Supermarkets have spent decades catering to the needs and wants of baby boomers, and now the millennial generation is disappointed with what they're finding at traditional grocery stores, and are shopping elsewhere in greater numbers.

In fact, a new market research report called Trouble in Aisle 5 reports that millennials buy only 41 percent of their food at traditional grocery stores, compared to the boomers' 50 percent.

We now know that Pluto, the dwarf planet formerly known as a planet, has one more moon orbiting it. Using the Hubble Space telescope, astronomers have discovered Pluto's fifth moon.

NPR's Joe Palca filed this report for our Newscast unit:

"The housing market has turned—at last.

"The U.S. finally has moved beyond attention-grabbing predictions from housing 'experts' that housing is bottoming. The numbers are now convincing.

Finally, there's some good news about Alzheimer's disease.

It turns out that a few lucky people carry a genetic mutation that greatly reduces their risk of getting the disease, an Icelandic team reports in the journal Nature.

The mutation also seems to protect people who don't have Alzheimer's disease from the cognitive decline that typically occurs with age.

Eleven-year-old Woosuk Kim sees his mother only three or four times a year. That's because he's part of what Koreans call a "goose family": a family that migrates in search of English-language schooling.

A goose family, Woosuk explains, means "parents — mom and dad — have to be separate for the kids' education."

Woosuk's father brought him and his little brother to America two years ago to attend Hancock Park Elementary, a public school in Los Angeles. The boys' mother stayed in South Korea to keep working.

With a vote of 244 to 185, the Republican-controlled House of Representatives just voted to repeal the Affordable Care Act, President Obama's signature domestic legislation known colloquially as "Obamacare."

Of course, the vote doesn't matter, because the measure has a very slim chance of being adopted by the Senate.

The AP reports that this is the "33rd time in 18 months that the tea party-infused GOP majority has tried to scrap, defund or scale back the law since grabbing the majority."

Bear in Heaven, the brainchild of Jon Philpot, spent the winter trimming down (from a quartet to a trio) and stocking up, releasing its third album I Love You, It's Cool this spring. To promote the record, Philpot posted it in its entirety on the band's website, but not before slowing the audio down 400,000 times. At its original tempo, Bear in Heaven's music is at once ambient and energized, resonating in synth-driven waves that swell and pulse through an electric sea.
