Eran las doce y media del mediodía del viernes 22 de noviembre de 1963, las siete y media de la tarde en España, cuando el presidente de Estados Unidos, John F. Kennedy, caía asesinado en Dallas (Texas).
En pocos minutos, la noticia corrió de un confín a otro del globo terráqueo. Y el impacto mediático fue tal, que prácticamente nadie que siga hoy con vida, ha olvidado lo que sucedió aquel día, ni qué hacía, dónde estaba o con quien iba, cuando conoció el suceso.

Globale view:
The Cold War began to form after World War II. The disagreements started between 1947-1951. The world split into two large organizations NATO (North Atlantic Treaty Organization) and the Warsaw pact. Many people believed at that time that a nuclear war would start. The main tensions were between The Soviet Union (Russia) and The United States. Both sides and their allies were building up their weapons but did not use them. It was a fight between political systems for power.
Important people:
Nikita Kruschev (1894->1971)
John F. Kennedy (1917->1963)
Ronald Reagan(1911->2004)
Mikhail Gorbachev(1931-> )
Nikita Kruschev (1894-1971)
Nikita Kruschev was born on April 17, 1894 and died on September 11, 1971. After Joseph Stalin died Nikita Khrushchev became chief director of the Soviet Union. He was a strong believer in the communist party, and he became the First Secretary from September 7, 1953 to October 14, 1964. Khrushchev was Premier of the Soviet Union from March 27, 1958 to October 14, 1964. When he was 77 years old. He was notorious for his rudeness of interrupting speeches and removing his shoe to bang it on the podium during debates at the United Nations.
John F. Kennedy (1917-1963)
John F. Kennedy was the 35th President of the United States. He was in office from January 20, 1961 until November 22, 1963. Kennedy was the president during the Bay of Pigs, Cuban Missile Crisis, the building of the Berlin Wall, the Vietnam war and the American Civil rights movement. On November 22end ,1963 Kennedy was in Dallas, Texas and was assassinated.
Ronald Reagan(1911-2004)
Ronald Reagan became the 40th president of the United States on January 20, 1981 and left office on January 20, 1989. He was the governor of California from 1967 to 1975. Regan served two terms also partly during the cold war. He ordered a massive military buildup while racing against the Soviet Union. He later spoke with Mikhail Gorbachev and they shrunk the US and Russ

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.
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.

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.
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.

Remembering John Glenn
1.
2. On December 8, 2016, John
Glenn passed away. During
his life, he was a decorated
fighter pilot, a United States
Senator, and the first
American to orbit the earth.
3. Born and raised in Ohio, Glenn
served as a fighter pilot during
World War Two and the Korean
War, earning six Distinguished
Flying Crosses and other
commendations for his service.
In 1957, he performed the first
the first transcontinental flight
at supersonic speed, traveling
from California to New York in
just over three hours.
4. On the morning of February 20, 1962, Glenn was launched into space and became the first American to
orbit the earth. He orbited the planet three times, spending a total of nearly five hours in space, before he
returned to the earth's surface.
Glenn was hailed as a national hero from the moment he stepped out of his module and served as an
inspiration to Americans throughout the remainder of the Space Age and even today!
5. After his orbit, Glenn entered
public service: In 1974, he was
elected to the U.S. Senate as a
representative from his native
Ohio. He remained in office for
25 years, where he was a
respected legislator by officials
of all parties. In 1983, in fact, he
unsuccessfully sought the
Democratic nomination for
President of the United States.
While serving in the Senate, at
the age of 77, Glenn convinced
NASA to send him into space in
order to study the effects of
space travel on the elderly. He
went up for nine days in 1998,
making him the oldest person
to ever go to space!
