Could you explain "No word yet on any subsequent increase in actual sugar production."? Marked ◆◆◆ M.I.T. researchers say that plants are a great technology platform: they can survive harsh weather and they are their own energy factories. So the team turned to improving plants’ capabilities. They inserted carbon nanotubes into the plants’ chloroplasts, the site of photosynthesis. The tubes capture wavelengths of light that plants usually don’t absorb, such as ultraviolet and green. Living plants with nanotube-enhanced chloroplasts showed a 30 percent increase in electron flow, a key aspect of photosynthesis. ◆◆◆No word yet on any subsequent increase in actual sugar production.◆◆◆ The researchers turned plants into sensors by embedding carbon nanotubes that were engineered to fluoresce in response to nitric oxide, a pollutant from combustion. They’ve also created nanotubes that can detect chemicals including TNT and the nerve gas sarin. Pollution, pesticides and explosives could someday be monitored via bionic botanicals.
