November 26, 2016: Domestic sewage contains organic wastes, that are mainly from toilets and kitchens may prove to be a source of energy that can be harvested by using hungry bacteria, scientists say.

According to PTI, Francis Meerburg from Ghent University in Belgium said, “The levels of organic matter in sewage are too low to be directly recovered. We investigated how we can use bacteria to capture this material.”

Meerburg further added, “Our approach is unique because we have developed a high-rate variation of the so-called contact stabilisation process.”

Nico Boon, from Ghent University said,”We periodically starve the bacteria, in a kind of ‘fasting regimen’. Afterwards, wastewater is briefly brought into contact with the starved bacteria which are gluttonous and gobble up the organic matter without ingesting all of it.”

Boon further added, “This enables us to harvest the undigested materials for the production of energy and high-quality products. We starve the rest of the bacteria, so that they can purify fresh sewage again.”

Almost, up to 55 percent of the organic matter could be recovered from sewage by using contact stabilisation process.

The existing processes cannot recover more than 20 to 30 percent, so, this is a huge step forward.
The researchers also calculated that this amount can provide ample amounts of energy in order to completely treat the sewage without the need for external electricity.

Siegfried Vlaeminck, the professor at Ghent University said, “This is an important step in the direction of wastewater treatment that is energy neutral, or even produces energy.”

Aadhaar Helpline Mystery: French Security Expert Tweets of doing a Full Disclosure Tomorrow about Code of the Google SetUP Wizard App

Google’s admission that it had in 2014 inadvertently coded the 112 distress number and the UIDAI helpline number into its setup wizard for Android devices triggered another controversy on Saturday as India’s telecom regulator had only recommended the use of 112 as an emergency number in April 2015.

After a large section of smartphone users in India saw a toll-free helpline number of UIDAI saved in their phone-books by default, Google issued a statement, saying its “internal review revealed that in 2014, the then UIDAI helpline number and the 112 distress helpline number were inadvertently coded into the SetUp wizard of the Android release given to OEMs for use in India and has remained there since”.

However, the Telecom Regulatory Authority of India (TRAI) recommended only in April 2015 that the number 112 be adopted as the single emergency number for the country.

According to Google, “since the numbers get listed on a user’s contact list, these get  transferred accordingly to the contacts on any new device”.

Google was yet to comment on the new development.

Meanwhile, French security expert that goes by the name of Elliot Alderson and has been at the core of the entire Aadhaar controversy, tweeted on Saturday: “I just found something interesting. I will probably do full disclosure tomorrow”.

“I’m digging into the code of the @Google SetupWizard app and I found that”.

“As far as I can see this object is not used in the current code, so there is no implications. This is just a poor coding practice in term of security,” he further tweeted.

On Friday, both the Unique Identification Authority of India (UIDAI) as well as the telecom operators washed their hand of the issue.

While the telecom industry denied any role in the strange incident, the UIDAI said that he strange incident, the UIDAI said that some vested interests were trying to create “unwarranted confusion” in the public and clarified that it had not asked any manufacturer or telecom service provider to provide any such facility.

Twitter was abuzz with the new development after a huge uproar due to Telecom Regulatory Authority of India (TRAI) Chairman R.S. Sharma’s open Aadhaar challenge to critics and hackers.

Ethical hackers exposed at least 14 personal details of the TRAI Chairman, including mobile numbers, home address, date of birth, PAN number and voter ID among others. (IANS)
