  Seed treatment with carboxymethyl cellulose (CMC) is typically referred to as "priming" rather than "coating." Priming involves pre-treating seeds with various compounds, including chemicals, nutrients, hormones, or microorganisms, to enhance germination, early seedling growth, and overall plant performance. Seed priming has gained attention as a valuable technique in agriculture and horticulture, as it can lead to improved seedling establishment, reduced emergence variability, and better plant growth under various environmental conditions. It's worth noting that the effects of priming can vary based on the specific treatment, the plant species, and the growing conditions. In the context of using beneficial microorganisms and CMC for seeds, the term "priming" would be appropriate. The process involves allowing the seeds to absorb the beneficial compounds from the microorganism's culture and CMC solution, which can enhance their germination, nutri...

  Antifungal efficacy of Microrobots: Small robotics, specifically mobile robots with characteristic dimensions less than 1 mm, are known as microbotics or microrobots. A microrobot is a tiny robot designed to carry out particular tasks. A microrobot is typically somewhat bigger than a nanorobot, which is made at the nanoscale. While some nanobots are not instantly apparent to the human eye, microrobots are typically visible ( Margaret Rouse ).  Current treatments (such as nanoparticles) can have a variety of negative effects and function slowly and ineffectively. In addition, the problem of growing drug resistance diseases in the field of antifungal therapy.  Researchers at the University of Pennsylvania, Hyun (Michel) Koo and Edward Steager, joined forces with their teams in an initiative to use microrobots to target microbial coatings on soft surfaces. In an email to ASN, Koo stated, "Our study has developed a new strategy using tiny robotic particles called nanozyme m...

 NASA Posts Amazing Picture Of Space-Grown Flower NASA shared a picture of the zinnia plant, cultivated on the International Space Station  in 2015 . The goal was to find out how plants would grow in space.  According to a NASA report; Scientists have been studying plants in space since the 1970s, but this particular experiment was started on the  @ISS  in 2015 by NASA astronaut Kjell Lindgren. Kjell Lindgren, a NASA astronaut, initiated the experiment to observe how vegetation would grow in space since it would benefit humanity. During their lengthy space missions, the astronauts can eat a lot of food from this. Area for plant cultivation decreasing as the population increases day by day so there is a need to discover new spaces where the life of humans and plants could be possible.  Reference:  https://www.instagram.com/p/CtZxuGjSorR/?utm_source=ig_embed&ig_rid=b52ed06e-d24b-4db1-a0cf-2c004df423e1   

Design a Curriculum: The term curriculum comes from the Latin currier, which means "to run" or "proceed" and refers to the experiences that shape children as they grow to mature adults.  The term curriculum refers to  the academic content or syllabus and lessons taught in a school or educational institution or in a specific course or program . Step 1  Begin the design process by establishing our curriculum principles. The first step of curriculum principles should reflect our school’s values, context, pedagogical approaches, and needs. We should be able to explain the purpose or intent of our curriculum.  Step 2  After clarifying our principles and purpose, we should set out your pupil entitlement. The pupil entitlement should explain how we intend to enrich the curriculum with educational visits, extracurricular activities and specific experiences.  Step 3  We will need to arrange our curriculum content into a range of engaging themes and p...

 Curriculum organization:  Curriculum organization can be defined as it is a process of selecting curriculum elements from the subject, the current social life, and the student experience, then designing the selected curriculum elements appropriately so they can form the curriculum structure and type.  According to Ralph Tyler, essential changes in human behavior are not produced overnight. No learning experience has a very profound influence on the learner. Changes in the way of thinking in fundamental habits, major operating concepts, educational experience in attitudes, in abiding interests and the like develop slowly. It is only after months and years that, we are able to see major educational objectives taking marked concrete shape.  ➢ In short he wanted to say that Changes in human behavior gradually take place. The organization plays an important role in changes. Curriculum content: Curriculum content means the total of what is to be taught in...

Use of Magnetic field technique for seed germination  Seed germination Seed “independent structure” responsible for next generation of plants,  maintaining the germplasm, improving species diversity and production capacity.  Germination involves those processes which initiate with the uptake of water by the inactive dry seed and conclude with the development of the embryonic axis. The most important factors for germination include water, temperature, oxygen, and light.  Need of seed germination technique: Secure food to adopt new technologies 1) Improve grain yield and  2) germination rate by maintaining the crop quality. 3) To reduced amount of pesticides. 4) Low genetic deviation in seeds. Magnetic field (MF): Magnetic Field is the region around a magnetic material or a moving electric charge within which the force of magnetism acts.  The area around a magnet, where the force that is capable of magnetizing surrounding body exist is called a magnetic field...

DNA-Protein interactions: DNA-Protein interactions play an important role in any living cell. It controls cellular processes such as replication, transcription, recombination, DNA repair. There are many types of proteins found in a cell. Only those proteins interact with DNA, which have the DNA binding domains. These DNA binding domains possess an affinity to bind to double stranded or single stranded DNA. There are mainly two types of DNA-Protein interactions:  1) Sequence specific DNA binding:  In case of sequence specific DNA protein interactions, a DNA binding protein binds to a DNA on a site having a specific nucleotide sequence.  2) Sequence non-specific DNA binding In case of sequence non-specific DNA protein interactions, the DNA binding protein can bind to a DNA in a random position on the DNA. Techniques used for DNA-Protein Interaction: 1) Electrophoretic Mobility Shift Assay: This technique is based on the observation that Protein–DNA complexes are heavier and...
