Artificial Synthesis Of Starch From CO2

Scientists in China have developed a method of artificial synthesis of starch from CO2 which is more efficient than natural plant photosynthesis. The hope is to free up 90 percent of cultivated land and freshwater resources by producing starch directly from CO2.

Colours Of The Sky

#283

Did you know that the sky is blue because of Rayleigh scattering? Did you know that the horizon is lighter because of Mie scattering? If not, check out this great article by Daniel Brown about the different colours of the sky.

Glow In The Dark Plants

#282

Scientists at MIT have successfully injected nanoparticles into plants to give them glow in the dark properties, for the second time. The strontium aluminate nanoparticles are coated in silica so as not to damage the plant. Just 10 seconds of exposure to LED or sunlight cause the plants to glow green for up to an hour, at a brightness ten times more than the previous experiment. The plan is to be able to use these glowing plants as passive lighting in outdoor areas, thus reducing the need for street lighting.

Russia Wants To Clone A 3000 Year Old Army

#275

The Russian Defence Minister wants to extract the DNA from the archealogical remains of Scythian warriors (9th to 2nd century BC) found in Siberia and use it clone an army of warriors. You would be forgiven in thinking this was the plot of a movie blockbuster but no, it was a conversation held during an online session of the Russian Geological Society last month.

Our Eyes Can't Focus On Blue

#275

Due to the differing focal points of coloured light, our eyes can't focus on blue as well as green and red light at the same time. As a result, our brain steps in and makes up the difference. Check out Caleb Kruse interesting post that illustrates this with some side by side comparisons of images with and without the blue channel.
