Come on. It's for science.
In fact, it's meant to help people.
Researchers at Simon Fraser University in Burnaby, British Columbia, Canada, put a dead pig in a shark-proof (and octopus-proof, as you'll see) cage and stuck it in the ocean in order to learn more about how human remains decompose underwater. That knowledge will help forensic scientists interpret crime scenes.
Most of the work is done by maggots known as sea lice, but towards the end, after the maggots have eaten the good bits, you can watch some fat, red shrimp move in to pick apart the cartilage.

In 2009, the National Academies of Science published a massive report on forensics. For many Americans, forensics is possibly the most familiar of all the sciences. It's the one we welcome into our living rooms every night, along with TV crime dramas and murder mysteries. But the report's conclusions might surprise you.
For one thing, it's hard to even generalize about the state of forensic science in the United States, because everything from standard practices to accreditation varies widely by sub-discipline, law-enforcement agency, and whether the law enforcement is happening at a local, state, or federal level. Worse, it's not at all clear that some of those sub-disciplines have a sound, scientific basis. For instance, DNA analysis tends to be pretty well-supported by evidence, while fingerprint analysis remains an art, more dependent on the person looking at the fingerprint than on hard laws of anatomy. Of course, the report also found that there simply hasn't been enough research done to determine how scientific most disciplines of forensic science are to begin with. Meanwhile, the Supreme Court has allowed trial judges to certify forensic techniques as reliable even though we don't know whether they they are or not — and those decisions have been made in a haphazard, inconsistent way from one judge to the next.
Given how much our legal system relies on this stuff, we should all be feeling more than a little uncomfortable right about now. The state of forensic science, combined with its importance, virtually guarantees that there are innocent people behind bars (or worse) and criminals on the loose. Read the rest
Found by Vermont teacher Jon Noerr in a creek near Pharaoh Lake, a muddy Canon XT Rebel had clearly taken its last shot. But the memory card was ship-shape, and its contents made it possible to track owner Michael Comeau down and give him back his long-lost photos.
The memory card’s contents contained a hodgepodge of urban streetscapes, photos of apparent loved ones and random signs. He noticed most of the photos appeared to be in one general area, which he believed to be in one of New York City’s outer boroughs. ... But just two photos served as Noerr’s “holy grail,” a shot of a young woman sitting on a front stoop of a house numbered 327 and a shot taken seconds later of the sky that captured a street sign reading 3rd Street.

The story is familiar to us today: Somebody, usually a young man, walks into a public place, kills a bunch of people seemingly at random, and (usually) ends the murder spree with a suicide-by-cop.
But this story—at least, in Western culture—is startlingly new, relatively speaking. In fact, Paul Mullen, a forensic psychologist, says we can pin a date and place on the first time it happened. On September 4, 1913, in the German towns of Degerloch and Mühlhausen an der Enz, Ernst August Wagner killed his wife, his children, and at least nine strangers. He shot more than 20 people and set several fires during his killing spree. He ended up spending the rest of his life in an insane asylum.
But when we try to pin killings like these on mental illness, Mullen says, we're not quite hitting the right point. The people who go on killing sprees are mad, sure. But that's not the same thing as diagnosable, objective, physical mental illness. Only about 10% of the people ever arrested for crimes like this had actual mental illnesses. In fact, Mullen thinks these killings have more to do with culture than brain chemistry. His argument is interesting. And it might sound a little similar to the old "angry music made him do it!" trope. But what Mullen is talking about is different than that. Science journalist David Dobbs tries to explain the distinction:

I’m not saying the movies made Holmes crazy or psychopathic or some such. But the movies are a enormous, constant, heavily influential part of an American culture that fetishizes violence and glamorizes, to the point of ten-year wars, a militarized, let-it-rain approach to conflict resolution.
At Poynter, Craig Silverman writes about FourAndSix, a new photo forensics tool now in beta. The idea is to create tools that "sniff out digitally altered images." Two of the people behind it: Kevin Connor, former VP of product management for Adobe Photoshop, and digital image forensics expert Dr. Hany Farid. (via Erin Siegal) Read the rest
Last month, I read Deborah Blum's The Poisoner's Handbook , a really fascinating book about poison and murder in the early decades of the 20th century. Primarily, Blum looks at the development of forensic science and how the New York City coroner's office transitioned from being a place to stash political flunkies to being a scientific and effective player in crime solving. But there's another theme to the book as well—without science, there are many crimes that go not just unpunished, but completely unnoticed.
And this isn't just about women offing their husbands or villains chloroforming unsuspecting strangers. As the coroner's office developed standards of research and became an entity that served justice, the people who worked there became increasingly aware of the ways that the powerful profited off poisoning average workers and consumers. From government agents intentionally lacing alcohol with deadly adulterants during Prohibition, to factory owners knowingly exposing their workers to dangerous chemicals, Blum's book is full of examples of public corruption that was only brought to light because coroners took the time to apply the scientific method to investigating and cataloging deaths.
Some of these stories are ones I'd heard before, but had no idea the role that coroners and forensics had played in exposing the crime and providing evidence that ensured the people harmed received justice. For instance, Blum has a couple of posts on her blog right now about tetraethyl lead—the lead in "leaded" gasoline. This additive fixed an obnoxious mechanical problem in car engines, but at the price of sending factory workers to their deaths in straight jackets. Read the rest
