When a missile or meteor strikes the earth, the havoc above ground is obvious, but the details of what happens below ground are harder to see. Duke University physicists have developed techniques that enable them to simulate high-speed impacts in artificial soil and sand in the lab, and then watch what happens underground close-up, in super slow motion.
Nautilus Live yesterday posted this wonderful video of the capture of a sperm whale by the ROV Hercules. The ROV – remotely operated underwater vehicle – was tethered 598 meters (1,962 ft) below the Gulf of Mexico off the coast of Louisiana at the time.

Burmese pythons were imported to Florida as pets. Now tens of thousands of them are in the wild and they’re eating everything. Check out this video from the New York Times. Yikes!
If you like science, and you like spending a day along a coastline – and if you live in the Pacific Northwest or Alaska – this citizen science project might be for you. It’s called COASST, and it’s a group of scientists and volunteers who monitor beach-cast seabird carcasses to learn more about bird populations in their local ecosystems.
A pulsar is a rapidly spinning neutron star which is the small, incredibly dense remnant of much more massive star. How dense? A teaspoon of matter from a neutron star weighs as much as Mount Everest.
The goal of the mission is to find out how the human body responds to a prolonged stay in space. Watch the launch and watch the arrival.
