[Q]: Paragraph: Health Minister Olivier Veran told a briefing he could not determine at this stage when the lockdown would end. If the government were to follow the scientific council’s advice, France would remain at a virtual standstill until April 28. A statement by the council, which advises President Emmanuel Macron on the coronavirus crisis, also said the lockdown was the only really efficient strategy at the moment and “needs to be strictly implemented”. Prime Minister Edouard Philippe said on Monday the widespread lockdown in France could last several more weeks and his government was tightening restrictions on daily life even further. Veran also said France would heed World Health Organization recommendations to increase coronavirus testing. Health agency chief Jerome Salomon said later France would soon be able to conduct 10,000 tests a day. Salomon reported 240 new deaths from coronavirus on Tuesday for a total of 1,100, an increase of 28% that made France the fifth nation to cross the 1,000-fatalities threshold after - China, Italy, Iran and Spain. This tally only accounts for people who died in public hospitals, whereas several retirement homes have been reporting deaths in the double digits. Salomon said health authorities would soon be able to tabulate data coming from retirement homes, which will likely trigger a more dramatic increase in registered fatalities. He said the total number of infections in France had risen to 22,300, a 12% jump in 24 hours. Salomon added that 2,516 people were in a serious condition requiring life support, up by 21% from Monday, and that 8,000 hospital beds were now equipped with ventilators. Claim: French coronavirus death toll tops 1,000, lockdown likely to be extended.
[A]: France became the fifth country to report more than 1,000 deaths from coronavirus on Tuesday and a government body dealing with the outbreak suggested the national lockdown imposed last week for an initial 15 days should last at least six weeks.


[Q]: Paragraph: Such a test could initially be used to select patients for clinical trials of experimental treatments being developed to try to halt progression of Alzheimer’s, the researchers said, and may one day move into routine use in doctors’ clinics. “Alzheimer’s begins to affect the brain many years before patients are diagnosed (and) many of our drug trials fail because by the time patients are given the drugs the brain has already been too severely affected,” said Simon Lovestone of Oxford University, who led this work from King’s College London. “A simple blood test could help us identify patients at a much earlier stage to take part in new trials and hopefully develop treatments,” he said. Alzheimer’s is the most common form of dementia, a brain-wasting disease which in 2010 was estimated to be costing the world $604 billion a year. The fatal disease affects 44 million people worldwide, with the number set to triple by 2050, the campaign group Alzheimer’s Disease International says. Several big pharma firms including Roche, Eli Lilly, Merck & Co and Johnson & Johnson, are pursuing various approaches to get to the root cause of Alzheimer’s and try to find treatments to halt its progression. Yet over the past 15 years, more than 100 experimental Alzheimer’s drugs have failed in trial. Lovestone and other experts believe this may be because drug trials are conducted too late, in patients whose condition has already gone too far. A predictive test for use before people develop symptoms would help researchers select the right people for drug trials, and help show whether the experimental drugs are working. Previous studies have found that PET brain scans and tests of lumbar fluid can be used to predict the onset of dementia from people with a less severe condition known as mild cognitive impairment (MCI), but these tests are expensive and invasive, so scientists are keen to develop a cheaper, simpler blood test. MCI includes problems with day-to-day memory, language and attention. It can be an early sign of dementia, or a symptom of stress or anxiety. Around 10 percent of people diagnosed with MCI develop dementia within a year. Apart from regular assessments to measure memory decline, there is currently no accurate way of predicting who will or won’t develop dementia. For this study, published in the journal Alzheimer’s & Dementia, Lovestone’s team used blood samples from 1,148 people - 476 with Alzheimer’s, 220 with mild cognitive impairment and 452 elderly controls without dementia. They were analyzed for 26 proteins previously found to be linked with Alzheimer’s. The team found 16 of these 26 proteins to be strongly associated with brain shrinkage in either MCI or Alzheimer’s and then ran a second series of tests to see which of these could predict which patients would progress from MCI to Alzheimer’s. With this second series, they found a combination of 10 proteins capable of predicting with 87 percent accuracy whether people with MCI would develop Alzheimer’s disease within a year. Experts in the field welcomed the results but said they should be replicated in larger studies before an Alzheimer’s blood test could be rolled out for use in doctors’ clinics. “The results reported today are interesting, but as the authors point out there is still a very large amount of work remaining until a usable blood test for Alzheimer’s disease becomes available,” said Adrian Pini of the MRC Center for Developmental Neurobiology at King’s College London. James Pickett, head of research at the Alzheimer’s Society, said the research “does not mean that a blood test for dementia is just around the corner”. “These 10 proteins can predict conversion to dementia with less than 90 percent accuracy, meaning one in 10 people would get an incorrect result,” he said. “Accuracy would need to be improved before it could be a useful diagnostic test.” Claim: Study paves the way for a blood test to predict Alzheimer's.
[A]: British scientists have identified a set of 10 proteins in the blood that can predict the onset of Alzheimer’s and call this an important step towards developing a test for the incurable brain-wasting disease.


[Q]: Paragraph: It’s widely known that languages evolve as societies develop and change, but the sounds we utter are also shaped, literally, by the placement of our jaw — and that is influenced by how we chew our food, researchers report Thursday in the journal Science. Language study often focuses on cultural factors, “but our work shows that language is also a biological phenomenon — you can’t fully separate culture and biology,” said Balthasar Bickel, a linguist at the University of Zurich and co-author of the new study. The researchers analyzed Stone Age and modern skulls and created simulations of how different jaw placements allow our mouths to make different sounds. They analyzed a database of roughly 2,000 languages — more than a quarter of languages in existence today — to identify which sounds were more and less frequently used, and where. Languages spoken by groups with hunter-gatherer societies in their more recent past are far less likely to use consonants used by longtime farming societies, the study found. “Our anatomy actually changed the types of sounds being incorporated into languages,” Noreen von Cramon-Taubadel, an evolutionary anthropologist at the University of Buffalo who was not involved in the study, wrote in an email. Before societies cultivated crops and learned to cook food, early humans chewed tough raw meat — which was hard work on our jaws and teeth. Stone Age adult skulls don’t look like modern skulls. These older skulls have upper and lower teeth closing directly on top of each other — whereas today most people have some degree of overbite, with the front teeth extending in front of bottom teeth when the mouth is closed. “If you are raised on softer foods, you don’t have the same kind of wear and tear on your bite that your ancestors had, so you keep an overbite,” said Bickel. Eating softer foods not only sets the jaw in a different fashion, but also changes which sounds are easily pronounced. In particular, it becomes much easier to say “f″ and “v,” which linguists call “labiodental” sounds. (Try it. Put your upper and lower incisors — or “front teeth” — directly on top of each other and try say “favor.” It’s difficult.) The researchers looked closely at 52 languages from what is called the Indo-European language group — including dialects spoken from Iceland to India — and charted how the “f″ and “v″ sounds appeared in a rising number of languages over time. As more societies developed agriculture and traded in raw meat for softer fare — whether it’s cooked meat and potatoes, or rice and stewed vegetables — these sounds became more common, the researchers found. “New sounds get introduced into languages, and then are more widely adopted,” said Steven Moran, also a linguist at the University of Zurich and co-author of the paper. The notion that agriculture shaped language was first suggested decades ago by American linguist Charles Hockett, but he did not attempt to prove it. Elan Dresher, a linguist at the University of Toronto who was not involved in the study, commended testing Hockett’s theory, but said the research could be fine-tuned by looking at historical reconstructions of languages, rather than using language databases to make comparisons. ___ The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

[A]:
The way most of us speak today is shaped in part by how long ago our ancestors gave up chewing tough, raw meat.
