Global warming is the gradual increase in the earth’s temperature generally due to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.
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 .

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

(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.
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.
Richard's entangled aventures in wonderlandRichard 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.
1. Global Warming
• What is Global Warming?
• What are the Causes of Global Warming?
• What are the Effects of Global Warming?
• Mitigation / Solution of Global Warming
2. Global Warming
Global Warming is the heating up of our of our planet.
The increase in the world’s average temperature, believed to result from the
release of carbon dioxide and other gases into the atmosphere by the burning
of fossil fuels.
3. Natural Greenhouse Effect
The greenhouse effect is a natural process that warms the Earth’s surface.
When the Sun’s energy reaches the Earth’s atmosphere, some of it is
reflected back to space and the rest is absorbed and re-radiated by
greenhouse gases.
Greenhouse gases include water vapour, carbon dioxide, methane, nitrous
oxide, ozone and some artificial chemicals such as chlorofluorocarbons
(CFCs).
The absorbed energy warms the atmosphere and the surface of the Earth.
This process maintains the Earth’s temperature at around 33 degrees Celsius
warmer than it would otherwise be, allowing life on Earth to exist.
4. Enhanced Greenhouse Effect
The problem we now face is that human activities – particularly burning fossil fuels
(coal, oil and natural gas), agriculture and land clearing – are increasing the
concentrations of greenhouse gases. This is the enhanced greenhouse effect, which is
contributing to warming of the Earth.
Step 1: Solar radiation reaches the Earth's atmosphere - some of this is reflected
back into space.
Step 2: The rest of the sun's energy is absorbed by the land and the oceans,
heating the Earth.
Step 3: Heat radiates from Earth towards space.
Step 4: Some of this heat is trapped by greenhouse gases in the atmosphere,
keeping the Earth warm enough to sustain life.
Step 5: Human activities such as burning fossil fuels, agriculture and land clearing
are increasing the amount of greenhouse gases released into the atmosphere.
Step 6: This is trapping extra heat, and causing the Earth's temperature to rise.
6. What are the enhanced greenhouse
gases?
Earth's atmosphere is mostly made up of nitrogen and oxygen, but these are
not greenhouse gases. Greenhouse gases are the substances that trap heat,
and they are naturally less abundant in the atmosphere.
Water vapor is a greenhouse gas, as well as carbon dioxide, methane, nitrous
oxide, ozone, hydrofluorocarbons (HFCs), Perfluorocarbons (PFCs), sulfur
hexafluoride (SF6)
The amount of greenhouse gases in the atmosphere affects the strength of
the greenhouse effect.
Plants reduce the greenhouse effect by absorbing carbon dioxide from the air,
while human activities like manufacturing increase the greenhouse effect by
adding various greenhouse gases.
7. The Enhanced Greenhouse Gases
CARBON DIOXIDE
Carbon dioxide is produced by power stations, factories and road vehicles that burn
fossil fuels. Deforestation and the burning of rainforests also produces carbon dioxide.
METHANE
Methane is released from waste dumps, farms and rice fields.
NITROUS OXIDES NITROUS OXIDES
Nitrous oxides are emitted from car exhausts, power exhausts, power stations and
fertilizers.
CFC’S (CHLOROFLUOROCARBONS)
These are released from aerosols, plastic, foam packaging and fridges. They are the
most dangerous of greenhouse gases as they absorb more heat than carbon dioxide.
Hydrofluorocarbons (HFCs)
organic compounds that contain fluorine and hydrogen atoms, are the most common
type of organofluorine compounds. They are commonly used in air conditioning and as
refrigerants
8. The Enhanced Greenhouse Gases
PERFLUOROCARBONS (PFCS)
sometimes referred to as perfluorocarbons or PFCs organofluorine
compounds that contain only carbon and fluorine, wherein all C-H bonds have
been replaced by C-F
SULFUR HEXAFLUORIDE (SF6)
is an inorganic, colorless, odorless, non-flammable, extremely potent
greenhouse gas, and an excellent electrical insulator. SF as an octahedral
geometry, consisting of six fluorine atoms attached to a central sulfur atom. It
is a hyper valent molecule. Typical for a nonpolar gas, it is poorly soluble in
water but quite soluble in nonpolar organic solvents. It is generally
transported as a liquefied compressed gas. SF6 is used in several non-electric
and electronic applications.
NITROGEN TRIFLUORIDE* (NF3)
is the inorganic compound with the formula NF3. This nitrogen-fluorine
compound is a colorless, odorless, nonflammable gas. It finds increasing use
as an etchant in microelectronics. Nitrogen trifluoride is an extremely strong
greenhouse gas.
9. Global Warming:
Causes
Global warming is thought to be due to the enhanced greenhouse effect
enhanced greenhouse effect
The Earth is surrounded by a layer of gases, including carbon dioxide.
This keeps the Earth warm by preventing the escape of heat that would
normally be lost from the atmosphere.
The gases act rather like the glass in a greenhouse.
They let in heat but prevent most of it from getting out.
10. Global Warming:
Effects
Melting glaciers, early snowmelt, and severe droughts will cause more
dramatic water shortages and increase the risk of wildfires in the American
West.
Rising sea levels will lead to coastal flooding on the Eastern Seaboard,
especially in Florida, and in other areas such as the Gulf of Mexico.
Forests, farms, and cities will face troublesome new pests, heat waves, heavy
downpours, and increased flooding. All those factors will damage or destroy
agriculture and fisheries.
Disruption of habitats such as coral reefs and Alpine meadows could drive
many plant and animal species to extinction.
Allergies, asthma, and infectious disease outbreaks will become more
common due to increased growth of pollen-producing ragweed, higher levels
of air pollution, and the spread of conditions favorable to pathogens and
mosquitoes.
12. Mitigation / Solution
Reducing emissions of and stabilizing the levels of heat-trapping greenhouse
gases in the atmosphere
involves reducing the flow of heat-trapping greenhouse gases into the
atmosphere, either by reducing sources of these gases (for example, the
burning of fossil fuels for electricity, heat or transport) or enhancing
the “sinks” that accumulate and store these gases (such as the oceans,
forests and soil).
Adapting to the climate change already in the pipeline
involves adjusting to actual or expected future climate. The goal is to
reduce our vulnerability to the harmful effects of climate change (like
sea-level encroachment, more intense extreme weather events or food
insecurity).
13. Laws Enacted Concerning Global
Warming
The Kyoto Protocol
is an international treaty which extends the 1992 United Nations Framework
Convention on Climate Change (UNFCCC) that commits State Parties to reduce
greenhouse gas emissions, based on the scientific consensus that (a) global
warming is occurring and (b) it is extremely likely that human-made CO2
emissions have predominantly caused it. The Kyoto Protocol was adopted in
Kyoto, Japan, on December 11, 1997 and entered into force on February 16,
2005. There are currently 192 parties
The Paris Agreement
The Paris Agreement is the first truly global effort to reduce emissions. To
date, 160 UNFCCC parties have made voluntary pledges to reduce emissions
up to 2030, including China, the US and the European Union (on behalf of the
UK and other EU nations).
The main aim of the Paris Agreement is to hold the increase in global average
temperature to well below 2°C above pre-industrial levels and to pursue
efforts to limit warming to 1.5°C.
14. Laws Enacted Concerning Global
Warming
UNFCCC (United Nations Framework Convention on Climate Change)
created in 1992 as the main forum for international action on climate change. Its
overall aim is to:
195 countries have joined the international agreement (known as a
convention). Negotiations focus on four key areas:
mitigating (reducing) greenhouse gas emissions
adapting to climate change
reporting of national emissions
financing of climate action in developing countries
17. Ways to Reduce Greenhouse Gases
Reduce, Reuse, Recycle
Buying products with minimal packaging will help to reduce waste. By
recycling half of your household waste, you can save 2,400 pounds of carbon
dioxide annually.
Use Less Heat and Air Conditioning
Adding insulation to your walls and installing weather stripping or caulking
around doors and windows can lower your heating costs more than 25
percent, by reducing the amount of energy you need to heat and cool your
home. Turn down the heat while you’re sleeping at night or away during the
day, and keep temperatures moderate at all times. Install a programmable
thermostat because setting it just 2 degrees lower in winter and higher in
summer could save about 2,000 pounds of carbon dioxide each year.
18. Ten Ways to Reduce Greenhouse Gases
Replace Your Light Bulbs
Wherever practical, replace regular light bulbs with compact florescent light
(CFL) bulbs. Replacing just one 60-watt incandescent light bulb with a CFL
will save you $30 over the life of the bulb. CFLs also last 10 times longer than
incandescent bulbs, use two-thirds less energy, and give off 70 percent less
heat. If every Canadian family replaced one regular light bulb with a CFL, it
would eliminate 90 billion pounds of greenhouse gases, the same as taking 7.5
million cars off the road.
Drive Less and Drive Smart
Less driving means fewer emissions. Besides saving gasoline, walking and
biking are great forms of exercise. Explore the York Region Transit system and
check out options for carpooling to work or school.
19. Ten Ways to Reduce Greenhouse Gases
Buy Energy-Efficient Products
Home appliances now come in a range of energy-efficient models, and
compact florescent bulbs are designed to provide more natural-looking light
while using far less energy than standard light bulbs.
Use Less Hot Water
Set your water heater at 120 degrees to save energy, and wrap it in an
insulating blanket if it is more than 15 years old. Buy low-flow showerheads to
save hot water and about 350 pounds of carbon dioxide yearly. Wash your
clothes in warm or cold water to reduce your use of hot water and the energy
required to produce it. That change alone can save at least 500 pounds of
carbon dioxide annually in most households.
20. Ten Ways to Reduce Greenhouse Gases
Use the "Off" Switch
Save electricity and reduce global warming by turning off lights when you
leave a room, and using only as much light as you need. And remember to
turn off your television, stereo and computer when you're not using them. It’s
also a good idea to turn off the water when you’re not using it. While
brushing your teeth, shampooing the dog or washing your car, turn off the
water until you actually need it for rinsing.
Plant a Tree
If you have the means to plant a tree, start digging. Trees absorb carbon
dioxide and give off oxygen. A single tree will absorb approximately one ton
of carbon dioxide during its lifetime.
21. Ten Ways to Reduce Greenhouse Gases
Encourage Others to Conserve
Share information about recycling and energy conservation with your friends,
neighbours and co-workers, and take opportunities to encourage public
officials to establish programs and policies that are good for the environment.
