Hunt for Earhart's plane back on
<p></p><p> A new search for the wreckage of Amelia Earhart's plane will launch in 2014, according to an organization that has already launched several expeditions to the Pacific island of Nikumaroro.</p><p> Earhart, a famed aviator, vanished in 1937 along with her navigator Fred Noonan. The two were attempting a flight around the world, and were last seen in Lae, New Guinea. Ever since, theories have circulated that Earhart and Noonan did not die in a crash, but survived for at least a little while after an emergency landing on an uninhabited island.</p><p>[Full Story: <a href="http://www.livescience.com/40415-search-amelia-earhart-plane.html" target="_blank">

Early man all one species?
<p></p><p> The earliest, now-extinct human lineages, once thought to be multiple species, may actually have been one species, researchers now controversially suggest.</p><p> Modern humans, <i>Homo sapiens</i>, are the only living member of the human lineage, <i>Homo</i>, which is thought to have arisen in Africa about 2 million years ago at the beginning of the ice age, also referred to as the Pleistocene Epoch. Many extinct human species were thought to once roam the Earth, such as <i>Homo habilis</i>, suspected to be among the first stone-tool makers; the relatively larger-brained <i>Homo rudolfensis</i>; the relatively slender <i>Homo ergaster</i>; and <i>Homo erectus</i>, the first to regularly keep tools it made.</p><p>[Full Story: <a href="http://www.livescience.com/40505-earliest-humans-one-species.html" target="_blank">

Oreos not as addictive as cocaine
<p></p><p> Oreos as addictive as cocaine? A new study purports to draw a link, but don't check into a treatment center for your Double Stuf addiction just yet.</p><p> Following a Connecticut College press release on an undergraduate student research project, a number of headlines have blared warnings such as "Oreos May Be As Addictive As Cocaine" (TIME) and "College study finds Oreo cookies are as addictive as drugs" (Fox News). The research behind the headlines is not quite so certain, however.</p><p>[Full Story: <a href="http://www.livescience.com/40488-oreos-addictive-cocaine.html" target="_blank">

King Herod's tomb not his
<p></p><p> Herod the Great, the king of Judea who ruled not long before the time of Jesus, seems to have eluded historians once again.</p><p> In 2007 archaeologists announced they had found the great king's tomb, a surprisingly modest mausoleum that was part of the Herodium, a massive complex built by Herod on a cone-shaped hill in the desert outside Jerusalem.</p><p>[Full Story: <a href="http://www.livescience.com/40443-herods-tomb-not-his-tomb.html" target="_blank">

Has geneticist solved Yeti mystery?
<p></p><p>A geneticist believes he may have begun to solve the riddle of one of most enduring myths in all of cryptozoology: the yeti, or Abominable Snowman, of the Himalayas.</p><p> The mystery has swirled through the snows of the mountainous region for centuries, since Alexander the Great searched for a yeti on his eastward march across the Indus Valley. In the 1950s, even respected mountaineers such as Sir Edmund Hillary claimed to have seen footprints of the legendary beast, which reportedly walks upright and is covered with hair.</p><p>[Full Story: <a href="http://www.livescience.com/40502-yeti-genetics-abominable-snowman-polar-bear.html" target="_blank">

Bats use leaves as hearing aids
<p></p><p> Bats in Costa Rica have evolved a neat trick to help them hear their roost-mates flying above: They use leaves to funnel sound in a natural version of an old-timey ear horn.</p><p> The Spix's disc-winged bat (<i>Thyroptera tricolor</i>), named for suction-cuplike discs on its wings and feet, is found in South America. Unlike other cave-dwelling bat species, disc-winged bats roost each day in the unfurling leaves of plants outside of caves. These leaves form a tube shape as they go from folded-up to flat, meaning the bats can roost only for a day before having to find another leaf in the proper shape.</p><p>[Full Story: <a href="http://www.livescience.com/40429-speak-up-costa-rican-bats-use-leaves-as-hearing-aids.html" target="_blank">

Blood-engorged fossil mosquito found
<p></p><p> About 46 million years ago, a mosquito sunk its proboscis into some animal, perhaps a bird or a mammal, and filled up on a meal of blood. Then its luck turned for the worse, as it fell into a lake and sunk to the bottom.</p><p> Normally this wouldn't be newsworthy, and nobody would likely know or care about a long-dead insect in what is now northwest Montana. But somehow, the mosquito didn't immediately decompose — a fortuitous turn of events for modern-day scientists — and became fossilized over the course of many years, said Dale Greenwalt, a researcher at the National Museum of Natural History in Washington, D.C. Greenwalt discovered the mosquito fossil after it was given to the museum as a gift, and he immediately realized the specimen's rarity.</p><p>[Full Story: <a href="http://www.livescience.com/40402-fossil-mosquito-blood-meal.html" target="_blank">
