The government shutdown is likely to mean an early death for thousands of mice used in research on diseases such as diabetes, cancer and Alzheimer's.
Federal research centers including the National Institutes of Health will have to kill some mice to avoid overcrowding, researchers say. Others will die because it is impossible to maintain certain lines of genetically altered mice without constant monitoring by scientists. And most federal scientists have been banned from their own labs since Oct. 1.

The two paintings are unmistakably by Vincent Van Gogh. Both show a street scene in the south of France, dominated by sturdy trees with limbs thrust upwards. Both show the same trees and the same houses and pedestrians — almost.
The Road Menders and The Large Plane Trees (Road Menders at Saint-Remy) were painted by Van Gogh in May 1889. They're so alike that they are sometimes called "copies." In fact, they're different: strikingly different in color, subtly different in detail.
We all feel the biological master clock, ticking deep within our brains, that tells us when to sleep and when to wake.
Well, it turns out that our skin cells have a circadian rhythm of their own. Researchers have found that depending on the time of day, our skin's stem cells busy themselves with different types of tasks.
I'm Michel Martin and this is TELL ME MORE from NPR News. We've talked before on this program about why Latinos in the U.S. are more likely to tweet and use other social media than other Americans. Today, we're going to hear from a Latino tech leader who wants to boost the Latino presence in the science and business of technology. We'll talk about that in just a few minutes.
The Nobel Prize in Chemistry was awarded jointly to Martin Karplus, Michael Levitt and Arieh Warshel Wednesday. Karplus, Levitt and Warshel won the prize for laying the foundation for computer models that help researchers understand and predict chemical processes like the purification of exhaust fumes or photosynthesis in green leaves.

Browsing farmers markets this fall, you may find some new apple varieties mixed in with the Granny Smiths, McIntoshes and Fujis. Susan Brown, head of the apple breeding program at Cornell University, estimates that there have been 130 new apples released around the world in the past six years.
This summer, she contributed two more to that tally: the SnapDragon and the Ruby Frost.
