Introduction
Energy is essential for life to exist in any environment. As humans, we consume huge quantities of energy
every day. This, however, comes with many consequences. Although energy is abundant everywhere, useful
energy is much more difficult to produce and less efficient for our daily activities. Over 90% of produced ener-
gy comes from non-renewable resources. These include oil, natural gas, coal, and uranium. Not only are our
sources of fossil fuels and other nonrenewable energy sources depleting, but many of these sources produce
toxins that are harmful to our bodies and the environment. Fossil fuel depletion, deforestation, pollution, and
global warming are just a few negative effects that come from the combustion of many nonrenewable energy
sources.
Non-renewable Sources
Oil is derived from the remains of plants and animals that lived in aqueous
environments millions of years ago. Over very long periods of time, the
heat from the Earth’s core and the pressure from the sand, silt, and rock
that deposited on top of it turns the remains into crude oil. Scientists and
engineers explore areas to find rocks that indicate the presence of oil un-
derneath, and drill through them to tap into the reservoir holding the yel-
lowish-black substance. After the oil is drilled, it is sent to a refinery to be
separated into usable petroleum products—most of which are used to pro-
duce energy. These include: heating oil, jet fuel, heavy fuel oil, liquefied
petroleum gases, and gasoline.

• Crayons
• Dishwashing liquid
• Eyeglasses
• CDs and DVDs
• Tires
• Ammonia
• Artificial heart valves
Coal is another nonrenewable energy source that is derived from sedimentary rock comprised mainly of car-
bon and hydrocarbons. It takes millions of years to create and forms from dead plants that became trapped
under dirt and water. There are four main types of coal: anthracite, bituminous, subbituminous, and lignite.
Coal is classified into these groups based on the amount of carbon it contains. When coal is buried less than
200 feet underground, surface mining technologies can be used to extract it. However, it if is deeper than 200
feet, underground mining is performed to reach and extract the coal. More than 90% of the coal mined in the
US is used for generating electricity. Even though coal is an inexpensive fuel source, it is important to re-

THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
(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.
The increased availability of biomedical data, particularly in the public domain, offers the opportunity to better understand human health and to develop effective therapeutics for a wide range of unmet medical needs. However, data scientists remain stymied by the fact that data remain hard to find and to productively reuse because data and their metadata i) are wholly inaccessible, ii) are in non-standard or incompatible representations, iii) do not conform to community standards, and iv) have unclear or highly restricted terms and conditions that preclude legitimate reuse. These limitations require a rethink on data can be made machine and AI-ready - the key motivation behind the FAIR Guiding Principles. Concurrently, while recent efforts have explored the use of deep learning to fuse disparate data into predictive models for a wide range of biomedical applications, these models often fail even when the correct answer is already known, and fail to explain individual predictions in terms that data scientists can appreciate. These limitations suggest that new methods to produce practical artificial intelligence are still needed.
In this talk, I will discuss our work in (1) building an integrative knowledge infrastructure to prepare FAIR and "AI-ready" data and services along with (2) neurosymbolic AI methods to improve the quality of predictions and to generate plausible explanations. Attention is given to standards, platforms, and methods to wrangle knowledge into simple, but effective semantic and latent representations, and to make these available into standards-compliant and discoverable interfaces that can be used in model building, validation, and explanation. Our work, and those of others in the field, creates a baseline for building trustworthy and easy to deploy AI models in biomedicine.

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.
3. Renewable energy is generally defined as
energy that comes from resources which are
naturally replenished on a human timescale
such as sunlight, wind, rain, tides, waves,
and geothermal heat.
4.
5. Most non-renewable energy sources are fossil
fuels: coal, petroleum, and natural gas. Carbon
is the main element in fossil fuels. For this
reason, the time period that fossil fuels
formed (about 360-300 million years ago) is
called the Carboniferous Period.
6. Solar energy is radiant light and
heat from the Sun harnessed using
a range of ever-evolving
technologies such as solar heating,
photovoltaics.
7. A solar cell, or photovoltaic cell, is an electrical
device that converts the energy of light directly
into electricity by the photovoltaic effect.
8. Photovoltaic effect
The photovoltaic effect is the creation
of voltage or electric current in a
material upon exposure to light and is
a physical and chemical phenomenon
15. 1. Solar energy is free.
2. Solar energy does not cause pollution.
3. Solar energy can be used in remote areas where it is
too expensive to extend the electricity power grid.
4. Many everyday items such as calculators and other
low power consuming devices can be powered by solar
energy effectively.
5. It is estimated that the worlds oil reserves will last
for 30 to 40 years. On the other hand, solar energy is
infinite (forever).
17. 1. Solar energy can only be harnessed when it is daytime
and sunny.
2. Solar collectors, panels and cells are relatively expensive
to manufacture.
3. Solar power stations can be built but they do not match
the power output of similar sized conventional power
stations. They are also very expensive.
4. In countries such as the UK, the unreliable climate
means that solar energy is also unreliable as a source of
energy. Cloudy skies reduce its effectiveness.
5. Large areas of land are required to capture the suns
energy. Collectors are usually arranged together especially
when electricity is to be produced and used in the same
location.
6. Solar batteries are large and heavy and need storage
space. They also need replacing from time to time.
