Background
Biologists have long organized living things into large groups called kingdoms.
There are six of them:
Archaebacteria
Eubacteria
Protista
Fungi
Plantae
Animalia
Some recent findings…
In 1996, scientists decided to split Monera into two groups of bacteria:
Archaebacteria and Eubacteria
Because these two groups of bacteria were different in many ways scientists created a new level of classification called a DOMAIN.
Now we have 3 domains
Bacteria
Archaea
Eukarya
KingdomArchaebacteria
Any of a large group of primitive bacteria having unusual cell walls, membrane lipids, ribosomes, and RNA sequences, and having the ability to produce methane and to live in anaerobic, extremely hot, salty, or acidic conditions
The Domain Archaea
“ancient” bacteria
Some of the first archaebacteria were discovered in Yellowstone National Park’s hot springs
Prokaryotes are structurally simple, but biochemically complex
Basic Facts
They live in extreme environments (like hot springs or salty lakes) and normal environments (like soil and ocean water).
All are unicellular (each individual is only one cell).
No peptidoglycan in their cell wall.
Some have a flagella that aids in their locomotion.
Most don’t need oxygen to survive
They can produce ATP (energy) from sunlight
They can survive enormous temperature extremes
They can survive under rocks and in ocean floor vents deep below the ocean’s surface
They can tolerate huge pressure differences
STRUCTURE
Size
Archaea are slightly less than 1 micron long.
A micron is 1/1,000 of a millimeter.
In order to see their cellular features, scientists use powerful electron microscopes.
Shape
Shapes can be spherical or ball shaped and are called coccus.
Others are rod shaped, long and thin, and labeled bacillus.
Variations of cells have been discovered in square and triangular shapes.
STRUCTURE
Locomotion
Some archaea have flagella, hair-like structures that assist in movement.
There can be one or many attached to the cell's outer membrane. Protein networks can also be found on the cell membrane, which allow cells to attach themselves in groups.
Cell Features
Within the cell membrane, the archaea cell contains cytoplasm and DNA, which are in single-looped forms called plasmids.
Most archaeal cells also have a semi-rigid cell wall that helps it to maintain its shape and chemical balance.
This protects the cytoplasm, which is the semi-liquid gel that fills the cell and enables the various parts to function.
STRUCTURE
Phospholipids
The molecules that make up cell membranes are called phospholipids, which act as building blocks for the cell.
In archaea, these molecules are made of glycerol-ether lipids.
Ether Bonding
The ether bonding makes it possible for archaea to survive in environments that are extremely acidic or al

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

7. TAXONOMY
Taxonomy is the science of classification of
organisms.
(Greek. ‘Taxis’ – arrangement; ‘nomos’ – law
Bacterial taxonomy consists of three separate,
but interrelated areas:
• Classification,
• Nomenclature and
• Identification.
7
8. • Classification is the arrangement of organisms
into groups (taxa) on the basis of similarities or
relationships.
• Nomenclature is the assignment of names to the
taxonomic groups according to international rules
International Code of Nomenclature of Bacteria
• The rules are maintained by ICSP
• Identification is the practical use of a
classification scheme to determine the identity of
an isolate as a member of an established taxon or
as a member of a previously unidentified species.
8
9. Etymology
• Etymology means "origin and historical
development of a word,
• "Etymology" is derived from Greek etymon
means "the truth" and thus aims at the true.
• In principle the language of biological
nomenclatural names is Latin.
• In nomenclature, words of Greek origin as well
as those of any other origin are "latinized“
before their use
9
10. latinisation
• Is the proctice of rendering a non latin name (or
word) in a latin style
• Latinisation is common proctice for scientific
names
• The main purpose of latinisation may be to
produce a name which is internationally
consistent
• Ex . Escherichia :
• named after Theodor Escherich, who isolated the
type species of the genus.
10
11. TAXONOMIC RANKS
Formal rank - Example
Domain - Bacteria
Phylum - Proteobacteria
Class - Alphaproteobacteria
Order - Xanthomonadales
Family - Xanthomonadaceae
Genus - Xanthomonas
Species - axanopodis
Pathovar - punicae
Xanthomonas axanopodis sub sp punicae

13. Compilation of known bacteria
In lab, you will use the most recent edition
of Bergey's Manual of Determinative Bacteriology,
published in 1994 and reprinted in 2000, to help you
identify your isolates
13
14. • The volumes are organized according to
molecular classification systems including
16s rRNA sequences rather than by
phenotypic characteristics
• Basis for classification
the 'gold standard' for determining phylogenetic
relationships is DNA:DNA homology by
hybridization or genomic sequencing.

20. The organization of Bergey's Manual of Systematic
Bacteriology makes it impractical for helping place
unknown bacteria into major taxa,
BUT it contains far more detail on the families,
genera, and species and is far more up to date than
the Determinative manual.

About a hundred new genera and 600+ new species
have been described per year for each of the last 5
years.

27. As of January 2016, there are 30 phyla in the domain
"Bacteria" accepted by LPSN.
(List of Prokaryotic Names with Standing in Nomenclature )
• There are no fixed rules to the nomenclature
of bacterial phyla.
• Generally the name of the phylum is the
plural of the type genus, ( ex. Fusobacteria
from Fusobacterium)
• With the exception of the Firmicutes,
Tenericutes, Crenarchaeota,
and Proteobacteria, whose names do not
stem from a genus name
27
29. Volume 2 of the Manual covers the Proteobacteria (most
gram negative bacteria) in three parts.
This volume is subdivided into three parts.
• Part A - The Introductory Essays,
• Part B - The Gammaproteobacteria and
• Part C - The Alpha-, Beta-, Delta- and
Epsilonproteobacteria.
The majority of gram negatives will be found in part B.
Look in part C if a description of your species is not in
volume B.
29
30. PROTEOBACTERIA
• In 1988, Stackebrandt et al. named the
Proteobacteria after the Greek god Proteus,
who could assume many different shapes, to
reflect the enormous diversity of
morphologies and physiologies observed
within this bacterial phylum.
30
31. PROTEOBACTERIA
The largest prokaryotic phylum
Phenotypically most diverse phylogenetic lineage.
It encompasses 74 families and includes descriptions of
425 genera and over 1875 named species.
(Out of 425, I am going to mention 47 important genera)
account for more than 40% of all validly published
prokaryotic genera
