High-voltage catfish immune to their own shocks
Malapterurus beniensis may look like a harmless catfish lounging on the bottom of a tank, but these creatures are far from benign. Packing a powerful 300 V electric shock, the fish usually reserve their pyrotechnics for stunning prey. ‘We always wear thick rubber gloves when handling the fish’, chuckles Stefan Schuster from the University of Bayreuth, […]
Head bobbing gives pigeons a sense of perspective
Having your eyes stuck on the side of your head is great to avoid turning up on someone else’s menu. Providing almost 360 deg vision, wide-set eyes give pigeons the best chance of escape. But they also have lousy stereo vision. With little overlap between the views of both eyes, no one knew whether the […]
The design of a smart robot for colonoscopy is challenging because of the limited available space, slippery internal surfaces, and tortuous 3D shape of the human colon. Locomotion forces applied by an endoscopic robot may damage the colonic wall and/or cause pain and discomfort to patients. This study reports a Soft […]
Scientists have published the first complete, gapless sequence of a human genome, two decades after the Human Genome Project produced the first draft human genome sequence. According to researchers, having a complete, gap-free sequence of the roughly 3 billion bases (or ‘letters’) in our DNA is critical for understanding the full […]
Designers of legged robots are challenged with creating mechanisms that allow energy-efficient locomotion with robust and minimalistic control. Sources of high energy costs in legged robots include the rapid loading and high forces required to support the robot’s mass during stance and the rapid cycling of the […]
Color Change in Cephalopods
This paper describes how Cephalopods are capable of blending in with their environments through multiple layers of skin. Their camoflauge is unique because they can mimic color, movement, texture, and light, allowing them to blend in to a greater extent.

Scientists are using lasers and a goggle-wearing parrot for the design of flying robots of the future.
A barely visible fog hangs in the air in a California laboratory, illuminated by a laser. And through it flies a parrot, outfitted with a pair of tiny, red-tinted goggles to protect its eyes.

Miraculous skin metamorphosis for beached amphibious fish
Taking those first steps on land after emerging from the primordial swamp required a lot more than simply changing the way the earliest pioneers moved and breathed. The ancient innovators must also have sealed their skins to prevent water loss in the relatively dry surroundings. They may even have repurposed their external layer to absorb […]
News, Flexible wings take the effort out of swimming for diving penguins
Swimming with penguins in the wild is a mind-blowing experience. When the ‘mini torpedoes’ hurtle past, you can barely make out the animals’ shape, let alone their movements. This was the problem faced by Hiroto Tanaka and colleagues from the Tokyo Institute of Technology, Japan, as they tried to understand how […]
News – Lockheed Martin Is Reprogramming Cells To Bioproduce New Materials
Cells form the cornerstone of life, and Lockheed Martin (NYSE: LMT) is researching ways to create the building blocks of novel materials. In a new cooperative agreement with the Army Research Laboratory, Lockheed Martin material scientists will work with industry and Army scientists who design microbes to edit single-cell organism DNA.
