The 2010 PopTech Conference wrapped up last weekend with a flurry of mind-blowing presentations by inventors, innovators, and intellectuals. This year’s theme was “brilliant accidents, necessary failures, and improbable breakthroughs.” Here are a few highlights from Saturday:

Simon Hauger and Azeem Hill showed off a project from West Philly, which not only teaches math and science through project-based education, but also makes some badass hybrid race cars (that beat MIT twice).

Asil Abulil, Nour Al-Arda, and Asil Shaar demonstrated a walking cane for the blind. The technology alone is impressive, but what’s even more extraordinary is that the three girls developed the technology at a UN-sponsored school for Palestinian refugees in the West Bank.

Riley Crane won the 2009 DARPA Network Challenge using the Internet and social networking to find 10 weather balloons that had been hidden around the country. He’s also applying the technology to address social problems, through projects like 1billionhungry.

Laura Poitras showed clips from her film trilogy about post-9/11 America. Then, she showed off the inexplicable slideshow that turned up on her computer after U.S. agents confiscated it for 40 days. Watch The Oath.

Chris Chabris is one the men behind the invisible gorilla experiment. He spoke about the illusion of memory and attention and how the least talented joke-tellers are the most overconfident in their joke-telling abilities.

Adrian Owen is a neurologist, who has been using fMRI to show how vegetative patients can respond to simple yes and no questions by igniting the same regions of the brain as healthy controls, which raises questions about both consciousness and end-of-life care.

Ben Goldacre covers bad science for the Guardian. He gave a very jittery and compelling presentation about the libel suit that was brought against him by a vitamin salesman, who once launched a pseudoscience campaign against antiretroviral drugs in South Africa.

David Eagleman said that people are tired of being certain about things they can’t possibly be certain about—particularly when it comes to religion and science. He said one alternative (which he inadvertently invented in 2007) is possibilianism.

    Reddit user Girlfriendhatesmefor’s three-year-old pitbull, Otis, had recently become overprotective of his wife. So he asked the online community if they knew what might be wrong with the dog.

    “A week or two ago, my wife got some sort of stomach bug,” the Reddit user wrote under the subreddit /r/dogs. “She was really nauseous and ill for about a week. Otis is very in tune with her emotions (we once got in a fight and she was upset, I swear he was staring daggers at me lol) and during this time didn’t even want to leave her to go on walks. We thought it was adorable!”

    His wife soon felt better, butthe dog’s behavior didn’t change.

    Girlfriendhatesmefor began to fear that Otis’ behavior may be an early sign of an aggression issue or an indication that the dog was hurt or sick.

    So he threw a question out to fellow Reddit users: “Has anyone else’s dog suddenly developed attachment/aggression issues? Any and all advice appreciated, even if it’s that we’re being paranoid!”

    The most popular response to his thread was by ZZBC.

    Any chance your wife is pregnant?

    The potential news hit Girlfriendhatesmefor like a ton of bricks. A few days later, Girlfriendhatesmefor posted an update and ZZBC was right!

    “The wifey is pregnant!” the father-to-be wrote. “Otis is still being overprotective but it all makes sense now! Thanks for all the advice and kind words! Sorry for the delayed reply, I didn’t check back until just now!”

    Redditors responded with similar experiences.

    Anecdotal I know but I swear my dog knew I was pregnant before I was. He was super clingy (more than normal) and was always resting his head on my belly.

    So why do dogs get overprotective when someone is pregnant?

    Jeff Werber, PhD, president and chief veterinarian of the Century Veterinary Group in Los Angeles, told Health.com that “dogs can also smell the hormonal changes going on in a woman’s body at that time.” He added the dog may “not understand that this new scent of your skin and breath is caused by a developing baby, but they will know that something is different with you—which might cause them to be more curious or attentive.”

    The big lesson here is to listen to your pets and to ask questions when their behavior abruptly changes. They may be trying to tell you something, and the news may be life-changing.

    Why mass shootings spawn conspiracy theories

    Mass shootings and conspiracy theories have a long history.

    While conspiracy theories are not limited to any topic, there is one type of event that seems particularly likely to spark them: mass shootings, typically defined as attacks in which a shooter kills at least four other people.

    When one person kills many others in a single incident, particularly when it seems random, people naturally seek out answers for why the tragedy happened. After all, if a mass shooting is random, anyone can be a target.

    Pointing to some nefarious plan by a powerful group – such as the government – can be more comforting than the idea that the attack was the result of a disturbed or mentally ill individual who obtained a firearm legally.
