Cryo-em freezes the funk: How scientists visualized a pungent protein
Most people have witnessed -- or rather smelled -- when a protein enzyme called sulfite reductase works its magic. This enzyme catalyzes the chemical reduction of sulfite to hydrogen sulfide. Hydrogen sulfide is the rotten egg smell that can occur when organic matter decays and is frequently associated with sewage treatment facilities and landfills. But scientists have not been able to capture a visual image of the enzyme's structure until now, thus limiting their full understanding of how it works.

Home water-use app improves water conservation
A new study has found that a smartphone app that tracks household water use and alerts users to leaks or excessive consumption offers a promising tool for helping California water agencies meet state-mandated conservation goals. The study found that use of the app -- called Dropcountr -- reduced average household water use by 6%, with even greater savings among the highest water users.

How brain stimulation alleviates symptoms of Parkinson's disease
Persons with Parkinson's disease increasingly lose their mobility over time and are eventually unable to walk. Hope for these patients rests on deep brain stimulation, also known as a brain pacemaker. In a current study, researchers investigated whether and how stimulation of a certain region of the brain can have a positive impact on ambulatory ability and provide patients with higher quality of life. To do this, the researchers used a technique in which the nerve cells are activated and deactivated via light.

Assembly instructions for enzymes
In biology, enzymes have evolved over millions of years to drive chemical reactions. Scientists have now derived universal rules to enable the de novo design of optimal enzymes. As an example, they considered the enzymatic reaction of breaking a dimer into two monomer molecules. Considering the geometry of such an enzyme-substrate-complex, they identified three golden rules that should be considered to build a functional enzyme.

A dental floss that can measure stress
Scientists create a floss pick that samples cortisol within saliva as a marker of stress and quantifies it with a built-in electrode. The system uses a polymer casting technology that can be adapted to capture a wide a range of markers, such as estrogen for tracking fertility, or glucose for tracking diabetes. Ease of use allows monitoring to be incorporated into many areas of treatment.
