A Chinese American teen is vying to become the youngest person to fly solo to all seven continents in a quest that also aims to drum up donations for research into childhood cancer.

Ethan Guo, who turned 19 last month, began his quest in May in Memphis, Tennessee. He made multiple overnight stops and visited seven countries to get to the Swiss city of Geneva on Tuesday, before jetting off toward Heraklion in Greece, The Associated Press reported.

The plan is to cover 50,000 miles (80,000 kilometers) over 100 days with stops in 60 countries. He hopes attention to the journey will drum up donations and raise up to $1 million for cancer research, an ambition born of the Stage-4 blood cancer diagnosis for a cousin of his.

That prompted the tousled-haired teen to reach out to St. Jude Children's Research Hospital based in Memphis.

“We came up with the idea of ... how we can work on this together,” Guo said, "how we can make this world a better place.”

So far, he has raised about $20,000, but he's convinced he will draw more donations.

A press handler for Guo showed The Associated Press an email exchange with an official at Guinness World Records Ltd. about the teen's hope to become the youngest person to fly solo to seven continents. The London-based company did not immediately respond to an email from the AP seeking comment.

Guo started learning to fly at age 13, and four years later had his pilot's license, but insurance companies balked at covering a minor for his adventure, so he had to wait. He has clocked 700 flight hours and flown to all of the 48 contiguous states in the US.

On the tarmac near Geneva airport, Guo said only about one in 10 of the companies he pitched to become sponsors actually came through.

Logos of companies large and small adorn Guo's modified four-seater Cessna 182. Visitors can track his progress on the website flightagainstcancer.com.

Born in Tianjin, China, and currently living in West Palm Beach, Florida, Guo said he wanted to become a pilot to challenge himself. He foresees a career in business and tech, not aviation.
Guo's parents were worried about his project and actively tried to stop him, forcing him to do it on his own with help from volunteers, sponsors and other supporters, he said.
He understands the risks.
“Through my experiences — like an engine failure on the very beginning of the trip ... I was forced to face the fact that I could die at any point of the trip,” he said.
He’s made preparations like stocking the plane with cold-weather gear for Antarctica, a survival kit if he gets stranded in the desert, and an inflatable raft if he lands in an ocean.
“I’ll be lying to tell you if I wasn’t scared,” Guo said. “But every day I reaffirm myself. I say ‘This is what I believe in.' (...) So I’m going to fight on until the very end.”



Fossils Suggest Even Smaller ‘Hobbits’ Roamed an Indonesian Island 700,000 Years Ago

Twenty years ago on an Indonesian island, scientists discovered fossils of an early human species that stood at about 3 1/2 feet (1.07 meters) tall — earning them the nickname “hobbits.”

Now a new study suggests ancestors of the hobbits were even slightly shorter.

“We did not expect that we would find smaller individuals from such an old site,” study co-author Yousuke Kaifu of the University of Tokyo said in an email.

The original hobbit fossils — named by the discoverers after characters in “The Lord of the Rings” — date back to between 60,000 and 100,000 years ago. The new fossils were excavated at a site called Mata Menge, about 45 miles from the cave where the first hobbit remains were uncovered.

In 2016, researchers suspected the earlier relatives could be shorter than the hobbits after studying a jawbone and teeth collected from the new site. Further analysis of a tiny arm bone fragment and teeth suggests the ancestors were a mere 2.4 inches (6 centimeters) shorter and existed 700,000 years ago.

“They’ve convincingly shown that these were very small individuals,” said Dean Falk, an evolutionary anthropologist at Florida State University who was not involved with the research.

The findings were published Tuesday in the journal Nature Communications.

Researchers have debated how the hobbits – named Homo floresiensis after the remote Indonesian island of Flores – evolved to be so small and where they fall in the human evolutionary story. They're thought to be among the last early human species to go extinct.

Scientists don't yet know whether the hobbits shrank from an earlier, taller human species called Homo erectus that lived in the area, or from an even more primitive human predecessor. More research – and fossils – are needed to pin down the hobbits’ place in human evolution, said Matt Tocheri, an anthropologist at Canada's Lakehead University.

“This question remains unanswered and will continue to be a focus of research for some time to come,” Tocheri, who was not involved with the research, said in an email.
