Researchers are working on a new paper-based device that can be used to detect SARS-CoV-2 (coronavirus) within the wastewater of communities infected with the virus.
According to the study, published in the journal Environmental Science & Technology, rapid testing kits using paper-based devices could be used on-site at wastewater treatment plants to trace sources and determine whether there are potential COVID-19 carriers in local areas.
The wastewater-based epidemiology (WBE) approach could provide an effective and rapid way to predict the potential spread of COVID-19 by picking up on biomarkers in feces and urine from disease carriers that enter the sewer system.

“In the case of asymptomatic infections in the community or when people are not sure whether they are infected or not, real-time community sewage detection through paper analytical devices could determine whether there are COVID-19 carriers in an area to enable rapid screening, quarantine and prevention,” explained researcher Dr Zhugen Yang, Professor at Cranfield University in the UK.
WBE is already recognised as an effective way to trace illicit drugs and obtain information on health, disease and pathogens.
Dr Yang has developed a similar paper-based device to successfully conduct tests for rapid veterinary diagnosis in India and for malaria in blood among rural populations in Uganda.
Recent studies have shown that live SARS-CoV-2 can be isolated from the faeces and urine of infected people and the virus can typically survive for up to several days in an appropriate environment after exiting the human body.

According to the researchers, the paper device is folded and unfolded in steps to filter the nucleic acids of pathogens from wastewater samples, then a biochemical reaction with preloaded reagents detects whether the nucleic acid of SARS-CoV-2 infection is present.
Results are visible to the naked eye: a green circle indicating positive and a blue circle negative.
“We have already developed a paper device for testing genetic material in wastewater for proof-of-concept, and this provides clear potential to test for infection with adaption,” said Dr Yang.
“We foresee that the device will be able to offer a complete and immediate picture of population health once this sensor can be deployed in the near future,” Yang added.
Paper analytical devices are easy to stack, store and transport because they are thin and lightweight, and can also be incinerated after use, reducing the risk of further contamination, the study noted. (IANS)
Atop the Vindhyagiri hills in Karnataka, a 57-foot-tall statue stands. This is the statue of Lord Gomateshwara, or Bahubali, as he is known to the local patrons. The surrounding area is filled with temples where each of the many Jain Tirthankaras sits.
Sharavanabelagola is named after a pond that is located at the foothills. 'Bel' in Kannada means white, and 'kola' means pond. This is a sacred water body to the activities of the temples. It is a tourist attraction and a pilgrim destination located 85 kilometres from Mysore, and 145 kilometres from the capital, Bangalore.

Since the statue is placed at such a great height, pilgrims are made to make a journey to the top of the hill by foot. They are required to climb the stone steps barefoot as an act of piety and devotion. Palanquins are offered only to senior citizens who wish to worship at the temple.
In 3 B.C, when India was ruled by the Mauryan Dynasty, Chandragupta Maurya became a Jain monk and took up residence in the Chandragiri and Vindhyagiri hills. He is supposedly responsible for the establishment of the temple complex at Shravanabelagola, where he lived till he died. Later on, his grandson, Ashoka made some additional changes to the place.

Every twelve years, a Mahamastabhisheka is conducted, and Jains from every part congregate to witness it. The statue is washed with water, rice flour, sugarcane juice, saffrom, sandalwood paste, gold, and silver flowers, curd, ghee, milk, and turmeric, and all the monks offer special prayers. The surrounding temples and rocks are preserved as archaeological wonders owing to the 800 edicts and inscriptions found here which span 600 to 1830.

The author who named the book after her twin sons -- Puhor and Niyor -- is a parent who has seen and heard the tales of ridicule and discrimination suffered by many in India and beyond. She says the book is an artistic illustration for kids that details how different families can live and coexist. Whether it's children with two dads or two moms, children with a single dad or single mom, and even multiracial family units, Borthakur's book teaches love, understanding, and compassion towards unconventional families.
Beyond race, gender, color, and ethnicity which have formed the bases for discrimination since the beginning of time, this book aims to bring to light a largely ignored issue. For so long, single parents have been treated like a taboo without any attempt to understand their situations; no one really cares how or why one's marriage ended but just wants to treat single parents as villains simply for choosing happiness and loving their children.
Homosexual parents, a relatively new family system, is another form that has suffered hate and discrimination for many years. Pritisha emphasizes the need to understand that diversity in people and family is what makes the world beautiful and colourful. 'Puhor and Niyor's Mural of Family Stories' is a firm but compassionate statement against all forms of discrimination on the bases of sexual identity, gender, race, and even differences in background

Written for a global audience, the book is targeted at kids between the ages of five and 10, the reason it is embellished with colourful images of families of different types is to appeal to children's sense of sight and drive home the message at the same time. Borthakur believes children are the best place to start because the ages between five and 10 are the most formative, where little ones pick up habits, beliefs and perceptions.
The Guwahati-born author says, "With this book, I'm not trying to take away the job of parents in forming habits, I simply want to do my part as a parent. It is important that we impart the right values in our kids in a bid to build a better, more inclusive and tolerant global society that is fair to everyone." The author's first attempt at a book was an Assamese poetry 'Anubhav', published in 2010.
Set to be published under the label of Author's Channel, the book is like an adventure; a journey into uncharted territories, untouched subjects and matters long ignored. In her words. "The book takes a critical stand in defense of people in society who have had to undergo severe emotional torture for no cause of theirs. It is a terrible conception to think such people any less of a human just for being different," says publisher Aruna Naidu. By September 30, this title, priced at Rs 299, will be available online and in offline bookstores. (IANS/ MBI)

If you feel that clean and well-groomed hands are just an essential prerequisite for women, you might like to think twice. Men should equally pay attention to their hands because our hand houses 1,500 bacteria living on each square centimeter of its skin. You can easily assume what havoc it can create in our body because in India we have the culture of eating with our hands and spaces beneath nails can become breeding heaven for germs. Moreover, clean and maintained hands boost confidence in their daily life activities. Therefore, it's important to keep your hands clean irrespective of your gender by washing or sanitizing at regular intervals. And, to keep them groomed, you don't have to visit a salon.
Rajesh U Pandya, Managing Director, KAI India, gives easy and completely doable tips to follow at home:
* Refrain from harsh soaps: You should be mindful of the soap you are using to wash your hands. Your soap can have a moisturizing element in it like aloe vera or shea butter. Ensure that you're washing your hands with normal water as hot water can make your hand's skin dry and scaly.

* Clip your nails regularly: Make use of your personal nail clipper to cut your nails. After cutting your nails at a comfortable length also file them using a nail filer. Never share your nail care clipper as the germs can get transferred to your loved ones. Also, don't forget to use grime remover to remove hidden germs in corners and beneath nails. Also, you may like to file your nails to have a smooth finish.
* Good quality Nail Clipper: Do not use a rusted or chromium coated nail clipper as it might be harmful to skin and might cause dangerous bacterial infections.
* Stop the habit of nail chewing: Sometimes anxiety or extreme boredom can lead to chewing of nails. This habit only makes your nails uneven and ugly. Sometimes, our unclean nail folds give rise to viral, bacterial or fungal infections, which in turn can make us sick if we chew our nails.

* Exfoliate your hands: Similar to the way you exfoliate your face; your hands also need it. It helps to keep the dry skin at bay and keep your hands soft. You can buy a scrub or make one at home using brown sugar and olive oil. After scrubbing, you need to massage your hands with moisturizer.

* Don't use your nails as tools: Always keep in mind that your nails are like jewels. Never use them to pry things open such as pop cans, removing keys from the ring, opening letters, or scraping off labels. This results in unnecessary breakage of nails, making your hands look dirty.
