The most common lament I heard in Kabul in the last week was about the pricebitcoin koers wuro of food and the desperation of parents who are struggling to feed their children. Food prices are rocketing. Millions struggle to feed their families.
We do know, however, that they play a vital role in our ecosystems. Fungi decompose dead material into the building blocks of new soil. Fungi can also break down living material too – including trees. Fungi are the main drivers of wood decay, and a crucial resource for many invertebrates is a living tree with columns of fungal decay in the heartwood.solana beach school district haidee thesingHeart-rot fungi only move in when trees are mature, feeding on the dead wood at the centre of an ancient tree. When holes begin to form, the wood softens then insects and other species such as woodpeckers are able to excavate it further. Over time, a hollow forms and the cavity floor is lined with wood mould, a rich soil-like mulch.
"Heart-rot species are key," says Rutter. "These fungi are able to break down the lignin, the very hard part of the wood which is normally incredibly indigestible. Many heart-rot fungi happily eat the central dead wood without harming the living tissue on the outside – and can co-exist with a tree for 600 or 700 years. We want a tree to live a long time so the habitats can continue for as long as possible."To try and mimic this process in younger trees, Ancients of the Future is growing heart-rot fungi on blocks of wood in the lab, inserting the blocks into holes cut in young trees and recovering them with bark. They are left that way for a few years, then the blocks are removed to see if the fungi have taken hold inside the tree.The project is not the first to try this technique – fungi inoculation has been trialled before in North America where researchers found that fungal inoculation could reduce decay time from 100 years to just three when used in combination with traditional methods.Boddy explains why this new method of veteranisation may work better than previous methods: "We’re putting the fungi we want where we want it, rather than just hoping it turns up."She explains that the hollowing of ancient trees by fungal decay, previously seen as detrimental, is a natural part of the ageing process and can even prolong the lives of trees, feeding them nutrients from the inside.
Boddy's team has been using a new, minimally damaging DNA sampling technique to analyse the inoculated wood. It means the researchers are able to take a much smaller sample from the tree and get much more detailed information."Fungi are all around us," says Boddy. "Inside every tree trunk, every leaf, every stem, every bit of plant that’s decaying on the floor, in the soil beneath our feet. But we can’t see them which makes studying them very difficult. Now that we can extract DNA we can see exactly what’s there.""If we do have this policy, they will be expected to pay back the loans," he added.
Limits on how much energy firms charge customers will stay, the government and the energy regulator have said, despite the price of wholesale gas reaching record highs.On Monday, Mr Kwarteng and energy regulator Ofgem dismissed suggestions that the cap on energy prices would be lifted, saying that keeping it was the "clear and agreed position".Customers on some tariffs are protected from sudden hikes in wholesale gas prices through the energy price cap.This limits how much firms can charge per unit of gas.
The price cap covers 15 million households across England, Wales and Scotland.Customers will still continue to receive gas or electricity even if the energy supplier goes bust. Ofgem will move your account to a new supplier, but it may take a few weeks. Your new supplier should then contact you to explain what is happening with your account
While you wait to hear from your new supplier: check your current balance and - if possible - download any bills; take a photo of your meter readingIf you pay by direct debit, there is no need to cancel it straight away, Citizens Advice says. Wait until your new account is set up before you cancel itIf you are in credit, your money is protected and you'll be paid back. If you were in debt to the old supplier, you'll still have to pay the money back to your new supplier insteadOn Monday, Mr Kwarteng dismissed fears of energy shortages, saying: "There is absolutely no question of the lights going out or people being unable to heat their homes."
However, the price cap means firms are unable to pass on higher wholesale costs, which is forcing some - mostly smaller companies - to go out of business.The boss of one small firm, Utilita, told the BBC that it was not taking on any new customers because it could not afford to buy enough extra gas to supply them.Utilita chief executive Bill Bullen said that for every 1,000 new customers the firm attracted, it would have to take on £250,000 in additional costs per week.He said the government would end up spending billions of pounds on the crisis.
This money "would have been better spent on getting customers to reduce their energy consumption", he added.If an energy firm collapses, customers are automatically switched to a tariff provided by the new supplier. This is a tariff agreed with the regulator Ofgem, but it may well be more expensive than the deal they had with the former company which went bust.
What is the energy price cap?The energy cap is the maximum price suppliers in England, Wales and Scotland can charge customers on a standard - or default - tariff
Ofgem sets the cap level for summer and winter based on the underlying costs to supply energyEnergy bills are already due to rise by an average of £139 a year in October, but the price cap restricts further price hikes over winterThe current price cap is £1,138 a year for standard tariffs, but will rise to £1,277 in OctoberPresentational grey lineThe cost of the wholesale price surge is partly being covered by a 12% rise in the energy price cap next month - the maximum price suppliers are allowed to charge customers on a standard tariff.The energy price cap was introduced in January 2019 and is reviewed twice a year.
It applies only to standard variable or default tariffs. These types of tariff are typically the most expensive plan that a supplier offers.When fixed energy deals expire, as they generally do after one or two years, customers are likely to be put on these tariffs.
So far, four energy firms have gone to the wall, including People's Energy and Utility Point, and four more are expected to follow in the coming days.Industry sources fear there may be as few as 10 energy suppliers left by the end of the year, down from 70 in January.
Opposition politicians have expressed concern, with Labour's shadow economic secretary to the Treasury, Pat McFadden, describing the problems as a crisis that "should have been foreseen".Liberal Democrat leader Ed Davey, a former energy secretary, has said it is proof that the UK government's energy policy has been "lamentable".
And speaking on BBC Two's Newsnight programme on Monday, the former Brexit Secretary, David Davis, warned there was a risk of a "cost of living crisis" for new Tory voters such as "the plumber, the bricklayer, the lorry driver".He said his advice to Chancellor Rishi Sunak would be: "You think hard about the ordinary family's take-home pay and what they have to buy with it, because that will be a dictator of how people feel going in to the new year."Stacey Stothard followed all the advice. Aware that energy prices were rising, she shopped around to find a decent fixed deal for her gas and electricity.She saved £300 - or so she thought.
Her new energy supplier went bust and now she will be switched automatically to another one, and she is facing much higher bills, potentially amounting to hundreds of pounds more a year."It is just like watching the meter go up and up," she says. "I did the right thing - not going for the cheapest deal, but choosing a company with a decent customer service record."
Asian stocks were mixed on Tuesday as concerns persisted over Chinese property group Evergrande and its impact on the global markets.Japan's Nikkei 225 index closed 2.2% lower, but Hong Kong's Hang Seng index regained earlier losses to end up 0.5%.
There are concerns that Evergrande - a major Chinese property developer - is struggling to meet interest payments on more than $300bn of debts.Regulators have warned it could affect the country's financial system.
Investors fear that this could hit big banks exposed to Evergrande and companies like it, causing contagion in global markets.The jitters among the markets also come as the global economy is still recovering from the impact of the coronavirus.On Monday, the Dow Jones index in the US ended 1.8% lower. That followed similar falls in Europe, with Germany's Dax index losing 2.3%, and the Cac 40 in France down 1.7%.Major stock exchanges in mainland China were closed on Monday and Tuesday for the annual mid-Autumn festival.
Despite the recent falls, Japan's Nikkei is up by almost 30% compared to a year ago."The fear of an Evergrande bankruptcy appears to be leading to concern about China's very own Lehman [Brothers] moment, and a big overspill across the region," said Michael Hewson of CMC Markets.
Investors are also nervous that the US Federal Reserve, which meets on Tuesday and Wednesday, will confirm plans to cut back support for the US economy this year.Global stocks have rallied as economies reopen and central banks have provided trillions of dollars in support to boost growth.
But there are concerns of a decline if support is taken away at a time when the Delta variant of coronavirus continues to drag on recovery.Strategists at Morgan Stanley said they expected a 10% correction in America's S&P 500 index as the Fed starts to unwind its support.
