Teen sets off on round-the-world sail

SYDNEY – A 16-year-old Australian steered her bright pink yacht out of Sydney Harbor on Sunday to start her bid to become the youngest person to sail solo and unassisted around the world.

Jessica Watson's plan to make a 23,600-mile (38,000-kilometer) journey through some of the world's most treacherous waters sparked a debate in Australia about whether someone so young should be allowed to try such a potentially dangerous feat.

Watson and her family insist she is an experienced and capable sailor who has studied navigation, electronics and maritime safety procedures. Although she will sail solo and unassisted, she will be in constant contact with her support team via radio, e-mail and a blog.

Komodo Dragon Originated in Australia

livescience.com – Tue Oct 6, 11:46 am ET

Dragons may come from the land Down Under.

Scientists now find that the world's largest living lizard species, the Komodo dragon, most likely evolved in Australia and dispersed westward to its current home in Indonesia.

In the past, researchers had suggested the Komodo dragon (Varanus komodoensis) developed from a smaller ancestor isolated on the Indonesian islands, evolving its large size as a response to lack of competition from other predators or as a specialist hunter of pygmy elephants known as Stegodon.

However, over the past three years, an international team of scientists unearthed numerous fossils from eastern Australia dated from 300,000 years ago to roughly 4 million years ago that they now know belong to the Komodo dragon.

Stress is killing Australia's koalas

By TANALEE SMITH, Associated Press Writer Tanalee Smith, Associated Press Writer – Tue Sep 29, 1:23 pm ET

CUDLEE CREEK, Australia – The koala, Australia's star symbol, is dying of stress.

Koalas live in the rolling hills and flat plains where eucalyptus trees grow, because they need the leaves for both food and water. But as people move in, koalas are finding themselves with fewer trees, researchers say. The stress is bringing out a latent disease that infects 50 to 90 percent of the animals.

"Koalas are in diabolical trouble," says researcher Frank Carrick, who heads the Koala Study Program at the University of Queensland. "Numbers show that even in their stronghold, koala numbers are declining alarmingly."

More New Creatures Discovered Underground In Australia

Down under in Australia, down underground, scientists have found 850 previously unknown species living in subterranean water, caves and micro-caverns.

These insects, crustaceans, spiders and worms are likely only about one-fifth of the number of undiscovered species the researchers think exist underground amid the harsh conditions of the Australian outback. Two species of blind fish and two of blind eels were also uncovered.

"What we've found is that you don't have to go searching in the depths of the ocean to discover new species of invertebrate animals - you just have to look in your own backyard," said researcher Andy Austin, an evolutionary biologist at the University of Adelaide in Australia. [Scientists say only a fraction of the species of plants and animals on the planet have been discovered.]
