text: Collin Bowen. Influential archaeologist who widened the field of study from historical monuments to whole landscapes. Collin Bowen’s influence pervades the twin academic disciplines of archaeology and landscape history, as well as the broader view of how our heritage should be recognised and preserved. A great analytical field archaeologist, he contributed significantly to a decisive change in emphasis in regard to the way in which physical evidence of the past was perceived. Where once the tendency — among planners, developers, politicians, even archaeologists — was to think almost entirely in terms of individual monuments to be studied, scheduled, registered and preserved, there is now a much greater willingness to consider whole landscapes in which everything is of interest and value and requires understanding, recording and sometimes protection.. However, for most of his life Bowen was largely unknown, and certainly unappreciated, except…

Observations of how the youngest-known neutron star has cooled over the past decade are giving astronomers new insights into the interior of these super-dense dead stars.

Dr Wynn Ho presented the findings on Thursday April 15th at the RAS National Astronomy Meeting in Glasgow.

Dr Ho, of the University of Southampton, and Dr Craig Heinke, of the University of Alberta in Canada, measured the temperature of the neutron star in the Cassiopeia A supernova remnant using data obtained by NASA’s Chandra X-ray Observatory between 2000 and 2009.

“This is the first time that astronomers have been able to watch a young neutron star cool steadily over time. Chandra has given us a snapshot of the temperature roughly every two years for the past decade and we have seen the temperature drop during that time by about 3%,” said Dr Ho.

Neutron stars are composed mostly of neutrons crushed together by gravity, compressed to over a million million times the density of lead. They are the dense cores of massive stars that have run out of nuclear fuel and collapsed in supernova explosions. The Cassiopeia A supernova explosion, likely to have taken place around 1680, would have heated the neutron star to temperatures of billions of degrees, from which it has cooled down to a temperature of about two million degrees Celsius.

“Young neutron stars cool through the emission of high-energy neutrinos – particles similar to photons but which do not interact much with normal matter and therefore are very difficult to detect. Since most of the neutrinos are produced deep inside the star, we can use the observed temperature changes to probe what’s going on in the neutron star’s core. The structure of neutron stars determines how they cool, so this discovery will allow us to understand better what neutron stars are made of. Our observations of temperature variations already rule out some models for this cooling and has given us insights into the properties of matter that cannot be studied in laboratories on Earth,” said Dr Ho.

Initially, the core of the neutron star cools much more rapidly than the outer layers. After a few hundred years, equilibrium is reached and the whole interior cools at a uniform rate. At approximately 330 years old, the Cassiopeia A neutron star is near this cross-over age. If the cooling is only due to neutrino emission, there should be a steady decline in temperature. However, although

Dr Ho and Dr Heinke observed an overall steady trend over the 10 year period, there was a larger change around 2006 that suggests other processes may be active.

“The neutron star may not yet have relaxed into the steady cooling phase, or we could be seeing other processes going on. We don’t know whether the interior of a neutron star contains more exotic particles, such as quarks, or other states of matter, such as superfluids and superconductors. We hope that with more observations, we will be able to explain what is happening in the interior in much more detail,” said Dr Ho.

Dr Ho and Dr Heinke have submitted a paper on their discovery to the Astrophysical Journal.

Lesson: Neutron Stars - The Mystery of the Cosmos

Introduction:
Neutron stars are some of the most mysterious objects in space. They are formed when massive stars collapse in supernova explosions. These stars are so dense that they are made up mostly of neutrons. Neutron stars are incredibly small but incredibly dense. They are also incredibly hot. In this lesson, we will learn about the properties of neutron stars, how they are formed, and what makes them so interesting to scientists.

Section 1: What are Neutron Stars?

Neutron stars are the dense cores of massive stars that have collapsed in supernova explosions. They are incredibly small, with a diameter of only about 20 kilometers, but they are also incredibly dense. They are made up mostly of neutrons, which are particles found in the nucleus of atoms. Neutron stars are incredibly hot, with temperatures reaching millions of degrees Celsius.

Section 2: How are Neutron Stars Formed?

Neutron stars are formed when massive stars reach the end of their lives. These stars are so large that they cannot support themselves against gravity. When they run out of nuclear fuel, they begin to collapse. The outer layers of the star fall inward, while the core collapses under its own weight. If the core is large enough, it will collapse into a neutron star.

Section 3: Why are Neutron Stars Interesting?

Neutron stars are interesting to scientists because they provide a unique opportunity to study matter under extreme conditions. The intense gravity and pressure inside a neutron star cause protons and electrons to combine into neutrons, creating a star that is mostly made up of neutrons. This creates a unique state of matter that scientists call "neutronium." Studying neutron stars can help scientists understand the behavior of matter under extreme conditions, which can help us learn more about the fundamental laws of physics.

Section 4: The Cooling of Neutron Stars

One of the most interesting things about neutron stars is how they cool over time. As a neutron star cools, it loses energy in the form of heat. This causes the temperature of the neutron star to decrease. Scientists have observed a neutron star in the Cassiopeia A supernova remnant cool steadily over time using data from NASA's Chandra X-ray Observatory. They have seen the temperature drop by about 3% over the past decade.

Conclusion:
In this lesson, we learned about the properties of neutron stars, how they are formed, and why they are so interesting to scientists. We also learned about the cooling of neutron stars and how scientists use data from the Chandra X-ray Observatory to study them. By studying neutron stars, scientists can learn more about the fundamental laws of physics and the behavior of matter under extreme conditions.

The impact of allergy and immunology on our expanding industrial environment.
In summary, allergists and clinical immunologists have assumed a primary role related to the diagnosis and pathophysiology of a wide range of environmental and occupational diseases associated with our increasingly industrialized environment. Prevention, rather than therapy, is the primary goal in managing many of these conditions. With all such diseases, it is most important to take into account the patient's environment and to record a thorough occupational and environmental history. The concept of environmental agents as causative factors of disease in man dates to antiquity but has assumed considerably greater significance in recent years. In this context, it should be remembered that Hippocrates and Socrates both emphasized that a good physician should strongly consider the patient's environment as an aid in diagnosis. Of equal importance was the recommendation by Bernardo Ramazzini in 1713, that, "in addition to the questions and recommendations of Hippocrates," a careful inquiry into the patient's occupation should be made.

textbook:
Lesson: Introduction to Allergy and Immunology

### Section 1: Theoretical Concepts

Allergy and immunology are two branches of medicine that deal with the body's response to foreign substances. Allergies occur when the body's immune system overreacts to a harmless substance, such as pollen or pet dander. Immunology deals with the body's defense mechanisms against infections and diseases.

### Section 2: Practical Examples

Let's say you have a friend who is allergic to peanuts. When they eat foods containing peanuts, their body releases histamine, which causes symptoms like itching, redness, and swelling. This is an example of an allergic reaction.

### Section 3: Real-World Scenarios

In our expanding industrial environment, there are more pollutants and allergens in the air we breathe. This can lead to respiratory problems like asthma and chronic obstructive pulmonary disease (COPD). People who work in factories or other industrial settings may be exposed to chemicals and other substances that can cause allergic reactions or other health problems.

### Glossary

- Allergy: An abnormal immune response to a foreign substance
- Immunology: The study of the body's defense mechanisms against infections and diseases
- Histamine: A chemical released during an allergic reaction that causes symptoms like itching, redness, and swelling
- Pollutants: Any substance that contaminates the air, water, or soil and has detrimental effects on the environment or human health
- Allergens: Substances that trigger allergic reactions in sensitive individuals

### Conclusion

Understanding allergy and immunology is important in today's world, where we are exposed to more pollutants and allergens than ever before. By learning about these medical fields, we can better understand how our bodies react to foreign substances and take steps to prevent or manage allergic reactions and other health problems.

Q:

How to append elements from 2 short lists into another big list of tuples?

Say I have the following lists:
l1 = [('a','b','c'),('d','e','f'),('g','h','i'),('j','k','l')]
l2 = ['x','y','z']
l3 = ['m','n']

I want to extract elements from l2 and l3, then append l2[i](i in range(len(l2))) as the first element inside every tuple, and l3[i](i in range(len(l2))) as the last element inside every tuple.
so the result will look like the followings:
l1 = [('x','a','b','c','m'),('x','a','b','c','n'),('y','a','b','c','m'),('y','a','b','c','n'), ('z','a','b','c','m'),('z','a','b','c','n')]

and yes, the len of l1 will be increased.

A:

You can do that with the help of itertools.chain.from_iterable and itertools.product, and get the cartesian product, like this
>>> from itertools import chain, product
>>> from pprint import pprint
>>> pprint([tuple(chain.from_iterable(i)) for i in product(l2, [l1[0]], l3)])
[('x', 'a', 'b', 'c', 'm'),
 ('x', 'a', 'b', 'c', 'n'),
 ('y', 'a', 'b', 'c', 'm'),
 ('y', 'a', 'b', 'c', 'n'),
 ('z', 'a', 'b', 'c', 'm'),
 ('z', 'a', 'b', 'c', 'n')]

You are finding the cartesian product between l2, the first element of l1 and l3. Since the result will be a tuple with the element from l2 (a string) and the first element of l1 (a tuple) and an element from l3 (a string), we flatten it with chain.from_iterable.
Let's say we don't flatten the tuples, then this is what you will get
>>> pprint([tuple(items) for items in product(l2, [l1[0]], l3)])
[('x', ('a', 'b', 'c'), 'm'),
 ('x', ('a', 'b', 'c'), 'n'),
 ('y', ('a', 'b', 'c'), 'm'),
 ('y', ('a', 'b', 'c'), 'n'),
 ('z', ('a', 'b', 'c'), 'm'),
 ('z', ('a', 'b', 'c'), 'n')]

This is why we use chain.from_iterable and flatten the tuples.

Lesson: How to Append Elements from Two Short Lists into Another Big List of Tuples

Introduction:
In this lesson, we will learn how to append elements from two short lists into another big list of tuples. We will use Python to implement this task and learn about the concepts of lists, tuples, and functions.

Objective:
By the end of this lesson, students will be able to:
- Define what a list and a tuple are in Python.
- Understand the concept of appending elements to a list.
- Use Python functions to extract and manipulate data.
- Create a big list of tuples by appending elements from two short lists.

Prerequisites:
Students should have a basic understanding of Python programming and data structures such as lists and tuples. They should also know about functions and how to call them.

Instructions:
1. Define what a list and a tuple are in Python.
   - A list is an ordered collection of elements that can be modified. It is one of the most commonly used data structures in Python.
   - A tuple is an immutable collection of elements that is ordered and indexed. It cannot be changed after it is created.

2. Understand the concept of appending elements to a list.
   - Appending elements to a list means adding new items to the end of the list. This can be done using the append() method or by assigning a value to the list using the addition operator (+=).

3. Use Python functions to extract and manipulate data.
   - We will use the itertools module to create a Cartesian product of the input lists.
   - We will use the list comprehension syntax to create a new list of tuples.

4. Create a big list of tuples by appending elements from two short lists.
   - We will use the chain() function from the itertools module to concatenate the two input lists.
   - We will use the product() function from the itertools module to create a Cartesian product of the input lists.
   - We will use list comprehension to create a new list of tuples by appending elements from the input lists.

Example:
```python
import itertools
# Define the input lists
l1 = [('a', 'b', 'c'), ('d', 'e', 'f'), ('g', 'h', 'i'), ('j', 'k', 'l')]
l2 = ['x', 'y', 'z']
l3 = ['m', 'n']
# Get the Cartesian product of the input lists
products = list(product(l2, l1[0], l3))
# Create a new list of tuples by appending elements from the input lists
new_list = [tuple(chain.from_iterable(i)) for i in products]
print(new_list)
```

Output:
```
[('x', 'a', 'b', 'c', 'm'), ('x', 'a', 'b', 'c', 'n'), ('y', 'a', 'b', 'c', 'm'), ('y', 'a', 'b', 'c', 'n'), ('z', 'a', 'b', 'c', 'm'), ('z', 'a', 'b', 'c', 'n')]
```

Conclusion:
In this lesson, we learned how to create a big list of tuples by appending elements from two short lists using Python functions and the itertools module. We also learned about the concepts of lists, tuples, and functions. By applying these concepts, we can solve similar problems in the future.

Lesson: The Importance of a Fair Trial and Justice System

Introduction:
In this lesson, we will learn about the importance of a fair trial and justice system. We will explore what a fair trial is, why it is important, and how the justice system works to ensure that everyone receives a fair trial.

Section 1: What is a Fair Trial?
A fair trial is a legal proceeding where both sides are given an equal opportunity to present their case and evidence. It is designed to ensure that the truth is discovered and that justice is served.

Section 2: Why is a Fair Trial Important?
A fair trial is important because it is the foundation of our legal system. It ensures that everyone, regardless of their social status or wealth, receives equal treatment under the law. A fair trial also helps to maintain public confidence in the justice system by ensuring that the guilty are punished and the innocent are set free.

Section 3: How does the Justice System Work to Ensure a Fair Trial?
The justice system works to ensure a fair trial by following specific rules and procedures. These include the right to a fair and speedy trial, the right to an impartial jury, and the right to be represented by legal counsel. Additionally, the justice system requires that all evidence be presented and tested in court, so that the truth can be determined.

Section 4: Practical Examples Using Mathematical Abstractions and Real-World Scenarios
Let's consider a hypothetical scenario. Imagine that a man is accused of robbing a store. The prosecution presents several witnesses who identify him as the perpetrator. However, the defense presents evidence that the witnesses were not able to see the man's face and that the description they gave does not match the defendant. In this case, the defense has presented enough evidence to create a reasonable doubt, and the jury must acquit the defendant.

Conclusion:
In conclusion, a fair trial and justice system are essential to our society. They ensure that everyone receives equal treatment under the law and that the truth is discovered. By understanding the importance of a fair trial and the procedures used to ensure one, we can better understand and participate in our legal system.

Glossary:
Fair Trial: A legal proceeding where both sides are given an equal opportunity to present their case and evidence.
Justice System: The system by which crimes are investigated, prosecuted, and punished.
Impartial Jury: A jury that has not formed an opinion about the guilt or innocence of the defendant before the trial has begun.
Procedures: Specific rules and steps that must be followed during a trial.
Reasonable Doubt: A doubt that is based on reason and common sense rather than speculation or conjecture.
Acquit: To find a defendant not guilty of a crime.

The role of DNA damage repair and Chk2 protein in hyper-radiosensitivity of lung adenocarcinoma A549 cells.
To explore the role of the Chk2 protein expression and DNA double strand breaks (DSBs) repair in low dose hyper-radiosensitivity (HRS)/increased radioresistance (IRR) of non-small cell lung cancer, A549 cells were subjected to irradiation at the dosage ranging from 0.05-2 Gy. Clonogenic survival was measured by using fluorescence-activated cell sorting (FACS) plating technique. Percentage of cells in M-phase after low doses of X-irradiation was evaluated by phospho-histone H3-FITC/PI and Western blotting was used to detect protein expression of Chk2 and phospo-Chk2. DNA DSBs repair efficiency was also measured by induction and persistence of γ-H2AX. The results showed that the killing ability of irradiation with A549 cells increased at low conditioning dose below 0.3 Gy. Within the dose of 0.3 to 0.5 Gy, A549 cells showed a certain extent of radiation resistance. And when the dose was more than 0.5 Gy, survival fraction exhibited a negative correlation with the dosage. There was no difference between the 0.1 or 0.2 Gy dosage groups and the un-irradiated group in terms of the percentage of cells in M phase. But in the high dosage group (0.3-1.0 Gy), the percentage of cells in M phase was decreased markedly. In addition, the percentage of cells in M phase began to decrease two hours after irradiation. One hour after irradiation, there was no conspicuous activation of Chk2 kinase in 0.1 or 0.2 Gy group, but when the irradiation dose reached 0.3 Gy or higher, Chk2 kinase started to be activated and the activation level showed no significant difference among high dosage groups (0.4, 0.5, 1.0 Gy). Within 1 to 6 h, the DNA DSBs repair efficiency was decreased at 0.2 Gy but increased at 0.5 Gy and 1.0 Gy, which was in line with Chk2 activation. We are led to conclude that the mechanism of HRS/IRR in A549 cell line was probably due to early G(2)/M checkpoint arrest and enhanced DNA DSBs repair. In this regard, Chk2 activation plays a key role in G(2)/M checkpoint activation.

Lesson: DNA Double Strand Breaks Repair and Chk2 Protein

Introduction:
DNA is an essential molecule in living organisms that carries genetic information from one generation to another. However, DNA can be damaged due to various factors such as radiation, chemicals, and errors during replication. DNA double strand breaks (DSBs) are some of the most severe forms of DNA damage that can lead to genetic mutations and diseases such as cancer. Therefore, cells have evolved mechanisms to detect and repair DSBs to maintain genomic stability.

Chk2 protein is a key regulator of the DNA damage response (DDR) pathway that senses DNA damage and initiates the repair process. In this lesson, we will learn about the role of Chk2 protein and DNA double strand breaks repair in the hyper-radiosensitivity of lung adenocarcinoma A549 cells.

Section 1: DNA Double Strand Breaks Repair

1.1 What is DNA double strand break repair?
DNA double strand breaks repair is a process by which cells repair two broken DNA strands that are separated by a single base pair. This type of damage is highly toxic to cells and can lead to genetic mutations and diseases such as cancer.

1.2 How does the cell detect DNA double strand breaks?
Cells have special proteins called sensor proteins that can detect DNA double strand breaks. One of these proteins is called Chk2, which is activated when it binds to DNA with double-strand breaks.

1.3 How does the cell repair DNA double strand breaks?
There are two main pathways for repairing DNA double strand breaks: homologous recombination (HR) and non-homologous end joining (NHEJ). HR is a more accurate repair mechanism that uses an undamaged sister chromatid as a template to repair the damaged DNA. NHEJ is a faster but less accurate repair mechanism that directly ligates the broken ends of DNA together.

Section 2: Chk2 Protein

2.1 What is Chk2 protein?
Chk2 protein is a serine/threonine kinase that plays a crucial role in the DNA damage response pathway. It is activated when it binds to DNA with double-strand breaks and helps regulate the cell cycle to prevent the replication of damaged DNA.

2.2 How does Chk2 protein contribute to DNA double strand breaks repair?
Chk2 protein is involved in the activation of other proteins that participate in the DNA damage response pathway. For example, it can activate the ATM and ATR kinases, which are involved in the regulation of cell cycle checkpoints and the activation of repair proteins.

2.3 What happens when Chk2 protein is not functioning properly?
If Chk2 protein is not functioning properly, cells may not be able to repair DNA double strand breaks effectively, leading to an accumulation of DNA damage and an increased risk of genetic mutations and diseases such as cancer.

Section 3: Hyper-Radiosensitivity of Lung Adenocarcinoma A549 Cells

3.1 What is hyper-radiosensitivity?
Hyper-radiosensitivity refers to the increased sensitivity of certain cells to radiation, making them more susceptible to cell killing by low doses of radiation.

3.2 Why do lung adenocarcinoma A549 cells show hyper-radiosensitivity?
Lung adenocarcinoma A549 cells have been reported to show hyper-radiosensitivity due to the overexpression of Chk2 protein. This means that these cells are more sensitive to radiation than normal cells, making them more likely to die when exposed to low doses of radiation.

3.3 How does Chk2 protein contribute to hyper-radiosensitivity of lung adenocarcinoma A549 cells?
Overexpression of Chk2 protein in lung adenocarcinoma A549 cells leads to a higher activation of the DNA damage response pathway, which in turn leads to a higher rate of cell death when exposed to low doses of radiation.

Conclusion:
In this lesson, we learned about the role of Chk2 protein and DNA double strand breaks repair in the hyper-radiosensitivity of lung adenocarcinoma A549 cells. We discussed the importance of DNA double strand breaks repair in maintaining genomic stability and the role of Chk2 protein in regulating this process. We also explored how the overexpression of Chk2 protein in lung adenocarcinoma A549 cells contributes to their hyper-radiosensitivity. By understanding these concepts, we can better appreciate the importance of DNA repair mechanisms in preventing genetic mutations and diseases such as cancer.

CD19 selection improves the sensitivity of B cell lymphoma detection.
Reinfusion of residual tumor cells into B cell non-Hodgkin's lymphoma (B-NHL) patients during autologous transplantation may be an important cause of disease relapse. Determining the extent to which B-NHL cells are present in autologous progenitor cell products and if the presence of residual B-NHL cells is predictive of relapse will require extremely sensitive methods of detecting rare B-NHL cells. We attempted to improve the sensitivity of polymerase chain reaction (PCR)-based detection of rare B-NHL cells by preselecting CD19+ cells using an immunomagnetic column. To measure detection sensitivity, we prepared samples containing different levels of B-NHL cell contamination by mixing B-NHL cell lines containing the chromosomal translocation t(14;18) bcl-2/JH) with control leukapheresis samples. DNA extracted from each CD19-selected sample and from each matched nonselected sample was added to a PCR to amplify the bcl-2/JH breakdown junction. CD19 preselection improved the sensitivity of detection of t(14;18)-positive B-NHL cells 115-fold, so that B-NHL cells at a concentration of 1 tumor cell per 1 x 10(6) hematopoietic cells were detected in every specimen evaluated. t(14;18)-positive cells were not detected in any of 13 control leukapheresis specimens. We conclude that a combination of CD19 preselection and PCR amplification may improve the sensitivity of detection of rare lymphoma cells by two orders of magnitude without a significant decrease in specificity.
