April showers bring May flowers. But in this case, the blossoms are too small for even a bumblebee to see.
Engineers at Harvard University have figured out a way to make microscopic sculptures of roses, tulips and violets, each smaller than a strand of hair.
To get a sense of just how small these flower sculptures are, grab a penny and flip it on its back. Right in the middle of the Lincoln Memorial, you'll see a faint impression of Abraham Lincoln. These roses would make a perfect corsage for the president's jacket lapel.
Her hair is brown and tied back into a professional-looking ponytail. She wears a blue shirt, tan sweater and delicate gold chain. It's the first time she has met the man sitting across from her, and she looks out at him, her eyes curious.
"So how are you doing today?" she asks cautiously, trying to build rapport.
As the country awaits two important Supreme Court decisions involving state laws on same-sex marriage, a small but consistent body of research suggests that laws that ban gay marriage — or approve it — can affect the mental health of gay, lesbian and bisexual Americans.
Communications barriers have long vexed us, as showcased in the movie "Rush Hour."

CHRIS TUCKER: (As Carter) Do you understand the words that are coming out of my mouth?
LYDEN: Scientists in the 17th century were working hard to understand; mainly, the secrets of the universe but also, each other. With Latin on the decline, they were seeking a whole new way of communicating that would defy barriers and borders - a universal language.
Some residents near a proposed wind farm on Lookout Mountain are getting organized to oppose the project.
The Gadsden Times (http://bit.ly/189DqYI ) reports that about 35 residents met Saturday to share their opinions about the project planned by Pioneer Green Energy of Austin, Texas.
Resident Brandon Balenger said the project shouldn't be so close to people who live at the base of the mountain. Chris Lipscomb said his house is about 1,900 feet from the project, and he expects it to cut his home value in half.
If you're driving down the road someday and you come across a camper with a 50-foot periscope sticking up into the sky, you just might have crossed paths with Ira Leifer. His quirky vehicle is on a serious mission. It's sniffing the air for methane, a gas that contributes to global warming.
Leifer is an atmospheric scientist at the University of California, Santa Barbara. But you'll more often find him off campus, in a garage, next to a string of auto body shops near the airport.

MELISSA BLOCK, HOST:
And I'm Melissa Block. Yesterday, President Obama sent out a tweet drawing attention to a study about climate change. The study found that scientists who say climate change is largely caused by human activities vastly outnumber the skeptics. NPR's Richard Harris has more on the study that caught the White House's attention.
Generations of physicists have claimed that time is an illusion. But not all agree. In his book Time Reborn: From the Crisis in Physics to the Future of the Universe, theoretical physicist Lee Smolin argues that time exists--and he says time is key to understanding the evolution of the universe.
This is SCIENCE FRIDAY, I'm Ira Flatow. This week, scientists at the Oregon Health and Science University, OHSU, announced a breakthrough in cloning of a human embryo. They took adult cells, put the cells into specially prepared human eggs and created genetically identical embryos. It's something lots of stem cell researchers have been trying to do for years without success.
What's on your plate? What do you like to eat? What are you eating for lunch, dinner at this point? As with many things, the answer to that might have a lot to do with what you're accustomed to do and, you know, what part of the world you live in. In some parts of the world, insects can be a delicious part of the diet. Well here not so much.
