Sans titre

Police were seeking a “devious defecator": the person responsible for leaving piles of poop in the aisles of a grocery store outside Atlanta. So to help out, the company that operates the store, Atlas Logistics Group Retail Services, asked employee suspects to take a voluntary cheek-swab genetic test.

Two employees who worked in the warehouse didn’t want to take the test because they felt humiliated and feared where their genetic information would end up, but they did so because they felt their jobs were on the line, as Buzzfeed reports. When the results came back, it turned out that neither employee was behind the vandalism. In May 2013, seven months after the test, the employees sued Atlas for genetic discrimination.

TAMPA — Fingerprints are so 20th-century. For special operations forces conducting midnight raids in places like Pakistan or Syria, DNA is becoming the gold standard.

Representatives from the U.S. Special Operations Command revealed that they were testing two rapidDNA readers in forward locations. The operators feed in a DNA sample, and the reader compares it against a database that matches DNA to identities. The machines weigh some 60 pounds, so they aren’t small. And they aren’t cheap: each costs about $250,000. But they cangive a result in 90 minutes, a process that used to take weeks.

The devices are the RapidHIT 200 from IntegenX, a California-based company, and the DNAscan from Massachusetts-basedNetBIO.

What will they use them for? Verifying the identity of targets, either before raids or after the fact.

Ultimately, he wants a rugged, battery-powered DNA reader the size of a cellphone, which will allow special operations fighters to “collect DNA right there on the site.” It should connect to a database to allow verification on location as well.

Such a device might be available for field-testing around 2019 or 2020. “It’s a ways out” said Benji Hutchinson, senior director of federal business for MophoTrust, a company that markets the IntegenX. It would “require a major lift,” he said.

Shrinking the technology is just one obstacle to a hand-heldDNA matching system. Perhaps more important is growing the database of DNA samples to match against.

Enter Genecoin, a newcomer in the Bitcoin space that seeks to fulfill an unlikely spot in our Blockchain future: the encoding and storage of who we are. Despite its name, Genecoin is not a crypto currency or a counterparty asset. Genecoin is the name of a nascent company run by a group of anonymous bitcoiners based in a undisclosed location in the United States’ northeast coast. The members of Genecoin are offering a simple proposition to the Bitcoin universe: to populate the Bitcoin Blockchain with the sequenced DNA of its customers.

Amongst the many technical challenges that Genecoin is openly addressing is just how to store this DNA data using Bitcoin. Given that your typical human’s unencrypted DNA takes up approximately 750 MiB of data, storage of this data in full, on the Blockchain, would be significantly cost prohibitive. However, Genecoin is quick to point out that much of this data is redundant between humans, and that this size can be drastically reduced by merely encoding the ‘differences’ amongst a single human’s DNA from those of a reference model. Such an encoding would require off-chain data be used for reference, and Genecoin is exploring various ways of referencing this data in a decentralized capacity. In addition to the considerations surrounding space efficiency, Genecoin is actively exploring mechanisms to encrypt the storage of one’s DNA on the Blockchain as well. After all, just because one wants their data to persist forever, doesn’t mean they want everyone privy to it. Options for latter decryption would include time-lock, and oracle-based decryption schemes.

Intestinal gases have been linked to colon cancer, irritable bowel syndrome and inflammatory bowel disease, and could potentially be used as key biomarkers for assessing overall health.

The new technology -- developed by researchers from RMIT University and Monash University in Melbourne, Australia -- measures the concentration of selected intestinal gases through a swallowable capsule with a built-in gas sensor, microprocessor and wireless high-frequency transmitter.

Lead investigator, RMIT's Professor Kourosh Kalantar-zadeh, said current non-invasive methods of measuring intestinal gas -- such as breath testing -- were unreliable.

Project Cyborg is a cloud-based meta-platform of design tools for programming matter across domains and scales. Project Cyborg provides elastic cloud-based computation in a web-based CAD shell for services such as modeling, simulation and multi-objective design optimization. Researchers, developers, students and citizen scientists can use these tools to advance their own projects and, if they choose, share their work with others and even use Project Cyborg as a marketplace. Cyborg allows individuals or groups to create specialized design platforms specific for their domains, whatever their domains happen to be, from nanoparticle design to tissue engineering, to self-assembling human-scale manufacturing.

As part of Baylor's research, Watson analyzed more than 70,000 scientific articles related to p53, a protein that has been linked to many cancers. Automated analysis carried out by Watson helped Baylor biologists and data scientists identify six proteins that modify p53 and that should be targeted for new research. Most important, the discovery was made in a matter of weeks, according to IBM.

"In the life sciences industry at large, researchers typically come across one of these target proteins per year," said IBM Watson VP John Gordon. "Baylor working with Watson found six targets, and the first two that they've taken into wet labs have been validated, so they're outpacing the industry."

In a new study published in the journal Science today, Burke has announced the specs of a chemistry's own version of the 3D printer—a machine that can systematically synthesize thousands of different molecules (including the ratanhine molecular family) from a handful of starting chemicals. Such a machine could not only make ratanhine step-by-step, but also could custom-create a dozen other closely-related chemicals—some never even synthesized before by humans. That could allow scientists to test the medicinal properties of a whole molecular family.
