Scientists learn how plants manipulate their soil environment to assure a cheap, steady supply of nutrients

by Rice University, Phys.org

The next time you’re thinking about whether to cook dinner or order a pizza for delivery, think of this: Plants have been doing pretty much the same thing for eons.

Researchers in Rice University’s Systems, Synthetic and Physical Biology program detailed how plants have evolved to call for nutrients, using convenient bacteria as a delivery service.

Wiping fungi on your face? Your makeup bag is a cesspool of germs, study says

by Joshua Bote, USA TODAY

Your makeup bag may be crawling with bacteria and fungi.

A report by researchers at Aston University in the United Kingdom, published in the peer-reviewed Journal of Applied Microbiology, found that an overwhelming majority of cosmetics are contaminated with E. coli, staphylococcus and other risky germs.

Scientists harness bacteria to create ‘living’ liquid crystals

by University of Chicago, Phys.org

Liquid crystals are widely used in technologies such as displays, which manipulate their orientation to display colors across the spectrum.

In traditional displays, liquid crystals are stationary and uniform, free of defects. But that stillness can be altered by adding bacteria to the crystals, creating what scientists and engineers call “living liquid crystals”: materials that can act autonomously. As bacteria swim around the liquid crystal, they generate “defects” that can be used for engineering purposes.
