Scientist Issues Warning of Major West Coast Earthquake
Tina Dura, a geosciences professor at Virginia Tech, was the lead author of a recent study that looked into the risk of major flooding in Washington, Oregon, and Northern California. The study looked into flooding that would be caused from two factors happening together: powerful earthquakes and rising sea levels due to climate change.
Dura and other experts have begun to worry about "the next big event being imminent" in the Cascadia subduction zone, which stretches from Northern California to Washington, given that a major event has not happened in over 300 years.
"We expect something like the Japan 2011 and Sumatra 2004 earthquakes and tsunamis to occur there," Dura told Accuweather.
In an email to Newsweek, Dura clarified that such an earthquake could come "tomorrow or decades from now," but it's "well within the window of possibility."
"But geologically speaking, we're well within the window of possibility. The last event was in 1700, and paleoseismic records show these earthquakes recur roughly every 200 to 800 years," she told Newsweek.
"The National Seismic Hazard model shows that there is a 15% chance of a large (over magnitude 8) earthquake happening sometime in the next 50 years.
"By 2100, there is a 30% chance of a large earthquake happening. To me, those probabilities are high enough that we should be preparing for the effects of such an earthquake."
The Cascadia Subduction Zone is a fault line where the Juan de Fuca tectonic plate is slowly sliding beneath the North American plate.
As Newsweek explains, the boundary between the two tectonic plates is capable of producing megathrust earthquakes that strike with little warning, impacting hundreds of miles of coastline simultaneously, which could trigger widespread land subsidence, powerful tsunamis, and long-lasting infrastructure failures.
Based on the warnings from Dura and other experts, it sounds like this type of earthquake could strike at any time.

Mom Gets All Kids Tested For Daughter's Rare Illness, Worst Fear Comes True
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. When a Long Island toddler was first diagnosed with a rare illness, her family could never have predicted what it would lead to for her older sister. Lisa Superina could tell her daughter Nora was not well from as early as 5 months old. All of her experience as a mother of five told her something wasn't quite right. "She was eating well but often seemed uncomfortable and she wasn't gaining weight," Superina told Newsweek. "She had frequent infections – respiratory and skin. Bad eczema. Her stools were excessive, loose and pale. She seemed very weak with bags under her eyes." Yet despite this, it took time for Superina to get answers. "Nora had genetic testing that all came back negative, so at that point I was told to wait and see what happens," she said. "That was not an option for me... I needed answers. She was my 4th child, so I knew that she wasn't developing typically and something was very wrong." Lisa Superina, her husband and their 5 kids. Lisa Superina, her husband and their 5 kids. Lisa Superina After pushing for more testing, Nora underwent genome sequencing. That was when it was discovered she had Shwachman–Diamond Syndrome (SDS), a rare, inherited bone marrow failure characterized by a low number of white blood cells, poor growth due to difficulty absorbing food, and, in some instances, skeletal abnormalities. Children with SDS can develop blood disorders such as myelodysplastic syndrome (MDS) or leukemia. According to the Boston Children's Hospital, nearly 5 percent of children with SDS develop leukemia, with that risk increasing to 25 percent by adulthood. "This risk goes up with age, so every year gets a little scarier," Superina said. Nora was diagnosed in June 2021, when she was just 15 months old. The rare nature of her illness meant it was not on any doctors' radars when she first began to exhibit symptoms. There would be one more bombshell to come, though. "We were told to test our other children because sometimes SDS is exclusive to the blood and bone marrow and does not have many obvious symptoms," Superina said. A few months later, their worst fears were realized when it was confirmed that Nora's older sister, Kayla, who was just 3 at the time, also had SDS. Though it was a shock to hear, Superina felt some sense of relief that they finally knew about Nora's condition and had uncovered Kayla's before anything bad happened. "I'm so grateful for their diagnosis because it gives us the tools we needed to help them and be proactive," she said. "We know what we are up against." What they are up against is an illness with no known cure, only what Superina describes as "aggressive management." "Nora and Kayla have annual bone marrow biopsies to check for changes or mutations in the marrow that would suggest problems," Superina said. "They get bloodwork every 3 months with hematology at the bone marrow/oncology clinic and see many specialists including hematology, gastroenterology, endocrinology, rheumatology, dermatology, ophthalmology, the list goes on..." It's an experience that has brought the sisters even closer together. "Kayla and Nora have an amazing bond. They support each other for all their appointments... holding hands. Cheering each other on," Superina said. "I definitely think it's made them closer. They don't ever have to go through anything alone- and they always have someone who truly understands." In the meantime, Superina has turned to social media, sharing her daughters' story on Instagram under the handle rarelifemom in the hopes of spreading awareness about SDS and raising essential funds for researching treatments. "I am in touch with top researchers and attended the recent SDS Congress in Cincinnati to learn about the research right now and have been spreading the word for funding a very exciting and promising gene editing project out of Boston Children's with the SDS Registry," she said. "The problem is rare diseases like SDS don't get the funding that more common ones do. So even if we know how to cure it, and have a treatment plan, the money just isn't there. It's often up to the parents and the rare disease community to fund their disease. So that's what I'm trying to do. Raise awareness on social media and who knows, maybe someone with a big heart and a big wallet will see it and want to help my sweet girls."

'Disabling' Chronic Illness in Children Not Taken Seriously: Experts
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. A new study by Rutgers University has highlighted that a significant number of young children are experiencing ongoing symptoms after COVID-19 infection, signifying that greater research needs to be poured into evaluating the risk and treatment of long COVID in children. The study, released on July 23, coincides with Pediatric Long COVID Awareness Week, running from July 21 to 25, run by the advocacy group Long Covid Families. Over the course of the week, the group has been bringing together families, clinicians, researchers, and advocates to raise more awareness on the wide-reaching impact of long COVID in children. "This is a public health crisis for children. And it demands action," Long Covid Families said in its promotion of the condition's awareness week. "Because people operate under the false assumption that if you are young and healthy, like kids, COVID is an inconsequential nothingburger and we should not worry about it," Dr Ziyad Al-Aly, a professor of medicine at Washington University in St. Louis, told Newsweek. "Of course, this is not accurate at all," he added. Long COVID in children "always demanded more attention and seriousness." File photo: a young girl is unwell lying in bed with a teddy bear. File photo: a young girl is unwell lying in bed with a teddy The Study Found The study assessed 1,011 children, of whom 472 were aged 2 or younger, and 539 were aged between 3 and 15. It was found that 101, or 15 percent, of the 677 children who had previously tested positive for SARS-CoV-2 infection were identified as likely having long COVID. Long COVID is recognized as symptoms and health complications following COVID infection that persist for several weeks or months after the initial infection. It can result in a wide range of symptoms, affecting multiple systems in the body. Co-author of the study, Lawrence Kleinman, who is also chair of the Department of Pediatrics at Rutgers University, told Newsweek that he was not "surprised by these findings and would not be surprised to learn in the future that they understate the prevalence of long COVID." Previous studies estimated the prevalence of long COVID in children to be between 10 and 20 percent—suggesting it has become one of the most common chronic illnesses in children. Asthma, often described as the most common chronic illness in children, affects 16 percent. "Our methods were designed to be conservative, that is to maximize the likelihood that we distinguished long COVID from other causes," Kleinman said. "That means that our estimates are likely to be lower than the actual rate of long COVID." "At the beginning of the pandemic, no one knew that long COVID existed," he added. The first reports from China included" inaccurate reports" that children were spared COVID, he said, adding that the reports "grew into a myth which in turn created a mindset that COVID in kids didn't matter." As a result, there "was a misconception that children could not get COVID - but we know that's not true," Melissa Stockwell, another author of the study and chief of the Division of Child and Adolescent Health at Columbia University, told Newsweek. "We are still very behind in raising awareness about long COVID in children," she added. Another reason why long COVID was not taken seriously in children is that "the symptoms associated with long COVID in children were not properly defined," Dr. Akiko Iwasaki, director of the Center for Infection and Immunity at the Yale School of Medicine, told Newsweek. She added that the study underscored "the need for the society to take long COVID in children seriously." However, Dr. Gerald Teague, a professor of pediatrics at the University of Virginia School of Medicine, told Newsweek that the study's investigators "did not confirm COVID infection with diagnostic tests nor did they measure antibodies to COVID in the participants," which would have provided a more accurate screening of the condition. He also noted that children not flagged as having COVID in the study may have had "asymptomatic infection." Although, despite some concerns, he said, with the study, that it was a "proof of concept that long COVID may be a bigger problem than we thought." The Impact Of Long COVID On Children "There is great concern for the younger generation, both about the long-term impacts of the pandemic itself, but also for those with Long Covid," Stockwell said. Long COVID in children can manifest in a number of different symptoms, ranging from "annoying to disabling," Kleinman said. The chronic illness can cause "pain, distress, or disability" in children, directly impacting the child's interaction with their family and friends, and may "hurt school performance, athletic performance, or even the capacity of children to conduct normally routine activities," he added. These factors are of great concern, Al-Aly said, as "we worry about kids' educational attainment, forming friendships, sports, and others, and all of these facets of normal development could be impaired in long COVID." "This may negatively affect kids in their most formative years—leaving them scarred for a lifetime," he added. Long COVID can leave some children bedbound for years, Iwasaki said. "If you have ever spoken to a parent of a child with long COVID, you quickly learn how devastating it can be to the lives of the children and their family," she added. What Experts Think Should Be Done One key part of tackling the issue is down to "improving vaccine uptake," Al-Aly said. However, the Trump administration has recently removed COVID vaccines from the Centers for Disease Control and Prevention (CDC) recommendation for healthy children and pregnant women, as part of Health Secretary Robert F. Kennedy Jr's "Make America Healthy Again" (MAHA) campaign. Kennedy Jr, a well-known vaccine sceptic, said, when announcing the update on X: "It's common sense and it's good science." Another important step is increasing understanding, Stockwell said. "We really need pediatricians to understand what long COVID looks like in children and understand that symptoms are actually different in different-aged children as well," she added. Treatments are the next vital step, Kleinman said. "We need to develop and identify effective treatments for long COVID in a rapidly iterative and long-term approach to quickly identify promising treatments and to evaluate their effectiveness and safety in practice." That treatment, though, needs to "get at the root causes of the disease," Iwasaki said. She added that long COVID is a disease "driven by the virus and the host responses to the virus involving the immune, neurological, cardiovascular, gastrointestinal and pulmonary systems." From a policy perspective, "flexible attendance at school, proper training of teachers and pediatricians, insurance coverage and more funding for research" would all help tackle the issue, Iwasaki added. More broadly, supporting children with long COVID and preventing further cases will require "investment in health and health care services, physical and occupational rehabilitation, and mental health services," Kleinman added, saying this "will be critical for the population health of our children for the foreseeable future."

Smart Speakers Like Alexa and Google Assistant Could Tell if You Have Parkinson's
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. A new AI-powered, speech-based screening tool could help people assess whether they are showing signs of Parkinson's disease at home. Developed as part of a study by University of Rochester computer scientists, the web-based test asks users to recite two pangrams, short sentences using every letter of the alphabet. In just seconds, the AI can analyze the voice recordings to look for subtle patterns linked to Parkinson's—with nearly 86 percent accuracy. The researchers believe such a tool could be implemented as a feature in popular speech-based interfaces like Amazon Alexa or Google Home (with users consent). Parkinson's is typically diagnosed by specially trained neurologists through a combination of examinations, brain imaging and family history. While the new tool is not intended to be a replacement for a clinical diagnosis, the researchers see it as a fast, low-barrier and accessible way to flag people who might have the disease and encourage them to seek thorough clinical evaluation. Man connecting Alexa-like device to phone at home. Man connecting Alexa-like device to phone at 1.1 million people in the U.S. are living with Parkinson's disease, expected to rise to 1.2 million by 2030, according to Parkinson's Foundation. Nearly an estimated 90,000 people are diagnosed across the country each year, making it the second-most common neurodegenerative disease after Alzheimer's. While incidence increases with age, some four percent of people are diagnosed before 50. "There are huge swaths of the U.S. and across the globe where access to specialized neurological care is limited," said Rochester computer science professor Ehsan Hoque in a statement. "With users' consent, widely used speech-based interfaces like Amazon Alexa or Google Home could potentially help people identify if they need to seek further care." Most people living with Parkinson's in the U.S. seek their care from neurologists, with approximately 50 percent seeing a community neurologist and 9 percent seeing a movement disorders specialist, a previous Parkinson's Foundation study found. However, nearly 40 percent of people with the disease do not see a neurologist for their care but see a primary care provider (29 percent) or no provider (11 percent.) Home speaker device. Home speaker device. fabioderby/Getty Images To train and validate the new tool the researchers collected data from more than 1,300 participants—with and without Parkinson's—across home care settings, clinical settings at the University of Rochester Medical Center and the InMotion Parkinson's disease care center in Ohio. Using their computer's microphone, participants were asked to read aloud the following sentences: "The quick brown fox jumps over the lazy dog. The dog wakes up and follows the fox into the forest, but again the quick brown fox jumps over the lazy dog." By utilizing advanced semi-supervised audio models trained on millions of digital recordings to understand the characteristics of speech, the tool can obtain enough vocal cues from the short sentences to flag warning signs. "For example, the way someone with Parkinson's would utter sounds, pause, breathe, and inadvertently add features of unintelligibility is different in someone without Parkinson's," explained paper author and computer science master's degree student Abdelrahman Abdelkader in a statement. The tool was 85.7 percent accurate when tested, providing a strong indication of whether someone may have Parkinson's, according to the study authors. Woman using Google Nest-like device at home. Woman using Google Nest-like device at well as speech, some people can display signs of Parkinson's through motor movement tasks or facial expressions. Over the past decade, this has led Hoque's lab to pursue algorithms to combine multiple indicators with state-of-the-art results. "Research shows that nearly 89 percent of people with Parkinson's have a deformity in their voice that can be indicative of the disease, making speech a strong starting point for digital screening," said paper author and computer scientist Tariq Adnan in a statement. "By combining this method with assessments of other symptoms, we aim to cover the majority of people through our accessible screening process." An interactive, browser-based demonstration of the lab's three screening tests, including this new speech test, is available to try out at home here.
