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.
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.
(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.
Professional air quality monitoring systems provide immediate, on-site data for analysis, compliance, and decision-making.
Monitor common gases, weather parameters, particulates.

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.
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.

3. INTRODUCTION
Climate change is a change in the statistical distribution of weather patterns
when that change lasts for an extended period of time (i.e., decades to millions
of years). Climate change may refer to a change in average weather conditions,
or in the time variation of weather around longer-term average conditions (i.e.,
more or fewer extreme weather events). Climate change is caused by factors
such as biotic processes, variations in solar radiation received by Earth, plate
tectonics, and volcanic eruptions. Certain human activities have been identified
as primary causes of ongoing climate change, often referred to as global
warming.
4. Carbone dioxide
The amount of carbon dioxide in the atmosphere needs to be lowered
and the issue must be addressed from many different angles. Reduction of
releases is the most important issue, but there are also alternative ideas to achive
this goal. There are both natural and human sources of carbon dioxide emissions.
Natural sources include decomposition, ocean release and respiration. Human
sources come from activities like cement production, deforestation as well as the
burning of fossil fuels like coal, oil and natural gas.Due to human activities, the
atmospheric concentration of carbon dioxide has been rising extensively since
the Industrial Revolution and has now reached dangerous levels not seen in the
last 3 million years.1 2 3 Human sources of carbon dioxide emissions are much
smaller than natural emissions but they have upset the natural balance that
existed for many thousands of years before the influence of humans.
5. Carbon Dioxide Emissions:
Natural Sources
Apart from being created by human activities, carbon dioxide is also released into the
atmosphere by natural processes. The Earth's oceans, soil, plants, animals and volcanoes are
all natural sources of carbon dioxide emissions.Human sources of carbon dioxide are much
smaller than natural emissions but they upset the balance in the carbon cycle that existed
before the Industrial Revolution. The amount of carbon dioxide produced by natural sources
is completely offset by natural carbon sinks and has been for thousands of years. Before the
influence of humans, carbon dioxide levels were quite steady because of this natural
balance. 42.84 percent of all naturally produced carbon dioxide emissions come from ocean-
atmosphere exchange. Other important natural sources include plant and animal respiration
(28.56%) as well as soil respiration and decomposition (28.56%). A minor amount is also
created by volcanic eruptions (0.03%).
6. Carbon Dioxide Emissions:
Human Sources
Since the Industrial Revolution, human sources of carbon dioxide emissions
have been growing. Human activities such as the burning of oil, coal and gas, as
well as deforestation are the primary cause of the increased carbon dioxide
concentrations in the atmosphere.87 percent of all human-produced carbon
dioxide emissions come from the burning of fossil fuels like coal, natural gas and
oil. The remainder results from the clearing of forests and other land use changes
(9%), as well as some industrial processes such as cement manufacturing (4%).
7. Carbon sequestration
Carbon sequestration is the process involved in carbon
capture and the long-term storage of atmospheric carbon
dioxide. Carbon sequestration involves long-term storage of
carbon dioxide or other forms of carbon to mitigate or defer
global warming. It has been proposed as a way to slow the
atmospheric and marine accumulation of greenhouse gases,
which are released by burning fossil fuels.
8. Consumption
Is reducing energy consumption important for climate change?
It is natural to think that reducing our energy consumption is good for the
climate. We can ride a bicycle instead of driving a car. And if we drive a car, we
can drive a smaller, more fuel-efficient car. These things certainly help reduce
urban noise, congestion, and air pollution. But do they really help to solve climate
change?
9. De-carbonization is key
There are many ways to reduce our energy demand through lifestyle choices
and improved efficiency, with broad environmental and social benefits. But we
should not fool ourselves into thinking that by doing these things, and these
things alone, we necessarily help to solve climate change. We can only solve
climate change by replacing fossil fuels with other sources of energy.
The good news is that these other energy sources exist, and are already
beginning to compete with fossil fuels on an even footing. Our energy
consumption choices can help to accelerate their adoption. Every switch from oil
to electricity, whether in mobility or home heating, matters. Some of those
choices may involve using less energy, but others may involve using more. To
stop climate change it is far more important where our energy comes from than
simply how much of it we use.
10. Deforestation
Deforestation, clearance or clearing is the removal of a forest or stand of trees
where the land is thereafter converted to a non-forest use.Examples of
deforestation include conversion of forestland to farms, ranches, or urban use.
The most concentrated deforestation occurs in tropical rainforests. About 30% of
Earth's land surface is covered by forests.
The removal of trees without sufficient reforestation has resulted in damage to
habitat, biodiversity loss and aridity. It has adverse impacts on biosequestration of
atmospheric carbon dioxide.
11. Causes for deforestation
The degradation of forest ecosystems has also been traced to economic
incentives that make forest conversion appear more profitable than forest
conservation.Many important forest functions have no markets, and hence, no
economic value that is readily apparent to the forests' owners or the communities
that rely on forests for their well-being.From the perspective of the developing
world, the benefits of forest as carbon sinks or biodiversity reserves go primarily
to richer developed nations and there is insufficient compensation for these
services. Developing countries feel that some countries in the developed world,
such as the United States of America, cut down their forests centuries ago and
benefited economically from this deforestation, and that it is hypocritical to deny
developing countries the same opportunities, i.e. that the poor shouldn't have to
bear the cost of preservation when the rich created the problem.
12. Some commentators have noted a shift in the drivers of deforestation over the past 30
years.Whereas deforestation was primarily driven by subsistence activities and
government-sponsored development projects like transmigration in countries like
Indonesia and colonization in Latin America, India, Java, and so on, during the late 19th
century and the earlier half of the 20th century, by the 1990s the majority of
deforestation was caused by industrial factors, including extractive industries, large-
cale cattle ranching, and extensive agriculture.
Experts do not agree on whether industrial logging is an important contributor to
global deforestation. Some argue that poor people are more likely to clear forest because
they have no alternatives, others that the poor lack the ability to pay for the materials
and labour needed to clear forest. One study found that population increases due to high
fertility rates were a primary driver of tropical deforestation in only 8% of cases.
