Machine learning algorithms have successfully identified plant species in massive herbaria just by looking at the dried specimens. According to researchers, similar AI approaches could also be used identify the likes of fly larvae and plant fossils. From Nature:
There are roughly 3,000 herbaria in the world, hosting an estimated 350 million specimens — only a fraction of which has been digitized. But the swelling data sets, along with advances in computing techniques, enticed computer scientist Erick Mata-Montero of the Costa Rica Institute of Technology in Cartago and botanist Pierre Bonnet of the French Agricultural Research Centre for International Development in Montpellier, to see what they could make of the data.
Researchers trained... algorithms on more than 260,000 scans of herbarium sheets, encompassing more than 1,000 species. The computer program eventually identified species with nearly 80% accuracy: the correct answer was within the algorithms’ top 5 picks 90% of the time. That, says (Penn State paleobotanist Peter) Wilf, probably out-performs a human taxonomist by quite a bit.
Such results often worry botanists, Bonnet says, many of whom already feel that their field is undervalued. “People feel this kind of technology could be something that will decrease the value of botanical expertise,” he says. “But this approach is only possible because it is based on the human expertise. It will never remove the human expertise.” People would also still need to verify the results, he adds.

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 […]
