ANCHORAGE, Alaska (AP) -- A lack of summer sea ice is changing the behavior of Pacific walruses, but they don't know what the effect will be, federal scientists said.

Researchers from the U.S. Geological Survey and Russia tagged 251 walruses in the Chukchi Sea off Alaska's northern coast and tracked their movements from 2008 to 2011. The results were released at a news conference Wednesday in Anchorage.

The study shows walruses are arriving earlier than normal at northern feeding grounds in the summer, according to a news release. When sea ice melted completely, the walruses hauled out on land and foraged for food closer to shore.

Scientists said they don't yet understand the impact of the new behavior, but noted possible higher mortality rates for younger walruses from being trampled.

    The Port Authority of New York and New Jersey is holding its monthly board meeting, two days after it heard from a panel on what it needs to do to improve its accountability and efficiency and restore public trust.
    The Port Authority of New York and New Jersey could rescind a $1-a-year lease for a park-and-ride lot near the Lincoln Tunnel. The agency's chief of real estate and development told a committee Wednesday that it should change a deal made in 2012. Published reports have alleged that former Port Authority chairman David Samson voted to approve the lease even though his law firm did business with New Jersey Transit, which operates the park-and-ride lot.

    A tiny new spy device aims to automatically transcribe and Tweet overheard conversations. It's called Conversnitch.  Brian House and Kyle McDonald are behind the eavesdropping device.  They say it bridges the gap between (presumed) private physical space and public space online.
