Pollution typically declines during a recession. Not this time. Despite a global economic slump, worldwide carbon dioxide pollution jumped 2 percent last year, most of the increase coming from China, according to a study published online Tuesday.
Chimps, our nearest relative, don't talk. We do. Now scientists have pinpointed a mutation in a gene that might help explain the difference. The mutation seems to have helped humans develop speech and language. It's probably not the only gene involved, but researchers found the gene looks and acts differently in chimps and humans, according to a study published online Wednesday by the journal Nature.
Have you heard that the world is now cooling instead of warming? You may have seen some news reports on the Internet or heard about it from a provocative new book. Only one problem: It's not true, according to an analysis of the numbers done by several independent statisticians for The Associated Press.
NASA needs to make a major detour on its grand plans to return astronauts to the moon, a special independent panel told the White House Thursday.
Call it a star party with real star power.
NASA's great lunar fireworks finale fizzled. After gearing up for the space agency's much-hyped mission to hurl two spacecraft into the moon, the public turned away from the sky Friday anything but dazzled. Photos and video of the impact showed little more than a fuzzy white flash.
Because of a lethal combination of geology and geography, the people of American Samoa didn't stand much of a chance. Almost every condition that triggers bad tsunamis was in place this time, generating waves that raced toward the island territory at speeds approaching 530 mph, or as fast as a 747 jumbo jet. And there was almost nothing to slow the water down.
The moon isn't the dry dull place it seems. Traces of water lurk in the dirt unseen.
New satellite information shows that ice sheets in Greenland and western Antarctica continue to shrink faster than scientists thought and in some places are already in runaway melt mode.
President Barack Obama is calling on the world to end massive government subsidies that encourage the use of fossil fuels blamed for global warming.
Astronomers have finally found a place outside our solar system where there's a firm place to stand — if only it weren't so broiling hot.
It's the birth defect people don't talk about. A baby is born not completely male or female. The old term was hermaphrodite, then intersex. Now it's called "disorders of sexual development." Sometimes the person with the problem doesn't even know it and finds out in an all too public way.
Joint U.S.-Canada exploration of the Arctic sea floor discovered an unusual underwater mountain and evidence that could boost the two countries' claims that their boundaries extend farther north. For the past two months ships from the countries have ventured north in icy areas of the Arctic where almost no surface ships have been, in an effort to find out how far the continental shelf extends.
A White House panel of independent space experts says NASA's return-to-the-moon plan just won't fly.
Our nearest major galactic neighbor is a cosmic cannibal. And it's heading this way eventually. Astronomers have long suspected Andromeda of being a space predator, consuming dwarf galaxies that wander too close. Now, cosmic detectives are doing a massive search of the neighborhood and have found proof of Andromeda's sordid past: They've spotted leftovers in Andromeda's wake.
NASA will test the powerful first stage of its new Ares moon rocket Thursday, a milestone in a program that has already spent $7 billion for a rocket that astronauts may never use.
Astronomers have found what appears to be a gigantic suicidal planet.
Steve Kramer spent an hour and a half swimming in the ocean Sunday — in Maine. The water temperature was 72 degrees — more like Ocean City, Md., this time of year. And Ocean City's water temp hit 88 degrees this week, toasty even by Miami Beach standards.
NASA is charged with spotting most of the asteroids that pose a threat to Earth but doesn't have the money to complete the job, a federal report says.
"Cash for clunkers" could have the same effect on global warming pollution as shutting down the entire country — every automobile, every factory, every power plant — for an hour per year. That could rise to three hours if the program is extended by Congress and remains as popular as it is now.
Two teams of Chinese scientists have made a major advance in mice in the development of a new kind of stem cell that doesn't involve destroying embryos.
Scientists believe they have found a "missing link" in the evolution of the virus that causes AIDS. It bridges the gap between the infection that does no harm to most monkeys and the one that kills millions of people. That link is a virus that is killing chimpanzees in the wild at a disturbingly high rate, according to a study in Thursday's journal Nature.
The day Apollo 11 landed on the moon 40 years ago, it inspired Eddie Lee McGhee to name his newborn daughter after the lunar lander. But he didn't name her Eagle. He named her Module.
NASA's new boss said Tuesday he will be "incredibly disappointed" if people aren't on Mars — or venturing somewhere beyond it — in his lifetime.
When Neil Armstrong first spoke from the moon, he said one thing and people on Earth heard another. What the world heard was grammatically flubbed: "That's one small step for man; one giant leap for mankind." Armstrong insists he said: "That's one small step for 'a' man." It's just that people just didn't hear it.
