Time for a new medical specialty: GLBT

Gay men are svelter than straight guys. Lesbian women are more likely to be overweight.

Northeastern and Harvard researchers this week said they’ve found huge disparities in several measures of health and heart disease risk, between straight and gay populations.

Indeed, the gaps between straight and gay people are so great– lesbian women are 50 percent more likely than straight women to be obese, for example — I believe it is time that medical schools consider training docs to specialize in the primary care of GLBT patients.

More from the study:

• Gay men and women were more likely to be current smokers compared to their heterosexual counterparts.• Lesbian women and bisexuals were more likely to report having multiple risk factors for heart disease.• Sexual minorities as a whole were more likely to report experiencing some form of sexual assault during their lifetime.

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.

Attention unimaginative bloggers: IBM app spits out topics to write about

Every writer could use a muse, sometimes. Photo: Ygor Oliveira/Flickr CC

You might think a roomful of monkeys could generate most of the blog posts you read.

But IBM Research has got it all down to a single program. Called Blog Muse, it generates topics for you to write about, based upon what audiences are asking for.

Blog muse isn’t an artificial brain. Rather than tapping that roomful of monkeys for raw material, however, it crowd-sources requests for stories from the naked apes in your community. (Read the paper about Blog Muse, which is being presented at computer conferences this winter and spring, below.)

IBMers Werner Geyer and Casey Dugan created Blog Muse.

Dugan studied at MIT, under the computer science giant, and Creative Commons founding director, Hal Abelson. She is working IBM’s Beehive Project, which aims to influence social networking behavior.

Plot sickens: Bishop a suspected bomber, too

UAH alleged shooter Amy Bishop may have had a singular  way of settling scores — by the bullet, or the bomb.

The Globe reports today that the nutty professor was suspected, too, of sending pipe bombs to a supervisor at Children’s Hospital.

Many great quotes in this story, such as this one:

“We knew she had a beef with Paul Rosenberg. And we really thought it was a really unbelievable coincidence that he would get those bombs.”

iPhone app beats tickets

A couple of hometown developers driven half-mad by alternate-side-of-the-street parking rules have developed an iPod app to get the jump on those meter maids.

It is really a marvel to watch Brookline’s meter maids fan out across Coolidge Corner at 8 a.m. on weekdays. Strolling down Harvard and Steadman streets, they methodically drop their tickets and move on, faster than you can score a black coffee at Peet’s and rush back to your car.

A new iPhone app will give you a jump on these suspected Cylons, by reminding you where you parked and alerting you to scheduled street sweeping days and snow emergency days.

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.

"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.

Docs to fight stress in Second Life

I learned this while researching this Boston Globe piece (link, excerpt, below): Dr. Joe Kvedar, director of the Center for Connected Health in Boston, says cognitive-behavioral therapy is “the next logical step” for clinical testing in-world. (In-world is where Second Lifers say they are, when they are logged-in.) Kvedar, below, addresses a conference, in-world.panel-shot-3.jpg
MD to fight stress in Second Life – The Boston Globe
In another sign that Second Life is beginning to resemble the first, doctors are stepping into the virtual world to reach patients they might otherwise miss.

A Massachusetts General Hospital neurologist, Dr. Daniel Hoch, wants to learn whether therapy administered in Second Life, the virtual world created by Linden Lab, can have benefits in the world that we share with our spouses, kids, death, and taxes.

In coming months, an instructor from Mass. General will lead 20 to 40 Second Life recruits through guided meditations designed to reduce their stress levels.

Note: They are teaching their subjects the Relaxation Response, which I believe is based on Transcendental Meditation. — mb
