Building Human Organs

latest science inventions

Oganovo is a company based in San Diego, California.

Their latest science invention is a technology (novogen) which allows living tissue cells to be assembled into patterns and complex structures, such as organs.

Organovo has partnered with Invetech. a company based in Australia, to develop a bio-printer.

The device prints (places) human cells in a three-dimensional matrix to construct human tissue.

"Building human organs cell-by-cell was considered science fiction not that long ago," says Fred Davis of Invetech.

Currently, the bio-printer can grow blood vessels. It is anticipated that within five years the device will construct arteries and by 2020 sophisticated organs will be built by the device.

Water Drop Lens

science-inventions

Physicist and inventor, Bruno Berge, has created a liquid optical lens.

Using a process known as electro-wetting, a water drop is deposited on a metal substrate and covered by a thin insulating layer. When a voltage is applied to the metal, it modifies the angle of the liquid drop.

The liquid lens is comprised of two liquids, water and oil, one is a conductor while the other is an insulator. A variation in the voltage causes a change to the curvature of the liquid to liquid interface, which changes the focal length of the lens.

The use of liquids allows for low cost construction. There are no moving parts and electrical consumption is extremely low. The lens has a large inverse focal length range, quick response, high optical quality and can operate in a wide temperature range.
