Scientists show you can collect DNA from the air
Scientists have shown that you can collect DNA from the air, opening new ways to study airborne diseases and investigate crimes.
Family Tree DNA offers to trade privacy to catch criminals
The at-home DNA testing company Family Tree DNA is asking customers to share their genetic data to help law enforcement solve crimes. A video featuring Ed Smart, the father of kidnapping victim Elizabeth Smart, attempts to frame the sharing of its genetic database with FBI as a positive. According to MIT Technology Review, the video will air as an ad in San Diego, where police were recently able to solve a 1979 murder after finding a link in a publicly available DNA database. The ad is part of a larger campaign featured prominently on Family Tree DNA's website.
Police are using ancestry sites to track down more cold case suspects
In April, California investigators arrested Joseph James DeAngelo for some of the crimes committed by the elusive Golden State Killer (GSK), a man who is believed to have raped over 50 women and murdered at least 12 people between 1978 and 1986. Investigators tracked him down through an open-source ancestry site called GEDMatch, uploading the GSK's DNA profile and matching it to relatives whose DNA profiles were also hosted on the website. Now, using those same techniques, a handful of other arrests have been made for unsolved cases, some going as far back as 1981.
New York City ordered to share code for DNA evidence software
Many attempts to open up access to software in the justice system have fallen flat. Advocates in New York, however, have just scored a significant victory. A federal judge has publicly unsealed the source code for DNA analysis software previously used in New York City's crime lab, Forensic Statistical Tool, after ProPublica motioned for its disclosure. There are concerns that the software may have sent innocent people to prison by incorrectly determining that a suspect's DNA was likely to be part of a mix of genetic material (such as the handle of a gun). Public access to the code could theoretically catch flaws in the methodology and clear someone's name.

'Spider-Man: Homecoming' Is One of the Best Superhero Movies in Years Christopher Orr, The Atlantic Well folks, the time has come. The team-up between Sony and Marvel for the third different take on Spider-Man debuted this week. So far, the reviews are mostly positive, noting that the duo created a compelling story line for Peter Parker with Tom Holland that establishes the character in the Marvel Cinematic Universe. Don't take my word for it, The Atlantic has a full review (yep, spoilers) with all the details.
VR model of Auschwitz helps convict Nazi war criminal
German police have used VR forensics tech to prosecute a Nazi war criminal who worked at the Auschwitz-Birkenau concentration camp. The team from the Bavarian state crime office (LKA), led by investigator Ralf Breker, created highly detailed digital models of the facility using maps from a Warsaw surveyor's office and over a thousand period photos. Using an HTC Vive headset, they were then able to see exactly what the accused would have seen at the time.
Police could soon identify you by your hair proteins
Police and archaeologists regularly depend on DNA evidence for identification, but it has a serious flaw. DNA degrades under environmental conditions like heat and light, so it may be useless even if you have a ton of samples. However, Lawrence Livermore researchers have a better way: they've established a method of identifying humans based on hair protein markers. The markers are much more resilient than DNA (scientists found markers in remains about 250 years old) while remaining unique, with no one person sharing the same marker count and patterns. You only need a few hairs to get a result, too, and the ultimate goal is to pinpoint someone using a single strand of hair.
Electron microscopes stop thieves from covering their tracks
Ask the police and they'll tell you that serial numbers seldom help catch thieves -- dedicated crooks are usually smart enough to file off those digits so that stolen items can't be linked to a crime. Researchers at the National Institute of Standards and Technology might have just found a way to recover those numbers and stop criminals in their tracks, however. Their new technique uses electron microscopes to spot damaged crystal patterns in steel, revealing characters even when they've been polished into oblivion. Current recovery approaches (like acid etching or electrolytic polishing) only sometimes work, and frequently provide faint clues at best -- the microscope produces clear evidence that you could use to convict someone in court.
Recommended Reading: sexist video games and origins of forensic science
Recommended Reading highlights the best long-form writing on technology and more in print and on the web. Some weeks, you'll also find short reviews of books that we think are worth your time. We hope you enjoy the read. Is 'Assassin's Creed' Sexist? Is Link a Girl? And More Fun Questions From This Year's E3 by Emily Yoshida, Grantland Pocket!function(d,i){if(!d.getElementById(i)){var j=d.createElement("script");j.id=i;j.src="https://widgets.getpocket.com/v1/j/btn.js?v=1";var w=d.getElementById(i);d.body.appendChild(j);}}(document,"pocket-btn-js"); The sad truth is, if Samus (the heavily armored hero in Metroid) made her debut today, her big reveal would probably be just as shocking today as it was in 1986. While attitudes towards women -- even in the decidedly male-dominated world of gaming -- have matured, putting a female protagonist in a video game is still something of a rarity. (And, if you believe representatives of Ubisoft, something of a technical challenge... but that feels disingenuous.) Emily Yoshida shares what it's like to be a woman at E3, perhaps the most testosterone-drenched tech convention of the year.
How Amiga hackers saved Andy Warhol's digital images
A new documentary from the HIllman Photography Iniative (see the video below) has revealed exactly how those now-famous Andy Warhol Amiga works were extracted from decrepit 3.5-inch floppies. First, researchers had to figure out that the image files were actually saved on the original graphics program diskettes due to quirks in the early Amiga 1000 system. Once the disks were found, Amiga forensics specialists wanted to be the last people to touch them for the sake of their preservation. Since the magnetic material was separating from the substrate, they made sure to read the floppies just once to create a disk image. From there, they used an Amiga emulator to dive into the filesystem, with the "Eureka!" moment coming when they saw filenames like "campbells.pic" and "marilyn1.pic." A quick conversion later, and the images appeared -- as dramatic a moment for the programmers as spotting a Warhold painting at a flea market.
NEC shows 2014-era portable DNA analyzer that could outpace your favorite crime drama
NEC gave us promises of truly on-the-spot forensics when it unveiled its first portable DNA analyzer back in 2007, although the reality hasn't been quite in line with the dream: its current system takes an hour to get a result and won't win any awards for sleekness. From what we're seeing of a next-generation analyzer due in 2014, those expectations are more likely to be met. The new version puts the full DNA extraction, amplification and separation processes on a newer chip that meets NEC's original goal of producing output in 25 minutes -- faster than a short cop drama, if you include the commercial breaks. Few beyond the police will be casually tossing the analyzer around given its 70.5-pound weight and $120,000 price, but a much slicker design at least gives it the profile of a small, rolling suitcase. The upgrade could be vital for identifying suspects and victims in record time; if our only worry is that NEC takes all the mystery out of our favorite TV shows, we'll be more than satisfied.
MIT thaumaturges work to turn any windowed room into a camera obscura
Those interested in criminology, forensics or the basics of voyeurism probably have a decent grasp on what a camera obscura is. For everyone else in the audience, allow us to explain. Used since way before your birth, these chambers are designed with an optical device that projects an image of its surroundings on a screen; you just need a room with a hole in one side, which allows a fine amount of light to pass through. If you've ever watched [insert crime drama here], you've probably seen those magical investigators take a blurred shot of a room wall, zoom it in and somehow draw conclusions about the origins of life. Now, MIT's own Antonio Torralba and William Freeman have developed a method that can "transform the entire setting into a pinhole camera." In other words, any room with a window can be repurposed for forensics. On that note, you should probably consider moving your... operations center to a windowless bunker, STAT.
RIM patent application shines a light on unseen filth, might make forensics mobile
CSI: Waterloo? We're not sure how compelling that spin-off would be (inexplicable popularity of the David Caruso-headlined Miami version aside). So, you'll excuse us for scratching our collective tech head over this recently surfaced patent application filed by RIM in November of 2010. The claims of this bizarre USPTO doc describe an apparatus containing some form of a "display element" attached to a portable electronic device that would generate light on nearby objects, snap photographs and then display results indicating potential contamination. Sounds a lot like those UV wands forensics researchers use on crime scenes, non? Well, whatever it is Heins and co. may have brewing in their Canadian R&D labs, we just pray this isn't BB 10's killer feature. Hit up the source below to peruse the legalese for yourself.
Robot skin captures super detailed 3D surface images
Remember those awesome pin art toys where you could press your hand (or face) into the pins to leaving a lasting impression? Researchers at MIT have taken the idea one (or two) steps further with "GelSight," a hunk of synthetic rubber that creates a detailed computer visualized image of whatever surface you press it against. It works as such: push the reflective side of the gummy against an object (they chose a chicken feather and a $20 bill) and the camera on the other end will capture a 3-D image of the microscopic surface structure. Originally designed as robot "skin," researchers realized the tool could be used in applications from criminal forensics (think bullets and fingerprints) to dermatology. The Coke can-sized machine is so sensitive, it can capture surface subtleties as small as one by two micrometer in surface -- finally solving the mystery of who stole the cookies from the cookie jar. (Hint: we know it was you Velvet Sledgehammer).
Portable device can sniff out anthrax in an hour, won't bring the noise
Got some mysterious white powder sitting on your coffee table? A new, suitcase-sized device can tell you whether you've got dandruff, or anthrax. Developed by researchers at Cornell and the University of Albany, the detector uses a microfluidic chip (pictured on the left) to collect and purify the DNA on a given sample, before conducting a series of polymerase chain reactions -- processes that can quickly identify biological materials. The machine, which has been in the works for seven years, is powerful enough to deliver test results in just one hour (requiring a sample of only 40 microscopic spores), but is slim enough to fit in an airline's overhead luggage bin. Scientists say their creation could also be catered to pick up on other pathogens, including salmonella, and may even pay dividends for crime scene investigators handling forensic evidence. No word yet on when the device could hit the market, but we won't touch an ounce of sugar until it does.
CCTV cameras help solve 'six crimes a day' in London, says Metropolitan Police
Been questioning the value of having omnipresent surveillance cameras tracking your every move? Well, if you're an outlaw, you still won't like them, but for the rest of us law-abiding types, London's Metropolitan Police has a comforting stat to share: almost six crimes a day are being resolved with the help of CCTV footage. It's being used primarily to aid the identification of perps on the run, and the number of suspects identified as a result has gone up to 2,512 this year. There is a bright light for criminals, however, as the Met admits digital recordings aren't kept around as long as VHS ones used to be, meaning that if you slip the dragnet once, you'll probably be alright. So good news for everyone!
Purdue's 'self-calibrating' MEMS could produce the most accurate sensors yet
Micro electromechanical systems, or MEMS, aren't anything new. But Purdue University's Jason Vaughn Clark has ideas that are far grander than those we've seen already. Mr. Clark has purportedly developed a new take on an old spin, with electro micro metrology (EMM) enabling engineers to "account for process variations by determining the precise movement and force that's being applied to, or sensed by, a MEMS device." These self-calibrating machines are the first to do so without any external references, which would allow nanotechnologists, crime forensics researchers and a whole host of others to determine what actually happens at a microscopic level. In theory, the gurus working on this stuff long to improve the accuracy of atomic force microscopes and to eventually create a diminutive AFM-on-a-chip, which -- according to Clark -- could "open the door to the nanoworld to a much larger number of groups or individuals." We're waiting.
Investigate Trauma Team's forensics missions
A few weeks ago, Atlus demonstrated Trauma Team's forensics segments for us in a webcast. The publisher just released a new trailer focusing on that mode, so you can witness the medical crime-solving gameplay for yourself. It's like Phoenix Wright, but more medical-y, and with more revealing clothes. Of course, it wouldn't be Trauma Center without some odd supernatural elements, and in Trauma Team's forensic missions, space virus monsters give way to phone calls from the dead. If only Dr. Naomi Kimishima had the presence of mind to ask the victims who killed them.
Impressions: Trauma Team's adventure game-style forensics mode
Trauma Team's forensics, one of the six medical disciplines represented in the Trauma Center sequel, doesn't just involve examining dead bodies for cause of death. The forensic examiner in this game, Trauma Center's Dr. Naomi Kimishima, takes a more holistic, CSI approach to her job, searching crime scenes, interviewing witnesses, and doing all the work of figuring out the events surrounding the victim's death. What that means for us is that Trauma Team contains an adventure game among its six discrete play styles. And, judging by the case we were walked through in an online presentation by Atlus, it looks like an interesting one!
Investigate a Crime Scene trailer
Having gotten the obligatory joke out of the way in the first post about SouthPeak's Crime Scene, we're now free to look at, you know, the game and stuff. And it certainly delivers on the promise of the title! It's basically a crime scene on the DS for you to explore. You have to comb through whole rooms, collecting fingerprints, footprints and other evidence. You get to tweeze -- and swab. Crime Scene is one of the few M-rated games on DS -- joining an elite club comprising games like Resident Evil: Deadly Silence, the Dementiums, Grand Theft Auto: Chinatown Wars, and, of course, Touch the Dead. With that rating, it may turn out to be a more realistic, serious take on crime than the other cop games on DS. %Gallery-71109%
