Friday's deadline for President Obama to issue a sequestration order is neither the beginning nor the end of this year's budget battles in Washington. Here are five key moments to watch over the next seven months, and what's at stake in each:

Robert Lustig wants to convince the world that sugar is making us very sick. And lately he's turned to an unconventional field – econometrics – to do it.

Lustig rounded up statisticians and epidemiologists to look at the relationship between food and diabetes risk. The paper, published this week in the journal PLoS One, found that the more sugar on the market in 175 countries, the higher the country's diabetes rate.

The governor of the Bank of Greece says the recession has cut Greece’s economic output by 20.1 percent between 2008 and 2012. Earlier this week George Provopoulos says the country is “clearly improving,” but Greece’s economy would remain stuck in recession in 2013.

Alison Johnston is a comparative political scientist at Oregon State University, and studies economics and labor markets in the European Union. She says Greece will only leave the eurozone voluntarily.

“Are countries going to get kicked out of the euro?” Johnston asks. “Whenever I'm asked this question, I like to ask people, 'Well how likely is it that you think that a state like Massachusetts could kick a state like California out of the dollar because California might be borrowing from the U.S. government?'”

A wave of violence has rocked Bangladesh after a special war crimes tribunal Thursday imposed the death penalty on an Islamist leader for his role in the country's 1971 war of independence from Pakistan.

Demonstrators for and against the convicted leader clashed with security forces, leaving dozens of people dead, including police.

The violence demonstrates the deep sensitivities that remain over the war of independence that played out more than 40 years ago.

"Washington sure isn't making it easy" for the American people and the American economy, President Obama told reporters late Friday morning as he and other lawmakers failed to reach a deal to avert $85 billion worth of automatic "sequester" spending cuts due to start at the end of the day.

This is TELL ME MORE from NPR News. I'm Michel Martin. Coming up, you've heard the pundits and the politicians give their take on the new S-word - sequestration. We'll ask the Barber Shop guys for their perspective on this later in the program. But first we want to talk about another big topic in Washington this week. That is the challenge to the landmark Voting Rights Act of 1965. That's before the Supreme Court, specifically section five of the act.

This fall, health insurers in a few states will be seeing stars.

Not the celestial kind, but stars that reflect their scores on quality measures picked to help consumers make informed decisions when buying health coverage.

Kim Dotcom, founder of the file-sharing website Megaupload, says he will take his fight against extradition to the United States to New Zealand's highest court, after an appeals court ruled in the U.S. government's favor Friday.

At issue is the amount of evidence Dotcom's defense team is entitled to see at the extradition hearing. An appeals court overruled a lower court's decision that the U.S. government had to provide more than a summary of its case against the Internet entrepreneur.

Far above the Earth's surface, two doughnuts of radiation surround the planet, charged particles zipping around in stable belts - that's the shape of them - and they were discovered in 1958 by James Van Allen and now bear his name. They are the Van Allen Belts.

Robert Langer is sort of a modern-day Thomas Edison. He holds over 800 patents. He's launched two dozen startups making an eclectic variety of stuff from tumor-zapping nanoparticles to biosensors and blood tests, synthetic spinal cords, even anti-frizz hair products, all of this originating from the same lab. And recently, President Obama awarded him the National Medal of Technology and Innovation. He's already won the National Medal of Science, after all.
