A Visit to Nature History Museum of LA
Introduction
After visiting the Los Angeles Natural History Museum, I learned so many things concerning the animals that were there in the early days and how they looked like, as well as, how they lived . The Museum has a large paleontological collection that helped me develop a better understanding of the Earth’s biota. The Museum’s collection ranges from fossils to the modern organisms which are collected from the entire world, and it is therefore a good place to begin with when exploring on the paleontological exhibits and other historical items. During the visit at the Museum I learned of a few things that I never knew existed and other facts too that are new. In this article there are a lot of areas and information that are presented showing all the paleontological exhibits and other historical items.
Exhibit 1. The Gray Fox
The gray fox (Botanical name Urocyon cinereoargenteus) is one of the interesting exhibits I found at the museum. The exhibit on Fray Fox features 4 photographs indicating how the small American mammal survives in the wild. The photograph below (Image 1) shows a Gray Fox family in their burrow. It reflects the legacy of life by clear illustrations of how the Gray Fox adapts to the environment. From what I gathered, the animals are largely monogamous. The photograph shows an ideal family in their broken terrain habitat. Gray foxes opt to live in broken terrain and rocky areas in order to ease the process of making new homes.
An adult male is seen overlooking his family that is resting outside their den, probably to show gender roles in the social life of the gray fox. The female (much smaller than the male) lies next to their kit. The fresh soil dug in their burrow shows that their home may be new, indicating that the species may have moved in more than once. Gray foxes diet is comprised of vegetation, small mammals such as mice, and insects. The photograph captures an environment (San Gabriel Mountains, California) capable of meeting the species food needs. Green vegetation provides gray foxes with vegetation foods. Insects feeding on the vegetation are most likely part of the gray fox’s diets. Gray foxes are spread across central USA, Southern Eastern Canada, and Western Venezuela (Reid, 2016).
Information obtained from (Reid, 2016) indicates that one of the most peculiar traits of the gray fox is their ability to climb trees in order to evade predators. The strong claws used to dig and remove earth are used to climb trees. This makes them the only species of the dog family with the ability to climb trees.

(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 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.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.
Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.
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.

3. DANDELION – FRENCH DENT DE LION
• From the Devonian period about 385-359 MYA. (Willis,
McElwain)
• Dandelions are, quite possibly, the most successful plants
that exist, masters of survival, worldwide.
• They are the oldest of flowers dating back to early the
Egyptians. (Hanrahan)
• If you mow dandelions, they’ll grow shorter stalks to spite
you.
• They do not need pollination. That means if you have one in
your yard over time you could have millions. ( Hanrahan)
4. YOU PROBABLY SAYING TO YOURSELF " I HOPE THAT IS NOT HER HOME!"
AND I'M SAYING "I HOPE THAT THIS IS NOT YOUR HOME!"
THE TRUTH IS THAT DANDELIONS CAN OVERTAKE ANY HOME GARDEN IF LEFT NOT TREATED.
THEY ARE MASTERS OF EVOLUTION.
5. LODGE POLE PINE TREE- PINUS CONTORTA GINKGO - CLOSEST LIVING RELATIVE TO GYMNOSPERMS
o ALL PINE TREES CAME FROM GYMNOSPERMS FROM THE TRIASSIC PERIOD 200-250 MYA.
o THE LODGE POLE PINE IS A RESILIENT TREE THAT ADAPTS WELL TO DROUGHT CONDITIONS
o LODGEPOLE PINE GROWS ON SOILS THAT VARY WIDELY BUT ARE USUALLY MOIST. GROWTH IS BEST WHERE SOIL PARENT
MATERIALS ARE GRANITES, SHALES, AND COARSE-GRAINED LAVAS (DESPAIN)
o THE 3–7 CM CONES OFTEN NEED EXPOSURE TO HIGH TEMPERATURES (SUCH AS FROM FOREST FIRES) IN ORDER TO OPEN AND
RELEASE THEIR SEED (FEDUCK)

7. BREWERS BLACKBIRD
From the Cenozoic period 65-0 MYA
Brewer’s Blackbirds are social birds that nest in colonies of
up to 100 birds. (Martin, Stephen G. 2002)
Brewer’s Blackbirds are quick to notice new food sources
and have been credited with helping to curb outbreaks of
insect pests
I have seen that they protect their young by swooping down
at the back of the head of humans or animals that get close.
When they swoop, they get really close!
8. PICTURE OF NEST WAS TAKEN IN MY BACK YARD-SOUTH LAKE TAHOE, CA
We also note that many all-black species of blackbirds nest
in open habitats that are not marshes (e.g., Brewer's
blackbird in savannas. Thus, it seems unlikely that
openness of habitat per se is a major factor driving the
evolution of plumage patches in marsh-nesting blackbirds
(Orians, 1985).
The female is the one that makes the nest out of small sticks
and other material found close.
I risked my life to get this picture!
9. THE FIRST PICTURE BELOW IS ONE OF GRANITE THAT WAS CHIPPED TO FORM RECTANGULAR BLOCKS THAT CAN BE USED FOR
RETAINING WALLS AND LANDSCAPE DECORATION
ALL GRANITE EXPOSED ON THE SURFACE OF THE EARTH HAD TO BE UPLIFTED FROM DEPTH, USUALLY FROM ABOUT ONE TO 20 MILES
DOWN.
GRANITE IS RADIOACTIVE. LIKE MANY OTHER NATURAL MATERIALS, IT CONTAINS TRACE AMOUNTS OF URANIUM. SOME GRANITE
BODIES, HOWEVER, CAN HAVE 5 TO 20 TIMES THE NORMAL AMOUNT OF URANIUM, THE BYPRODUCT OF WHICH IS RADON GAS,
WHICH HAS BEEN SHOWN TO CAUSE LUNG CANCER
10. PINK GRANITES OWE THEIR COLOR TO RED OR PINK ALKALI FELDSPARS
THE SIERRA NEVADA MOUNTAINS ARE ABUNDANT IN GRANITE ROCK FORMATIONS
30 MILLION YEARS AGO, DURING AN EPISODE GEOLOGISTS CALL A MAGMATIC FLARE-UP. DURING THIS TIME, AN OCEANIC PLATE
THAT HAD BEEN SLIDING UNDERNEATH NORTH AMERICA BROKE APART, EXPOSING THE BOTTOM OF THE NORTH AMERICAN
CONTINENTAL PLATE TO HOT MANTLE ROCKS. THIS HEATING CREATED NEW POCKETS OF MAGMA, AND EVENTUALLY BODIES OF
GRANITE CALLED PLUTONS ACROSS THE AMERICAN WEST. (ALLEN)
GRANITE BOLDER-IGNEOUS ROCK HALF DOME-YOSEMITE NATIONAL PARK
11. SCORIA IS A DARK-COLORED IGNEOUS ROCK WITH ABUNDANT ROUND BUBBLE-LIKE
CAVITIES KNOWN AS VESICLES. IT RANGES IN COLOR FROM BLACK OR DARK GRAY TO DEEP
REDDISH BROWN. SCORIA USUALLY HAS A COMPOSITION SIMILAR TO BASALT, BUT IT CAN
ALSO HAVE A COMPOSITION SIMILAR TO ANDESITE. (MCPHEE, DOYLE, ALLEN)
MANY PEOPLE BELIEVE THAT SMALL PIECES OF SCORIA LOOK LIKE THE ASH PRODUCED IN A
COAL FURNACE. THAT HAS RESULTED IN PARTICLES OF SCORIA BEING CALLED "CINDERS"
AND THE SMALL VOLCANOES THAT ERUPT SCORIA TO BE CALLED "CINDER CONES."

STUMP WAS REMOVED . NOW USED IN
MY LANDSCAPE
RHYOLITE WITH MULTIPLE VUGS FILLED
WITH GEMMY TRANSPARENT ORANGE
FIRE OPAL.
Trapped gases often produce vugs in the rock.
18. ANGULAR UNCONFORMITY
THESE ARE FORMED FROM UPHEAVALS THAT TILT THE LOWER ROCKS AND FORM MOUNTAINS THAT WERE THEN WORN AWAY AND
COVERED BY YOUNGER, FLAT-LAYING ROCKS.(MONROE AND WICANDER)
19. PRINCIPLE OF
INCLUSION
THIS IS THE SAME PICTURE FROM THE SLIDE BEFORE
THIS TIME WE ARE LOOKING AT THE PRINCIPLE OF
INCLUSION (SORRY DON'T HAVE A CLOSE UP).
IN IT YOU CAN SEE THE SMALL BOULDERS THAT ARE
TRAPPED FROM THE VOLCANIC ERUPTION THAT OCCURRED
MILLIONS OF TEARS AGO. THE TRAPPED BOULDERS HAD TO
HAVE EXISTED BEFORE THE ERUPTION BECAUSE THEY ARE
NOW TRAPPED IN THE ROCK LAYERS.
THIS IS THE PRINCIPLE OF INCLUSION.
