Advancements and prospect of safety monitoring, inspection and assessment technologies for oil and gas pipeline networks
As global energy demands rise and pipeline networks expand, ensuring the safety and reliability of oil and gas infrastructure has become a priority. A new review(doi: https://doi.org/10.1016/j.jpse.2025.100267 ) published by Chen Pengchao from the PipeChina Institute of Science and Technology outlines the current developments of pipeline safety technologies around the world, offering suggestions to future development of defect detection, environmental risks monitoring, and structural integrity assessment with unprecedented precision.
'The integration of high-grade steel, large-diameter pipelines, and unconventional energy sources has introduced new complexities to pipeline safety,' explains Chen. 'The research focuses on bridging technological gaps in inspection, monitoring, and fitness-for-service (FFS) assessments to mitigate risks and prevent catastrophic failures.'
Chen highlights significant progress in both in-line and external inspection methods. Advanced in-line tools such as magnetic flux leakage (MFL) and ultrasonic testing devices in Germany, America and China now detect micro-defects in millimeter-scale in high-grade steel pipelines.
'PipeChina's magnetoelectric integrated inspection tool combines ultra-high-resolution sensors to identify weld defects with 90% accuracy for 0.3 mm defects, shares Chen. 'It's a milestone for China's domestically developed technologies.'
Meanwhile, pipeline leaks and geohazards like landslides pose severe threats to infrastructure and ecosystems. 'Real-time data fusion algorithms, integrated with supervisory control systems, allow China to achieve leak detection sensitivity as low as 1% of flow rate, minimizing false alarms,' says Chen.
The review also emphasizes innovations in distributed fiber-optic sensing (DFOS). For geohazard management, advanced tools like satellite-based interferometric synthetic aperture radar (InSAR) and unmanned aerial vehicles (UAVs) provide early warnings of ground displacement near pipelines. 'Combining space-air-ground monitoring with AI-driven risk models allows us to predict geologic hazards and prioritize interventions,' says Chen. 'The future lies in transforming conventional pipelines into intelligent networks by leveraging AI and emerging sensing technologies.'

Foresight Announces Plan for Reverse Share Split
Ness Ziona, Israel, Aug. 15, 2025 (GLOBE NEWSWIRE) — Foresight Autonomous Holdings Ltd. (Nasdaq and TASE: FRSX) ('Foresight' or the 'Company'), an innovator in 3D perception systems, announced today that it plans to conduct a reverse share split of the Company's outstanding ordinary shares, no par value per share, at a ratio of 1-for-7 which is expected to be implemented at market open on the Tel-Aviv Stock Exchange on August 24, 2025 and on the Nasdaq Capital Market on August 25, 2025. There will be no change to the existing ratio of the number of ordinary shares represented by the Company's American Depositary Shares ('ADSs'). However, as a result of the reverse share split, the ADS price is expected to increase proportionally, although the Company can give no assurance that the ADS price after the reverse share split will be equal to or greater than the ADS price on a proportionate basis. The Company believes that the reverse share split will help the Company to maintain compliance with Nasdaq listing requirements. However, the Company can give no assurance that this goal will be achieved. As of the effective date for the reverse share split, the Company's ADSs will continue to be traded on the Nasdaq under the symbol 'FRSX' with a new CUSIP Number. The reverse share split will not impact any shareholder's percentage ownership of the Company or voting power. No fractional new ADSs will be issued in connection with the reverse share split. Instead, fractional entitlements to new ADSs will be aggregated and sold by the Depositary Bank and the net cash proceeds from the sale of the fractional ADS entitlements (after deduction of fees, taxes and expenses) will be distributed to the applicable ADS holders by the Depositary Bank.

Nike Sues Edison Chen For $126 Million USD
CLOTfounderEdison Chenis being sued by former partnerNikefor breach of contract, demanding a sum of more than $126 million USD. Multiple sources, including@SneakerLegalhave shared the information, including the case number (2:25-cv-07447), cause (28:1332 Diversity-Breach of Contract), and the demand of $126,615,000. Other than these details, still little is known about the specific violations and events that led to the escalation. The lawsuit has emerged more than a year after Chen terminated his collaborations with the American sneaker label and began releasing products with adidas, like the CLOT Silk Gazelle and the CLOTAnthony EdwardsAE-1. For years, the CLOT designer worked closely with Nike on various models before partnering with the Three Stripes brand in 2023. In 2004, Chen founded CLOT in Hong Kong and began partnering with Nike in 2006. The brand still maintains special popularity in the Asia Pacific region for its exploration of Eastern heritage and aesthetics, but has become increasingly global thanks to partnerships with sportswear titans. As the brand charges forth with a new CEO at the helm, it seems that it's become more vigilant of its brand universe than ever, targeting direct collaborators like Chen and even designers outside of their direct sphere, likethe Shoe Surgeon. Nike's move to sue Chen comes right after the brand finally settled with the famous custom-sneaker designer, a de-escalation from the $60 million originally demanded. Stay tuned to Hypebeast as more details emerge on the case.

SAN FRANCISCO--(BUSINESS WIRE)-- Modern Health, a leading global workplace mental health platform, today announced the appointments of Chen Cheng as Chief Technology Officer and Erin Brown as General Counsel, along with other company momentum, as it accelerates its mission to make mental health care more accessible, personalized, and effective worldwide. 'Welcoming exceptional leaders like Chen and Erin marks an exciting step forward for Modern Health,' said Matt Levin, CEO of Modern Health. In her role as Chief Technology Officer, Chen Cheng will oversee the company's technology and further scale the platform to provide high-quality, clinically rigorous care across the globe. She brings more than a decade of experience in the health technology sector to Modern Health, including roles at Oscar Health and ZocDoc. As technology plays an increasingly critical role in expanding access to mental health care and support, evidenced by the growing engagement with virtual therapy, coaching, and digital tools, Chen will leverage her tech experience and leadership to help Modern Health advance its innovations. Erin Brown joins Modern Health as General Counsel, bringing more than 20 years of legal experience across the health and benefits space. Brown has amassed a proven track record of guiding high-growth organizations through complex legal and regulatory environments. Prior to Modern Health, Brown was Senior Vice President and Associate General Counsel at Alight Solutions and, before that, Associate General Counsel at Aon Hewitt. Her expertise and strategic counsel will be key as Modern Health continues to expand its global footprint and innovate responsibly in a rapidly evolving industry. 'Welcoming exceptional leaders like Chen and Erin marks an exciting step forward for Modern Health,' said Matt Levin, CEO of Modern Health. 'They each bring a powerful combination of industry expertise and a passion for making mental health care more accessible, personalized, and effective. Their leadership will accelerate our momentum as we scale our impact, drive innovation, and continue delivering meaningful outcomes for the workplaces we support worldwide.' In addition to these appointments, other recent company momentum includes: Modern Health has been named to the 2025 Inc. 5000 list of the fastest-growing private companies in America. The list highlights companies that have demonstrated significant revenue growth over a three-year period and serves as a benchmark for entrepreneurial success and a platform for recognizing the contributions of these businesses to the US economy. Modern Health launches ROI Study that proves mental health care pays off: According to a third-party analysis of 13,000+ members, the most significant savings (60% of total savings) in health care spend for employers come from reaching more employees earlier with support that fits their needs before symptoms escalate. Modern Health's evidence-based Adaptive Care Model delivers an estimated $2.39 return for every dollar invested, based solely on health care cost savings. These compelling findings underscore how Modern Health's Adaptive Care Model improves outcomes and drives down costs by supporting the whole workforce—not just those with severe mental health concerns. Peer-reviewed data shows Modern Health's global mental health model works anywhere: In one of the largest and most diverse real-world studies of its kind, Modern Health examined engagement and clinical outcomes among more than 33,000 members across seven global regions to understand not only how mental health needs vary across regions but also whether a single care model could truly work at a global scale. The study proves that achieving global scale requires more than a one-size-fits-all approach; it demands an adaptive, evidence-based model designed to deliver meaningful results across diverse regions and populations. Modern Health's latest study paints a stark picture of how Gen Z and Millennial employees are faring: In a study of 1,000 American professionals aged 18 to 44, the findings reveal a generation silently struggling under the weight of burnout, financial anxiety, and workplace systems that haven't kept pace with their needs. Among the most striking statistics: 75% blame financial stress for fueling burnout and hurting productivity, 79% sacrifice mental health to meet work demands, and 96% want access to preventative mental health support. The workplace report highlights a troubling reality: too many young workers are quietly pushing through mounting mental health challenges just to keep up at work, underscoring the urgent need to meet people earlier, with care that's proactive, adaptive, and designed to support the mental health of entire workforce populations. Launch of FlexEAP Challenges Outdated Employee Assistance Programs: Modern Health recently launched FlexEAP ('Flex'), a next-gen Employee Assistance Program (EAP) addressing the critical shortcomings of traditional EAPs by delivering rapid access to care, adaptive support extending far beyond crisis intervention, and a seamless, consistent global experience. The product combines Modern Health's Adaptive Care Model with an elite, global provider network to deliver a seamless, personalized mental health experience. Employees can access care, on average, within 24 hours, with fast, frictionless support across therapy, coaching, crisis intervention, and digital self-guided tools. Flex delivers superior outcomes and an upgraded, consumer-grade experience compared to traditional EAPs, while offering flexible pricing, customizable solutions, and risk-sharing based on utilization—empowering employers to better manage costs. Expanded Languages for Pathways: Modern Health is proud to offer its Pathways Collections, offering tailored one-on-one support around a variety of topics, including Workplace Well-being, Family Care, and Physical Well-Being, as a truly multilingual product. Now, members can connect with a Pathway Provider in six additional languages — Spanish, Dutch, Hindi, Portuguese, Japanese, and French.
