A bright idea! Genetically engineered plant glows so brightly it can be used as a LAMP

Many people set the mood for a romantic night in with candles, but now they could use a genetically engineered glowing plant for a date with a difference.

A light-producing plant called Starlight Avatar that glows like a firefly has been created by U.S. scientists.

Bioengineers spliced genes from bioluminescent bacteria with a pot plant to create the plant, which can be used as a lamp in the dark.

Bioglow, the company behind the innovation, which is based in St Louis, Missouri, claim Starlight Avatar is the first light-emitting plant.

It is a genetically-modified version of a regular pot plant called Nicotiana alata and glows continuously during its lifetime.

The firm is auctioning the first batch of glowing shrubs and taking pre-orders for further plants it is are currently nurturing.

This is excellent idea for changing the lamps in each city and town and bringing more natural surroundings  in the already polluted cities.

We are constantly using our smart devices to capture images for different reasons any single day; but how may of us really appreciate it?

Photography has being getting better since the beginning in the 17th century.

So in order o understand the process let’s jump together into the story and some nice details.

The word photography comes from two Greek words meaning “light” and “drawing.” Photography is the process and the art of creating fixed images using the action of light on a chemically prepared surface.

The history of photography has roots in remote antiquity with the discovery of the principle of the camera obscura and the observation that some substances are visibly altered by exposure to light. As far as is known, nobody thought of bringing these two phenomena together to capture camera images in permanent form until around 1800, when Thomas Wedgwood made the first reliably documented although unsuccessful attempt. In the mid-1820s, Nicéphore Niépce succeeded, but several days of exposure in the camera were required and the earliest results were very crude.

Niépce’s associate Louis Daguerre went on to develop the daguerreotype process, the first publicly announced photographic process, which required only minutes of exposure in the camera and produced clear, finely detailed results. It was commercially introduced in 1839, a date generally accepted as the birth year of practical photography.

So that sound pretty simple, but it really works?

Let’s start with the basic camera.

Here is a simple video to build the cheapest camera in the Universe.

I hope you can use it as a present or to have a nice time with children’s.
