Submission + - SPAM: Yuan Longping dies; rice research helped feed world

An anonymous reader writes: Yuan Longping, a Chinese scientist who developed higher-yield rice varieties that helped feed people around the world, died Saturday at a hospital in the southern city of Changsha, the Xinhua News agency reported. He was 90.

Yuan spent his life researching rice and was a household name in China, known by the nickname “Father of Hybrid Rice.” Worldwide, a fifth of all rice now comes from species created by hybrid rice following Yuan’s breakthrough discoveries, according to the website of the World Food Prize, which he won in 2004.

It was in the 1970s when Yuan achieved the breakthroughs that would make him a household name. He developed a hybrid strain of rice that recorded an annual yield 20% higher than existing varieties — meaning it could feed an extra 70 million people a year, according to Xinhua.

His work helped transform China from “food deficiency to food security” within three decades, according to the World Food Prize, which was created by Nobel Peace Prize laureate Norman Borlaug in 1986 to recognize scientists and others who have improved the quality and availability of food.

Even in his later years, Yuan did not stop doing research. In 2017, working with a Hunan agricultural school, he helped create a strain of low-cadmium indica rice for areas suffering from heavy metal pollution, reducing the amount of cadmium in rice by more than 90%.

Submission + - How Dinosaurs Shrank and Became Birds (quantamagazine.org)

An anonymous reader writes: Discoveries have shown that bird-specific features like feathers began to emerge long before the evolution of birds, indicating that birds simply adapted a number of pre-existing features to a new use. And recent research suggests that a few simple changes — among them the adoption of a more babylike skull shape into adulthood — likely played essential roles in the final push to bird-hood. Not only are birds much smaller than their dinosaur ancestors, they closely resemble dinosaur embryos. Adaptations such as these may have paved the way for modern birds’ distinguishing features, namely their ability to fly and their remarkably agile beaks. The work demonstrates how huge evolutionary changes can result from a series of small evolutionary steps.

Submission + - How many hoaxes are on Wikipedia? No one knows.... 2

An anonymous reader writes: The Washington Post's Caitlin Dewey has written a lengthy feature covering one of Wikipedia's most intractable problems: carefully inserted hoax information that is almost impossible to detect. Dewey's investigation starts with the recent discovery of the nonexistent Australian god "Jar’Edo Wens" (which lasted almost ten years), and discusses a Wikipediocracy post about a recent experiment by critic Greg Kohs, in which 30 articles received cleverly-chosen minor falsehoods. More than half survived for more than two months. Included is also a chart showing that editing participation in Wikipedia has "atrophied" since 2007. It is quite rare to see a feature in a major media outlet as critical as this, of Wikipedia and its little-known internal problems. Especially on the heels of a very favorable CBS 60 Minutes report. As Kohs says, “I think this has proved, beyond a reasonable doubt, that it’s not fair to say Wikipedia is ‘self-correcting,’”

Submission + - How Google has been implenting "Forget Me" requests. (cnn.com)

gurps_npc writes: CNN Money has a short, interesting piece on the results of Google's implementing Europe's "Right to be Forgotten".

They are denying most requests, particularly those made by convicted criminals, but are honoring the requests to remove salacious information — such as when a rape victim requested the article mentioning her by name be removed from searches for her name.

All in all, they seem to be doing a good job of respecting privacy, the law, and free speech.

Submission + - The latest Wikipedia code-word for "dysfunction" is "Superprotection" 3

metasonix writes: As if the problems brought up during the recent 2014 Wikimania conference weren't enough, now Wikipedia is having an outright revolt by its editor and administrator community, especially on the German-language Wikipedia. A new Wikipediocracy blog post goes into some detail on the story. The WMF, currently awash in cash from its donors, keeps trying to force flawed new software systems onto the community, and they have repeatedly responded very negatively. This time, however, WMF Deputy Director Erik Moeller had the bright idea to create a new level of page protection to prevent the new software from being disabled. "Superprotection" has resulted in an outright revolt on German Wikipedia and subsequent coverage in the German press, plus demands that Moeller, one of Wikipedia's oldest insiders, be removed from his job. And one English Wikipedia insider started a change.org petition demanding the removal of "superprotection".

Submission + - Jimmy Wales Embarrasses Himself at Wikimania

metasonix writes: On Sunday the 2014 Wikimania conference in London closed. Wikimania is the major annual event for Wikipedia editors, insiders and WMF employees to meet face-to-face, give presentations and submit papers. Usually they are full of "Wiki-Love" and good feelings; but this year, as the Wikipediocracy blog summarized, Wikipedia and its "god-king" Jimmy Wales came under considerable fire from the UK media — a very unusual occurrence. And much of it was direct criticism of Wales himself, including a very hostile interview by BBC journalist James O'Brien, who had been repeatedly defamed in his Wikipedia biography by persons unknown.

Submission + - Phase-changing material for Robots.

rtoz writes: In the movie "Terminator 2," the shape-shifting T-1000 robot morphs into a liquid state to squeeze through tight spaces or to repair itself when harmed.

Now a phase-changing material built from wax and foam, and capable of switching between hard and soft states, could allow even low-cost robots to perform the same feat.

The material developed by MIT researchers could be used to build deformable surgical robots. The robots could move through the body to reach a particular point without damaging any of the organs or vessels along the way.

The Robots built from this material could also be used in search-and-rescue operations to squeeze through rubble looking for survivors.

Submission + - German Wikipedia Has Problems With Paid Editing -- And Threats Of Violence 2

metasonix writes: As German journalist Marvin Oppong learned recently, there are a number of people who work to make articles about certain corporations and trade groups on German Wikipedia "look better". And when Oppong published his discoveries, one reaction was an openly violent threat, aimed at him, posted on de-WP's "Kurier" noticeboard. Just as with English Wikipedia, it is apparently a "terrible crime" to criticize German Wikipedia, even when Jimbo Wales's "bright line" rule on paid editing is being violated. Unlike English WP, the Germans will threaten to "curbstone" people for saying it.

Submission + - Major Wikipedia donors caught editing their own articles 7

An anonymous reader writes: As reported before on Slashdot, one of the most terrible sins on Wikipedia is to edit articles for pay, or otherwise violate the "neutral point of view" policy, per their co-founder Jimmy Wales. And yet, the Wikipedia-criticism website Wikipediocracy has recently performed a study showing that a large percentage of the Wikimedia Foundation's largest cash donors have violated that policy. Repeatedly, and wantonly. In short, they wrote articles about themselves or their companies, then gave the WMF big donations — and were not confronted about violating the NPOV policy. It reeks of outright favoritism. The first installment of an upcoming multi-part series discusses the co-creator of Cards Against Humanity, and his blatant editing of the Wikipedia article about his card game, followed by a $70,000 donation to the WMF. An honest donation, or hush money?

Submission + - What should we do about Wikipedia's porn problem? (larrysanger.org) 3

Larry Sanger writes: "In 2011, the Wikimedia Board committed to installing a "controversial content" filter even weaker than Google's SafeSearch, as proposed by the "2010 Wikimedia Study of Controversial Content." Since then, after growing opposition by some Wikipedians, some board members have made it clear that they do not expect this filter to be finished and installed. Nevertheless, as TFA makes clear, Wikipedia continues to host an enormous amount of extremely gross porn and other material most parents don't want their kids stumbling across. And this content is some of the website's most-accessed. Nevertheless, children remain some of Wikipedia's heaviest users. Jimmy Wales has recently reiterated his support for such a filter, but no work is being done on it, and the Foundation has not yet issued any statement about whether they intend to continue work on it."
