Microbes can be used in Large Quantities to Convert Light into Energy

At least four years since scientists at the State University of New York-Binghamton developed a bacteria-powered battery on a single sheet of paper, able to power disposable electronic devices.

At least four years since scientists at the State University of New York-Binghamton developed a bacteria-powered battery on a single sheet of paper, able to power disposable electronic devices. These biobatteries were supposed to revolutionise the battery landscape, but they didn’t.

Before that, in 2015, a fully integrated and self-powered system on paper was also developed so that it could work independently and in a self-sustainable manner as a low-cost solution in specific use cases.

It was capable of generating power from microbial metabolism, delivering onboard energy to the next generation of paper-based systems with one drop of bacteria-containing liquid derived from renewable and sustainable water sources.

Now, researchers at the University of British Columbia have found a cheap and sustainable way to build a solar cell using bacteria that convert light into energy, reports.

The cell generated a current stronger than any previously recorded from such a device and worked equally efficiently in low light and bright light. The innovation could be a step towards wider adoption of solar power in places where overcast skies are common.

It has already been demonstrated that bacteria can produce energy from sunlight through photosynthesis. Certain bacteria produce a chemical that makes it possible and scientists have put these chemicals into solar cells although it is a complicated process.

However, the UBC research group did the smart thing and used the bacteria directly, with their chemicals intact. These chemicals are a form of dye that turns light into energy.

The bacteria used in this case are none other than Escherichia coli, or E. coli, that cause so much trouble to humans in everyday life.

According to the report, the new method is not quite as robust as traditional solar energy, but it has the distinct advantage of being able to cope with lower light in addition to bright sunlight.

The use of bacteria for solar energy is also thought to be more economical, which the researchers (Indians are among them) demonstrated with the density of the biogenic cells.

When Algorithms Predict Hits and Flops

Artificial intelligence (AI) has come to Hollywood. A company, in business since 2015, has developed algorithms to predict which Hollywood movies will be box-office hits.

ScriptBook says it applies hard science to predict screen successes using a Script2Screen solution that could benefit producers, distributors, film sales agents, talent agents and film funds.

The company claims that its solution focusses on the storytelling metric and uses AI to analyse screenplays and deliver an objective assessment of a script’s commercial and critical success.

ScriptBook says its AI analysis is objective and fair, treating every screenplay equally and without bias. The idea is to help Hollywood produce many more profitable movies without giving up on creativity and compelling storytelling.

At a presentation at the recently concluded Karlovy Vary International Film Festival, ScriptBook founder Nadira Azermai said that by analysing screenplays, ScriptBook retroactively identified as box-office failures 22 out of the 32 Sony movies that lost money during 2015-17 when Sony Pictures released a total of 62 films, reports Variety.

“If Sony had used our system, they could have eliminated 22 movies that failed financially,” Azermai said.
