What is the importance of organic Biopesticides in farmingShivaniPadole
Biopesticides are derivatives of plants, microorganisms and insects. Substances from plants and animals have been utilized to manage disorder in crops, animals and humans. Reliance on nature to mend nature is a practice for many people around the world. Use of natural products was overtaken by synthetic chemicals due to their effectiveness, reliability and fast knocks down effect. However, Organic pesticides have become a health risk for humans and environment due to their harmful and pollution.

Pest control is the regulation or management of a species defined as a pest, a member of the animal kingdom that impacts adversely on human activities. The human response depends on the importance of the damage done, and will range from tolerance, through deterrence and management, to attempts to completely eradicate the pest. Pest control measures may be performed as part of an integrated pest management strategy.

Bioremediation of Chlorpyrifos Contaminated Soil by MicroorganismIJEAB
India is agricultural based country where 70% of the population survives on it. In order to increase the production of field various pesticides are used. Chlorpyrifos (O,O-diethyl O-3,5,6-trichloro-2-pyridyl phosphorothioate) is an organophosphate pesticide which is widely used as insecticide for crop protection. But due to its persistent nature into the environment, it is leading to various hazards including neurotoxic effects, cardiovascular diseases and respiratory diseases. Bioremediation is a technology to eliminate chlorpyrifos efficiently from the environment. In bioremediation of chlorpyrifos the potential degradative microorganisms possess opd (organophosphate degrading) gene which hydrolyses the chlorpyrifos and utilizes it as a sole carbon source.Thus the present review discusses about how through bioremediation the pesticide chlorpyrifos can be degraded using potential soil microorganisms.
Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.
Professional air quality monitoring systems provide immediate, on-site data for analysis, compliance, and decision-making.

Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting
Binds with target MRNA in mismatch
Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .
Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.

2. General
• Immense commercialisation of agriculture has had a
very negative effect on the environment. The use of
pesticides has led to enormous levels of chemical
build-up in our environment, in soil, water, air, in
animals and even in our own bodies. Fertilisers have a
short-term effect on productivity but a longer-term
negative effect on the environment where they remain
for years after leaching and running off, contaminating
ground water and water bodies. The use of hybrid
seeds and the practice of monoculture has led to a
severe threat to local and indigenous varieties, whose
germplasm can be lost for ever. All this for
"productivity".
3. In the name of growing more to feed the earth, it
has taken the wrong road of unsustainability. The
effects show - farmers committing suicide in
growing numbers with every passing year; the
horrendous effects of pesticide sprays, pesticide
contaminated bottled water and aerated
beverages are only some instances. The bigger
picture that rarely makes news however is that
millions of people are still underfed, and where
they do get enough to eat, the food they eat has
the capability to eventually kill them.
4. Losses due to Pests
Insect pests, diseases and weeds are the major constraints
limiting agricultural productivity growth. It is estimated that
herbivorous insects eat about 26 percent of the potential
food production. Emerging problems of insecticide
resistance, secondary pest outbreak and resurgence further
add to the cost.
India are estimated to be 18 percent of the agricultural
output. Losses caused by specific pests may be higher.
Helicoverpa spp. in cotton causes losses up to 50 percent.
According to Raheja and Tewari (1996), H. Armigera
(American bollworm) alone causes an annual loss of about
Rs1000 crores.
5. • Another negative effect of this trend has been on the fortunes of
the farming communities worldwide. Despite this so-called
increased productivity, farmers in practically every country around
the world have seen a downturn in their fortunes. This is where
organic farming comes in. Organic farming has the capability to take
care of each of these problems. Besides the obvious immediate and
positive effects organic or natural farming has on the environment
and quality of food, it also greatly helps a farmer to become
selfsufficient in his requirements for agro-inputs and reduce his
costs. Modern farming affects our world, by the way of land
exhaustion, nitrate run off, soil erosion, soil compaction, loss of
cultivated biodiversity, habitat destruction, contaminated food and
destruction of traditional knowledge systems and traditions. Thus
to overcome the ill effects of modern agriculture, can be delineated
by adopting organic farming.
6. The production losses have shown an increasing trend over
the years. In 1983, the losses due to insect pests were
estimated worth ₨ 6,000 crores (Krishnamurthy Rao and
Murthy, 1983), which increased to ₨ 20,000 crores in 1993
(Jayaraj,1993) and to 29,000 crores in 1996 (Dhaliwal and
Arora, 1996). New pests have appeared due to the changes
in the cropping patternsand the intensive agricultural
practices.
7. Pest resistant varieties:
• Breeding for pest resistance is a continuous process. At the same
time the pests also, particularly the plant pathogens, co-evolve with
their hosts. Thus, gene transfer technology is useful in developing
cultivars resistant to insects, plant pathogens and herbicides. An
example of this is the incorporation of genetic material from
Bacillus thuringiensis (Bt), a naturally occurring bacterium, in
cotton, corn, and potatoes, which makes the plant tissues toxic to
the insect pests. Scientific community is impressed by its huge
potential in managing the pests, but is also concerned about the
possibility of increased selection pressure for resistance against it
and its effects on non-target natural fauna. However, due to ethical,
scientific and social considerations, this potential technology has
been surrounded by controversies.
8. Physical or mechanical controls
These are based on the knowledge of pest behaviour.
• Placing plastic-lined trenches in potato fields to trap
migrating Colorado potato beetles is one example of the
physical control.
• Shaking of the pigeonpea plant to remove Helicoverpa
larvae is a common practice in pigeonpea growing areas.
• Hand picking of insect pests is perhaps the simplest pest
control method.
• Installation of dead as well as live bird perches in cotton
and chickpea fields has proved effective in checking the
bollworm infestation.
• Using mulches to smother weeds and providing row covers
to protect plants from insects are other examples.
9. Cultural pest control
It includes crop production practices that make crop environment
less susceptible to pests. Crop rotation, fallowing, manipulation of
planting and harvesting dates, manipulation of plant and row
spacing, and destruction of old crop debris are a few examples of
cultural methods that are used to manage the pests. Planting of
cover crops, nectar producing plants and inter-planting of different
crops to provide habitat diversity to beneficial insects are important
management techniques. Cover crops, often legume or grass
species, prevent soil erosion and suppress weeds. A cover crop can
also be used as a green manure, which is incorporated in the soil to
provide nitrogen and organic matter to the subsequent crop. When
incorporated in the soil, some cover crops of the Brassica family
have the ability to suppress nematode pests and wilt diseases. Left
in the field as residues, rye and wheat provide more than 90
percent weed suppression. Cultural controls are selected based on
knowledge of pest biology and development.
10. Biological controls
These include augmentation and conservation of natural enemies of
pests such as insect predators, parasitoids, parasitic nematodes,
fungi and bacteria. In IPM programmes, native natural enemy
populations are conserved, and non-native agents may be released
with utmost caution. Trichogramma spp. are the most popular
parasitoids being applied on a number of host crops. A number of
microorganisms such as Trichoderma spp., Verticillium spp.,
Aspergillus spp., Bacillus spp. And Pseudomonas spp. that attack
and suppress the plant pathogens have been exploited as biological
control agents.
11. Estimated demand of different
biopesticides to cover major crops
Bio-agents/Pheromones Demand to cover 50% of area
Trichoderma preparation 5000 tonnes
Trichogramma 4000 lakh cc
Helicoverpa NPV 4200 lakhs LE
Spodoptera NPV 19000 lakh LE
Helicoverpa pheromone trap 350 lakhs
Spodoptera pheromone trap 350 lakhs
