Mosquitoes learned to associate smells with vibrations mimicking human hand movements produced by “the vortexer” machine.
Child’s brain rewires following double hand transplant
This is the incredible story of Zion, the first quadruple amputee child in whom researchers observed massive brain reorganization before and after the hand transplant.
Designed for astronauts, the RoboHand can double your hand’s strength — and soon, it will be available on Earth
Handy.

For the first time in history, researchers restore voluntary finger movement for a paralyzed man
Using two sets of electrodes, scientists have successfully restored finger movement in a paralyzed patient for the first time in history. The results could be the starting point to developing methods that would allow people around the planet to regain limb mobility.
Did human hands evolved to pack a punch?
We humans arguably came to dominate the world thanks to our dexterous hands, which allow gripping tools and manipulating objects. An eccentric professor at University of Utah agrees, but with a twist. According to David Carrier there’s a secondary evolutionary driver that led our hands to reach their current shape and dexterity: fist punching. To illustrate his hypothesis, Carrier turned to a macabre experiment in which cadaver hands clenched in various positions, from open hand to a good old sucker punch fist, were bashed against a dumbbell. Carrier showed that a fist could handle the strike with double the force supported by an open hand before bones started to break.
Scientists find 1.85 million year old human-like bone
Anthropologists have discovered the oldest known fossil of a bone resembling that of humans; the 1.85 million year old bone is the oldest evidence of a ‘modern’ hand and suggests that ancient humans may have been much larger than previously thought. A key feature that distinguishes humans from other species is the ability to create and use tools. But in order to
Early human ancestors used their hands much in the way as we do
After analyzing key hand bone fragments from fossil records, a team of anthropologists conclude that pre-homo human ancestral species, such as Australopithecus africanus, used a hand posture very similar to that of modern humans. Considering fossil tools used for scrubbing off meat as old as 3.3 million years have been found, it may just be that our early ancestors weren’t all that different from good ol’ superior homo sapiens sapiens. Well, as far as hands go at least.
Human-computer interface relays touch out of thin air
Using ultrasound radiation, researchers at University of Bristol (UK) have devised a computer interface that basically allows users to interact with a digital screen without touching it. Sure the Kinect or Leap Motion does this already, the catch is that this system also provides haptic (touch) feedback. So, whenever a user traces a motion in front of the system, not
