Next Generation: Nanoparticles Augment Plant Functions
The incorporation of synthetic nanoparticles into plants can enhance photosynthesis and transform leaves into biochemical sensors.
The technique: Researchers have boosted the photosynthetic activity of plants by delivering carbon nanotubes into chloroplasts, the plant-cell organelles that house the molecular machinery that converts solar energy into sugars.  
A team led by Michael Strano, a chemical engineer at MIT, showed that single-walled carbon nanotubes (SWNTs) coated with single-stranded DNA infiltrate the lipid envelope of extracted plant chloroplasts and assemble alongside photosynthetic proteins. The same thing happened when the SWNTs were delivered into living Arabidopsis thaliana leaves through microscopic pores known as stomata.

Krzysztof Pruszkowsi - Doloreze Echassse
Initially trained as an architect, Polish-born Krzysztof Pruszkowski took up photography after moving to Paris in 1965. He did fashion, publicity and documentary work for several years before feeling the constraints of what he perceived as the expressive limitations of single images. He subsequently devised a method of extreme multiple-image creation beginning in 1975 called Photosynthesis. Inspired in part by Jacques Derrida’s concept of drawing numerous interpretations from a single text, the dense visual layering of Pruszkowski’s images is mirrored by their kaleidoscopic allusions to all manner of philosophical, cultural, sexual and political issues. His recent projects include a look at media representations of terrorists and their victims, as well as a series focused on myths of the 20th century.

Quantum mechanics explains efficiency of photosynthesis
Light-gathering macromolecules in plant cells transfer energy by taking advantage of molecular vibrations whose physical descriptions have no equivalents in classical physics, according to the first unambiguous theoretical evidence of quantum effects in photosynthesis published today in the journal Nature Communications.
The majority of light-gathering macromolecules are composed of chromophores (responsible for the colour of molecules) attached to proteins, which carry out the first step of photosynthesis, capturing sunlight and transferring the associated energy highly efficiently. Previous experiments suggest that energy is transferred in a wave-like manner, exploiting quantum phenomena, but crucially, a non-classical explanation could not be conclusively proved as the phenomena identified could equally be described using classical physics.
Often, to observe or exploit quantum mechanical phenomena systems need to be cooled to very low temperatures. This however does not seem to be the case in some biological systems, which display quantum properties even at ambient temperatures.
Now, a team at UCL have attempted to identify features in these biological systems which can only be predicted by quantum physics, and for which no classical analogues exist.

'Solar-powered' sea slugs can survive in the dark
They’ve been called ‘solar-powered slugs’ and ‘leaves that crawl’ — species of sacoglossan sea slug that assimilate the photosynthetic organelles in the algae they eat, causing their bodies to turn bright green. But it turns out that these slugs can survive months of starvation even when their photosynthetic capacity is massively reduced, casting doubt on the widely-accepted theory that they rely on photosynthesis to feed themselves when there’s nothing around to eat.

The sea slug Elysia timida extracts the photosynthesizing organelles from single-cell algae it feeds on — but it is unclear whether it actually can use them as its personal solar panel. Sven Gould/Jan de Vries

Cooling Towers

Take 300,000 computer-controlled mirrors, each 7 feet high and 10 feet wide. Control them with computers to focus the Sun’s light to the top of 459-foot towers, where water is turned into steam to power turbines. Bingo: you have the world’s biggest solar power plant, the Ivanpah Solar Electric Generating System.
