text: Luckily, gene drives can be reverted. One would need to release another gene drive that disables the first one. (this is just a test answer, dont know if this is correct). Essentially yes - this is why all laboratories building gene drive systems that are candidates for eventual release should always build an "immunizing reversal drive" at the same time.. An "immunizing reversal drive" can be used to overwrite any unwanted changes caused by an earlier gene drive. Releasing one such drive should be able to reverse the problematic trait in essentially all cases; releasing two in succession could restore the exact original sequence plus the CRISPR genes required for gene drive. Immunizing reversal drives can perfectly undo changes made to population of organisms, those changes might have had effects on other species and consequently altered the ecosystem in ways that can't be undone. Like so many things involving gene drives, it will depend on the species and the nature of the original change.

Lesson Title: Gene Drives and Their Reversal

Introduction:
Gene drives are a powerful tool used by scientists to change the genetic makeup of living organisms. They work by spreading a specific gene through a population, effectively altering the traits of future generations. However, what happens if something goes wrong with a gene drive? In this lesson, we will learn about the concept of gene drives, their potential risks, and how they can be reversed.

Section 1: What are Gene Drives?
A gene drive is a genetic engineering technique that can change the genetic makeup of a population of organisms. It works by creating a genetic element that is inserted into an organism's DNA. This genetic element contains instructions for producing a specific protein, which is then passed on to the next generation. Over time, the frequency of this gene increases until it becomes the dominant gene in the population.

Section 2: Risks of Gene Drives
While gene drives have great potential for good, they also come with risks. For example, if a gene drive is released into the wild without proper testing, it could have unintended consequences. This could lead to the extinction of certain species or alter the ecosystem in ways that cannot be undone.

Section 3: Reversing Gene Drives
Essentially, yes - this is why all laboratories building gene drive systems that are candidates for eventual release should always build an "immunizing reversal drive" at the same time. An "immunizing reversal drive" can be used to overwrite any unwanted changes caused by an earlier gene drive. Releasing one such drive should be able to reverse the problematic trait in essentially all cases; releasing two in succession could restore the exact original sequence plus the CRISPR genes required for gene drive.

Immunizing reversal drives can perfectly undo changes made to population of organisms, those changes might have had effects on other species and consequently altered the ecosystem in ways that can't be undone. Like so many things involving gene drives, it will depend on the species and the nature of the original change.

Conclusion:
In this lesson, we learned about gene drives and their potential risks. We also learned about the concept of reversing gene drives using immunizing reversal drives. This knowledge is important for scientists who are working with gene drives and for policymakers who are considering the use of this technology. By understanding the risks and potential solutions, we can ensure that gene drives are used responsibly and safely.

I've noticed the last couple of years that here in my locale it doesn't really exist.
The hawthorn is just finishing & the sycamore not long over & already a reasonable amount of white clover & bramble in evidence.
What is it like with your bees?

I think if you have gardens or wild areas round you its fine. Its the large fields under cultivation that are problems I think. We have been surrounded on 2 sides (since we moved here) with acres of miscanthus, so we only have cropping fields on 2 sides. This year its wheat, last year spuds, so not particularly helpful. I really a lot on tree pollen & nectar, so small fields with hedges is really important.
I cut & laid our perimeter hedge this winter, but its been blooming again with sloe and Ive planted a lot of rosemary & daisy type plants. I could never sustain more than 2 colonies here, mainly because of lack of forage.

Interesting you are both in Cornwall, I am in Surrey and my bees are in my suburban back garden. I agree more with Tav, the gardens are flowering well, hedges are just finishing, Clover and brambles are flourishing and lots of trees nearby.

Think it will depend on where you are. The best places for bees these days is in town because of all the garden flowers. The OSR is over by June and they haven't grown any spring rape, which used to give us a good crop, for years, but we do get wild raspberry and then bramble flowers for our bees in the woods.

the best place for a lot of "common"wildlife is urban gardens,they provide year round food(inc supplements from bird tables,bin bags,kebab droppings etc, etc)and many folk have reduced or stopped using pesticides,there are a variety of niches to live in .

an industrial agricultural landscape is built to favour a monoculture of a crop and wildlife is a pest or bycatch of pest control

There's no June gap here. The hedges around the farm have been planted with dog roses which are covered in flowers at the moment, brambles are out and there is so much honeysuckle along the lanes that the car smelt sweetly of it as I drove along. The fields are full of flowers and then there is gorse of course.

I was told by my beekeeping instructor that honey bees cannot sup from honeysuckle, as their tongues are not long enough to reach the nectar.

Gorse is mostly good for pollen.

EB Wedmore a Manual for Bee-Keeping, has tables in it of what plants are good for nectar, which are minor but useful and which is pollen only. Very useful.

This is what I was led to believe as well.
Wedmores book is a useful reference for many things.
Honey bees will take advantage of some of the deeper flowers by following one of the small bumble species that eats a hole at the base of the flower to reach the nectar.
I've seen my bees do this on runner bean flowers.
Sorry Dpack replied to muttons post before I read yours.

It is quite common for bumble bees to chew a hole in bean flowers to get at the nectar. The honey bees can then access the flowers. It also depends upon rain fall. Buddleia is useful for bees if it has been raining a lot as the tube fills with nectar, but goes down in dryer weather so only moths and butterflies can access it.

Lesson: Introduction to Pollination

Pollination is the process of transferring pollen from the male reproductive organs of a flower to the female reproductive organs. This process is essential for the fertilization of flowers and the production of seeds and fruits. In this lesson, we will learn about the different types of pollination, the importance of pollinators, and the role of pollination in the ecosystem.

**Section 1: Types of Pollination**

There are three main types of pollination: self-pollination, cross-pollination, and animal-assisted pollination. Self-pollination occurs when pollen is transferred from the male parts of a flower to the female parts of the same flower. Cross-pollination occurs when pollen is transferred from one flower to another flower of a different plant. Animal-assisted pollination occurs when pollen is transferred from one flower to another by animals such as bees, butterflies, and birds.

**Section 2: Pollinators**

Pollinators are animals that help transfer pollen from one flower to another. Some common pollinators include bees, butterflies, and hummingbirds. These animals play a crucial role in the ecosystem by helping plants reproduce and spread their seeds. Without pollinators, many plants would not be able to survive.

**Section 3: Role of Pollination in the Ecosystem**

Pollination plays an essential role in the ecosystem by helping plants reproduce and spread their seeds. This process allows plants to produce new generations and contributes to the overall health and stability of ecosystems. Additionally, pollination helps maintain the balance between different species in an ecosystem by ensuring that each plant has the opportunity to reproduce and thrive.

**Conclusion**

In conclusion, pollination is a vital process that supports the growth and reproduction of plants in the ecosystem. Understanding the different types of pollination and the role of pollinators can help us appreciate the importance of these processes and take steps to protect them. By learning about pollination, we can better understand the delicate balance of nature and the interconnectedness of all living things.

Ivan’s Childhood is a double gateway into filmic pastures of unimaginable richness. It is the most accessible introduction to the work of Russian film-maker Andrei Tarkovsky, whose sprawling 70s masterpieces Mirror and Stalker it prefigures in its audacious imagery and elliptical narrative technique. There’s his catalogue of images: moving water reflecting the sky, silver birch forests, cast-iron bells, religious icons, horses, apples, mud, war; the fluid, serpentine camera movements of impressive duration and sensuality; and the prodigally poetic method of storytelling, with unsignposted dream sequences and flashbacks. It stands among the greatest directorial debuts ever made.

Ivan is 12, parentless, alone in the war zone along the river Dnieper, drifting between partisan bands and regular Red Army units, offering himself as a scout. He is seeking vengeance against the Nazis who killed his family. But he is still a child and Tarkovsky never loses sight of the disjunction between the boy and the world: it is here that he finds his poetry, in childlike wonder set against horror and deprivation.

Ivan’s Childhood is also a door to one of the most fascinating backwaters of world cinema: Soviet cinema during the late 50s to mid-60s. Soviet film-makers – in Moscow and in the satellite states – seized a new kind of formal freedom. Thus Russia was suddenly making realist war movies such as The Cranes Are Flying and Ballad Of A Soldier, and not-so-realist ones like Ivan and Larisa Shepitko’s 1966 debut Wings.

After Ivan’s Childhood, the Georgian-Armenian director Sergei Parajanov was inspired to break with officially sanctioned Soviet realism and make his revolutionary tone poem Shadows Of Forgotten Ancestors. In Poland, Andrzej Wajda and his protege Roman Polanski forged new paths, both dissident and surrealistic, while in Hungary, Miklós Jancsó’s My Way Home and The Round-Up embraced all things fluid and painterly. The Czech film-makers had such a good time of it that the Russians marched in and crushed them along with Dubček.

Here ended The Thaw. After the ascent of Brezhnev, all these film-makers would suffer severe problems with authorities over their next movies: Tarkovsky on Andrei Rublev, Parajanov for The Colour Of Pomegranates, Shepitko with You And I, and Wajda with pretty much everything. Polanski’s second feature was made in exile, where most of the Czechs joined him after 1968, and Tarkovsky 10 years later. But for a short, ecstatic decade, Soviet film-making set the pace for the rest of the world. Avail yourself of it.

A year and a half ago it became known that the company Royal Philips has signed an agreement with a Chinese consortium, GO Scale Capital regarding the sale of 80.1% of units Lumileds, which produces led components lighting (including car). Then it was reported that the value of the deal is 2.8 billion dollars.. It turned out that the deal wasn’t meant to be. The fact that their objections advanced by the Committee on foreign investment in USA (Committee on Foreign Investment in the United States; CFIUS), in fact, blocking the deal.. Because of this, Philips had to significantly reduce the cost of sale and seek a new buyer. He was found in the US, so now CFIUS is unlikely to find reasons to ban sales. The purchaser is a private investment company Apollo Global Management. The new transaction amount — $ 1.5 billion. It must be completed in the first half of 2017.. Philips. Comment

Lesson: Introduction to Economic Principles

## Chapter 1: Supply and Demand

### Section 1: Theory

In this chapter, we will learn about the basic economic principle of supply and demand. This principle states that the price of a good or service is determined by the relationship between the quantity that producers are willing to sell and the quantity that consumers are willing to buy at a given price.

### Section 2: Practice

1. What is the law of supply and demand?
- The law of supply and demand is an economic principle that states that the price of a good or service is determined by the relationship between the quantity that producers are willing to sell and the quantity that consumers are willing to buy at a given price.

2. How does the law of supply and demand work?
- The law of supply and demand works by balancing the interests of producers and consumers. When the price of a good or service is high, producers are willing to supply more of it because they can make more profit. At the same time, consumers are willing to buy less of it because it is more expensive. As the price falls, producers are willing to supply less of the good or service, while consumers become more willing to buy more. Eventually, the price reaches a point where both producers and consumers are satisfied, and the market reaches equilibrium.

3. Why does the law of supply and demand matter?
- The law of supply and demand matters because it helps us understand how markets work. It shows us that prices are not set by governments or other external forces, but rather by the interactions of millions of individuals making billions of decisions every day. By understanding how supply and demand work together, we can make better choices as consumers and businesses.

### Section 3: Application

Let's apply the law of supply and demand to the case of Royal Philips trying to resell its Lumileds unit.

1. What is happening in the market for LED lighting components?
- The market for LED lighting components is experiencing growth due to increasing demand for energy-efficient lighting solutions.

2. How is this affecting the price of LED lighting components?
- As demand for LED lighting components increases, the price is also increasing.

3. Why did Royal Philips initially fail to sell Lumileds?
- Royal Philips initially failed to sell Lumileds because the deal was blocked by the Committee on Foreign Investment in the United States (CFIUS) due to national security concerns.

4. Why did Royal Philips eventually decide to sell Lumileds for $1.5 billion?
- Royal Philips decided to sell Lumileds for $1.5 billion because it found a new buyer in a US-based private investment company, Apollo Global Management. Since the new buyer is based in the US, there are unlikely to be any objections from CFIUS.

5. How does this example illustrate the law of supply and demand?
- This example illustrates the law of supply and demand because the price of LED lighting components has increased due to growing demand. Royal Philips initially failed to sell Lumileds because the deal was blocked by CFIUS, which affected the supply and demand dynamics. However, when Royal Philips found a new buyer in Apollo Global Management, the supply and demand dynamics changed again, leading to a lower selling price.

## Glossary

- Law of supply and demand: An economic principle that explains how the price of a good or service is determined by the relationship between the quantity that producers are willing to sell and the quantity that consumers are willing to buy at a given price.

Level: Primary through High School
Prerequisites: Basic knowledge of taxation and accounting principles.
Introduction:
GST or Goods and Services Tax is a comprehensive indirect tax levied on the supply of goods and services in India. It was introduced to simplify the existing indirect tax structure and eliminate multiple taxation. GST Section 78 deals with the initiation of recovery proceedings in case of non-payment of tax dues.
Section 78 of GST Act 2017 - Initiation of recovery proceedings
(1) Where any tax, interest or penalty has been determined under this Act and remains unpaid, the proper officer may issue a notice to the person liable to pay the same, calling upon him to show cause within seven days of the issue of the notice why the amount should not be recovered from him and thereafter recovery may, subject to the provisions of sub-section (2), be made by the proper officer in the following manner, namely:–
(a) the proper officer may recover the amount from the said person by one or more of the following modes of recovery, namely:–
(i) by adjustment from any refund due to such person;
(ii) by deduction from any money payable by the Government to such person;
(iii) by deduction from any money payable by the proper officer to such person or by him to the Government;
(b) in case of a company, the proper officer may recover the amount from the directors of the company who are personally responsible for the company’s default, after giving them a reasonable opportunity of being heard.
(2) No recovery shall be made under sub-section (1) without giving an opportunity to the person liable to pay the tax, interest or penalty to be heard and without serving a notice in writing to him in the manner specified in section 76, and where the notice is served, the service of such notice shall be preceded by the issuance of an order in writing, specific to the tax, interest or penalty, determining the sum payable.
(3) Notwithstanding anything contained in this section, any person entitled to make payment of tax, interest or penalty may make payment to the credit of the Central Government in the prescribed manner and such payment shall be deemed to have been made to the credit of the appropriate Government and the amount so paid shall be adjusted against the tax, interest or penalty payable by him under this Act.
Analysis:
GST Section 78 outlines the procedure for initiating recovery proceedings in case of non-payment of tax dues. The proper officer may issue a notice to the person liable to pay the tax, interest or penalty, calling upon him to show cause why the amount should not be recovered from him. After the show-cause notice is issued, the proper officer may recover the amount by one or more of the following modes of recovery:
1. Adjustment from any refund due to such person
2. Deduction from any money payable by the Government to such person
3. Deduction from any money payable by the proper officer to such person or by him to the Government
If the person liable to pay the tax, interest or penalty fails to pay the amount within the specified time, the proper officer may recover the amount from the directors of the company who are personally responsible for the company's default, after giving them a reasonable opportunity of being heard.
The section also provides that no recovery shall be made under sub-section (1) without giving an opportunity to the person liable to pay the tax, interest or penalty to be heard and without serving a notice in writing to him in the manner specified in section 76.
Conclusion:
GST Section 78 is an important provision that outlines the procedure for initiating recovery proceedings in case of non-payment of tax dues. Businesses and individuals must ensure compliance with this section to avoid penalties and legal action. Understanding the provisions of GST Section 78 can help in effective tax planning and management.

A novel catechol-based universal support for oligonucleotide synthesis.
A novel universal support for deoxyribo- and ribonucleic acid synthesis has been developed. The support, constructed from 1,4-dimethoxycatechol, represents an improvement over existing universal supports because of its ability to cleave and deprotect under mild conditions in standard reagents. Because no nonvolatile additives are required for cleavage and deprotection, the synthesized oligonucleotides do not require purification prior to use in biochemical assays. Using reverse phase HPLC and electrospray mass spectroscopy, it was determined that oligonucleotides synthesized on the universal support (UL1) 3'-dephosphorylate quickly (9 h in 28-30% ammonium hydroxide (NH4OH) at 55 degrees C, 2 h in 28-30% NH4OH at 80 degrees C, or <1 h in ammonium hydroxide/methylamine (1:1) (AMA) at 80 degrees C). Oligonucleotides used as primers for the polymerase chain reaction (PCR) assay were found to perform identically to control primers, demonstrating full biological compatibility. In addition, a method was developed for sintering the universal support directly into a filter plug which can be pressure fit into the synthesis column of a commercial synthesizer. The universal support plugs allow the synthesis of high-quality oligonucleotides at least 120 nucleotides in length, with purity comparable to non-universal commercial supports and approximately 50% lower reagent consumption. The universal support plugs are routinely used to synthesize deoxyribo-, ribo-, 3'-modified, 5'-modified, and thioated oligonucleotides. The flexibility of the universal support and the efficiency of 3'-dephosphorylation are expected to increase the use of universal supports in oligonucleotide synthesis.

Lesson: Introduction to Oligonucleotide Synthesis

### Section 1: Theoretical Concepts

Oligonucleotide synthesis is the process of creating short, single-stranded DNA or RNA molecules called oligonucleotides. These molecules can be used in various applications such as gene cloning, DNA sequencing, and PCR. In this lesson, we will learn about the basics of oligonucleotide synthesis, including the structure of nucleotides, the process of oligonucleotide synthesis, and the importance of using a universal support.

### Section 2: Practical Examples

To understand the importance of using a universal support, let's consider an example. Suppose you are synthesizing a 20-mer oligonucleotide with a 5' phosphate and a 3' amino group. You can use a universal support like 1,4-dimethoxycatechol to synthesize the oligonucleotide. After the synthesis, you need to remove the protecting groups and dephosphorylate the 5' end. With the universal support, you can use mild conditions and standard reagents to cleave and deprotect the oligonucleotide without the need for purification. This saves time and effort compared to other supports that require additional steps and purification.

### Section 3: Self-Debating Discussions

Why is it important to use a universal support for oligonucleotide synthesis?

Argument 1: Universal supports allow for easy cleavage and deprotection of the oligonucleotide, saving time and effort.
Argument 2: Using a universal support reduces the need for purification, making the process more efficient and cost-effective.
Argument 3: Some supports may not be compatible with certain reagents or conditions, which can affect the quality of the final product. A universal support eliminates this issue.

Conclusion: Using a universal support like 1,4-dimethoxycatechol for oligonucleotide synthesis offers several advantages, including easier cleavage and deprotection, reduced purification steps, and compatibility with a wide range of reagents and conditions. By understanding the theoretical concepts and practical examples presented in this lesson, students can apply these skills to synthesize oligonucleotides for various applications.

Lesson: Understanding and Using Technical Specifications

Introduction:
Technical specifications are essential when choosing electronic devices, especially power supplies. In this lesson, we will learn how to read and understand technical specifications for a power supply unit (PSU).

Section 1: Understanding Technical Specifications

Topic 1: Reading Technical Specifications
- Technical specifications provide information about a device's features, capabilities, and limitations.
- They are usually presented in a table or list format, with columns for the specification name, unit of measurement, minimum value, maximum value, and tolerance.
- Manufacturers may use different names for the same specification, so it is essential to know the common names for each parameter.

Topic 2: Important Specifications for Power Supplies
- Output voltage: The voltage at which the power supply provides power to the load.
- Output current: The maximum current the power supply can deliver without damage.
- Efficiency: The percentage of input power converted into output power.
- Power factor: The ratio of real power to apparent power in a load.
- Noise: The electrical noise generated by the power supply, which can interfere with sensitive electronics.

Section 2: Analyzing Technical Specifications

Topic 1: Comparing Power Supplies
- To compare power supplies, look at their output voltage, current, efficiency, and noise specifications.
- Choose a power supply with an output voltage that matches the requirements of the load.
- Higher efficiency and power factor mean lower energy consumption and better performance.
- Lower noise levels are preferable for sensitive electronics.

Topic 2: Calculating Power Requirements
- To calculate the power requirements of a load, multiply the voltage and current values.
- For example, if the load requires 12V at 1A, the power requirement is 12W.
- If the power supply has an efficiency of 80%, it will consume 12W / 0.8 = 15W.

Section 3: Practical Examples

Example 1: Choosing a Power Supply for a Load
- A load requires 5V at 2A.
- We need a power supply with an output voltage of 5V and an output current of at least 2A.
- The efficiency and noise specifications are secondary considerations.

Example 2: Designing a Power Supply
- A designer needs to create a power supply that provides 12V at 5A.
- The required output current is 5A, so the power supply must have an efficiency of at least 5A / 12V = 0.4167W / 12V = 0.0347W or 3.47%.
- The power factor must be at least 0.9 for a load with a power factor of 0.9.

Conclusion:
Understanding and analyzing technical specifications for power supplies is crucial when selecting the right device for a particular application. By considering factors such as output voltage, current, efficiency, power factor, and noise, we can choose the best power supply for our needs. By applying these concepts to practical examples, we can design and select power supplies that meet our requirements and perform optimally.

text: My 4-yr old daughter, Camille, is huge into coloring and drawing. She's just recently discovered that she can now draw lots of things. She's been making sailboats using shapes, tracing bowls and cups, and making all kinds of scenes. She drew this for me the other day. It's our family (including our 6-legged dog Harley down at the bottom) and we're all happy under the beautiful rainbow (exactly how she put it). She said she made it especially for my sewing room. So now I get to look at this great picture everyday. . .I absolutely love it!!!. Her drawing reminds me of two things: how blessed I am and how uncomplicated life should be. To be a kid again, and to think so simply and innocently would be the best. There's no stresses, no money, no sadness, no hunger, no hate whatsoever in her picture. It's love, family, security, and beauty all in one and it's from a 4-yr old's heart.

Lesson: Introduction to Chemistry

## Section 1: Theoretical Concepts

In this section, we will cover the basic concepts of chemistry that are essential for understanding the properties and behavior of matter. We will start with the atomic structure and move on to the concept of elements, compounds, and mixtures.

**Topic 1: Atomic Structure**

The atomic structure refers to the arrangement of protons, neutrons, and electrons in an atom. An atom is the smallest unit of matter that retains its chemical identity. The atomic number of an element represents the number of protons in its nucleus. Elements are classified as metals, nonmetals, or metalloids based on their properties.

**Topic 2: Elements, Compounds, and Mixtures**

An element is a pure substance made up of only one type of atom. A compound is a substance made up of two or more different elements chemically bonded together. A mixture is a combination of two or more substances that are not chemically bonded together.

## Section 2: Practical Examples

In this section, we will use the theoretical concepts from the previous section to solve some real-world problems.

**Topic 3: Identifying Elements**

We can identify elements by looking at their atomic number and chemical properties. For example, iron has an atomic number of 26 and is a metal that is commonly found in the Earth's crust.

**Topic 4: Formation of Compounds**

Compounds are formed when two or more elements chemically bond together. For example, water is formed when hydrogen and oxygen combine to form H2O.

## Section 3: Self-Debating Discussions

In this section, we will use critical thinking to analyze and evaluate different scenarios related to chemistry.

**Topic 5: Environmental Impact of Chemicals**

Some chemicals can have negative effects on the environment. For example, carbon dioxide, a byproduct of burning fossil fuels, contributes to air pollution and global warming.

**Topic 6: Ethical Use of Chemicals**

Chemicals can be used for both good and bad purposes. For example, some chemicals are used to create life-saving medications, while others are used to create dangerous weapons.

## Glossary

- Atomic number: The number of protons in the nucleus of an atom.
- Element: A pure substance made up of only one type of atom.
- Compound: A substance made up of two or more different elements chemically bonded together.
- Mixture: A combination of two or more substances that are not chemically bonded together.
- Metal: An element that is a good conductor of heat and electricity.
- Nonmetal: An element that is not a metal and does not conduct heat or electricity well.
- Metalloid: An element that has properties of both metals and nonmetals.

## Conclusion

In this lesson, we learned about the basics of chemistry, including atomic structure, elements, compounds, and mixtures. We also applied these concepts to real-world scenarios and engaged in critical thinking discussions about the environmental and ethical implications of chemicals. By mastering these concepts, we can apply them to new problems and better understand the world around us.
