In 2010, construction crews found the hull of a very old ship, buried at the site of the World Trade Center towers. Using dendrochronology, scientists now know how old the ship is and what city it was made in.
Meg Gannon at LiveScience has a good, well-detailed story on how the scientists were able to learn about the ship by studying the tree rings visible in the timbers used to build it. Fair warning, the LiveScience website is just a mess of ads and rollover popups. Gannon's article is worth reading, despite all that.
"What makes the tree-ring patterns in a certain region look very similar, in general, is climate," said the leader of the new study, Dario Martin-Benito, who is now a postdoctoral fellow at the Swiss Federal Institute of Technology (ETH) in Zurich. Regional ring patterns arise from local rain levels and temperatures, with wetter periods producing thicker rings and drier periods producing smaller rings, he said.
...The ship's signature pattern most closely matched with the rings found in old living trees and historic wood samples from the Philadelphia area, including a sample taken during an earlier study from Independence Hall, which was built between 1732 and 1756.
OK, it’s not quite Dr. Crusher’s dermal regenerator (seen above), but Arizona State University researchers have demonstrated a laser system for sealing wounds. The system involves a sealing paste — made from silk protein mixed with gold nanorods — that bonds with skin when heated with a laser. From IEEE Spectrum: To use a laser […]
There’s scientific truth to the saying that you never forget how to ride a bike. Even if you can’t remember phone numbers, birthdays, or where the hell you parked your car, it’s likely that even if you haven’t been on a bicycle in decades, you can climb on and ride away just fine. Why? Neuropsychologist […]
The Moroccan Euphorbia resinifera plant produces a resin so spicy that it attains a whopping 16,000,000,000 on the Scoville scale, 10,000x hotter than a Carolina reaper chili.
There are two times you never want to just “eyeball” it: Conducting brain surgery and matching shades of paint for your walls. Whether you’re painting or repainting, make sure you’re never just “close enough” to the color you want. Not when the Nix Mini Color Sensor can scan and match any color perfectly. Small enough […]
In photography as in film, all the real artistry is in post-production – increasingly so, with the new possibilities cropping up in digital imaging. If you’re ready to get serious about your photography, may we suggest HDR Projects 2018 Pro. As working photographers can tell you, this imaging software can help you re-imagine even the […]
A picture can be worth a heck of a lot more than just a thousand words. If you’ve squinted for ages trying to get just the right photo, you might have the right passion for a career behind the camera. You might even have the right equipment, but do you have the know-how? The Beginner-To-Expert […]
