Heat reduces photosynthesis in California redwoods
California redwoods reduce photosynthesis at high temperatures, which may affect their long-term survival and forests’ capacity to store atmospheric carbon.
California redwoods are struggling in the heat — and it's not clear how much damage is being done
When temperatures rise, California redwoods slow down their rate of photosynthesis, a discovery that could have implications for the long-term survival of the iconic species.
When climate change brings the heat, what happens to a mighty redwood?
In heat wave-like temperatures, coast redwoods' photosynthesis slows down, which may put one of Earth's most efficient carbon storers in jeopardy.
Scientists finally see how nature moves energy so efficiently
Researchers have captured key steps in a chemical reaction that helps nature transfer energy with remarkable efficiency. Ultrafast X-rays revealed how changes involving electrons and protons are closely linked to the rearrangement of surrounding water molecules. Because similar reactions drive photosynthesis and other energy-conversion processes, the technique could help scientists develop better catalysts, fuel cells, and flow batteries.
Scientists capture first molecular-level images of water reorganization during a reaction crucial for life
Some of nature's most important chemical reactions rely on the coupled movement of negatively and positively charged particles. These processes play central roles in photosynthesis, catalysis and biological ...
Cell-inspired nanoreactor turns sunlight into hydrogen peroxide
A new hollow nanoreactor mimics living cells to make hydrogen peroxide more efficiently using visible light. Its light-trapping cavity and proton-shuttling shell could open new possibilities for cleaner chemical manufacturing and artificial photosynthesis.
Rudolph Marcus, Who Illuminated Electrochemical Processes, Dies at 102
He received a 1992 Nobel Prize for developing a theory that explained fundamental processes behind photosynthesis, respiration, oxidation and even how fireflies produce light.
University of Chicago scientists create "artificial leaf" that could be used for wireless implants
What University of Chicago scientists call an artificial leaf that mimics photosynthesis could be useful for wireless medical implants and other technologies.
Trees keep absorbing carbon long after they stop growing
Oak trees keep absorbing carbon dioxide long after their annual growth has ended, revealing that photosynthesis and wood production are not as closely linked as scientists once believed. The finding could reshape forecasts of how much carbon forests will be able to store in a warmer future.
Scientists built a battery-free device that turns sunlight into fuel
Scientists have developed an artificial photosynthesis system that essentially regulates itself, eliminating the need for batteries used in many current designs. The key innovation is an electrolyzer that automatically adapts to changing sunlight by altering its electrical properties as it heats up. This keeps solar fuel production more stable while reducing cost and complexity.
Scientists got mouse eyes to perform photosynthesis — and no, they didn't turn green
Special eye drops containing photosynthetic machinery from spinach leaves have helped combat dry eye, a new mouse experiment reveals.
Where scientists watch the forest breathe, findings uproot how people think about forest-atmosphere interactions
Photosynthesis is the oldest carbon-capture technology on Earth. For eons, plants have pulled carbon dioxide from the atmosphere and locked carbon—the building block of life on our planet—into their bodies ...
Schematic Diagram of Semiartificial Photosynthesis
A semiartificial photosynthesis system composed of photocatalysts (purple), electron mediators (red), and biocatalysts (green) works together to convert carbon dioxide into useful substances using sunlight.
Scientists discover tiny plant trick that could supercharge crop yields
Researchers have uncovered a molecular trick used by hornwort plants that could help future crops capture carbon dioxide more efficiently. A unique protein feature called RbcS-STAR causes the key photosynthesis enzyme Rubisco to cluster into dense compartments, helping it work more effectively. When scientists added this feature to other plants, Rubisco reorganized in the same way. The finding raises the possibility of engineering more efficient photosynthesis into major crops.
This “mushroom” is not a fungus, it’s a bizarre plant that breaks all the rules
Balanophora is a plant that abandoned photosynthesis long ago and now lives entirely as a parasite on tree roots, hidden in dark forest undergrowth. Scientists surveying rare populations across East Asian islands uncovered how its cellular machinery shrank but didn’t disappear, revealing unexpected similarities to parasites like malaria. Some island species even reproduce without sex, cloning themselves to colonize new habitats. This strange survival strategy comes with risks, leaving the plant highly vulnerable to habitat loss.
Researchers turned a hamster into a hybrid creature that feeds on light—half animal, half plant - Futura-Sciences
A team from the University of Tokyo has achieved a breakthrough that sounds straight out of science fiction: they’ve created living cells that are part hamster, part plant — and capable of performing photosynthesis. Imagine ... Read more
