 Algae may be a new green power source: Study


November 28, 2015: A team led by Concordia University engineering professor Muthukumaran Packirisamy created a power cell that harnesses electrical energy from the photosynthesis and respiration of blue-green algae.

Also known as cyanobacteria, blue-green algae are the most prosperous microorganisms on Earth, evolutionarily speaking, researchers said.

They occupy a broad range of habitats across all latitudes. And they have been here forever: the planet's early fauna and flora owe their makeup to cyanobacteria, which produced the oxygen that ultimately allowed higher life forms to flourish.

Currently, the photosynthetic power cell exists on a small scale, and consists of an anode, cathode and proton exchange membrane. The cyanobacteria or blue green algae are placed in the anode chamber.

As they undergo photosynthesis, the cyanobacteria release electrons to the electrode surface. An external load is connected to the device to extract the electrons and harness power. Researchers hope that the micro photosynthetic power cells will soon be used in various applications, such as powering cell phones and computers.

Google's new logo

   Google's new logo

NEW DELHI, September 2, 2015: Google is all set to don a different look. The internet numero uno has unveiled a new logo just weeks after a surprise reorganization under a newly-formed parent company called Alphabet.

The revised design features the same mix of blue, red, yellow and green that Google has been using throughout its nearly 17-year history, though the hues are slightly different shades.

The overhaul will change the appearance of the letter 'g' that Google uses as its shorthand logo on the smaller screens of smartphones and other mobile devices. The letter 'g' will now be capitalized and displayed in colour instead of being kept lowercase and white.

A swirl of dots in Google's colours will also appear when a spoken command for information is being processed or one of the company's other services is performing a task.

Google believes its new logo will provide a more versatile identity suited for seamless computing across devices. As the company said in a blog post, "Today we're introducing a new logo and identity family that reflects this reality and shows you when the Google magic is working for you, even on the tiniest screens. As you'll see, we've taken the Google logo and branding, which were originally built for a single desktop browser page, and updated them for a world of seamless computing across an endless number of devices and different kinds of inputs.

Google also invented a new typeface called 'Product Sans' that is meant to resemble the simple printing in a grade-school book. It will replace a serif typeface that Google has been using in its logo for more than 16 years
