Cyanobacteria filled the ancient oceans and used chlorophyll to harvest the sun’s energy.
Did you recently hear news that Earth's oldest pigments were hot pink? That's not quite right. When they were in living bacteria a billion years ago, they were performing photosynthesis – and green.
Understanding how certain proteins deal with light absorption can inspire modern solar technology.
Proteins guard their secrets closely, but once you get them to "sing", there's an enormous amount to learn.
Genetically engineered tobacco plants growing in a greenhouse.
As the climate changes and the population grows, meeting the demand for food will become more difficult as arable land declines. But an international team of scientists has figured out an innovative solution to dramatically bumping up crop yields.
Long’s Peak framed by rock outcrop, Rocky Mountain National Park, Colorado.
Scientists have long thought most nitrogen in Earth's ecosystems comes from the air, but new research shows it also is released as rocks weather. This could boost plant growth and help sequester carbon – but not fast enough to avert climate change, as some pundits have claimed.
New research finds more CO₂ can actually make most plants smaller in the long-term - but the story for crops isn't so simple.
The leaves of most plants are green because the leaves are full of green chemicals.

Diatoms - like those seen under a microscope here - can teach us a lot about harvesting light.
Diatoms' tricks may offer new insights that keep solar cell energy running efficiently and robustly throughout their processes.
“Snowball Earth” happened around 700 million years ago.
Earth's thermostat can fail spectacularly at times. Around 700 million years ago, huge volcanic eruptions triggered "Snowball Earth".
Once the coat around the seed is moistened, the embryo cells expand and burst out in a process called germination.
A seed contains nearly everything a tree needs to get growing. Just add a dash of water, a bit of warmth and the right location, and you'll be seeing green in no time.
If harnessed properly, the sun holds tremendous potential to provide sustainable energy for the earth.
Cassava makes up nearly 50 percent of the diet in parts of sub-Saharan Africa, where populations are projected to increase by more than 120 percent in the next 30 years.

Cassava is a key food source in tropical countries, but yields have been flat for decades. New genetic research is identifying many options for boosting production of this valuable staple crop.
Photosynthesis can teach scientists a lot about solar technologies.
Individual light-harvesting protein complexes have a remarkable ability. Light, which is normally effectively harvested, is also used to finely control how much of it should be harvested.
Green planet: tropical rainforests have produced more growth in response to rising carbon dioxide.

Half of the world's vegetated land has got greener in the past 30 years, mostly driven by rising CO2.
You know what, I think we looked better before.
There are solar-power sea slugs, so why haven't humans mastered the art of photosynthesis?
Photosynthesis is crucial to the ability of plants to convert sunlight into energy.

Distinguished Professor Graham Farquhar has received this year's Prime Minister's Prize for Science for his pioneering research into photosynthesis.
Observations from space have shown the world overall is getting greener despite deforestation and drought.
A new investigation of satellite records reveals that the Earth is getting greener, despite ongoing deforestation in Indonesia and South America.
Blooming marvellous: cacti are among the few plant species that can thrive in the desert.
Photosynthesis can be costly - but plants in hot and dry environments have evolved two special strategies for storing carbon dioxide, that could be used to protect crops against climate change.
Plants use photosynthesis to build molecules and energy they can use. By copying plants, humans can make cleaner fuels.
Most of the energy that fuels our lives comes from plants. Whether it is a fossil fuel that was formed hundreds of millions of years ago or the food we eat, all carbon-borne energy has its ultimate origins…
Enjoy the color while you can before climate change makes a mess of this too.
One of nature’s most spectacular events occurs every autumn, when the leaves of hardwood trees burst into brilliant color before falling to the ground. These autumnal displays in the eastern United States…
