When we first heard about researchers using tiny freely floating tools to grab tissue samples deep inside the body, we were scared.
But our fears quickly turned to fascination.
Johns Hopkins engineers are testing out what they call "untethered microgrippers" as a better way to investigate hard-to-reach places. They have launched hundreds of these things, which look like miniature ninja throwing stars, inside the body of animal to retrieve tiny pieces of tissue for biopsies.
This is SCIENCE FRIDAY. I'm Ira Flatow. We're broadcasting today from the Grand Theatre at Salt Lake Community College. And, of course, just up the road from Salt Lake City is the city's namesake, the Great Salt Lake. Parts of it are 10 times saltier than the ocean. But this is no Dead Sea. It's teeming with microbes which can turn the water bubblegum pink.

Once upon a time, giants roamed the planet — many of them in what is now Utah. A panel of paleontology experts describes some of the state's ancient treasures, from massive long-necked sauropods to the Utahraptor, a predator that would put those in Jurassic Park to shame.
The James Webb Space Telescope will succeed Hubble in 2018, boasting modern computers and a mirror with seven times the viewing area. Bob Hellekson, ATK Program Manager for the telescope, discusses the telescope's newly constructed wings, designed to support the telescope's folding mirror, and astrophysicist Stacy Palen talks about what the telescope may reveal about the cosmos.
Smartphones can check e-mail, record videos and even stream NPR. Now NASA has discovered they make pretty decent satellites, too. Three smart phones launched into space this past Sunday are orbiting above us even now, transmitting data and images back to Earth. The PhoneSats, which cost just a few thousand dollars each, could usher in big changes for the satellite industry.
The U.S. military and law enforcement agencies have seen increased public scrutiny on the domestic use of the robotically piloted planes known as drones. Working on the sidelines of this debate, the U.S. Geological Survey has been trying to find a second life for retired military drones in the areas of environmental and wildlife management. Instead of watching the battlefield, these drones are watching birds.
Jeffrey Bronfman, UDV church national vice president; Solar Law, UDV church national president; and Tai Bixby, head pastor of the Santa Fe congregation. Churchgoers participate in a ceremony where hallucinogenic <em>huasca</em> tea is consumed, and some neighbors are trying to block the construction of a UDV temple.
A small church in Santa Fe, N.M., has grown up around a unique sacrament. Twice a month, the congregation meets in a ritualized setting to drink Brazilian huasca tea, which has psychoactive properties said to produce a trance-like state.
The Supreme Court confirmed the UDV church's right to exist in 2006. The church doesn't seek new members and prefers to keep a low profile. It did, however, agree for the first time to open up to a journalist.
When you travel, do you want to drink Bellinis in Venice and yak butter tea in Tibet? Well, so do monkeys.
Monkeys will eat new, different food if they travel to a new place and want to fit in with the locals, according to a new study. But back home, they'll eat what Mama eats, shunning perfectly good food if it doesn't get her approval.
We're going to switch gears now and tell you about a competition that is really about to take off - pun intended. We're talking about the nation's largest rocketry tournament, the Team America Rocketry Challenge.
If you think that making a model rocket is kids' stuff, listen to this: Teams must build a rocket that can fly as close to 800 feet as possible in about 45 seconds. The rockets have to carry two raw eggs into the air and bring them back safely. The top-ranked teams will compete in the national competition on May 11th.
