The design of nanomaterials for application in diverse fields ranging from photovoltaic to fluorescence sensing is a research area of increasing interest. Recently, Quantum Dots (QDs), which are classified as semiconductor quantum dots (SQDs) and Carbon dots (CDs), have become a hot topic of investigation, owing to their extraordinary tunable fluorescence emission properties that render them excellent candidates for sensing metal ions. The detection of metal ions in aqueous solutions with high sensitivity is very i [...]

Soil pollution is a major challenge for ensuring a healthy environment and for human health. One of the critical points in soil pollution policy is the education and public awareness of the problem caused by soil pollution. Education influences decision-making on soil and water care. It is crucial to spread knowledge to undergraduate and graduate students about the determinantal effects of soil pollution on ecosystems and humans, considering today’s students are tomorrow’s guardians of soil and human health. A cour [...]

Our new approach to MWD mud pulse telemetry offers significant increases over conventional data rates. Using waveguide acoustics, we show that common drilling communications channels support carrier frequencies exceeding several hundred Hertz. Such signals are prone to attenuation over large drill pipe distances. Low power, self-spinning “turbosirens” are designed, providing high torque and rotation rate performance at all flow rates without electric or hydraulic motor drives. The sirens rotate, drawing only on the [...]

Since the initial discovery of the CRISPR system in bacteria as an adaptive immune system, a deeper understanding of CRISPR structure and function has made it possible to perform gene editing, gene therapy, and revolutionize the diagnostic field. One of the exciting applications of the CRISPR-Cas system is used as a tool for the rapid diagnosis of infectious diseases and their treatment and the prevention of infection spread among people. The CRISPR-based diagnostic system could be the next-generation standard beca [...]

Cerebral palsy is defined as “A group of permanent disorders of the development of movement and posture, causing activity limitation, that are attributed to non-progressive disturbances that occurred in the developing fetal or infant brain. The motor disorders of cerebral palsy are often accompanied by disturbances of sensation, perception, cognition, communication, and behavior, by epilepsy, and by secondary musculoskeletal problems [1].” Between 30-40% of people with cerebral palsy also have epilepsy [2,3,4]. Som [...]

Multicellularity has gained the advantage over the unicellular world by expanding the number of increasingly more complex tissues that achieve advanced and specific functions. This same event gave rise to the most evolved group of organisms, namely mammals. Even though the complexity of multicellular organisms does not necessarily provide them with excellent adaptation modes performed by unicellular and prokaryotic organisms, this complexity per se stands as one of the greatest phenomena in biology. However, there [...]

The rights of nature have been widely discussed at a philosophical level for a long time, but examples of its practical application are quite rare. Ecuador is the first country to incorporate this concept into its constitutional foundation and put the theory into practice. However, implementing entirely justifiable rights of nature is hindered by factors, such as economic considerations, legal interpretations, cultural norms, political will, and disproportionate perspectives of “the greater good”. After getting opp [...]

The widespread usage of various wireless equipment in many facets of life has significantly contributed to the severe pollution caused by electromagnetic radiation. Thankfully, scientists have created materials that can absorb microwave radiation and convert dangerous electromagnetic waves into other forms of energy, including heat energy. Many recent investigations have been published regarding developing materials that absorb microwaves with different constituents, morphologies, and architectures. Microwave-absor [...]

Clinical islet transplantation was first realized over four decades ago at the University of Minnesota. Autologous islet transplantation is now widely recognized as a treatment to prevent diabetes in patients after pancreas excision and is offered at major transplant centers throughout the United States and the world. Type 1 diabetes represents a much larger demographic in which islet transplantation may benefit patients. Allogeneic islet transplantation can now offer similar outcomes to pancreas transplantation in [...]

There is a growing awareness that the proteins—amyloid-beta (Aβ) and tau—do not cause Alzheimer’s disease (AD) but are produced as a result of it. Similarly, doubt reigns over the degree of causality of high plasma cholesterol and prenylation in AD. This review proposes a fresh and important perspective, in addition to the current line of thinking. It emerges from comparative analysis, in evolutionary retrospect, of the characteristics of the mevalonate biosynthetic pathways in insects versus [...]
