Secret of always-taut spider threads inspires new material. Why doesn’t a spider’s web sag in the wind or catapult flies back out like a trampoline? The answer, according to new research by an international team of scientists, lies in the physics behind a ‘hybrid’ material produced by spiders for their webs.

Pulling on a sticky thread in a garden spider’s orb web and letting it snap back reveals that the thread never sags but always stays taut – even when stretched to many times its original length. This is because any loose thread is immediately spooled inside the tiny droplets of watery glue that coat and surround the core gossamer fibres of the web’s capture spiral.

The researchers studied the details of thi...

Cubimorph is a modular interactive device that holds touchscreens on each of the six module faces and that uses a hinge-mounted turntable mechanism to self-reconfigure in the user’s hand.

A prototype for an interactive mobile device, called Cubimorph, which can change shape on-demand will be presented this week at one of the leading international forums for robotics, ICRA 2016, in Stockholm, Sweden [16-21 May]. There has been a growing interest toward achieving modular interactive devices in the human computer interaction (HCI) community, but so far existing devices consist of folding displays and barely reach high shape resolution.

Cubimorph is a mod...

For artificial photosynthesis to become a viable alternative to fossil fuels, the efficiency and speed of water oxidation ie into O2, H ions, and electrons–is one of the processes that must be improved. By accelerating formation of O-O bond in water oxidation, newly developed ruthenium catalysts could drive the reaction needed to efficiently store solar energy in the chemical bonds of clean fuels.

The 2 catalysts–complexes of ruthenium surrounded by binding molecules (ligands) containing phosphonate ...

3 researchers at the University of Freiburg has taken the science of using neural networks to understand the style of paintings done by human hands and applying it to modern photographs, one step further, by applying it to video.

Imagine if you could film a friend with your phone, as he wanders aimlessly down a road on the edges of a quaint village, then use an app to make it look like your friend was wandering through a Starry Night painting, by Vincent Van Gough? It appears the day may be coming when amateur and professional video/movie makers alike may be able to do such things wit...
