Despite seemingly inexorable imminent risks of food insecurity that hang over the world, especially in developing countries like Pakistan where traditional agricultural methods are being followed, there still are opportunities created by technology that can help us steer clear of food crisis threats in upcoming years. At present, the agricultural sector worldwide is rapidly pacing towards technology-driven Precision Agriculture (PA) approaches for enhancing crop protection and boosting productivity. Literature highlights the limitations of traditional approaches such as chances of human error in recognizing and counting pests, and require trained labor.

Despite the development of adapted popcorn cultivars such as UENF WS01, strategies such as bacterial inoculation are being explored to enhance plant resilience to abiotic stress. This study investigates the impact of drought stress on popcorn cultivation. Specifically, the aim was to identify the benefits of interaction with the drought-tolerant hybrid UENF WS01 for its morphophysiology and growth by comparing inoculated and non-inoculated plants under water-stressed (WS) and well-watered (WW) conditions.

Article Synopsis
  • The rise of skin-like electronics has led to a demand for polymer semiconductors (PSCs) that are both stretchy and perform well electrically, but achieving this balance is challenging.
  • Researchers suggest using tris(pentafluorophenyl)borane (BCF) for Lewis acid doping to improve charge mobility while enhancing stretchability by increasing structural disorder.
  • Key findings show that adjusting the lamellar stacking distance and reducing crystallinity allows for better BCF incorporation, leading to a two-fold increase in carrier mobility and a 100% crack onset strain, with stable performance under significant strain over extended cycles.

Article Synopsis
  • - Onychomycosis is a common fungal nail infection causing discoloration and detachment of nails, with increasing cases attributed to non-dermatophyte molds (NDMs) in warmer climates, alongside traditional dermatophytes.
  • - Diagnosis is challenging due to high false-negative rates in standard methods, making histology and PCR more reliable, although they require careful handling to avoid contamination.
  • - Treatment includes oral antifungals with better cure rates but more side effects, and topical options that are safer but less effective; ongoing research focuses on improving delivery methods and emphasizes the need for preventive measures to reduce reinfection rates.

Background: Tuberculosis (TB) remains a significant cause of mortality globally, with India accounting for 27% of the estimated number of people with TB. Multidrug-resistant TB (MDR-TB) and isoniazid (INH) resistance pose additional challenges to effective treatment. We aimed to describe treatment outcomes of INH mono-resistant TB patients under programmatic conditions in Mumbai, India.

Aliphatic allylic amines are present in a large number of complex and pharmaceutically relevant molecules. The direct amination of allylic electrophiles serves as the most common method toward the preparation of these motifs. However, the use of feedstock reaction components (allyl alcohol and aliphatic amine) in these transformations remains a great challenge.

The surge in bacterial growth and the escalating resistance against a multitude of antibiotic drugs have burgeoned into an alarming global threat, necessitating urgent and innovative interventions. In response to this peril, scientists have embarked on the development of advanced biocompatible antibacterial materials, aiming to counteract not only bacterial infections but also the pervasive issue of food spoilage resulting from microbial proliferation. Protein-based biopolymers and their meticulously engineered composites are at the forefront of this endeavor.

Synthetic biology primarily focuses on two kinds of cell chassis: living cells and nonliving systems. Living cells are autoreplicating systems that have active metabolism. Nonliving systems, including artificial cells and nanoparticles, are nonreplicating systems typically lacking active metabolism.

A conformal reflective metasurface fed by a dual-band multiple-input multiple-output (MIMO) antenna is proposed for low-cost beam steering applications in 5G Millimeter-wave frequency bands. The beam steering is accomplished by selecting a specific port of MIMO antenna. Each MIMO port is associated with a beam that points in a different direction due to a conformal reflective metasurface.

Ultra-wideband (UWB) technology is extensively used in indoor navigation, medical applications, and Internet of Things devices due to its low power consumption and resilience against multipath fading and losses. This paper examines a multiple-input multiple-output (MIMO), circularly polarized (CP) dielectric resonator antenna for UWB systems. Compact form factor, high gain, wideband response, improved port isolation, and high data rates are the major design goals.

Avian migration is an intrinsic biological phenomenon that involves trans-boundary movements to evade adverse ecological circumstances. During migration, avian gut bacterial taxa may serve as a potential source of bacterial dissemination via fecal contamination at stop-over sites. Therefore, bacterial taxa composition as well as diversities were investigated employing 16S rRNA sequencing in fecal samples collected from flocks of seven migratory avian species visiting southern districts of Khyber Pakhtunkhwa, Pakistan.

Article Synopsis
  • Ureteral stents are critical devices for managing urinary tract issues like obstructions and stones, but a universally accepted material for these devices is still lacking.
  • This review highlights the potential of natural biopolymers, particularly alginate and chitosan, in the development and coating of ureteral stents, revealing that while alginate is effective in manufacturing, its usage as a coating is limited.
  • Chitosan is noted for its antibacterial properties and is more commonly used for coating stents, although both polymers face challenges in application, emphasizing the need for further research to optimize their use in stent technology.

The production of living therapeutics, cell-based delivery of drugs and gene-editing tools and the manufacturing of bio-commodities all share a common concept: they use either a synthetic or a living cell chassis to achieve their primary engineering or therapeutic goal. Live-cell chassis face limitations inherent to their auto-replicative nature and the complexity of the cellular context. This limitation highlights the need for a new chassis combining the engineering simplicity of synthetic materials and the functionalities of natural cells.

Background: Biannual ultrasound (US) is recommended for hepatocellular carcinoma (HCC) surveillance in patients with cirrhosis. However, US has limited sensitivity for early-stage HCC, particularly in overweight cohorts, where hepatic visualisation is often inadequate. Currently there are no robust imaging surveillance strategies in patients with inadequate US visualisation.
