Photosynthesis is one of the most important chemical reactions, not just for plants but also for the entire world.
Michigan State University researchers and colleagues at the University of California Berkeley, the University of South Bohemia and Lawrence Berkeley National Laboratory have helped reveal the most detailed picture to date of important biological “antennae.”
A new study on rubisco, a photosynthetic enzyme thought to be the most abundant protein on the planet, shows that proteins can change their structural arrangement with surprising ease. The findings reveal the possibility that many of the proteins we thought we knew actually exist in other, unknown shapes.
Researchers have developed floating ‘artificial leaves’ that generate clean fuels from sunlight and water, and could eventually operate on a large scale at sea.

Every plant, animal or other nucleus-containing cell also harbors an array of miniature “organs” that perform essential functions for the cell.
A Rutgers-led study sheds new light on the evolution of photosynthesis in plants and algae, which could help to improve crop production.
New research from West Virginia University biologists shows that trees around the world are consuming more carbon dioxide than previously reported, making forests even more important in regulating the Earth’s atmosphere and forever shift how we think about climate change.
A nuclear war could trigger an unprecedented El Niño-like warming episode in the equatorial Pacific Ocean, slashing algal populations by 40 percent and likely lowering the fish catch, according to a Rutgers-led study. The research, published in the journal Communications Earth & Environment, shows that turning to the oceans for food if land-based farming fails after a nuclear war is unlikely to be a successful strategy – at least in the equatorial Pacific.
Postdoctoral scholar Katharyn Duffy led an international team that looked at 20 years of data from throughout the world and found that record-breaking temperates are contributing to a significant decrease in plants’ ability to absorb human-caused carbon emissions.
Red algae have persisted in hot springs and surrounding rocks for about 1 billion years. Now, a Rutgers-led team will investigate why these single-celled extremists have thrived in harsh environments – research that could benefit environmental cleanups and the production of biofuels and other products.
Cornell University scientists have engineered a key plant enzyme and introduced it in Escherichia coli bacteria in order to create an optimal experimental environment for studying how to speed up photosynthesis, a holy grail for improving crop yields.
How much carbon dioxide, a pivotal greenhouse gas behind global warming, is absorbed by plants on land? It’s a deceptively complicated question, so a Rutgers-led group of scientists recommends combining two cutting-edge tools to help answer the crucial climate change-related question.
Recently, scientists have achieved record efficiency for solar-to-fuel conversion, and now they want to incorporate the machinery of photosynthesis to push it further. They present their results today at the American Chemical Society Fall 2020 Virtual Meeting & Expo.
The new discovery unveils the molecular machinery that plants use to weave cellulose chains into cable-like structures called “microfibrils.”
A new Columbia Engineering study demonstrates that even when temperatures warm and cold stress is limited, light is still a major factor in limiting carbon uptake of northern high latitudes. The team analyzed satellite observations, field measurements, and model simulations and showed that there is a prevalent radiation limitation on carbon uptake in northern ecosystems, especially in autumn.
Using a unique combination of nanoscale imaging and chemical analysis, an international team of researchers has revealed a key step in the molecular mechanism behind the water splitting reaction of photosynthesis, a finding that could help inform the design of renewable energy technology.
Researchers zeroed in on a key step in photosynthesis in which a water molecule moves in to bridge manganese and calcium atoms in the catalytic complex that splits water to produce breathable oxygen. What they learned brings them one step closer to obtaining a complete picture of this natural process, which could inform the next generation of artificial photosynthetic systems that produce clean and renewable energy from sunlight and water. Their results were published in the Proceedings of the National Academy of Sciences today.
Algae in the oceans often steal genes from bacteria to gain beneficial attributes, such as the ability to tolerate stressful environments or break down carbohydrates for food, according to a Rutgers co-authored study.
The study of 23 species of brown and golden-brown algae, published in the journal Science Advances, shows for the first time that gene acquisition had a significant impact on the evolution of a massive and ancient group of algae and protists (mostly one-celled organisms including protozoa) that help form the base of oceanic food webs.
A new Columbia Engineering study shows that increased water stress—higher frequency of drought due to higher temperatures, is going to constrain the phenological cycle: in effect, by shutting down photosynthesis, it will generate a lower carbon uptake at the end of the season, thus contributing to increased global warming.
The U.S. Department of Energy (DOE) announced a plan to provide up to $100 million over five years for research on artificial photosynthesis for the production of fuels from sunlight.
Scientists solved a critical part of the mystery of photosynthesis, focusing on the initial, ultrafast events through which photosynthetic proteins capture light and use it to initiate a series of electron transfer reactions.
Think of a train coming down the tracks to a switch point where it could go either to the right or the left — and it always goes to the right. Photosynthetic organisms have a similar switch point. New research from Washington University in St. Louis and Argonne National Laboratory coaxes electrons down the track that they typically don’t travel
You’d think that losing 25 percent of your genes would be a big problem for survival. But not for red algae, including the seaweed used to wrap sushi. An ancestor of red algae lost about a quarter of its genes roughly one billion years ago, but the algae still became dominant in near-shore coastal areas around the world, according to Rutgers University–New Brunswick Professor Debashish Bhattacharya, who co-authored a study in the journal Nature Communications.
Scientists have discovered how diatoms – a type of algae that produces 20 percent of the Earth’s oxygen – absorb solar energy for photosynthesis. The Rutgers University-led discovery, published in the journal Proceedings of the National Academy of Sciences, could help lead to more efficient and affordable algae-based biofuels and combat climate change from fossil fuel burning.
