Nearly 1 in 20 US adults over 50 have fake knees
CHICAGO (AP) — New research shows that nearly 1 in 20 Americans older than age 50 are living with artificial knees. It's the first such estimate and amounts to about 4.5 million people.
Mexican experts excited to find ancient home ruins
MEXICO CITY (AP) — The ruins aren't particularly impressive, just some stone and clay footings for houses that probably supported walls of wood or clay wattle. And it's that very ordinariness that has experts excited. The remnants being uncovered in the hills east of Mexico City at a spot known as Amecameca are from an ancient neighborhood — a home to regular folks.
Researchers probe 200-year-old shipwreck off RI
WESTERLY, R.I. (AP) — For two centuries it rested a mile from shore, shrouded by a treacherous reef from the pleasure boaters and beachgoers who haunt New England's southern coast. Now, researchers from the U.S. Navy are hoping to confirm what the men who discovered the wreck believe: that the sunken ship off the coast of Rhode Island is the USS Revenge, commanded by Oliver Hazard Perry and lost on a stormy January day in 1811.
Life in Antarctic lake? It's everywhere else
WASHINGTON (AP) — If scientists find microbes in a frigid lake two miles beneath the thick ice of Antarctica, it will illustrate once again that somehow life finds a way to survive in the strangest and harshest places. And it will offer hope that life exists beyond Earth.
La Nina going away, but too late for Texas drought
WASHINGTON (AP) — Federal weather forecasters say the La Nina weather phenomenon that contributed to the southwestern U.S. drought is winding down. The National Weather Service's Climate Prediction Center says La Nina is showing signs that it will be over by summer. Center deputy director Mike Halpert said that's too late for the U.S. southwest because the rainy season will be over by that time. The effects of La Nina, a cooling of the central Pacific, are generally weaker in summer.
Judge tosses case seeking rights for orcas
SAN DIEGO (AP) — An effort to free whales from SeaWorld by claiming they were enslaved made a splash in the news but flopped in court Wednesday. A federal judge in San Diego dismissed an unprecedented lawsuit seeking to grant constitutional protection against slavery to a group of orcas that perform at SeaWorld parks, saying the 13th amendment applies only to humans.
In scientific coup, Russians reach Antarctic lake
MOSCOW (AP) — Opening a scientific frontier miles under the Antarctic ice, Russian experts drilled down and finally reached the surface of a gigantic freshwater lake, an achievement the mission chief likened to placing a man on the moon. Lake Vostok could hold living organisms that have been locked in icy darkness for some 20 million years, as well as clues to the search for life elsewhere in the solar system.
Unplanned 9/11 analysis links noise, whale stress
BOSTON (AP) — An ocean experiment that was accidentally conducted amid the shipping silence after Sept. 11 has shown the first link between underwater noise and stress in whales, researchers reported Wednesday. The analysis indicated that a drop in a stress-related hormone found in the right whales was tied to a dip in ocean noise that followed a near-standstill in ship traffic, due to security concerns following the attacks.
Romanian accused of hacking NASA-JPL computers
LOS ANGELES (AP) — A federal grand jury has indicted a Romanian citizen on charges he hacked into 25 climate-research computers at NASA's Jet Propulsion Laboratory in Pasadena. Tuesday's indictment charges Robert Butyka, 25, with one count of unauthorized impairment of a protected computer, according to the U.S. attorney's office in Los Angeles.
New Obama plan to help math, science teacher prep
WASHINGTON (AP) — President Barack Obama called on Tuesday for millions of dollars in new funding to improve math and science education, an effort he said would be crucial to the nation's long-term success. Obama said his upcoming budget proposal, set to be released next week, would include a request for $80 million from Congress for a new Education Department competition to support math and science teacher preparation programs. Obama made a similar request to Congress last year but the measure didn't pass.
