In order to meet the heavy load/long range transport requirements of life on the moon, NASA recently teamed up with Goodyear to review and redesign some 40-year-old technology in the shape of the airless tires first seen on the Lunar Rover Vehicles of Apollo missions.
The mesh on the Apollo LRV tire was woven from zinc-coated piano wire, the tread formed from a series of titanium-alloy chevrons and the inner frame comprised of a partly rigid metal "bump stops" to minimize impact damage to the aluminum hub. Looking like a skeleton of a car tire, the design worked so well on the LRV because it only needed to support 60 pounds (360 pounds Earth weight) of weight over short distances.
The Goodyear-NASA team says that vehicles closer to home might also benefit from this project's research as tough airless, all-terrain tires could be used on "mobility critical small vehicle applications; such as fire fighting support vehicles, robotic vehicles, off road and desert vehicles, trash hauling and mining equipment.

The smallest ever free-flying aircraft to hover and climb with flapping wings has been developed by California firm Aeronvironment.
The "nano air vehicle" is the size of a small bird or large insect, and can hover indoors under radio control. "It is capable of climbing and descending vertically, flying sideways left and right, as well as forward and backward, under remote control," says the company.

Low levels of electrical energy, delivered straight to the nerve fibers in the spinal cord, can disrupt the signals that certain chronic pain conditions send to the brain, and replace them with a much more pleasant tingling sensation.
Developed by St Jude Midical, the Eon Mini is the world's smallest rechargeable neurostimulator. It is the size of a silver dollar and weighs only 29g (1oz). It sits under the skin of the buttock or abdomen, and its rechargeable battery should last nearly 10 years.
It can be programmed by remote control to treat as many as eight different chronic pain areas and, in doing so, it can get many patients with chronic pain off morphine and back into a semblance of normal life.

A new procedure being developed in Italy aims to turn blocks of wood - specifically red oak, rattan and sipo - into artificial bones. Wood-derived bone substitutes could allow faster and more secure healing than currently available with metal and ceramic implants.
To create the bone substitute, a block of wood is heated until all that remains is pure carbon, which is basically charcoal.The scientists plan to implant them into humans after first trialling the technology in large animals.
The first FDA approval of a synthetic bone implant (or bone void filler) was granted in 1992 to Pro Osteon, a calcium phosphate material that mimics hydroxyapatite manufactured from coral

Clinicians at Heidelberg University Hospital in Germany have announced the first implantation of the latest DeBakey left ventricular assist device (LVAD).
The world's smallest machine of its type, it is made out of titanium and plastic, and provides direct measurement of cardiac output without having to estimate, as in competing devices.
The new miniature device is light, easy-to-handle and can be monitored and controlled externally.

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed an electric transport system where the vehicles get their power needs from cables underneath the surface of the road via non-contact magnetic charging.
Rather than relying on battery technology, the OLEV (Online Electric Vehicle) picks up charge using a non-contact magnetic charging method (where a power source is placed underneath the road surface and power is wirelessly picked up on the vehicle itself) so it doesn't matter if the car is moving or parked up, it still receives power.
As a possible solution to traffic congestion and to improve overall efficiency by minimizing air resistance and so reduce energy consumption, the test vehicles followed the power track in a convoy formation. It's thought that road safety and vehicle efficiency could be enhanced further by adopting technology that would allow the OLEV to drive itself in convoy mode.

This new innovation in bicycles is called the “Kilobike”. It is designed to “expand the identity and usage of today’s kids bikes.”
This bike has the capability to expand along the years 6 to 12 years, multiple settings. Made to provide ergonomically correct conditions and “good outlook at all stages.”
