Induced mutagenesis has emerged as an essential field of plant breeding to address global food security challenges, offering tools to enhance crop productivity, resistance, and nutritional value. Among the mutation induction tools, the physical mutagen such as gamma rays holds promise for efficient mutation induction. Gamma rays, a type of high-energy electromagnetic radiation, possess unique characteristics that enable them to penetrate plant tissues and induce genetic mutations. The biological effects are influen [...]

The performance of metal-ion batteries at low temperatures and their fast charge/discharge rates are determined mainly by the electrolyte (ion) transport. Accurate transport properties must be evaluated for designing and/or optimization of lithium-ion and other metal-ion batteries. In this review, we report and discuss experimental and atomistic computational studies on ion transport, in particular, ion diffusion/dynamics, transference number, and ionic conductivity. Although a large number of studies focusing on l [...]

Meditation describes a large variety of traditions that are extremely variable, but all include the conscious focus or awareness of attention. By maintaining their attention, meditators experience both acute and long-term changes in physiology, anatomy, and cognitive performance. The literature shows that the type of performance benefits may depend on the specific type of mental training. During meditation practice there is a documented increase in neuronal coordination and slowing of neuronal firing across many re [...]

Uniparental disomy (UPD), the inheritance of both homologues of a chromosome from only one parent, has been reported for nearly all human chromosomes. Depending on its mode of formation and time of occurrence, UPD can be present in all cells of an organism, or restricted to some cell lines as a mosaic UPD. Though its general frequency is unknown, it becomes clinically relevant when it produces homozygosity for recessive pathogenic variations or is associated with chromosomal imbalances. UPDs are well-known for thei [...]

Recently, microplastics have emerged as a major environmental pollutant and have been documented globally. Several studies have shown that microplastics can accumulate heavy metals and persistent organic pollutants as they pass through the environment due to their functional groups interacting with and complex these substances. While conventional wastewater treatment methods can reduce a significant amount of microplastics, many still make their way into rivers and oceans worldwide from their effluents. One of the [...]

Numerous studies have explored the prevalence of depression and anxiety symptoms among university students worldwide. However, only a few have examined how these symptoms affect students' academic performance. This systematic review explores the relationship between depression, anxiety, and academic performance among undergraduate university students. Peer-reviewed articles published between 1997 and June 2020 were included if they: (a) were in English; (b) had a study population that was exclusively undergraduate [...]

Despite continuous efforts to combat neurodegenerative diseases, researchers have been unable to find an intervention that reverses degeneration and/or improves cognition in dementia or healthy aging. Therefore, it is considerably important to identify lifestyle factors that could potentially aid in healthy brain aging and prevent or delay neurodegenerative diseases. The emerging interest in the ancient practice of fasting has inclined researchers to study the physiological and behavioral effects of this practice. [...]

Emotional regulation (ER) is the process by which people change their physiology, expressions, and emotional experiences to operate in their daily lives. Deficits in emotion control may be connected to physical and mental health consequences. This review aims to identify genetic variants, understand neurobiological mechanisms, and explore behavioral phenotypes associated with ER. In our study, we included English studies from online databases such as Web of Science, Cochrane Library, Google Scholar, PubMed, and Sco [...]

Polymers such as polyimides and fluoropolymers are widely used for insulating aeronautic wires. They are exposed to various changing factors such as temperature, pressure, moisture, vibration, chafing, etc. The electrification on the horizon can potentially increase the demand for these systems. Indeed, this impending evolution of technology pushes the boundaries of commonly-employed wires. Downsizing systems and enhancing the performance is an urgent requirement. A new generation of insulating materials capable of [...]

(1) Background: Meditation is a common intervention for college students suffering from issues with anxiety. Due to this popularity, several meditation-based video games have been released which can be used to supplement or motivate meditation practice. However, these tools are not often given scrutiny in a laboratory setting before being released to the public. Our lab conducted a brief feasibility pilot study to investigate Meditation Deathmatch, an open-source meditation video game aimed at stimulating meditatio [...]
