Machine learning may enable bioengineering of the most abundant enzyme on the planet

A Newcastle University study has developed a machine learning tool that can predict the performance properties of land plant Rubisco proteins with high accuracy. This prediction will enable researchers to identify and engineer 'supercharged' Rubisco proteins that can increase atmospheric CO2 uptake and store in crops such as wheat.

Discovery uncovers a new leaf for redwoods

Researchers discovered that redwood trees have two functionally distinct leaves: one type specializes in converting sunlight into sugar through photosynthesis, while the other absorbs water. This adaptation allows the world's tallest trees to survive in a range of conditions, from wet forests to dry environments.

Smithsonian study finds more ‘losers’ than ‘winners’ among plants in the age of humans

A new analysis by Smithsonian researchers categorized over 86,000 plant species as winners or losers according to their ability to survive in the age of humans. The study found that more than 20,000 plant species are at risk of extinction due to human activities, with many species deemed 'losers' rather than 'winners',

Humidity changes in dead fern fronds drives unique timing of spore dispersal in a widespread fern species

Researchers discovered that humidity-driven movement in spore-bearing leaves is the key mechanism behind the unique timing of spore dispersal in the sensitive fern. The study found that dead fronds open when dry and close when wet due to differential cell expansion, a process also observed in pine cones.

Planting new forests with high functional diversity helps improve productivity

A study by Prof. MA Keping and colleagues found that older forests with high functional diversity achieve higher productivity than those with low diversity or specific high average traits. This reliable tool helps forest managers connect restoration actions to goals, essential for mitigating climate change and biodiversity loss.
