Bugs' eyes inspire new super-wide-angle camera

By - May 1, 2013 5 Pictures
Contrary to what certain cartoons may have us believe, insects’ compound eyes don’t produce a grid of tiny identical images. Instead, each of their many optical facets supply one unique section of a single composite image – sort of like the individual pixels that make up one digital image. Now, a team of scientists has replicated that eye structure, to create an ultra-wide-angle camera. Read More

Nano-suited insects survive in a vacuum

By - April 24, 2013 7 Pictures
Whether you're a researcher wishing to study living insects in conditions requiring a lethal vacuum, or you're that insect in the vacuum simply wishing not to die, scientists have found a solution to your problem. Using only a common chemical and a scanning electron microscope (SEM), a team at the Hamamatsu University School of Medicine developed a process that allows insects to survive in a vacuum of about a millionth of atmospheric pressure. Not just a new technique in biologists' toolkit, this research adds a small piece to our understanding of how life – insect, human, or otherwise – might be sustained outside the narrow constraints our bodies demand.

Cicada wings inspire new approach to antibacterial surfaces

By - March 7, 2013 1 Picture
Imagine if you took a water balloon and placed it on a bed of widely-spaced blunt nails. While the nails wouldn’t be pointy enough to pierce the balloon’s rubber skin, eventually the weight of the water would cause the rubber suspended between the nails to rupture. Well, it turns out that the clanger cicada uses the same principle to kill bacteria that settle on its wings. That finding could result in a new generation of antibacterial materials. Read More

K-abeilles Hotel is a shelter for bees – and humans

Bees are having a tough time at the moment, and it’s largely down to their relationship with us humans. Not only are they combating pollutants affecting the quality and color of their honey, but studies are also linking pesticide use to what is known as Colony Collapse Disorder. French architecture studio AtelierD has designed a pavilion for both bees and humans alike, that whimsically hopes to redress the delicate balance between the two species. Read More

VelociRoACH: A tiny robotic cockroach with a need for speed

By - January 14, 2013 5 Pictures
The common cockroach may make your skin crawl, but it turns out the household pest is the perfect model for miniature legged robots. That's why Duncan Haldane and his colleagues at the University of California, Berkeley, have been studying the six-legged pests to improve their millirobots. Their latest creation, the VelociRoACH, is made primarily out of cardboard and measures just 10 cm long, yet it can run 2.7 meters per second, making it the fastest robot of its size, capable of covering 26 times its body length in a single second.

Harvard's Robobee learning to fly

By - October 9, 2012 2 Pictures
Harvard researchers are getting closer to their goal of developing a controllable micro air vehicle called the Robobee. The tiny robot was already capable of taking off under its own power, but until now it was completely out of control. By adding two control actuators beneath its wings, the robot can be programmed to pitch and roll. Read More

Scientists hope to put artificial bee brains in flying robots

By - October 2, 2012 1 Picture
Honey bees are fascinating creatures. They live harmoniously in large communities, divided into different castes, with some of the worker bees heading out on daily expeditions to gather nectar and pollen from flowers. Already, a study has suggested that the efficient method in which bees visit those flowers could inspire the improvement of human endeavors such as the building of faster computer networks. Now, scientists from the Universities of Sheffield and Sussex hope to build a computer model of the honey bee’s brain, with the ultimate hope of using it to control tiny autonomous flying robots.

How bumblebees might get you faster overnight deliveries

By - September 24, 2012 4 Pictures
By studying the behavior of bees, a group of researchers at Queen Mary University of London has documented and modeled the way in which the insects can fly from flower to flower and then come back to their hives expending the least amount of time and energy. The findings might lead to better, much more flexible ways to deal with problems ranging from building faster computer networks to creating more powerful microchips. Read More

Scientists develop remote control system for cockroaches

By - September 5, 2012 3 Pictures
Much to the annoyance of home-owners everywhere, cockroaches are amazingly tough, and they’re able to squeeze into remarkably small spaces. These are some of the same qualities that researchers would like to see in tiny reconnaissance robots that could perform tasks such as searching earthquake-damaged buildings for survivors. Such adaptable, robust mini-robots would be quite challenging to create, however. A team of scientists from North Carolina State University are working on an alternative – sensor-equipped real cockroaches that are remotely controlled by human operators. Read More
