Dr David Sinclair is a professor of genetics at Harvard, a co-director of the Paul F Glenn Centre for Biology of Aging Research, and an author. His research and biotech companies focus on understanding why we age and how to slow its effects.

Dr David Sinclair's introduction

The new idea of ageing is that it’s not just random stuff in your body going wrong. There’s actually a program that starts at birth. The Horvath clock or epigenetic clock is the biological clock that is ticking all the time. The clock is measured by the methylation of the DNA. A chemical called methyl is added to the DNA and it stays there and ensures that cells have their identity and play the right genes for the rest of your life.  What you do in your 20s and 30s will impact how healthy you are in your 70s, 80s, and 90. There are ways to work on ageing that can keep the whole body young.

Why we age

The brain age ages slower than the rest of the body. The brain has super protective mechanisms that keep the brain younger for longer.  After the age of 40, the volume of the brain reduces about 5% per decade. However, you can slow that process down and even reverse it later in life.

The brain ages different to the body

<ul><li>mTOR, responds to low amounts of amino acids, particularly leucine, isoleucine, valine.</li><li>AMPK pathway. AMPK senses low energy, low glucose levels, and makes more energy, more mitochondria, boost NAD.</li><li>Sirtuins. The sirtuins require a fuel called NAD that can be activated by certain chemicals. As we age, we make less NAD and burn more of t.</li></ul>All three factors work together to protect the body. They turn up metabolism, burn fat, repair DNA, remove senescent cells, they lower inflammation.

Three main longevity factors that respond to adversity

While your body clock is ticking away, the loops and bundles of the DNA are getting messed up. When a cell is overstressed and damaged, the sirtuins have two jobs:<ol><li>They have to make bundles of DNA and ensure the cell has its identity. When the chromosomes break or you crush a cell, the sirtuins rush in to help repair the broken DNA.</li><li>Sirtuins then have to reestablish that structure. They can put back 99.9% of those structures to how they were. But that .1% never goes back and accumulates over time. That is called ageing. </li></ol> To mitigate that, we need to upregulate the sirtuins through NAD boosters.

The role of sirtuins when it comes to ageing in the brain

All three pathways play a role in autophagy (cleaning out damaged cells), but mTOR is the most potent. mTOR responds to insulin signalling and fasting. In response, it mobilises proteins to be recycled and made into new proteins when you’re hungry.  When we get older, we have misfiled proteins: In the eye, they’re called lipofuscin. In Alzheimer's, they’re plaques and tangles of proteins. To get rid of them, you need deep cleansing called chaperone-mediated autophagy.Changing our diet ensures all three pathways are working.

Autophagy

A good Mediterranean-type diet protects the brain from ageing and can even reverse aspects of ageing in the elderly. A Mediterranean diet includes olive oil in the diet, red wine, and very little red meat.<ul><li>Red wine has polyphenols that directly activate SIRT1.</li><li>Olive oil has oleic acid, which is also found in avocados and can also directly activate the enzyme.</li><li>Low levels of protein and a plant-based diet.</li></ul> The Mediterranean diet mimics adversity. Your body has to work a bit harder to get everything it needs.  Aerobic exercise and walking improve cognition, particularly as we age.

Diet and Exercise

<ul><li>If you eat a plant-based diet, supplement with vitB12, B6 and B3. These B vitamins ensure you have the methyls that control the DNA methylation clock.</li><li>Low levels of B12 can cause deficiency and errors in DNA methylation and can accelerate heart disease and dementia.</li><li>Omega-3s are building blocks of the brain. If you don't eat enough fish, consider supplementing to achieve proper ratios of omega-3: EPA:DHA.</li><li>The brain needs fat to protect the brain from inflammation and damage.</li></ul>

B vitamins and omega 3s

<ul><li>High blood sugar is bad for brain activity and leads to dysfunction in all tissue.</li><li>Metformin has had good success in improving brain health.</li><li>Taking 250mg of nicotinamide riboside (NR) daily will likely increase NAD and decrease inflammation.</li><li>Nicotinamide mononucleotide (NMN) seems to be more effective than NR at improving vascular tissue</li></ul>

The Science of Keeping the Brain Healthy | Episode 7

Marie Curie profoundly impacted the world. Born in 1867 in Warsaw, Poland, she was a child prodigy in literature and mathematics. She worked as a governess until age 24 to save money for school and became the first woman in France to earn her PhD. She studied uranium, which was not well understood at the time. She discovered two new elements, radium and polonium, created cancer treatments and advanced x-ray technology, won a Nobel Prize in 1903, and won a second Nobel Prize in 1911.

Learning from Marie Curie

As an extraordinary scientist, Marie Curie relied on three key strategies to understand the world, make decisions, collaborate with others, and explore new ideas. <ul><li>She embraced the unknown. Curie challenged widely-held beliefs and later proved her position.</li><li>Making radical bets on herself. When Pierre Curie, her husband and lab partner, unexpectedly died, she did not step down from the lab as colleagues expected but stayed at the university, Sorbonne, and took over the lab herself.</li><li>Sharing her ideas. Marie Curie would work with anyone interested in radiation, including people in healthcare.</li></ul>

Marie Curie’s thinking strategies

<ul><li>Learn how to bet on yourself. Marie Curie made decisions about her career because she valued science. What small risk can you take right now to improve your work or life?</li><li>She made choices based on her values. Are your work and personal decisions aligned with your values?</li><li>Share ideas. Use them to connect with others inside and outside your field. It will give you the opportunity to receive feedback.</li></ul>

How to think like Marie Curie

Marie Curie became the first woman to win a Nobel Prize in 1903. Then, in 1911, she became the first person to win two Nobel Prizes, and still holds the record as the only woman who has earned two Nobel Prizes in two different fields.

Marie Curie: the power of sharing radical ideas with the world

When there is an accident at a nuclear power plant — if there's an explosion or a leak or it's damaged in some way in war — radioactive iodine is one of the first substances that's released into the atmosphere.If that radioactive iodine gets into the body, it can damage cells in the thyroid and result in cancer.You can inhale radiation, or it can get into your body via the skin. But you can't see, smell or taste it in the air. It's an invisible threat.

Radioactive iodine

<ul><li>Our bodies do not produce iodine themselves. But we do need it, so we consume iodine through food or supplements.</li><li>When consumed, the iodine is collected or stored in the thyroid gland, where it is used to produce hormones. They help various bodily functions and even support the development of the brain.</li><li>The thyroid can, however, become saturated with iodine. And when that happens it can't store anymore.</li><li>The theory is that if you take enough "good" iodine, there will be no room left in the thyroid for any "bad" or radioactive iodine. That radioactive iodine should then simply pass through the body<warningtag> and get excreted via the kidneys.</warningtag></li></ul>

Is it worth taking iodine against radiation?

There is no point in taking iodine as a precautionary measure to prevent against radiation exposure after a leak or attack on a nuclear power plant.The thyroid only stores iodine for a limited amount of time. And taking too much iodine — even the good stuff — can be dangerous.But the iodine is still only effective if taken when it is needed. Experts say an iodine "block" only has a chance of helping if the good iodine is taken just before or during contact with radioactive iodine.

Don't take iodine as a precaution

Fears have grown about radiation exposure since Russia's attack on a Ukrainian nuclear facility. But taking iodine won't always help. It can, in fact, be dangerous.

How Many Solar System Are There In The Milky-Way? #shorts

With plans to put humans on Mars in the near future, a medical emergency beyond the stars could spell disaster. Nina Louise Purvis looks at how to fix this problemEarlier this year, it was reported that an astronaut in <a href="https://www.independent.co.uk/topic/Space">space </a>had developed a potentially life-threatening blood clot in the neck. This was successfully treated with medication by doctors on Earth, avoiding surgery.But given that space agencies and private spaceflight companies have committed to landing humans on <a href="https://www.independent.co.uk/topic/Mars">Mars </a>in the coming decades, we may not be so lucky next time.

Background

Surgical emergencies are in fact one of the main challenges when it comes to human space travel. But over the last few years, space medicine researchers have come up with a number of ideas that could help, from surgical robots to <a href="https://www.independent.co.uk/topic/3d-printers">3D printers</a>.

One of the Main Challenges to Space Travel

Mars is a whopping 33.9 million miles away from Earth, when closest. In comparison, the <a href="https://www.independent.co.uk/topic/international-space-station">International Space Agency </a>(ISS) orbits just 248 miles above Earth.For surgical emergencies on the ISS, the procedure is to stabilise the patient and transport them back to Earth, aided by telecommunication in real time.This won’t work on Mars missions, where evacuation would take months or years, and there may be a latency in communications of over twenty minutes.

Surgeries in Mars?

As well as distance, the extreme environment faced during transit to and on Mars includes<ul><li>microgravity</li><li>high radiation levels and</li><li>an enclosed pressurised cabin or suit.</li></ul>This is tough on astronauts’ bodies and takes time getting used to.We already know that space travel changes astronauts’ cells, blood pressure regulation and heart performance. It also affects the body’s fluid distribution and weakens its bones and muscles. Space travellers may also develop infections more easily.So in terms of fitness for surgery, an injured or unwell astronaut will be already at a physiological disadvantage.

Extreme Environments, Not Only a Distance Issue

But how likely is it that an astronaut will actually need surgery?For a crew of seven people, researchers estimate that there will be an average of one surgical emergency every 2.4 years during a Mars mission.The main causes include injury, appendicitis, gallbladder inflammation or cancer. Astronauts are screened extensively when they are selected, but surgical emergencies can occur in healthy people and may be exacerbated in the extreme environment of space.

How Likely Is It To Need Surgeries in Space?

Surgery in microgravity is possible and has already been carried out, albeit not on humans yet.For example, astronauts have managed to repair rat tails and perform laparoscopy – a minimally invasive surgical procedure used to examine and repair the organs inside the abdomen – on animals, while in microgravity.Surgery by a robot controlled from another lab was successfully used to remove a fake gallbladder and kidney stone from a fake bodyThese surgeries have led to new innovations and improvements such as magnetising surgical tools so they stick to the table, and restraining the “surgeonaut”.

It Has Worked Before...

One problem was that, during open surgery, the intestines would float around, obscuring the view of the surgical field. To deal with this, space travellers should opt for minimally invasive surgical techniques, such as keyhole surgery, ideally occurring within patients’ internal cavities through small incisions using a camera and instruments.A laparoscopy was recently carried out on fake abdomens during a parabolic “zero-gravity” flight, with surgeons successfully stemming traumatic bleeding. But they warned that it would be psychologically hard to carry out such a procedure on a crewmate.

The Obvious Issue

Bodily fluids will also behave differently in space and on Mars. The blood in our veins may stick to instruments due to surface tension. Floating droplets may form streams that could restrict the surgeon’s view- not ideal. The circulating air of an enclosed cabin may also be an infection risk. Surgical bubbles and blood-repelling surgical tools could be the solution.Researchers have already developed + tested various surgical enclosures in microgravity environments. E.g. <a href="https://www.independent.co.uk/topic/Nasa">NASA </a>assessed a closed system comprising a surgical clear plastic overhead canopy with arm ports, to prevent contamination.

Bodily Fluids Behave Differently in  Space

When orbiting or settled on Mars, however, we would ideally need a hypothetical “traumapod”, with radiation shielding, surgical robots, advanced life support and restraints.This would be a dedicated module with filtered air supply and a computer to aid in diagnosis and treatment.

The Surgical Environment

The surgeries carried out in space so far have revealed that a large amount of support equipment is essential. This is a luxury the crew may not have on a virgin voyage to Mars.You cannot take much equipment on a rocket. It has therefore been suggested that a 3D printer could use materials from Mars itself to develop surgical tools.Tools that have been 3D printed have been successfully tested by crew with no prior surgical experience, performing a task similar to surgery simply by cutting and suturing materials (rather than a body). There was no substantial difference in time to completion.

Using 3D Printers

Robotic surgery is another option that has been used routinely on Earth and tested for planetary excursions.During Neemo 7, a series of missions in the underwater habitat Aquarius in Florida Keys by Nasa, surgery by a robot controlled from another lab was successfully used to remove a fake gallbladder and kidney stone from a fake body.However, the lag in communications in space will make remote control a problem. Ideally, surgical robots would need to be autonomous.

Robotics Surgery

There is a wealth of research and preparation for the possible event of a surgical emergency during a Mars mission, but there are many unknowns, especially when it comes to diagnostics and anaesthesia. Ultimately, prevention is better than surgery. So selecting healthy crew and developing the engineering solutions needed to protect them will be crucial.Nina Louise Purvis is a postgraduate researcher in space medicine and a medical student at King’s College London. This article first appeared on The Conversation.

Conclusion

I have been researching about the future of healthcare and how it would change over the coming years with the evolving technologies and the growing population. This context may be way into the future, but it is interesting to consider how space medicine can be possible, as you need more than a rocket to venture out in space!

From Surgical Robots to 3D Printers, This is How to Do Surgery in Space

“Scientists for over 100 years have searched fruitlessly for brain boundaries between thinking, feeling, deciding, remembering, moving and other everyday experiences,” Barrett said. A host of recent neurological studies further confirm that these mental categories “are poor guides for understanding how brains are structured or how they work.”

A brain map with neat borders is not just oversimplified — it’s misleading. 

It’s not that “perception” or “memory” is a useless term, he emphasized. But “if we want to understand what the brain does, we probably need much more precise ways to understand particular functions.”

Familiar categories of mental functions such as perception, memory and attention reflect our experience of ourselves, but they are misleading about how the…

Nobody knows for certain how big the Universe is because we cannot see to the edge of it. We don't even know if it has an edge. We can only see out to a distance of about 14 billion light years from Earth. This means that the size of the Universe that we can see is about 28 billion light years in diameter (across). However this distance is determined from things we can measure and infer their distance near at the time of the Big Bang.

The greatest ability of the human brain is to imagine, to see the world as it has never been before.But imagination has three shortcomings:<ul><li>Imagination tends to add and remove details, but people do not realize that key details may be fabricated or missing from the imagined scenario. </li><li>Imagined futures (and pasts) are more like the present than they actually will be (or were).</li><li>Imagination fails to realize that things will feel different once they actually happen—most notably, the psychological immune system will make bad things feel not so bad as they are imagined to feel.</li></ul>

Our Ability To Imagine

The word happiness is used to refer to three related things:<ul><li>Emotional happiness</li><li>Moral happiness</li><li>Judgemental happiness</li></ul>It’s hard to define emotional happiness, but when we feel it, we have no doubt about its reality and importance. Because we have a poor recollection of our experiences, we cannot objectively compare a previous state of happiness to a present state.

About Happiness

All claims of happiness are subjective. And are formed from the perspective of a single human being whose unique collection of past experiences serves as context.Nobody really knows what happiness feels like for others, so that means we can’t say definitely whether someone in a situation that might seem bad to us is actually less happy than we are. In fact, it’s entirely possible they are just as happy or even more so.Not knowing what we are missing is the very thing that allows us to be happy despite not having some other opportunity.

Happiness Is Subjective

Your experiential background can dramatically change your happiness levels. Once you know something exists and have experienced pleasure from it, then your definition of happiness changes compared to what it was in the past.

The Experience-Stretching Hypothesis

Negative events affect us but not as long as we expect them. When our psychological immune system is working, we are able to cope with any negative situation that comes our way. Explaining events robs them of their emotional impact because it makes the event seem more likely. This allows us to stop thinking about them.

Rationalization

Wealth increases people’s happiness after it removes them from poverty and places them in the middle class. After that, there is little relation between wealth and happiness.

Wealth And Happiness

Experience and awareness are closely related but not the same. <ul><li>Experience refers to partaking in an event. </li><li>Awareness refers to being cognizant that the event is happening.</li></ul>

Experience And Awareness 

It happens when a phenomenon arises from very large numbers of something, but not smaller versions of it. For example, billions of neurons lead to a conscious human brain, but two neurons are not a small version of consciousness.

The Law of Large Numbers

Psychological sciences will always be imperfect because we are trying to observe someone else's subjective experience, but it's the best we've got and the closest an outside observer can get to understanding the inside of someone else's mind.

The Shortcomings of Psychology

It refers to judging historical events or people by modern-day standards. It is largely useless and unfair because you can't expect historical figures to make the same decisions as we do now because they lived in a very different context.

How to Be Happy

A smart and funny book by a prominent Harvard psychologist, which uses groundbreaking research and (often hilarious) anecdotes to show us why we’re so lousy at predicting what will make us happy – and what we can do about it. Most of us spend our lives steering ourselves toward the best of all possible futures, only to find that tomorrow rarely turns out as we had expected. Why? As Harvard psychologist Daniel Gilbert explains, when people try to imagine what the future will hold, they make some basic and consistent mistakes. Just as memory plays tricks on us when we try to look backward in time, so does imagination play tricks when we try to look forward. Using cutting-edge research, much of it original, Gilbert shakes, cajoles, persuades, tricks and jokes us into accepting the fact that happiness is not really what or where we thought it was. Among the unexpected questions he poses: Why are conjoined twins no less happy than the general population? When you go out to eat, is it better to order your favourite dish every time, or to try something new? If Ingrid Bergman hadn’t gotten on the plane at the end of Casablanca, would she and Bogey have been better off? Smart, witty, accessible and laugh-out-loud funny, Stumbling on Happiness brilliantly describes all that science has to tell us about the uniquely human ability to envision the future, and how likely we are to enjoy it when we get there.

Understand yourself and those around you.

Stumbling on Happiness

For many different people across the world, Music is one of the most integral parts of their day, myself included.Even as I am creating this, I have music playing in the background. Using observation, are we able to find convincing evidence that Music helps us focus and study more effectively?

Does Music Help You Study Better?

Before delving into the specifics, there are two general ideas to keep in the back of your head while we progress:<ol><li>Different types of music can have varying effects on study patterns (classical music effects differ from lyrical music effects).</li><li>Different songs, and subsequently different lyrics, can also affect studying patterns (if a lyric was very deep, it invokes a specific thought which could distract you from studying).</li></ol>

Background Information

In general, listening to Music has a plethora of different, positive effects on the human body. Some of these positive effects include:<ol><li>Reduction in stress</li><li>Alleviation of depression symptoms</li><li>Increases workout endurance</li><li>Elevation of Mood</li><li>Stimulation of Memories</li></ol>

The Positives of Music

Now for the main question: Does Music really help us study better? Yes and no.Music, depending on what it is that you are studying, can either help you or restrict you. For example, if you are trying to memorize certain terms for a biology class, having music in the background can be very helpful.However, if you were reading a novel or trying to interpret a specific text, having music in the background can end up being more of a distraction than a tool for success.

Effectiveness During Study

<ol><li>In 2011, there was a study regarding the effectiveness of background music that was performed with ADHD Students.</li></ol>The study revealed that although there were a couple of people that got distracted, the majority of the classroom was able to improve as a result of there being background music.<ol><li>In 2014, a study was conducted on young adults to measure whether classical music was able to help them perform better on memory-based tasks. </li></ol>The study did in fact reveal that by listening to classical music, there was a significant improvement in performance on these memory-based tasks.

Convincing Evidence?

Circling back to the Background Information, it should be noted that although music is seen to improve studying for groups of people OVERALL, that does not mean that it will help every single person.This means that you should try it for yourself! If you are able to focus on your work more easily as a result of background music playing in the background, then do it! Otherwise, make sure to create the most optimal work environment for yourself.However, with the majority in mind, there is convincing evidence to show that Music does help you study better.

Music is one of the most common necessities that many people would struggle to go without in their lives. The question we are exploring today is whether or not listening to Music helps study better.

You might have heard music improves concentration, but it’s not that simple. There are ways music and studying can work together, and some ways they can’t.
