The last big ice age ended about 11,000 years ago, and not a moment too soon — it made a lot more of the world livable, at least for humans.
But exactly what caused the big thaw isn't clear, and new research suggests that a wobble in the Earth kicked off a complicated process that changed the whole planet.
Ice tells the history of the Earth's climate: Air bubbles in ice reveal what the atmosphere was like and what the temperature was. And scientists can read this ice, even if it's been buried for thousands of years.
Six-term Republican Sen. Richard Lugar of Indiana is facing his first primary challenge since winning the job in the 1970s. The race is attracting big money from outside groups and superPACs, and is seen as a test of the strength of the Tea Party movement versus the power of incumbency.
Two of America's best-known companies, Coca-Cola and PepsiCo, have dropped their memberships in the American Legislative Exchange Council, a low-profile conservative organization behind the national proliferation of "stand your ground" gun laws.
If there's one building in Jerusalem that represents the city's tangle of religions, this is it. The ground floor is a Jewish holy site said to house the tomb of the biblical King David. The second floor is the Cenacle, a Christian holy site, the room believed to be the site of Jesus' Last Supper. On the roof, there's an old minaret from when this place was marked a Muslim holy site.
One building, three religions, decades of property disputes. And the fight isn't over.
April 6 marks the 20th anniversary of the start of the Bosnian war and the siege of Sarajevo. It was the longest siege of a capital city in modern history, and produced the worst atrocities in Europe since World War II.
Over three-and-a-half years of war, 100,000 people were killed, and half of Bosnia's population of 4.4 million — made up of a plurality of Muslims — fled their homes.
Think of the most technologically innovative companies of the past 50 years, such as Intel, Apple, Google, Facebook and Twitter. Each company has a Silicon Valley address — and each one got backing from venture capitalists. Over the past decade, more than 35 percent of the nation's venture capital has gone to Silicon Valley startups.
High-tech and venture capital go hand and hand in the valley where technology and venture capital grew up together.
A final report from Los Angeles coroner is shedding some light on Whitney Houston's last hours.
According to the report, the pop super star complained of a sore throat and an assistant suggested she take a bath. By the time the assistant got back to the room after running an errand, she found Houston lying face down on in the tub "in approximately 13-inches of water," People Magazine reports.
What's plentiful in upstate New York? Cows and prison inmates, to name a few things.
Reformists in the two communities don't make natural allies, but organizer Lauren Melodia is trying to do just that.
"I was living in this prison town, and at the same time, the dairy industry was in a lot of turmoil," Melodia tells The Salt. "We thought this [dairy] might be the perfect ally in trying to build a different economy in upstate New York, and shift some of the economic dependency away from the prison system."
Much of the Republican political establishment, many GOP voters and political analysts were telling Rick Santorum that the time had come for him to end his quest for his party's presidential nomination even before Tuesday when he failed to win any of three primaries.
Those calls had only increased by Wednesday as Santorum fell further behind Romney in the delegate count.
Though Robert Glasper Experiment is a fairly new entity, Glasper himself has been experimenting in genre mash-ups for his entire musical career. First and foremost a jazz pianist, Glasper grew to love hip-hop and began to incorporate it into his music. He's played in a jazz trio and toured the world playing at jazz festivals, but recently, he's become renowned for his ability to mix unlikely elements into something startlingly original — even if he's covering the work of another artist.
The "Taxi of Tomorrow" has arrived in New York City. On Tuesday night, officials unveiled the Nissan-designed cab that, over the next 10 years, will gradually replace the country's largest taxi fleet. It's the first New York taxi to be designed for the job since the city's iconic Checker cab.
For Nissan's designers, the process of putting the new cab together involved months of riding in taxis and talking to cab owners, drivers and passengers about what they did and didn't like.
The brains of people who grow up speaking two languages are wired differently, and those differences protect them from dementia as they age.
That's the news from two studies out this month from a scientist in Canada who has spent decades trying to figure out whether being bilingual is bad or good. "I've been doing this for 25 years," Ellen Bialystok, a distinguished research professor of psychology at York University in Toronto, tells Shots. "Suddenly people are interested. I figure it's because everybody's scared about dementia."
Former Child Star Fatigue. Many of us have suffered it, given the drug problems, the meltdowns, the awful nude photos.
But then there's Fred Savage, who starred in the ABC show The Wonder Years from 1988 through 1993. Now he's a successful, slightly offbeat 35-five-year-old television producer and director. He works on wicked, slightly warped comedies including Party Down, It's Always Sunny In Philadelphia and as of today, Best Friends Forever. His first network sitcom premieres tonight on NBC.
Locavores, a word with you. Local food may be gaining traction in all kinds of ways, but a report out today from the Institute of Medicine serves as a stark reminder of just how globalized our food system truly is.
