Study funded by NIH is decoding blue light’s mysterious ability to alter body’s natural clock

A study funded by the National Institutes of Health is unraveling the mystery of how blue light from residential and commercial lighting, electronic devices and outdoor lights can throw off-kilter the natural body clock of humans, plants and animals, leading to disease.

Exposure to blue light is on the increase, says chemist Brian Zoltowski, Southern Methodist University, Dallas, who leads the study. Continue reading

Business Insider: Your Smartphone Is Destroying Your Sleep

insomnia 220x170Business Insider Science Editor Jennifer Walsh tapped the sleep expertise of SMU Assistant Professor of Chemistry Brian D. Zoltowski to explain how artificial light from our smartphones and other digital devices causes sleep deprivation. Her article, “Your Smartphone Is Destroying Your Sleep,” published May 19.

Zoltowski’s lab at SMU studies one of the many proteins involved in an organism’s circadian clocks. Called a photoreceptor, the protein responds to light to predict time of day and season by measuring day length. Continue reading

Chemical probe confirms that body makes its own rotten egg gas, H2S, to benefit health

H2S 220x180A new study confirms directly what scientists previously knew only indirectly: The poisonous “rotten egg” gas hydrogen sulfide is generated by our body’s growing cells.

Hydrogen sulfide, or H2S, in small amounts plays a role in cardiovascular health. In the new study, chemists developed a chemical probe that reacts and lights up when live human cells generate hydrogen sulfide, says SMU’s Alexander R. Lippert. Continue reading

Circadian clock research may enable flexible designer plants; treat cancer and diabetes

How does a plant know when to sprout a leaf, fold its petals or bloom? Why do humans experience jet lag after a trip abroad?

The answer is the internal circadian clocks that are present in every organism and that respond to external cues such as light and temperature, says SMU chemist Brian D. Zoltowski. Zoltowski’s lab studies one of the many proteins involved in an organism’s circadian clocks. Continue reading
