SCIENCE AND TECH
The NCES reports that by 2021–22, 96% of public schools provided digital devices to students who needed them and 70% offered some form of internet access outside school.
U.S. school districts are wrestling with building systems that can’t keep pace with present-day health, safety and instructional demands. A Government Accountability Office survey found that about 41% of districts need to replace or update heating, ventilation and air-conditioning (HVAC) systems in at least half of their schools: roughly 36,000 buildings where temperature control and air quality directly affect learning.
At the same time, the CDC has documented uneven progress on ventilation strategies since the pandemic: by 2022, 33.9% of districts reported HVAC upgrades; 28% deployed HEPA-filtered air cleaners; and 8.2% implemented ultraviolet germicidal irradiation.
Ventilation and heat are converging as a facilities challenge. The Center for Climate Integrity estimates that 13,700 additional public schools will need to add air conditioning this decade as heat days rise, at a capital cost on the order of $40 billion of America’s $3.7 trillion infrastructure funding gap.
Ventilation, Attendance and Health
Multiple studies tie ventilation to attendance and student outcomes, independent of income and demographics. A peer-reviewed analysis in the American Journal of Public Health found that higher indoor CO2—often a proxy for insufficient ventilation—correlated with 10%–20% higher absenteeism in K-12 classrooms
The EPA estimates that asthma could account for more than 10.5 million missed school days each year.
Ventilation and filtration upgrades can improve instructional time and health equity.
Device access expanded during and after the pandemic. The NCES reports that by 2021–22, 96% of public schools provided digital devices to students who needed them…

It’s easier than ever to manage parts of your wellbeing with just a few taps. You can order groceries, schedule workouts, track steps, and even have pre-packed meals delivered—all from your phone. Tech has made wellness more accessible in some ways, but it’s also changed how we think about looking after ourselves.
This shift toward convenience has its benefits, but it also raises a simple question: what parts of wellness can’t be handed over to technology? When everything is simplified, it’s worth thinking about what still needs real thought, personal effort, and choice. In this article, we’ll look at how convenience and technology fit into modern wellness—and where they stop short.
Convenience Isn’t a Shortcut for Intentional Choices
There’s no denying that technology has helped people make wellness more manageable. Whether it’s setting a reminder to drink water or scanning ingredients while shopping, tools are everywhere to simplify your day. Convenience, in this context, isn’t necessarily a bad thing—it’s just important to use it with intention.
Some people choose to keep wellness products on hand that align with their needs. This might include easy-to-store snacks, meal shakes, or other wellness items like supplements. For instance, USANA Health Sciences offers a wide range…
In the fast-evolving business landscape, leadership today requires more than sharp decision-making and strategic vision. Executives are under immense pressure to balance operational demands with innovation, team management, and global expansion. This challenge has given rise to a new kind of professional support: the AI-savvy virtual executive assistant.
Far from being limited to administrative tasks, modern virtual executive assistants are now integrating artificial intelligence tools to deliver insights, streamline operations, and help executives focus on what matters most. They are emerging as strategic partners rather than background support, reshaping the way leadership is executed across industries.
From Administrative Help to Strategic Partnership
Traditionally, executive assistants handled scheduling, emails, and general coordination. While those responsibilities remain important, the scope of support has expanded dramatically. Virtual executive assistants, working remotely, now manage not just calendars and inboxes but also project workflows, research, data analysis, and cross-team communication.
The addition of AI tools has further elevated their role. Tasks such as document drafting, report generation, and meeting preparation can now be completed with AI-enabled efficiency. Instead of spending hours creating summaries or searching through files, executives can receive actionable insights quickly and reliably. This means decision-making can happen faster and with greater precision.

Gears may look straightforward at first glance: just teeth cut into a wheel. But anyone who works with them knows the truth is far more complex. The accuracy of a gear goes beyond simple tooth spacing. Tolerances and surface finishes play a critical role in how well a gear meshes, how quietly it runs, and how long it lasts. Overlook them, and the gear may still function, but not for long.
This article explores why tolerances and surface finishes are so important in gear manufacturing, and why they often separate a high-performing component from one that fails prematurely.
Why Gear Accuracy Matters
Gears are the backbone of countless systems, including transmissions, turbines, and industrial gearboxes. Their job is simple in theory: transfer torque and motion from one shaft to another. But if the teeth do not engage smoothly, problems appear quickly. Excessive noise, vibration, premature wear, or even catastrophic breakdowns can all be traced back to inaccuracies.
Tolerances and finishes address this risk. Tolerances ensure the gear is cut within acceptable dimensional limits, while surface finishes dictate how those teeth interact during operation. Together, they define whether the gear delivers smooth power transmission or constant maintenance issues.
Tolerances: Defining the Allowable Error
No manufacturing process is perfect. Even with advanced CNC machines, there are always slight deviations from the design. Tolerances acknowledge this reality by setting the acceptable range of variation.
In gear manufacturing, tolerances cover:
- Tooth thickness and spacing
- Pitch diameter
- Profile accuracy
- Runout and concentricity
These values are not arbitrary. They are defined by standards such as ISO 1328 or…

Groundbreaking research by Boris Kriuk Labs analyzes 3 million observations to map sustainable infrastructure future across warming Arctic
In what represents one of the most comprehensive Arctic scientific studies ever conducted, researchers at Boris Kriuk Labs have developed an advanced artificial intelligence system that identifies which Arctic infrastructure faces catastrophic failure as climate change destabilizes permafrost across northern territories. The study addresses a critical sustainability crisis: over one hundred billion dollars in buildings, pipelines, roads, and industrial facilities built on frozen ground that is rapidly thawing.
Led by Boris Kriuk of Hong Kong University of Science and Technology and Boris Kriuk Labs, the research integrates an unprecedented 3,000,000 observations from 171,000 locations spanning seventeen years, representing approximately twenty times the scale of previous permafrost modeling efforts. The findings reveal that without aggressive climate action, over half of Arctic infrastructure locations will experience severe permafrost degradation within decades, threatening sustainable development across the region.
“Arctic communities and industries face an existential infrastructure sustainability challenge,” said Boris Kriuk, who directed the multi-year research effort. “Permafrost degradation doesn’t just damage individual buildings—it threatens the viability of entire cities, transportation networks, and energy infrastructure that millions of people depend on. Our study provides the first comprehensive risk map enabling proactive adaptation rather than reactive crisis management.”
The Arctic warms at four times the global…
