs and other areas where it is needed. The additional transport proteins sped up the overall export of nitrogen from the root nodules. This initiated a feedback loop that caused the rhizobia to start fixing more atmospheric nitrogen, which the plant then used to produce more seeds. “They are bigger, grow faster and generally look better than natural soybean plants,” Tegeder said. “Some evidence we have suggests they might also be highly efficient under stressful conditions like drought.”

The technique not only produces healthier plants and more seeds, it reduces the need for fertilizer, the overuse of which can be an environmental issue.

Submission + - SPAM: Ignorant of Streisand Effect, YouTube restricts Trump's video

mi writes: In an attempt to limit its impact, YouTube's censors have placed "unlisted" Trump's anti-Clinton video and then made it inaccessible in the "restricted" mode.

Predictably, the efforts backfired and the video was seen by over 370K times within 24 hours — seemingly a record for the "Team Trump" channel.

At the time of this typing, all restrictions have been removed from the video.

Submission + - Ask slashdot: What to buy? 3

yenrabbit writes: I'm from Zimbabwe, and a combination of sanctions, reluctant parents and a low budget have meant that, until now, I have been unable to buy anything online. That's just changed, and I've got an opportunity to get a few hundred bucks of stuff ordered online. But the question is WHAT? A rhaspberry pi is a definite, but beyond that I turn to you, slashdot. Should I get books? Arduino? In short what are the absolute essentials for a money-starved nerd in Africa?

Submission + - Algorithm Brings Speedier, Safer CT Scans (

kenekaplan writes: Standard CT scanners can generate images of patient's body in less than five minutes today, but the radiation dose can be equal to about 70 chest X-rays. Lower powered CT scans can be used in non-emergency situations, but it can take more than 4 days to produce those images. Intel and GE created an algorithm that speeds up a computer's ability to process the low radiation dose scans by 100x, from 100 hours per image to 1 hour.

Submission + - Why Monsanto didn't expect Roundup-resistant weeds 2

jenningsthecat writes: From NPR comes the story of how Monsanto thought Roundup was "a herbicide with low risk for weed resistance." The explanation seems to pretty much boil down to "we had a hell of a time creating Roundup-resistant crops, so we figured Mother Nature had little or no chance".

In the face of Monsanto's hubris, Mother Nature went ahead and made 20 strains of weeds, (so far), tolerant to glyphosate. Good for her!

gotfork writes: "As some Russians protest the results of the recent election, several commentators (Russian, English) have started looking at the results which are posted to the election commission web site and there's very strong evidence of fraud. Voter turnout correlates strongly with percent voting for the ruling party, United Russia, and there are a lot of polling stations with nearly 100% turnout and 100% voting for United Russia in some unusual places. The raw data is posted so you can do your own analysis."

loic_2003 writes: "Iranian TV has broadcast footage of an advanced US drone aircraft that Tehran says it brought down using electronic methods to override its controls.
The BBC's James Reynolds watched the footage and said the fact that the drone appeared undamaged provided some evidence to support Tehran's version of events.
The film was captioned "RQ170 — advanced US spy plane" and carried on the Vision of the Islamic Republic of Iran Network 1 channel."

Asmodae writes: An LHC Experiment sending neutrinos to a detector in Italy found a discrepency, the neutrinos were arriving early. So early in fact that they appear to be moving faster than the speed of light. They've done a lot of measurements, but the findings are significant enough that the researchers remain cautious

intellitech writes: "Puzzling results from Cern, home of the LHC, have confounded physicists — because it appears subatomic particles have exceeded the speed of light. Neutrinos sent through the ground from Cern toward the Gran Sasso laboratory 732km away seemed to show up a few billionths of a second early. The results will soon be online to draw closer scrutiny to a result that, if true, would upend a century of physics. The lab's research director called it "an apparently unbelievable result"."

LibRT writes: The technology allows vehicles to mimic the temperature of their surroundings.

It can also make a tank look like other objects, such as a cow or car, when seen through heat-sensitive 'scopes.

Researchers are looking at ways to make it work with other wavelengths of light to confer true invisibility.


Submission + - Iron Man-like Exoskeleton Nears Production (

fangmcgee writes: By now, with films like Iron Man, its sequel, and Avatar, Hollywood has made us thoroughly familiar with the idea of the robotic exoskeleton. Less well known, however, is that researchers are actually building robotic exoskeletons like the ones envisioned by Hollywood and the comic book visionaries from whom Hollywood pilfers its most lucrative ideas. Among the developers of real-life Iron Man suits (of which there are many, the world over) is a group called Raytheon Sarcos. And as IEEE Spectrum reports in this month's issue, its impressive second-generation exoskeleton robotics suit, dubbed the XOS 2, is nearing production.

When the project–named “Turn the Pearl River Delta into One”–is completed some six years from now, the resulting megacity will cover 40,000 square kilometers (16,000 square miles) and, by today’s numbers, reach a population of at least 42 million."

RedEaredSlider writes: "Ford is using Google technology, specifically its Prediction API, to create a new brand of smart cars. The famous American car company announced it's teaming up with Google to use Prediction API in future cars. The API will be able to use historical driving data and turn it into real time predictions, such as where a driver is headed at the time of a departure. The API uses Google's machine learning algorithms to "make smarter apps smarter.""
