The 5 Second Rule – A Scientific Examination

It’s a lazy Saturday and you’re at home having a leisurely lunch, watching YouTube on your phone while you eat a delicious bologna sandwich. The next thing you know, those crazy YouTube cats have made you laugh so hard that you drop your sandwich – what do you do? Do you throw the contaminated sandwich away? Or do you think to yourself “five second rule,” pick it up and continue eating? Everyone knows the 5 Second Rule: if you drop food on the floor, it’s okay to eat, as long as you pick it up within five seconds. A researcher at the University of Illinois found that 56% of men and 70% of women surveyed had heard of this rule (or its alternative version, the 3 Second Rule), qualifying it as a legit Western Cultural Phenomenon. So, is this real or what? Surprisingly, studies have given conflicting views as to what exactly the 5 Second Rule means for our health and welfare. Jillian Clarke, the researcher from U of Illinois found that food was contaminated within five seconds of being dropped onto ceramic tile inoculated with E. coli. She had some trials and tribulations in the course of her research – at first she was simply going to drop the food on the lab floor, but the lab floors turned out to be *too* clean. She also found that women tended...

What’s The Best Part About Being A Medical Student?

How would you define a “medical student”? In the simplest sense, a medical student is an individual (or creature, depending on which attending you’re talking to) who knows just enough to realize what’s going on yet not enough to be entrusted with any real responsibility. While this may seem demeaning to some, I myself find it to be absolutely fascinating. For instance, imagine being in the operating room as a medical student. You know what procedure is going on, why it’s being done, and maybe even what could go wrong (depending on whether you quickly googled the procedure during morning rounds). However, you are essentially free from concerns of making sure that the procedure goes exactly as planned and can instead appreciate the art of it all. You are there to learn and pretty much nothing else. What more could you want! The residents and attendings are there to make sure that the patient pulls through while you are there all scrubbed in to hold the retractor and watch the magic unfold. I recall being in a laparoscopic gastric bypass surgery where I was entrusted with the responsibility of holding the camera and following the surgeons as they did the resecting and suturing. It was at that moment I realized what a cool job this could be. The flexibility and opportunity to figure out what specialty you want to...

These Are The Weirdest Sleep Experiments Ever Conducted

The very nature of being human means that we strive to understand the world around us. Scientists have long considered experiments the best way to test a hypothesis and draw a conclusion. Over the last century, scientists have begun to study sleep more and more. We know it’s necessary yet we don’t fully understand it.  Such a vital function could contain so many important discoveries that we haven’t yet come across. In this infographic we look at some of the most bizarre sleep experiments. What were they, who ran them and why? Did we learn anything from them or did they go horribly wrong? Weird Sleep Experiments infographic by Mattress Online. On an article on Polyphasic Sleep, Yash Pandya also explores the benefits of this new research: As students, we all experience a lack of time at one point or another. There are just so many things on our plate that we must achieve in a short lifespan! Our decisions regarding priorities eventually boil down to a balancing act of the three-legged stool – education, social life, and sleep – with the last one ending up usually being cut. But what if I were to say that there is an alternative to the recommended 8 hours of sleep? Would you go for it? Looking around the world, people usually engage in monophasic sleep, which describes a pattern where one...

The Best Way To Write A Brilliant Medical Statement of Purpose

Writing a statement of purpose is a challenge for many students, but it should not be approached in a stressful manner. Once you have your structure down, you can start working. Achieving high scores is important for students, but the admissions committee also wants to know about why you decided to choose this career. There is more to a person than just test results.

Of course, you should be proud of all your achievements, but it is very important that you do it in a way that shows confidence,...

Your Next Box of Mac & Cheese Could Be Your Last

Most of us enjoyed mac and cheese from the box as children and we loved it! All the non-nutritious goodness that was filled inside that little box was what we wanted daily. Looking back on my mac and cheese filled childhood, I get a feeling of regret and that is because a new study has revealed that mac and cheese from the box has a toxic chemical called phthalate. Phthalates are chemicals of high concern. They are used in the plastics industry and are found in rubber coatings, adhesives, sealants, and printing ink, but they are not directly added into food. However, through the food packaging process, phthalates can find their way into food products indirectly when they leave from food contact materials. This is a serious problem. Phthalates are dangerous to pregnant women and children because many studies have linked prenatal exposure to phthalates with birth defects in children. They are hormone-disrupting chemicals that have been shown to threaten the health development of babies’ endocrine and reproductive systems. In order to protect people’s health, the EU has banned most phthalates for plastics in contact with fatty foods. However, the US has not taken this type of action yet. Per a new study by The Coalition for Safer Food Processing & Packaging, the average phthalate levels found in macaroni and cheese powder were more than four times higher than in...

How Much Your Health Affects Your Wallet

Smoking, fast food, and lack of exercise can both affect your wellness and your money. Learn how much bad health affects your wallet.  Creating positive health changes in patients can be a difficult task. Once habits are ingrained, they become harder to break. Exposing more pain points for these habits can change a person’s viewpoint and lead them to change. Physical inactivity and poor diet choices continue to surge, and a new motive is needed to help people improve their health. Smoking has been one of the biggest health concerns for decades now, but did you know smoking can cost a person between $6,500 and $13,500 a year? The average cost of a cigarette averages out to be around 31 cents, which comes out to $1,358 a year. The hidden costs come in the form of higher insurance premiums and loss of insurance credits. The total cost of smoking with these factors adds up to a much greater financial sacrifice. The increase in fast food consumption has also made for a costlier lifestyle. Consumers spend an average of $1,200 a year on fast food which can lead up to an additional $5,500 a year in healthcare costs. The caloric increase not only leads to weight gain, but is generally coupled with an inactive lifestyle as well. Physical inactivity, according to the World Health Organization, is the 4th leading risk factor...

How Exactly Does Gene Transfer via AAV Work?

Properly functioning genes within our DNA provide the blueprint for the production of proteins. Mutations affecting those genes can result in proteins with altered or zero function. Using gene transfer techniques might be an effective way to restore function of proteins within cells. Gene transfer can occur via adeno-associated virus (AAV) vectors because they can target both dividing and non-dividing cells to correct disease-causing improper protein function. Therapeutic genes loaded inside an AAV can correct defective or missing protein function by injecting the AAV’s therapeutic genetic material to restore function of the proteins. A capsid encases the genetic material of the vector and helps target delivery to specific cells. Once inside the targeted cells, an episome is formed from the vector genome which allows for long-term expression of the therapeutic molecule. AAVs are nonpathogenic and can be administered by intravenous drip or direct injection to target tissues. The unique life cycle of adeno-associated virus (AAV) and its ability to infect both nondividing and dividing cells with persistent expression have made it an attractive vector. An additional attractive feature of the wild-type virus is the lack of apparent pathogenicity. Gene transfer studies using AAV have shown significant progress at the level of animal models; clinical trials have been noteworthy with respect to the safety of AAV vectors. No proven efficacy has been observed, although in some instances, there have been promising observations. In this review, topics in AAV biology are supplemented with...
