Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.

Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
1. FUN FACTS, CHARMS OF PHYSICS AND MORE
Fun with Electric Charge and
Coulombs Law
2. Introduction
William Gilbert, a personal doctor to Queen
Elizabeth I of England, who gave a scientific
description of electric charges.
Benjamin Franklin, an amateur scientist explained
the nature of electric charges.
Charles Du Fay did not accept the one-fluid theory of
Franklin. It was Du Fay who suggested the
possibility of two types of charges, one positive and
the other negative.
3. THAT’S THE CHARM OF PHYSICS #1
Electric Charge is not created, just
transferred from one object to
another, during rubbing of two
bodies.
4. JUST REMEMBER THIS #1
When bodies are rubbed against each
other they become charges due to the
transfer of electrons from one body to
the other. The charge stays where it is
and hence it is called static electricity.
5. THAT’S THE CHARM OF PHYSICS #2
Any net charge kept on a metal sphere spreads uniformly over
the surface of sphere very quickly. But the net charge placed
on an insulator will remain in that region.

7. REINVENT YOURSELF
Suppose q1q2 < 0. This means one charge is positive
and the other charge is negative. Then the electric
force between them will be attractive.
Suppose q1q2 > 0. This means the two charges are
similar, either (+) and (-). In either case the force
between them is repulsive.
If q1 + q2 = 0, then there will be force of attraction
between the two charges, even though the net
charge of the system is zero.
8. JUST REMEMBER THIS #2
Coulomb’s law can be applied to point charges.
Coulomb’s interaction is not affected by any other charge in
the surroundings.
Coulomb’s law is applicable to charges at rest. For charges
in motion, the equation must be modified.
Coulomb’s force holds good for very small distances up to
about 10-15
m. When the distance becomes less than that, the
coulomb’s force is dominated by the nuclear forces.
9. CONTD …
Coulomb’s force is a central force and hence it is an
example of conservative force. This means the work done
in moving a charge in an electrostatic field is independent
of the path followed.
The coulomb’s force exerted by one charge (q1) on another
charge (q2) is equal and opposite to the force exerted by q2
on q1. The magnitude of the force depends on the
magnitude of the charges, their separation and the nature
of the medium in between them. The direction of the force
depends upon the position of the charges.
10. CONTD …
The importance of Coulomb’s law is that.
a) It helps is to determine the forces acting between charged bodies.
b) It explores the biding force between electron and the nucleus in an
atom or molecule in solid or liquid.
Even though the protons and neutrons are held together
inside the nucleus through the strongest nuclear force
which does not depend upon the charge, it is due to electric
force that elements are radioactive and the elements are
beyond uranium are not stable.
