Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.
- Climate
Some tree leaves are finding it too hot for photosynthesis
Earth’s ongoing fever threatens to push entire forests toward this heat limit — and possible death.
- Life
Scientists Say: Mycelium
These fibrous networks are the reason plants think fungi are such "fun guys.”
- Tech
High-tech solar ‘leaves’ create green fuels from the sun
Chemists make a liquid alternative to fossil fuels from carbon dioxide, water and the sun. Their trick? They use a new type of artificial leaf.
- Planets
Research on exoplanets took top award at 2023 Regeneron ISEF
Six young researchers took home the top awards, each valued at a minimum of $50,000. Hundreds more shared nearly $9 million in prizes at international event.
- Agriculture
Native Amazonians make rich soils — and ancient people may have too
Modern Amazonians make nutrient-rich soil from ash, food scraps and burns. The soil strongly resembles ancient “dark earth” found in the region.
- Chemistry
Scientists Say: Rubisco
Rubisco is a key protein in the process of photosynthesis, which feeds plants — and, in turn, us.
- Chemistry
No sun? No prob! A new process might soon grow plants in the dark
Teamwork makes green-work! Collaborating scientists came up with an electrifying farming trick that could make sunlight optional.
- Ecosystems
Some redwood leaves make food while others drink water
The two types of leaves grow at different heights in trees at dry versus wet areas. They may help redwoods adapt to climate change.
- Life
In blazing heat, some plants open leaf pores — and risk death
When heat waves and droughts collide, water is precious. Some thirsty plants try to cool off by opening tiny pores — only to lose water even faster.
- Microbes
Genes point to how some bacteria can gobble up electricity
A new study shows how some microbes absorb and release electrons — a trait that may point to new fuels or ways to store energy.
- Plants
Scientists Say: Phloem
Phloem is tissue that delivers food, made in leaves during photosynthesis, to the rest of a plant.
- Tech
Synthetic trees could tap underground water in arid areas
They also could also help coastal residents mine fresh water from salty sources.
