Exploring DNA/RNA-Seq Analysis Results with Golden Helix GenomeBrowse and SVSGolden Helix Inc
GenomeBrowse, a free visualization tool for all types of sequence data, was introduced in 2012 to broad acclaim. Researchers using GenomeBrowse discovered a product far beyond the status quo with seamless navigation of sequence alignments and other genomic data using a fluid, fast, and intuitive interface that just "made sense." Recent updates to GenomeBrowse, including support for VCF files and BED files and the ability to export tables of data extracted from viewable annotation tracks, further improved the product and created new synergy with Golden Helix SNP & Variation Suite (SVS).
This webcast will demonstrate the ability of GenomeBrowse to stream sequence alignment data from the Amazon Cloud, seamlessly transitioning between whole genome views and base-pair resolution in the context of both public and custom annotation tracks. We will show how GenomeBrowse can be used in conjunction with SVS to highlight false variant calls, confirm the inheritance pattern of putative functional variants, and aid in the interpretation of a variant's impact. Examples of RNA-seq expression analysis, somatic variation in cancer, and family-based DNA-seq analysis will be included.
"A biological database is a large, organized body of persistent data, usually associated with computerized software designed to update, query, and retrieve components of the data stored within the system. A simple database might be a single file containing many records, each of which includes the same set of information."
Genomic Big Data Management, Integration and Mining - Emanuel WeitschekData Driven Innovation
Thanks to Next Generation Sequencing (NGS), a technology that is lowering the cost and time of reading DNA, we are faced with huge amounts of biomedical data. These data are continuously collected by research laboratories, and often organized through world-wide consortia, which are releasing many public data bases. One of the main aims of bioinformatics is to solve fundamental issues in biomedicine research (e.g., how cancer occurs) starting from big genomic data and their analysis. In this talk I will give an overview of big genomic data management, integration, and mining.

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.

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

• Structured collection of information.
• Consists of basic units called records or entries.
• Each record consists of fields, which hold pre-defined
data related to the record.
• For example, a protein database would have protein
entries as records and protein properties as fields (e.g.,
name of protein, length, amino-acid sequence)
THE ‘PERFECT’ DATABASE

Direct Submission
• A typical GenBank submission consists of
a single, contiguous stretch of DNA or
RNA sequence (contigs) with annotations
(metadata).
• If part of a nucleotide sequence encodes a
protein, a conceptual translation, called a
CDS (coding sequence) is annotated.
High-Throughput Genomic
Sequence (HTGS)
• HTGS entries are submitted in bulk by
genome centers, processed by an
automated system, and then released to
GenBank.
• Currently, more than 30 genome centers
are submitting data for a number of
organisms, including human, mouse, rat,
rice, and Plasmodium falciparum.
13. 10/11/2017
13
Whole Genome Shotgun
Sequences (WGS)
• Shotgun sequence reads are assembled into contigs,
submitted, and updated as the sequencing project
progresses and new assemblies are computed.
Submission Tools
• BankIt: Web-based form for submission of
a small number of sequences with minimal
annotation to GenBank.
• Sequin: More appropriate for complicated
submissions containing a significant
amount of annotation or many sequences.
14. 10/11/2017
14
Sequence Data Flow and
Processing
• Within 48 hours of direct submission with BankIt or Sequin,
the database staff reviews the submission to determine
whether it meets the minimal criteria and then assigns an
Accession number.
– All sequences must be > 50 bp in length and be sequenced by,
or on behalf of, the group submitting the sequence.
– GenBank will not accept sequences constructed in silico
– GenBank will not accept noncontiguous sequences containing
internal, unsequenced spacers.
– GenBank will not accept sequences for which there is no
physical counterpart, such as those derived from a mix of
genomic DNA and mRNA.
– Submissions are checked to determine whether they are new or
updates.
Sequence Data Flow and
Processing
• Indexing:
– Biological validity: Translation, organism lineage, BLAST
searches
– Vector contamination: Is there any vector DNA present in the
sequence?
– Publication status: If published, citation is included in annotation
and linked to Entrez
– Formatting and spelling
• Sequences are sent to submitter for final review before
release into the public database.
• Sequences must become publicly available once the
accession number or the sequence has been published.
• GenBank annotation staff process about 1900
submissions/month, or about 20,000 sequences.
