Will glowing trees replace street lamps in the near future? Can glowing plants be used as a source of light?
These questions have occupied a group of scientists who have come up with an ingenious idea how to cut electricity costs and reduce light pollution.
Walking down the street a late evening you might actually find yourself surrounded by amazingly beautiful glowing trees and pants, instead of ordinary street lamps.
Researchers say that after proper optimization, threes and plants can be used to construct biological street lightning and serve as an efficient energy source.
Glowing plants can soon be used as a source of light.
A group of researchers in Taiwan led by Yen Hsun Su and colleagues at Academia Sinica in Taipei and the National Cheng Kung University in Taiwan
have successfully synthesized gold nanoparticles and implemented them into leaves of Bacopa caroliniana plant to induce bioluminescence in them.
This process turned the leaves into bio-light-emitting diodes.
Nanoparticles are particles with a diameter of about 10 nanometers ( a nanometer is a billionth of a meter).
Bacopa caroliania is a perennial aquatic or semi-aquatic herb commonly used as aquarium plant."
The color of the leaves varies in proportion to the amount of light, turning bronze to almost red when exposed to high light levels."
"The green pigment in leaves, chlorophyll, is bioluminescent when exposed to high wavelength (400 nanometers (nm)) ultra violet excitation,
but the wavelength is much shorter for the photoluminescence of gold nanoparticles, and they emit light at 400 nm.
The light is localized at a nanoscale and the nanoparticles made by the Taiwan team suppresses emission blinking, which is a problem already
known in gold nanoparticles. Using their sea-urchin-shaped nanoparticles (dubbed nano-sea-urchins or NSUs), Su was able to excite chlorophyll in
the leaves to emit red light."
You may soon be surrounded by glowing trees instead of ordinary street lamps.
During the experiments scientists also discovered a relationship between the size of the gold particle and the intensity of the bioluminescence.
The larger particle, the more the leaf was shining.
Yen Hsun Su and his colleagues are now trying to apply the same technique to other plant molecules.
They are also determined to improve the efficiency of the process.
Although the idea of using plants as sources of light may appear to be pure science fiction, Su and his team have successfully proved the idea is based on
science and not fiction.
Su believes that bio-light-emitting diodes might eventually be used to make trees lining roads luminescent at night.
Since the light causes the chloroplast to conduct photosynthesis no energy source is needed and the plant will absorb CO2 for the process,
which does not normally occur at night.
Plants and trees which posses the ability to glow in the dark may provide us with new energy sources in the near future.
Abnormal Star Discovered In The 'Forbidden Zone'
A team of astrophysicists from Germany, France and Italy have discovered in the constellation Leo is an old star.
The star's existence raised at once many questions for scientists.
The object is definitely not as its "contemporaries" that appeared immediately after the Big Bang event.
Astrophysicist Resolves Paradox With Radio Millisecond Pulsars
Celestial objects known as pulsars are still full of secrets. It is takes time and many efforts to learn all their secrets. Previous studies reached
the paradoxical conclusion that some millisecond pulsars are even older than the universe itself. It was time to resolve this paradox.
The Eyes Of A Future Alien Astronomer - What Will They See?
Have you ever wondered what the Universe will look like for a future alien astronomer?
It will in fact be entirely different from what it is today.
One trillion years from now, an alien astronomer in our galaxy will have great difficulties figuring out how the universe began.
The Milky Way will have merged with the Andromeda galaxy to form the Milkomeda galaxy. Many of its stars, including our Sun, will have burned out.
Violent Dragon Clash Billions Of Years Ago
NGC 5907 is sometimes called the "Splinter" or Knife Edge Galaxy because of its unusual appearance.
It is a spiral galaxy lying in the Dragon constellation,
about 40 million light-years from Earth that could have been formed through a gigantic collision of galaxies, 8 to 9 billion years ago.
"Sacred" 1.7 Million Volt Light Of The Gods
Today, his cool experiment enables Zeus-like miracles!
For the ancient Greeks, the occurrence of lightning mean that Zeus, lord of heaven,
was often very angry and upset. God used to throw jagged, terrifying bolts of lightning, like spears of fire. This was for the ancients, a "sacred light".
In his lab near Chicago, Illinois, a retired electrical engineer, Bert Hickman, uses a particle accelerator acrylic plastic to "grab and keep the wrath of Zeus"...
Our Universe Is A Gigantic And
Wonderfully Detailed Holographic Illusion
In our daily life we are not aware that we may, in fact, live in a hologram and our existence is a holographic projection, nothing more.
All what we believe is real, our whole physical world, is - in fact - an illusion being proved by the holographic universe,
one of the most remarkable theories of 20th century...
