Thousands of immigrants have died crossing the southern U.S. border. Many are never identified, leaving their loved ones to speculate about their fate.

For several years now, the city of Waco has been trying to make the historic mammoth site a national monument. The city council decided last night to seek executive action from President Obama to make this resolution a reality. 


For years, some residents of Parker County in North Texas have believed that nearby gas drilling was responsible for high levels of methane in neighborhood water wells. Research published today in the Proceedings of the National Academy of Sciences appears to back that up.

The study looked at water contamination in Texas and Pennsylvania. It suggests that faulty cement jobs on drilling wells could be at fault in North Texas. Cement is poured between the rock wall and the steel tubing of oil and gas wells to block contaminants.

“We think either there isn’t enough cement in this location or more likely there are cracks or imperfections in that cement. That’s what allowed the strong gas to move up through the well and then out into peoples drinking water,” says Robert Jackson, a professor of environmental sciences at Stanford, who co-authored of the study.

It’s been a shaky week in Texas with two small earthquakes rattling the Dallas-Fort Worth area and another slightly more powerful quake detected in South Texas.

On Sunday, the first quake measuring magnitude 2.4 struck near Arlington. It prompted some residents to call 9-1-1 after feeling their houses shake and hearing “explosions,” according to the Fort Worth Star Telegram.

Earthquakes are often accompanied by loud “booms,” something that has become a source of anxiety in newly quake-prone parts of the state.

We reported on Monday that a meteor, thought possibly to be a chunk of an Earth-passing asteroid, was the cause of a 40-foot crater outside the international airport in the Nicaraguan capital.

But astronomers and NASA scientists are now casting doubt on that possibility. The biggest mystery is that no one so far has reported seeing a flash of light in the sky that would be expected to accompany such a meteor strike.

Space is a dangerous place. That message resonated again on Monday, when the Russian Federal Space Agency — Roscosmos — announced that a team of experimental geckos tasked with copulating while in orbit did not survive their journey.

"All geckos, unfortunately, died," the space agency said in a terse statement.

Roscosmos is launching an investigation into the exact circumstances surrounding the geckos' deaths, but the mission seemed star-crossed from the start.

Given that science is believed to be about certainty, betting on a scientific idea sounds like an oxymoron.

Yet scientists bet on ideas all the time, even if mostly for jest. Of course, this only makes sense before we have any data pointing toward the correctness of the disputed hypothesis.

Back in the 1990s, historical societies, museums and symphonies across the country began transferring all kinds of information onto what was thought to be a very durable medium: the compact disc.

Now, preservationists are worried that a lot of key information stored on CDs — from sound recordings to public records — is going to disappear. Some of those little silver discs are degrading, and researchers at the Library of Congress are trying to figure out why.

Four Guys and a Boat Tackle a Texas-Sized Water Problem

Jul 30, 2014

As the sun rose on Lake Arrowhead late last week, four guys on a motorboat armed with 5,739 pounds of white powder set out to tackle one of Texas' most vexing water problems — evaporation from surface reservoirs. Last year, evaporation cost the state 2 trillion gallons of water, and it has been eliminating as much as 40 million gallons of water a day from drought-stricken Wichita Falls' supply this summer.

The four men, who work for a company called Flexible Solutions, were applying WaterSavr to Lake Arrowhead. The company claims that its product will save the city hundreds of millions of gallons of water by preventing evaporation. At a cost of $400,000 for the product and labor, the city is hoping the experiment, the first of its size in the nation, will work. And the rest of parched Texas is watching. But there are plenty of skeptics.

Earlier this year, the earth hit a frightening milestone: carbon dioxide in the atmosphere reached its highest level since humans have inhabited the earth. The last time there was this much carbon on the planet was nearly a million years ago.

As the heat-trapping gas proliferates, the world warms, and the climate effects domino: droughts intensify, floods increase, ice melts and seas rise. The question now isn't whether human activity is changing the global climate; the question is what to do about it.

Scientists: Asteroid Caught Dinosaurs At A Bad Time

A team of geologists and paleontologists has agreed on an issue that you might have not realized was still in question: an asteroid, and the fallout from its impact, killed the dinosaurs. Some dinosaur experts were holding out on blaming the asteroid, saying that dinosaurs were already on their way out. The scientists say they're getting a better understanding of the "tempo" of dinosaur extinction.


Forty-five years ago today, in arguably the greatest technological feat of the 20th Century, two Americans stepped off the ladder of their small landing craft and walked on the surface of the moon.

The first of them, Neil Armstrong, 38, of Wapakoneta, Ohio, pronounced his accomplishment "one small step for [a] man; one giant leap for mankind." The second, 39-year-old New Jersey native Edwin "Buzz" Aldrin, Jr., described what he saw as "magnificent desolation."

Why We Can't Multitask (But Think We Can)

Jul 14, 2014

Do you take pride in your ability to divide your focus and energy into more than one task at a time? Do you think you’re a good multitasker?

Chances are, you’re probably not.

We sat down with two experts – the Two Guys, Dr. Art Markman and Dr. Robert Duke  to take a closer look at the topic of multitasking. Their take offers a perspective into some of the unique issues associated with multitasking.

At long last, the ultimate in that "distressed look" for jeans.

To help support the Kamine Zoo in Hitachi City, Japan, the Mineko Club of volunteer zoo boosters is holding an auction of three pairs of one-of-a-kind bluejeans designed by lions and tigers and, yes, bears too.

According to an English-language translation on the group's website, "Zoo Jeans are the only jeans on earth designed by dangerous animals."

Every year, more than half of the honeybee hives in the United States are taken to California to pollinate the state's almond crop.

Biologist Laurence Packer says this illustrates both our dependence on honeybees to pollinate many plants people rely on for food and the devastating decline in the domestic honeybee population in recent years.
