A potentially transformative breakthrough in the global fight against climate change has been made by scientists in the UK and America.
A plastic-eating ‘super-enzyme’ has been created by scientists at the University of Portsmouth, UK, and the National Renewable Energy Laboratory, US, which could lead to a major reduction in both plastic pollution and greenhouse gases.
The enhanced enzyme is able to dispose of PET (polyethylene terephthalate), the plastic used in soft drinks and fruit juice packaging, as well as PEF (polyethylene furanoate), a sugar-based bioplastic.
PET is non-biodegradable and can take hundreds of years before decomposing.
The same team of scientists had already discovered one enzyme which eats PET called PETase, paving the way for a revolution in recycling.
This enzyme has now been combined with MHETase which is found in the rubbish-dwelling bacteria that live on plastic bottles.
The result is a potent cocktail that breaks down plastic up to six times faster than PETase alone.
Prof John McGeehan of the Centre for Enzyme Innovation at the University of Portsmouth, who led the study, said that it “seemed natural to see if we could use [PETase and MHETase] together, mimicking what happens in nature.”
“Our first experiments showed that they did indeed work better together, so we decided to try to physically link them, like two Pac-men joined by a piece of string,” he said.
The enzymes were studied using Diamond Light Source, a device which harnesses intense beams of X-rays that are 10 billion times brighter than the sun, to observe individual atoms.
The super-enzyme raises the prospect of a step change in the battle against plastic waste, a global blight which has so far proved intractable.
"This is quite a significant leap forward because the plastic that ends up in our oceans today is going to take hundreds of years to break down naturally," Prof McGeehan told PA.
"[Eventually] through sunlight and wave action, it will start to break down into smaller and smaller pieces – and we will end up with microplastics, which is a serious problem for the organisms that live in the environment."
By returning plastic to its original building blocks, it can be made and reused endlessly, reducing reliance on fossil fuels such as oil and gas.
The auspicious discovery also opens up “new avenues for further improvements” said Prof McGeehan. His team is now looking for ways to expedite the process so it can compete with oil.

How green is the expo nursery?
Some 400,000 shrubs and 13,000 trees in the on-site nursery
An additional 450,000 shrubs and 4,000 trees to be delivered in the months leading up to the expo
Ghaf, date palm, acacia arabica, acacia tortilis, vitex or sage, techoma and the salvadora are just some heat tolerant native plants in the nursery
Approximately 340 species of shrubs and trees selected for diverse landscape
The nursery team works exclusively with organic fertilisers and pesticides
All shrubs and trees supplied by Dubai Municipality
Most sourced from farms, nurseries across the country
Plants and trees are re-potted when they arrive at nursery to give them room to grow
Some mature trees are in open areas or planted within the expo site
Green waste is recycled as compost
Treated sewage effluent supplied by Dubai Municipality is used to meet the majority of the nursery’s irrigation needs
Construction workforce peaked at 40,000 workers
About 65,000 people have signed up to volunteer

What it means to be a conservationist
Who is Enric Sala?
Enric Sala is an expert on marine conservation and is currently the National Geographic Society's Explorer-in-Residence. His love of the sea started with his childhood in Spain, inspired by the example of the legendary diver Jacques Cousteau. He has been a university professor of Oceanography in the US, as well as working at the Spanish National Council for Scientific Research and is a member of the World Economic Forum’s Global Future Council on Biodiversity and the Bio-Economy. He has dedicated his life to protecting life in the oceans. Enric describes himself as a flexitarian who only eats meat occasionally.
What is biodiversity?
According to the United Nations Environment Programme, all life on earth – including in its forests and oceans – forms a “rich tapestry of interconnecting and interdependent forces”. Biodiversity on earth today is the product of four billion years of evolution and consists of many millions of distinct biological species. The term ‘biodiversity’ is relatively new, popularised since the 1980s and coinciding with an understanding of the growing threats to the natural world including habitat loss, pollution and climate change. The loss of biodiversity itself is dangerous because it contributes to clean, consistent water flows, food security, protection from floods and storms and a stable climate. The natural world can be an ally in combating global climate change but to do so it must be protected. Nations are working to achieve this, including setting targets to be reached by 2020 for the protection of the natural state of 17 per cent of the land and 10 per cent of the oceans. However, these are well short of what is needed, according to experts, with half the land needed to be in a natural state to help avert disaster.

Teaching your child to save
Pre-school (three - five years)
You can’t yet talk about investing or borrowing, but introduce a “classic” money bank and start putting gifts and allowances away. When the child wants a specific toy, have them save for it and help them track their progress.
Early childhood (six - eight years)
Replace the money bank with three jars labelled ‘saving’, ‘spending’ and ‘sharing’. Have the child divide their allowance into the three jars each week and explain their choices in splitting their pocket money. A guide could be 25 per cent saving, 50 per cent spending, 25 per cent for charity and gift-giving.
Middle childhood (nine - 11 years)
Open a bank savings account and help your child establish a budget and set a savings goal. Introduce the notion of ‘paying yourself first’ by putting away savings as soon as your allowance is paid.
Young teens (12 - 14 years)
Change your child’s allowance from weekly to monthly and help them pinpoint long-range goals such as a trip, so they can start longer-term saving and find new ways to increase their saving.
Teenage (15 - 18 years)
Discuss mutual expectations about university costs and identify what they can help fund and set goals. Don’t pay for everything, so they can experience the pride of contributing.
Young adulthood (19 - 22 years)
Discuss post-graduation plans and future life goals, quantify expenses such as first apartment, work wardrobe, holidays and help them continue to save towards these goals.

US tops drug cost charts
The study of 13 essential drugs showed costs in the United States were about 300 per cent higher than the global average, followed by Germany at 126 per cent and 122 per cent in the UAE.
Thailand, Kenya and Malaysia were rated as nations with the lowest costs, about 90 per cent cheaper.
In the case of insulin, diabetic patients in the US paid five and a half times the global average, while in the UAE the costs are about 50 per cent higher than the median price of branded and generic drugs.
Some of the costliest drugs worldwide include Lipitor for high cholesterol.
The study’s price index placed the US at an exorbitant 2,170 per cent higher for Lipitor than the average global price and the UAE at the eighth spot globally with costs 252 per cent higher.
High blood pressure medication Zestril was also more than 2,680 per cent higher in the US and the UAE price was 187 per cent higher than the global price.
