Superstorm Sandy sparked a lot of interest in rising sea levels when it swept across the Northeast last month and flooded parts of the coast. Over the next century, more water — and higher sea levels — could come from melting ice in Greenland and Antarctica. How much has been unclear.
But now scientists have developed a much clearer view of how quickly that ice has been melting over the past two decades. And that will help researchers forecast the rate of sea-level rise in the years to come.
The taste of Mock's tomatoes starts with the seed. He uses only organic varieties, including cherry and several heirloom varieties.

There's a greenhouse boom around the country, thanks in part to the "buy local" movement. Paul Mock grows tomatoes, herbs and other veggies year-round in his Berkeley Springs, W.Va., greenhouse and sells to groceries and restaurants in the Mid-Atlantic.

"This is unprecedented, the level of opportunity," says Mock, whose business is booming.
It may sound like an oxymoron: a delicious local, winter tomato — especially if you happen to live in a cold climate.
But increasingly, farmers from West Virginia to Maine and through the Midwest are going indoors to produce tomatoes and other veggies in demand during the winter months. "There's a huge increase in greenhouse operations," Harry Klee of the University of Florida tells us.
Before Secretary of State Hilary Rodham Clinton passes the reins to her successor, she's got a few loose ends to tie up. One of them is mapping out the U.S.'s continuing efforts to combat AIDS around the world.
So today she unveiled a "blueprint" for what she called an "AIDS-free generation."
Now Clinton isn't talking about ending the HIV pandemic altogether. Rather, she hopes to prevent most new infections from occurring in the first place and to stop HIV-positive people from developing AIDS.
Mercury is not the first planet to come to mind if you were searching for ice in the solar system. After all, the surface temperature across most of the planet is hot enough to melt lead.
But at the poles on Mercury it's a different story. Almost no sun reaches the poles, and as a result, temperatures can drop to less than -100 degrees Fahrenheit. Now, three papers in the journal Science suggest there really is ice at the bottom of craters near the poles on Mercury.
It's that time of year again — the leaves have fallen, the dark comes early, the air brings with it a certain chill — and I've been piling up books on my reading table, books I've culled from the offerings of the past few months, which because of their essential lyric beauty and power stand as special gifts for you and yours.

Mitt Romney refused to mix religion with politics in this year's presidential campaign, but that didn't repress people's curiosity about Mormonism. His candidacy brought the homegrown faith into the spotlight.
Patrick Mason, a professor and chairman of the Mormon Studies program at Claremont Graduate University, says attention paid to his faith has been twofold. On one hand, it's been good for attracting new converts. On the other hand, it's turned Mormonism into something of a cultural punch line.
Details are still emerging in the wake of a factory fire that killed more than 100 textile workers outside the Bangladesh capital of Dhaka. Melissa Block speaks with Reuters' South Asia bureau chief, John Chalmers, about the latest from Bangladesh, where protests have raged for three days.
