A New York state judge has knocked down New York City's landmark new ban on big, sugary drinks, just one day before it was set to take effect.

Who knew that the flower nectar of citrus plants — including some varieties of grapefruit, lemon and oranges — contains caffeine? As does the nectar of coffee plant flowers.

And when honeybees feed on caffeine-containing nectar, it turns out, the caffeine buzz seems to improve their memories — or their motivations for going back for more.

"It is surprising," says Geraldine Wright at Newcastle University in the the U.K., the lead researcher of a new honeybee study published in the journal Science.

When NPR, the Robert Wood Johnson Foundation and the Harvard School of Public Health asked parents and caregivers in our new poll whether getting a good night's sleep is important, families overwhelmingly told us that sleep is a high priority.

But almost all said that it's difficult to pull off. And studies suggest this is especially true for teenagers.

Alright, an inauguration is never complete without a night of inaugural balls. Both official events were held at the Washington Convention Center.

NPR's Allison Aubrey went to check out the scene and meet the guests who were there. Turns out, when you get a ticket to a ball with the president of the United States, you just get to Washington. Who needs a hotel?

When it comes to supernutritious foods, the blueberry has long had a health halo floating over it.

Going back to Colonial times when Native Americans and English settlers ground up blueberries and added them to porridge, in both dried and fresh forms, there have been hints of health-promoting effects.

If I were rich, I might hire a sous chef. But for now, I'm learning to cheat time. And here's a new way I've stumbled upon to save a minute or two every time I use garlic.

Toss it in the microwave. I put the whole bulb in — 15 to 20 seconds will do the trick. It makes peeling much easier. The cloves practically slide -– or pop — out of their skins, though I won't make any promises about stickiness.

But, since I'm on the science desk, I have to ask, how does it work?

The idea that milk may diminish the potential heart-health benefits of tea has been a topic of some debate. Lots of us can't imagine black tea without a little dairy to cut the bitterness. But, according to this research going back to 2007, we might want to at least consider trying, say, a nice cup of green tea sans sugar or cream.

Beginning next week, McDonald's plans to add calorie counts to its menu boards — both at drive-thrus and restaurant counters. Studies suggest that calorie boards alone don't change consumers' purchasing patterns. But consumers do seem to take note, and public health experts say it's one tangible step to helping consumers make healthier choices.

It may be more important than we thought to tackle obesity in childhood. A new study published in Pediatrics finds that overweight teenagers eat fewer calories than their healthy weight peers.

That's right — they eat less.
