Cloning involves producing genetically identical copies of biological entities. In the 1950s, embryologists Briggs and King developed nuclear transplantation, a technique where the nucleus is transferred from one cell to an egg cell with its original nucleus removed. This revealed that nuclei from older embryos and tadpoles, when transplanted, can affect the developmental potential of the recipient egg cell. Cloning describes processes used to copy genetic material and produce clones that are identical to the original biological entity.

Cloning
This document provides an overview of cloning including:
1) A brief history of cloning experiments dating back to the 1800s and important early experiments on frogs and mammals.
2) An explanation of the three main methods scientists use to clone cells: blastomere separation, blastocyst division, and somatic cell nuclear transfer.
3) A discussion of the potential benefits of cloning such as developing cures for diseases using stem cells and preserving endangered species.
Genetic engineering 34
Genetic engineering is the process of manipulating genes to introduce desirable traits. It involves combining DNA from different organisms, such as inserting a gene for insulin into bacteria. The gene is inserted into a plasmid or virus vector and introduced into a host cell. This allows the production of proteins like insulin to treat diseases. While genetic engineering holds promise to treat diseases, some argue it could disrupt nature in unintended ways. Regulatory issues also exist regarding its applications and effects.
MSA
Cloning involves making a genetic duplicate of an organism with the same DNA. It can be done through somatic cell nuclear transfer where the nucleus of an adult cell is transferred into an egg cell with its nucleus removed. The reconstructed egg is stimulated to divide through electric currents or chemicals and develops into an embryo. Species that have been cloned include carp, mice, sheep, monkeys, pigs, and horses. Cloning can be used for reproductive purposes or to generate human embryos for medical research.
Genetic engineering
Genetic engineering allows scientists to directly modify an organism's genes to enhance traits. Examples include crops with increased pest resistance or modified oil content. Cloning organisms is also possible by splitting an early embryo into cells or transferring a cell nucleus into an unfertilized egg. Mutations in human genes occur naturally and can be inherited, unlike artificial changes through genetic engineering. Recombinant DNA techniques have been used to create bacteria that produce human insulin, growth hormone, and vaccines. Dolly the sheep was the first mammal cloned from an adult cell, providing evidence that somatic cell nuclear transfer can recreate a whole organism. While genetic engineering has benefits like curing diseases, some argue it is unethical and should be banned due to

Transforming the Genetic Characteristics of Cells
Steven A. Field, MD teaches high school and college biology courses, including work on transforming the genetic characteristics of cells in the laboratory. Transformation involves introducing plasmid DNA into chemically competent cells on ice, subjecting the cells to heat shock, and allowing them to recover in a rich medium, which ensures that only transformed cells containing the new DNA will grow and divide when plated with an antibiotic. The transformed cells can then be used for further research purposes.

Gene transfection or Method of gene transfer
Genetic Transfection is a very useful and basic molecular biology technique of introducing nucleic acids into cells. In general terms, to transfect means to introduce genetic material (DNA, RNA, siRNA) into eukaryotic cells using chemical methods and without the use of viruses or electroporation machines.
Cloning
There are three main types of cloning: gene cloning, reproductive cloning, and therapeutic cloning. Gene cloning involves collecting DNA fragments from an organism and cloning them into vectors. Reproductive cloning produces a genetic duplicate of an existing organism, like Dolly the sheep. It is opposed by some due to safety and ethical concerns. Therapeutic cloning creates embryonic stem cells which researchers hope to use to grow healthy tissues to replace damaged or diseased ones. Cloning offers both potential medical benefits like organ transplants and stem cell therapies, as well as risks like uncertainty in the process, inheriting diseases, and potential for abuse. Any discussion on cloning must consider both its value and inherent risks.

Animal Cloning Procedure, Problems and Perspectives
Cloning in farm animals has problems and perspectives. Key issues include developmental anomalies in cloned animals, the large offspring syndrome observed in cattle and sheep clones, and safety apprehensions regarding meat and milk from cloned animals. However, cloning also has potential applications for transgenic animal production, creating disease models, bioreactors, and research into xenotransplantation. It allows the propagation of elite livestock and conservation of endangered species. Further optimization is needed to improve cloning efficiency and resolve health issues.
History of Genetics Genetics Scope and applications of genetics
Genetics is the study of heredity and variation in living organisms. The key concepts are that genes contain DNA sequences that encode specific proteins, and genes are passed from parents to offspring. There are two main areas of genetics - classical genetics which studies inheritance patterns and molecular genetics which examines the structure and function of genes. Some important applications of genetics include improving agriculture, treating genetic diseases, conservation efforts, and genetic engineering. The history of genetics began with Mendel's experiments in the 1860s, was rediscovered in 1900, and has since involved many important discoveries that helped elucidate DNA structure and genetic mechanisms.

It also discusses cloning endangered species, human cloning for therapeutic purposes, and the in vitro fertilization process.
Powerpoint
Archaebacteria differ from eubacteria in that they lack peptidoglycan and have distinct membrane lipids, and their DNA sequences are more similar to eukaryotes. Archaebacteria thrive in harsh environments like digestive tracts, salty lakes, and oxygen-depleted mud. Prokaryotes use flagella for movement and undergo cellular respiration for energy. They can also exchange genes between cells through conjugation. Prokaryotes reproduce through binary fission, doubling in size before dividing into two daughter cells.
Introduction to Genetic Engineering
The document discusses various applications of genetic modification and cloning technologies:
- Scientists are developing genetically modified cabbage that produces scorpion toxin to deter caterpillars without harming humans.
- Researchers have bred cows that produce 25% less methane gas by identifying the bacterium responsible for methane production.
- Goats have been genetically engineered to produce spider silk protein in their milk for manufacturing strong biosteel material.
- South Korean scientists genetically modified cats to glow in the dark by inserting a fluorescent gene.
Genetic engineering-stem-cells-and-cloning-
The document discusses genetic engineering, stem cells, and cloning. It defines genetic engineering as the manipulation of an organism's DNA to produce desired traits, but notes it is an imprecise technology. Stem cells are cells that can differentiate into other cell types and have potential medical applications, but their use is controversial. Cloning produces genetically identical organisms and there are three main types, but cloning techniques remain risky and result in many failed pregnancies or deformities in animals.
Cloning
Human cloning can be done through reproductive cloning or therapeutic cloning. Reproductive cloning implants a cloned embryo into a surrogate mother, while therapeutic cloning destroys cloned embryos to harvest stem cells. The cloning process involves removing the DNA from an egg and replacing it with DNA from the organism being cloned. While animals like mice, sheep and monkeys have been successfully cloned, human cloning poses high risks like miscarriage and health issues for the egg donor. The cost of human cloning is between $1.7-2 million. The document discusses pros and cons of using human clones for organ transplants.
Corona

Several human coronaviruses have been discovered since the 1960s. The seven known human coronaviruses are 229E, NL63, OC43, HKU1, SARS-CoV, MERS-CoV, and SARS-CoV-2 which causes COVID-19. Coronaviruses have a crown-like appearance and infect humans through contact with animals. They cause respiratory illnesses and have RNA genomes and spike proteins that allow entry into host cells.
REGULATING HEALTHY MEDIA USE
The document discusses ways to regulate media use to make it healthy for children. It recommends setting time limits on device usage, having kids track how much time they spend on media, and using technology to limit device usage. Additional tips include being a role model, not allowing devices at the dinner table, setting media-free time, insisting on homework before device time, and monitoring children's online activity. The goal is to encourage healthy media habits while still allowing play time and face-to-face communication.

The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
Equivariant neural networks and representation theory
Or: Beyond linear.
Abstract: Equivariant neural networks are neural networks that incorporate symmetries. The nonlinear activation functions in these networks result in interesting nonlinear equivariant maps between simple representations, and motivate the key player of this talk: piecewise linear representation theory.
