The agriculture sector is quickly emerging in platform economics, and the rapid development of digital interfaces does not entirely depend on supply and demand. Collaborative platforms, such as finance, renting farms, exchanging services, and produces such as seeds, fruits, vegetables, and others have also appeared along with marketplaces. As internet networks are expanding into rural areas and smart devices are penetrating the agriculture sector, more opportunities to use technology for the benefit of farmers are growing. The agricultural produce, supplies, equipment, among others, are available on various platforms.

Dicyclopentadiene is a chemical compound with the formula C10H12. It is co-produced in large quantities in the steam cracking of naphtha and gas oils to ethylene as part of the separation process of crude C5 streams. It is a colorless, waxy, flammable solid or liquid with a camphor-like odor. Dicyclopentadiene is highly flammable, with a flashpoint of 90°F/32°C and a boiling point of 338ºF/170°C. The major uses are in resins, particularly unsaturated polyester resins. As a chemical intermediate, it is used for making insecticides, hardeners, and dryers in linseed and soybean oil and in the production of ethylene propylene diene monomer (EPDM) elastomers, metallocenes, resins, varnishes, and paints.

CRISPR is a technology that is used in gene editing enabling researchers and scientists globally to alter DNA sequence and modify gene function with ease. CRISPR gene editing was adopted from the antivirus immunity system of single-celled microorganisms, namely archaea and bacteria. Fragments of alien DNA, known as a spacer, are incorporated and transcribed into guide crRNA (CRISPR RNAs) to specifically target and cleave the genome of the virus and other foreign bodies using Cas proteins. In other words, the CRISPR/Cas9 system directs the Cas9 nuclease to form a site-directed double-strand DNA break using a small RNA molecule that results in permanent alterations of the genomic target sequence and repair the damage caused to DNA. These components, when transferred into more complex organisms, enable gene editing or modifications.

Peptides are a selective, efficacious, and unique class of molecules that bind to specific cell surface receptors, triggering intracellular effects. They are short chains of amino acids linked by a peptide bond. Although they are molecularly poised between small molecules and proteins, peptides have distinctive therapeutic and biochemical properties. They represent an attractive first step in developing novel therapeutics across different areas, including oncology, metabolic, cardiovascular, infectious, endocrine, neurology, and other disorders. For decades, researchers have endeavored to comprehend intracellular protein-protein interactions (PPIs) as they play a critical role in the pathogenesis of numerous disease states. The development of constrained peptides exhibits an emerging approach that addresses challenging PPIs.

The study defines cancer microbiome as the aggregate of microorganisms living in or on the human body along with their genomes that are influencing cancer manifestation and progression. Cancer microbiome sequencing has increasingly become an area of interest for the research community, which has the potential to revolutionize cancer care, largely due to studies that have significantly correlated the microbiome’s involvement in cancer manifestation. This study aims at deciphering the potential of the cancer microbiome sequencing and its larger role in bolstering the current era of precision medicine.

In recent times, high emphasis has been laid on the adverse effects of conventional agriculture on the environment. Some of these concerns include depletion of natural resources, misuse of synthetic chemical inputs into the soil, and contamination of water resources. To meet the growing global food demand with the increasing population, which is expected to reach 9.74 billion by 2050, alternative, and optimized ways of growing and monitoring crops have been innovated, thereby implementing smart farming techniques. This has led to a great rise in alternative production systems within both small growers and large-scale commercial productions.
