Energy from sunlight: Further steps towards artificial photosynthesis
June 24, 2016 01:43 PM - University of Basel via EurekAlert!

Chemists from the Universities of Basel and Zurich in Switzerland have come one step closer to generating energy from sunlight: for the first time, they were able to reproduce one of the crucial phases of natural photosynthesis with artificial molecules. Their results have been published by the journal Angewandte Chemie (international edition).

Green plants are able to temporarily store electric charges after the absorption of sunlight by using a so-called molecular charge accumulator. The two research teams were able to observe this process in artificial molecules that they created specifically for this experiment.

Chicago's urban farming produces fresh veggies all year, 24/7
June 22, 2016 10:29 AM - Maurice Picow

Hydroponics and new, high-tech urban agricultural techniques are now growing fresh food in the middle of Manhattan and other large metropolitan centers globally. People are catching onto the taste and business opportunities of urban agriculture: find it growing in Middle Eastern cities such as Cairo, Egypt too!

Urban farming in midwestern American cities like Chicago has had its limitations due to adverse winter weather conditions at least 9 months a year. New indoor farming techniques use vertical farming, special indoor LED lighting and hydroponic systems that pump soybean and kelp-infused water through a temperature and humidity-controlled system, nearly 24 hours a day, 365 days a year.

Bright Lighting Encourages Healthy Food Choices

Food and Brand Lab, Cornell University.

Dining in dimly lit restaurants has been linked to eating slowly and ultimately eating less than in brighter restaurants, but does lighting also impact how healthfully we order?

New research findings forthcoming in the Journal of Marketing Research illustrate that those dining in well-lit rooms are about 16-24% more likely to order healthy foods than those in dimly lit rooms. Furthermore, the researchers found evidence that this effect is due mainly to the level of diners’ alertness. “We feel more alert in brighter rooms and therefore tend to make more healthful, forward-thinking decisions,” explains lead author Dipayan Biswas, PhD, University of South Florida.
