A three-year-old komodo dragon has died at an Indonesian zoo infamous for scores of animal deaths, zoo officials said Saturday.

A zookeeper found the dragon dead in its cage on Saturday morning when he came to feed the giant lizard.

It happens to nearly everyone: A song — let's say Abba's "Waterloo" — is stuck in your head and just won't go away.

Now science has not one but three ways to dig that dreaded earworm out. And none of them are too surprising, as researchers surveyed 18,000 residents of Finland and England and reported their findings in the journal PLOS One.

The Jade Rabbit did not go quietly into that long lunar night.

Instead, China's troubled robotic moon rover — given voice by a government news agency — melodramatically pondered the meaning of its perhaps-fleeting existence, measured its contribution to humanity and, finally, said goodbye.

In Britain, wild swans may be prized for their beauty and protected by the Queen, but the U.S. state of New York has declared war on them, branding them a violent menace.

Draft proposals to kill or resettle the state's 2,200 wild mute swans by 2025 may be supported by some conservationists but have sparked uproar among animal rights activists.

Australia's Great Barrier Reef Marine Park Authority on Friday approved the dumping of up to three million cubic meters of dredge waste in park waters in a move blasted by environmentalists.

The decision follows the government giving the green light to a major coal port expansion for India's Adani Group on the reef coast in December, under some of the strictest-ever environmental conditions.

A controversial French biologist, whose 2012 paper on the alleged dangers of pesticides was withdrawn, has published new claims that the chemicals were many times more toxic than advertised.

Gilles-Eric Seralini's earlier work found that rats exposed to genetically modified maize and the pesticide Roundup developed tumors and other health problems, but his findings were questioned and his paper in the journal Food and Chemical Toxicology finally retracted after his study methods were found lacking.

The stunning and little-understood annual migration of millions of Monarch butterflies to spend the winter in Mexico is in danger of disappearing, experts said Wednesday, after numbers dropped to their lowest level since record-keeping began in 1993.

Their report blamed the displacement of the milkweed the species feeds on by genetically modified crops and urban sprawl in the United States, extreme weather trends and the dramatic reduction of the butterflies' habitat in Mexico due to illegal logging of the trees they depend on for shelter.

The 1-3 percent of the Neanderthal genome that survives in modern humans likely helped early homo sapiens adapt to cold Europe by conferring a thicker skin, researchers said Wednesday.

It may also have transferred a genetically higher risk for diabetes and lupus.

Europe's bat population recovered by more than 40 percent between 1993 and 2011 after decades of decline, according to a survey published by the European Environment Agency (EEA) on Thursday.

In their most comprehensive study yet, surveyors fanned out across nine countries to count numbers at 6,000 sites used for hibernation by 16 of Europe's 45 bat species.

Climate change means more extreme weather and baby penguins are paying the price with their lives, said a pair of long-term studies out Wednesday.

Soaking rainstorms and unusual heat have killed vast numbers of young Magellanic penguins at the bottom tip of South America, said one of the papers published in the journal PLOS ONE.
