The diving bell spider builds its own underwater air tanks
by Larra Morris
The Diving Bell Spider (Argyroneta aquatica) is the only spider species that lives its entire life underwater.
It accomplishes this amazing feet by maintaining subsurface air bubbles. The spider’s body is covered with tiny hairs. Air bubbles adhere to that textured surface. The spider then weaves protective cases for these air bubbles with its silk. It attaches these air tanks to underwater plants and rocks and then climbs inside.
In addition to maintaining the air inside the bubble, the spider silk cover functions like a gill, pulling breathable air out of the water. via Neatorama
Spider silk may be known for being extremely strong, yet it's also elastic – that's how it's able to both hold struggling prey, and alert spiders to that prey by transmitting vibrations caused by those struggles. With these dual qualities in mind, a Design Engineering postgrad from Imperial College London…
Not long ago, solar cells were all huge, heavy, stiff devices. Recently that's been changing—and the latest development is a new breed of cells which are thinner than spider silk and can even be wrapped around objects as small as a human hair. According to research published in Nature Communications, a team…
Growing new organs and tissues outside the body is the bleeding edge of biomedical research. Just imagine: if doctors could grow replacement hearts or kidneys from a patient’s own stem cells, that patient would no longer have to face the agonizing prospect of waiting to find a suitable donor. The…
In this episode of Chalk Talk, Amelia Dalton and Brian Carlson from NXP investigate NXP’s S32G3 vehicle network processors that combine ASIL D safety, hardware security, high-performance real-time and application processing and network acceleration. They explore how these processors support many vehicle needs simultaneously, the specific benefits they bring to autonomous drive and ADAS applications, and how you can get started developing with these processors today.
