Who Farts? And Who Cares? "Sociologists Martin Weinberg and Colin Williams wanted to know. They and their team interviewed 172 college students about their habits and concerns about farting and pooping. They published their results in an article called Fecal Matters.

"Is organic produce better for you?" is a simple question asked by a middle schooler in a science fair. Using fruit flies fed organic vs. conventional produce, Ria Chhabra tracked the flies and saw improvements based on their diet. Now barely a sophomore in high school, the project lead to university research labs, science fair awards, publication in top-tier peer-reviewed journals, and quite likely, scholarships at her pick of top-flight universities.
The Virtual Power Plant: "Critics of renewables have always claimed that sun and wind are only intermittent producers of electricity and need fossil fuel plants as back-up to make them viable. But German engineers have proved this is not so." A pilot program funded by the German Federal Ministry of the Environment offers a rebuttal to critics who claim renewable energy sources have an insurmountable variability problem.
Is it time to put natural selection in its place? Jello Biafra once famously wrote that "If evolution is outlawed, only outlaws will evolve." But while it likely comes as no surprise to specialists working in the field or to those who've been following developments in evolutionary biology closely, there's an emerging view among experts that Darwin's view of natural selection as the primary driver of speciation and evolutionary change may be incorrect or at least drastically overstated. It's long been understood that non-adaptive evolutionary mechanisms like "genetic drift" and random mutation also play non-trivial roles in evolutionary processes, but a recent study (link to abstract with full-text PDF available) casts new doubts on the primary role of natural selection, finding that "Neutral models, in which genetic change arises through random variation without fitness differences have proven remarkably successful in describing observed patterns of biodiversity."

NASA recently announced that the latest results from NASA's Curiosity Rover on Mars provide clear physical evidence that Mars once had all the conditions necessary to support life. Despite the skeptical reception given to recent news that the rover may also have found indirect evidence of organic compounds and active microbiological activity, other recent scientific results have gone even further. One Australian study from 2011 concluded, given what we know about Mars now, 3% of its total volume (as compared to 1% of Earth's) is likely habitable to known terrestrial lifeforms. And more recently, further analysis of the results of experiments performed by the 1976 Viking Lander mission suggests that we have likely detected active microbiological activity on Mars already, with one researcher going so far as to claim a 99% certainty that those earlier results detected life.

12-year-old uses Dungeons & Dragons to help scientist dad with his research: Cognitive scientist Alan Kingstone wanted to test whether people look at each others' eyes or simply to the center of faces. Some had suggested an answer would be impossible to discern because humans' eyes are in the center of their faces. But Alan’s son, Julian, a fan of D&D, told his father about D&D monster characters that have eyes in unusual places, such as on their hands or tail. “[Julian suggested] if you just showed them these images, you could find out whether they are looking for the eyes or not. I thought, actually, that’s a very good idea,” Kingstone said (summarized from Cosmos). The paper describing the results - "Monsters are people too" - was published in the British Royal Society journal Biology Letters this month, with 14-year-old Julian named as the lead author.

The broth is just chicken and onions, with a confetti of vegetables added at the end where their flavor remains bright. The noodles are wide and winding... But, for me, the real triumph was giving the chicken parts and onion a saute... before adding water to make the soup. This deepened flavor base makes for magical soup, with a bronzed color, more robust flavor and significantly reduced prep time. ... With all of the blustery, cold days to go this winter, everyone... deserves to have a homemade, from-scratch chicken noodle soup that can be pulled off in just about an hour in their back pocket.

In the late 1970s the UK's Anglia Television ran a respected weekly documentary series: Science Report. But when the show was cancelled in 1977, the producers decided to channel Orson Welles in their final episode. The result was Alternative 3. Over the course of the hour, the audience would learn that a Science Report investigation into the UK "brain drain" had uncovered shocking revelations: man-made pollution had resulted in catastrophic climate change, the Earth would soon be rendered uninhabitable, and a secret American / Soviet joint plan was in place to establish colonies on the Moon and Mars. The show ended with footage of a US/Soviet Mars landing from May 22, 1962. After Alternative 3 aired, thousands of panicked viewers phoned the production company and demanded to know how long they had left to change planets. [more inside]

In 1973 and 1975, two one-hour television documentaries aired in the US: In Search of Ancient Astronauts (Parts: 1, 2, 3, 4, 5, 6) and In Search of Ancient Mysteries (Parts: 1, 2, 3, 4, 5, 6). The same producers also put out The Outer Space Connection (Parts 1 and 2) in 1975. All were narrated by Twilight Zone's Rod Serling. In 1976 a series was developed. Since Serling had passed away in 1975, popular actor Leonard Nimoy was chosen as host. In Search of... ran for six seasons, from 1976 - 1982, and was devoted to discussing unusual mysteries and phenomena. All 144 episodes can be seen on YouTube. Playlists: Seasons 1 and 2. Seasons 3 and 4. Seasons 5 and 6.
The BBC has produced a fabulous infographic showing the ocean zones: Sunlight, Twilight, Midnight, Lower Midnight, and The Trenches. The page also includes videos showing: what happens to material at 100, 1000, and 10,000 meters down; the animals living in the Abyssal Plains (described in a lovely Scottish accent); and the story of Jacques Piccard and Don Walsh going down to the Mariana Trench in 1960. No one has been back there since, but director James Cameron and Richard Branson are among the contenders who are going to make a go of it. (Rumour has it that Cameron intends to be the sole person in the sub, while Branson is just financing a team.) Meanwhile, the Doer team (backed by Eric Schmidt of Google), says it's all about the science and not just being first in this century's race. And there's even a yellow submarine for the rest of us, if by "rest of us" one means "has $250,000 to spare for a single trip". Don't forget to click the links at the top of the infographic page to see everything.
