Martha chase
Martha Chase was an American geneticist born in 1927 in Ohio who worked as a lab assistant to Alfred Hershey. She conducted a seminal experiment with Hershey in 1952 that demonstrated through a series of tests on viruses infecting bacteria that DNA, not protein, was the genetic material. This established her as making a crucial contribution to demonstrating that DNA carries genetic information. She received degrees from the College of Wooster and University of Southern California.
Alfred Hershey Presentation
Alfred Hershey was born in 1908 in Michigan. He received his PhD in bacteriology in 1934 from Michigan State University. In the 1950s, Hershey partnered with Martha Chase to conduct experiments tracking the transfer of proteins and DNA between viruses and bacteria. Using radioactive labeling, they found that DNA, not proteins, was transferred from the virus to the host bacterium, providing strong evidence that DNA is the genetic material. For this seminal work, Hershey and Chase were awarded the 1962 Nobel Prize in Physiology or Medicine. Hershey made many other contributions before his death in 1997 and is remembered as a pioneer in understanding the chemical basis of heredity.
What are encyclopedias ii
An encyclopedia is an organized collection of information on various topics that can be found in a library. It contains facts about people, places, animals, countries, history and other subjects. Students are instructed to select an animal from a basket, look it up in the encyclopedia located in the library, and write a sentence about that animal.
Protista
The Kingdom Protista includes single-celled eukaryotic organisms known as protists. Protists obtain energy through photosynthesis or consumption of organic matter, and can be found in various habitats around the world. They reproduce through mitosis or meiosis and cell division. Protists are classified based on characteristics like cell structure, energy source, and habitat. Examples of protists include algae, protozoa, water molds, and slime molds.
Annotated Bibliographies
Annotated bibliographies provide brief descriptive and evaluative paragraphs for citations to sources that inform readers of the relevance, accuracy, and quality of sources cited. To prepare an annotated bibliography, one must cite sources using MLA style, write concise annotations that summarize the central theme and scope of the source and its relevance to the project, and double space bibliographic citations and annotations. Examples of annotated bibliographies are provided for a book, newspaper article, and online reference article to demonstrate the proper MLA citation style and formatting of an annotation.
Citation exercise
This document provides a writing exercise that tests students' abilities to correctly format in-text citations in MLA style. The exercise presents 8 multiple choice questions, each with a short document citation and two response options for an in-text citation - one formatted correctly and one formatted incorrectly according to MLA style.

Background beliefs and the biology of homosexuality
This document summarizes a journal article about the biological basis of homosexuality. The article discusses how recent media coverage has highlighted scientific research finding biological causes of homosexuality. However, theories about biological influences on sexuality have existed since the 19th century. While advocates believe biological evidence will reduce discrimination, the research is limited and does not necessarily imply homosexuality is immutable or unchosen. It also does not include research on female homosexuality or bisexuality.
Background beliefs and the biology of homo
This document summarizes a journal article about the rhetoric surrounding research on the biological basis of homosexuality. The article discusses how past research on biological causes of sexuality dates back to the 19th century. Recent media coverage has hyped findings suggesting biological influences on homosexuality. However, using such biological arguments to advocate for gay rights is problematic. The research often does not include lesbians and argues bisexuality is not biological. Therefore, the biological basis for extending rights may be incomplete or inaccurate.

3 major experiments in confirming dna is the genetic material
The three key experiments that confirmed DNA is the genetic material are:
1) Frederick Griffiths discovered a "transforming principle" that could transfer traits from dead bacteria to live bacteria.
2) Avery determined that DNA was the molecule responsible for this transformation after isolating and testing DNA, protein and carbohydrates.
3) Hershey and Chase used radioactively labeled sulfur and phosphorus to track the transfer of genetic material from viruses to bacteria, proving that DNA rather than protein enters the bacterial cells.
Bio rhetoric, background beliefs and the bio of homo
This journal article summarizes and critiques arguments for biological bases of homosexuality. It notes that while recent media attention has focused on certain studies finding biological influences on homosexuality, scientific study of biological factors has occurred for over a century. However, the assumption that findings of biological influences will reduce discrimination is problematic. Specifically, the research often does not include lesbians or bisexuals and so may only benefit gay men legally. Additionally, basing the argument for gay rights entirely on scientific research leaves the argument vulnerable if that research is contradicted or made obsolete.
Bio rhetoric, background beliefs and the biology of homo
This journal article discusses a biological study from the 1990s that claimed to find a "gay gene" linked to male homosexuality. The article notes that while this research was hailed as supporting gay rights, it actually only benefited a specific group - male homosexuals. Additionally, relying too heavily on biological determinism to argue for gay rights places the movement in a precarious position, as later studies may contradict initial findings. The article argues the biological research on sexuality is more complex than advocates suggest and does not necessarily advance LGBT equality.

Wildlife tumors judy hoy
Researcher Judy Hoy has been documenting diseases and birth defects in wildlife for 50 years. She has observed increasing rates of cancers, tumors, and physical deformities in birds and mammals since 1995. Specifically, she has seen more cases of underdeveloped jaws, enlarged hearts, lung spots and bleeding, hoof problems, and malformed organs. Hoy believes these increases in health issues are linked to rising use of the herbicide Roundup on Roundup Ready crops in the region near her research area. The document includes photos of tumors observed on various birds and mammals between 2007-2010, which coincided with increased Roundup usage on local farms.

What Do You KNow About Dr. Seuss?
Theodor Geisel, better known as Dr. Seuss, wrote over 44 children's books in his career. Some of his most famous works included The Cat in the Hat, Green Eggs and Ham, and The Lorax, which all contained relatively small vocabularies but conveyed important messages. Before writing for children, Dr. Seuss drew political cartoons and advertisements. He found inspiration for his unique animal characters from visiting his father's zoo during his childhood. The last book published in his lifetime was Oh, the Places You'll Go in 1990, shortly before his death at age 87.

Framing Vem pra Rua
This document analyzes how Brazilian media outlets framed the 2013 protests in Brazil on news websites, blogs, and Twitter. It finds that initially, news websites used more "confrontation" frames but later shifted to more "legitimizing" frames as protest participation grew and demands became more generic and resonant. Blogs emphasized "debate" frames from the start. Twitter news accounts followed public support on Twitter, mirroring trends seen in previous Brazilian protests. The rise of a "rights" frame correlated with increased legitimizing coverage, supporting the hypotheses. Further analysis of frame sponsorship and impact on social movements is recommended.

This document analyzes journalists' use of humor on Twitter during the first 2012 US presidential debate:
- 17.9% of tweets from 430 political journalists analyzing the debate contained attempts at humor. Newspaper reporters had a slightly higher percentage.
- The use of humor was only positively correlated with retweets, not other Twitter activities like mentions or hyperlinks.
- While journalists traditionally restrain humor for objectivity, Twitter allows more transparency and engagement with audiences. Humor on the platform marks a break from strict reporting practices and could challenge elite news discourse.

In the 1950s, he partnered with Martha Chase to conduct experiments demonstrating that DNA, not proteins, was the genetic material. Their key experiment in 1953 used radioactive labeling to track DNA and proteins in viruses infecting bacteria. After blending the infected bacteria, they found that only DNA had transferred to the bacterial cells, proving that DNA carried genetic information. Hershey was awarded the Nobel Prize in 1962 and is renowned for his contributions to understanding the chemical basis of heredity through his work with Chase.

Joanie hermaphrodites-presentation-final2
This article explores the cultural perceptions and treatment of intersex people in America from 1620-1960. It discusses how early Americans viewed intersex births as monstrous punishments from God. Through the 1700s-1800s, medicine pathologized intersex people and surgeons began operating on infants to assign a rigid sex. By the 1900s, doctors aimed to "correct" ambiguous genitalia through surgery. Modern activists now challenge the two-sex system and medicalization of intersex variations.

This article explores the cultural and social perceptions of intersex people in America from 1620-1960. It discusses how early beliefs that intersex births were punishments from God led to intersex people being seen as subhuman. While medicine increasingly viewed intersex as a medical condition over time, stigma remained. The article analyzes changing definitions and several influential historical publications and cases. It concludes that misconceptions have supported a rigid two-sex system despite human biological diversity.

Introduction of Cybersecurity with OSS at Code Europe 2024
I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems.
The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS.
Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
