Digital biomarkers refer to objective and measurable physiological and behavioral information gathered via digital devices, including smartphones, wearable sensors, and connected medical instruments. In contrast to traditional biomarkers that typically depend on lab evaluations or in‑clinic assessments, digital biomarkers are produced continuously within everyday environments. They capture indicators such as heart rhythms, activity levels, sleep behaviors, vocal attributes, typing patterns, and movement dynamics, turning routine interactions with technology into meaningful health insights.From Episodic Care to Continuous MonitoringConventional health checkups usually occur sporadically through infrequent clinic appointments and brief diagnostic evaluations, while digital biomarkers move this approach toward ongoing monitoring. Around-the-clock…

Augmented reality glasses and spatial computing platforms are evolving from niche experimental devices into essential computing instruments, a transition propelled by breakthroughs in hardware miniaturization, artificial intelligence, networking, and robust software ecosystems, all converging to reshape how digital experiences merge with the physical world and transform the ways people work, study, and engage with information.Focusing on Compact Form and Enhanced Wearability in Fundamental DesignOne major trend centers on creating lighter, more comfortable AR glasses that look much closer to ordinary eyewear. Earlier headsets were heavy and consumed significant power, which slowed their adoption. Newer models emphasize improved weight balance, slimmer…

Zero-knowledge proofs, or ZKPs, originated in academic cryptography and gained mainstream visibility through blockchain and privacy-focused cryptocurrencies. Their core promise is simple yet powerful: one party can prove a statement is true without revealing the underlying data. As enterprises face mounting pressure to protect sensitive information, comply with strict regulations, and still collaborate across organizational boundaries, this capability is proving valuable far beyond digital assets.A practical view of zero-knowledge proofsAt an enterprise level, ZKPs enable verifiable trust with minimal disclosure. Instead of sharing raw data, organizations can share proofs that specific conditions are met. For example, a company can prove…

Satellite internet has moved from a niche solution for remote locations to a cornerstone of next-generation connectivity. Falling launch costs, advances in satellite design, and tighter integration with terrestrial networks are reshaping how data is delivered globally. The result is a faster, more resilient, and more inclusive connectivity ecosystem that complements fiber, 5G, and future 6G networks.Low Earth Orbit Constellations Redefine PerformanceThe most influential development is the rapid expansion of Low Earth Orbit (LEO) satellite constellations, which operate roughly 300 to 1,200 kilometers above the planet and, thanks to their proximity, deliver far lower latency than the traditional geostationary satellites…

Satellite internet has evolved from a service mainly used in remote areas into a central element of emerging global connectivity, driven by lower launch expenses, improved satellite engineering, and closer coordination with ground-based networks, ultimately delivering a quicker, sturdier, and more accessible communication landscape that enhances fiber, 5G, and forthcoming 6G systems.Low Earth Orbit Constellations Redefine PerformanceThe most transformative trend is the rise of Low Earth Orbit (LEO) satellite constellations. Orbiting at altitudes of roughly 300 to 1,200 kilometers, LEO satellites dramatically reduce latency compared to traditional geostationary satellites positioned 35,786 kilometers above Earth.Key impacts include:Lower latency: Round-trip delays often…

Zero-trust security is an architectural approach that assumes no user, device, or application should be trusted by default, even when operating inside a corporate network. Access decisions are continuously evaluated using identity, device posture, context, and behavior. This model contrasts with perimeter-based security, which implicitly trusts users once they are inside the network.Cloud Adoption and the Fading Boundaries of the Network PerimeterOne of the strongest trends driving zero-trust adoption is the rapid migration to cloud and hybrid environments. Organizations increasingly rely on multiple public clouds, software-as-a-service platforms, and APIs that extend beyond traditional firewalls.Workloads shift fluidly between different environments, rendering…

Industrial Internet of Things, widely known as Industrial IoT or IIoT, has progressed from simple connectivity and oversight into a strategic backbone for smarter operations, and this shift is seen most clearly in the departure from reactive and preventive maintenance toward predictive maintenance paired with rising degrees of operational autonomy, a change propelled not by hype but by tangible economic, technological, and operational pressures shaping contemporary industries.The Limitations of Traditional Maintenance ModelsFor decades, industrial assets were maintained using either reactive or preventive approaches. Reactive maintenance fixes equipment after failure, while preventive maintenance relies on scheduled servicing based on time or…

Robotic dexterity describes a machine’s capacity to handle objects with precise, adaptable, and dependable control even in dynamic, unpredictable settings. Activities like grasping uneven items, assembling parts, or managing delicate materials call for nuanced manipulation that has long been challenging to encode directly. By combining reinforcement learning with large-scale simulation, researchers are transforming how robots develop these abilities, shifting dexterity away from rigid automation and toward more flexible, human-like interaction.Core Principles of Reinforcement Learning for Skilled Dexterous ControlReinforcement learning is a learning paradigm in which an agent improves its behavior by interacting with an environment and receiving feedback in the…

Robotic dexterity refers to a machine’s ability to manipulate objects with precision, adaptability, and reliability in complex, changing environments. Tasks such as grasping irregular objects, assembling components, or handling fragile items require subtle control that has historically been difficult to program explicitly. Reinforcement learning and large-scale simulation have emerged as complementary tools that are reshaping how robots acquire these skills, moving dexterity from rigid automation toward flexible, human-like manipulation.Foundations of Reinforcement Learning for Dexterous ControlReinforcement learning is a learning paradigm in which an agent improves its behavior by interacting with an environment and receiving feedback in the form of rewards…

A recently detected asteroid will pass relatively close to Earth this Monday, attracting the interest of astronomers and space agencies worldwide. Even with the narrow cosmic distance, experts stress that the object poses no risk to the planet and will proceed safely along its trajectory through space.Astronomers are closely monitoring an asteroid identified as 2026JH2, a rocky object that will pass near Earth at a distance of approximately 91,593 kilometers, or about 56,900 miles. According to calculations from the European Space Agency, the object will travel at roughly one quarter of the average distance between Earth and the moon, making…
