The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

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.
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

2018 was another record-breaking year when the total amount of seaweed reached approximately 6000 km2 (Source: Pfaff, M. (2015) Key scientific questions addressing environmental drivers and effects of periodic mass deposits of a brown seaweed (golden tides) along the Sierra Leone coast. Draft report for Oceans and Coastal Research, Directorate: Biodiversity and Coastal Research) with a weight of approximately 20 million tons in the month of June (Source: Wang, M., Hu, C., Barnes, B. B., Mitchum, G., Lapointe, B., & Montoya, J. P. (2019). The great Atlantic Sargassum belt. Science, 365(6448), 83-87.). The mass landings – in mounds up to two meters thick in some places – caused dreadful beaching events throughout the Wider Caribbean Region (WCR).
The Convention for the Protection and Development of the Marine Environment in the Wider Caribbean Region (WCR) or Cartagena Convention is a regional legal agreement for the protection of the Caribbean Sea.
The Convention was adopted in Cartagena, Colombia on 24 March 1983 and entered into force on 11 October 1986.
The Convention is supported by three technical agreements or Protocols on Oil Spills, Specially Protected Areas and Wildlife (SPAW) and Land Based Sources of Marine Pollution (LBS).
The Protocol Concerning Co-operation in Combating Oil Spills in the Wider Caribbean Region was adopted in 1983 and entered into force on 11 October 1986.
The Protocol Concerning Specially Protected Areas and Wildlife (SPAW) in the Wider Caribbean Region was adopted on 18 January 1990 and entered into force on 18 June 2000.
The Protocol Concerning Pollution from Land-Based Sources and Activities was adopted on 6 October 1999 and entered into force on 13 August 2010.
The Regional Coordinating Unit (UNEP-CAR/RCU) was established in 1986 in Kingston, Jamaica and is the Secretariat to the Cartagena Convention and its Protocols.
There is a lack of coordination both at the regional as well as global level as the issue is a transboundary one that also affect West Africa. (this is a basis/rationale for a possible UNEA resolution to foster global cooperation
Africa Atmosphere Dust, the world’s largest dust source (Prospero et al., 2014), has been also proposed to be a potential cause for the recent Sargassum blooms in the tropical North Atlantic (Johnson et al., 2013; Franks et al., 2014; Oxenford et al., 2015). The African dust transport has been found to cause a significant degradation of soils while the re-sedimentation provides a supply of nutrients (iron, phosphate) to terrestrial ecosystems and an increase in fertility in the area of dust settlement, as observed for the Amazon forest (Swap et al., 1992; Scheuvens et al., 2013).

We need to understand the correlations between the drivers and the occurrence of bloom events
This slide talks about understanding the drivers for the sargassum blooming via research.
Need to:
Take research coordination from the regional level to the global level, linking the Caribbean Regional Sea Programmed to the Abidjan Convention.
Understanding the drivers will inform long-range strategic responses for management and will inform the business case for investment in sargassum use enterprises
The GESAMP is establishing a working group on Sargassum to assist this process. The latest development is that the IOC-Scientific Committee on Oceanic Research (SCOR) GlobalHAB (www.globalhab.info ) is planning for an Open Science meeting on Sargassum to focus at identifying the main research questions to better understand what is driving the Sargassum mass occurences. It is expected to be done jointly with GESAMP (to be confirmed at GESAMP 46). Also, GlobalHAB is partnering with the EU project EuroSea in this initiative.
So here we really need to link what has been discussed this week in Guadeloupe with all these initiatives
Enhance overall collaboration, coordination, and research at global, regional and national levels. Currently there is not coordination and several countries, partners, agencies are duplicating efforts.
Conducting an in-depth regional assessment of socio-economic and environmental impacts and challenges to better comprehend the effective and sustainable management of Sargassum.
Continue to coordinate related initiatives at regional scale and using the integrated approach, continue to collaborate with regional organizations already involved with monitoring the seaweed.
Determine the main sources of pollution and nutrients associated with the increase of Sargassum in pilot areas of the region in collaboration with Universities and Research Institutions.
Development of an early warning system at regional scale with information at national/local levels. Cooperation is already ongoing among UNEP-CEP, SPAW RAC, South Florida University, Texas A & M University and the Intergovernmental Oceanographic Commission from UNESCO.
Development of a ship-based monitoring protocol (observation of Sargassum rafts in the open sea by the maritime fleet including commercial boats) in the Atlantic Ocean.
