Yeast and bacteria together biosynthesize plant hormones for weed control  

Plants regulate their growth using hormones, including a group called strigolactones that prevent excessive budding and branching. Strigolactones also help plant roots form symbiotic relationships with microorganisms that allow the plant to absorb nutrients from the soil. These two factors have led to agricultural interest in using strigolactones to control the growth of weeds and root parasites, as well as improving nutrient uptake. These root-extruding compounds also stimulate germination of w

Imagine having your own digital personal chef; ready to cook whatever you want, tailoring the shape, texture, and flavor just for you -- all at the push of a button. Engineers have been working on doing just that, using lasers for cooking and 3D printing technology for assembling foods. In their new study they discovered that laser-cooked meat shrinks 50% less, retains double the moisture content, and shows similar flavor development to conventionally cooked meat.

Scientists don't really know what kills many cancer patients, but fruit fly research could provide answers.

This suggests a novel strategy for extending a healthy life span in those with a cancer burden: block the tumor-generated chemicals and the damage they do.
