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.

Slide 1: Title Slide
Extrachromosomal Inheritance
Slide 2: Introduction to Extrachromosomal Inheritance
Definition: Extrachromosomal inheritance refers to the transmission of genetic material that is not found within the nucleus.
Key Components: Involves genes located in mitochondria, chloroplasts, and plasmids.
Slide 3: Mitochondrial Inheritance
Mitochondria: Organelles responsible for energy production.
Mitochondrial DNA (mtDNA): Circular DNA molecule found in mitochondria.
Inheritance Pattern: Maternally inherited, meaning it is passed from mothers to all their offspring.
Diseases: Examples include Leber’s hereditary optic neuropathy (LHON) and mitochondrial myopathy.
Slide 4: Chloroplast Inheritance
Chloroplasts: Organelles responsible for photosynthesis in plants.
Chloroplast DNA (cpDNA): Circular DNA molecule found in chloroplasts.
Inheritance Pattern: Often maternally inherited in most plants, but can vary in some species.
Examples: Variegation in plants, where leaf color patterns are determined by chloroplast DNA.
Slide 5: Plasmid Inheritance
Plasmids: Small, circular DNA molecules found in bacteria and some eukaryotes.
Features: Can carry antibiotic resistance genes and can be transferred between cells through processes like conjugation.
Significance: Important in biotechnology for gene cloning and genetic engineering.
Slide 6: Mechanisms of Extrachromosomal Inheritance
Non-Mendelian Patterns: Do not follow Mendel’s laws of inheritance.
Cytoplasmic Segregation: During cell division, organelles like mitochondria and chloroplasts are randomly distributed to daughter cells.
Heteroplasmy: Presence of more than one type of organellar genome within a cell, leading to variation in expression.
Slide 7: Examples of Extrachromosomal Inheritance
Four O’clock Plant (Mirabilis jalapa): Shows variegated leaves due to different cpDNA in leaf cells.
Petite Mutants in Yeast: Result from mutations in mitochondrial DNA affecting respiration.
Slide 8: Importance of Extrachromosomal Inheritance
Evolution: Provides insight into the evolution of eukaryotic cells.
Medicine: Understanding mitochondrial inheritance helps in diagnosing and treating mitochondrial diseases.
Agriculture: Chloroplast inheritance can be used in plant breeding and genetic modification.
Slide 9: Recent Research and Advances
Gene Editing: Techniques like CRISPR-Cas9 are being used to edit mitochondrial and chloroplast DNA.
Therapies: Development of mitochondrial replacement therapy (MRT) for preventing mitochondrial diseases.
Slide 10: Conclusion
Summary: Extrachromosomal inheritance involves the transmission of genetic material outside the nucleus and plays a crucial role in genetics, medicine, and biotechnology.
Future Directions: Continued research and technological advancements hold promise for new treatments and applications.
Slide 11: Questions and Discussion
Invite Audience: Open the floor for any questions or further discussion on the topic.
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.

Transitional forms chapter 4.1 amphibian ancestors of reptiles -introduction to hylonomus
1. Amphibian Ancestors of Reptiles
It surprises us to no end to know
that small lizard like amphibians
of Paleozoic carboniferous times
were ancestors of successor giant reptiles
and fossils of proto reptiles or para reptiles
makes us eager to know more and more
about this fascinating transformation .
2.
3. Transitionalforms
CarboniferousCradle
Of
Ancestors of Reptiles
It was a period in which the earth was lush green
with flourishing ferns and tall Gymnosperms unseen,
lakes ,ponds and puddles were live with noisy frogs
swimming or hopping in and out of water in funny ways
and salamander like creepy creatures were in abundance;
vast jungles were full of giant scorpions & dragon flies
when some of the braver amphibians tried to remain
more & more on dry land and even lay eggs there, almost
experimenting how to make them survive on ground and
came up with the idea of amniotic eggs with hard shells
to save them from dessication ,gradually adapting to
terrestriallife pattern in hot and humid climate at that time.
let us see, one by one, who were these innovation loving
bold creatures which became the transitional forms leading
to evolution of reptiles in due course of time ,
5. Transitionalforms
Lizzae theLizard
We are small longish long tailed fellows
a bit Salamander likea bit lizard like
insectgulpinggentleguys
but don’t underestimateus please
for we are grand ancestorsof a ‘ race’
known for its fearsomelooks and largesize.
We are slenderfellows with small legs ,long tails
and a bodyfull of scales on back as well as belly
livingin fresh water lakes in carboniferousdays
called as Lizziethe lizard but not a lizardat all
we are actually reptiliomorph leposopondyli
close to both amniotesand amphibianguys.

7. Transitionalforms
Proterogyrinus
( Earlier tadpole !)
We looklike our terrestrial friends
with fivefingersand lateral eyes
longishhead ,long tail and strongfeet
able to hunt whileon the move
more at homein water than on land
we are reptiliomorpha Anthracosaurus
Embolomeri- amphibian guys.
We had slenderbodies,stronglimbs,long tails
black& whitestripesrunningdown our spines
splayed out legs ,and five digits on each foot
small needlesharp teeth ,largejaws ,yelloweyes
We were top predatorsof our time
with thin skinwe mostlylivedin water
but were capableof dashing out of water
and wander on land to grab the prey even
as big as car sized millipedelike Arthropleura
and eagle sized dragon flies.– Meganeura.

9. Transitionalforms
Solenodonsaurus
( Singletoothlizard)
Small amphibiansresembling
both didectomorphs!and amniotes ,
were carnivorous / insectivorous
reptiliomorpha with triangularfaces;
felt moreat ease on land than in water.
They had a hearingsystem
Similar to moderntetrapods
And sharp slightlycurved teeth
A build likethat of Didectomorphs
They were sisterlyto Anthracosaurs

11. Transitionalforms
Hylonomus
( Forest dweller )
These tinycreatures of hardlyeight inches
were ,unbelievably, the very firstreptiles
which roamed in jungles eatinginsects
living/dying in hollow trees trunks
were ancestorsof both synapsids& sauropsids
in ‘Canada’during hot humid carboniferousdays ..
Looking morelike a modernlizard
eatingmillipedes & snailsby smallteeth
they were fullyadapted to lifeon land
and were closelyrelated to Diapsids .
