About 200,000 working days are lost in Germany every year due to insufficient sleep, with an economic loss of $60bln, or about 1.6% of its GDP, according to a 2016 Report of the RAND Corporation. Francesco Billari and Luca Stella (Bocconi University), with Osea Giuntella (University of Pittsburgh), in a study just published in the Journal of Economic Behavior and Organization, find that access to broadband Internet is one of the causes of such sleep deprivation.

Early life experiences influence DNA in the adult brain
In the perennial question of nature versus nurture, a new study suggests an intriguing connection between the two. Salk Institute scientists report in the journal Science that the type of mothering a female mouse provides her pups actually changes their DNA. The work lends support to studies about how childhood environments affect brain development in humans and could provide insights into neuropsychiatric disorders such as depression and schizophrenia. Continue reading “Early life experiences influence DNA in the adult brain”
New way to make light interact with matter
A new way of enhancing the interactions between light and matter, developed by researchers at MIT and Israel’s Technion, could someday lead to more efficient solar cells that collect a wider range of light wavelengths, and new kinds of lasers and light-emitting diodes (LEDs) that could have fully tunable color emissions.
