Climate models require supercomputers with immense computing power and cooling capabilities. They contain over 2 million lines of code to calculate physical laws governing the Earth like cloud formation, sunlight wavelengths, forest fires, and more. They can accurately identify past and present climates, and predict future climates. Carbon dioxide from burning fossil fuels can remain in the atmosphere for hundreds of years, contributing to cumulative global warming effects observed today according to climate model data.

Of Leslie (of ‘Leslie in California’ and Carla (‘in ‘Trespass’), with whom do we sympathize more and why?
The essay will be graded on:
· clarity and conciseness,
· organization,
· grammar, spelling and punctuation,
· quality of content.
Please WRITE CLEARLY and DOUBLE SPACE.
It must include MLA referencing. www.easybib.org is a website you can go to get bibliographical information put into the right format.

Tips for Writing Comparison/Contrast Essays
1. Be sure to introduce BOTH stories, in your opening paragraph, and also to tell the reader what the stories have in common that makes it possible to compare them.
2. Make sure that you do actually compare/contrast the stories (for example, ‘Tim, unlike Montresor, kills because it is his job to.’) This will ensure that you end up with a single, cohesive essay, not two mini-essays sitting on top of each other.
3. Make sure that you deal with the things you are comparing (in this case two characters) at equal length.

Assignment 2The Global Environment: An Emerging World View (cont.)
Reading Assignment:
Read Article 5, A safe operating space for humanity by Johan Rockstrom et al. on pages 36-41 in your textbook.
Overview:
This lesson will illustrate understanding of how locally-based activities influence global phenomena as climate change. You will also observe that in a time of disappointing progress is occurring in global initiatives to curb greenhouse gas emissions, one of the most promising paths might be a localized action.
The authors identified planetary boundaries that must not be crossed in order to avoid significant environmental degradation.
Of the 10 factors considered, 3 of them--biodiversity loss, climate change,and agricultural pollution--have already crossed the threshold for a sustainable planet.
Evidence so far suggests that, as long as the thresholds are not crossed, humanity has the freedom to pursue long-term social and economic development.
Topics Covered:Planetary BoundariesClimate ChangeRate of Biodiversity LossNitrogen and Phosphorus CyclesDelicate Balance
Key Terms:
Planetary Boundaries -- boundaries that define the safe operating space for humanity with respect to the Earth system and are associated with the planet’s biophysical subsystems or processes.
Holocene -- the unusually stable environment of the planet for the past 10,000 years, which has seen human civilizations arise, develop, and thrive.
Anthropecene -- an era that has arisen since the Industrial Revolution, in which human actions become the main driver of global environmental change.
EPA -- Environmental Protection Agency (www.epa.gov) for more information.
Greenhouse Gas (GHG)-- an atmospheric gas such as carbon dioxide, water vapor, or methane that easily absorbs infrared radiation & gives off heat, some of it directed toward space & the rest toward Earth.
Carbon Cycle -- the cycle of CO2 in the Earth‘s ecosystem; photosynthetic organisms transform the gas into organic nutrients, which are then restored to a gaseous state by respiration & decay. Instructor's Comments:
Fact 1: Currently, atmospheric CO2 concentration is 31% higher than in 1750, a level that has not been exceeded during the last 420,000 years.
Fact 2: The primary cause is human activity, particularly fossil fuel use & deforestation leading to further increases in CO2.
As we have seen a similar trend in the previous lesson, the following graph illustrates the CO2 concentration (dashes) and the global surface Ts (solid line)
Fact 3: Burning fossil fuels in power plats and automobiles ejects poisonous particles & gases that alter the chemical structure of the Atmosphere.
Fact 4: Worldwide CO2 emissions from burning fossil fuels (coal, oil, and natural gas) reached a record 30.6 Billion metric tons in 2010 that economists and scientist call this as “a wake-up call”. (Source: Int.

Richard's aventures in two entangled wonderlandsRichard 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.
Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
(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.

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.

1. Climate Models
It takes up the space of an entire industrial building, and inside, it looks like as though
there are rows and rows of tall identical bookshelves stacked tightly against each other. But these
aren’t bookshelves; together, these clusters of connected processors compose a supercomputer.
The supercomputers, with its many servers, is capable of incredible computing power; it
also requires intense cooling.
Currently, it is churning out the calculations of a global climate model; this climate model,
like many others, are on average contains 2 million lines of code – far beyond what a human
mind can complete. At the core of the climate model is the basic law of thermodynamics; it’s
also calculating the many physical laws that governs our Earth such as cloud and ice formation,
wavelengths of sunlight, forest fires, nutrient cycles, pollution, water vapor, ocean tides, energy
use such as electricity across many cities, and more. It is able to accurately identify climate from
the past and the present, and even predict the climate of the future.
Carbon dioxide is the primary cause of global warming that we are observing today. There
are two sources of carbon dioxide. First, there are natural sources of carbon dioxide such as
water vapor and volcanic ashes; these tend to have a short lifespan and say in the atmosphere at
an average of seven to a hundred days. Carbon dioxide that is emitted from the burning of fossil
fuels however can stay in the atmosphere for a 100 to 1000 years; and hence, the effect is
cumulative.
With climate models – based on data – we can be confident about the trends in climate
change and identify the causes that has led to a unprecedented rise in global surface temperature.
