Sharkskin = Swimsuit

posted by ranjankumar prajapati on

Sharkskin-inspired swimsuits received a lot of media attention during the 2008 Summer Olympics when the spotlight was shining on Michael Phelps.

Seen under an electron microscope, sharkskin is made up of countless overlapping scales called dermal denticles (or "little skin teeth"). The denticles have grooves running down their length in alignment with water flow. These grooves disrupt the formation of eddies, or turbulent swirls of slower water, making the water pass by ...

Did You Know That Zara Hartshorn Has A Rare Genetic Disease That Makes Her Look…

posted by kanhu charan on

Zara Hartshorn,16, from Yorkshire, UK was born with a rare genetic condition called lipodystrophy. Only about 2,000 people in the world and barely 30 in the UK are said to be affected by the extremely rare disease. Zara herself has inherited it from her mom Tracey while her older sister Chloe doesn’t have it and looks like any other girl her age.
Because of her condition Zara’s skin lacks elasticity which makes it look all wrinkled and twisted. What is more, the disease can lead to lung a ...

Butterfly Wings Inspire Holographic Solar Panel Coatings

posted by ranjankumar prajapati on

University of Pennsylvania Engineering Professor Shu Yang and her team have mimicked the reflective and water-resistant properties of butterfly wings to create a material that could coat solar panels and increase their output by keeping them clean and dry. The efficiency of solar panels takes a major drive when moisture and debris collect on their surface, so this inventive nature-inspired solution could keep them working at their maximum efficiency, not to mention the iridescence would be beaut ...

Fireflies Inspire Better, Cheaper LEDs

posted by ranjankumar prajapati on

The iridescence of butterfly wings have inspired holographic solar panel coatings, water strider insects have inspired water-striding robots, bumblebee behavior is inspiring better computers and that's just scratching the surface. Now, it's the firefly's turn.

The structure of the firefly's lantern has led to the development of anti-reflective LED lenses that are cheaper and make the technology even more efficient. Researchers from Korea Advanced Institute of Science and Technolog ...

3D-printed robotic bat wing holds new possibilities for small aircraft

posted by ranjankumar prajapati on

Brown University researchers are taking a closer look at the anatomy of bat wings and how they can be used to inspire new possibilities for small aircraft. Yep, just like bats inspired the sketches of da Vinci's flying machines they have also inspired the researchers who are delving into the flight secrets of bats. And they've begun with a robot imitation.

Their robotic bat wing -- an eight-inch mimic has plastic bones created with a 3D printer, "skin" made of silicone e ...

Squid beak inspires more comfortable medical implants

posted by ranjankumar prajapati on

The animal kingdom has been used for inspiration in the medical field in all sorts applications, from electric eels inspiring self-powering implants to spider webs inspiring artificial skin and it looks like the inspiration keeps coming. Researchers at Case Western Reserve University have developed a material for medical implants based on the properties of a squid's beak.

The tip of a squid's beak is harder than human teeth, but the base is as soft as the animal’s Jello-like body, ...

Creating The World's Strongest Artificial Muscles

posted by ranjankumar prajapati on

Nature really knows how to get design right. When it comes to muscles, Mother Nature has come up with a brilliant structure. But could the structure be even stronger? Scientists from the NanoTech Institute at the University of Texas at Dallas are coming up with a way to use carbon nanotubes as the material for muscles modeled after natural structures.

Fast Company notes, "By observing the inner workings of an octopus's leg or an elephant's trunk, scientists have created muscl ...

Robotic Hedgehogs to Explore Moons and Asteroids

posted by ranjankumar prajapati on

Stanford University, MIT and NASA are working together on the next big thing in space exploration: robotic hedgehogs. The spiky ball-like autonomous machines would be capable of rolling around and collecting data on super-low gravity moons and asteroids, with Martian moon Phobos as their first planned destination.

The design includes a mother spacecraft called the Phobos Surveyor that would carry several robo-hedgehogs to Phobos where they would tumble out and then roll, hop and b ...

Spider Webs Offer Biomimetic Inspiration for Dew Catchers in Developing Countries

posted by ranjankumar prajapati on

With the help of a scanning electron microscope, Chinese scientists have figured out the secret architecture to spiders' webs that make them incredibly effective at catching dew. Cracking into the mystery could mean that the same structures can be duplicated in fog catchers for developing nations, creating effective yet inexpensive methods for helping communities with scarce or polluted water sources. PhysOrg reports how it works: "The secret... lies in the silk's tail-shaped protein fibres ...

How One Day Everything Could Be Recycled

posted by ranjankumar prajapati on

Chances are you’ve heard about the Texas company that recently announced it was able to produce a working handgun on a 3-D printer. After assembling the gun out of printed plastic parts, the firm’s founder, Cody Wilson, took it out to a shooting range and successfully fired some .380 caliber bullets. He calls his creation “The Liberator.”

Chances are you haven’t heard about the 3-D printed working bionic ear made by Princeton and Johns Hopkins scientists. Or the University of Mich ...
