Have you ever noticed that it's easier to walk without spilling a foamy beer versus walking around with regular cup of coffee? Have you ever wondered why? To solve this everyday physics phenomenon, a team of fluid mechanics researchers at Princeton University's Complex Fluids Lab investigate the anti-sloshing abilities of foam.

Carve first, scoop later--that's just one of the tips from Maniac Pumpkin Carvers Marc and Chris. Based in Brooklyn, these professional illustrators switch to the medium of pumpkin during October. They carve hundreds of pumpkins each fall, which go for a few hundred bucks and rarely end up on stoops. They gave us some tips for how to bring our pumpkins to the next level this Halloween.

Photographer Roman Vishniac is perhaps best-known for documenting Jewish communities in Eastern Europe before World War II, but he also was a science buff. In the 1950s-1970s, with funding from the Educational Testing Service, the National Science Foundation and others, he made educational science films, featuring footage he shot through his microscope. Vishniac was a pioneer of cinemicroscopy (as he called it). The craft has changed with digital photography, says Dutch photographer Wim van Egmond, who has won numerous awards for his photomicrographs. van Egmond explains some of the techniques he uses to capture the micro-world in action

From smoky to citrusy to peppery, the unique flavor profiles of wines are scrutinized and celebrated perhaps more than any other beverage. In the first episode of our wine science series, Dr. Gavin Sacks of Cornell University's Viticulture and Enology Program, details the chemical composition of wine and explains why you detect the faintest aromas of oak, flowers, or green pepper in your glass.

For over 70 years, no one had seen the oblong rocksnail. Declared extinct in 2000, the species was considered to be another native Alabaman mollusk gone and forgotten. But one day in the spring of 2011, biology grad student Nathan Whelan picked up a tiny rock and got a big surprise.

When Tim White isn't hunting for the remains of our ancestors or working on those fossil-finds at the National Museum of Ethiopia, he's stationed in a museum-like office at the University of California, Berkeley, where he directs the Human Evolution Research Center. From snake skins to ancient skulls, White's office is not short on artifacts.

For centuries, maple syrup producers across New England and Canada harvested sap by drilling into the bark of fully grown wild trees. While commercial syrup producers have adopted vacuum pumps and plastic tubing to aid these efforts, recent experiments at the University of Vermont's Proctor Maple Research Center may further pull the industry from its pastoral roots. By vacuum-sucking sap directly from the cut tops of juvenile trees, the researchers increased syrup production 5 to 6 times per acre compared to the traditional sap collecting methods.

In the second episode of our wine science series, Out of the Bottle, Dr. Gavin Sacks of Cornell University's Viticulture and Enology Program translates popular wine jargon such as "breathing," "corked," and "wine tears" into chemistry you can understand. He'll also give you some tricks you can use to experience the versatility of wine.

Avoiding belligerent bus drivers or unwitting tourists popping out of taxis are just a few of the more obvious risks of riding a bike through city streets.Yet there could be another inconspicuous and nearly unavoidable danger that could take a toll on your health: air pollution. Identifying how hazardous exercise can be in an urban environment filled with noxious particles in the air is the goal of a new study by Columbia University researchers Steven Chillrud and Darby Jack. Using biometric sensors, a wearable pollution monitor, and GPS, the study will detail participants' exposure to toxins as they cycle through city streets.

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.

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.

In the second episode of Science Friday and HHMI's series "Breakthrough: Portraits of Women in Science," three scientists share stories about India's first interplanetary mission—a mission to Mars. With limited time and budget to design and launch the satellite—called MOM (for Mars Orbiter Mission)—Seetha Somasundaram, Nandini Harinath, and Minal Rohit spent long hours in the clean room, followed by tense and exciting moments tracking the satellite as it entered Mars's orbit. Their efforts helped India become the first nation to successfully reach the Red Planet on its first attempt.

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.

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.

How beasts of burden do the locomotion.

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.
