Kudzu, or Japanese arrowroot, is an invasive vine that climbs and encases anything it encounters, including native vegetation like these trees in Mississippi. It’s sometimes called ‘the vine that ate the South.’

Scientists want to understand behaviour of invasive weeds

Why are certain plants able to enter a new ecosystem and run riot?

By
Is it possible to predict which non-native plant species will become invasive weeds and when? According to research featured in the journal Invasive Plant Science and Management, the answer is “hopefully yes.” Researchers say invasive species generally follow a three-phase development curve — from lag to expansion to plateau. The length and rapidity of the
Flowering plants are the largest, most important and newest type of plants.

How flowers won

Flowering plants conquered the world, 
now scientists think they know why

By
It’s a problem that puzzled even geneticist Charles Darwin so much he called it the “abominable mystery” — how did flowering plants take over the world? They’re relative newcomers, yet they dominate most landscapes, are incredibly diverse, form the basis of our food system and drive the animal diversity we see all around us. A

A row to hoe

Robots are the future of weed control, one researcher says

By
Forget about that old hoe — it’s time to go high tech with weed control. Researchers at the University of California-Davis say robotic weeders are already making headway in high-value vegetable crops, fuelled by a lack of chemical controls and lack of affordable labour. Steven Fennimore, an extension specialist at the university, pegs the cost

No rest for weary canola plants

You’re not the only one who can’t get any ‘sleep’ during those sweltering summer nights

By
Turns out your canola plants just need to get a little rest. When high temperatures, especially at night, prevent them from “sleeping” properly productivity takes a hit, and now researchers from Kansas State University are trying to figure out why. What exactly is the plant doing at night? It’s not sleeping like humans do, but

Nitrogen reduction not the path

Reducing how much nitrogen enters a lake has little impact on algal blooms, IISD researchers say

By
If you take the nitrogen out of the equation for lake algal blooms it turns out you really haven’t changed things at all. According to researchers at the Experimental Lakes Area, operated by Winnipeg’s International Institute for Sustainable Development, that’s because many of the algae responsible for the harmful blooms can turn around and fix
Rescued Relish is an anything-goes condiment made from excess produce that Philabundance, a Philadelphia anti-hunger organization, can’t move. 
The relish is modelled on a Pennsylvania Dutch chow chow recipe — a tangy mix of sweet, spicy and sour flavours.

Eating garbage

A new study shows acceptance, and even preference for, 
food made from waste

By
A recent study has shown consumers won’t just accept food made from discarded ingredients — they’ll embrace it. Researchers from Philadel­phia’s Drexel Univer­sity looked at products that were made from recovered ingredients that would otherwise have been destined for the waste stream. “There is an economic, environmental and cultural argument for keeping food, when possible,
Plants crave light and even grow towards it. Now researchers understand how they do that.

Shine a light on plant growth

Researchers have discovered how plants respond to changes in light 
at the molecular level

By
Plants don’t have eyes, but it would seem they do “see” their surroundings using light. That’s made possible by proteins called photoreceptors that absorb light and convert it into a signal that turns genes on or off. Until now, scientists haven’t fully understood the molecular mechanism underlying that process, which allows plants to recognize when
Lake Winnipeg algae blooms can create, under certain conditions, powerful neurotoxins.

Lake Winnipeg blooms create neurotoxins

Researchers say the substances have been associated with 
several health conditions

By
Manitoba’s largest lake is the host to potentially harmful toxins caused by cyanobacteria, more commonly known as “blue-green algae.” Researchers from the University of British Columbia, working with the Lake Winnipeg Research Consortium, were looking for a specific toxin called BMAA that’s been linked with conditions ranging from Alzheimer’s to Lou Gehrig’s disease. “Cyanobacteria blooms

Spare the bees

New research may make for better-targeted pesticides that do their job but don’t hurt beneficial insects

By
Pyrethroid pesticides could be modified with a few molecular tweaks to eliminate pests while preserving beneficial insects like bees. Those are the findings of researchers at Michigan State University’s entomology department in a study featured in the current issue of Proceedings of the National Academy of Sciences. These pesticides target a protein known as the

Researchers break the wild-domestic barrier in legumes

They’re hoping to tap wild relatives for important traits 
such as disease and pest resistance

By
Domesticating plants to grow as crops can turn out to be a double-edged scythe. On one hand, selecting specific desirable traits, such as high yields, can increase crop productivity. But other important traits, such as resistance to pests, can be lost. To mitigate this, researchers often turn to the wild relatives of crops. These wild
