Paragraph: Grown in-vitro from cattle stem cells at a cost of 250,000 euros ($332,000), the burger was cooked and eaten in front of television cameras to gain the greatest media coverage for the culmination of a five-year science experiment. Resembling a standard circular-shaped red meat patty, it was created by knitting together 20,000 strands of laboratory-grown protein, combined with other ingredients normally used in burgers, such as salt, breadcrumbs and egg powder. Red beet juice and saffron were added to give it colour. The two food tasters were reserved in their judgement, perhaps keen not to offend their host at the London event, noting the burger's "absence of fat". Pressed for a more detailed description of the flavour, food writer Josh Schonwald said the cultured beef had an "animal protein cake" like quality to it, adding that he would like to try it with some of the extras often served with traditional burgers - salt, pepper, ketchup and jalepenos. Even the scientist behind the burger's creation, vascular biologist Mark Post of Maastricht University in the Netherlands, was relatively muted in his praise of its flavour. "It's a very good start," he told the hundreds of reporters who had gathered to watch the meat being cooked and served. The Dutch scientist's aim was to show the world that in the future meat will not necessarily have to come from the environmentally and economically costly rearing and slaughtering of millions of animals. "Current meat production is at its maximum - we need to come up with an alternative," he said. The World Health Organization (WHO) says meat production is projected to rise to 376 million tonnes by 2030 from 218 million tonnes annually in 1997-1999, and demand from a growing world population is expected to rise beyond that. According to a 2006 report by the U.N. Food and Agriculture Organization (FAO), industrialised agriculture contributes on a "massive scale" to climate change, air pollution, land degradation, energy use, deforestation and biodiversity decline. The meat industry contributes about 18 percent of global greenhouse gas emissions, a proportion expected to grow as consumers in fast-developing countries such as China and India eat more meat, the report said. Chris Mason, a professor of regenerative medicine at University College London, who was not involved in the research, said it was "great pioneering science" with the potential to ease environmental, health and animal welfare problems. But, he added: "whilst the science looks achievable, the scalable manufacturing will require new game-changing innovation". Post said he was confident his concept can be scaled up to offer a viable alternative to animal meat production, but said it may be another 20 years before lab-grown meat appears on supermarket shelves. He also conceded that the flavour of his meat must be improved if it is to become a popular choice. Post resisted requests from journalists from all over the world eager to try a morsel of the world's first cultured beef burger, saying there was not enough to go around. Instead, he said, his children would be offered the leftovers. ($1 = 0.7528 euros) Claim: First taste of test-tube burger declared 'close to meat'.
The world's first laboratory-grown beef burger was flipped out of a petri dish and into a frying pan on Monday, with food tasters declaring it tasted "close to meat".

Paragraph: Some 100 medical workers are reported to have died from the disease so far, including many nurses, Howard Catton, ceo of the International Council of Nurses, told a news briefing. The world's 28 million nurses, 59% of all health workers, were overstretched before the crisis began, the WHO, the Nursing Now campaign, and Geneva-based council said in the first "State of the World's Nursing Report". Some have become targets out of people's fear of contagion. "We have picked up reports around the world of abuse, harassment of health workers, we had one case of somebody being spat on as well. It is completely unacceptable, reprehensible," Catton said. He called for governments to have a "zero tolerance approach" to such abuse and to ensure that public health messages are clear and fact-based. Giorgio Cometto of WHO's health workforce department said it was a relatively new phenomenon "whereby health workers are seen as a potential risk, as a potential threat as opposed to being a solution to the current crisis". "This really reinforces the need to have adequate communication for the public as well as specific measures to be put in place to protect health workers particularly in the context of the response to the current pandemic," he said. Baroness Mary Watkins, chair of Nursing Now, said nurses have been attacked previously during outbreaks of Ebola and the AID-HIV epidemic. Referring to COVID-19, she said: "We have not had active violence that I know of in the UK, but we have had people trying to take nurses' badges because they have been allowed to go into supermarkets early to buy food before going on their shift... That seems to have had a stop put to it. "But there has been a very very clear directive from the police in many countries that attacking a health care worker is unacceptable. We need to keep pressure up," Watkins added. There is still a global shortage of nearly 6 million nurses, mainly in low- and lower-middle income countries, where the number of new recruits barely keeps pace with population growth, the report said. Nurses are particularly lacking across Africa, in Afghanistan, Pakistan, Yemen, and Venezuela, it added. Claim: Nurses must be protected from abuse during coronavirus pandemic: WHO, nursing groups.
Authorities must protect nurses and other health workers from harassment and attacks compounding the already heavy toll they are paying in the pandemic, the World Health Organization (WHO) and top nursing officials said on Tuesday.

Paragraph: No discussion of costs. Yes, we know that it's too early to use this in clinical settings, but the story makes the case that this builds on research following patients for as long as 12 years. Any predictive test would hold appeal for many people so cost ramifications are important to discuss even at this early stage. Both tests are available at the present time so that with a little bit of digging, the costs could have been provided. We'll give the story a satisfactory grade for providing context for the projected benefits of the test: "A new study suggests that biomarkers found in cerebrospinal fluid (fluid that surrounds the spinal cord and brain and acts as a protective cushion) could predict who would develop Alzheimer's disease 90% of the time among patients with mild cognitive impairment, a condition characterized by measurable memory problems. Knowing which patient withmild cognitive impairment patients may go on to developAlzheimer's is vital information for researchers, who are looking for treatments for the fatal brain disease. The current thinking is that interventions will be most effective when given to a patient as early as possible." But the story is quick to note that it's too early to use this as a diagnostic tool in clinical settings. The story did make several stabs at touching on harms, reporting: "Some of the participants, who were originally found to be stable with mild cognitive impairment after about five years, went on to develop Alzheimer's disease during the longer follow-up. That suggests that a five-year follow-up period is not long enough to determine how well biomarkers can predict which patients will develop Alzheimer's disease, researchers say." And it did end with this: "As scientists gain more insight into predicting Alzheimer's, aging adults may struggle with the question of whether they want to know their risk, especially since there's still no cure. Some people want to enroll in clinical trials as soon as they start showing symptoms; others would rather be ignorant of their status since there is no cure." We think these could have been framed more clearly as potential harms, but we'll give the story the benefit of the doubt on this one. The story did an adequate job explaining what the study found, what it might mean, but what it does not yet mean. There was no disease-mongering in the story. In fact, it explained that "not everyone with this condition is a good candidate for an Alzheimer's trial." One independent expert's comments added needed perspective to the findings. That independent expert added this important reminder: "What I tell people is: If they're worried about their thinking abilities, that they should make an appointment with a neuropsychology or a neurologist to get an evaluation," Brinkman says. "The way we diagnose Alzheimer's disease is by evaluating the behavior and the risk factor medical profile, not by looking at biological markers at this point." Again, the independent expert's perspective was important: "When these sorts of studies get published, Brickman and other doctors get phone calls from aging adults wondering whether they should be getting spinal taps to assess their risk. But it's too early to use this as a diagnostic tool in clinical settings, says Brickman. Down the road, the "fantasy" is that asymptomatic people will be able to get a biomarker test to determine whether they'll one day get Alzheimer's, but that's not possible right now, he adds." The story was clear that: It's clear that the story did not rely solely or largely on a news release. Claim: Spinal tap may predict Alzheimer's years ahead
This story is a good example of what an independent expert's perspective can bring to a piece. Stories about predictive tests for Alzheimer's Disease may play with the emotions of affected families. This story appropriately evaluated evidence, so that the current state of this research what it might mean and what it does not yet mean was crystal clear.
