Can Life Ever Be Perfectly Adapted to Its Environment? - Facts So Romantic
▻http://nautil.us/blog/can-life-ever-be-perfectly-adapted-to-its-environment
Can an organism ever become perfectly evolved? In Richard Lenski’s lab at Michigan State University, scientists are trying to see if that’s possible. The idea grew out of the lab’s Long-Term Evolution Experiment, started in 1988, with Escherichia coli; in 2010, they celebrated 50,000 generations (500 occur every 75 days). The lab has 12 populations of the bacteria inhabiting their own climate-controlled flasks of swirling nutrient solution, each like a finch-less Galapagos—an experiment in evolution by natural selection, but one that has been stripped to its bare essentials. For the past 28 years, there has been essentially no change in the bacteria’s environment, and the only competition they face is with each other over scarce glucose. If there were ever a setting where a living organism (...)

This report presents a simple yet effective method for spoofing thefingerprint sensor embedded in a mobile phone using a 2D fingerprint image printed on a special paper. The spoof fingerprint is generated automatically. The main steps of our process are summarized as
follows.
1) Install three AgIC4 silver conductive ink cartridges as well as a normal black ink cartridge in a color inkjet printers
2) Scan the target fingerprint image (of the authorized user) at 300 dpi or higher resolution;
3) Mirror (reverse the image in the horizontal direction) and print the original or binarized fingerprint image on the glossy side of an AgIC special paper
The experiment worked successfully with Samsung Galaxy S6 and Huawei Hornor 7 phones

Solar energy that doesn’t block the view | MSUToday | Michigan State University
▻http://msutoday.msu.edu/news/2014/solar-energy-that-doesnt-block-the-view
A team of researchers at Michigan State University has developed a new type of solar concentrator that when placed over a window creates solar energy while allowing people to actually see through the window.
It is called a transparent luminescent solar concentrator and can be used on buildings, cell phones and any other device that has a clear surface.
Bacteria Produces 24-Karat Gold From Toxic Chemicals (PHOTOS)

Scientists have developed a bug which produces pure gold.
The team at Michigan State University say that they found the bacteria Cupriavidus metallidurans is able to take so-called liquid gold (gold chloride, a toxic chemical found in nature) and turn it into 24-karat gold.
The process has been named microbial alchemy - and that’s exactly what it appears to be.
