What actually a common sense is?

Image
Common sense is a term that we hear frequently, but what does it actually mean? At its most basic level, common sense can be defined as the ability to use sound judgment in practical situations. It is the ability to make reasonable and practical decisions based on one's own experiences, observations, and knowledge of the world. Common sense is a fundamental aspect of human intelligence and is present in individuals from all walks of life. It is the ability to make practical decisions based on a general understanding of the world and the context in which one finds themselves. Common sense is not necessarily based on specialized knowledge or training, but rather on the ability to think critically and logically about a situation. The term "common sense" is often used in contrast to specialized knowledge or academic expertise. While expertise in a particular field is important, common sense is a more general form of intelligence that is relevant to all aspects of life. Common

What and How We See, When We Close Our Eyes?

Image
When we close our eyes, we often experience a range of visual phenomena, from simple colors and patterns to more complex images and even hallucinations. These visual experiences can be both intriguing and mysterious and have captured the attention of scientists and philosophers for centuries. So, what do we see when our eyes are closed? The answer to this question is not straightforward, as the visual experiences that we have when our eyes are closed can be influenced by a number of factors, including our state of mind, our level of sensory deprivation, and our individual brain chemistry. One of the most common visual experiences that we have when our eyes are closed is the appearance of simple colors and patterns. These visual phenomena are known as phosphenes, and they occur as a result of the stimulation of the retina by pressure or electrical currents. When we close our eyes, the pressure on the retina changes, which can trigger the perception of colors and patterns. These phosphen

Chicken or Egg, Which Comes First, A Scientific Perspective

Image
The age-old question of whether the chicken or the egg came first has puzzled philosophers, scientists, and curious individuals for centuries. While this may seem like a straightforward question, the answer is not as clear-cut as one might think. From a biological perspective, both the chicken and the egg are essential for the continuation of the species. The egg provides a protective environment in which the developing embryo can grow and develop, while the chicken provides the genetic material necessary to create the egg. In order to understand which came first, we must first understand the process of egg formation. Female chickens, known as hens, have a specialized reproductive system that enables them to lay eggs. The process begins with the production of egg yolk in the hen's ovary. The yolk then moves into the oviduct, where it is fertilized by a sperm from the rooster. The fertilized egg then travels through the oviduct, where it is covered with layers of albumen (egg white)

How a human or animals obtain amino acids?

Image
 Amino acids are the building blocks of proteins, which are essential for the growth, repair, and maintenance of animal bodies. Animals obtain amino acids from the food they eat, and their bodies use various mechanisms to absorb and process them. In this blog, we will explore how animal bodies gather amino acids from their diet. Digestion: The first step in the process of gathering amino acids is digestion. Proteins in the food are broken down into their constituent amino acids by digestive enzymes in the stomach and small intestine. These enzymes break the peptide bonds that link amino acids together, releasing individual amino acids into the bloodstream. Absorption: Once the amino acids are released from the protein molecules, they are transported across the wall of the small intestine into the bloodstream. This process is facilitated by specific transporters that recognize and bind to individual amino acids. The amino acids are then carried in the bloodstream to various parts of the

Is there a Scientific Way to Predict Future Earthquakes?

Image
Currently, there is no way to predict earthquakes with certainty. However, there are certain indicators that can provide some level of insight into the likelihood of an earthquake occurring in a certain area. Scientists use a combination of seismic, geological, and geodetic data to identify areas of increased seismic activity and to estimate the likelihood of future earthquakes. Seismologists use seismographs to measure the ground movements associated with earthquakes, and they can use this information to identify areas where the earth's crust is under stress and is likely to produce an earthquake. They also use geological information to understand the history of earthquakes in a particular area and to identify areas where the fault lines and tectonic plates are most likely to move.  Geodetic techniques, such as GPS and InSAR, can also provide important information about changes in the earth's surface that may indicate increased seismic activity. Despite these advances, the abi

Earthquake and Planetary Moments

Image
Earthquakes are a natural phenomenon that has been shaking our planet for millions of years. They are caused by the movement of tectonic plates, the buildup of stress in the Earth's crust, and volcanic activity. Earthquakes release energy stored in the Earth's lithosphere, which is the outermost layer of the solid Earth that includes the crust and the uppermost part of the mantle. This energy can result in ground shaking and even cause damage to buildings and infrastructure. However, earthquakes are not just destructive forces. They also provide important information about the inner workings of our planet. By studying earthquakes, scientists can learn about the composition and structure of the Earth's lithosphere, as well as its tectonic processes. Earthquakes are one of the ways in which the solid Earth responds to the changing forces acting upon it, including the motion of tectonic plates, the buildup of stress in the Earth's crust, and volcanic activity. Earthquakes

Sequence Alignment and Research Applications

Image
Sequence alignment is a fundamental technique in bioinformatics that is used to compare and match the sequences of biological molecules, such as DNA, RNA, and proteins. The main goal of sequence alignment is to identify similarities and differences between sequences and to determine the evolutionary relationships between them. Types of Sequence Alignment There are two main types of sequence alignment: global alignment and local alignment. Global alignment involves aligning the entire length of two sequences, while local alignment focuses on aligning only the conserved regions between two sequences. Global alignment is used to determine the overall evolutionary relationship between two sequences. This type of alignment is used to construct evolutionary trees that show the relationships between different species. The most widely used global alignment method is the Needleman-Wunsch algorithm, which uses dynamic programming to align two sequences. Local alignment , on the other hand, is u

How Will You Decide Appropriateness of a better Protein Model?

Image
In protein science research, researchers are always looking to predict the structures with better accuracy. There are several metrics available, that can tell the overall nature of the model quality. One of them is the Template Modeling score or normally called TM score. Programs like I-TASSER will provide this score but unfortunately, majority of the normal users skip it. So, here I am going to tell you that what it TM and which TM score can be considered a better one.  Remember this score will always be in the range of 0-1, and for your ease 0.2 means 20% and vice versa. If you are using AlphaFold for structure modeling, I would recommend here  understanding the metrics of AlphaFold for a quality of protein structures. Template modeling score is an important metric used to assess the quality of protein structure predictions generated by template-based modeling methods such as homology modeling and comparative modeling. The score is a measure of the similarity between the predicted s

Understanding BLAST Results for Sequence Alignment

Image
BLAST (Basic Local Alignment Search Tool) is a widely used software for comparing a query sequence with a large database of sequences and finding the best matching sequences. The output of BLAST results provides information about the quality and significance of the sequence alignment between the query and the database sequences. Understanding the BLAST results is essential for interpreting the results and making informed conclusions about the query sequence and its relationship to other sequences in the database. You can use this facility here,  NCBI BLAST Server The BLAST results contain several sections that provide different types of information. Let’s take a look at each of them: Query sequence information: This section includes information about the query sequence, such as its length, number of mismatches and gaps, and the percent identity between the query and the subject sequence.  Hits list: This section lists the best matching sequences in the database, ranked by the E-value

Can You Inhibit Any Protein?

Image
No, not every protein can be inhibited. There are various factors that determine if a protein can be inhibited, including its structure, function, and interactions with other molecules. Inhibitors can be small molecules, antibodies, or RNA-based molecules, and their effectiveness varies depending on the target protein. The development of effective inhibitors is a major focus of drug discovery and chemical biology research. Proteins play a crucial role in the functioning of cells, making them a common target for drug development and inhibitory studies. However, not all proteins can be effectively inhibited, making it challenging to study their role in biological processes. In this blog post, we'll explore some of the reasons why some proteins cannot be used in inhibitory studies. Complex structure: Proteins with complex structures, such as multi-subunit complexes, can be difficult to target with inhibitors.

Computational Programs for Pocket Detection in Proteins

Image
 Active site pockets in proteins are specific regions of the protein structure where chemical reactions take place. These pockets contain specific amino acids that interact with substrate molecules and catalyze chemical reactions. They are often located in the interior of the protein and are protected from the surrounding environment, allowing the protein to selectively bind to specific substrate molecules and perform specific chemical reactions. Active site pockets are an important target in drug discovery, as they can be targeted by small molecules to modulate protein function and treat various diseases. There are several computational tools that can be used for protein active pocket detection: Molecular docking: Predicts how a small molecule will bind to a protein active site. There are a variety of docking programs available both commercial and for academic purposes (free), like  AutoDock  and  AutoDock Vina .
