In 2004, pediatric audiologist Allyson Sisler-Dinwiddie plunged into a world of silence after a car accident damaged her hearing. Under the care of hearing researcher Rene Gifford, she became one of the first test subjects of a new technique to improve cochlear implants, devices that use electrodes to stimulate cells in the inner ear. Since then, Sisler-Dinwiddie and Gifford have worked together to restore other patients' hearing. Watch the pair and their team at Vanderbilt University as they develop a resounding remedy to help people hear again.

Tucked in a shallow valley in northeastern Pennsylvania is a mysterious geologic feature: 16 acres of sandstone boulders. Science Friday took a trip to Hickory Run State Park's "boulder field" and spoke with Megan Taylor, environmental education specialist, about why the rocks collected there.

Although we all know that sneezes and coughs transmit infections, little research had been done to model how they work. To address this knowledge gap, Dr. Lydia Bourouiba and Dr. John Bush of MIT's Applied Mathematics Lab used high speed cameras and fluid mechanics to reveal why we've grossly underestimated the role of gas clouds in these violent expirations.

It's crunch time for the 'balloonatics' at Macy's Parade Studio. The balloons themselves, which are designed and fabricated in a warehouse in New Jersey, are getting their final checkup before the Macy's Thanksgiving Day Parade. John Piper and Jim Artle take us around the studio and spill the secrets of inflation, explain how to calculate whether your balloon will float, and explain why the balloons look better after a little time in the sun. (Broadcast Nov 2011)

The idea of mining Mars, the moon, or an asteroid for its mineral or water resources isn't far-fetched. NASA, the ESA, and several commercial enterprises already have missions in various stages of planning - all to test technologies and probe off-planet terrain for resource extraction. But before you go and land your finely-tuned space drill on an asteroid and suck out the water and carbon, you need to test it out here on earth. And before you do that, you need something to stand in for the rocks and soil of these interplanetary bodies. Using existing data from previous missions, a pinch of geology and chemistry, and and whole lot of jerry-rigged pressure cookers, researchers at Deep Space Industries are cooking up these simulants by the bucket full.

Agave plants, probably best known as the source of tequila, were important as a food crop long before the invention of margaritas. Wendy Hodgson, botanist at the Desert Botanical Garden in Phoenix, says the plants were cultivated as far back as 800 AD in some parts of the Southwest. Trek through the Arizona desert to see where agaves were cultivated centuries ago and what remains of the ancient gardens.

Science Friday salutes a great science teacher. "Office hours are some of my favorite hours of the week," says professor Tom Carlson, a medical doctor, ethnobotanist and instructor of 1700 students annually at the University of California, Berkeley. One of Carlson's former students, SciFri associate senior producer Christopher Intagliata, told us that Carlson's class was the reason he got into science.

Photographer Colin Legg makes time-lapse movies of celestial scenes, from auroras to eclipses. Photographing mostly in remote parts of Australia, where human-made light doesn't compete with starlight, Legg describes some of the challenges of this type of photography -- from babysitting cameras for days and nights on end to running electronics in the backcountry.

For honey bees, making is a new queens is a simple as adding royal jelly, a unique protein rich secretion, to the cell of a growing larvae. This fairly well studied addition causes a cascade of physiological changes in the growing larvae and voila! A queen is born. However, what causes a baby bumblebee (the fuzzier and more weather-hardy cousins to honey bees) to become royalty remains a mystery. They don’t produce royal jelly but they produce a unique barf for their young. Enter entomologist Hollis Woodard and her students at UC Riverside who hope that by understanding how queens are created, they can mitigate on-going extinction crises in bumblebees species. Woodard and company begin by heading up to San Bernardino mountains outside Los Angeles. Here, the researchers collect emerging queens as they buzz around the blooming Manzanita shrubs. These queens are brought back to the lab, where the establish their own (see through) honeypots. Lavished with food by the lab members, the queens lay dozens of larvae which become daughter drones. These drones are then “milked” for their barf which is analyzed for its chemical properties. Future larvae are hand fed the analyzed barf in various quantities and intervals to determine what factors lead to the generation of queen bees.

Big and boisterous, Spotigy and Buri appear to be standard 1-year-old bulls. But a quick glance at their furry heads and closer examination of their genes would reveal that they're unique specimens—hornless Holsteins. The bulls are the result of a gene-editing experiment by Alison Van Eenennaam and colleagues at UC Davis, along with researchers at the biotech company Recombinetics, who aim to develop hornless cattle that might one day replace cows whose horns must be physical removed through expensive and painful methods. Van Eenennaam explains how the technique of "precision breeding" can be a faster and more effective means of de-horning cows compared to traditional breeding methods.

Each year, millions of Americans pay to have their eyeballs poked, prodded, suctioned, sliced and zapped with a laser. In exchange, their vision is corrected. In this video, we go inside an operating room at Acuity Laser Eye and Vision Center in Bethlehem, Pennsylvania to watch Dr. Steven Vale, who has done over 20,000 surgeries, perform lasik eye surgery. See for yourself!

In perhaps the cutest study published in the Proceedings of the National Academy of Sciences, psychologist Marcel Zentner and Tuomas Eerola found that babies will spontaneously boogie when they hear music and other rhythmic sounds. The findings suggest babies are not great dancers, but they smile more when they do hit the beat.

From 2011: Using the Swedish Solar Telescope, a ground-based observatory, Goran Scharmer and colleagues probe the penumbra--that's the stringy structure around the perimeter of the dark part of the sunspot. The images give scientists new insight into how that structure forms.

An elephant shrew is neither an elephant nor a shrew and has a manatee for a close relative. It's more like a mix between a miniature antelope and anteater. Researchers recently discovered a new species of elephant-shrew in Tanzania

The Greater sage-grouse makes its living in sagebrush habitats across the western U.S. and Canada. Every year from late February to May, male sage-grouse perform a striking dance routine each morning at dawn. Jason Robinson, upland game coordinator for the Utah Division of Wildlife Resources, breaks down the dance and describes challenges the birds face.
