Contamination-eating microbes to be tested in the field

For years, the University of Toronto's Elizabeth Edwards and her team have been developing a potent mix of microbes that can chow down on toxic chemicals. Now, they are preparing to let them loose in the wild for the first ...

Skin in balance: Joint forces of polarity and cell mechanics

The cell polarity protein Par3 controls mechanical changes in the skin and plays an important role in cell division. Malfunction can lead to DNA damages. The balance of the system is of great importance—while too much differentiation ...

Researchers push for better policies around toxic chemicals

From high levels of lead found in school drinking water to industry sites releasing toxic heavy metals into the air, over 40 years of regulations in the United States have failed to protect human and environmental health ...

Portable gas detection shrinks to new dimensions

A sensor for detecting toxic gases is now smaller, faster and more reliable. Its performance sets it up for integration in a highly sensitive portable system for detecting chemical weapons. Better miniature sensors can also ...

Steroid binding to metabolic enzyme

The human cytochrome P450 enzymes are responsible for metabolizing a variety of substances—from lipids (fats) and steroid hormones to drugs and toxic chemicals.
