Artificial intelligence in healthcare

 In this age of technology, AI (Artificial Intelligence) knows no bounds. Even though it is invoking fear in all of us, it is also benefiting most of us in various ways.

What is AI?

AI is the development of computer systems that can perform activities which require human intelligence like decision making, solving complex problems, etc.

AI in healthcare

Since the introduction of AI, it has impacted various domains such as marketing, finance, gaming industry, music, and art. However, the major impact is on healthcare. AI in healthcare is revolutionising the medical industry by providing a helping hand. It is undeniable that AI is saving lives.

AI in data management

AI helps in implementing cognitive technology to store medical records and perform power diagnosis. For example, it automates the tedious tasks of the user by implementing an automated system that would send SMS, email, etc. The use of AI based chatbot makes things easier.

AI in medical diagnosis

AI along with neural networks and deep learning is revolutionising the image diagnosis field in medicine. For example, it has taken over the complex analysis of the MRI scan and made it a simpler process.

AI in early detection

AI helps in the early prediction of medical conditions such as heart attack. AI based wearables such as Fitbit, Apple smart watch, etc. act as health trackers. They have been developed to monitor the health of a person and display warnings when devices collect unusual or unlikely data.

These smart watches collect data like heart rate, sleep cycle, breathing rate, blood pressure, etc. which are processed and analysed using machine learning and deep learning to create a model which helps in prediction of risk.

AI in medical assistance

AI based virtual nurses are developed to provide self-care and clinical advices, schedule an appointment, etc.

AI in decision making

The AI plays a major role in decision making by studying user needs and evaluating any potential risk.

The use of surgical robots can minimise errors, variations, and eventually help in increasing the efficiency of surgeons. One such surgical robot is da Vinci which allows professional surgeons to implement complex surgeries with better flexibility and control than conventional approaches.

Risk of AI in healthcare

Along with its various benefits, AI also adds potential risks in the field of healthcare. Such threats include false positives/negatives, system errors, unexplainable results, etc. In order to avoid this risk, physicians must seek training in proper usage of AI. Such training must also be incorporated as a standard component of medical education. Hospitals are also encouraged to use AI to ensure proper development, implementation, and monitoring of protocols.

With fast developing technology in this age, the human kind is to largely benefit from AI. We can reap this to the maximum extent if we are cautious about the dangers of it.

Vitamin D and homeostasis of calcium

 The bones in our body provide us support, a defined shape, the ability to make a wide range of movements, protect our vital organs, produce and maintain blood cells, and act as reservoirs for chief minerals such as calcium and phosphorus.

Some of the diseases that affect the bones are rickets (in children), osteomalacia, and osteoporosis. These diseases make the bones soft and porous, making them more vulnerable to fractures. As we age, our bones lose their density, especially in women, and this is due to the loss of calcium, phosphorus, and other minerals. 

Minerals such as calcium and phosphorus are obtained from the food that we consume and are deposited in the bones constantly. They are constantly withdrawn in order to maintain the blood mineral levels as well. This is called resorption. It is a mechanism in which tissues are broken down by specialised cells and minerals are released back into the bloodstream. This regulates a continuous cycle in which the tissues in the bones are maintained and repaired. Thus, bones act as reservoirs of minerals. 

You must be wondering about the role of vitamin D in all of this. Vitamin D is essential for the homeostasis of calcium, i.e. it regulates the calcium levels present in the blood, thus maintaining healthy and strong bones.

Let us understand this in detail. Homeostasis of calcium takes place in three major sites – intestine, kidneys, and bones. 

In the intestine, the active form of vitamin D, known as calcitriol is required for synthesising calcium binding protein (CBP), a carrier protein. CBP increases the intestinal absorption of calcium which in turn increases the calcium level in the blood. Therefore, vitamin D is said to have hypercalcemic effect.

In the kidneys, vitamin D enhances the activity of a hormone called parathyroid hormone (PTH) which is essential for the resorption of calcium. 

In the bones, vitamin D enhances the activity of osteoblasts. Osteoblasts are cells that form new bones, especially in growing children. It promotes calcium uptake and deposition (calcification) of bones. 

During hypocalcemia or calcium deficiency, in order to maintain the blood calcium level, vitamin D promotes bone resorption. It is carried out by osteoclasts, the cells responsible for the breakdown of bone tissues.

Now that you know how essential vitamin D is for our bones, you must be wondering what the best way to get vitamin D is. The answer is quite simple, it is sunlight. Getting some sunlight (about 10-30 minutes) every day is a sure shot way to ensure that we are getting our daily dose of vitamin D. Let me warn you though. There are consequences of having more than the necessary amount of vitamin D in our body. To find out about that and to know how sunlight affects the synthesis of vitamin D in our body, visit our website.

What is magnetism?

 

Magnets. Cool playthings. They attract other magnetic substances. Two magnets repel when their like poles face each other, attract when their unlike poles are brought together. We all know the basics. We also know that they are used in innumerable ways in our daily lives. In televisions, phones, microphones, refrigerators, giant cranes that lift junk cars at a scrap yard are just a few examples to begin with. But, what are these magnets and how do they get such a cool property? 

Let’s just dive right into it. Magnetism is a physical phenomenon produced by the motion of electric charges, which results in attractive and repulsive forces between objects. Yes, that’s right. It is caused by a moving electric charge. Now, we know that matter is made up of atoms and atoms have subatomic particles such as protons, electrons, etc. These charged particles create a field around them when they are in motion.

This field interacts with the field, similar to it, created by other moving charged particles present in other objects. This field or the area surrounding the object where the magnetic force is experienced is known as the magnetic field. So, simply put, magnets are objects that exhibit magnetism. 

Since all objects are made up of subatomic particles that are in motion, shouldn’t they all exhibit magnetism? To understand this, we must take into consideration a couple of things. Firstly, the magnetic field of every object/atom is not the same. For example, the magnetic field of a proton is much weaker than that of an electron. Some materials could exhibit magnetism, but due to their weak magnetic field, we may not see them moving other magnetic objects towards or away from them.

Secondly, the net magnetic field of an object/atom could be zero. Try and imagine this – every electron in motion produces a magnetic field around it. Therefore, they act as tiny magnets themselves. Now, each of these electrons has a spin, i.e. an intrinsic angular momentum.

The electrons with opposite spins (spin up and spin down) pair together while filling the electron orbitals of an atom.  In an atom with a completely filled outer electron orbital, the net magnetic field is zero as the electrons with opposite spins produce magnetic fields in the opposite direction which tend to cancel out each other. But, if an atom has a half-filled outer electron orbital, then the electrons have the same spin (either spin up or spin down) and they all produce a magnetic field in the same direction. Hence, the net magnetic field of the atom is not zero. This can be seen in atoms with one or more unpaired electrons too. 

The more popular magnetic substances are iron, nickel, and cobalt as magnets apply an attractive force on these metals. These metals exhibit a property called “ferromagnetism”. There is a history behind the name that we will explore some other time. What we need to know is that if a large number of unpaired electrons with the same spin align, they produce magnetic fields in the same direction, strong enough to be experienced at a macroscopic level. But, it is not enough that an atom or all atoms of a substance produce net magnetic fields. It is necessary that these net magnetic fields of each atom in that said substance are in the same direction for them to not cancel out each other. Chromium is an example of a metal that has a magnetic field at the atomic level, but not at a macroscopic level. What this means is, the atoms of chromium have net magnetic fields, but when a piece of chromium metal is taken, a net magnetic field is not observed. How is that even possible, right? Well, it exhibits something called “antiferromagnetism”. What is antiferromagnetism? Are there other types of magnetism than these two? There are. But, that is a topic for another day.

Importance of marking scheme and common errors committed by students

 

The videos speaks about the importance of marking scheme and common errors committed by students due to which they lose marks, although they think they have attempted right.

Marking scheme assigns a fixed proportion of the allotted marks to particular knowledge, understanding and/or skill.

While solving a problem, writing formula, substituting values in the formula, simplification, application of BODMAS rule to simplify, Writing proven statements as reasons are essential parts of the solution that fetch marks. Students can make a mistake in any of the steps mentioned. A small mistake in any of the steps could lead to deduction of marks. Example, a mistake as minor as assigning the wrong sign to a numerical while substitution or simplification might give a wrong answer.

Trigonometric ratios of 30°, 45°, and 60°

 

The monster; Trigonometry is a hard nut to crack majority of students in X grade. It is a challenging chapter, surged with formulae. Fear to solve trigonometric problems is generally considered as trigonometry phobia, which can be overcome by understanding the simple trick shown in the video. SOH CAH TOH is one of the commonly known mnemonics used for about a decade to remember the six trigonometric ratios. In addition, we have come up with a mnemonic to memorise and recall the trigonometric standard angles.

Education is not the learning of facts but the training of the mind to think

 

Einstein’s answer to one of Thomas Edison’s questions that he was once asked to answer during his stay at the Hotel Copley Plaza, Boston; “What is the speed of sound?” was “I don’t know.” He further added that he did not want to burden his mind with those facts that he could easily find in textbooks. He remarked that for a person to learn facts, he need not be a graduate. All he needs is a textbook.

Tricks to remember the prime numbers

Numbers 2, 3, 5, 7,…. are called prime numbers. Prime numbers are natural numbers greater than 1 and cannot be obtained by multiplying two smaller natural numbers. Prime numbers are important in number theory as they are the building blocks of natural numbers. Students often find it difficult to remember prime numbers after a certain range. The trick provided in the video will help them to remember the primes up to a certain range, beyond which the complexity increases.

Acronyms and Mnemonics

Acronyms are words created using the initial letters of the phrase, sentence, or list. They are pronounced as a single word.
Mnemonics help in retention of the information in the human brain.It is a tool that helps in remembering certain facts by associating it with something that is more accessible and helps in better retention of the information.

Its high time to switch to alternative sources of energy

Fossil fuels are traditionally used by humans as a source of energy. These energy sources are non-renewable and are consumed at a higher rate. All this natural resources are on the verge of depletion and moreover they also cause pollution. Therefore it is essential for every body to conserve these resources. This is possible only if we switch to alternative sources of energy.

Is sleep really essential?

A few days back, I got a scolding from mother for not going to bed on time. I was very angry and cried because I wanted to play for some more time. Finally, I had to obey my mom’s orders and go to bed. I had decided to stay awake till late at night in the bed and wake her up to prove her wrong. But when I opened my eyes, it was already morning!! I had fallen asleep within a few minutes.

I ran to the hall and asked mom “Why do we have to sleep?” She said, “Everybody, including all animals need sleep to survive and function. Sometimes we don’t realise it and then get angry for small reasons.”  “Ok. But why is it so important?” I asked. “Sleep allows our body to rest. It is very essential for learning and performing well in your work,” said mom. “Do you remember the day we came back late at night from granny’s house?” asked mom “how drowsy were you in the class? Your teacher sent a note to complain about you. Why do you think that happened?” “I was very sleepy,” I replied defensively. “Yes. Sleep is essential for alertness, maintaining all body-function rhythms, and also for your mental health,” added mom. “Was this the reason I was cranky and cried last night?” I asked. “Yes,” said mom laughingly.
I found it very interesting and decided to get some more information on sleep. In the library, I found many books on sleep. Reading one of the books, I learnt that sleep is of two types, REM and Non-REM.

I found it very interesting and decided to get some more information on sleep. In the library, I found many books on sleep. Reading one of the books, I learnt that sleep is of two types, REM and Non-REM.

Non-Rapid Eye Movement (Non-REM) sleep 

It is also known as “quiet” sleep. During this, important hormones are released for growth & development. It also helps in tissue growth and restoring energy. Maybe this is why young children sleep more than old people?

REM (rapid eye movement) sleep

During this, our eyes move back and forth very quickly beneath our eyelids, whereas the rest of our body is totally relaxed.

Do you know what I found very interesting? REM sleep is when we dream! Some scientists think that dreams help us to organise our memories and emotions. It’s like every night when we go to sleep, we transfer information from temporary cupboard to permanent cupboard (scientists call it short term memory to long term memory). 

Do you know there are five stages of sleep? They are:

1. Light Non-REM sleep 
2. Slightly Non-REM deeper sleep 
3. Deeper Non-REM sleep
4. Deepest Non-REM sleep
5. REM sleep

Repetition of alternate REM and Non-REM sleep occurs. This forms a sleep cycle. During our night’s sleep, we go through many such cycles. I read about sleep disorders such as insomnia, where people are unable to sleep due to stress. I also read about sleepwalking,  where people walk while sleeping! Isn’t that scary? What if someone goes out of the house while asleep?

When I came home and told Mom about everything that I read, she was very happy. “This is precisely why your teachers and I tell you to rest well, especially before and during exams. If your brain doesn’t get enough rest, you might not be able to do your best,” said mom.

Since that day, I sleep on time without any arguments. I also follow some practices which help me get good sleep. They are:

• Avoiding watching scary movies before going to bed
• Not drinking tea or coffee before sleeping
• Not exercising before sleeping 
• Following a schedule for sleeping

Basically, I learnt that sleep is necessary for the perfect functioning of our body. 

Ok, now it’s almost my bedtime. See you later. Good night. Sweet dreams.

Pollination by honeybees

Last Sunday, my brother and I were enjoying our leisure time reading books in our garden. Mom has planted so many beautiful plants with different coloured flowers. I got distracted by the buzzing of a honeybee. My instant reaction was to shoo it away. But my brother asked not to do so and we sat there observing the honeybee.

Honeybees look quite magnificent with their black and bright yellow colours. We watched that honeybee move from one flower to another buzzing lightly while doing so. My brother told me that the buzzing sound is because of their wings, which are smaller than their body. Due to this, they must flap their wings more frequently to fly.

He also told me many other fun facts about honeybees. Did you know that they are social insects, i.e. they live in colonies? They also have job segregation. Worker bees build hives and collect nectar, a single queen bee rules the hive, etc. They also communicate with each other via dance. But the fact which fascinated me the most was their role in the process of pollination.

We had studied in school that pollination is important for plants to reproduce. I decided to make pollination as my Sunday project and dived into gathering more information.

So, to understand the process of pollination, we must first understand the parts of a flower. I found that, in a bisexual flower, both male and female parts are present, e.g. hibiscus flower.

The male part consists of anthers and filaments. The anther contains pollen sacs which are full of pollen grains. Pollen grains come in various shapes and sizes. The female part of a flower consists of a stigma, style, and an ovary. Stigma is soft like a cushion and slightly sticky. Pollens are transferred to the stigma part of a flower. From the stigma, pollen travels to the ovary by forming a pollen tube and this leads to the formation of seeds and fruits.

Now you must be wondering, how is this related to pollination? Well, unless pollen reaches a stigma, none of the later stages of seeds and fruits formation can occur. This is where pollinators (pollen carriers) play a major role. Honeybees are not the only pollinators though. There are various agents of pollination.

Honeybees are one of the biotic agents of the pollination process. Honeybees fly from one flower to another to collect nectar, which is converted into honey by enzymatic reactions. When honeybees feed on a flower, pollen grains stick to their legs and body. When they move to another flower, they carry those pollen to the stigma. This is the process of pollination.

Pollination is of two types, self-pollination and cross-pollination.

Self-pollination is when pollination occurs by pollens produced by the same flower or another flower of the same plant.

Cross-pollination is when pollination occurs by pollens produced by another flower of the same species or different species.

Self-pollination reduces the chance factor of pollination, thereby ensuring seed and fruit production. It also maintains a pure line of genes. On the other hand, seed production in cross-pollination is less probable. However, by cross-pollination, new and better genes may get introduced which may provide evolutionary benefit to the plant. Thus, both types of pollinations are equally important.

It is important to protect pollinators, as approximately one-third of our agriculture is dependent on pollination by biotic pollinators. Pesticides, fertilizers, and increasing pollution are endangering pollinators like honeybees. We need to protect these tiny workers who help us in growing food. We can do so by reducing the use of chemicals in agriculture, reducing air pollution, practising traditional methods of agriculture, and improving bee husbandry.

So, the next time you see honeybees in your garden, instead of killing or shooing them away, you should thank them. But make sure you maintain sufficient distance because they can sting if they feel that they are in danger.

There are many more interesting facts about honeybees, like how and when do they know to dance? Why does a honeybee die after stinging someone? How exactly is nectar converted to honey? Maybe I will explore these questions in my next project.

Trick to verify the answers obtained using Factorization Method

A Quadratic polynomial is of the form ax^2+bx+c. When the standard quadratic polynomial is equated to zero, it becomes a quadratic equation. Usually, factorization method is used to find the roots of the quadratic equation, i.e. splitting the middle term. Here, two tricks are proposed to verify the roots of the quadratic equation in a very less time.

Verification of the problem is very important because sometimes the whole problem may go wrong just because the roots obtained are wrong. So, checking the answers before proceeding to the next step is important.

How to overcome the fear of maths

Maths is the base for many scientific and technological discoveries. It is one of the oldest subjects and is constantly being rejuvenated. Many of the other subjects are dependent on maths. Maths is all around us, and has an important role in our life. Right from a farmer, cook, doctor or a mechanic-everyone needs maths in their day-to-day life.

But thinking of maths gives most people jitters, they get sweaty and their heart beats faster. It’s fair to say maths is not everyone’s favorite subject. In fact, for many people, the feelings of tension and anxiety that arise when trying to solve a mathematical problem can be like hell. This is known as maths anxiety and this feeling of being a failure at maths can affect people’s mind badly.

For those who suffer with maths anxiety, it can be difficult to shift from a mindset of a failure to a more positive outlook when it comes to dealing with numbers. That is how, for many people, maths anxiety can become a lifelong issue. 

Students usually tend to inculcate fear of maths because of lack of confidence, lack of knowledge in basics, not understanding the concept properly, not studying the formulae, etc.

Here are some tips to overcome the fear of maths

1. Don’t be scared to learn formulae
   Learning formulae is very important. So, make a note of all the formulas and go through them anytime and anywhere.
2. Identify and accept the fear
   If we are afraid of anything we have to admit it, because just accepting the fear does not make you a failure. But not taking care of that fear may affect your life. Find the cause of the failure and work on it. Continuous hard work leads to success.
3. Do not try to mug up the things
   Maths should never be confused with other subjects where mugging is required. Do not byheart the formulae or solutions, try to understand the procedure and then solve the problem.
4. Do not read maths
   Do not sit and read maths like any other theory subjects. Sit and solve all the problems from the textbook.
5. Ask questions when you do not understand
   If you do not understand the concept or any problem, get your doubts cleared by a teacher or your peers.
6. Do not jump directly to the solution
   Always solve the problems step by step by understanding the logic of the problem. So that you avoid making mistakes. When one step is wrong, the whole problem will be wrong.
7. Practice the problems based on the concept
   If one thinks they know a problem very well they should practice more on that concept and should make it a rule to do each and every problem present in the textbook.
8. Make a test plan
   After practising all the problems, write a test. The test is only to measure how well you have understood the problems, and the time taken to solve the problem.

Force – An action? Or a reaction?

Have you ever fallen hard on the floor? I’m sure you have. Ever wondered why the floor is not banged up like you are? According to Newton’s third law, for every action force there is an equal and opposite reaction force. So, you must have caused the same amount of damage to the floor that you have experienced, right? We’ll find the answer to that question soon. Before that, let’s slow down for a minute and look at what exactly happens when you fall on the floor. 

You have exerted force on the floor when you fell. The floor has also exerted the same amount of force, but in the opposite direction, i.e. on you. You see a bleeding wound on your knee. But, there is no proof on the floor of your falling. 

What do you think happened to the force exerted by you? Did it get cancelled out with the force exerted by the floor on you? No. The force exerted by you is on the floor and the force exerted by the floor is on you. You and the floor are two different systems. Thus, the forces do not get cancelled out.

Is the force exerted by the floor greater than the force exerted by you? No. The action and reaction forces are of equal magnitude.

Hmm….. What could have happened then? Let us see how familiar you are with Newton’s second law. 

The acceleration of an object is directly proportional to the unbalanced force applied and in the direction of force. To break it down, acceleration can occur only when the net force on an object is not zero. In our scenario, since the forces are acting on two different systems (floor and you) the net forces on both the systems are not zero.

This is starting to become a problem now. Where did the force exerted by you on the floor go? Before you get riled up. Have you thought about the masses? Force is directly proportional to the mass of the object. The mathematical equation of Newton’s second law of motion, F = ma will answer our question. Acceleration is inversely dependent on mass, i.e. the heavier an object is, the greater force you have to apply to accelerate it. Let me try and make it more simple for you. The forces are equal, the masses are unequal; hence, the accelerations are unequal. 

As you know, the floor is attached to the building, which is attached to the Earth. Earth as a whole is so much greater than you in mass. This is the reason the effect of the force exerted by you isn’t visible on a large scale. In other words, you can see no visible accelerations on the floor’s part.

This is why some objects bounce while others don’t move even an inch. Some common examples for you to analyse are – a runner running on a road. The runner applies force on the ground and pushes backward. The ground in turn pushes the runner forward. A person sitting on a chair is applying downward force on the chair. The chair in turn is applying upward force on the person and holding him in place. The basic point we need to understand is that a single force cannot exist. Forces are always an interaction between an action and its reaction.
