Did you know that most mammals, from a house cat to an elephant, take roughly the same amount of time to urinate? Researchers at Georgia Tech collected data, streamed via online video and in real life, and discovered that a combination of physiology and gravity enable this feat of fluid dynamics.

By studying tiger and cat tongues, Alexis Noel of Georgia Institute of Technology has discovered some surprising uses for their infamously raspy licking apparatuses. Noel research has demonstrated that not only do their tongues tenderize meat, but the conical and scoop-like form of their papillae are optimized for depositing allergen infused saliva baths. So basically every time you pet your cat you are just rubbing your hand over their evenly-distributed saliva.

Although some were given a ton of catnip.

What can't 3D printers do? We've all heard news stories about 3D-printed food and medical prostheses—even cars and entire houses. But how does additive manufacturing, as it's also known, really work? And how can an at-home hobbyist get started? Ira teams up with Makerbot's Bre Pettis to present the ultimate beginner's guide to 3D printing.

By shrinking an entire museum into a 6 foot tall modular design, MICRO hopes that these tiny exhibits can go in all sorts of public areas, like shopping malls, waiting rooms, airports, and parks where they can integrate science and learning into people's day-to-day lives.

Brian Haus watches as the still air stirs into over 150 mph winds. The flat turquoise water suddenly churns a series of endless crashing waves of white frothy foam. Thankfully, Haus does not have to actually weather these powerful storms. Instead, he gets a close view from a safe distance at the Surge Structure Atmosphere Interaction Facility (or SUSTAIN Laboratory, for short). With a flip of a switch and a large diesel generator, the lab can concoct hurricanes on command in a box—a very large box stretching 75 feet long and 6.5 feet high—mimicking some of the most intense hurricanes that have ever been observed. By brewing these contained storms, Haus and his team can study the complex interactions between the air and the surface of the sea under extreme conditions, and use the information to improve intensity forecasting.

Lightning -- one of the great unsolved mysteries.

A new study in Science investigates the wisdom of crowds... well, schools. Andrew Berdahl, graduate student at Princeton University, explains that Golden shiner minnows prefer shady habitat. And he and his co-authors found that large groups of fish are better at tracking shady habitats than smaller groups or individuals--a demonstration of collective sensing.How do fish pool their senses? The researchers filmed fish and digitized their movement to try to answer the question.

In 2011, comet Lovejoy traveled through the sun's corona and lived to tell the tale. But its tail was the most telling. Reporting in the journal Science, Cooper Downs, an astrophysicist at Predictive Science Inc. in San Diego, Calif., says that the wiggly path of the comet's tail helps explain the sun's magnetic field.

The Rockaways, a Queens, N.Y. neighborhood, is still recovering from Sandy. Debris from fires lingers on the streets, and buildings torn apart by the storm are crumbling on the beach. But at least for those with restored heat and power (7,000 customers in the area are still without power), there is yet another worry: mold. Peter Corless, a community organizer in the Rockaways, gives us a tour of the neighborhood, while Joan Bennett, a mycologist whose house molded after Katrina flooding, describes the species of fungi she found in her own home after that hurricane and in New Jersey homes post-Sandy.

Why do your fingers get pruney after a swim? Only a handful of researchers, including Einar Wilder-Smith, Mark Changizi, and Tom Smulders, have looked into the phenomenon. Publishing in Biology Letters, Smulders lends a hand to the hypothesis, set forth by Changizi and colleagues, that finger wrinkles improve our grip of wet objects.

As a choreographer who often collaborates with dancers with disabilities, Merry Lynn Morris has long thought that traditional manual and power wheelchair designs were constraining. Her work in integrative dance, along with her experience growing up with a father who relied on a wheelchair, inspired her to invent a power wheelchair designed for artistic expression. Equipped with omnidirectional movement, a rotating seat, and a hands-free control, the chair enables dancers to explore new movement techniques, and may one day provide greater mobility in everyday life, too.

Up and down the West coast of the U.S., bees are leaving their hives, flying around at night and then suddenly dropping dead. Learn all about this parasitic horror that quietly zombifies these insects and how you can become a real-life zombee hunter.

Biology graduate student Tom McDonagh is taking shadow puppetry to the next level. One of his latest productions is based on the (true) story of an American doctor and French inventor who took to the skies in a hydrogen balloon and made the first trip -- by air -- across the English Channel. McDonagh, whose Ph.D. project at Rockefeller University has centered on building a microscope, is also experimenting with shadow puppet production -- from laser cut puppets to 3D shadows. McDonagh and puppeteers Jo Jo Hristova, Arlee Chadwick and Emma Wiseman will be performing several of his pieces at Puppet Festival rEvolution on August 6th, 2013 in Swarthmore, PA.

In her new book, Bones Books and Bell Jars, physician and photographer Andrea Baldeck documents the collection of medical texts, instruments, and specimens at Philadelphia's Mütter Museum.

Bacteria and viruses hitch a ride inside droplets of all kinds—sneezes, raindrops, toilet splatter. By reviewing footage of different types of drops, applied mathematician Lydia Bourouiba records and measures where they disperse in order to better understand how diseases spread. Watch how Bourouiba designs tests—some inescapably humorous and awkward—to study infectious disease transmission.

Ice can be hard to get a handle on, literally and figuratively. It can be cloudy or clear, as hard as concrete or as soft as a snowflake. Ice experts Erland Schulson, head of the Ice Research Lab at Dartmouth College, and Shintaro Okamoto, founder of Okamoto Studio in Queens, New York, have staked their livelihoods on the slippery material. We asked them what fascinates them about frozen water. (Originally published Jan 27, 2012)

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.

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.

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.
