If the Moon suddenly vanished:
- Earth's axis would lose stability and wobble dramatically, causing extreme temperature changes and unpredictable seasons.
- Tides would be much smaller, caused only by the Sun, disrupting marine life and coastal ecosystems.
- Earth's rotation would speed up, with day lengths shortening to 8-10 hours and winds of 160-200 km/h sweeping the surface.
- Life on Earth would struggle to adapt to the entirely different environmental conditions without the stabilizing influence of the Moon.

The phenomenon of the super-Moon that occurs at the moment led me to elaborate this article to show the importance of the Moon for life on the planet Earth. The Earth was formed about 4.6 billion years ago, from the disk of gas and dust that formed the Sun and the other bodies of the Solar System. The Moon was formed about 100 million years after Earth, after a violent impact of a body of the size of Mars, called Theia. The fragments that resulted from the clash between Earth and Theia formed the Moon. The Earth-Moon system began to exert a mutual gravitational attraction. Such an attraction has produced (and continues to produce) the dissipation of an enormous amount of energy from the friction of the oceans with the seabed during the tides' comings and goings. As a consequence of such dissipation, the Earth's rotation speed was reduced from about 6 hours, which lasted the primitive earth day without Moon until the current 24 hours. What would happen to the Earth if the Moon were continually moving away? What would happen if the Moon suddenly disappeared? These issues are addressed in this article.
In this presentation, one will find more elaborative and detailed information on the topic of TIDES with full depth knowledge about its various aspects including the forces that act on it, how & when they act on it with illustrative images.
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.

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.

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.
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.

Life without the Moon
Ana Rodrigues

A scientific speculation
2. The Moon has always been present in our lives and most of us are
not aware of its importance.
This article provides information about:
the effect of the Moon on Earth;
what would our planet be like without the Moon;
what would happen to Earth if the moon suddenly vanished?
The Moon
3. Origin of the Moon
The Moon is thought to have formed in a high-speed impact, when a
body the size of Mars (Theia) slammed into the young Earth about
4.5 billion years ago. The resulting molten rock, vapor and shattered
debris^mixed with debris from Earth to form a ring around our planet.
Over time, this debris coalesced to make the Moon.
4. What would have happened on Earth if, about 4.5 billion years ago,
Theia had passed peacefully on its way without striking Earth and
forming a moon?
If the Moon had never formed, Earth would be a very, very different
place.
What if we had never had a moon?
5. The gravitational attraction between
Earth and the Moon stabilizes the tilt
of Earth’s axis.
It is today’s constant tilt of 23.5°
that gives Earth its climate and seasons.
The tilt of Earth’s axis
6. Without the Moon, Earth would be subjected to the pull of the
other planets and the stability of Earth’s axis would be lost .
Its axis would wobble, resulting in dramatic changes in its
temperature, climate and seasons:
When Jupiter was close, it would pull Earth in one direction;
When Mars was close, it would pull in another direction.
The tilt of Earth’s axis
7. Both the Moon and the Sun are involved in the tides, as they exert
their gravitational pull on Earth, causing the oceans to bulge towards
the Moon. Another bulge occurs on the opposite side, since Earth is
also being pulled toward the Moon.
When the Moon and the Sun are aligned (at new moon, or full moon),
their combined gravitation pull is strongest and the high tides (A)
are highest.
Tides
8. When the Moon is in its first quarter (D) or third quarter (E), the high
tides are lowest.
Because Earth spins, the high tides occur twice daily at one spot.
Without the Moon, and although our seas would still be tidal,
the tides would be much smaller – caused only by the Sun.
Tides
9. When Earth rotates, there is a friction force (F) between land and the
water (under the gravitational pull of the Moon) that acts as a brake,
slowing the rotation of Earth and lengthening the Earth day to 24 h.
Without the Moon, an Earth day would be only 8-10 h long.
The faster rotation would cause winds of 160-200 km to sweep
Earth’s surface.
Rotation of Earth
10. We and all other organisms on Earth would be in serious trouble if
the Moon just vanished tomorrow : we have evolved to live under a
particular set of conditions and would then be faced with an
entirely different environment.
What if our Moon suddenly vanished?
11. With the lack of stability in Earth’s tilt the temperatures would rise,
the ice from the poles would melt and the oceans would rise,
changing the coastlines all around the world. Countries like the
Netherlands would be covered in water.
What if our Moon suddenly vanished?
12. With the lack of stability in Earth’s tilt, we would also lose our regular
seasons. Think how many organisms grow, mate, migrate or hibernate
at particular times of year. And drastic changes in temperature would
affect the growing season and climate for plants, making food
production for the billions of people on Earth more complex.
What if our Moon suddenly vanished?
13. Marine turtles tend to lay their eggs at spring tides, when the highest
high tides occur. These tides allow the female turtles to swim up the
beach to lay their eggs above the high-water mark (where they hatch
best). What effect might the loss of the Moon, and of the high tides ,
have on these turtles?
What if our Moon suddenly vanished?
14. Jellyfish and many other groups of marine and freshwater zooplankton
move up and down the water column according to a daily rhythm.
If the Moon were to disappear, Earth days would become shorter and
the animals would need to adapt to the shorter daily rhythm.
What if our Moon suddenly vanished?
15. Columbia University Professor Arlin Crotts explains in this video
what a world without the moon would be like.
What if our Moon suddenly vanished?
