Artificially sweetened drinks may not be heart healthier than sugary drinks

Sugary drinks and artificially sweetened beverages are associated with a higher risk of cardiovascular disease, which suggests artificially sweetened beverages may not be the healthy alternative they are often claimed to be, according to a research letter.

Research provides a new understanding of how a model insect species sees color

Through an effort to characterize the color receptors in the eyes of the fruit fly Drosophila melanogaster, researchers discovered the spectrum of light it can see deviates significantly from what was previously recorded.

UCF researcher is working to extend battery life in smartphones, electric cars

(University of Central Florida) A University of Central Florida researcher is working to make portable devices and electric vehicles stay charged longer by extending the life of the rechargeable lithium-ion batteries powering them.He is doing this by making the batteries more efficient, with some of his latest work focusing on keeping the anode from falling apart over time. The new technique is detailed in the journal Advanced Materials.

Metal deposits from Chinese coal plants end up in the Pacific Ocean, USC research shows

(University of Southern California) Emissions from coal-fired power plants in China are fertilizing the North Pacific Ocean with a metal nutrient important for marine life, according to new findings from a USC-led research team. The researchers believe these metals could change the ocean ecosystem, though it’s unclear whether it would be for better or worse.

Ancient Maya built sophisticated water filters

Ancient Maya in the once-bustling city of Tikal built sophisticated water filters using natural materials they imported from miles away, according to new research. A multidisciplinary team of anthropologists, geographers and biologists identified quartz and zeolite, a crystalline compound consisting of silicon and aluminum, that created a natural molecular sieve. Both minerals are used in modern water filtration.

Ancient origins of speed control during movement

Movement in animals is complex. Little has been known about how spinal inhibitory interneurons work to silence other neurons and related muscle groups in coordination with the active muscle groups across changing speeds. Now a research team has discovered in a study of zebrafish that there is a very orderly relationship between when these critical inhibitory neurons are born, their participation in different speeds of movement and what part of a motor neuron they innervate.
