Butterfly Network Advances AI-Powered Aortic Valve and Aorta Screening with New Research and Training Tools

BURLINGTON, Mass. & NEW YORK--(BUSINESS WIRE)--Butterfly Network, Inc. (NYSE: BFLY), a digital health company transforming care with handheld, whole-body ultrasound and intuitive software, today announced its role in new research demonstrating the potential for machine learning (ML) models to support early detection of aortic stenosis (AS) using handheld ultrasound devices. The study, conducted by Tufts Medical Center and published in European Heart Journal – Imaging Methods and Practice, demonstrates that a ML model fine-tuned for use on Butterfly iQ+ devices can achieve high accuracy in identifying AS. The findings support the value of ML model development, and ultimately, are a positive step toward portable screening for earlier detection of this life-threatening condition. Aortic stenosis, a narrowing of the aortic valve, affects over 13% of Americans over 75 years old and is often missed until it's advanced and symptomatic. Studies(1, 2) suggest that a significant number of AS cases remain undiagnosed, particularly among underserved and aging populations. This delay in diagnosis is associated with higher risk procedures, worse outcomes, and increased healthcare costs. As earlier identification and treatments of AS are increasingly associated with better patient outcomes, the need for upstream, accessible screening is critical. 'This research shows a promising path forward where lower-level providers, not just cardiologists or trained sonographers, could screen for aortic stenosis using AI-assisted handheld ultrasound,' said Dr. John Martin, co-author of the study and Butterfly's Chief Medical Officer Emeritus. 'This opens the door to early detection in a wide variety of care venues including primary care offices, long term care facilities, urgent care facilities and even in the home.' The study validated that an ML model trained on hospital-grade ultrasound images performed well when adapted to Butterfly's handheld ultrasound device. After fine-tuning the final layer of a neural network, researchers achieved an area under the receiver operator characteristic curve (AUROC) of 0.94 for differentiating between no aortic stenosis and any degree of aortic stenosis on handheld ultrasound images – a level of accuracy that supports potential clinical use in screening workflows. In a related development, Butterfly has just released the latest expansion of its Butterfly ScanLab™ AI-powered ultrasound education app: an Aorta Exam Protocol. This educational app harnesses animations, anatomical labeling, and a quality indicator to help teach users how to scan the abdominal aorta and recognize normal anatomy. With that training, users can then use POCUS to detect life-threatening conditions like abdominal aortic aneurysms (AAA) and dissections. Designed for ease of use on an iPad, the module is included in every Butterfly membership and compatible with existing Butterfly probes. Joseph DeVivo, President, CEO, and Chairman of Butterfly Network concluded, 'Early detection saves lives, but access to imaging remains a major barrier. This work is about democratizing diagnostics. With AI and education working hand in hand, we're empowering more providers to deliver proactive care in places that were never possible before.' About Butterfly Network Butterfly Network, Inc. (NYSE: BFLY) is a healthcare company driving a digital revolution in medical imaging with its proprietary Ultrasound-on-Chip™ semiconductor technology and ultrasound software solutions. In 2018, Butterfly launched the world's first handheld, single-probe, whole-body ultrasound system, Butterfly iQ. The iQ+ followed in 2020, and the iQ3 in 2024, each with improved processing power and performance by leveraging Moore's Law. The iQ3 earned Best Medical Technology at the 2024 Prix Galien USA Awards, a prestigious honor and one of the highest accolades in healthcare. Butterfly's innovations have also been recognized by Fierce 50, TIME's Best Inventions and Fast Company's World Changing Ideas, among other achievements. Butterfly combines advanced hardware, intelligent software, AI, services, and education to drive adoption of affordable, accessible imaging.

The global AI contest hits the UN

With help from Aaron Mak The rivalry between the United States and China over who will dominate artificial intelligence has moved to an obscure battlefield: A Geneva-based United Nations agency most people have never heard of. The Trump administration announced in June — a full year early — that it will push for a second term for American diplomat Doreen Bogdan-Martin as secretary general of the International Telecommunication Union, the organization that sets voluntary international standards for technology ranging from radio frequencies and broadband to 6G mobile phones. This is the earliest the State Department has ever made this kind of push at the ITU, an indication of the growing urgency of the U.S.-China technological rivalry. The Trump AI Action Plan, released earlier this month, specifically names the ITU as key to America's global tech dominance. But some observers worry that Trump's tough-minded foreign policy approach may already be hurting the U.S. in its quest to keep Bogdan-Martin in office. The ITU has been a great-power battleground before. In 2022, with Huawei turning telecom into a global contest, America and China waged a proxy battle for control over the agency. The Chinese backed Russian candidate Rashid Ismailov, a former Russian telecom minister who lost decisively to Bogdan. Government and tech insiders say the stakes are even higher now because the ITU is setting standards for AI —more than 150 to date — for how governments and countries integrate the technology across existing operations. That's included standards for testing and evaluation of AI systems in areas like conversational AI tools and computer network diagnostics. So whoever controls the ITU will shape the global standards for AI development and integration. Founded more than 150 years ago to standardize telegraph systems, the ITU today includes the U.N.'s 193 members along with representatives of corporations including AT&T, China Unicom, Nokia and Sony. Over the years, the agency has become central to the growth of telecom technology, negotiating international agreements on everything from radio spectrum allocations to the orbital paths of satellites in outer space. ITU added AI to its suite of technologies with the launch of its AI For Good program in 2017. U.N. members vote every four years to select the agency's secretary general, and that vote has grown more loaded each election. Bogdan-Martin's predecessor, China's Houlin Zhao, developed a reputation among Americans of using his position to bend the ITU toward Beijing. 'What you saw over and over again was him trying to align the ITU with endorsing Chinese technology and downplaying U.S. complaints about the potential for security breaches by using ZTE or Huawei technology, or endorsing Chinese Belt and Road Initiative telecommunications projects in developing countries,' said Brett Schaefer, an expert on the U.N. at the American Enterprise Institute, and a former member of U.N. General Assembly's Committee on Contributions. The U.S. blacklisted Huawei and ZTE in 2020 as 'companies posing a national security threat'. China's Washington embassy and New York U.N. mission did not answer DFD's questions. Nor did the State Department or Bogdan-Martin. Beijing hasn't announced if it will contest Bogdan-Martin's renomination. In some respects, the U.S. is at the apex of its technological prowess. Nvidia and Microsoft both reached valuations above $4 trillion, making them the wealthiest companies in world history. Trump's AI Action Plan, released in July, is in part a call to keep the U.S. dominant by exporting American technology around the world. Notably, for a White House that rejects much of the world order, it calls for the U.S. to leverage its positions in international bodies, including the ITU. 'Everyone in the world should be using our technology, and we should make it easy for the world to use it,' White House Office of Science and Technology Policy Director Michael Kratsios said last week in Washington. Observers say Bogdan-Martin's early re-entry into the race shows American officials are wary of China's growing influence. Bogdan-Martin easily defeated her rival in 2022, but Mark Lambert, a State Department veteran of the Biden and first Trump administrations, anticipated Bogdan-Martin's rivals would start their campaign ahead of time as well. 'If the Chinese and Russians are crafty, they'll find a like-minded candidate from Africa or Latin America to put forward to line up lesser developed country votes,' said Lambert. Mark Beall, who directed AI strategy in the Pentagon in the first Trump administration, said the U.S. would likely contest China's influence by appealing to the same voters from the lesser developed world, with the early announcement giving 'time to counter potential infrastructure-for-votes deals that some competitors might offer.' Recent signals in the wonky world of global telecom diplomacy may give the U.S. some cause for concern. Daniel Baer, who served as ambassador to the Organization for Security and Cooperation in Europe under former President Barack Obama, said Trump's tariffs and slashing of foreign aid might be alienating potential ITU votes. 'In much of the world, there's probably less interest in doing favors for the United States than there might have been a year ago,' he said. In June, the ITU voted on the location of the agency's World Radio Conference, planned for 2027. Although Commerce Secretary Howard Lutnick pitched Washington to host the confab, members voted instead to hold the event in Shanghai. 'That's not the outcome that the United States wanted,' said Fiona Alexander, a senior telecoms official in the Commerce Department from 2008 to 2019, during both the Obama and Trump administrations. 'We need to get serious. We need to get organized. There's a long-term play in all of these institutions because it's all about coalition building'. Privacy hawks hound the TSA over facial recognition Privacy-minded Senate Republicans are accusing the Transportation Security Administration of interfering with a bill to make airport screenings less intrusive, POLITICO's Benjamin Guggenheim reported Sunday. Senate Commerce Chair Ted Cruz (R-Texas) said he'd delay consideration of the bill last Tuesday, which would have required the TSA to notify passengers of their ability to opt-out of facial recognition scans and put checks on the storage of biometric data collected in the process. The bill was subject to intense opposition from the travel industry, but Republicans also grumbled about the TSA's involvement. When asked if the TSA raised concerns about the bill, co-sponsor Sen. John Kennedy (R-La.) said, 'The short answer is yes; the long answer is hell yes.' He added, 'They're working like an ugly stripper to kill this bill, which tells me we're doing the right thing.' A senior Senate GOP aide also told POLITICO that the 'smears against [the] bill have TSA's fingerprints all over it.' The TSA did not respond to POLITICO's inquiries on the matter. Delta says its AI is not using our data to set prices Delta Air Lines is denying that it uses personal data to set 'individualized' airfares, POLITICO's Alfred Ng reports. The airline made the claims in a letter that the company sent on Friday to Sens. Ruben Gallego (D-Ariz.), Richard Blumenthal (D-Conn.) and Mark Warner (D-Va.), in response to their questions about its pricing practices. Peter Carter, Delta's chief external affairs officer, wrote in the letter, 'Our AI-powered pricing functionality is designed to enhance our existing fare pricing processes using aggregated data.' This response doesn't seem to have allayed the senators' concerns. 'If Delta is in fact using aggregated instead of individualized data, that is welcome news,' Gallego said in a statement. 'But it still begs the question: why did their president brag to their investors about their desire to 'get you the right offer in your hand at the right time'?' Warner wrote in an X post on Friday that 'many questions remain.' post of the day THE FUTURE IN 5 LINKS Stay in touch with the whole team: Aaron Mak (amak@ Mohar Chatterjee (mchatterjee@ Steve Heuser (sheuser@ Nate Robson (nrobson@ and Daniella Cheslow (dcheslow@

Syncing With Your Chronotype Can Maximize Sleep and Productivity

zeljkosantrac/Getty Images Most people acknowledge that there are two types of sleepers in the world—early birds and night owls—but research has shown that there are actually four or more sleep-wake cycles. The time you naturally open your eyes in the morning and doze off in the evening is the individual expression of your circadian rhythm, a.k.a. your chronotype, which also drives when you feel most alert or sleepy throughout the day. Your chronotype is based on natural daily fluctuations in your body temperature and hormones. Generally, body temp rises as daylight increases. Alertness-boosting cortisol also notches upward in the morning, and then levels off and dips as daylight fades, coinciding with your level of mental awareness. As the sun sets, the sleepiness-promoting hormone melatonin replaces cortisol. The exact cadence of this flux varies based on genetics, Jennifer Martin, PhD, spokesperson for the American Academy of Sleep Medicine and professor of medicine at the David Geffen School of Medicine at University of California Los Angeles, tells SELF. The morning larks among us have a faster-ticking body clock, so this whole schedule kicks off earlier, she explains, while the night owls have a slower clock, pushing the pattern later. Most people fall somewhere in the middle. If you sync up your everyday schedule with your chronotype, you could find it easier to get quality sleep and also get things done. Read on to find expert advice for determining your chronotype and using this intel to align your activities with your body's innate rhythm. 3 ways to figure out your chronotype There's debate among researchers about exactly how many chronotypes there are, but Dr. Martin says it's helpful to think of these schedules as a continuum spanning from the earliest-rising larks to the latest-sleeping night owls. You might intuitively know if you have a strong inclination toward one extreme or the other, but sometimes the requirements of work and other daily obligations can overshadow our true preferences. So Dr. Martin suggests thinking about how you act on vacation (when you're not jetlagged). 'If you love staying up late and sleeping in until 10 or 11:00 a.m., you probably have night-owl tendencies,' she says. Whereas, 'if you go on vacation, and you're super excited about a 6:00 a.m. tee time, for example, you're likely a morning person.' To get more precise, you can also take a chronotype questionnaire. The Morningness Eveningness Questionnaire (MEQ) includes 19 questions—about when you'd ideally choose to wake up, do physically or mentally tough work, and go to sleep—and categorizes you as one of five types based on your score: definitely morning, moderately morning, neither type, moderately evening, and definitely evening. Michael Breus, PhD, a clinical psychologist and sleep medicine specialist, also created the popular ChronoQuiz, which assesses both your habits around and feelings about sleep—and groups people into four camps, each named after an animal with similar behaviors: the lions (which are the morning people), the wolves (a.k.a. the night folks), the bears (who fall in between), and the dolphins, who Dr. Breus explains have some 'genetic irregularity' and an erratic sleep pattern that doesn't fit neatly into the other camps. How to optimize your schedule based on your chronotype Sleep within your ideal window. Since chronotype is based on genetics, morning people can't typically sleep in to make up for late nights, and night people can't generally doze off sooner to account for earlier rise times, Dr. Martin points out. So, if your eyes usually open around dawn, do your best to turn in early enough to still clock the recommended seven-ish hours of sleep; and if you tend to stay awake until the wee hours, aim to sleep in late enough to hit that number. This way, you can get ahead of sleep deprivation and the full slate of health detriments that comes along with it. Of course, aligning your sleep schedule with your chronotype can be a struggle with life obligations—especially for the night owls, whose schedules conflict with societal norms around workday start times. In this scenario, do what you can to slide back your wakeup time and minimize the need for brain power before work: prep breakfast, lay out clothes, get a jump on other morning admin in the evenings. For the early birds (and neutral folks), standard work schedules tend to fit more easily. If you find that social and home tasks are creeping into your evenings and nudging your bedtime back, see how you can spread out plans (so you aren't hit with late nights back-to-back) and reallocate to-dos for before-work time. Do mentally challenging tasks during energy 'on' times. If you're a morning type, you don't just rise with the sun—your body's arousal level also peaks early, between 7 and 10 a.m.; whereas, nighttime types hit max alertness around 7 to 10 p.m., Cindi May, PhD, a professor of psychology at College of Charleston who studies chronotypes, tells SELF. Her research suggests your brain is also primed to do its best work during your respective 'on' period, particularly if you have a strong chronotype. That doesn't apply to every task. 'If you're using a highly practiced skill or rote responses, then you're probably going to be fine whenever,' she says. 'But if you are engaged in a task that requires analytic thinking or attention to detail, that demands that you filter out distraction in order to pay attention, then you'll likely perform best during your optimal zone.' These include activities like making a decision or having a tough conversation, recalling things, reasoning through a complex problem, or weighing the pros and cons of an idea. Practically, it can help to think of the day in two chunks: Morning types tend to experience their most productive hours in the first half of the day, and nighttime types, in the back half, Dr. Martin says. Neutral types can flex a bit in either direction. That said, there's generally an 'off' time for everyone, Dr. Martin says, which tends to fall around 2 to 4 p.m. All chronotypes may lose some alertness in this window, triggering difficulties with creativity and concentration. It's an ideal time for a nap or lower-lift tasks. Eat on a consistent schedule. The optimal timing of meals and snacks depends on your lifestyle and energy needs—but sticking to the same pattern each day (whatever it may be) is a boon for your circadian rhythm, Dr. Breus says. It's more important to eat your first meal of the day at a consistent time that aligns with your internal clock, say, shortly after you wake up, rather than at a specific hour on the wall clock, Dr. Martin says. Also, aim to wrap up eating a couple hours before your bedtime, Dr. Breus adds, as the workings of digestion could interfere with sleep efficiency and quality. Can you change your chronotype? Experts say it's not possible to switch your chronotype. Your genes are your genes, after all. But while your underlying tendency is set, there are things that can shift your sleep-wake schedule a bit on a given day. If you're a night owl and want to wake up and feel alert sooner, bathing your eyes in light first-thing can help get your daytime hormones flowing, and limiting light in the evening can kickstart the nighttime ones, Dr. Martin says. Vice versa if you're an early bird who wants to push your rhythm back: Avoid light for the first couple hours of your day, and get lots of it later on. Another potential chronotype-adjuster is exercise. Research suggests a dose of physical activity in the morning or afternoon can move your schedule up—so if you're a night owl, working out in the first part of the day could help you conk out earlier. By contrast, doing some movement in the back half of the day may delay your circadian rhythm a bit, which could benefit early birds who are looking to stay awake later into the night. If you're thinking, Doesn't caffeine have this effect, too?, you should know: It mostly masks sleepiness or grogginess, which may temporarily improve your focus, memory, and physical performance when you're running low on sleep, Dr. May says. But there's no evidence to suggest consuming it in the morning could move your circadian rhythm up. If anything, it's been shown to delay that schedule, which could make it even tougher for caffeine-gulping night owls to fall asleep at a reasonable hour. More broadly, caffeine can tamper with the quality of your sleep and make it less restorative, so relying on it to wake up earlier or stay up later than your norm isn't a great long-term strategy. Ultimately, unlocking an ideal schedule comes down to respecting your personal energetic cadence, Dr. Martin says. But for some people—like those with extreme chronotypes or ones that clash with their obligations—it can be super tough to get on track. If that's you, she says, it's best to reach out to a sleep specialist, who can offer targeted therapies to help match your sleep-wake pattern to the structure of your life (or the other way around).
