This document discusses several studies related to feedstocks for aviation biofuels. It provides an overview of major feedstock options globally, including their regional production, challenges to increasing production levels, and forecasts for bioenergy use to 2050. While multiple feedstocks will likely be required, the availability and logistics of feedstocks may be the main determinants in what fuels are produced and where. Significant research, development, and infrastructure investments are still needed to enable aviation biofuels to replace fossil fuels, but there is likely sufficient global feedstock potential if road transport biofuel demand decreases through electric vehicle advancements.

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.
Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.

Repurposing Antibiotic-producing Polyketide
Synthases to Fuels and Chemicals
Outcomes
• We have repurposed PKSs to produce a number of short-chain
molecules that could have applications as fuels or chemicals.
• We have uncovered a number of expanded substrate
specificities and requirements of various PKS domains not
previously reported and determined an unexpected difference in
the order of enzymatic reactions within a module.
• We were able to efficiently change the stereochemistry of side
chains in selected PKS products.
Yuzawa, S. et al., (2016) “Insights into polyketide biosynthesis gained from repurposing antibiotic-
producing polyketide synthases to fuels and chemicals” J Antibiot (Tokyo) DOI: 10.1038/ja.2016.64.
Background
• Complex polyketides comprise a large number of
natural products that have broad application in
medicine and agriculture.
• They are produced in bacteria and fungi from enzyme
complexes named type I modular polyketide synthases
(PKSs) that contain discrete enzymatic domains
organized into modules.
• The modular nature of PKSs has enabled a multitude
of efforts to “repurpose” the PKS genes to produce
novel compounds in a predicted manner.
Significance
• These results greatly enhance the mechanistic
understanding of PKS and pave the way for exploitation
of PKS as a platform to produce fuels and chemicals.

5. Feedstocks for aviation biofuels.
Chuck, Singh et al. (2016). "Biofuels for Aviation, Chapter 2
(pgs. 17-34), Elsevier ISBN: 978-0-12-804568-8.
Background
• Collaboration between researchers at the University of Bath-UK,
Plymouth Marine Lab-UK and JBEI-USA to understand the cost,
availability and sustainability of feedstocks to successfully produce
aviation biofuels.
• There are numerous routes to aviation fuels and as such it is likely
that multiple feedstocks will be used globally to produce future
aviation biofuels.
• The chapter provides a general overview of all the major feedstocks
available, where they are regionally produced, the challenges
inherent in increasing production to necessary levels and key
forecasts for bioenergy use ahead to 2050.
Significance
• While the properties of the fuel itself is key to the eventual
replacement of fossil resources, it is more likely that the availability
and logistical consideration around the feedstock will be the key
determinant in what fuels are produced and where they are
situated.
• While a large investment must still be made in research
development and infrastructure to make aviation biofuels a reality,
there is probably sufficient feedstock to produce aviation biofuels if
the demand for road transport biofuels is reduced by significant
technological advancements in electric and battery technology.
• It is also clear that no one feedstock will supply the entire aviation
sector, and a range of technologies to develop aviation biofuels
from lipids, lignocellulose, marine resources will need to be
developed concurrently to create aviation biofuels.
• Prediction on whether a paradigm shift due to genetic engineering
or the development of 3rd generation, non-land based biomass, will
alter the biofuel market is difficult with current data.
