The IoT world is a big world that everybody is talking about. IoT products nowadays come in different forms — some are labelled as IoT, but in fact they represent only a small portion of what an IoT product really entails. A fully fledged IoT project not only requires programming and hardware expertise but also expertise on a broad range of domains from energy to smart home and even automotive.
The purpose of this article is to highlight the significant differences among the Internet of Things (IoT) and Industrial Internet of Things (IIoT), and while walking through the listed considerations, the reader will have the chance to learn about their ecosystems and the particularities of their applications. Moreover, the gaps in the standardization of the technologies related to the IoT are presented along with the current initiatives from various institutions for mitigating these gaps.
Before talking about the differences between the IoT and IIoT, let’s look first at the similarities of the two. Both have the same fundamental layer on top of which they are built. With IIoT being a subset of the larger IoT, they automatically share common technologies like sensors, cloud platforms, connectivity and analytics.
Working at nanoscale dimensions, billionths of a meter in size, a team of scientists led by the Department of Energy’s Oak Ridge National Laboratory revealed a new way to measure high-speed fluctuations in magnetic materials. Knowledge obtained by these new measurements, published in Nano Letters, could be used to advance technologies ranging from traditional computing to the emerging field of quantum computing.
Many materials undergo phase transitions characterized by temperature-dependent stepwise changes of important fundamental properties. Understanding materials’ behavior near a critical transition temperature is key to developing new technologies that take advantage of unique physical properties. In this study, the team used a nanoscale quantum sensor to measure spin fluctuations near a phase transition in a magnetic thin film. Thin films with magnetic properties at room temperature are essential for data storage, sensors and electronic devices because their magnetic properties can be precisely controlled and manipulated.
The team used a specialized instrument called a scanning nitrogen-vacancy center microscope at the Center for Nanophase Materials Sciences, a DOE Office of Science user facility at ORNL. A nitrogen-vacancy center is an atomic-scale defect in diamond where a nitrogen atom takes the place of a carbon atom, and a neighboring carbon atom is missing, creating a special configuration of quantum spin states. In a nitrogen-vacancy center microscope, the defect reacts to static and fluctuating magnetic fields, allowing scientists to detect signals on a single spin level to examine nanoscale structures.
Ringworlds are one of science fiction’s most imaginative megastructures, essentially it is a giant ring that serves as a biosphere for an entire civilization or ecosystem at the very least, with the inside surface serving as a habitable world. Or Imagine a ring so enormous that its inner surface area could be equal to literally millions of Earths! The surface is designed to mimic a planetary environment, complete with cities, forests, and oceans. The structure would either orbit around a star or if it is big enough it would encircle the star. Using centrifugal force, its rotation is thus used to generate artificial gravity, while massive panels or “shadow squares” can be used to regulate light to create a day-night cycles. Obviously, contructing such a megastructure would require materials of super strength, far beyond anything currently known to exist and gathering resources for its construction could involve dismantling entire planets or asteroid belts. Can such things exist in reality? Maybe a higher tier alien civilization could make these, I don’t know, but in science fiction, there are quite a few of them out here & so lets take a look at the Biggest 10 of these ringworlds.

For the first time ever, a very low frequency radio telescope has successfully sent back astronomical data from the lunar surface. Although the mission didn’t quite go as planned, the data has enabled ground-based researchers to confirm the low frequency signature of our own Milky Way Galaxy. A team led by the University of Colorado at Boulder has published their results in The Astrophysical Journal.
We have demonstrated that radio astronomy from the Moon can be done at reasonable costs, and the science potential is high, Jack Burns, a co-author on the paper and a professor emeritus of Astrophysics at the University of Colorado Boulder, tells me via email.
The team used the NASA-funded $2.5 million ROLSES-1 (Radiowave Observations on the Lunar Surface of the photo-Electron Sheath) instrument sent to the Moon as part of Intuitive Machine’s 2024 Odysseus lander. Although Odysseus landed near the ‘Malapert A’ crater, within some 10 degrees of the Moon’s South Pole, it landed badly.
A deadly fungal epidemic in Brazil is evolving fast: pollution, cats, and genetics may be fueling its unstoppable spread.
Brazil is facing the world’s largest and most persistent sporotrichosis epidemic, a fungal infection spread primarily through cats. A new study reveals an alarming genetic diversity in the fungus, suggesting that urban pollutants may be accelerating its evolution. Researchers identified molecular markers that could enhance diagnostics and treatments, while also highlighting the rapid adaptation and virulence of Sporothrix brasiliensis.
