Next Steve Jobs or Mini Albert Einstein?

Political Punch

The White House invited some of the smartest kids in the country to come show off their inventions the other day. The White House's East Room — normally a place for prime time press conferences and State Dinners was transformed into a science fair. ABC's Senior White House correspondent Jake Tapper took a tour of the displays and shows us what these little geniuses have come up with. Maybe there's a future Steve Jobs or Albert Einstein among them?

Take Taylor Wilson who says when he was 14 years old, he developed a nuclear fusion reactor. Now only 17 he's developed a tool that could be a big help for counter-terrorism -- detecting Uranium-235, Weapons Grade Plutonium and Highly Enriched Uranium — using a not-so-rare ingredient: water.

Or 14 year old Benjamin Hylak, who designed an interactive robot to allow him to Skype with his grandmother, and also find her pills and pour her a glass of water. Amazing!

And you know the old saying necessity is the mother of invention? Well, 12-year-old Ma'Kese Wesley and 11-year-old Isis Thompson heard about the deadly bacteria outbreaks on cantaloupe melons last year and came up with a high tech lunch box that zaps fruits and vegetables using UV light and makes them safe to eat.

These kids are all pretty incredible. Enough to make a White House reporter feel a little intimidated.

Test driver has close call with deer

In this exclusive video to Yahoo News, professional formula driver Ken Gushi has an extremely close call with a wild deer who runs across the road directly into Gushi's path.

Gushi was test driving the forthcoming Toyota Scion FR-S in northern California's Mt. Diablo State Park when the near-mishap took place. Director Simon Needham captures the whole thing in HD, including Gushi's reaction.

"On my very first run of the day today we were up in the canyons driving and I come across this left hand turn over a crest and down onto a straight," Gushi says in the video. "I'm trying to mind my own business driving and trying to navigate these unknown roads when all of a sudden I see this black figure just prancing toward the road. At that moment, I just knew, 'Oh, s--- something's wrong.'"

"I got on the brakes and I see this deer coming down the mountain, getting as close as two or three feet, and again just prancing, minding his own business."

Thankfully, neither Gushi nor the deer were hurt.

According to National Highway Traffic Safety Administration statistics, deer are responsible for or involved in around 1 million collisions with automobiles each year, killing 200 Americans, causing more than 10,000 injuries and $1 billion in vehicle damage.
