  • Study: Warming water means less oxygen for sea life

    Low-oxygen zones where sea life is threatened or cannot survive are growing as the oceans are heated by global warming, a new study warns. Oxygen-depleted zones in the central and eastern equatorial Atlantic and equatorial Pacific oceans appear to have expanded over the last 50 years, researchers report in Friday's edition of the journal Science. Low-oxygen zones in the Gulf of Mexico and other areas also have been studied in recent years, raising concerns about the threat to sea life.

  • CDC: Measles cases highest in 6 years

    Measles outbreaks in several states have led to more than 70 cases so far this year, the worst in six years, health officials said Thursday. Most of the cases have been traced to outbreaks overseas and are mainly in children who were not vaccinated for religious or other reasons, according to the Centers for Disease control and Prevention.

  • Astronomers get closer view of black hole jet

    While we may never know what it looks like inside a black hole, astronomers recently obtained one of the closest views yet. The sighting allowed scientists to confirm theories about how these giant cosmic sinkholes spew out jets of particles travelling at nearly the speed of light.

  • Narwhals more at risk to Arctic warming than polar bears

    The polar bear has become an icon of global warming vulnerability, but a new study found an Arctic mammal that may be even more at risk to climate change: the narwhal. The narwhal, a whale with a long spiral tusk that inspired the myth of the unicorn, edged out the polar bear for the ranking of most potentially vulnerable in a climate change risk analysis of Arctic marine mammals.

  • Moderate quake shakes Mexico

    A moderate earthquake rattled Mexico on Sunday, but no major injuries or damages were reported. The quake had a preliminary magnitude of 5.8 and was centered 96 miles north of Acapulco, the U.S. Geological Center said. Mexico's National Seismological Service released a preliminary magnitude of 5.6.

"Yes, it scared us," said Julio Lara, 38, a parking attendant in downtown Mexico City. "It was strong."

  • Wolves, no more endangered, targeted

    Tony Saunders stalked his prey for 35 miles by snowmobile through western Wyoming's Hoback Basin, finally reaching a clearing where he took out a .270-caliber rifle and shot the wolf twice from 30 yards away. Gray wolves in the Northern Rockies have been taken off the endangered species list and are being hunted freely for the first time since they were placed on that list three decades ago, and nowhere is that hunting easier than Wyoming. Most of the state with the exception of the Yellowstone National Park area has been designated a "predator zone," where wolves can be shot at will.
