Scientists in Britain and the United States say they have engineered a plastic-eating enzyme that could help in the fight against pollution.
The enzyme is able to digest polyethylene terephthalate, or PET — a form of plastic patented in the 1940s and now used in millions of tons of plastic bottles. PET plastics can persist for hundreds of years in the environment and currently pollute large areas of land and sea worldwide.
Researchers from Britain’s University of Portsmouth and the U.S. Department of Energy’s National Renewable Energy Laboratory made the discovery while examining the structure of a natural enzyme thought to have evolved in a waste-recycling center in Japan.
Finding that this enzyme was helping a bacteria to break down, or digest, PET plastic, the researchers decided to “tweak” its structure by adding some amino acids, said John McGeehan, a professor at Portsmouth who co-led the work.
This led to a serendipitous change in the enzyme’s actions — allowing its plastic-eating abilities to work faster.
“We’ve made an improved version of the enzyme better than the natural one already,” McGeehan told Reuters in an interview.
“That’s really exciting because that means that there’s potential to optimize the enzyme even further.”
The team, whose finding was published Monday in the Proceedings of the National Academy of Sciences journal, is now working on improving the enzyme further to see if it could be capable of breaking down PET plastics on an industrial scale.
“It’s well within the possibility that in the coming years we will see an industrially viable process to turn PET, and potentially other [plastics], back into their original building blocks so that they can be sustainably recycled,” McGeehan said.
Independent scientists not directly involved with the research said it was exciting, but cautioned that the enzyme’s development as a potential solution for pollution was still at an early stage.
“Enzymes are non-toxic, biodegradable and can be produced in large amounts by microorganisms,” said Oliver Jones, a Melbourne University chemistry expert. “There is strong potential to use enzyme technology to help with society’s growing waste problem by breaking down some of the most commonly used plastics.”
Douglas Kell, a professor of bioanalytical science at Manchester University, said further rounds of work “should be expected to improve the enzyme yet further.”
“All told, this advance brings the goal of sustainably recyclable polymers significantly closer,” he added. (VOA)
The new medical colleges being opened in Uttar Pradesh will be named after saints and sages.
The state government has issued an order naming four district hospitals that are being converted into medical colleges.
These district hospitals are in Bijnor, Fatehpur, Chandauli, and Siddharth Nagar.
The Bijnor medical college has been named after Mahatma Vidur, a philosopher during the Mahabharata era and uncle of the Pandavas and Kauravas.
The Chandauli medical college has been named after Baba Keenaram, said to be the founder of the Aghori sect.
The Siddharth Nagar district hospital will be called Madhav Prasad Tripathi Medical College after the BJP politician from the region. Tripathi, popularly known as Madhav Babu, was also the first Uttar Pradesh BJP chief. He was elected MP from Domariyaganj in 1977, besides being two times Jan Sangh MLA and also a member of the UP legislative council.
The Fatehpur hospital has been named Amar Shaheed Jodha Singh Ataiya Thakur Dariyawn Singh Medical College, after the freedom fighter of 1857.
It is said that he was among the first to use Guerrilla warfare against the British, as taught by freedom fighter Tatya Tope.
Meanwhile, according to official sources, the medical college in Deoria will be named after Maharishi Devraha Baba and the medical college of Ghazipur in the name of Maharishi Vishwamitra.
The medical college of Mirzapur will be in the name of Maa Vindhyavasini, the medical college of Pratapgarh in the name of Dr. Sonelal Patel and the medical college of Etah will be named after Veerangana Avantibai Lodhi. (IANS/JB)

Former Pakistan captain Inzamam-ul-Haq has picked India as the favourite to win the ongoing ICC Men's T20 World Cup in Oman and United Arab Emirates (UAE).
Inzamam feels that the Virat Kohli-led India have a greater chance of winning the trophy as the conditions in the Gulf nations are similar to the subcontinent, which makes India the most dangerous side in the event, according to Inzamam.
"In any tournament, it cannot be said for certain that a particular team will win' It's all about how much chance do they have of winning it. In my opinion, India have a greater chance than any other team of winning this tournament, especially in conditions like these. They have experienced T20 players as well," said Inzamam on his YouTube channel.
He said more than the Indian batters, the bowlers have a lot of experience of playing in the conditions. The Indian Premier League (IPL) was played recently in UAE and most of the Indian bowlers did well in that leg.
Inzy heaped praises on the Men in Blue for the confident manner in which they chased the target against Australia on a challenging track without needing Kohli's batting prowess.
"India played their warm-up fixture against Australia rather comfortably. On subcontinent pitches like these, India are the most dangerous T20 side in the world. Even today, if we see the 155 runs they chased down, they did not even need Virat Kohli to do so," he added.
Though he did not pick any favourite, Inzamam termed the India-Pakistan clash in the Super 12 on October 24 as the 'final before the final' and said the team winning it will go into the remaining matches high on morale,
"The match between India and Pakistan in the Super 12s is the final before the final. No match will be hyped as much as this one. Even in the 2017 Champions Trophy, India and Pakistan started and finished the tournament by facing each other, and both the matches felt like finals. The team winning that match will have their morale boosted and will also have 50 percent of pressure released from them," Inzamam added. (IANS/JB)

Skin problems like itchiness, dryness and flakiness can occur anytime if you're not moisturising your body enough. It is commonly observed that while many people take their skincare routine seriously, a majority of them neglect to moisturise the body. It is important to keep in mind that timing matters a lot when it comes to applying moisturisers. Therefore, knowing the appropriate time to apply body lotion is essential.
Take a look at the ideal times to moisturise your body shared by Kimi Jain, Head of Retail, KIMRICA.
Moisturising the body in the morning sets your skin up to face countless irritants and environmental factors during the day. The skin is constantly exposed to harsh chemicals and pollutants when you're outside which is why using a protective and soothing moisturiser while going out is necessary. Kimirica's Five Elements Body Lotion comes with natural Aloe Vera extracts that act as a rich source of antioxidants and vitamins that helps protect your skin and provide a deep nourishing effect.

After showering, Shaving and Washing hands
After you take a shower, your skin has the maximum moisture and moisturisers work effectively on hydrated skin. That is why dermatologists always recommend applying moisturiser right after getting out of the shower. When applied early, moisturisers are able to trap some water that's still in the body and hydrate the body. Shaving not only helps you to get rid of unwanted body hair but also removes the surface skin cells. To soothe any skin irritation and protect the exposed skin from dryness, apply any hydrating moisturiser that gives your skin a natural glow. The increasing use of antibacterial soaps and hand wash takes a toll on your hand disrupting the natural skin barrier. To protect your hands from cracking and dryness, you can use the brand's Bouquet Hand Lotion that comes with a rich combination of sweet almond oil, Shea butter, grape seed extracts, Olive Oil and Jojoba Oil.

During and After Your Flights
Travelling makes your skin dryer, the reason being the low humidity and the recycled air inside. As body lotions are available in small sizes, it is advisable that you should carry your body lotion and apply it during your flight and once you land as this will help in combating the skin drying issue.
Research has shown that the skin effectively repairs itself from 10 p.m. to 11 p.m. That's why you should always make sure to moisturise your skin on or before this time. Also, it has been observed that the skin's trans-epidermal water loss increases during sleep which takes away plenty of moisture from the skin. So, all these reasons make it quite clear as to why you should always moisturise your body before going to sleep.

Exfoliation is an important step in any skincare routine but applying body lotion post exfoliating is equally required. Exfoliating results in the removal of dead skin cells which makes space for a new layer of skin. Applying body lotion will help to soothe the top layer of skin and also strengthen the moisture barrier.
