KERA: The Bright Side And Dark Side Of Blue Light

Brian Zoltowski, SMU, blue light, circadian clock KERA Public Radio journalist Justin Martin explored the good and bad of blue light in our environment with Brian Zoltowski, an assistant professor in the SMU Department of Chemistry. Zoltowski's lab was awarded $320,500 from the National Institute of General Medical Sciences of the National Institutes of Health to continue its research on the impact of blue light on the circadian clock of humans and other organisms.

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

An SMU 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 throws off the natural body clock of humans, plants and animals, leading to disease, says SMU chemist Brian Zoltowski.

Scientific American: How your smartphone messes with your brain — and your sleep

SMU, sleep, smart phones, Zoltowski, chemistryScientific American science blogger Josh Fischman drew on 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. His blog article, "How your smartphone messes with your brain — and your sleep," published May 20 and has been heavily shared through social media.

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.

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

A new study confirms directly what scientists previously knew only indirectly: The poisonous “rotten egg” gas hydrogen sulfide, which plays a role in cardiovascular health, is generated by our body's growing cells.

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.

CBS DFW: Is Aerial Spraying Safe?

CBS Channel 11 reporter Ginger Allen interviewed SMU chemist Brian Zoltowski for the station's Aug. 15 report on aerial spraying over Dallas County to kill mosquitos that may be carrying West Nile Virus. The report comes in the wake of a decision by Dallas County to address the spread of West Nile Virus with aerial spraying of a pesticide called Duet.

Science Daily: Scientists Find Simple Way to Produce Graphene

_53648191_graphene_chip.jpgThe online science news site Science Daily has covered the research of SMU Chemistry Department Professor John A. Maguire. The June 21 article "Scientists Find Simple Way to Produce Graphene" reports the news that Maguire and a team lead by scientists from Northern Illinois University have discovered a simple method for producing high yields of graphene, a highly touted carbon nanostructure that some believe could replace silicon as the technological fabric of the future. Read the full story.

Dallas Business Journal: Firm is out to prevent neuron loss

Biehl%20lab%20400x300.jpgInvestigators at SMU and University of Texas at Dallas have discovered a family of small molecules that shows promise in protecting brain cells against nerve-degenerative diseases such as Parkinson's, Alzheimer's and Huntington's. SMU's work is led by Chemistry Department Professor Edward R. Biehl.

Health care journalist Bill Hethcock covered the research for The Dallas Business Journal. His Feb. 25 article "Firm is out to prevent neuron loss" details how Dallas-based startup EncephRx Inc. was granted worldwide license to develop the jointly owned compounds.
