Yes, there was a tunnel collapse at a former nuclear processing facility on Tuesday. No, you don't need to panic. Knowledge is power:

Big Bird is eight feet, two inches tall. That's big. The ostrich, the largest living bird is bigger, topping out around nine feet tall. But neither fictional nor factual birds can hold a candle to a new species of bird-like dinosaur called Beibeilong sinensis, which was likely around 26 feet long and weighed about 3 tons when fully-grown.

No, that was not a typo. It might seem counterproductive to take caffeine when you need to sleep, but some mice at Boston Children's Hospital would beg to differ.

The common lizard, as its name suggests, is common. Its range begins to the west in Ireland and stretches as far east as Japan, with an expanse that reaches as far north as the Arctic Circle and as far South as northern Italy. With so much of its range unoccupied by humans it's no surprise that Zootoca vivipara is a species of "least concern". But humans don't actually have to encroach upon the common lizard's habitat to cause the critter harm. We just have to turn up the heat.

Facebook's billion-plus users speak a plethora of languages, and right now, the social network supports translation of over 45 different tongues. That means that if you're an English speaker confronted with German, or a French speaker seeing Spanish, you'll see a link that says “See Translation.”

Just two weeks ago Amazon introduced the $200 Echo Look, a smart-home hub that includes a built-in camera to help evaluate your outfit before leaving the house. Now, the company has taken another step, introducing its flagship hub, the $229 Echo Show, which has both a 5-megapixel camera and a 7-inch touchscreen display.

If you speak about time in terms of a container being filled, you might have a tougher time gauging how much time it's taking for this cup to fill.

Yesterday, Mark Zuckerberg announced that Facebook is hiring 3,000 people to work on its community operations team, which reviews images, videos, and posts that users report. These new hires will join the 4,500 existing employees in an effort to minimize the reach of future events like the shooting of Robert Goodwin. It's a considerable-but-essential investment for Facebook, but it leads us to a basic question: Can't this job be automated?

Time travel is usually only possible in one direction: plodding ever-forward at the pace of a ticking second hand on a clock. We can't make leaps into the past or future, however much we'd enjoy the break from our present.

It's a big deal when people don't take the medications prescribed to them. In fact, studies estimate that patients failing to pop their pills—a problem known as non-adherence or noncompliance— costs the American health care system as much as $289 billion each year, and leads to roughly 10 percent of hospitilizations.

It's very important that you look at these pictures of stumpy-legged doggos. You know, for science.

The L-15B prototype attack jet made its grand debut in a ceremony last week. Fanfare—including giant red banners and uniformed PLAAF officers—suggest the People's Liberation Army Air Force (PLAAF) and Hongdu Aviation Industry Group have high hopes for this multi-role light fighter.

Last week, the Cassini spacecraft made its first dive through the gap between Saturn and its rings. It sent home some pretty spectacular pictures, and now NASA has stitched them together into a video. Behold:

Algae can be used for anything. You can grind it into cattle feed or squeeze it into jet fuel. You can even make it into algae butter. For now, algae-based products remain woefully expensive, but a group of California scientists is working on making them a whole lot cheaper.
