NASA has captured the effects of the powerful cyclone that
struck the Myanmar
coast on Saturday, May 3, using an imaging instrument onboard its Terra satellite. The instrument, called the
moderate-resolution imaging spectroradiometer (MODIS), measures the reflective
solar radiation and emitted thermal radiation from the earth's surface and
atmosphere. Atmospheric scientists are currently using the instrument to study
the behavior of clouds and aerosols in our atmosphere so that they can, for
example, pinpoint the locations of active fires and track the paths of
pollutants.
The instrument scans broad swaths of the earth--about 2,300
kilometers at a time--and is able to image the entire earth in one day. Because
it is observing the earth all the time, MODIS is able to capture events that
only happen occasionally, like Cyclone Nargis.

MODIS captured images of the Myanmar coast before and after Cyclone
Nargis struck. The image on the left is the coastline on April 15, and the
image on the right was taken May 5, after the cyclone hit the Irrawaddy delta
and plowed across the country and through the main city of Rangoon. At landfall, winds were
approximately 130 miles per hour, with gusts of 150 to 160 miles per hour,
accompanied by a 12-foot wave. In the images, the water is blue or nearly
black, vegetation is bright green, bare ground is tan, and clouds are white or
light blue.
U.S.
diplomats in Burma
are estimating that the death toll may reach nearly 100,000, but official
reports from the Burmese junta are announcing 22,980 deaths, 42,119 missing,
and 1,383 injured.

Oil money is being enlisted to build a city that will use no oil and produce no carbon emissions.
Monday, May 05, 2008
By Kevin Bullis
Last week, construction began on a huge renewable-energy and urban-planning experiment, and it will be funded by $120-a-barrel oil at an anticipated cost of $22 billion over about eight years. The Masdar Initiative, launched in 2006, is an ambitious project to build a city near Abu Dhabi in the United Arab Emirates. It will house 50,000 people but will produce zero net carbon dioxide emissions and zero waste. Construction just began on the solar power plant that will power the city's construction, and later the city itself. And the first building to go up will be part of the new Masdar Institute of Science and Technology (MIST), a school put together largely with the help of MIT that will be devoted to developing technologies for environmentally sustainable cities.
One of the best things about the project--which I'll write about more in the coming days--is that it provides a much needed way to test ideas for renewable energy and efficiency at a large scale. The hope is that the technology tested here can be applied throughout the world.
But while the project will no doubt provide valuable insights, its location and the circumstances of its construction will limit its applicability. While the Abu Dhabi government won't be providing all of the $22 billion--it's calling on private investment with the hope that the project will be profitable--not every country can count on windfall profits to fund similar projects. What's more, the solutions developed for use in a hot, dry, sunny climate won't necessarily apply to places like, say, New England. Indeed, Gerard Evenden, a senior partner at Foster + Partners, the firm hired to plan the city, says it's essential that cities and buildings be custom-built with the location in mind to maximize efficiency.
Finally, what's to be done with cities that already exist? Many of the approaches to be taken at Masdar--such as controlling the orientation and length of the city streets and the height and construction materials of buildings--won't work with places like New York and Mexico City. This morning at a symposium dedicated to the collaboration between MIT and Masdar, Ernest Moniz, the director of the MIT Energy Initiative, said that a more challenging task is finding ways to retrofit existing systems.

Innovators at 2008 Ideastream discuss the future of research.
Wednesday, April 30, 2008
By Kristina Grifantini
At yesterday's Ideastream symposium, sponsored by MIT's Deshpande Center, researchers mingled with venture
capitalists and investors. One panel featured big names in innovation
discussing issues in funding and the necessity of cross-disciplinary studies.
The new Koch Institute was designed particularly for
cross-disciplinary research, said director Tyler Jacks. It brings together key
researchers in nanotechnology, biology, and infotechnology.
Ernest J. Moniz, director of the MIT Energy Initiative, emphasized
that communication and collaboration are important not just across research
fields, but also across nontechnical areas. "To have those technologies
actually penetrate the market requires interface with management, social
sciences, [and other fields]," he said. This is why integrating investors,
startups, and venture capitalists with researchers is crucial, he added.
"The tonic for the struggle to achieve cross-disciplinary success
is tapping into the young people," said Frank Moss, director of MIT's Media Lab.
He remarked that the Koch Institute's plan of designing for physical proximity
across disciplinary studies is what the Media Institute has strived for, with a
minimal number of walls--and glass ones, at that. Such interdisciplinary focus
has led the Bank of America to fund an upcoming Media Lab project looking at
effective computing, economics, and media, said Moss. Big companies rarely fund
basic research, he noted, but he believes that it's an early indicator of
things to come: "I think over the next few years, we'll see the industry waking
up and seeing [that] basic research is disappearing."
For a portion of the panel, Moniz and Jacks argued
good-naturedly about funding difficulties. Jacks stated that energy research
has an easier time getting funding, while Moniz countered that cancer--something
that everyone is afraid of getting--would be more of a primary target for
funding than energy issues are. "There's no more reliable enemy than death,"
quipped Moniz.
Research team led by MIT professor.

An international team of researchers has identified the contaminant
in a blood thinner called heparin that is thought to be responsible for the
deaths of dozens of Americans.
The contaminant, known as
oversulfated chondroitin sulfate (OSCS), could not be picked up using
traditional tests, as its structure is very similar to that of heparin. The
researchers found that OSCS causes two critical problems: low blood pressure
and anaphylactic reactions. Their findings were published in the New England Journal of Medicine last
week.
From the NEJM:
In January 2008, health authorities
in the United States
beganreceiving reports of clusters of acute hypersensitivity
reactionsin patients undergoing dialysis that had been occurring
sinceNovember 2007. Symptoms included hypotension, facial swelling,tachycardia, urticaria, and nausea. Although initial investigationsfocused
on dialysis equipment, an investigation by the Centersfor Disease
Control and Prevention identified the receipt ofheparin sodium for
injection (1000 U per milliliter, in 10-mland 30-ml multidose
vials), manufactured by Baxter Healthcare,as a common feature of
the cases.1
This finding led Baxter Healthcareto recall, on January 17, 2008,
nine lots of heparin sodiumfor injection. As of April 13, 2008,
there were 81 reports ofdeath that involved at least one sign or
symptom of an allergicreaction or hypotension in patients receiving
heparin sinceJanuary 1, 2007.
Ram Sasisekharan, a professor of biological engineering
at MIT and the lead researcher on the project, says that the key to the team's
approach was that it looked at heparin and the contaminant at a molecular
level. Strong teamwork, he notes, was also important to the project. "A number
of academic and industrial labs worked with me in close collaboration with the
FDA. It was only through cooperation that we were able to accomplish this task
of identifying the contaminant and assessing its biological activity in such a
rapid fashion."
The unique language of LOLCats at ROFLCon.
Friday, April 25, 2008
By Kristina Grifantini
Friday, April 25, was the first of the two-day ROFLCon, an event featuring the people behind current memes of pop Internet culture. The conference, organized by Harvard students and taking place at MIT, was a high-energy crowd of mostly college-age attendees touting signature red ROFLCon lunch boxes.
A panel this afternoon looked at the current popularity of LOLCats, a website that lets users post cat photos paired with clever, referential captions written in a unique baby-talk-cum-text-messaging language. The language is supposed to represent how a cat would talk if it could (with poor grammar and misspellings). LOLSpeak has evolved since the website took off last year, with phrases such as "Facebook ur doin it wrong," "I can has cheezburger?" and the familiar "kthxbai!!!" becoming commonplace. The website was recently featured in Time magazine.
It's the first language that started out written, then became spoken, and it has attracted inquiring linguists, according to Ben Huh, CEO of the LOLCats website.
"It's an expression of the Internet through the actual construction of language," adds Martin Grondin of the spinoff LOLCats Bible.
Some of the phrasing becomes downright cryptic, especially for newcomers (a snarling ferret in a pot captioned "kreme uf angree suop" is "crème of angry soup"), but members of the LOLCats team, of which there are eight, are "fluent."
Panelists included those who did other spinoffs, including LOLTrek, the now-defunct LOLSecretz, and LOLCode. When asked about the future of LOLSpeak and Internet dialects, the panelists seemed to agree that words would get "dumber and shorter." Huh envisions Internet language becoming entirely referential and "all meta"; it would look like a secret language to those on the outside. To the newcomer on LOLCats, it might seem as though it's already here.
It could be a boon to genomics research and personal genomics companies.

After a tortuous 13-year journey, the Genetic Non-Discrimination Act (GINA) has finally passed. The bill will prevent discrimination from employers or insurance companies based on an individual's genetic makeup. Proponents, including genomics researchers and patient advocacy groups, say that the bill removes a major obstacle in the advance of personalized medicine.
According to the Associated Press (via the New York Times):
The bill, described by Sen. Edward Kennedy as ''the first major new civil rights bill of the new century,'' would bar health insurance companies from using genetic information to set premiums or determine enrollment eligibility. Similarly, employers could not use genetic information in hiring, firing or promotion decisions. ''For the first time we act to prevent discrimination before it has taken firm hold and that's why this legislation is unique and groundbreaking,'' said Sen. Olympia Snowe, R-Maine, who sponsored the Senate bill with Sens. Kennedy, D-Mass., and Mike Enzi, R-Wyo. There are more than 1,100 genetic tests available today, she said, but these are ''absolutely useless'' if fear of discrimination discourages people from taking tests or participating in clinical trials.
Surveys have shown that genetic discrimination has been a major concern for the American public, especially when it comes to health insurance. In addition, scientists have reported that some people were afraid to participate in clinical trials that included genetic testing for this reason. (I faced this concern myself when writing a piece for Technology Review that involved taking a genetic test for diabetes risk.)
The bill was first introduced in 1995, before the completion of the human genome and when only a few genetic tests were available. It passed in the Senate twice, but was most recently held up by Senator Tom Coburn, who expressed concerns over lawsuits.
From the New York Times:
One of Senator Coburn's main concerns was that the bill might subject employers to civil rights lawsuits stemming from disputes over medical coverage. And employers that also finance their own health insurance, he said, might be sued twice. "We would have created a trial lawyers' bonanza," he said.
Lawmakers made small changes to the bill that assuaged these concerns.
From GenomeWeb Daily News:
"We believe the final draft of GINA should provide clarity to the health insurance industry, maintain the integrity of the underwriting process, and ensure accurate premium assessments," the senators stated in the letter. Now, the lawmakers have agreed to a key compromise that would salve Coburn's concerns by adding language to create a "firewall" between the parts of the bill dealing with insurers and employers, an adjustment Coburn and the White House said was needed to protect them from some lawsuits, a source on Capitol Hill told GWDN today. The agreement included other "minor" changes having to do with phrasing, according to the source, who asked to remain anonymous.
The approval is also a likely boon to personal genomics companies, such as Navigenics and 23andMe, which provide direct-to-consumer genetic testing assessing individuals' risk for disease.
