In collaboration with Dr. Aakila Sammy of Publett Last updated: 14/11/24 Published: 08/05/23 On the 25th of May, 2020, the world was shocked by the brutal murder of George Floyd, a black American man, by four white police officers. This led to mass outrage among every creed and race and propelled the Black Lives Matter movement to new heights, even in places like Palestine, a country already drowning in peril. While his last words were “I can’t breathe”, the transcripts revealed that he repeated several times, "Momma, I love you. Tell my kids I love them. I'm dead." As painful as it is to hear these words, especially for his mom, it's not surprising; calling out for your mom when death approaches. Many hospice nurses and soldiers recall that dying men call out for their “Mommy” or “Mama” in their last breath. Some have attributed it to its caregiver familiarity, primal instinct like calling out for your mom as a child or a Mary-Jesus connection. George Floyd (1973-2020). Image/ Publett We know that “the mother” is largely responsible for every life on earth, and most of them have the ability to make everything better, but what if that connection is more than something psychological or spiritual? I know, a physical connection to your mom outside the nine months of her carrying you? Like at this moment? Yes! Scientists call it micro-chimerism, and it may be able to explain why for most, the next greatest pain to losing a child is losing your mom. Micro-chimerism originates from the Greek mythical creature “Chimera”, a monster made up of three animals; a lion, a snake and a goat. In medicine, micro-chimerism was initially described as “alien cells”, and it is simply the circulation of cells from one individual in another genetically distinct individual. A Greek 'Chimera'. Image/ Publett And the culprit? There are several actually; natural cases like pregnancy and breast-feeding and artificial instances like organ or blood transplant. And it goes both ways! It could be responsible for that gut feeling you get when something is wrong with your child, also known as “a mother’s intuition”. And it doesn’t stop there; it has been observed in multiplet pregnancies like twins, which may be why twins have their own intuitive connection. So, in addition to nutrients and waste being exchanged, cells are also trafficked bi-directionally. The embryo/fetus receives cells from the mother and the mother from the fetus, and everyone coexists peacefully, sometimes spanning decades. And the burning question that might be in your mind right now is whether a biological female can have male DNA circulating in her body after carrying a male baby. Yes! Cells are also trafficked bidirectionally. Image/ Publett But what are the limits to this phenomenon? This answer is not clear-cut and varies among individuals and situations. Scientists have found maternal-fetal micro-chimerism is present as early as the embryo stage, and the further along, the more abundant it is. This allows non-invasive tests for genetic abnormalities or gender determination on the fetus using blood drawn from the mother. Another situation where it varies is trauma. We might all be familiar with the fetus releasing stem cells into the mother's circulation, which comes with healing benefits to maintain the well-being of the fetal host – and these cells can be detected up to 27 years after delivery. Even though they sound insignificant, fetal cells aren’t afraid of a challenge. Researchers have found them taking on the role of cancer immune surveillance, clustering around lung tumours in women decades after pregnancy and reducing risk of ovarian cancer in women who have later pregnancies. Now, in the case of abortions and miscarriages, the phenomenon might come as a source of comfort, heartache or both. It is unclear how early fetal cells enter the mother’s circulation; it can be when the placenta attaches around week eight or earlier. Commercial fetal blood tests start at weeks 7-8, but this is when they are abundant enough for testing, so it might very well be earlier. So, what does it mean if you have a miscarriage or abortion before week 8? No fetal cell acquisitions? On the contrary, the trauma of the process, especially in the first trimester, causes a massive acquisition of fetal cells by the mother. It is higher in the case of abortion and even higher in surgical abortions versus chemical abortions. Although the fetus is described as having parasitic nature, this last farewell release of healing benefits to its host is nothing short of pure. While controversy still exists around the role of maternal and fetal microchimeric cells, we still crave answers to questions like: How is the phenomenon affected when the fetus carries genetic abnormalities? Do fetal cells from a previous pregnancy enter the circulation of the fetus sibling in a subsequent pregnancy? It might also result in psychologists reframing questions they ask their male patients; are they worried about becoming your father, or should they be more concerned about becoming their mothers? Plus, we need more on the association between parous women and autoimmune diseases, especially in fetal Y-chromosome carriers. Micro-chimerism is a promising and exciting area of research with much to reveal for many fields. While no concrete evidence exists, we know that these cells are resilient to stress and trauma and offer a new perspective to inter-individual bonds and intuitions. Many scientists believe that individuals are calling out to these cells in times of survival, and maybe that’s why kids call out to their moms first or men their mothers near death. -- Scientia News wholeheartedly thanks Aakila Sammy , co-founder and CEO of Publett , for this fascinating piece of work on a lesser-known genetics topic of micro-chimerism.

Common questions and answers- along with helpful resources- regarding the International Baccalaureate programme. International Baccalaureate (IB) Are you a student currently studying the IB Diploma Programme (IBDP), or about to commence it? You're in the right place! You may also like: A-level resources , University prep and Extra resources What is the IB? Jump to resources The IB is an International Academic Program which is another alternative to A levels. This is a highly academic program with final exams that prepare students for university and careers. You select one subject from each of the five categories, which include two languages, social sciences, experimental sciences, and mathematics. You must also choose either an arts subject from the sixth group or another from the first to fifth groups. How is the IB graded? Subjects might differ from schools and countries but these are the ideal subjects given in the IB. IB is graded through a point system (7 being the highest and 1 being the lowest) and the highest mark you can achieve in total is 45. For the 6 subjects you study you can achieve a maximum of 42 points. Theory of Knowledge and Extended Essay are combined to gain 3 extra bonus points. These 2 subjects will be marked from A (highest) to E (lowest) and then will be converted to points. What are the benefits of studying the IB? Even though there are a lot of subjects, this programme is great for students to gain new skills and be an all- rounder. IB also helps students to have a better idea of how work will be in university especially with coursework and that is one of the main things you will work on when studying IB- it is known as Internal Asssessment (IA). Doing CAS is also a great opportunity for students to be independent and find activities/ services to do outside of school to build up their portfolio on CAS as well as their CV/ personal statement when applying for university. The marking matrix used in the IB. How do universities use the IB to select students? All universities around the world accept the IB as a qualification gained in secondary school. Depending on the degree you are applying to, universities mainly focus on your Higher Level (HL) subjects. Each university has their own requirements for students applying to study a course at their institution. The most common way is considering your total point score out of 45, and your total point score of your HL subjects. Another way is asking applicants to achieve a certain grade in a particular grade at HL or at standard level (SL). If you complete the IB programme well enough, universities may prefer you over the other qualifications e.g. A-levels. Benefits of completing the IB programme.

- And face masks! No need to say they don’t work either. No matter the number of layers in the mask. Nothing is ever 100% efficient, and face masks are not exempt from this. Face masks help a lot by stopping you from inhaling COVID-19 particles in the air, indeed spread by people not wearing, or cannot wear, masks. Not just COVID-19 particles, Go back Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link Misconceptions about COVID-19 and its vaccine Last updated: 07/11/24 Published: 28/12/22 Three years into the pandemic, after huge losses in lives, livelihoods, and freedoms, misinformation about the coronavirus and now its vaccines, are still in circulation on the internet. It will take time to completely eradicate these misconstructions, but it is not impossible. I will begin discussing some myths and theories about the coronavirus itself, and then continue on to the vaccines science has developed to battle the virus. The misunderstandings are not listed in any order. Coronavirus The virus is called many different names: coronavirus, SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2). The disease it causes is called COVID-19, or simply COVID. – Getting COVID is no big deal. It is just another flu. It is true yes that COVID-19 is only a mild condition for most people, however for those who are elderly and/ or clinically vulnerable it is anything but mild. Getting COVID-19 depends on the immune system, and if the immune system is already weakened, it is a big deal. As for the flu, it has been around for years mutating each time, but it is never less of a threat. – Only the elderly contract it. In most cases, it is the elderly who fall victim to the disease. But there are many factors at play; age is only one of them. Pre-existing health conditions regardless of age (for those clinically vulnerable), ethnicity, wealth, gender (does not factor that much), all determine who contracts it and how long it will take for someone to recover from the disease. – Children and teenagers are immune to it. Not necessarily true. For the better part of a year, children and younger adults seemed to evade COVID-19 but now more and more are falling ill to it. It is probably due to the emerging variants and how vulnerable children are. – Herd immunity is the way out. We do this by sacrificing said elderly to save the economy. It would have been the ideal solution to continue working and travelling while the virus ravages entire nations to protect the economy, but it would also have meant exposing society’s most vulnerable, namely the elderly, to the virus. Not a good solution to only protect one generation of society and not another. – Yes, because lockdowns don’t work. Lockdowns tend to have a rapid effect; they act to break the circuit of virus transmission up and down the country. They work. This is the reason why they last no more than one month or so when put in place. However, lockdown costs people’s freedoms and mental health so it should only be imposed when crucial. – But we need to work! How will we support ourselves? Very understandable. But if you suddenly contract COVID, you will not be able to work anyway. Many government initiatives have been started to support workers in the past year or so. - What is this 2m/ 6ft rule? No social contact whatsoever? The particles don’t even travel that far. The major way coronavirus travels is by droplets in the air between human contact. Not through surfaces (very little evidence supporting this), not by sharing needles, not by parasites and animals (vectors that bring the virus to humans). - And face masks! No need to say they don’t work either. No matter the number of layers in the mask. Nothing is ever 100% efficient, and face masks are not exempt from this. Face masks help a lot by stopping you from inhaling COVID-19 particles in the air, indeed spread by people not wearing, or cannot wear, masks. Not just COVID-19 particles, but any other harmful particles. You’re still able to take oxygen in and carbon dioxide out- these molecules are much smaller, 1-3 atoms big, so they can pass through the mask. Multiple layers of the mask offer more protection, however one is enough. - Antibiotics can be used to treat COVID-19. Antibiotics are anti-bacteria. Coronavirus is a virus- only antivirals will help. - Surely if bleach cleans and wipes out pathogens on surfaces and on just about anything else, it can do the same inside our bodies. Bleach is for surfaces only; they are not for consumption or administration as medicine. They will cause untold amount of damage inside the body. Bleach also turns things white. Whatever cleaning and wiping of pathogen need to be done, your immune system will do it. No need for bleach. - How does opening windows help prevent the spread of COVID-19? As mentioned before, COVID-19 respiratory particles travel by air. So opening windows and increasing the circulation of air, helps the particles to be blown away from you and the people with you and reduces the chance of becoming infected with the virus. Going outside for this reason helps (if not under lockdown or other restrictions). - How does fresh air help? As above. Vaccine – I think they will inject a microchip under the pretence of a vaccine and will track my every movement. There is no microchip. All the ingredients and chemicals used to produce the vaccines are available to view on the respective pharmaceutical website. None of the ingredients have any tracking potential. – Or they are just making money. Usually the government or state orders and buys the vaccines from the different companies. The expenses are on them. The rest of the population get the vaccine for free. - Vaccines hurt. Only a pinprick when the vaccine is being administered. After that only mild side effects and taking paracetamol or other painkillers will help. - And we are part of a big experiment. All the testing and experimenting was done during the three phases of clinical trials. The vaccines have been approved for (temporary) nationwide use. - Vaccines don’t work anyway. There is always a story in the news detailing the efficacies of the vaccines. They have an efficiency of 70-96% depending on the vaccine, and vaccine dose. Generally, the benefits of the vaccine far outweigh the risks that come from it. - Yes, because they cause shedding. Check the context and definition of this word. ‘Shedding’ here refers to the vaccine releasing or discharging its viral components onto others and infecting them. Once inside the body, the vaccine has no way to expel the viral contents.The only way the virus will shed its components is when the person is infected and sneezes, coughs, or causes the particles to travel in the air (i.e. when NOT vaccinated). - And, fertility issues. No biological mechanism or pathway has been discovered over the centuries that shows vaccines cause fertility issues. In fact, the reproductive system itself suppresses the immune system (not the other way round). - They will definitely cause issues if given to children. Vaccines were originally produced to provide protection to adults 18 years and older. Though there are vaccines that only children take as routine e.g. MMR (measles, mumps, rubella) and children don’t typically have any problems with them, COVID-19 vaccines aren’t among them. - Vaccines contain meat, and/ or made from animal products (and I am against this). As mentioned already, all the ingredients of the different vaccines can be found on the individual drug company websites. None of the vaccines contain meat, and if religion-conscious, scriptures advise the use of health agents even if they contain meat, to better your well-being. Anyway, the vaccine is used as medicine and not as an item for consumption. – You can pay to get a vaccine made from glucose sugar and water, and I believe it does the same thing as the official vaccine. Sugar solution is not a vaccine. It does not prevent against COVID-19. No trials have been conducted in favour of this. For a vaccine to be a vaccine, it is essential to have the actual weakened version or mRNA form of the virus. - Please take the time to read, watch, or listen to official government or health system information on coronavirus and vaccines. Millions if not billions have listened so far, be a part of this number. As with any public health guidance, education and spreading awareness are always key.

Lyra is a prominent constellation, largely due to Vega which forms one of its corners, and is one of the brightest stars in the sky.

On April 22nd, the shower is predicted to reach its peak, offering skygazers an opportunity to witness up to 20 bright, fast-moving meteors per hour which leave long, fiery trails across the sky, without any specialist equipment. The name Lyrids comes from the constellation Lyra - the lyre, or harp - which is the radiant point of this shower, i.e. the position on the sky from which the paths of the meteors appear to originate. In the Northern Hemisphere Lyra rises above the horizon in the northeast and reaches the zenith (directly overhead) shortly before dawn, making this the optimal time to observe the shower. Lyra is a prominent constellation, largely due to Vega which forms one of its corners, and is one of the brightest stars in the sky. Interestingly, Vega is defined as the zero point of the magnitude scale - a logarithmic system used to measure the brightness of celestial objects. Technically, the brightness of all stars and galaxies are measured relative to Vega! Have you ever wondered why meteor showers occur exactly one year apart and why they always radiate from the same defined point in the sky? The answer lies in the Earth's orbit around the Sun, which takes 365 days. During this time, Earth may encounter streams of debris left by a comet, composed of gas and dust particles that are released when an icy comet approaches the Sun and vaporizes. As the debris particles enter Earth’s atmosphere, they burn up due to friction, creating a streak of light known as a meteor. Meteorites are fragments that make it through the atmosphere to the ground. The reason that the Lyrids meteor shower peaks in mid-late April each year is that the Earth encounters the same debris stream at the point on its orbit corresponding to mid-late April. Comets and their debris trails have very eccentric, but predictable orbits, and the Earth passes through the trail of Comet Thatcher in mid-late April every year. Additionally, Earth’s orbit intersects the trail at approximately the same angle every year, and from the perspective of an observer on Earth, the constellation Lyra most accurately matches up with the radiant point of the meteors when they are mapped onto the canvas of background stars in the night sky. The Lyrids meteor shower peaks in mid-late April each year. Image/ EarthSky.org This year, there is a fortunate alignment of celestial events. New Moon occurs on April 20th, meaning that by the time the Lyrids reach their maximum intensity, the Moon is only 6% illuminated, resulting in darker skies and an increased chance to see this dazzling display.

For more information, please refer to the World Health Organisation (WHO) and the Centers for Disease Control and Prevention (CDC). – A Adenovirus- a group of related viruses. They were first removed from human adenoid glands (found at the back of the throat), hence the name. Asymptomatic- where a person is infected by the virus but does not present any symptoms. Can still pass the virus and infection onto others. C Coronavirus- a group of related viruses that cause diseases in mammals and birds. Named after the crown-like spike protein on the virus’s surface- ‘corona’ in Latin for crown. COVID-19/ COVID – the disease that coronavirus causes D DNA- deoxyribonucleic acid, the cell’s code to life. DNA instructs how to make proteins, which are essential for function in the body. Double helix. E Epicentre- the central point of the virus outbreak. This changed during the COVID-19 pandemic depending on the variant of virus. Epidemic- an outbreak in a localised area at a particular time H Herd immunity- when enough people are protected against the disease, that it lends immunity to those who are not protected. Can achieve protection against the disease through either previous infection, and/ or vaccination. I Immunity- achieving immunity means to be protected from future infections by viruses, and bacteria for example. You can achieve immunity through either previous infection, and/ or vaccination. Immunosuppressed- the immune system is suppressed. In other words, people who are immunosuppressed have a reduced ability to fight diseases. Thus preventing them from being infected in the first place is of great importance. Infection- the unnormal invasion of microorganisms into the body. Some infections present symptoms- at least straight away- while others do not show any symptoms. L Lockdown- preventing people from leaving where they are, to stop the transmission and contain the virus in the COVID-19 pandemic. M Mass vaccination- vaccinating many people in a certain area at a particular time mRNA- messenger RNA (ribonucleic acid). Single helix. Acts as a go-between for DNA and the proteins that are being made. P Pandemic- a global, or national outbreak Protein- an important molecule. Used as a fuel source, a building block, a carrier among other things, in the human body. R Restrictions- impeding or hindering movement and travel during the COVID-19 pandemic, in order to contain the spread of the virus and curb transmission. S Shedding- (in biology) refers to viruses casting off viral particles which can then infect others Side effects- effects that are different and potentially harmful from the main, intended effects of a medication, treatment, or vaccine. Examples of some side effects: headaches, aches, pains, fever. Symptomatic- where a person is infected with the virus and does present symptoms. Can still pass the virus and infection onto others. Symptoms- the signs a person has been infected; this can be physical or mental. With COVID-19, you can show symptoms as symptomatic, or not present symptoms as asymptomatic, if infected. Examples of symptoms for COVID-19 include loss of taste and smell, a persistent cough, fever. T Transmission- how a particular disease, in this case coronavirus, is passed from one person to another. V Vaccination- the administration of vaccine into the body. Vaccine- a form of active immunity, where a weakened, live version of the infection agent is administered into the body. The immune system kicks in and destroys the infection agent, but not before taking note of the genetic material (e.g. mRNA or DNA from the protein) from the agent. The immune system will use this genetic material to ‘remember’ the infection next time it appears, so it can prepare a speedier, more efficient response. Vaccine hesitancy- uncertainty as to whether people should take the vaccine. This could be due to a variety of reasons: being unfamiliar with the vaccine and its contents, and/ or being distrusting of the government and those in the health organisation. Viral load- the amount of virus (or viral genetic material) a person has in their body at a particular time. A person not infected with the virus will have no viral load, whereas a person infected with the virus will have a much higher viral load. Virus- a microorganism. Some spread diseases as vectors, while some are ‘better’. To date, it is being argued whether viruses are alive or not. W Wuhan- Capital of Hubei Province in China. First epicentre of coronavirus.

Launched in 2021, James Webb Space Telescope (JWST) is an astronomical observatory, designed to explore and observe the universe beyond the capabilities of its predecessor, the Hubble telescope. The JWST has primary mirror of 6.5m in diameter, the largest of any space-based telescope, and its advanced infrared technology, it can observe objects that were previously too faint, old, and distant for the Hubble telescope. Go back Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link James Webb Space Telescope: A Breakthrough in Space Exploration Last updated: 13/11/24 Published: 25/03/23 Launched in 2021, James Webb Space Telescope (JWST) is an astronomical observatory, designed to explore and observe the universe beyond the capabilities of its predecessor, the Hubble telescope. The JWST has a primary mirror of 6.5m in diameter, the largest of any space-based telescope; and with its advanced infrared technology, it can observe objects that were previously too faint, old, and distant for the Hubble telescope. The JWST’s aim is to revolutionise the exploration of the cosmos by studying the earliest galaxies and stars, and to detect light from the first objects that were formed in the universe. In its short deployment time, the JWST has already provided us with fascinating new insights and images of the deep space, pushing the boundaries of our understanding of the cosmos. History of James Webb Space Telescope • 1996: Next Generation Space Telescope project first proposed (8m) • 2001: NEXUS Space Telescope, a precursor to the Next Generation Space Telescope, cancelled • 2002: Proposed project renamed James Webb Space Telescope, (mirror size reduced to 6 m) • 2003: Northrop Grumman awarded contract to build telescope • 2007: Memorandum of Understanding signed between NASA and ESA[72] • 2010: Mission Critical Design Review (MCDR) passed • 2011: Proposed cancellation • 2016: Final assembly completed • 2021: Launch Achievements of James Webb Space Telescope In its short deployment, the JWST has been able to provide some exceptional data, ranging from beautiful pictures of galaxies and nebulas, the first of its kind image of an exo planet and details of exo planets atmosphere. Since its launch, scientists have been discovering galaxies far away and older than ever before, the launch of this observatory has truly made a breakthrough in space exploration. Some of its achievements are explained more in detail below: • To begin with, the JWST has been able to capture some of the most breath-taking and beautiful images of nebulae and galaxies, in both visible light and infrared spectrum. The new pictures have changed the way we had observed these subjects, giving us a deeper insight into the formation stars in these nebulae due to its higher resolutions. Some of the most iconic pictures from the JWST so far have been the pictures of the pillars of creation and the southern ring nebula. • Studying exoplanets have always been a challenge for scientists, as due to their size exoplanets are only visible through analysis of dips in luminance of its host star. But for the first time, the JWST using its infrared spectrometer and primary lens, was able to capture an image of an exoplanet directly. • During its observations, the JWST has been able to study and explore many star systems and in some cases, the exoplanets as well- going as far as studying their atmospheres in some detail, giving the research teams an insight into what these worlds may look like. • The JWST, while observing the deep space, has been able to capture the oldest galaxies known to mankind, dated as old as 13.4 billion years, 350 million years after the Big Bang. Future of Space Exploration and JWST The launch of the JWST marks a significant milestone in the field of space exploration. Not only has it opened up a new era of scientific discovery, but it has also introduced a new era for large space structures. The JWST, being the first self-assembling telescope launched in space, has proven that the only viable option for launching such a massive instrument is to make it segmented and assemble it in orbit. As we move forward, the ability to launch large structures in space that can be reassembled will undoubtedly lead to even more significant discoveries. With 6000 hours allocated for different observation missions, the JWST will enable researchers to work towards solving more of the unanswered questions regarding the cosmos. From deep space observation to exoplanet analysis, the possibilities are endless. Written by Zari Syed Related article: Lonar Lake
