If you haven't heard of the Quadrantids, don't worry. Even NASA calls them "a little-known meteor shower named after an extinct constellation." But in the Northern Hemisphere, they can be well worth watching.
Toyota, Honda and Hyundai have announced that they plan to build hydrogen-powered cars in the next few years. But is America ready for automobiles fueled with liquid hydrogen? Take a test-drive in one and find out.
From the journal Nature, so-called "super Earths" that orbit distant stars are among the most common planets in the galaxy. Now scientists have done a detailed analysis of one super Earth's atmosphere. They say it looks like this planet must have exotic clouds.
Research suggests that speaking another language fluently changes what you pay attention to and how you remember events. But some say the idea that language can make you see and think differently is overblown.

Phosphorus is one of the nutrients that plants need to grow, and for most of human history, farmers always needed more of it. But excess phosphorus, either from manure or manufactured fertilizer, can run off into streams and lakes and become an ecological disaster.
Order cod in a restaurant on Cape Cod, and you might assume you're buying local. But the fish that gave the Cape its name are now so depleted that restaurants are serving cod imported from Iceland. Some activists think it's time America developed a taste for the less popular fish still present in the waters off the Cape.
Archeologists who study the people who lived in the Arctic thousands of years ago are in a race against time. Coastal settlements are being washed away by erosion, storm surges and other climate changes related to global warming. Clues to the past that were frozen intact in permafrost for thousands of years are melting and being destroyed by the elements. Archeologists are looking to climate scientists to predict where the erosion will be the fastest so they can pinpoint their research on the places that will disappear the soonest. Until now the predictions have largely been too coarse to provide much guidance. But the National Park Service is trying to change this. It's funding research that supposed to forecast the threats that more than 100 coastal national parks face from sea level rise and storm surges due to climate change.
