The Continuing Merger of Man & Machine:
- DARPA’s Pet-Proto Robot Navigates Obstacles:thanks Carsten Kolassa!
- 1st Bionic leg propels man up 103 flights:
- ‘Terminator’ arm is world’s most advanced prosthetic limb:
- Batteries not required, just plug into ear cells:
The team behind the technology used a natural electrochemical gradient in cells within the inner ear of a guinea pig to power a wireless transmitter for up to five hours.
The technique could one day provide an autonomous power source for brain and cochlear implants, says Tina Stankovic, an auditory neuroscientist at Harvard University Medical School in Boston, Massachusetts.
The device works well for short durations but long-term use of the electrodes risks damaging the sensitive tissue inside the ear. The next step will be to make the electrodes even smaller, reducing their invasiveness.
Stankovic says that this is proof of concept that biological sources of energy exist that have not yet been fully considered. “A very futuristic view is that maybe we will be able to extract energy from individual cells using similar designs,” she says.
- Assembly of nano-machines mimics human muscle:
…for the first time, Giuseppone’s team has succeeded in synthesizing long polymer chains incorporating, via supramolecular bonds (1), thousands of nano-machines each capable of producing linear telescopic motion of around one nanometer. Under the influence of pH, their simultaneous movements allow the whole polymer chain to contract or extend over about 10 micrometers, thereby amplifying the movement by a factor of 10,000, along the same principles as those used by muscular tissues. Precise measurements of this experimental feat have been performed in collaboration with the team led by Eric Buhler, a physicist specialized in radiation scattering at the Laboratoire Matière et Systèmes Complexes (CNRS/Université Paris Diderot).
These results, obtained using a biomimetic approach, could lead to numerous applications for the design of artificial muscles, micro-robots or the development of new materials incorporating nano-machines endowed with novel multi-scale mechanical properties.
- What made us human? Being ARMED with lethal ranged weapons -Early kill-tech let us beat Neanderthals, dominate world:
“When Africans left Africa and entered Neanderthal territory they had projectiles with greater killing reach,” explains Professor Curtis Marean, an expert in stone weapons who was instrumental in the research.
“These early moderns probably also had higher levels of pro-social (hyper-cooperative) behavior. These two traits were a knockout punch. Combine them, as modern humans did and still do, and no prey or competitor is safe,” he adds. “This probably laid the foundation for the expansion out of Africa of modern humans and the extinction of many prey as well as our sister species such as Neanderthals.”

- Nyodyme from Imagina Technologies (already SOLD OUT):
Nyodyme Magnets give their users the ability to “sense” electromagnetic waves. The technology behind the Nyodyme Magnet is created from a beautiful gold and nickel-plated neodymium magnet that is placed within Imagina’s specially made glue that has magnetic iron filings mixed into it to enhance the vibrations.
- Military makeup will protect soldiers from bomb-blast burns:
A new type of camouflage makeup is able to protect wearers from skin burns. Scientists at the University of Southern Mississippi developed the makeup for use in combat situations, but the team plans on developing a transparent version for firefighters. The new material acts like sunblock, forming a barrier thinner than a sheet of paper that can protect skin from extreme heat for up to 15 seconds. After that time, the makeup itself may rise to a temperature where first-degree (mild) burns may occur, but the extra time should help soldiers to find shelter from any explosion. In some tests, the scientists found that the face paint shielded its test subjects for up to 60 seconds.
