Smartphones can help grow vegetables

It is possible that in near future, you may be using your smartphone to grow your vegetables.

A Taipei, Taiwan-based company has developed a farm cube – a small enclosed ecosystem designed to grow plants indoors. The environment inside is automatically adjusted by the cube, but it can also be controlled through an app.

Instead of going outside to pick vegetables like lettuce, you could be harvesting your food inside your home, using a stack of farm cubes made by OPCOM.

Jack Ting, CEO, OPCOM tells: “In this one, the one cycle, around six weeks, 200 pieces or 100 pieces depending on different vegetables.”

The cube uses hydroponics to grow plants without soil. Software controls the environment, so seedlings get the correct amount of air, light and water as they develop. A fan directs the air flow. The built-in lights are LEDs. Red lights promote the growth of the seedlings, while white light supports established plants.

Jack Ting adds: “All water is UV light purified, so it is very safe, even our vegetables, no need to wash.”

With an app that connects your smartphone or computer to the cube, you can monitor the process, or make your own adjustments to the air temperature, humidity and light settings.

For garden centers and commercial farmers, OPCOM has created a larger system called the farm container. Using solar power, this multi-cube can grow 2,000 plants at a time. (Deborah Block, VOA News, Washington)

Blue Light From Smartphones Accelerates Blindness

Blue light introduced to other cell types in the body, such as cancer cells, heart cells and neurons, they died as a result of the combination with retinal. Blue light alone or retinal without blue light had no effect on cells.

Are you addicted to your smartphones, laptops and tablets? The blue light emitting from these digital devices can affect your eye’s retina and lead to age-related macular degeneration, according to a research led by a professor of Indian-origin.

Macular degeneration, an incurable eye disease that results in significant vision loss starting on average in a person in his 50s or 60s, is the death of photoreceptor cells in the retina. Those cells need molecules called retinal to sense light and trigger a cascade of signalling to the brain.

The findings showed that blue light exposure causes retinal to trigger reactions that generate poisonous chemical molecules in photoreceptor cells.

“We are being exposed to blue light continuously, and the eye’s cornea and lens cannot block or reflect it,” said Ajith Karunarathne, Assistant Professor, University of Toledo in Ohio, US.

“It’s no secret that blue light harms our vision by damaging the eye’s retina,” he added.

Since photoreceptors, produced in the eye, are useless without retinal, one needs a continuous supply of retinal molecules to see.

“It’s toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signalling molecule on the membrane dissolves,” explained Kasun Ratnayake, doctoral student researcher at the varsity.

“Photoreceptor cells do not regenerate in the eye. When they’re dead, they’re dead for good.”

In the study, published in the journal Scientific Reports, when the team introduced blue light to other cell types in the body, such as cancer cells, heart cells and neurons, they died as a result of the combination with retinal. Blue light alone or retinal without blue light had no effect on cells.

“The retinal-generated toxicity by blue light is universal. It can kill any cell type,” Karunarathne said.

To protect your eyes from the blue light, wear sunglasses that can filter both UV and blue light outside and avoid looking at your cell phones or tablets in the dark, he suggested. (IANS)
