The student thanks their teacher for the opportunity to do a project on creating cremation diamonds from ashes. Cremation diamonds are real diamonds created from the cremated remains of a loved one through a process of converting the carbon in the ashes to pure carbon, creating a core, and placing it under high temperature and pressure to form a diamond. The process involves five steps - preparing the ashes into a powder, converting it to pure carbon, making a carbon core, placing the core under heat and pressure to form a diamond, and finally cutting and polishing the rough diamond. Cremation diamonds provide a meaningful way to memorialize and keep loved ones close.

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.

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.
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.

4. Carbon is chemical element with symbol C, and atomic
number 6, a non-metal which has two main forms
(diamond and graphite) and which also occurs in impure
form in charcoal, soot, and coal.
The picture showing different forms of carbon in nature.
5. Carbon is capable of forming many allotropes due to its
valency. Well-known forms of carbon include diamond and
graphite. In recent decades many more allotropes and
forms of carbon have been discovered and researched
including ball shapes such as buckminsterfullerene and
sheets such as graphene. Other unusual forms of carbon
exist at very high temperature or extreme pressures.
6. Major Allotropes of carbon:
(a) Diamond,
(b) Graphite,
(c) Lonsdaleite,
(d) C60 (Buckminsterfullerene).
7. In mineralogy, diamond is a metastable allotrope of
carbon, where the carbon atoms are arranged in a
variation of the face - centered cubic crystal structure
called a diamond lattice.
Diamond is renowned as a material with superlative
physical qualities, most of which originate from the
strong covalent bonding between its atoms. In
particular, diamond has the highest hardness and
thermal conductivity of any bulk material. Those
properties determine the major industrial application of
diamond in cutting and polishing tools and the scientific
applications in diamond knives and diamond anvil
cells.
8. STRUCTURE –
In diamond each carbon atom is linked to other four carbon
atoms(by covalent bonding). The structure extends in space and
produces a rigid 3-D network of carbon atoms. It is very difficult to
break extended covalent bonds therefore diamond is a hardest
substance on Earth.
USES –
Because diamonds are so hard and durable, they are ideal for
grinding, cutting, drilling, and polishing. When used as an abrasive,
very small pieces of diamond are embedded into grinding wheels,
