Many of us are familiar with hurricanes and the disaster they cause. This last season brought some of the worst storms ever seen, and the trend indicates more will be coming.
Not only should we be concerned with the devastation this will have on the human population, but we must turn our attention to other species as well.
So when you see this video, don’t be so surprised.
Yes, that’s right. For the sole purpose of science, researchers put lizards on a leaf blower and tried to kick them off. Turns out they are pretty good at riding along.
But, why would scientists torture innocent lizards?
Well, they really didn’t. As it seems, lizards are remarkably talented at staying put when necessary, even during high force wind events, such as a hurricane. Scientists had an incredibly hard time knocking the lizards off (and if they did fall off, there was padding in place to keep them safe).
Biologist Colin Donihue, after recently visiting small islands in the Caribbean and studying the anole lizard, was given a remarkable opportunity.
Not long after his team’s departure, two hurricanes hit the islands, both with wind speeds clocked above 200 kilometers per hour.
The team returned as soon as the coast was clear, and examined the lizards present immediately after the devastating storms.
What they found was interesting. After a quick examination, it was noted that the lizards most present after the storm had larger toepads, longer forelimbs, and shorter hind limbs than what was measured before the storm.
This gave the team from Harvard an idea. Could they replicate a hurricane like experience under a controlled setting and actually show if these traits are favorable? Since I have already shown you the video…. the answer is yes, they could.
It is thought that these traits allow lizards who live in such a climate to latch onto branches in small bushes and hold on for dear life until the storm has passed.
What makes this particular study so unique, is the chance to study a population before a large event, and immediately after. The scientists were able to directly measure the difference between the species and discover what sort of traits enhanced survival. This allows a direct measurement of natural selection, the idea of how evolution works.
While there many other possibilities besides a hurricane that could drive a lizard to have larger toepads or shorter hind limbs, the natural selection process is still present.
More importantly, this small study could provide a glance into how climate change affects species. With the heating of the oceans due to astronomically high temperatures, weather patterns change dramatically. This includes the frequency of large scale storms such as hurricanes.
With hurricanes becoming more common in the tropical areas, such as the Caribbean, this forces animals such as the anol lizard to either adapt or suffer. While it seems this remarkable lizard has developed a method to out ride the storms, and probably give them a severe advantage at rodeos if given the chance, much yet is to be discovered as to how well species adapt with the increasing temperatures, ocean acidification, and frequency of severe weather patterns.

For centuries, one of the biggest mysteries of the human race as been aging. Through science and medicine, we have been able to increase the quality and longevity of life, but at some point we all reach an age where our body stops working and we die.
A few decades ago, scientists came across a structure within cells that appears to contribute to aging, called telomeres. Today, I want to spend time discussing what they are and the pseudo-scientific claims associated with them.
The Discovery of Telomeres:
I find the discovery of telomeres a remarkable achievement of women in science, and I want to spend a few moments discussing the brilliant scientists responsible.
In 1933, Barbara McClintock, and American biologist focusing on chromosomes and their role in the life of the cell, discovered that when the very tips of chromosomes were missing, they became “sticky” and formed with other parts of the chromosome. This phenomenon is called ring chromosomes From this work she hypothesized that there must be a structure responsible for protecting the ends of chromosomes and named them telomeres. These telomere structures would be non-coding regions of DNA that if lost, would not directly harm the cell.
Barbara McClintock later became a well renowned biologist, contributing to the understand of meiosis (division of cells producing the two sex cells, sperm and eggs), mitosis (normal cellular division) and other cellular processes. She eventually went on to earn the Nobel Prize in Physiology or Medicine in 1983 for discovering transposable elements, segments of DNA that jump from one chromosome to another. She remains to this day the only woman to receive this award unshared.
Fast forwarding to the 1970’s a man named Alexey Olovnikov learned through experimentation that DNA replication, a process necessary before a cell splits into two, occurs with an error. After each division, the telomeres cannot be fully replicated, and a small segment of telomere DNA is lost. Dr. Olovnikov further suggested that after a certain amount of cell divisions, the telomeres are lost and the cell dies.
After discovering this phenomenon, Olovnikov predicted that there should exist an enzyme responsible for correcting this mistake and re-lengthening the telomeres. He dubbed it telomerase.
Sure enough, a few years later, Elizabeth Blackburn discovered telomerase and showed it did indeed restore the length of telomeres. From this work, Blackburn received her Nobel Prize in 2009, along with Carol W. Greider and Jack W. Szostak.
With all of this research compiled together, it shows that shortening of telomeres is at least in part contributing to the aging process
How Telomeres and Telomerase Work:
The structure of telomeres is relatively unique, but simplistic in its own way. Telomeric DNA, at the very ends of chromosomes, consist of long sections of repeating nucleotide sequences. Remember, the four “letters” of DNA are A,T,C,G. In species, telomeric DNA all have repetitive sequences, but they differ slightly depending on the organism.
Most vertebrates (including humans) for example have the sequence TTAGGG. Some plants have TTTTTTAGGG.And yeast have TCTGGGTG.But all are relatively similar to each other and are repetitive.
In addition to DNA, there are also proteins involved in creating the structure of the telomere. Certain proteins bind to the telomere section of the chromosome, and provide structural support, and even wrap the DNA like a knot on the end of the rope. This complex structure thus prevents any damage that could occur from the cell (think of the aglets on the end of your shoelaces).
However, as previously mentioned, during DNA replication a small portion of telomeric DNA is lost. Once the telomeres are gone, important genomic DNA is damaged and the cell recognizes it’s time to die.
But that is not always the truth. In certain cells, telomerase is expressed to re-lengthen telomeric DNA.
Telomerase is a special type of enzyme that is made up of protein and RNA. The RNA included into the protein section will recognize the repetitive sequence, and the enzyme can then replace the missing sequences left during DNA replication.
After the discovery of telomerase, many people were interested in discovering how to use telomerase as a molecular fountain of youth. However, it was quickly realized to be quite dangerous.
Normal adult cells have low expression of the telomerase enzyme, providing a natural end point when the cell must die. Cancer cells however, need to grow without being hindered by the natural fuse telomeres provide. Therefore, they express telomerase in abundance. It is reported that 85-90% of cancers have overexpression of telomerase. This suggests that having telomerase active and available for cells may give them a predisposition to cancer, which of course would not be favorable.
Much work has been done to develop a method of lengthening telomeres including drugs, and genetic modification, with little success. Therefore, scientists have been trying to understand how environment and other events can shorten telomeres, and thus shorten our lifespan.
The Not-So Scientific Claims of Lengthening Telomeres:
For the past few years, there has been much work done trying to understand if shortening of telomeres is caused not only by regular aging, but also by stress or other life events. And so far, the data has been inconclusive.
Part of the problem is finding trends involving telomeres. There is a wide diversity of telomere length among human individuals, which it makes it difficult to study.
In turn, modelling stress is challenging, and very little work has been done to suggest telomere length is actually affected by stress. The only meta-analysis provided on stress-induced telomere shortening showed a very small decrease in telomere length with higher stress. However, there are so few studies, there appears to be publication bias. Once the bias is corrected, the trend dissapears.
This however, has not stopped the pseudo-scientific community for jumping on the bandwagon.
Hundreds of articles and pseudo-scientific experts claim that decreasing stress, changing diet, meditation, exercising, vitamins and antioxidants, herbal supplements, essential oils, and many other things can lengthen your telomeres and give you longer life.
Even Elizabeth Blackburn, the woman who discovered the enzyme telomerase, claims in her book The Telomere Effect: A Revolutionary Approach to Living Younger, Healthier, Longer that changing your lifestyle has a profound effect on lengthening telomeres and promoting longer life.
“One study has found that people who tend to focus their minds more on what they are currently doing have longer telomeres than people whose minds tend to wander more. Other studies find that taking a class that offers training in mindfulness or meditation is linked to improved telomere maintenance.”
–Elizabeth Blackburn, The Telomere Effect: A Revolutionary Approach to Living Younger, Healthier, Longer
Unfortunately, there is no evidence to support these claims.
In fact, while it seems that telomeres do in fact play a role in the aging process, we have no idea how large of a role it plays. Even if we can lengthen our telomeres back to normal levels, would it make a huge difference? Probably not as big as we think. Would there be another factor that contributes to aging once we solve the telomere problem? I/ guessing yes.
The truth is, aging is a complicated process and likely is a result of multiple factors. Telomeres do seem to be one of those factors, but only lengthening telomeres may not be enough to significantly lengthen your lifespan.
The science of telomeres is a beautifully example of science and pseudo-science. Hard work and many years have discovered a novel section of chromosomes, and has given us a deeper understanding of how cellular death occurs. Pseudo-science has then taken up the information, and twisted it to sell snake oil. So the next time someone tries to tell you about this magical product that lengthens telomeres and prevents aging, be sure to set them straight.
With that said however, I look forward to the discovering more about telomeres and their contribution to aging. It’s always nice to discover one piece of the puzzle, no matter how big or small it is. I suspect in the next few years, an update will be added to this post, it just won’t be on how to lengthen telomeres with yoga or diet.

While browsing through my science news items this morning, I came across an article discussing the effects probiotics have on heart health. Seeing as I haven’t yet discussed probiotics on this blog, I thought this would make a good opportunity.
The article was published in Authority Nutrition. Within there are many citations, and appears to be evidence based, but does the evidence actually support the claim? Turns out not really.
Probiotics: A review
Before I get into the article, I want to make sure everyone is on the same page when it comes to probiotics.
The definition of probiotic is officially described as: denoting a substance that stimulates the growth of microorganisms, especially those with beneficial properties (such as those of the intestinal flora)
Before researching for this post, I was under the impression probiotics were a recent invention (within the last few decades) and was surprised to find that the idea is much older.
The hypothesis that your gut microbiome (the good bacteria living within your gut) could be altered was first coined by Russian scientist and Nobel laureate Élie Metchnikoff, who in 1907 believed that aging was caused by bad bacteria that excreted harmful substances into the gut. These toxic molecules then act on the body and cause characteristics of old age.
After witnessing that certain European countries who drank milk fermented by lactic-acid bacteria had relatively long healthy lives, Metchnikoff decided to incorporate the sour milk into his diet. Soon afterwards he had convinced many of his colleagues, and doctors were prescribing sour milk to treat various ailments.
After the initial sour milk product, many foods have been developed and labelled through the decades as a probiotic; including yogurt, buttermilk, kombucha fermented tea, and sauerkraut.
Recently, probiotics have gained momentum with the release of probiotic pill captures, or fermented drinks (such as kombucha) containing what is believed to be good bacteria meant to alter your gut flora and cure a plethora of diseases.
And the data suggests that the usage of probiotics has increased with the release of these new products. Data from the 2012 National Health Interview Survey show about 4 million U.S. adults use or have used a probiotic.
Nowadays, you can’t enter a grocery store without seeing 10 different brands of probiotics, all promising to cure disease or maintain gut microbiome diversity.
The Science Behind Probiotics:
When you type in the keyword probiotic into PubMed, 18,605 results are returned, with an exponential growth starting in the early 2000’s. However, much of the data coming out suggests probiotics are not as beneficial as companies would have you believe (as always).
Much research has been preformed discussing what scientists call the microbiome (the variety of bacteria that exist within us or on us , primarily referring to the intestine and skin.
Evidence suggests that an unhealthy microbiome with the wrong type of bacteria, or too little of good bacteria can contribute to many health defects. Those with disrupted microbiota can experience digestive tract issues, and possibly have an increased risk of developing heart disease, diabetes, weight gain, and many other medical issues. While the evidence is young, there does appear to be a link with the gut microbiome and many diseases we fight today.
Recent mice studies further confirm this hypothesis. Unhealthy mice who receive a microbiome replacement with the microbiome of another healthy mouse, under go a great change. One example shows that mice who are typically more afraid (hide, don’t jump from ledges, etc..) and get their microbiome replaced with mice who are more courageous, appear to become more brave. Other studies have shown that normal mice who get a microbiome replacement with obese mice end up actually gaining weight to similar levels as the original obese mouse.
This preliminary data needs to be further evaluated, but it does bring forward an interesting discussion of how microbiomes make up our human personality.
And so, probiotics on the surface have the potential to modify our microbiome and increase the health of those who take them by replacing them with beneficial bacteria. It seems that probiotics have in general two types of bacteria; Lactobacillus and Bifidobacterium.
However, these probiotics have mixed effects when it comes to the claims companies promote. In short, they are not the miracle cure.
Probiotics have been shown to relieve symptoms of certain medical ailments, such as inflammatory bowel disease, irritable bowel syndrome, or diarrhea caused by antibiotics. These however have not been conclusively tested, and much more work needs to be completed before we can actually consider probiotics a valid treatment.
What does seem to be clear though, is that if you are not suffering from a true, diagnosed medical disease, there is little or no benefit of taking probiotics. So don’t think of probiotics as something everyone should be taking. And if you have a compromised immune system for whatever reason, there is a risk of developing infections. Therefore, it is best to avoid probiotics.
Probiotics Contributing to Healthy Hearts:
Getting back to the article I initially found today, what I found was even more suspicious evidence suggesting probiotics are able to prevent heart disease and lower cholesterol.
The article is titled “Do Probiotics Benefit Heart Health?”and is on the surface a well cited article with what appears to be good information. The news item covers several review meta-articles that suggest probiotics decrease your cholesterol, your blood pressure, inflammation, and triglycerides.
However, after checking the sources my suspicions were confirmed.
Several review articles were cited, each being a meta-analysis of multiple studies involving human subjects. Almost all of which seemed to be double blind, placebo control studies. And there does appear to be at least some interesting data. However, these articles to the best of my knowledge are not using commercially available probiotics. In fact, I had a difficult time trying to find out exactly how much bacteria was added, and how it compares to those on the market.
In addition, I also found articles published in journals such as BMC Complimentary and Alternative Medicine that publish articles supporting traditional Chinese medicine (in children I might add), acupuncture, and other pseudo-scientific methods. This suggests to me the “peer review” of these journals may not stand up to the standards of evidenced based articles.
Being as probiotics are a drug, you would expect to find any evaluation of the proper dosage and potential toxicity (in this case probably likelihood of infection), but I found none.
All in all, the evidence provided by this news item does not impress me. It is impossible to prove anything in science, but these articles to me fall extremely short of suggesting probiotics contribute to lowering cholesterol or cure heart disease. The news items does not explicitly say that probiotics are the miracle cure, but I don’t believe it leaves the viewer with an accurate statement of the current research, and is not as evidence based as it suggests. There was however one true statement in the news item. Every article mentioned used patients either with high cholesterol, high BP, or high triglycerides. Therefore we cannot make the claim probiotics prevent high cholesterol or high BP
So far, I cannot conclusively say probiotics are completely useless. There does seem to be preliminary evidence suggesting benefits to those with medically diagnosed diseases, and the evidence of reducing cholesterol levels and preventing heart disease is shaky at best.
There seems to be no evidence suggesting it should be taken for normal healthy individuals, and there is too much discrepancies between the companies to suggest all of them work the same. If indeed there is a benefit towards ingesting one type of bacteria, the probiotic industry needs to police themselves and use the proper amount and type of bacteria shown to be clinically effective. There is very little evidence on safety of probiotics, and little evidence on efficacy over long periods of time.
To wrap up, until more evidence is released showing probiotics are more effective, and the probiotics are controlled by an agency responsible for developing them safely, stay clear of probiotics.

As someone who actively researches cancer, and constantly works with cancer survivors, I hear a remarkable amount of crap dealing with “miracle cures” and the always comical “Big Pharma is hiding the cure for cancer”.
But one of my biggest pet peeves is the conversation revolving around marijuana and cancer.
But before I get into this specific article, I want to rant quickly of the various and completely fake miracle cures that exist supposedly to cure cancer.
Black Salve– There has been quite a bit of news recently revolving around black salve or Cansema® in the news. This product is a topical paste meant to be administered on skin, covering cancerous lesions, and claims to destroy cancer cells specifically while leaving normal tissue alone.
“Cansema® is very selective in its action, it is escharotic to cancerous tissue and only mildly irritating (i.e. “rubefacient,” causing redness) to healthy skin.”
“Thousands of individuals and physicians from around the world have used the product, with no results only in cases where the cancer was misdiagnosed (i.e. there was really no cancer to begin with). Empirical case studies to date show that it has successfully removed (cured) every malignant carcinoma, adenocarcinoma (i.e. breast cancer), and even melanoma, to which it has been applied.”
The ingredients of black salve notoriously vary, but usually include bloodroot, ginger-root, ganglia, red pepper, and zinc chloride.
Black Salve at face value may seem as a wonderful cure, but in reality has no scientific evidence supporting it works, and in fact shows to be devastating to normal tissue.
Dr. Steven Novella, a medical doctor and prominent science communicator, describes black salve as “an acid” burning away healthy and cancerous tissue alike, completely destroying tissue of all kinds. If you don’t believe me, spend about 5 minutes searching images of black salve treatments and see for yourself.
As a testimonial, a recent nurse diagnosed with ovarian cancer was convinced this pseudo-medicine would cure her late stage cancer. So instead of getting potentially life-saving surgery and chemotherapy, she believed a medical quack, and ended up severely burning her skin ultimately passing away from her advanced disease. The fact that she was a nurse proves even educated individuals who should know better can be conned when facing death.
Diet– I’m sure many of you have heard about one diet or another that has reportedly cured cancer in individuals, and to the disappointment of some, I’m here to say that they all are lies.
Here are some common examples
Alkaline diet- a diet involving adjusting your pH of your blood with food/beverages. The “hypothesis” is that cancer cells live in a normally acidic environment ( usually true) and by adjusting your diet to avoid acidic food, you can destroy the cancer (garbage). The reason this does not work is largely due to our bodies amazing ability to regulate our pH, and believe me this is important. If our blood pH goes below or above the normal range, we will experience severe medical issues. That’s why your kidneys, lungs, and other buffer systems keep the pH tightly in check. So that alkaline water that seems so hip to drink…… is just an expensive con. And so is everything else with the alkaline diet.
Superfood diet- Ah yes. Kale, everyone’s favorite cure for cancer. Don’t get me wrong, Kale and other leafy greens are wonderful to eat (spinach is my favorite), but we shouldn’t let our love of good food get confused with curing diseases. Eating these foods is definitely more healthy than a burger from McDonald’s everyday, but there doesn’t seem to be any evidence that super foods specifically cure/prevent diseases, including cancer.
Alternative Medicine– I don’t want to get into alternative medicine as a whole with this blog post, but suffice to say the crap people sell under the umbrella term alternative medicine (Aromatherapy, Homeopathy, Hollistic medicine, Herbalism, Nautropathy, Acupuncture, etc…) is not beneficial to anything, and should not be used as a replacement for standard care.
Going back to the article that prompted me to write this blog.
The news item is from USA Health Times, which seems to be a site fully designed for the sole purpose of making marijuana sound like a cure for EVERYTHING. But once you open the many articles pushing pot, the evidence is lacking.
In case you don’t know, marijuana or cannabis, is a plant originally from Central America known around the world for its psychoactive capabilities. These psychoactive traits come from cannabinoids, molecules that act on the central nervous system and immune system. The two most commonly discussed cannabinoids are delta-9 THC and cannabidiol (CBD). THC is responsible for the “high” associated with marijuana.
For many year now, it has been a common theme among marijuana enthusiasts that pot should be used to treat cancer, and “Big Pharma” doesn’t want you to know about it.
The real truth is that science has yet to explicitly prove THC or CBD as a cure for cancer.
There does seem to be some interesting results suggesting TCH, CBD, or a combination of the two as a potential cancer treatment, but none of them are close to conclusive.
After doing a quick pubmed.com search, I found several of articles testing purified TCH or CBD and testing effects in vitro (on cells directly) or in vivo (in animals, typically mice in this case). So far the experiments seem interesting, but not especially promising.
Going back to the USA Health Times article, they specifically describe a “Men’s Health Study” that showed cannabis users have a significant decrease risk of developing bladder cancer than those that don’t.
But, I have not been able to find the study on any site. And from the description, it looks like the data was manipulated to be significant.
“Over 16 years, they found 89 Cannabis users developed bladder cancer compared with 190 of the men who did not report cannabis use. After dividing the study up by age, race, ethnicity, and body mass index, cannabis use was associated with a 45% reduction in bladder cancer incidence.”
After separating the individuals into multiple groups, does it still make a significance? Who knows!
The long and short of my point is this: when someone tells you that Item X is a cure-all for everything, it’s probably not.
So far the evidence for marijuana, THC, or CBD oil is lacking. Perhaps someday there will be evidence that changes my mind, but I doubt it.
And part of the issue with the love for pot and all other miracle cures cancer is due to the massive amount of hate for Big Pharma. “It makes more money to treat a disease, than to cure it.” “Big Pharma has the cure for cancer, but they are hiding it to make money.” Bulls***!
Here’s the truth. Cancer is not one disease, but a collection. There are over 100 different types of cancers, each of them with their own complexities. Even more so, individuals who may even have the same cancer probably face different struggles. Genetic profiling of cancers between patients has shown vast differences even within the same cancer type. So finding just one cure for all cancers seems extremely difficult.
And even if someone found a cure for cancer, why in the world would they hide it? The immediate fame this person would achieve is likely invaluable, surely not even Big Pharma could afford that. Not to mention how difficult it would be to not tell the world? Let’s face it, humans have a tendency to keep secrets about as long as it takes to turn on the phone and tweet. So for those who believe it’s locked away somewhere, it’s unlikely.
As I come to the end of my rant, I would like to mention just one thing. I have nothing against marijuana. If the evidence turns around, I will change the title of this post to Marijuana Is The Cure For Cancer, Hallelujah!
But something tells me that won’t happen. So please, if you know someone or if you yourself have cancer, do not fall victim to the con artists telling you pot or any other miracle cure is better than scientifically based treatments. Listen to your doctors. Find credible sources not trying to sell you snake oil.

Note: This post is not meant to give medical advice. As I have already mentioned, if you are struggling with a medical disease, please see a physician for proper medical advice.

Recently, I found an article published on Medium describing how the 1990’s sitcom Friends is responsible for the “downfall of western civilization.”
The whole article seemed to be just a little over the top, so I decided to give a thorough reply on this blog page.
In case you have not seen the article I am referring too, follow this link to give it the quick once over.
And if you are like me, you were alive in the 1990’s and early 2000’s and you probably owned a TV set. While many other shows were popular during the 1990’s, it’s really hard to ignore the show Friends, a comedy sitcom focused around six quirky friends struggling to establish their lives in New York City.
One of the main characters, Ross Geller, is a scientist. More specifically, he is a paleontologist who begins the show working at a museum, and later ends up as a professor at a prestigious university.
Throughout the whole series, a whopping 10 seasons, Ross is constantly picked on for his profession and is largely ignored by his friends when discussing his work. These exchanges constantly get a laughter from the studio audience.
David Hopkins, the man behind the original article, claims that this visualization of “picking on the smart people” is what caused the downfall of our civilization and likely contributed to the scientific illiteracy we see in today’s society.
“Yes, my theory is that Friends may have triggered the downfall of western civilization. You might think I’m crazy. But to quote Ross: ‘Oh, am I? Am I? Am I out of my mind? Am I losing my senses?” ”
-David Hopkins, “How a TV Sitcom Triggered the Downfall of Western Civilization.”
I think that is a gross exaggeration. And let me describe to you why.
Friends is not the first and not even the worst:
Maybe intellectuals have always been persecuted and shoved in lockers, but something in my gut tells me we’re at a low point — where social media interaction has replaced genuine debate and political discourse, where politicians are judged by whether we’d want to have a beer with them, where scientific consensus is rejected, where scientific research is underfunded, where journalism is drowning in celebrity gossip.”
-David Hopkins, “How a TV Sitcom Triggered the Downfall of Western Civilization.”
The largest issue I see with Mr. Hopkins complaint, is that Friends is not the first show to have a scientific/nerdy guy who was picked on during the show. Do we all remember the show Cheers? I admit, it’s a little old for my generation, but I have seen the show in it’s entirety and this show has two main characters similar to Ross that are ostracized for their intelligence. Anybody remember Diane Chambers, who was constantly picked on the gang at Cheers for her fascination with classical books, plays, and overall interest in learning? Or perhaps Fraiser Crane, the psychologist who was a bore for basically the first two seasons of the show until he became a regular who drank more than he treated patients (and let’s not forget his wife Lillith).
Now sure, Fraiser ended up receiving his own show, but even on his own show him and his brother Niles are picked on constantly for their intelligence and love of the finer things. And let’s not forget the dozens of other shows that constantly bully geeks, nerds, and dorks on mainstream television. Steve Urkel on Family Matters? Lisa Simpson or Milhouse Van Houten on The Simpsons? Carlton on The Fresh Prince of Bel-Air? All of these characters came before Ross was a twinkle in the producer’s eye that invented the character. If anything, the character Ross added to the description of nerds in mainstream media, and was likely developed to be similar to other nerds on other TV shows.
Ross was not alone in his suffering:
Sure Ross was picked on. Quite a bit actually. But he was not the only main character in the hot seat. Basically every single character was picked on religiously throughout the show. Joey Tribbiani, the lovable aspiring actor, was constantly bullied for his stupidity and by the end of the series was even written to be almost to stupid to be real. Monica was continuously made fun of her obsessive cleaning and organized personality. Chandler, the sarcastic one, was picked on not only for having a job no one could remember, and everyone thought he was secretly gay. The fact of the matter is, at the end of the day every character, even the small characters like Gunther, were picked on for their personality an equal amount. And at the end of the day, it was the diversity of the group that made the group fit so well together. If we want to specifically say Ross’s character contributed to scientific illiteracy or high point in bullying nerds, I think we would learn more evaluating the community as a whole.
2004, a year with coincidences:
Sure it does seem like the end of Friend’s marked the beginning of scientific devastation in our civilization, but it’s really all a coincidence. It’s not good science to automatically correlate events happening within a year together. In 2004, Mr. Hopkins was a teacher who constantly saw bullying of nerds, President Bush was elected for a second term, Paris Hilton was a big deal, etc…..
But what does this really show us? It’s easy to look at any information from one year and make some random conclusion.
For example: I randomly choose the year 1998.
Google was born. Bill Clinton denies he had sexual relations with that woman, and a huge financial crisis hits a large portion of Asia.
Conclusions? Bill Clinton’s lies caused Google to form to prove him wrong, and this causes a financial crisis in Asia.
Now I know this is ridiculous, And I spent about 30 seconds writing that to be as ridiculous as possible, because there is no good reason to look at any year and try to piece information together.Correlation does not always correspond to causation.
If you look at any year in particular, you can probably fit any narrative you wish to defend your claim, and that is not the purpose of good science. Scientists spend time objectively spending time looking for trends, and then try to find an explanation for them. More importantly they look for other explanations to explain the phenomenon besides their own theories.
And finally to sum up my main issue with this whole idea, why should we put all the blame on TV shows? Sure we all watch TV and that has an impact on our lives, but WE are the ones choosing what to watch. If there is anyone to blame, it is ourselves for watching American Idol or The Bachelor over The Discovery Channel and National Geographic. Rather than putting actors and musicians on the pedestal, we should put scientists and inventors in the public eye. We should inherently be more interested in news items that expand our knowledge rather than the celebrity gossip. And this has been a problem looooong before 2004. Just as we shouldn’t blame video games on increasing school shootings, we shouldn’t blame TV for stupefying civilization, we should blame ourselves.
So Mr. Hopkins, I think we are trying to say the same thing. But this issue is much larger than one sitcom. It’s the society in general.
And here are the suggestions I have to improve our society.
Stop believing everything people tell you. Question as much as you possibly can. Even your professors or teachers, because more than likely they are wrong about something (not always on purpose).
Don’t Enter an Echo Chamber:
It is extremely easy on the internet to find sources that on the surface appear legit, but below end up being complete garbage. If you are looking to prove something you believe in, don’t just look for sites that confirm your suspicion. Spend just as much time looking at the other side of the argument and hear what they have to say. If you spend your whole life only reading articles that support your belief system, you are entering into an echo chamber that can in the long run harm the knowledge you have developed.
Be Willing to Change your Opinion:
People are wrong all the time, myself especially. And this is extremely hard to get used to, but stop being bothered by being wrong. It happens. Rather than digging yourself into a faulty belief, say “Oh yeah, I am wrong, I need to change my opinion.” There is absolutely nothing wrong with that.
Dear God Yes Read a Book:
Mr. Hopkins said it well. Reading a book rather than watching TV is a great way to expand your knowledge, whether it’s fiction or non-fiction. Read books that question your deepest belief system. You cannot limit your books to your safety zone, it is much more harmful than it is helpful.
Have a Scout Mindset:
I think it’s safe to say that all of us are curious. But some of us inherently are more curious or more interested in feeding our curiosity than others. So the next time you wonder why the sky is blue, don’t just think about it for 30 seconds, look it up. If you can’t find an answer that makes sense, keep digging until it does make sense. You will learn so much. Basically look for THE answer, not YOUR answer.
For generations, people have always wondered what life might exist in the universe besides ours. It has become a hot topic in movies, books, and of course, science.
Before even reaching space, humans have always hypothesized about “The Great Beyond” So far we have not found alternative life, but we have made significant progress.
On major discovery is exoplanets. It seems pretty obvious that extraterrestrial life must exist on another planet, however before we can find life, we must find planets that can support it.
An exoplanet by definition is a planet outside our solar system that orbits a star(1). The first scientific detection of an exoplanet was in 1988, although we have hypothesized the existence of exoplanets for over 100 years.
Although we know have the technology to find exoplanets semi-regularly (the current number of known planets is almost 4,000), scientists are looking for planets in what is called the habitable zone (also called the Goldilocks zone). This arbitrary zone describes planets that are just far enough from their sun to support liquid water, but not too far to cause it to freeze.
Of course, it takes more than possessing water to host life on a planet. Since, we only have one example to go off of, scientists are looking for planets most similar to our own. As of now there is an estimated 40 billion planets Earth-sized and orbiting the habitable zone of stars we have yet to discover(2). It’s these planets that we are most interested in.
In fact, recently a group of scientists met and explained how water should not be the only candidate for a planet within the habitable zone able to host liquid water. Certain geological structures are necessary to allow growth of organisms and proper collection of minerals that can give life a better chance (4).
With new discoveries and scientific advancements, researchers are also trying to unravel the mysteries of exoplanet geology.
The research even has a name. Exogeology. This area brings together scientists from the field of astronomy, planetary scientists, and geologists together with the task to reveal what exoplanets look like from a geological perspective(3).
One of the best tools we have to decipher exoplanet surfaces, called the Z machine, has just begun scratching the surface in exploring exoplanet material.
This machine is currently the largest high frequency electromagnetic wave generator, and its purpose within this context is to test various materials under extreme temperature and pressure (5).
While we are not able to travel to exoplanets yet, we are now working to understand them as best as possible by working to create artificial environments we would normally see to try and discern how exoplanets behave.
With more information, we can better understand exoplanets, and focus our attentions on those with the best chances of other beings. Perhaps one of them may write a blog with us someday.

Since the 1980’s, scientists have been making shapes out of DNA. In recent years, technological advances have increased to the point where we can now make beautiful designs from the molecule that encodes our existence. It’s called DNA Origami.
The idea is relatively simple. A single strand of a DNA molecule is used as a scaffold. The scaffold is then molded to design the shape desired with “staple molecules” or short complementary sequences of DNA that will fold the scaffold strand.
With the right computer programs, you can make a wide variety of shapes, including smiley faces, teddy bears, or even a box equipped with a lid and a lock.
Of course, it’s always fun when scientists get to play around, but there are some pretty impressive applications to this technique as well.
Scientists have been adapting DNA origami to form various objects (a sphere, or a box) able to carry drugs to a target site within the body. For example, chemotherapy and immunotherapy drugs for cancer patients wreak havoc on the body. However, if they are able to be transferred to the tumor itself, not only would you have reduced toxicity, you would also potentially increase your chance of destroying the tumor.
Others have also worked to create “nanobots” (extremely small functional robots) from DNA. These nanobots reportedly have the capability of being pre-programmed to travel to certain areas and perform basic functions. While the technology is very new and has not been tested in humans yet, it appears to be a promising avenue of research.
While DNA origami technology has come a long way, scientists have been limited on one aspect; size.
Currently, the largest a DNA origami shape could be is about 100 nanometers. If larger than that, the shapes loose their stability.
Yesterday however, four papers published in Nature describes methods of evading this problem.
By creating small DNA origami V-shaped structures and allowing them to link together, scientists have overcome the size restrains. These structures can then be used to make large, stable structures like the sphere below.
These larger spheres then possess the capability of carrying a wide variety of items, including drugs for various diseases.
Researchers also developed a new design software that can generate pictures and make DNA origami representations of pictures, like the Mona Lisa for example.
Another complicating aspect to DNA origami is price. Creating the proper strands to make these complex structures takes a lot of time, and a lot of resources. One way to overcome the price is to develop a long single stranded DNA molecule that possess not only the staple and scaffold strands, but also section able to break apart the other sections of the same molecule (called a DNAzyme). This one strand will therefore be able to cleave the scaffold and staple strands from itself and be able to make the structure, thus decreasing the cost.
The advancement of creating DNA structures has been fascinating to watch the last decade, and with these new advancements, DNA origami technology will quickly become a pioneer technique in a variety of scientific fields.
