Your loyal pooch may be bringing a whole world of bacteria into your home — but don't panic. Research suggests that exposure to a wide variety of microbes may be good for us.

When April and Bryan Gionfriddo brought home their newborn son, Kaiba, in October 2011, he seemed like a healthy baby. But one night, when the family was out to dinner, Kaiba stopped being able to breathe and turned blue. Bryan laid Kaiba, just 6 weeks old, on the restaurant table and performed chest compressions on him before he was rushed to the hospital.

Two new species of short-tailed whip scorpions have been found living deep inside the cool, humid caves of northeastern Brazil, a study reports.

Take a look at the western sky just after sunset this week, and you’ll see an amazing sight: three bright planets in close formation.

The lunar crash site from an meteorite strike on the moon is taking center stage in cosmic crime scene investigation and you can see the space rock impact zone online in a free webcast tonight (May 22).

A deadly tornado hit suburban Oklahoma City on Monday. A quick look at some basic facts:

Everyone makes mistakes — even Einstein. The truth is, many of the world's greatest scientists made significant blunders along the path toward genius, which should be comforting news for the rest of us.

By Irene Klotz CAPE CANAVERAL, Florida (Reuters) - An automated telescope monitoring the moon has captured images of an 88-pound (40 kg) rock slamming into the lunar surface, creating a bright flash of light, NASA scientists said on Friday. The explosion on March 17 was the biggest seen since NASA began watching the moon for meteoroid impacts about eight years ago. So far, more than 300 strikes have been recorded. ...

By Tom Brown MIAMI (Reuters) - The U.S. National Weather Service is getting a quantum jump in computing power that will significantly improve its forecasting and storm tracking abilities to better protect the country from severe weather. "This is a game changer," Louis Uccellini, who took over as director of the National Weather Service in February, told Reuters in an interview, calling it "the biggest increase in operational capacity that we've ever had. ...

By Irene Klotz CAPE CANAVERAL, Florida (Reuters) - NASA's first telescope dispatched to hunt for Earth-like planets that may support life elsewhere in the universe has lost use of its positioning system, threatening its mission, officials said on Wednesday. Launched in 2009, the Kepler space telescope revolutionized the study of so-called exoplanets, with discovery of 130 worlds orbiting distant stars and 2,700 potential planets still awaiting confirmation. ...

By Environment Correspondent Alister Doyle OSLO (Reuters) - Ninety-seven percent of scientists say global warming is mainly man-made but a wide public belief that experts are divided is making it harder to gain support for policies to curb climate change, an international study showed on Thursday. The report found an overwhelming view among scientists that human activity, led by the use of fossil fuels, was the main cause of rising temperatures in recent decades. ...

By Sharon Begley NEW YORK (Reuters) - After more than 15 years of failures by scientists around the world and one outright fraud, biologists have finally created human stem cells by the same technique that produced Dolly the cloned sheep in 1996: They transplanted genetic material from an adult cell into an egg whose own DNA had been removed. The result is a harvest of human embryonic stem cells, the seemingly magic cells capable of morphing into any of the 200-plus kinds that make up a person. ...
