BirdBot's leg mechanics are automatically water proof; all motors are located in the robot's trunk, far away from its feet. Here the mechanics that produce joint torques, tendon forces, and ground contact are water-proof. Theoretically, BirdBot could walk through water (possible future work).

Watch emu-inspired robot legs that use less energy to run

Robotic legs that mimic flightless running birds like emus and use just two motors per leg can run more efficiently than more complex devices

While the purpose of this image was to focus on the bright star at the center for alignment evaluation, Webb's optics and NIRCam are so sensitive that the galaxies and stars seen in the background show up. At this stage of Webb?s mirror alignment, known as ?fine phasing,? each of the primary mirror segments have been adjusted to produce one unified image of the same star using only the NIRCam instrument. This image of the star, which is called 2MASS J17554042+6551277, uses a red filter to optimize visual contrast.

A colour-enhanced scanning electron microscope (SEM) image of Magic mushrooms (Psilocybe cubensis). These spores will grow into the fungus that is Psilocybe cubensis , or the magic mushroom. When ingested, this fungus causes euphoria, hallucinations and altered perception of time. Each spore of this strain is approximately 8 by 11 um. Magnification is x660 when printed 10 cm wide.

MEDYKA, POLAND - MARCH 09: Iryna Holoshchapova, a Ukrainian refugee who fled the embattled city of Mykolaiv, shows a video on her smartphone of a friend's apartment block in Mykolaiv on fire following a Russian attack as she, her son Tibor and mother Halina rest in a heated tent at the Medyka border crossing on March 09, 2022 in Medyka, Poland. Yulia said her friend was not in the building when it was struck. Over one million people have arrived in Poland from Ukraine since the Russian invasion of February 24, and while many are now living with relatives who live and work in Poland, others are journeying onward to other countries in Europe.
