Scientist bitten by deadly snakes 200 TIMES helps create ‘unparalleled' anti-venom to save thousands of lives
A WACKY scientist has allowed the world's deadliest snakes to bite him over 200 times to help create an "unparalleled" anti-venom.
Tim Friede has been injected by snake toxins over 850 times across his 18-year career and once even fell into a coma due to two cobra bites.

Snake venom kills up to 140,000 people each year and can leave over 420,000 people needing life altering amputations.
The cases remain so high due to their being no universal antivenom against all snakebites.
But after nearly two decades of death-defying work, Tim's research may have finally paid off.
His fearless antibodies have been shown to protect against fatal doses from a wide range of dangerous species in recent animal tests.
The American initially allowed himself to be bitten to help further his career on YouTube where he handled a range of snakes.
He believed it would help him build up an immunity to protect himself when finding some of the world's worst snakes.
His bizarre plan once left the former truck mechanic fighting for his life after two Egyptian cobra bites in quick succession left him in a coma for days.
Tim told the BBC he "didn't want to die" and so when he awoke and was back to full health he used his second chance at life to help others survive.
He explained: "It just became a lifestyle and I just kept pushing and pushing and pushing as hard as I could push for the people who are 8,000 miles away from me who die from snakebites."
His brave work was soon noticed by research teams who got in contact and asked to examine his blood.
The team of scientists were searching for a type of immune defence which had neutralised antibodies - something they believed Tim may have developed.
Dr Jacob Glanville, chief executive of biotech company Centivax, reached out to him and asked if they could take a blood sample for testing.
Tim soon agreed after he was told his body has been able to repel venom which would "normally kill a horse", according to Dr Glanville.
The research focused on two families of venomous snakes which included coral snakes, mambas, cobras, taipans and kraits.
These reptiles use neurotoxins in their venom to paralyse their victim to the point where their muscles can no longer supply the body with enough oxygen.
Researchers handpicked 19 of these creatures which are considered as being among the deadliest snakes on the planet.
Soon after analysing Tim's blood they uncovered two broadly neutralising antibodies that target neurotoxins, according to their work which is detailed in the journal Cell.
A third drug was later added to the antivenom cocktail before it was used on mice.

Out of 19 test subjects, 13 survived lethal doses of snake venom.
The remaining six were found to have partial protection against the poison.
Dr Glanville described the results as "unparalleled" in the current world of antivenom research.
He also believes this means the cocktail will likely cover a whole range of other snakes.
The team is now trying to see if they can add a fourth component to the drug mixture in order to offer full protection to venom.
Currently, testing has only been done on elapid snake venom which covers the two most common families of deadly snakes.
The other major snake types which contribute to global death rates are vipers.
Tim's antibodies are really quite extraordinary - he taught his immune system to get this very, very broad recognition
Professor Peter KwongColumbia University
They use haemotoxins to attack blood cells rather than neurotoxins which target muscles - a key difference to elapids.
But Professor Peter Kwong, a researcher at Columbia University, believes the initial results prove that one day a complete antivenom will be discovered.
He said: "I think in the next 10 or 15 years we'll have something effective against each one of those toxin classes."
The ultimate goal is to create a single antivenom or discover two injections which cover elapids and vipers.
And Tim is planning on helping out for as long as he can.
He said: "I'm doing something good for humanity and that was very important to me. I'm proud of it. It's pretty cool."
Prof Kwong says his team owes Tim and the world a huge thank you for what he has put his body through for science.
"Tim's antibodies are really quite extraordinary - he taught his immune system to get this very, very broad recognition," he said.
The team are now preparing to test its antivenom cocktail in Australia on dogs who have been bitten by a snake.

How Britain can poach America's top scientists
From the time of Newton, Britain led the world in science. That began to change in 1940, when, with the Battle of Britain raging, Winston Churchill sent the scientist Henry Tizard on a secret mission to America. His objective was to secure financial and industrial help in the fight against Hitler. His currency was British military technology, in particular the cavity magnetron, a device that made it possible to locate the enemy with radar. This wowed the Americans and achieved his objective. According to one historian, it was 'the most valuable cargo ever brought to [America's] shores.' While this was a hand-over of scientific power, it catalysed the Anglo-American scientific alliance, which has seen a flow of talent ever since between our two nations. At times there have been concerns that this might be one-way traffic: from us to them.

Swapped at birth: Why dad never looked like his parents
Matthew's dad had brown eyes and black hair. His grandparents had piercing blue was a running joke in his family that "dad looked nothing like his parents", the teacher from southern England turned out there was a very good reason for father had been swapped at birth in hospital nearly 80 years ago. He died late last year before learning the truth of his family - not his real name - contacted the BBC after we reported on the case of Susan, who received compensation from an NHS trust after a home DNA test revealed she had been accidentally switched for another baby in the News is now aware of five cases of babies swapped by mistake in maternity wards from the late 1940s to the say they expect more people to come forward driven by the increase in cheap genetic testing. 'The old joke might be true after all' During the pandemic, Matthew started looking for answers to niggling questions about his family history. He sent off a saliva sample in the post to be genealogy company entered his record into its vast online database, allowing him to view other users whose DNA closely matched his own."Half of the names I'd just never heard of," he says. "I thought, 'That's weird', and called my wife to tell her the old family joke might be true after all."Matthew then asked his dad to submit his own DNA sample, which confirmed he was even more closely related to the same group of mysterious family started exchanging messages with two women who the site suggested were his father's cousins. All were confused about how they could possibly be together, they eventually tracked down birth records from 1946, months after the end of World War documents showed that one day after his father was apparently born, another baby boy had been registered at the same hospital in east boy had the same relatively unusual surname that appeared on the mystery branch of the family tree, a link later confirmed by birth certificates obtained by was a lightbulb moment."I realised straight away what must have happened," he says. "The only explanation that made sense was that both babies got muddled up in hospital."Matthew and the two women managed to construct a brand new family tree based on all of his DNA matches."I love a puzzle and I love understanding the past," he says. "I'm quite obsessive anyway, so I got into trying to reverse engineer what had happened." An era before wristbands Before World War Two, most babies in the UK were born at home, or in nursing homes, attended by midwives and the family started to change as the country prepared for the launch of the NHS in 1948, and very gradually, more babies were delivered in hospital, where newborns were typically removed for periods to be cared for in nurseries."The baby would be taken away between feeds so that the mother could rest, and the baby could be watched by either a nursery nurse or midwife," says Terri Coates, a retired lecturer in midwifery, and former clinical adviser on BBC series Call The Midwife."It may sound paternalistic, but midwives believed they were looking after mums and babies incredibly well."It was common for new mothers to be kept in hospital for between five and seven days, far longer than identify newborns in the nursery, a card would be tied to the end of the cot with the baby's name, mother's name, the date and time of birth, and the baby's weight."Where cots rather than babies were labelled, accidents could easily happen", says Ms Coates, who trained as a nurse herself in the 1970s and a midwife in 1981."If there were two or more members of staff in the nursery feeding babies, for example, a baby could easily be put down in the wrong cot."By 1956, hospital births were becoming more common, and midwifery textbooks were recommending that a "wrist name-tape" or "string of lettered china beads" should be attached directly to the newborn.A decade later, by the mid-1960s, it was rare for babies to be removed from the delivery room without being individually labelled. Stories of babies being accidentally switched in hospital were very rare at the time, though more are now coming to light thanks to the boom in genetic testing and ancestry day after Jan Daly was born at a hospital in north London in 1951, her mother immediately complained that the baby she had been given was not hers."She was really stressed and crying, but the nurses assured her she was wrong and the doctor was called in to try to calm her," Jan staff only backed down when her mum told them she'd had a fast, unassisted delivery, and pointed out the clear forceps marks on the baby's head"I feel for the other mother who had been happily feeding me for two days and then had to give up one baby for another," she says."There was never any apology, it was just 'one of those silly errors', but the trauma affected my mother for a long time." Never finding out Matthew's father, an insurance agent from the Home Counties, was a keen amateur cyclist who spent his life following the local racing lived alone in retirement and over the last decade his health had been deteriorating. Matthew thought long and hard about telling him the truth about his family history but, in the end, decided against it. "I just felt my dad doesn't need this," he says. "He had lived 78 years in a type of ignorance, so it didn't feel right to share it with him."Matthew's father died last year without ever knowing he'd been celebrating his birthday a day early for the past eight then, Matthew has driven to the West Country to meet his dad's genetic first cousin and her daughter for all got on well, he says, sharing old photos and "filling in missing bits of family history".But Matthew has decided not to contact the man his father must have been swapped with as a baby, or his children – in part because they have not taken DNA tests themselves."If you do a test by sending your saliva off, then there's an implicit understanding that you might find something that's a bit of a surprise," Matthew says."Whereas with people who haven't, I'm still not sure if it's the right thing to reach out to them - I just don't think it's right to drop that bombshell."

D-Day landings boosted by import of ‘wonder drug' to Britain, archives reveal
Production of the antibiotic penicillin had struggled to take hold at a large scale in Britain, despite being discovered in 1928 in London by Sir Alexander Fleming. Attempts to produce substantial quantities of medicine from the bacteria-killing mould had not been achieved by the start of the Second World War. Then prime minister Sir Winston Churchill became increasingly frustrated that Britain had not been able to produce enough penicillin in the preparations for the Normandy landings in 1944. Official papers released by the National Archive – containing handwritten notes by Sir Winston – highlight efforts to boost quantities of the antibiotic, with Britain eventually forced to import it from America. The documents were released ahead of the 81st anniversary of D-Day, the Allied invasion of Normandy on June 6, 1944. Official papers highlight the efforts to boost quantities of penicillin (The National Archives/PA) In one report on February 19, after the issue had been raised in the House of Commons, Sir Winston scrawled in red ink on a Ministry of Supply report noting the Americans were producing greater quantities: 'I am sorry we can't produce more.' On another paper, he complained: 'Your report on penicillin showing that we are only to get about one tenth of the expected output this year, is very disappointing.' Elsewhere in the same file he instructs: 'Let me have proposals for a more abundant supply from Great Britain.' With preparations for D-Day ramped up, efforts to deliver enough American-made penicillin for frontline military personnel soon became a matter of urgency. Decisions needed to be made on the quantities of antibiotic imported, how much to administer to individual patients, and how to get medical staff trained in time. Most British doctors did not know how to issue penicillin – until this point, doctors had nothing available to treat infections like pneumonia and many people died of blood poisoning after minor injuries because no drug existed that could cure them. Royal Navy D-Day veteran John Dennett, 101, at the British Normandy Memorial in Ver-sur-Mer to mark the 81st anniversary of the landings (Gareth Fuller/PA) Early in January 1944, Prof FR Fraser, the Ministry of Health's adviser on the organisation of wartime hospitals, wrote that 50,000-100,000 wounded could be expected from the Second Front. He proposed the Emergency Medical Services might need as many as five billion units of penicillin per month for this. Further documents show discussions on whether the antibiotic should be supplied as calcium or sodium salts, or in tablet form. Ultimately, it was agreed powdered calcium salts would be issued for superficial wounds and sodium salts for use in deep wounds. On May 24 1944, less than a fortnight before D-Day, Prof Fraser reported: 'Sufficient supplies of penicillin are now available for the treatment of battle casualties in EMS hospitals, but not for ordinary civilian patients.' Plans were made for casualties from the frontline in France to be brought back to coastal hospitals in Britain for treatment. A week before D-Day, on May 30 1944, hospitals were instructed to treat battlefield patients en route: 'In an endeavour to prevent the development of gas gangrene and sepsis in wounds the War Office have arranged for the treatment of selected cases by penicillin to be commenced as soon after injury as possible.' Military reenactors watch the sunrise over Gold Beach in Arromanches-les-Bains, Normandy, on the 81st anniversary of the D-Day landings (Gareth Fuller/PA) Injections of penicillin were to be given to them at intervals of not more than five hours and patients would be wearing a yellow label with the letters 'PEN'. The time and size of penicillin doses should be written on it, they were told. Dr Jessamy Carlson, modern records specialist at the National Archives, said: 'File MH 76/184 gives a glimpse into the extraordinary levels of preparation undertaken in advance of the D-Day landings. 'Only six weeks before, penicillin is just reaching our shores in quantities which will allow it to play a major role in improving the outcomes for service personnel wounded in action.' As Allied forces made inroads into Europe, restrictions on the use of penicillin for civilians began to relax, but only in special cases. In July 1944, Ronald Christie, professor of medicine, wrote to Prof Fraser to tell him: 'The War Office approves of American penicillin being used for medical conditions in service patients and for air raid casualties among civilians.' On the home front, demand for the new 'wonder' drug began to increase, according the National Archives. It was decided that penicillin for civilians should only be supplied to larger hospitals where the staff had been properly trained to administer it. Only in 1946 did it become fully available for the general public.
