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.

This map shows methane measurements Ira Leifer took as he drove in his RV around the Los Angeles basin. Notice the pronounced spike in levels of methane around the La Brea Tar Pits in the center of the image. Geological faults here allow "natural" methane to escape. The redder the color, the more methane was detected.

Leifer stands atop his roving chemistry lab. He and his team took 6,600 methane readings on the cross-country drive from Florida to California.
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.
From NPR News, this is ALL THINGS CONSIDERED. I'm Audie Cornish.
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.
In Brilliant Blunders: From Darwin to Einstein, astrophysicist Mario Livio explores the colossal errors committed by scientific greats, from chemist Linus Pauling's botched model of DNA, to Charles Darwin's failure to understand genetics--the very mechanism of natural selection.
