Why you (and everyone else…) call her ‘mom’

You are 10 years old again, and you’re at the grocery store with your mom. The reese’s pieces in aisle 4 caught your eye, but just for a second. You turn around to ask your mom to if you are allowed to get them, but she has disappeared. Frantically, you call out, “Mom!”, but you recoil when nearly every woman in sight turns to find out who was calling their name.

If you wanna talk about ambiguity, the term ‘mom’ pretty  much nails it. Did you ever think how strange it is that nearly everyone in the english speaking language refers to their mother by the exact same name? Even more odd: the name ‘mom’ (ok, slight variations of the name) are common across many languages and cultures.

Example of terms of kinship in English and Spanish

It’s hard to talk in terms of genealogy (or, the study of family history) without using terms of kinship, such as father, auntie or grandma. These words are crucial in describing blood relations to each other; ultimately, terms of kinship are the foundation when  constructing family trees. However, these terms often translate very differently in terms of phonetics. For example, in English we refer to the brother of our father as ‘uncle’, whereas in Spanish he is referred to as ‘tío’.  You see, these two words do not look or sound the same. However, there is something about the term mother that is all too similar across many languages….

In German, they say ‘mutter’. In Afrikaans, it’s ‘moeder’. Swahili? Mama. Catching the drift?

So how did the kinship term ‘mother’ turn out to be so phonetically similar across cultures? Most experts have landed on an explanation provided by Roman Jakobson, and it goes like this:

“Often the sucking activities of a child are accompanied by a slight nasal murmur, the only phonation which can be produced when the lips are pressed to mother’s breast or to the feeding bottle and the mouth full. Later, this phonatory reaction to nursing is reproduced as an anticipatory signal at the mere sight of food and finally as a manifestation of a desire to eat, or more generally, as an expression of discontent and impatient longing for missing food or absent nurser, and any ungranted wish”

I mean, that makes perfect sense, right? But what if I told you that Jakobson presented these findings in 1962, over 50 years ago. The literature on this specific topic hardly goes past the early 90’s, and while Jakobson’s explanation may seem to be bang-on, I am curious if the scientific community has not questioned this explanation thoroughly enough; the biggest flaw I see is how this accounts for all the languages that do not have a phonetically similar variant of ‘mother’.

While some are ready to mark this topic case-closed, I would prefer to leave it open to allow the scientific community to explore it a little longer.

Sniffing with your knee!

Have you ever thought to replace your knee with a tissue in your nose? Well, as we know most of the skeleton of a new born baby is of cartilage. There are three different types of cartilage, and depending on the function that each organ in our body is doing, it can have one or combination of these types of cartilage.

Our knee joint is consisted of the junction of three bones ( Femur (upper leg), Tibia (lower leg) and Patella (kneecap)), and some different ligaments (bone to bone connectors), and different type of cartilages.

Articular cartilage (type of Hyaline cartilage: cartilage with glossy appearance) prevents the two bony surfaces of Tibia and Femur to be in direct contact with each other. Different factors such as age, autoimmune disease (when our own immune system attack different organ of our body, in this case the joint), or sport injury can damage and destroy the articular cartilage in the knee joint.

In consequence, a harder tissue, which does not have the functionality of the cartilage, will replace it, so the person will suffer a lot and will be in sever pain. Until recent years the treatments were mostly drug therapy (anti inflammatory drugs and pain killers), and artificial joint (Knee Replacement Surgery). However, none of these methods can solve the problem completely, and the patients will have limited functioning in their joint the rest of their lives. About two years ago, some scientist decided to try a new treatment method; in this method, they cut part of the nose cartilage, which has the same characteristics of the knee cartilage, grew it outside of the body, then grafted it to the knee joint. This was done in some animals like goats first, and recently was tested on human which has had satisfactory results. I think this treatment can help many patients to back to their normal lives with no pain. As a result, the patients will not need the pain-killer drugs. Therefore, they can not only save money by not spending it for the drugs , but also can prevent the long-term side effects of the drugs on their bodies. It can also decrease the cost of health care system and save tax payers’ money.

 

 

 

The Effects of Sleep Deprivation

A growing percentage of college students do not sleep enough because of many reasons. Some students are taking too many credits and participating in different extracurricular activities. Other students have to work for hours to pay for their school. Although college students can shorten their sleep time and save the time for other activities, they are supposed to realise that they should not do it. A recent published scientific article, Partial sleep deprivation activates the DNA damage response (DDR) and the senescence-associated secretory phenotype (SASP) in aged adult humans, has shown that insufficient sleep is linked to cell damage which may contribute to an increased risk of chronic disease. Another study, The influence of sleep deprivation and obesity on DNA damage in female Zucker rats, has indicated that prolonged and regular sleep deprivation can kill up to 25% of certain brain cells on those mice in the experiment. Sleep deprivation is associated with genetic damage in brain cells in some levels to human beings. Since the damaged brain cells require a long time to heal, college students are supposed to get enough sleep on a regular basis to ensure their brains can have a good rest.

What causes lack of sleep?

Some people do not realise the importance of adequate sleep, so they choose to stay up late to socialise or watch television shows. For individuals who are busy with work, frequent travelling tends to disrupt their regular sleep circles. Moreover, health problems such as snoring, sleep apnoea can disturb people’s sleep many times during the night. People who have these problems always wake up without feeling rested or refreshed. The sleeping environment is another factor that has the effect on sleep. People usually are not able to sleep well if their bedrooms are too hot or too cold or they have noisy neighbours. Some life habits can also be disruptive. For example, drinking coffee or listening to electronic music close to bedtime make people sleep less likely.

Consequences of insufficient sleep

Poorer health condition is the price of inadequate sleep.  Researcher have indicated that obesity, heart disease, high blood pressure, diabetes, and frequent mental distress are associated with sleep loss. Also, lack of sleep impairs people’s performance. People who need eight hours sleep per night only get six, they have the poorer concentration on their daily work comparing to their peers. For students who give up sleep and study for the whole night, they are less likely to get better grades because sleep loss slows their reaction time and makes them have poorer memory.

Sleep tips

Research shows that students who sleep more get better grades. I have some advice for college students and adults who suffer sleep loss. You may drink warm water or milk before you go to bed. Warm milk helps people fall asleep and sleep better. You can also remove distractions in the bedrooms such as game players or computers, and shut down all digital devices while sleeping. Last, try not to consume too much alcohol or caffeinated beverages hours before bedtime.  

Please watch the video below and check how sleep deprived you are.

The Atmosphere of Earth Is Leaking Oxygen

Although oxygen composes 21% of the Earth’s atmosphere, oxygen levels are not stable. Through analysis of air bubbles caught inside ice cores (core samples of ice taken from ice sheets or glaciers) in Greenland and Antarctica, Princeton University researchers determined that oxygen levels dropped 0.7% over the past 800,000 years.

The full research article was published in the September 23 issue of Science journal. While the researchers are not sure why the oxygen drop occurred, researcher Daniel Stolper believes that it is due to the increase in global erosion rates. Erosion is the process in which earth is worn away, often due to processes like rain or wind. Grinding of rocks by glaciers (large bodies of ice that move under their own weight) results in erosion, and the growth of glaciers over the past tens of million years has increased Earth’s erosion levels.

How does erosion relate to oxygen levels? Erosion would expose increased pyrite and organic carbon to the atmosphere.

Pyrite, colloquially known as “fool’s gold” for physically resembling gold, reacts with oxygen and removes it from the atmosphere. Organic carbon has been found to do the same thing.

In terms of immediate impact on Earth, the drop is trivial because of how slow it is. Organisms have had time to adapt to the change in atmospheric oxygen. However, atmospheric oxygen levels are linked to climate change and how organisms evolve, so understanding its trends is important. For example, changing oxygen levels can alter how living things adapt, and from an evolutionary standpoint, declining oxygen levels would prefer individuals and species who are more efficient with their use of oxygen.

Understanding oxygen levels can also be the key to understanding long-term weather trends, and further research could determine if there are any links between this observation about oxygen levels and the global warming crisis that we are facing today.

In addition, understanding the processes behind the declining oxygen levels and observing how living things have adapted to it over time could help humans understand what is needed for a habitable environment. With continued efforts to build a feasible human settlement in Mars, having a better grasp of what is needed for life on Earth would be important if humans are ever to colonize Mars. As lack of atmospheric oxygen is one of the major obstacles to life on Mars, understanding how living things on Earth react to lower levels of oxygen could allow for potential ideas on how to survive in Mars’ low-oxygen conditions.

Therefore, although these findings do not have an immediate impact on Earth, they carry big implications both for humanity’s future and understanding our planet’s past.

Why haven’t we found a vaccine for HIV?

In 1984, after the cause of AIDS was discovered, US Health and Human Services Secretary announced that a vaccine for HIV would be available in two years time. Three decades later, more than eighty clinical trials and over thirty prospective vaccines to date, the virus is still winning!

Why is it such an impossible task to create an effective vaccine against HIV? A task that seems to have disheartened many researchers from striving to find the solution to a persistent pandemic! Without a cure for AIDS, a vaccine is the only way to slow it down. So far, a total of 78 million people have been infected with HIV and although the number of new infections per year has dropped from 3.4 million as recorded in 2001, it has stagnated at 2.1 million since 2013; a number that is still considerably high. Therefore, with millions of dollars being allocated to HIV vaccine research annually, why is a breakthrough still lacking?

Normally, vaccines are composed of a harmless form of the virus or parts of it such as surface proteins; these stimulate immune cells to produce compounds known as antibodies that bind a small part of the virus component called an epitope; the attachment deactivates the virus preventing it from invading healthy tissues and causing disease. Vaccines also activate immune cells that kill infected cells.

However, successful in controlling more than 30 most contagious illnesses, this vaccine is defective when it comes to HIV. This is because HIV like the common cold virus undergoes numerous errors when replicating it’s DNA. Therefore, HIV’s epitopes are very prone to changing. Due to the high specificity of antibodies and ‘killer’ cells, viruses that have changed epitopes cannot be deactivated by the same antibodies and ‘killer’ cells. This property of HIV makes it very challenging to create an effective vaccine. Despite being weakened, using live HIV as a vaccine is also gravely concerning; it could possibly evolve into a virulent form as the virus is constantly mutating. HIV particles are also by nature very different despite being incredibly mutable. This is because they descend from numerous ancestors. For an effective vaccine to be created, its breadth should be large enough to account for all HIV variants.

Another setback in the development of HIV vaccine is the fact that AIDS recovery is rare; vaccines are usually geared to mimic the immune response generated by our bodies after infection and recovery from the subsequent disease. In the case of HIV, the body cannot develop this immunity as HIV attacks immune cells. Lastly, HIV integrates its DNA with ours and becomes a part of us! This gives ‘killer’ cells a hard time detecting infected cells where virus assembly takes place. These factors among others are what have stalled HIV vaccine development.

Despite the challenges, we are all capable of taking preventative measures to prevent further spread of the virus. To learn more on how to protect yourself, click here.

32 Pearls

 

If not the hardest, teeth are one of the most solid parts of the human body. There are four different types of teeth in our oral cavity including incisors, canines, premolars, and molars. Either individually or collectively they are responsible for many different functions including mastication (chewing), pronunciation, and aesthetic in our body. Without being able to chew properly, we cannot digest our food, malnutrition, so we will be weak and eventually die. We also use our teeth to help in articulating certain sounds like ‘f’. Having healthy teeth, in addition, can add to our attractiveness, and in some instances, they can have direct influence on the our personal and professional lives.

Therefore, damaged or missing teeth can cause serious problems for us, and it is beneficial to know the ways they got damaged and ,consequently, lead to their death.

Oral Cavity, Image credit: Wikipedia, https://blogs.ubc.ca/communicatingscience2016w109/files/2016/09/Illu_mouth.jpg

there are two main causes of damage to our teeth: infection and trauma.

Infection:

There are about thousands of different bacteria residing in our mouth, and they can cause infection in our teeth. Each tooth consists of three main parts: enamel, dentin, and pulp (root).

As long as the outer surface of our teeth (enamel) is intact, the tooth can stay alive. However, as a result of different factors such as poor hygiene, these bacteria can dissolve the enamel, penetrate to inner chamber (pulp), and cause infection. Consequently, our defence system will attack this infection the same way, inflammatory response, it attacks any other infection in our body. The ultimate goal of this response is to kill the bacteria. However, since the pulp has very tiny space, the inflammation will cause the blood supply to the pulp to be cut off. As a result, the infected tooth will not receive the nutrients and oxygen necessary to survive, and it will die.

Trauma:

Any physical impact in different accidents such as car crashes, or sport injuries can damage our teeth and eventually lead to their death. Our teeth, in both upper and lower jaws, are connected to their bony sockets via periodontal ligaments, which means they are not fused to the bone. Severe physical impact can dislocate them either completely (falling off), or partially. In either case, it will shut down the blood supply to the effected tooth and lead to its death. In case of children who still have their milk teeth, the root of dislocated teeth can damage the permanent tooth germ under it and prevent its growth permanently.

Being aware of these two main causes of damage can help us to prevent them as much as possible and take care of our teeth as pearls.

Can animals feel as we do?

Critical thinking, opposable thumbs, and cell phones are one of the many things that differentiate us from animals in the wild and nature. A common belief is that emotions are one of those things but certain studies say otherwise. Emotions, like fear, anger, and anxious, are examples of emotions believed to be exclusive to human behavior and animals with similar brain anatomies like other mammals that share similarities in their brain physiology and chemistry. Despite it being well-known that other mammals can display certain human-like emotions, we still don’t know if non-mammal animals such as bees, insects, and fish have similar ’emotions’.
Researchers backed by Newcastle University did an experiment where they submitted bees to an anxiety-producing environment by vigorous shaking their enclosure. The experiment was designed to replica a predatory attack to see if the bees displayed negative patterns of deviation in judgement. By using these patterns of deviation in judgement as a measure of emotions in the bees, the bees would be considered exhibiting emotions due to the results.

bees-experiment

“A bee enters a cylinder with an ambiguous reward in the study of bee “feelings.” – Clint J. Perry

Another experiment was done to see if crayfish would display anxiety-like emotions like mammals do when given chemical injections of serotonin. The results were that the crayfish displayed a form of anxiety that shared similarities with complex human-like emotions present in many vertebrates.

Lastly, a study was done in 2015 by Brian Key at the University of Queensland to see why fish do not feel pain as humans do. The experimenter used a bio-engineering principle that structure determines function. He located the area of the human brain that is responsible for a person feeling pain and mapped out the structure features and shape of that part of the brain. He then compared the identified structures to a fish brain to see if the fish was anatomically capable of feeling pain. The results were that the fish lacked the necessary brain structures to feel pain therefore fish can not feel pain at least in the same way humans do.

Emotions, despite there being clear-cut definitions produced by various science communities, are still very loosely defined in respects to the general public. Regardless of what the general public, non-science specialists, and even certain scientists say, I along with most other scientists who have conducted these studies believe more studies need to be done and new ways to examine emotions in animals need to be developed in order to further analyze the possibility that these ‘wild’ animals display emotions like humans do. Our current understanding of the functionality and anatomy of other animals’ brains and even the understanding of own brain functionality and anatomy are not complete so that means we can’t many definite statements regarding the question of whether animals have the same complex emotions that humans do.

Can Polar Bears Survive by Switching Their Diet?

Climate change is not a new topic. We can even feel the temperature increasing according to the hotter summer and warmer winter. I once came across the article  and it has since then provoked my thoughts on a question: “Have we ever cared about polar bears?”

A frame-filling portrait of a male polar bear (Ursus maritimus) jumping in the pack ice. Svalbard, Norway. Retrieved from https://en.wikipedia.org/wiki/Polar_bear

I have read some articles and blogs regarding polar bears and their survival under global warming. Some claim it is not necessary to worry about polar bears. They successfully switched their major prey from bearded to ringed seals in the past due to abundance changes of the two species in Hudson Bay. Similarly, they should be able to switch their diet from marine foods to terrestrial foods once again.

In fact, research has shown that polar bears’ feeding on terrestrial foods are  more common recently, because land-based foods are becoming the most available food source. For instance, polar bear predation on snow geese was first observed in 1900s. Their reliance on snow geese in Arctic regions has been largely increasing for the past century .

In my opinion, however, the idea that polar bears can survive under global warming by switching their major prey may be overly hypothetical, because food resources containing sufficient energy are not available on shore, making it impossible for polar bears to survive the increased time on land.

Retrieved from https://en.wikipedia.org/wiki/Polar_bear

Retrieved from https://en.wikipedia.org/wiki/Polar_bear

We can survive in a hot summer by turning on our air conditioners, but polar bears cannot. Some scientists project that by 2050s, the global polar bear population will shrink to one third of the current figure. Therefore, the conservation of polar bears and stopping global warming deserve more attention and timely responses from the society.

CRISPR; A tool that can almost fix everything

CRISPR, sounds like a type of vehicle or a new gym supplement. In fact CRISPR is a new piece of technology, possibly the greatest finding of the century. CRISPR, short for Clustered Regularly Interspaced Short Palindromic Repeats, is a genome-editing tool that was first found in bacteria. Japanese scientist Yoshizumi Ishino at the University of Osaka was the first to discovered CRISPR in 1987.

CRISPR is used as part of the immune system defence in bacteria. It has the ability to sense when viruses inject their DNA into the cell; sending out proteins that recognize the foreign DNA, cutting it up into non-functioning pieces to prevent an infection. The sent out proteins are able to recognize virus genomes by incorporating the injected viral DNA into its own genetic material, using this as a template to find the invading DNA.

Many of you may be thinking, cool so the bacteria has a way of protecting itself from invading viruses but how does this effect humans? Until now there have not been accurate DNA cutting technology but with CRISPR we have one. As discovered by Doudna Lab, it is possible for scientists to create templates that match the gene they want to remove from genetic material, allowing them to cut out any gene they want. For a concise explanation check out Carl Zimmer’s, on behalf of  BI science, description of how CRISPR works in the video below.

This allows for endless possibilities. Genetic diseases, like sickle cell anemia, can be cured using CRISPR. Simply make a template that matches the mutated gene, remove it with the CRISPR  and add a functional gene. The individual will no longer suffer from sickle cell anemia. Scientists are even looking at the possibility to modify the human germ layer, allowing for ‘designer’ babies to be made. We are still a long way from designer babies though, as it is illegal to do genetic experiments that alter the germ layer in many countries, as well as the possibilities of errors arising during the procedure that have not been fixed.

Scientists are also exploring CRISPR’s applications on plants. Want to produce plants that can survive harsher climates and produce better products, modify the genome by removing and inserting genes of interest. For instance, the State University of New Jersey is working with grape plants to edit their genes to be resistant against fungus using CRISPR.

Unfortunately CRIPSR technology won’t be used for several years. Research is only being done on animal models and human cells right now, as the errors of CRISPR are still trying to be fixed along with arguments around it’s ethics. The templates made to match genes may accidentally match up with similar genes in the body, which would lead to mutations in human genes that could potentially be fatal. Although still under work, CRISPR has the potential to cure many diseases and provide a higher quality of life for everyone.

Not a myth: women are better at multitasking

How different is our brains? why men are better at reading maps while women are better at multitasking?

Nowadays, with the advent of internet and the significant advances in science and technology, the necessity of multitasking in order to save time has become more pressing than ever. A recent study looking at the “connectomes” of the sexes, has confirmed what we have known all along – men and women think differently. Our brain is one of the most complex organs in the body comprised of different segments; cerebrum and cerebellum which are responsible for thinking and actions respectively. Both cerebrum and cerebellum are divided into right and left hemisphere. The left hemisphere is responsible for logical and mathematical thoughts while the right hemisphere deals with feelings and intuitions.

sex-differences-brain

Researchers from University of Pennsylvania conducted a study on the brain of 521 females and 428 males and revealed the facts behind the better performance of women in multitasking which is due to the pattern of connections between different parts of their brains. As we see in the picture the connections in men’s brain (top) in cerebrum are different from those in women’s brain (bottom).Generally speaking, women’s brain have higher connectivity between the left and right hemispheres, whereas men’s brain has more connections between back and front within a hemisphere. The only Region where men have more left to right connections compared to women is in the cerebellum that plays a crucial role in motor control.

The specific patterns of connections are the best explanation for the functional differences between men and women. The cross connections between the two hemispheres in women’s brain enables them to switch better from one task to another task and it explains the reason why women are better in tasks that involve both logical and intuitive thinking. This is why women are better than men at remembering faces.

single-focus-multitasking

On the other hand, in men connections lie within a hemisphere that allow them to concentrate on things that don’t need complex combination from both hemispheres which results in one-track thinking. In addition, the higher connectivity between hemispheres in cerebellum of men gives them better motor skills than women. This is why men are usually better at learning how to swim or parking a car.

The more interesting fact is that the researchers also found that the brains of boys and girls aged 8-13 showed only a few differences, which later became more pronounced in adolescent years. In other words, these variations are not congenital and we are not born this way. Unfortunately, the reason is still unknown, but American government has recently promised to spend a good amount of money for brain research through Advancing Innovative Neurotechnologies. The advancement of techniques depends on the development of ways to look into living brains so that better results can be shown.
