Can We Eat Our Way To A Healthier Microbiome? It's Complicated

Originally published on Mon November 25, 2013 10:27 am

While no one's sure which foods are good for our microbiomes, eating more veggies can't hurt.

When our colleague Rob Stein got his microbiome analyzed recently in the name of science journalism, we were totally fascinated.

As Stein noted, it may be possible to cultivate a healthier community of bacteria on and inside us by modifying our diets.

Stein was advised to eat more garlic and leeks for his. But we wondered: Are there other foods that promote a healthy microbiome in most people?

What's the difference between a hurricane, a typhoon and a cyclone? Nothing more than location.

As Super Typhoon Haiyan slams into the Philippines, we here at the Two-Way found ourselves revisiting old ground about the nature of tropical storms. In case you need a refresher (as we did), here is the lowdown:

Astronomers Find Bizarre 'Lawn Sprinkler' Asteroid

Originally published on Fri November 8, 2013 5:11 pm

These NASA/ESA Hubble Space Telescope images reveal a never-before-seen set of six comet-like tails radiating from a body in the asteroid belt designated P/2013 P5.

Astronomers using both ground- and space-based telescopes have discovered a new kind of asteroid that sports not one, but six comet-like tails, and has been described as looking something like a rotating lawn sprinkler.

P/2013 P5 was first spotted with the Pan-STARRS 1 telescope at the top of Haleakala volcano in Maui, Hawaii, in August and then followed up with more detailed observations using the Hubble Space Telescope.

How Tall Is The Washington Monument? Surveyors Take To The Top

The National Geodetic Survey doesn't often get the opportunity to take detailed measurements of the massive stone obelisk that sits in the middle of Washington, D.C.

But a 2011 earthquake in nearby Mineral, Va., damaged the Washington Monument enough that to repair it, the tower had to be wrapped in scaffolding. That gave surveyors access to the very top of the structure.

The Myth of the Woolly Bear

Legend holds that the length of a woolly bear caterpillar's color bands can be used to forecast how severe the winter weather will be. The myth dates back to colonial American folklore but was popularized by a 1948 study. SciFri finds out if there's any truth to the lore, and what the caterpillar's fuzzy bristles are really used for.

India and NASA Home In on Mars

This week, India launched Mangalyaan, its first robotic mission to orbit Mars and probe its atmosphere. Only Russia, Europe, and the U.S. have successfully orbited the planet. Joan Johnson-Freese, a professor in national security affairs, and planetary scientist Bruce Jakosky discuss the Indian space program, as well as NASA's upcoming mission to the Martian atmosphere.

Navigating Dietary Supplement Regulations

Echinacea, vitamins, and other dietary supplements have become a $5 billion industry, but the products don't need to be pre-approved by the FDA before they go on the market. How do we know what is really in our supplements? What regulations are currently in place? How can we keep ourselves safe and informed?

So Far, No Silver Bullet to Stop Lethal Bat Fungus

Since its appearance in the U.S. seven years ago, white-nose syndrome has decimated bat populations across eastern North America. Scientists say they've determined the culprit--a soil-dwelling fungus called Pseudogymnoascus destructans--and now they're investigating novel ways to stop it, including antifungal bacteria.

Biosecurity for the Age of Redesigned Life

Forget dissecting frogs and building potato batteries. High school students today are learning genetic engineering--and some are even redesigning life. Bioethicists and the FBI have taken note and are rethinking biosecurity for the synthetic biology revolution.
