Jane Goodall was born in London in 1934 and has devoted most of her life to studying chimpanzees in Gombe Stream National Park. Her research revealed that chimpanzees display affectionate behaviors like hugging and kissing to bond, and that they are omnivorous and sometimes practice cannibalism. These findings changed the understanding of animal intelligence and behavior. Over her career, Goodall has received many honors for her scientific work and rehabilitation of chimpanzees, including a Ph.D. from Cambridge University.
In 1960 Jane Goodall pioneered the study of chimpanzees in the wild, showing the world how similar chimpanzee behavior is to that of humans, and helping to demonstrate the close evolutionary relationship of the two species.

21 Pros and Cons of Zoos
June 4, 2017 by
Louise Gaille
Zoos go by several different official names. They can be called “animal parks,” “menageries,” or “zoological gardens.” Despite the different names, each offers visitors the chance to view animals that are confined in an enclosure. Many zoos have breeding programs in place to help eliminate genetic bottlenecks, especially when dealing with an endangered species.
Zoos have been part of our human history from the very beginning when early humans began documenting what happened to them. One of the oldest known zoos was discovered in Egypt in 2009 and was believed to have existed in 3,500 BC. Evidence of elephants, wildcats, baboons, and hippopotami were discovered at the location.
The benefit of having a local zoo is that it gives people an opportunity to learn more about the animals and nature. It is a way to engage children in science, bring families together, and help save certain animal species that are close to extinction.
As for the disadvantages of a zoo, the facilities that are offered can be abused for personal or political gain. One of the earliest zoos in the Western Hemisphere didn’t feature animals. It featured people that had different physical traits, such as having dwarfism or albinism. Even the Catholic Church has a zoo which feature a collection of people from different races and tribes as late as the 16th century.
Ota Benga was part of a human exhibit at zoos in the United States as late as 1906, in St. Louis and the Bronx Zoo.
The pros and cons of zoos are important to consider from a modern standpoint. Our views about zoos may have changed, but is it still ethical to support animal captivity?
What Are the Pros of Having Zoos?
1. Zoos provide an educational resource.The modern zoo plays a critical role in education children and families about the different animals with whom we share this planet. Staff from a zoo will travel to local schools to make presentations, offer special programs on the zoo grounds, and partner with community providers to extend educational opportunities to everyone. No matter what a person’s socioeconomic status may be, there is a chance to learn something new because of the work of a zoo.
2. A zoo provides a protected environment for endangered animals.There are several animals which are poached frequently because of certain items. Having a zoo provides these animals with a safer place to live because they are behind multiple levels of protection. Although poachers have been able to break into zoos to take animals in the past, this is not a frequent occurrence and is normally not successful when it does occur.
3. Zoos can provide a place for the humane treatment of rare animals.One of the best examples of this is the Przewalski horse. In 1945, there were 13 horses that were captured from the wild and placed into a zoo. The last Przewalski horse was seen in the wild in 1966. Because of extensive breeding programs and an effort to reint.
Wildlife refers to undomesticated animal species, however has come to encompass all organisms that develop or live wild in an area without being introduced by humans.
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.

Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.
(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.
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.
Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.

1. Jane Goodall
Valerie Jane Morris-Goodall
born in Hampstead, London, on
the 3rd of April 1934.
Goodall has devoted most of her life to the study of chimpanzees, specifically those in the gombi stream national park, and
largely to their behavoural patterns and emotional depth. She has been credited with numerous findings including evidence
that, like humans, chimps can also perform affectionate actions such as hugging, kissing, and tickling to achieve a greater
bond between members of the troop, and also that chimps are not vegetarian but are in fact omnivours whom sometimes
even partake in cannibalisation. Her discoveries of these behavioural instincts in chimpanzees changed human understanding
of all animals as it posed the question of how intelligent were other common known animals and how can an animals level of
intelligence be understood.
Over the decades Goodall has been awarded with numerous medals and
commendations for both her scientific discoveries and her rehabilitation programs for
chimps who have lost their parents to poaching on behalf of the bushmeat trade.
Among her awards include the Kyoto prize-1990, the Hubbard medal-1995, Tyler prize
for environmental achievement-1997, and a DBE-2004. She was also awarded with a
Ph.D. in ethology but the University of Cambridge in 1965. Jane at the Jane Goodall Gombe Stream
National Park, where she conducted most
of her study of Chimpanzees.
