Biden Trips, Tumbles on Air Force Stage

President Joe Biden took a face-first tumble on Thursday after tripping over an obstacle on stage at the Air Force Academy in Colorado, but he appeared unhurt -- and joked about it later.

Biden, 80, who had delivered the commencement address to graduates of the military academy, had just shaken hands with a cadet and begun walking back to his seat when he fell, AFP said.

Air Force personnel helped him back up and he did not appear to require further help.

As he rose, Biden pointed to the object that had apparently caught his foot. It resembled a small black sandbag on the stage.

White House Communications Director Ben LaBolt tweeted shortly afterward that "he's fine. There was a sandbag on stage while he was shaking hands."

Returning by Air Force One and Marine One to the White House later, Biden had another spot of bad luck: he bumped his head exiting the door of the helicopter.

He showed no sign of injury as he walked across the South Lawn and quipped to reporters that "I got sandbagged."

Biden is the oldest person ever in the presidency and is seeking a second term in the 2024 election. His official doctor's report this year declared him physically fit and he exercises regularly.

In November 2020, shortly after winning his election against the incumbent Donald Trump, Biden broke his foot while playing with a pet dog.

A new carnivorous caterpillar that wears the remains of its prey has been dubbed the “bone collector.”
The odd insect is only found on the Hawaiian island of Oahu. It creeps along spiderwebs, feeding on trapped insects and decorating its silk case with their body parts, The Associated Press reported.
There are other meat-eating caterpillars that “do lots of crazy things, but this takes the cake,” said study author Dan Rubinoff with the University of Hawaii at Manoa.
Scientists think the case might act as camouflage, allowing the caterpillar to feast on the spider’s ensnared meals without getting caught.
A host of caterpillars native to Hawaii use silk glands to spin protective cases studded with lichen, sand and other materials. This one is the first to use ant heads and fly wings.
“It really is an astonishing type of case,” said Steven Montgomery, an entomology consultant in Hawaii who was not involved with the new study.
Findings were published Thursday in the journal Science. Scientists found just 62 of the carnivorous caterpillars in over 20 years of observing.
Predatory caterpillars are extremely rare and the bone collectors found in Hawaii will even eat each other, researchers said.
The bone collector's origins date back at least 6 million years, making the caterpillars more ancient than the Hawaiian islands themselves. Today, they dwell on an isolated patch of mountain forest alongside invasive species.
“There is really a concern that we need to do better with conservation,” said Rubinoff.
