Micro-naps for plants: Flicking the lights on and off can save energy without hurting indoor agriculture harvests

Indoor plant factories have high energy costs since LEDs replace the sunlight outdoor plants get for free. Scientists found a way to dial back how much light is needed by breaking it into tiny bursts.
The short answer is that leaves fall off trees when they aren’t doing their job any more. Emily Nunell/The Conversation CC-NY-BD

Leaves fall off trees when they aren’t doing their job any more. If there isn’t enough water, the leaf can be damaged and stop working.
Though not this obvious from the outside, plants are keeping time. Hua Lu

Studying circadian rhythms in plants and their pathogens might lead to precision medicine for people

Precisely calibrated timekeepers are found in organisms from all domains of life. Biologists are studying how they influence plant/pathogen interactions – what they learn could lead to human medicines.
Ferns are a very old group of plants that came along more than 200 million years before the dinosaurs walked the earth. Marcella Cheng/The Conversation

Curious Kids: Why are fern leaves shaped the way they are, and are all ferns identical?

Ferns came along more than 200 million years before the dinosaurs walked the Earth. They were food for plant-eating dinosaurs and they’re really great survivors. Heather, age 8, wants to know more.
Cassava feeds 800 million people - keeping it disease-free is a must.

World hunger: what the Ebola virus can teach us about saving crops

Rapid genetic disease screening will be the key to saving East Africa’s crops - just as it was during West Africa’s ebola crisis.

Taking plants off planet – how do they grow in zero gravity?

Plants on the International Space Station must figure out how to grow in a completely novel environment. Their adaptability hints at how they’ll react to changes here on Earth – or in future space outposts.

Despite the lush summer leaves, our trees are under attack

Looking at the countryside now in the middle of summer, it is hard to believe that trees are under threat from an array of diseases and pests. Warm and wet conditions with plenty of sunshine have led to…
