Look out! The robots are coming - for an invasive fish species that is. Mosquitofish are one of the world’s most problematic invaders in freshwater lakes and waterways. Researchers have developed a robotic fish able to mimic one of its main natural predators: largemouth bass. The lifelike silicone robofish swim around scaring and stressing the mosquitofish with targeted attacks, depleting their energy reserves. Lower reserves means less energy to devote to reproduction…and could lead to fewer mosquitofish in the future. Hello faux-bot bass, bye-bye invaders!

How did an ancient shark survive one of Earth’s big extinctions? Like most shark movies, this one’s better in 3D. Using computing tomography, or CT imaging, and 3-D tools, this team rebuilt a Tristychius shark from the Paleozoic Era and explored its biomechanics in a way that’s never been done before. “Tristy” evolved into a sophisticated suction feeder, snagging hard-to-capture food resources like burrowing prey, and about 50-million years before other fish did. The researchers say these new imaging methods are releasing a motherlode of data about fossils.

Rice can survive flooding like no other crop… at least not yet. Scientists compared the flooding response of rice with three plants… domesticated and wild tomatoes and this alfalfa-like legume. An unprecedented look at whether and how genes at the root tips activate under water. Turns out all four share genes activated in response to flooding, but rice response is better coordinated and more robust. They hope to take advantage of what they’ve learned to help activate flood resistance in other crops.

This new way to diagnose skin cancer could cut way back on the need for biopsies. Engineers are generating images of cancer hotspots using the same kind of shortwave rays used in cellphones and security scanners. The technology spots cancer just like a scanner spots your keys, and it’s as accurate as lab testing. The goal is to build a handheld device for instant diagnostics, reducing the need for biopsies. These handheld devices could even be placed in pharmacies for quick check-ups.

And there you go, see you next time with 4 more awesome discoveries, funded by NSF!
