Issue #5 of Philly-based sustainability magazine Grid arrived this week—chock full of summertime “how to” cheer that’s just begging to be shared. Grid is a free magazine, and you can read its entire digitized issue online. Be sure to check out:

How to make rhubarb cobbler on page 15: This tasty-looking recipe calls for delectable maple sugar instead of the loads of predictable, refined white sugar found in most rhubarb concoctions.

How to attract beneficial insects to your garden on page 12: From lacewings to ladybugs, Grid has the skinny on how to lure the good guys—insects that pollinate and keep pest populations in check—into your yard, including specific “companion plants.”

Plus: How to fix a flat bike tire (page 10), how to recycle your television (page 11), and loads of other recipes, including vegan blood orange cupcakes and sugar-snap peas with bacon.

Scientists believe this discovery could hold the answer to how honeybee, ant and other “ultrasocial creature” queens keep their kingdoms in check.
