Tattoo will advertise your genetic flaws

MIT materials experts suggest that an ink made from carbon nanotubes can be injected into diabetics, to monitor their blood glucose levels. Patients can then check their tats for any changes.

Diabetics say this beats pricking their fingers throughout the day. But the tat — which might be partially covered by wristwatch with a UV scanner on the back of it — will also mean wearing your condition on, or near, your shirtsleeve.

The technology behind the MIT sensor, described in a December 2009 issue of ACS Nano, is fundamentally different from existing sensors, says Strano. The sensor is based on carbon nanotubes wrapped in a polymer that is sensitive to glucose concentrations. When this sensor encounters glucose, the nanotubes fluoresce, which can be detected by shining near-infrared light on them. Measuring the amount of fluorescence reveals the concentration of glucose.

The researchers plan to create an “ink” of these nanoparticles suspended in a saline solution that could be injected under the skin like a tattoo. The “tattoo” would last for a specified length of time, probably six months, before needing to be refreshed.

EM field, behind right ear, suspends morality

Morally impaired? Photo: Eddie Van 3000/Flickr CC

This new finding, from MIT, should cause scientists to more closely examine the risks to human health posed by mobile phones and other wireless, personal technologies. — M.B.

MIT neuroscientists believe they have isolated the brain region — just behind the right ear — where moral judgements take place.

And they can suspend someone’s ability to judge right from wrong, simply by generating a magnetic field near the same spot where many of us hold our cellular phones and wireless, Bluetooth, headsets.

The researchers’ findings, announced today:

“In both experiments, the researchers found that when the right TPJ (right temporo-parietal junction) was disrupted, subjects were more likely to judge failed attempts to harm as morally permissible.”

The technique used by the MIT scientists, transcranial magnetic stimulation (TMS), has been described as one that creates “virtual lesions” on the brain.

And although TMS’s long term effects on health are not well understood (similar amounts of electromagnetic radiation have been linked to increased cancer risk), the treatment is becoming increasingly popular for everything from tinnitus to depression.

The US military also hopes to use TMS to keep soldiers fighting, without the need to stop for sleep.

Google to reroute cyclists through cities

Even cyclists, many of whom see themselves as the Apache of their city’s roadways, will soon be taking orders from Google.

A blogger at MIT’s Center for Future Media asks,

“Does this spell the end for DIY cycle mapping? Will having a major commercial bike map provider decrease people’s motivation to contribute their own routes or use potentially clunkier interfaces? Can we learn something here about the relationship between crowd-sourced, DIY public services and corporate takeovers?”

And I thought the whole point of cycling was doing your own thing, with the added thrill of risking head injury.

MIT lab helps designers reimagine video games – The Boston Globe

Lab might do for video games, what USC did for film:

GAMBIT’s researchers, a collaboration of artists, historians, writing instructors, and educators, are mostly interested in breaking away from gaming conventions: the princess who needs rescuing, the shady merchant with the weapon you must get to survive the next chapter, the mushroom power-up.

They are also focused on teaching courses with heady titles like “Making Deep Games’’ and publishing papers such as “Bioshock: A Critical Historical Perspective.’’

“Everything done in the lab is based on some sort of research interest,’’ said Eitan Glinert, who was GAMBIT’s first graduate student, in 2007.

Mars in a month: now doable

Well, make that a month, a week, and a weekend, thanks to a plasma rocket developed by this MIT physicist and former astronaut:

A journey from Earth to Mars could soon take just 39 days, cutting current travel time nearly six times, a rocket scientist who has the ear of the US space agency NASA has said.

MIT's birthday present to Darwin: A tidied-up legacy

darwinHere’s an interesting take on Darwin’s legacy: Darwin was the Black Man’s best friend, according to the organizers of an upcoming symposium (excerpt and link from the conference website, below).

Darwin’s racial views were complex. (He was an abolitionist who seemed to believe blacks were inferior to whites.) And his theories have been very effective in the hands of eugenicists and racists.

The organizers of the MIT symposium, celebrating Darwin’s 200th birthday, blame the impacts of Darwin’s theories on misinterpretations of his work. They also advise President Obama to “follow Darwin’s lead (to unite Man into a single, global, civilization).”

A snippet from the symposium organizers’ web page:

The pseudo-scientific arguments that human “races” are separately evolved continues to rear its head, despite both fossil and genetic evidence establishing that all modern humans had their origin in Africa, before migrating and dispersing through Europe, Asian and the Pacific Islands. Modern genomics reveals clearly that all human groups share a common gene pool. Natural selection certainly continues to operate in human populations, but the invention of language has meant that many of the key features selected for in human populations are transmitted through culture and not through genes. Certainly this is true for the leaps that led to the expansion of humans across the Earth – domestication of plants and animals, irrigation, tool and weapons development, food storage and processing, textiles and clothing, sanitation, long range transportation and communication technologies. But biological determinism still lives, promoting pseudo-scientific claims that the variations that exist in the genomes and physiology of humans, represents profound differences between groups, rather than the normal range of variation found in large populations.

Dance vids include secret "signs"

Jane McGonigal, a social networking marketeer who talks a lot about alternate realities, addictive games, positive psychology and (gods help us) “experience grenades” has come up with a very strange new game. In this video, the tech media darling dons an “Eyes Wide Shut”-type mask, and dances for the webcam, flashing messages to other participants in the game.

(1) Davis Square becomes home to the Hub’s first (if not widely publicized) “pot café,” where people can light up and munch out, and drink coffee. Odds: 50-to-1

(3) Attendance at MassCann’s 2009 Freedom Rally (Boston Common, Sept. 19)  tops 100,000. Odds: 4-to-1

(3) A hipster doofus at the Freedom Rally moans as cops write him a $100 ticket for possession. The cops rough the kid up a bit, and YouTube video-makers are there. Odds: 3-to-1

(4) The U.S. Drug Enforcement Administration raids  a Mexican weed smuggling operation in Eastern Massachusetts. Odds: 10-to-1

Terrorists raid labs for chem-bio-weapons

British intelligence forces are growing their list of terror suspects to include graduate and postgraduate students.

U.S. officials in September nabbed a MIT graduate, Aafia Siddiqui, in Afghanistan, after she took to the wind.

The security services, MI5 and MI6, have intercepted up to 100 potential terrorists posing as postgraduate students who they believe tried accessing laboratories to gain the materials and expertise needed to create chemical, biological, radiological and nuclear weapons, the government has confirmed.

"BioBeer" coming to MIT FrankenFest

Talk about a “eureka” moment in the making: Rice University students are working on a beer packed with resveratrol, the latest miracle antioxidant for health-conscious pill-poppers.

Beer contains antioxidants. But it lacks the very best stuff:

Resveratrol, abundant in red grape products, is known to make fat, old mice, mighty again.

No one knows the effects massive doses of the compound might have on humans, however.

The Rice researchers, who will present their research at an MIT biotech confab in November, say it will be a few years before anyone should be drinking their amped-up brew.

My prediction: a mad young scientist will swill some of the stuff “before its time,” with surprising consequences.–mb

Rice’s “BioBeer” will be entered in the International Genetically Engineered Machine (iGEM) competition Nov. 8-9 in Cambridge, Mass. It’s the world’s largest synthetic biology competition, a contest where teams use a standard toolkit of DNA building blocks — think genetic LEGO blocks — to create living organisms that do odd things.
