What is the Possibility of Living On The Neighbouring Planet: Mars

Since 2012 when NASA landed the Mars Exploration Rover the whole nation questions whether or not the planet next to us is capable of supporting life. If our planet ever comes to a dooms day or judgement, knowing that there is a life-sustainable planet right next to us can help ease the anxiety created by the fear that the world can come to an end. Based on all the recent articles released by the press it seems as though scientists are hinting us that Mars is habitable.

Personally I enjoy believing that Mars is a planet human can “run to” as a second home when Earth cannot support a total population of eight million people that is increasing at an exponentially rate. Let’s face it the Earth is getting over populated with all of its resources getting depleted and trained to the very bits. One of the sources that allow Earth to be sustainable is the almighty Sun that radiates its solar energy on our planet’s surface, making it possible for primary gases like carbon dioxide and ozone to form and produce a habitable atmosphere. Recently researchers hypothesized that in approximately two billion years the heat radiated from our Sun may make it possible for Mars to become habitable. Years later when the heat emitted from the sun is in a perfect temperature range, enough to boil carbon dioxide (CO2) and produce an atmosphere sustainable to life.

Another possibility comes from the analysis of the oldest minerals discovered by the Mars Rover show that billions of years ago Mars had liquid water that could lead to liveable planet. For now the temperature on Mars is still too cold for liquid water to be produced and provide support needed for life. If water every formed on Mars there must have been livable mud that existed on the planet. Chances are that if Mars had once had the ability to produce liquid water and sustainable mud then in future years it is possible for our neighbouring planet to do it again.

Below is a question&answer video from Dr. Emily Rice who speaks about whether heat from our Sun make Mars habitable

Even if these ideas are only possible billion of years later, the hint that researchers been trying to tell us is that Mars will eventually be a habitable planet. The question is whether the history of human race will survive long enough and develop state of the art technology that can transfer a great number of lives to Mars.

Are Europe and North America Losing the Battle for Science Supremacy?

For centuries, Western Europe and North America have resided at the centre of innovation, research, and scientific advancement. Starting with the Scientific Revolution, which saw the advancement of modern science, the major European countries began to assert their prowess in the intellectual arena. Jumping ahead, up through the age of Imperialism and into the Industrial Revolution of the mid-18th and 19th centuries, the United Kingdom emerged as the clear leader in scholarship and technological innovation. Beginning in the 19th century, the United states moves to the forefront of global scientific efforts; a place it arguably holds even today. Despite the storied history of western dominance of science in the modern age, recent research suggests a swing in the balance of power may be under way.

 Several recent articles in Nature News & Comment have reported that, over the last decade, China has slowly maneuvered its way to the top.  Specifically, China is now the world’s third-largest producer of scientific research articles and has nearly tripled the percentage of its gross domestic product (GDP) it invests in science and innovation. Even as the combined productivity of the European Union and US has declined, China’s own output has climbed from 3% to 11% since 2001. Furthermore, at 1.98% GDP investment in research and development in 2012, China has officially surpassed Europe and now places third, behind the US and Japan. Interestingly, while European investments remain relatively stagnant, China is set to increase to 2.5% GDP investment in R&D by 2020. No matter how one looks at it, China, and many other parts of Asia, are rapidly becoming global competitors in the race for science supremacy.

Perhaps more worrying that China’s rise in the ranks of international funding and scientific innovation and publishing, is the widespread decline of education is mathematics and science in western countries. The Paris-based Organisation for Economic Co-operation and Development (OECD), an association of 34 member countries aimed at aligning domestic and international policies, administers a test to assess the success of each countries teaching in mathematics, reading, and science. The Programme for International Student Assessment (PISA) is administered to 15-year-old students every three years, and is meant as a comprehensive performance review of education policies. Once the dominant contestants for the top 10 overall educational results, the 2012 PISA results show that western countries have rapidly fallen behind Asian constituents, with the US scoring below the OECD average in all three categories of interest.

So has the time of western-led scientific advancement come to an end? Probably not. Although the current numbers show that the the EU and North America are lagging, the US has retained its position as the number one country for research and development and foreign direct investment. Furthermore, while China’s %GDP investment in research and innovation has surpassed that of the European Union, the total dollar-amount investment made by the EU still remains higher. Additionally, the same article discussing China’s recent growth in research out-put also noted that the US remains the leading producer of highly cited literature, whereas Chinese-published material is largely cited within China alone, and argues that this may be a case of quantity over quality. Lastly, international research collaboration and ‘big science’ is at an all time high, suggesting that while each country is  facing its own challenges, collaboration may allow for sharing of the burden.

Empowering Autonomy in Scientific Education

When you think about undergraduate education, what do you visualize? In my mind, I picture large lecture halls filled with many students sitting shoulder-to-shoulder, in the fold-down chairs with the fold-up tables. At the front of the room, the professor lectures away while students quietly take notes for an upcoming exam. Sounds familiar, doesn’t it?

Don’t get me wrong- I’m not suggesting that lectures are unacceptable or a waste of time. Certainly, lectures has its place at large universities such as UBC. In fact, I think lectures are great because it allows many students to learn from incredibly knowledgeable professors. I will argue, however, that this should not be all there is. There needs to be more opportunities for student-centered learning, especially in science where discoveries depend on creativity, critical thinking and effective communication rather than passive accumulation of information.

Carl Rogers describes student-centered learning as a shift in power from the expert teacher to the student learner. Lea et al. (2003) emphasizes the importance of active learning where participation and involvement is essential for quality education. In recent years, the term student-centered learning has been increasingly used, along with flexible learning, experiential learning and self directed learning. The emergence of this proactive approach in education reflects today’s society where choice and democracy are important concepts.

But the fact that active learning is good is not breaking news. Rather, it’s quite obvious! So what’s the big deal anyway? The big deal is that “many institutions or educators claim to be putting student-centered learning into practice, but in reality they are not (Lea et al., 2003).” However, I do believe that UBC is indeed an advocate for student-centered learning.

This semester, as part of the UBC student directed seminars program, I am leading a course on the topic of traumatic brain injury. The UBC student directed seminars program allows undergraduate students to create their own 3-credit course for a 15 person maximum class. As I have strong interests in neuropsychology, I created a course that explores in depth how a traumatic brain injury can profoundly impact an individual’s life. From project conception to execution, UBC has provided me with all the resources, guidance and support I need to succeed.

The experience leading a seminar so far has taught me a lot regarding how to effectively communicate science. Our motto here at UBC is “Tuum Est” which means “make it yours”. Our undergraduate careers are too short (and expensive) to spend passively learning what we’re told. There are ways to personalize the experience of how we learn about science whether it’s through a hands-on research project, a student directed seminar or even service in the community. It’s important to find your passion, but it’s also important to then pursue that passion from different facets outside the traditional lecture.

A Positive New Outlook on Brain Activity and Aging

Aging comes with many worries, often related to health scares and a fear of cognitive decline. From personal experience, I know that even in our early twenties we’re told that our mental prowess has already diminished.   However a new study by Ramscar et al (2014) gives hope to those worried about their aging minds!

In the past, studies have shown that memory not only deteriorates with time, but that the decline begins as early as 45 years old.

With continual medical advances, people are living longer and the average life expectancy in Canada is now 81 years old. This means that research into how brain activity and memory are affected with age is becoming extremely important in our society. Personally, I know that I would like to be able to keep up to date with modern scientific developments, and maybe even learn a third or fourth language when I’m well into my 60’s and 70’s.

Ramscar’s study takes a different approach to memory than previous works, stating that old models for memory degradation “do not take account of the statistical skew  of human experience or the way knowledge increases with experience. As a consequence… [this] paint[s] a misleading picture of cognitive development.” His model/study instead shows that older adults appear to have a worse memory simply because they need to process through more information before finding an answer, causing their responses to be slower. The study also accounts for the fact that fine-detail memory differs with age and makes the claim that older populations “encode less contextual information”, simply because throughout their lives they learn to ignore what they think is useless background information.

I found this study to be extremely exciting and relevant, since the world’s population is becoming more and more top heavy (larger old population then young population). With studies like this, it becomes clear that research on cognitive diseases is extremely important since cognitive abilities remain fairly constant throughout our lives in the absence of disease.
