Evolution of consumption: A psychological ownership framework

Researchers from Boston University, Rutgers University, University of Washington, Cornell University, and University of Pennsylvania published a new paper in the Journal of Marketing that proposes that preserving psychological ownership in the technology-driven evolution of consumption underway should be a priority for marketers and firm strategy.

Decaying jellyfish blooms can cause temporary changes to water column food webs

Decaying jellyfish blooms fuel the rapid growth of just a few strains of seawater bacteria, effectively keeping this organic material within the water column food web, reveals a new study published in Frontiers in Microbiology. This research furthers our understanding of how marine ecosystems are impacted by jellyfish blooms, which have been observed to be happening on a more frequent basis.

Density fluctuations in amorphous silicon discovered

For the first time, a team at HZB has identified the atomic substructure of amorphous silicon with a resolution of 0.8 nanometres using X-ray and neutron scattering at BESSY II and BER II. Such a-Si:H thin films have been used for decades in solar cells, TFT displays, and detectors. The results show that three different phases form within the amorphous matrix, which dramatically influences the quality and lifetime of the semiconductor layer.

Researchers develop a method for tuning biomolecular receptors for affinity and cooperativity

Our biological processes rely on a system of communications—cellular signals—that set off chain reactions in and between target cells to produce a response. The first step in these often complex communications is the moment a molecule binds to a receptor on or in a cell, prompting changes that can trigger further signals that propagate across systems. From food tasting and blood oxygenation during breathing to drug therapy, receptor binding is the fundamental mechanism that unlocks a multitude of biological functions and responses.

How many habitable planets are out there?

Thanks to new research using data from the Kepler space telescope, it’s estimated that there could be as many as 300 million potentially habitable planets in our galaxy. Some could even be pretty close, with several likely within 30 light-years of our Sun. The findings will be published in The Astronomical Journal, and research was a collaboration of scientists from NASA, the SETI Institute, and other organizations worldwide.
