Many people find photographs of albinos interesting, especially if they are not Europeans but people belonging to groups where the pigment is strongly expressed, the Chinese, Indians or Africans.. Indeed, these people do not look ordinary.. But today's story will make your blood run cold. I can't believe this is happening in the 21st century...
Albinism affects about one out of every 15,000 people in Tanzania
In some traditional communities of Tanzania and other countries in Africa, albinos, as they're often called, are thought to have magical properties, and their body parts can fetch thousands of dollars on the black market as ingredients in witch doctors potions said to give the user wealth and good luck.
One of the victims, 17-year-old Kabula, said that her attackers asked her family for money, and that her mother offered the family's bicycle because they had none. The attackers refused, held the girl down and in three hacks cut off her right arm to the armpit. Before leaving with her arm in a plastic bag, her attackers told her mother other men would be back to take her daughter's organs - but they didn't return. And this is not a single case there are many more children like her.

Today I would like to show you amazing photographs of Africans with albinism. Some of them you will find weird looking and some astonishingly beautiful.
Albinism is one of the so-called rare diseases, of which we know thousands, although each one affects few or very few people. In Europe and North America it is estimated that about 1 in 17000 people is born with one of the 20 known types of albinism.
In Europe the most common type of albinism is OCA1 (oculocutaneous albinism type 1), caused by mutations in the TYR gene. On the contrary, in Africa the most frequent albinism is OCA2 (oculocutaneous albinism type 2), produced by mutations in a gene with the same name.
Mutations appear, randomly, constantly and may affect all our genes. Sometimes, a mutation appears for the first time in a person in a community, more or less separate from the rest, and then, it is transmitted from parents to children and spreads rapidly among the members of the same group.
In Africa, this mutation is responsible for the fact that many people with albinism are not only OCA2 but also carry the same mutation.

The Hardy-Weinberg principle, established by G.H. Hardy and Wilhelm Weinberg in the early 20th century, serves as a foundational concept in genetics and evolutionary biology. It provides a mathematical model to study genetic variation in populations under ideal conditions, where allele and genotype frequencies remain constant from generation to generation in the absence of evolutionary influences. The principle has several key applications and uses in the field of genetics:
Population Genetics Baseline: It offers a null hypothesis for the genetic structure of a population, allowing researchers to identify when and how populations deviate from genetic equilibrium. This can signal the action of evolutionary forces such as natural selection, mutation, genetic drift, gene flow, and non-random mating.
Estimating Allele Frequencies: Hardy-Weinberg equilibrium equations enable the calculation of allele frequencies within a population, which is crucial for understanding the genetic diversity and health of the population.
Genetic Disorder Studies: The principle is used to estimate the carrier frequency of recessive genetic disorders in a population. By knowing the frequency of the homozygous recessive genotype (which often manifests the disorder), researchers can infer the frequency of the alleles in the gene pool, helping in disease prevalence studies and public health planning.
Conservation Genetics: In conservation biology, Hardy-Weinberg principles help assess the genetic health of endangered species populations, identifying populations at risk due to low genetic diversity or high inbreeding.
Forensic Science: Hardy-Weinberg equilibrium assists in calculating the probabilities of certain genotypes appearing in a population, which can be used in forensic case work to estimate the likelihood of a genetic match.
Understanding Evolutionary Dynamics: By comparing actual genetic distributions with those predicted by Hardy-Weinberg equilibrium, scientists can infer the roles of different evolutionary processes affecting the population.
Educational Tool: It serves as a fundamental teaching concept in genetics, helping students grasp the complexities of population genetics and the factors influencing genetic variation.
Overall, the Hardy-Weinberg principle is a critical tool in genetics for understanding how populations evolve and maintain genetic diversity, offering insights into the mechanics of evolutionary change and the genetic structure of populations.

Every one knows that In India black and dark brown eyes are most common, but other colors are also present those less common - dark brown followed by light brown, then come green and grey eyes, and the least common are blue eyes.
They are much less common than in Europe but it is still a daily occurrence to see people with light eyes in Northern and even southern states.
Rajasthanis with light eyes are very common.
Many Punjabis have light eyes, skin and hair.
In Jammu and Kashmir light eyes and skin are very common, more than any other state.
A dark skin colour and dark eye colour go hand in hand because both of them are controlled by more than one allelic regions. Eye color is a polygenic trait and there are chances of a European ancestry behind it. But, it can arise randomly due to some kind of polymorphism and mutation.
Light eyes can be found in any part of India and they are not very rare. People who are not mixed with Europeans can also have them. But the more you move in the northwest direction towards Europe light eyes and skin color get more common so there may be a connection.

Zwitterion, also known as inner salt or dipolar ion, is an ion with a positive and a negative electrical charge at different locations within a molecule. As the molecule contains two opposite charges, it is electrically neutral. The term zwitterion is derived from the German word zwitter, meaning a hybrid, hermaphrodite. Zwitterions can be formed from compounds that contain both acid groups and base groups in their molecules (ampholytes).
All of the common amino acids found in proteins are ampholytes because they contain a carboxyl group (-COOH) that acts as an acid and an amino group (-NH2) that acts as a base. In the solid state, amino acids exist in the dipolar or zwitterion form. If acid is added to a solution containing the zwitterion, the carboxylate group captures a hydrogen (H+) ion, and the amino acid becomes positively charged. If base is added, ion removal of the H+ ion from the amino group of the zwitterion produces a negatively charged amino acid.
In a neutral solution, most amino acids exist as:
A) positively charged compounds.
B) zwitterions *
C) negatively charged compounds
D) hydrophobic molecules.

Have you eve seen albino chinese? They do exist. Official data showed that in 2018 there were almost 90,000 albinos in mainland China. According to sciencedirect in 2018, the rates of albinism in the country were around one in every 18,000 people.
Albinism is a rare genetic condition characterized by a lack of melanin, the pigment responsible for hair, skin, and eye color. Inherited in an autosomal recessive pattern, it means both parents must carry the gene to pass it to their child.
They may experience vision problems and are sensitive to sunlight due to low melanin. Albinism is not curable, but managing its symptoms and protecting the skin and eyes from the sun is crucial. Understanding albinism's genetic roots helps dispel myths and promotes acceptance in society.
In China, for example, the disorder is considered bad luck, leaving people with albinism ostracized and excluded from mainstream society. There's no schooling, no job prospects, and rarely marriage or family.

Micropipettes are indispensable tools in laboratories, and using them correctly with the right tips is essential for obtaining accurate and reproducible results. Here, we'll explore the importance of micropipette tips, how to choose the right ones, and best practices for their usage.
The Significance of Micropipette Tips:
Micropipette tips, also known as pipette tips or pipette nozzles, play a crucial role in the precision and reliability of liquid handling in a laboratory. These disposable, often plastic, attachments are designed to fit the specific micropipette model and volume range. The significance of micropipette tips lies in several key aspects:
Contamination Prevention: Micropipette tips create a barrier between the pipette and the sample, preventing cross-contamination between different solutions. Using a fresh tip for each sample eliminates the risk of carryover.
Accuracy: Tips are calibrated to work with specific micropipettes and volumes. Using the correct tip ensures that the desired volume is aspirated and dispensed accurately.
Sample Integrity: Many tips are designed to be low-retention, meaning they minimize sample residue left behind. This feature is especially valuable when handling precious or small-volume samples.
Choosing the Right Micropipette Tips:
Selecting the appropriate micropipette tips is critical for ensuring the accuracy and precision of your work. Here's how to choose the right ones:
Tip Volume Range: Ensure that the tip's volume range matches the volume you intend to pipette. Using a tip with the wrong volume range can lead to inaccurate measurements.
Tip Material: Consider the compatibility of the tip material with your samples. Standard plastic tips are suitable for most applications, but specialized materials like filtered tips or low-retention tips may be required for specific assays.
Sterility: When working with sensitive biological samples, select sterile tips to prevent contamination.
Tip Design: Some tips are designed with features like extended length or filter barriers to accommodate unique applications or prevent aerosol formation.
Best Practices for Using Micropipette Tips:
To maximize the effectiveness of micropipette tips, follow these best practices:
Use Fresh Tips: Always start with a new, uncontaminated tip for each sample. Replace tips between sample transfers to avoid cross-contamination.
Proper Attachment: Ensure that the tip is securely attached to the micropipette to prevent leaks or spills.
Pre-Wetting: For accurate low-volume pipetting, pre-wet the tip by aspirating and dispensing the liquid several times. This helps eliminate air gaps and ensures precise measurements.
Avoid Touching the Inside: Touch only the outer surface of the tip to prevent contamination of the sample or tip.
Eject Tips Correctly: Use the designated ejection mechanism on the micropipette to remove tips without manual contact. This prevents the risk of sample or tip contamination.
Dispose of Tips Properly: Dispose of used tips as biohazard waste according to your laboratory's guidelines.
Regular Calibration: Periodically calibrate and maintain your micropipettes to ensure their accuracy and precision. This includes calibration with specific tips.
Micropipette tips are essential components of precise liquid handling in laboratory settings. By choosing the right tips and following best practices, you can maintain the integrity of your samples and achieve reliable results in your experiments and analyses.

Water Potential Definition
Water potential is the potential energy of water in a system compared to pure water, when both temperature and pressure are kept the same. It can also be described as a measure of how freely water molecules can move in a particular environment or system. It is measured in kilopascals (kPa) and is represented by the Greek letter Psi (Ψ). Water potential is never positive but has a maximum value of zero, which is that of pure water at atmospheric pressure. When it comes to impure water, or water that has solutes in it, the more solute there is, the more negative Ψ becomes, since the solute molecules will attract the water molecules and restrict their freedom to move.
Movement of Water Molecules
Water moves from areas of where water potential is higher (or less negative), to areas where it is lower (or more negative), and we refer to this movement as osmosis. For example, in the diagram below, the solution around the cell is hypertonic, meaning that it has a higher concentration of solute, so a lower water potential, than the inside of the cell. Since the cell has a partially-permeable membrane, allowing the movement of water in and out of it, water will move from inside of the cell, where Ψ is higher, to outside of the cell, where Ψ is lower. This can lead to the death of cells in living organisms. On the other hand, a cell that is placed in a pure water solution could take up water until it bursts and dies. Therefore, cells need an environment that does not differ significantly in its solute concentrations.
Water potential is what allows water to get into plant roots when there is more solute within the root cells than the water in the soil. And as we go up the plant, Ψ decreases more and more, drawing water into the stems and then the leaves, which constantly get water evaporated out of them, maintaining a high solute concentration and a low Ψ. In our bodies, solute concentration is regulated through osmoregulation, which controls and maintains water and salt concentrations to keep us alive.
Questions:
What can we expect to observe if we place a cell inside a solution where the cell’s water potential is equal to -0.3 kPa and that of the solution is -0.9 kPa?
A) Water will move out of the cell *
B) Water will move into the cell
C) Water will not move into or out of the cell
D) The cell will burst

Micropipettes are indispensable tools in laboratories and research settings, enabling accurate and precise liquid handling for a myriad of applications. Whether you're a seasoned scientist or a novice researcher, understanding how to properly set and read micropipette volumes is essential for reliable experimental results. In this article, we will guide you through the step-by-step process of setting and reading micropipette volumes like a pro.
Step 1: Familiarize Yourself with the Micropipette
Before you start using a micropipette, it's crucial to understand its components. A typical micropipette consists of a plunger button, a volume adjustment dial, a tip ejector, and the tip itself. Each component plays a vital role in accurately transferring the desired volume of liquid.
Step 2: Set the Desired Volume
Adjustment Dial: Rotate the volume adjustment dial to set the desired volume. Make sure to set it to the volume specified by your experimental protocol.
Volume Lock: Some micropipettes have a volume lock to prevent accidental changes in the set volume. Engage the volume lock if your micropipette has one.
Step 3: Attach a Tip
Select a compatible pipette tip that corresponds to the set volume. Gently press the micropipette down onto the tip, ensuring a secure attachment.
Step 4: Aspirate the Liquid
Plunger Button: Depress the plunger button down to the first stop to aspirate the liquid into the tip. Make sure the tip is fully immersed in the liquid.
Slow Release: Gradually release the plunger button to the original position. This will create a seal and hold the liquid in the tip.
Step 5: Dispense the Liquid
Position the tip at the desired destination for liquid dispensing.
Plunger Button: Depress the plunger button to the first stop to begin dispensing the liquid. To fully dispense the liquid, depress the plunger to the second stop.
Eject Tip: After dispensing, press the tip ejector button to safely remove the used tip.
Reading the Volume Display
Most micropipettes have a digital volume display that indicates the set volume. Read the volume display carefully, ensuring that you have set and aspirated the correct volume. Some micropipettes have a separate decimal point indicator, so be attentive to both the main digits and the decimal point.
Tips for Accurate Pipetting:
Pre-Wet Tip: Before aspirating the liquid, pre-wet the tip by aspirating and dispensing the liquid once without touching any surface.
Consistency: Maintain a steady and consistent speed while depressing and releasing the plunger to ensure accurate volume measurement.
Avoid Air Bubbles: To prevent air bubbles, always keep the tip submerged in the liquid while aspirating, and dispense liquid against the container wall to avoid bubble formation.
Calibration: Regularly calibrate and maintain your micropipettes according to manufacturer guidelines to ensure accurate volume delivery.
Conclusion
Mastering the art of setting and reading micropipette volumes is a fundamental skill for any researcher or scientist. By following the step-by-step process and adhering to best practices, you can confidently handle micropipettes and ensure precise liquid transfers in your experiments. Accurate pipetting not only enhances the reliability of your results but also contributes to the overall success of your scientific endeavors.

Today I'm going to show you how albino Indians look like.Some people think the whole India is brown and black! And more related to Negroids, Australoids or Mongoloids.
This is not true - absolute majority of them belong to caucasoid group. Actually color has less to do with race, race is actually about your head bone structure, facial features, body bone structure. Melanin content can change your skin tone but your race only can change during long term evolution.
Take case of albino Indians - they look like north Europeans - even I would say scandinavians.
Look at this man - I think he looks a lot like Theon Greyjoy from Sereal Game of Thrones.
Or take a look at this albono indian peasant man he look like a member of brithish family like another brother of price Harry.

India is like acontinent which had 3 races before migration/invasion of steppe people (some consider them aryan, some consider native Indus people as aryan and steppe as older wave of sakas) So before migration India had mongoloid race in east, dravidoid in south, Iran neolithic in north west. With migration of steppe the 4th race entered into India.
All three races are sub-races of caucasoid race and dravidian considered to be aboriginal population of India.
Now take a look at the Steppe, the reconstructed picture in right represent man from yamnaya civilization(which was early middle bronze age steppe civilization), man in left is professor niranjan from Palwal who is JAT. Again we can see similarity between steppe reconstructed face and JAT man since jats have high steppe ancestry. Eyes, nose, lips, forehead, lips,etc all are similar in both picture.

Amino acids are organic compounds that serve as the building blocks of proteins. They play a crucial role in various biological processes. Here are some key points about amino acids:
Basic Structure: Each amino acid consists of a central carbon atom (the alpha carbon), an amino group (-NH2), a carboxyl group (-COOH), a hydrogen atom, and a distinctive side chain (R-group) that varies between different amino acids.
Types of Amino Acids: There are 20 standard amino acids commonly found in proteins. These are alanine, arginine, asparagine, aspartic acid, cysteine, glutamine, glutamic acid, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, and valine.
Essential Amino Acids: Of the 20 standard amino acids, nine are termed essential for humans because they cannot be synthesized by the body and must be obtained from the diet. These include histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
Roles in the Body: Amino acids are involved in various metabolic processes. They are the building blocks of proteins, which are crucial for body functions like cell structure, transport, enzyme activity, and as precursors for neurotransmitters and hormones.
Protein Synthesis: During protein synthesis, amino acids are linked together by peptide bonds, forming long chains that fold into specific three-dimensional structures, which determine the function of the protein.
Dietary Sources: Amino acids are obtained from protein-rich foods such as meat, fish, dairy products, eggs, and plant sources like legumes, nuts, and grains.
Supplements and Medicine: Certain amino acids are used in dietary supplements and medications due to their role in muscle growth, immune function, and neurotransmitter regulation.
Biochemical Properties: Amino acids can be classified based on the properties of their side chains, such as nonpolar, polar, acidic, and basic.

The Impact and Importance of HPV Vaccination
Human Papillomavirus (HPV) vaccination represents a significant advancement in public health, targeting a virus linked to several cancers and genital warts. HPV is one of the most common sexually transmitted infections globally, with certain strains being high-risk factors for cancers such as cervical, anal, and oropharyngeal cancer.
What is HPV?
HPV encompasses over 100 virus types, with around 40 affecting the genital areas. These are broadly categorized into 'low-risk' types, which can cause genital warts, and 'high-risk' types, associated with cancer. The infection is often asymptomatic, making it difficult to detect and control its spread.
The Vaccine’s Role
The primary goal of HPV vaccination is to prevent infection by the high-risk HPV types. The most common vaccines, like Gardasil 9, protect against several strains, including HPV types 16 and 18, which are responsible for the majority of HPV-related cancers. The vaccine is most effective when administered before individuals become sexually active, leading to its recommendation for pre-teens as part of routine immunization schedules.
Effectiveness and Impact
Studies have shown that the HPV vaccine is highly effective in preventing infections, precancerous lesions, and genital warts caused by virus types covered by the vaccine. This effectiveness has translated into a substantial decrease in HPV infections and related conditions in populations with high vaccination rates. For instance, countries with robust HPV vaccination programs have reported significant drops in the incidence of cervical cancer and genital warts among the vaccinated population.
Safety and Accessibility
The HPV vaccine has a strong safety record, with typical side effects being mild and similar to other vaccines (e.g., pain at the injection site). Efforts continue globally to improve access to the vaccine, especially in low and middle-income countries where the burden of HPV-related diseases is highest.
Conclusion
HPV vaccination stands as a critical tool in cancer prevention strategies. Its widespread adoption and integration into national immunization programs can lead to significant public health benefits, potentially reducing the global burden of cancers associated with HPV.

This way of expressing a dilution as a ratio of the parts of solute to the total number of parts is common in biology. The dilution factor (DF) can be used alone or as the denominator of the fraction, for example, a DF of 10 means a 1:10 dilution, or 1 part solute + 9 parts diluent, for a total of 10 parts.
Problem:
If you've taken 250 ml of plasma and added 750 ml of distilled water, you have achieved 1:3 dilution.

Hybrid vigor, also known as heterosis, is a biological phenomenon where the offspring of two different species or varieties exhibit traits that are superior to those of both parents. This concept is most commonly applied in the context of plant and animal breeding. Here are some key points about hybrid vigor:
Increased Performance: Hybrids often show greater strength, higher growth rates, improved fertility, and other enhanced qualities compared to their parents. This can include better resistance to diseases, pests, and environmental stresses.
Genetic Diversity: Hybrid vigor occurs due to the increased genetic diversity that results from crossing two different breeds or species. This diversity can lead to a combination of genes that works better together than the genes of either parent in isolation.
Dominant and Recessive Genes: One explanation for hybrid vigor is that harmful recessive traits are masked because they are less likely to be paired with identical recessive traits from the other parent. Meanwhile, beneficial dominant traits from both parents are expressed.
Agricultural Importance: In agriculture, hybrid vigor is exploited to improve crop yield and quality. Many of the crops grown today, such as corn (maize), are hybrids specifically bred for enhanced traits.
Animal Breeding: In animal breeding, hybrid vigor is used to create healthier and more productive livestock. It's also seen in domestic animals like dogs, where mixed-breed dogs often have fewer health problems than purebreds, due to a wider genetic pool.
Temporary Effect: The phenomenon of hybrid vigor typically applies only to the first generation (F1) hybrids. When these hybrids are further bred, the subsequent generations may not retain the same level of enhanced traits.
Not Always Beneficial: It's important to note that hybrid vigor is not guaranteed in all crosses. The success of creating hybrids with desirable traits depends on the genetic compatibility and characteristics of the parent breeds or species.
In summary, hybrid vigor refers to the superior qualities exhibited by hybrid offspring, resulting from genetic diversity and the combination of traits from different parent lines. This concept is widely used in agriculture and animal breeding to enhance productivity, health, and other desirable characteristics.
