Human blood platelets grown in bone marrow-replicating bioreactor

Scientists have already successfully coaxed stem cells into becoming red blood cells, which could be used to create "man-made" blood for transfusion. Red blood cells, however, aren't the only component of human blood. Now, researchers at Harvard-affiliated Brigham and Women’s Hospital have also created functional human platelets, using a bioreactor that simulates the medium in which blood cells are naturally produced – bone marrow.

Squid sucker teeth could advance human technology

There seems to be no end to the proposed human technologies based on attributes of the squid. The animals' beaks have inspired a material that could be used for medical implants, their muscles may lead us to color-changing clothing, the chitosan in their "pens" has been used to create a proton-conducting transistor, and their movements served as the inspiration for a soft-bodied robot. Now, it turns out that the teeth inside the suckers on their tentacles might be the basis for materials that could be used in fields such as reconstructive surgery. Read More

Bird-inspired drones may be able to perch on power lines to recharge

Unmanned aerial vehicles (UAVs) are currently being considered for many applications, although one factor that a lot of people tend to gloss over is the aircrafts' limited battery range – being able to stay airborne for only 10 to 30 minutes at a time definitely limits their usefulness. Researchers at MIT, however, are developing a possible solution. They're working on a fixed-wing UAV that can perch on power lines and use their emitted magnetic fields to recharge its battery, before continuing on its way. Read More

Z-Man tech allows people to climb glass like geckos

Geckos are likely better climbers than any other animal, so it's no surprise that a number of researchers have tried to copy that ability via man-made technology. One group, from Stanford University, was particularly successful with a small climbing robot known as the Stickybot. Four years ago, we heard about how they were also looking into applying the Stickybot tech to a system that would allow humans to climb up vertical surfaces. Now, DARPA has announced the first successful demonstration of that system, known as Z-Man. Read More

MagnetoSperm could find use in drug delivery, or even baby-making

When it comes to moving simply but effectively through a liquid medium, few things are as good as sperm. This fact isn't lost on scientists, who have built tiny sperm-like robots (or even used "hijacked" sperm) in efforts to create new methods of targeted drug delivery, among other potential applications. The latest such endeavor has resulted in a batch of microrobots known as MagnetoSperm. Read More

Spider-inspired discs could be the new glue

In recent years we've seen a number of attempts at artificially replicating the strong-yet-light characteristics of spider silk. It turns out that the silk itself isn't the only thing that's inspiring scientists, however. Researchers from the University of Akron have recently created their own version of the "attachment discs" that spiders use to secure their silk fibers to surfaces, when building webs. These man-made discs could conceivably prove superior to conventional glues as a form of adhesive. Read More
