The CH-53 Sea Stallion helicopter's rotor blades contain a spar filled with pressurized nitrogen gas, which leaks out if a crack forms, causing a visible barber-pole indicator to shift as a ground-check warning. Because engineers in the 1960s couldn't rely on wireless electronics surviving inside a spinning rotor head, they developed IBIS, an Inflight Blade Monitoring System that uses a small radioactive source within the same pressure indicator to alert pilots mid-flight if a blade is failing.
The performance coach who works with world No. 1 tennis player Aryna Sabalenka argues that popular productivity techniques break down when real pressure hits. Drawing on personal experience surviving on the streets as a teenager, he contrasts the mindset of a 'warrior' with that of a 'fighter' as the key to performing under stress. He says he has seen conventional advice fail repeatedly across sports arenas, corporate settings, and his own life.
A solo game developer has taken on publishing as a side project, tracking down the rights holder to bring the out-of-print book 'Professor Mmaa's Lecture' back into circulation. The developer negotiated rights, drafted a contract using the Authors Guild's model agreement as inspiration (with help from Claude AI), and corrected Amazon's mistaken assumption that the book was public domain.
An Inside Higher Ed analysis found at least 16 nonprofit colleges shut down in 2025 due to falling enrollment and financial strain, following 28 degree-granting institutions that closed in the first nine months of 2024 alone, according to Hechinger Report data. Entrepreneur's coverage argues these closures are not isolated incidents but the culmination of years of compounding pressures — declining tuition revenue, rising costs, debt and accreditation issues.
Anker's eufyMake brand is developing a new consumer printer that applies designs directly onto fabrics like T-shirts, jeans, bags, and hats. The device supports both direct-to-garment printing and direct-to-film transfers via heat press, and can even add color to single-color embroidered stitching. Pricing and an official product name have not yet been announced.
Huawei has unveiled the Watch D3, a smartwatch that monitors sleep and exercise like typical wearables but stands out for its built-in blood pressure sensor. Instead of relying on optical estimation methods common in other smartwatches, the device inflates a small cuff mechanism on the wrist to take a more direct pressure reading.
Huawei has rolled out three new smartwatch lines alongside a fresh pair of earbuds. The Watch GT 7 series focuses on outdoor sports with ski and snowboard tracking, resort maps, and group location sharing, while the Watch D3 expands to 24-hour ambulatory blood-pressure monitoring. The Watch 6 series adds over 100 workout modes and eSIM calling, and the FreeBuds Neo bring up to 30dB adaptive noise cancellation with lossless and spatial audio support.
South Korean officials have dismissed a House Judiciary Committee GOP report accusing them of unfairly targeting Coupang, the Seattle-based e-commerce firm often called Korea's Amazon, over a data breach. The report followed South Korean hearings, threats of criminal charges against Coupang's interim CEO, and a record data-privacy fine, actions Coupang says were disproportionate to what it calls a minor breach. Congressional sources and people close to Coupang tell CNBC the standoff is now souring US-South Korea relations and could trigger retaliatory measures.
The Haiku operating system project has shipped R1/beta6, its first beta release in roughly two years, arriving just after the open-source project marked its 25th anniversary. The release includes updated documentation covering release notes and press inquiries, and is available as a fresh download or as an upgrade path for existing installations.
Whoop's top-tier Life membership, priced at $359 annually, distinguishes itself mainly through two features: an ECG capable of detecting atrial fibrillation signs and expanded cardiovascular and blood pressure monitoring. The company cautions these tools aren't meant for users with arrhythmias other than AFib, positioning the tier as a niche option rather than a mass-market upgrade.
US electricity demand climbed about 1.7% annually from 2020 to 2025, more than ten times the growth rate utilities saw in the prior fifteen years, driven by data centers, EV charging stations and reshored manufacturing. Much of the transmission network carrying that load dates to the 1950s-1980s, causing sagging lines, overheating transformers and voltage drops as usage climbs.
An entrepreneur behind more than 22 companies at DRC Ventures argues that corporate values only matter when tested by hard trade-offs, not when displayed as slogans. He describes turning mission statements into operational filters that guide daily decisions on suppliers, partnerships and deals, even when a less principled option would be easier or more profitable.
