DIY prosthetics: the extreme athlete who built a new knee

Brian Bartlett lost his leg at 24. Rose Eveleth hears how a man who just wanted to ski again invented a new kind of knee.

When Brian Bartlett was 24 he was hit by a car from behind so hard it ripped his right leg off instantly. It all happened so fast. He doesn’t like to talk about it. “You really can’t understand,” he told me. “There’s just no way to…until you have an injury where you’re ripped or cut apart instantly.”

He turned 25 in the hospital. When he left, fitted above the knee with a prosthetic leg, he wanted to return to his life. Before the accident, Brian had been a competitive skier; he had a sponsorship, and he was on track for the US Olympic team. So after the accident, he was eager to get back to the slopes. It was 1998, long before Oscar Pistorius would take the track at the Olympics or Amy Purdy would take the stage on Dancing with the Stars.… Read the rest

Scientists have for the first time made a conclusive link between the 2010 BP oil spill in the Gulf of Mexico and an unprecedented dolphin die-off along the Gulf’s northern coast.

Bottlenose dolphins in Louisiana, Mississippi, and Alabama experienced an “unusual mortality event” beginning in February 2010 and continuing into 2014, according to the study, written by a team of 22 researchers, including scientists with the National Marine Fisheries Service, Audubon Nature Institute’s Aquarium of the Americas, the Louisiana Department of Wildlife and Fisheries, and a number of marine laboratories nationwide.

By comparing tissue samples from dead dolphins found along the northern Gulf of Mexico—including 22 from Louisiana’s Barataria Bay, one of the most heavily oiled coastal areas in the wake of the Deepwater Horizon disaster— with similar samples taken from dead dolphins found in the states that weren’t within the BP oil footprint, the scientists discovered that stranded and dead bottlenose dolphins within the spill range had lung and adrenal lesions consistent with petroleum product exposure.

Anti-Littering Campaign Uses DNA From Trash to Shame People

Big Brother is vacationing in Hong Kong, apparently. The South China Morning Post reports on an ad campaign in the former British colony that used the DNA of the litterbugs to create posters with their composite faces:

A campaign that used DNA analysis to give a face to anonymous Hong Kong litterbugs, then posted representations of the faces on billboards across the city, has been a big hit on social media.

The Face of Litter campaign was launched on Global Earth Day last month for the Hong Kong Cleanup Initiative, organised by online magazine Ecozine and the Nature Conservancy. It was aimed at raising awareness of the extent of littering in the city by pinpointing those responsible and encouraging people to change their behaviour…

Marketing communications agency Ogilvy & Mather Hong Kong came up with the idea for the billboard campaign and enlisted US-based  Parabon Nanolabs.

‘Freelance’ Spies Filling in for NSA, Recording Your Private Conversations

Now that the NSA is readying to shut down its domestic surveillance operation as the Patriot Act goes into limbo, some freelancers in New York City are picking up the NSA’s reins and recording private conversations at restaurants, gyms and other public locations. Generously, they are “declassifying” the recordings and publishing them at their website, WeAreAlwaysListening.com. Gothamist reports:

Thanks to Edward Snowden, we know that the National Security Agency collects the phone records of every American in order to keep the country safe from terrorism. But for the past eight months a group of artists claiming to work for the NSA on “a freelance, pro bono basis” have been recording people’s private conversations in popular bars, restaurants, and gyms in Lower Manhattan to ensure that no actionable intelligence falls through the cracks.

“We’re looking for terrorism, we’re looking for signs of plots and schemes that could put the homeland at risk,” one of the group’s “agents” tells us.

The Night Doctors: the terror behind the abduction phenomenon

Theo Paijmans writes a compelling analysis of the abduction phenomenon over at Mysterious Universe:

Do the roots of how we have come to perceive the UFO abduction phenomenon lie elsewhere, not between the stars but buried in the folklore and superstition of a suppressed people? If so, what does it tell us? Is the abduction phenomenon older than we think, does it manifest itself amongst the various cultures on earth in a different way? A hundred years ago you’d be having a very good chance that an African American, no matter where he might live in the United States, might mutter in agreement to all these questions, before hurrying off in utter fear.

Not too long ago large parts of the American population were the victim of a virulent racism, and, although the sharpest edges have been removed, it has never totally gone away. What this racism also brought with it was a unique divergence of the folkloric beliefs and superstitions of the various racial populations that made up America.

Philosophy Recap: Self-Knowledge

I love Stanford’s Encyclopedia of Philosophy, it’s a great resource. Here’s the introduction and table of contents to their entry on Self-Knowledge.

via Stanford Encyclopedia of Philosophy:

In philosophy, “self-knowledge” standardly refers to knowledge of one’s own sensations, thoughts, beliefs, and other mental states. At least since Descartes, most philosophers have believed that our knowledge of our own mental states differs markedly from our knowledge of the external world (where this includes our knowledge of others’ thoughts). But there is little agreement about what precisely distinguishes self-knowledge from knowledge in other realms. Partially because of this disagreement, philosophers have endorsed competing accounts of how we acquire self-knowledge. These accounts have important consequences for a broad range of philosophical issues, especially issues in epistemology and the philosophy of mind.

This entry focuses on knowledge of one’s own particular mental states. A separate topic sometimes referred to as “self-knowledge”, knowledge about a persisting self, is addressed in a supplement:Knowledge of the Self.
