The document summarizes several studies on DNA replication and the molecular machinery involved. It describes how researchers used tools like molecular biology and biochemistry to slow down and "freeze" the replication process at intermediate steps. This allowed them to observe conformational changes in proteins like the origin recognition complex (ORC) as it recruits the helicase enzyme to unwind DNA. Cryo-electron microscopy was then used to capture 3D structures of the protein components and reveal how they interact during replication initiation. The studies provide new insights into this critical cellular process.

Biology, genetics, nanotechnology, neuroscience, materials science, biotech, ...Brian Russell
Over the past two years I've done a lot of interesting research which I've decided to aggregate. My research pertains to the following: Biology, Genetics, Nanotechnology, Neuroscience, Materials Science, Biotechnology, Chemical Engineering, All Things 3-D, Super Computing, Quantum Physics, Energy, Design, & Sustainability.
The DNA is the basis of our genetic code, we could almost say that we are all made of DNA; therefore all studies are trying to understand this important part of us. Over time, they have discovered that DNA contains all the instructions that control the development and function of every cell in our body. What we know is that the DNA is able to divide itself, replicating and giving two daughter strands which contain exactly the same information from DNA mother. Then these are transcribed into RNA and finally translated into proteins, this is what we know as the central dogma of genetic information.
Although nature seems to be so perfect there are some cases where this beautiful process fails, and this is where certain diseases are originated and can cause multiple problems. Scientists are increasingly closer to find answers and perhaps their studies can help in the future.
New treatments for Alzheimer's, autism and depression, could be developed.
It could be the starting point for future researches on genes involved in these diseases.
Knowing which genes are involved, people who are not sick yet, might prevent some disease.
These findings help us understand how diseases work and where they come from.
Encourages doctors and scientists to find more about this genes, to achieve excellent results that could benefit many people.
It gives us hope and determination to achieve incredible things in this medicine area; we know that humans are able to find and develop things that we have never imagine.
We know that DNA is the basis of everything, thus if we understand certain parts of it and what is involved on it, we would be able to control many diseases that affects society nowadays.
With these discovery we would be contributing to industry and researches.
new hypothesis could change the way we see things, and would make researchers focused in other cell structures such as ribosomes.
The cause of some diseases might not be in the DNA, but on the malfunctioning of ribosomes, in that way we must look for the real cause of them.
In my opinion this is a big step for medicine, although there is not yet a certain result, and they have to investigate more about the genes, they have a great part of the investigation that can guide them to find the solution to multiple diseases. I think that this kind of researches benefit a lot our society, because they are trying to improve people’s life, by finding the different places of de brain where illnesses are originated. With this project we can start thinking on possible cures and treatments for Alzheimer's, autism, depression and other disorders.
It's good to start investigating on other cellular structures that may be quite involved in the most complex processes of DNA. Scientists may have never wondered what real role of ribosome is. Thinking about new hypotheses and that maybe the ribosome is the central point is crazy but good, because they could be right.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Designing Great Products: The Power of Design and Leadership by Chief Designe...
Molecular biology
1.

3.
4. More complex organisms are composed of
millions of cells, so it is essential to know to
understand the life sciences.
The formation of the earth began about 4.6
billion years, and from there slowly and step by
step was formed everything we see at this time.
Humans are composed of more than 200 different
cells, specialized in various functions that enable
the functioning of our body with a set ready to
face a world
5. The current research picks up where a study
conducted last year left off. That research
determined the structure of a piece of protein
machinery called the "origin recognition complex"
(ORC), which identifies and binds to DNA-
replication "start" sites. When joined by a
replication initiation factor, the ORC undergoes
conformational changes that set in motion the
whole replication process. The new study reveals
how this previous structure recruits and interacts
with the enzyme that eventually unwinds the
DNA double helix into two separate strands.
6. Catching the molecular machinery in action is no
simple task. Intermediate protein structures exist
on fleeting timescales, and the interactions take
place at the atomic level. Researchers working in
Speck and Stillman's labs used tools of molecular
biology and biochemistry to slow down the
process.
They purified and then remixed together pieces of
the protein puzzle (including the origin
recognition complex, the replication initiator, the
core of the helicase, and other components) and a
slow-acting energy agent so the energy-requiring
reaction is unable to proceed to completion.
7. Like dancers paused in place by a sudden stop of
music, the molecular components "froze" partway
through the helicase recruitment/assembly
process.
Jingchuan Sun at Brookhaven then literally froze
the samples, embedding them in ice, and took tens
of thousands of pictures with a cryo-electron
microscope. He then used computer software to
reconstruct the 3-D structure from the 2-D
electron microscope pictures.
8. Comparing the new structure (components of the
helicase bound to the origin recognition complex)
with the structures of the ORC produced last year
revealed conformational changes. Binding of the
helicase core components appears to shift the ORC
into a spiral conformation that closely matches the
spiral shape of double-stranded DNA.
9. It is really wonderful as they could observe the
behavior of these proteins, as well as took benefit
for subjects such as cell division can currently
serve in the treatment of many diseases.
Also, is very important how each of the people
committed to the struggle for finish work research
and thus show excellent results, which are not
easy but not impossible.
10. The answer, says Dr. Mak in research published
today in the Journal of Experimental Medicine, is
found in the way estrogen rushes in to "rescue"
cells whose healthy functioning has been altered
by oxidative stress, a well-established factor in
cancer development. Without estrogen, these
damaged cells would die a natural death and not
threaten the host in the long run, but with
estrogen, these cells not only survive, but thrive
and develop breast and ovarian cancers. In
Canada, about 1,000 women die from BRCA1-
related cancers every year.
11. The research published today illuminates the
interplay between the tumour suppressor gene
BRCA1 and a master regulator -- Nrf2 -- that
governs the antioxidant response in cells. In
healthy cells of all tissues, BRCA1 normally
repairs damaged DNA in partnership with Nrf2,
and so the cells are protected against oxidative
stress. However, when the BRCA1 gene is
mutated, it loses its ability to repair DNA and can
no longer partner with Nrf2, shutting off its
antioxidative function.
12. In most tissues, the resulting oxidative stress kills
the cells that have lost BRCA1 function. However,
in breast and ovary, the estrogen present in these
tissues can swoop in to rescue BRCA1-deficient
cells by triggering a partial turn-on of Nrf2. These
unhealthy cells gain just enough resistance to
oxidative stress to keep them alive and growing.
Over time, these surviving BRCA1-deficient cells
accumulate more and more mutations due to their
lack of ability to repair DNA damage, eventually
leading to the development of cancer in these
tissues.
13. The missing piece of the puzzle was estrogen and
its unexpected effects on the antioxidant
regulation mediated by Nrf2.
The research published today was funded by
grants from the Canadian Institutes of Health
Research, the Ontario Ministry of Health and
Long-term Care, and The Princess Margaret
Cancer Foundation.
14. At present, the breast and ovarian cancer affects
many women in the world, because this is very
important, that prove predisposition forms in
order to "prevent“.
However, this study goes into an ethical and
society, because it can be a way to prevent cancer,
but also pitted against a world that makes facile
way to deliver it to the youth especially, is very
difficult.
15. At this time, medical advances from all eyes but
likewise advancing disease, so if you want to
promote health, we find every day a new thing so
that way we can work with the prevention and
treatment of all the various conflicts that appear
every day.
16. In a medical career will always find puzzles to
solve, issues to investigate and to clarify doubts.
all these studies being conducted continuously
help us make our work simpler and we
understand there are also advances in all areas
Doctors face daily with diseases easily spread in
the population, and yourself from terminal
characteristics for life, for this, do research and
learn about these is not far from reality, and never
left over any issue that has to do with these
17. Be aware about new treatment options and
disease prevention, serves not only to learn, and is
reflected in dealing with the sick and the way it
seeks the welfare for all, this is the reason which
the doctor has to study all his life.
also, is of outstanding importance to know about
more concurrent diseases in the population, so to
be clear, also need to know about every part of our
body and its functioning.
18. Daily, in a medical career and in many others, we
have to face anything new coming out every day,
for this, it is useful to establish contact with the
daily news that is reflected in our knowledge.
Not only important for the medical, also helps to
enrich our language and our way of life, which are
required to complete a professional.
