ananyo writes "A genetic-modification technique used widely to make crops herbicide resistant has been shown to confer advantages on a weedy form of rice, even in the absence of the herbicide. Used in Monsanto's 'Roundup Ready' crops, for example, resistance to the herbicide glyphosate enables farmers to wipe out most weeds from the fields without damaging their crops. A common assumption has been that if such herbicide resistance genes manage to make it into weedy or wild relatives, they would be disadvantageous and plants containing them would die out. But the new study led by Lu Baorong, an ecologist at Fudan University in Shanghai, challenges that view: it shows that a weedy form of the common rice crop, Oryza sativa, gets a significant fitness boost from glyphosate resistance, even when glyphosate is not applied. The transgenic hybrids had higher rates of photosynthesis, grew more shoots and flowers and produced 48 — 125% more seeds per plant than non-transgenic hybrids — in the absence of glyphosate, the weedkiller they were resistant to."

Do you want to be frozen after you die, in hopes of being revived a century or two (or maybe ten) in the future? It can cost less than an electric car. That's what the Cryonics Institute (CI) offers. David Ettinger, today's interviewee, is both the son of CI founder Robert Ettinger and CI's lawyer. In this video, among other things, he talks about arrangements that were made for his father's demise, and how they were able to start the cryopreservation process almost immediately after he expired. Is Cryonics the best chance at immortality for those of us likely to die before the Singularity arrives, and gives all of us the tools we need to live forever? David Ettinger obviously thinks so. (This is Video #1 of 2. The second one is scheduled to run tomorrow. It's an interview with CI Director Andy Zawacki, who takes us into the facility where the frozen bodies are stored.)

coondoggie writes "In the never-ending quest to get computers to process, really understand and actually reason, scientists at Defense Advanced Research Projects Agency want to look more deeply into how computers can mimic a key portion of our brain. The military's advanced research group recently put out a call, or Request For information, on how it could develop systems that go beyond machine learning, Bayesian techniques, and graphical technology to solve 'extraordinarily difficult recognition problems in real-time.'"

cylonlover writes "Astronauts on the International Space Station (ISS) are testing a new propulsion system ... inside the station. While this might seem like the height of recklessness, this particular system doesn't use rockets or propellants. Developed in the University of Maryland's Space Power and Propulsion Laboratory, this new electromagnetic propulsion technology called the Resonant Inductive Near-field Generation System (RINGS) uses magnetic fields to move spacecraft as a way to increase service life and make satellite formation flying more practical."

Hugh Pickens DOT Com writes "Celso Perez and Muneer Ahmad write in The Atlantic that despite evidence to the contrary, for nearly three years, the United Nations has categorically denied that it introduced cholera into Haiti after the country suffered a devastating earthquake in 2010. Since then, cholera has killed more than 8,000 people and infected more than 600,000, creating an ongoing epidemic. According to extensive documentation by scientists and journalists, peacekeeping troops belonging to the UN Stabilization Mission in Haiti (MINUSTAH) inadvertently but negligently brought cholera into the country several months after the January 2010 earthquake. That October, troops from Nepal carrying the disease were stationed at a military base near the town of Méyè. Because of inadequate water and sanitation facilities at the base, cholera-infected sewage contaminated the Artibonite River, the largest river in Haiti and one the country's main water sources. As locals consumed the contaminated water, cholera spread across the country. Absent from Haiti for over a century, cholera is now projected to plague the country for at least another decade. 'By refusing to acknowledge responsibility, the United Nations jeopardizes its standing and moral authority in Haiti and in other countries where its personnel are deployed,' writes the Washington Post Editorial Board adding that without 'speaking frankly about its own responsibility for introducing cholera to Haiti, the organization does a disservice to Haiti and Haitians, who deserve better.'"
