Chemicals found in vegetables prevent colon cancer in mice. “Chemicals produced by vegetables such as kale, cabbage and broccoli could help to maintain a healthy gut and prevent colon cancer, a new study shows.” (The Francis Crick Institute via sciencedaily.com) https://bit.ly/2QnsVNV

When the seed becomes a plant, it has 48 hours to survive. “When a seed germinates, it only has two days to turn into a seedling capable of photosynthesis, before having exhausted its reserves. In a new study, researchers reveal the underlying mechanism of this process.” (University of Geneva via sciencedaily.com) https://bit.ly/2oXrCZo
The rewards of chasing nectar. “We know that flowers entice pollinators with nectar, but how much and what causes a flower to produce as much or as little nectar as it does.” (Amy Parachnowitsch, Jessamyn Manson & Nina Sletvold via Botanyone) https://bit.ly/2x7B1Bw

Bringing houseplants back indoors. “Many houseplants thrive during the long, bright summer days, especially when properly moved outdoors. But these plants may have some trouble adjusting back to indoor conditions when colder weather strikes.” (Rosie Lerner, Purdue Extension) https://bit.ly/2x7s5gd

The Poison Gardens of Alnwick Garden– behind a locked gate, there’s the Poison Garden: it contains only poisonous plants. Watch the video tour. (Tom Scott, youtube.com) https://bit.ly/2QnMsh3
Rhododendron? Hydrangea? America Doesn’t Know Anymore. “The country has a growing case of ‘plant blindness’—a term used by botanists to describe the inability to identify basic plants. Even biologists struggle.”(Douglas Belkin, wsj.com) https://on.wsj.com/2nLv1u3
Save your vegetable seeds for next years’ planting. “You can save vegetable seeds from your garden produce to plant next year. Seed saving involves selecting suitable plants from which to save seed, harvesting seeds at the right time and storing them properly over the winter.” (University of Minnesota Extension) https://bit.ly/2N58ash

How eggplants became Asian: Genomes and elephants tell the story. “The evolutionary context of the eggplant was until recently very poorly known. Historical documents and genetic data have shown that the eggplant was first domesticated in Asia, but most of its wild relatives are from Africa.”(University of Helsinki, via sciencedaily.com) https://bit.ly/2QkszYm

New process in root development discovered. Scientists uncover communication at the root tip. “As the plant root grows, a root cap protects its fragile tip. Every few hours, the old cap is lost and a new one replaces it. Researchers have now, for the first time, observed regular cycles of root tip loss and regrowth in real time. In doing so, they uncovered the signal and receptor that coordinate this process.” (Institute of Science and Technology, via sciencedaily.com) https://bit.ly/2xbw8ID

Why Victorian gardeners loathed magenta. “For decades, British and American gardeners avoided magenta flowers. The color had associations with the unnatural and the poisonous.” (Allison Meier, Sciencedaily.com) https://bit.ly/2MUmQdC
The bark side of the force “-What forces enable trees to stand upright? To grow straight, plants need a motor system that controls their posture by generating forces to offset gravity. Scientists have long thought that this motor force was controlled only by the internal forces induced in wood. In a new study, scientists show that bark is also involved in the generation of mechanical stresses in several tree species.” (CNRS, via sciencedaily.com) https://bit.ly/2ASZsaT
When roots crack and worms crunch. “Roots can be “listened to” while growing – and worms when burrowing. Researchers … present a new method for soil analysis.” (Michael Walther, ETH Zurich, via phys.org) https://bit.ly/2MixFkI
