While efforts to keep the house warm are noble, the advice is not supported by science. Cold cannot be let in because it doesn’t exist! Well, sort of.</p> Fri, 29 Nov 2024 15:20:43 +0000 Angelina Lapalme 10182 at /oss /oss/article/medical-student-contributors-health-and-nutrition/nutrafol-holy-grail-hair-loss-or-overpriced-supplement <p>Hair loss is a normal component of the natural hair growth cycle. Hair growth occurs in three stages: the growth phase where the hair grows for around 2-7 years, the transition phase where the follicle starts to shrink and hair growth slows for around 2-3 weeks, and the resting phase where the hair falls out at the end of this phase at around 3- 4 months. The falling out of the hair strand is necessary so that a new strand can take its place, and the cycle can begin again.</p> Fri, 08 Nov 2024 15:56:16 +0000 Daniela Padres 10152 at /oss /oss/article/student-contributors-did-you-know-general-science/chemistry-spider-webs <p>“The itsy-bitsy spider climbed up the waterspout. Down came the rain and washed the spider out…”. But funnily her web remained unscathed. How?!</p> <p>With Halloween having just passed, we saw spider web decorations completely overtake houses, adorn witch hats and even candy wrappers. Despite my fear of spiders, I have an immense amount of respect for them and not for their contributions to our environment. I admire them because spiders are quite the biochemists, and their webs are a product of a biochemical reaction that we can only attempt to reproduce in the lab.</p> Wed, 30 Oct 2024 15:22:54 +0000 Angelina Lapalme 10130 at /oss /oss/article/critical-thinking-student-contributors-health-and-nutrition/instant-coffee-and-acrylamide-should-you-be-worried <p>Coffee is a staple beverage for millions of people worldwide, consumed in endless scenarios: catching up with a friend, powering through an intense study session, or simply kickstarting the day.</p> <p>From the classic drip coffee and trendy cold brew to the precision of the French press and the intensity of espresso, there are countless ways to make the perfect cup of joe.

Acidity is often measured on a pH scale. This is because Danish chemist <a href="https://www.sciencehistory.org/education/scientific-biographies/soren-sorensen/">Søren Peter Lauritz Sørensen</a> invented the concept of pH as a convenient method for expressing acidity. Acidic things have a low pH whereas alkaline things have a high pH.</p> Thu, 17 Oct 2024 22:09:08 +0000 Daniela Padres 10119 at /oss /oss/article/student-contributors-did-you-know/hardest-working-caffeine-addicts-bees <p>Wake up, go to work, seek out caffeinated beverages, get food, share food with others, store leftovers for later, and repeat. This routine sure does sound familiar, doesn’t it? With over 3.5 billion employed people worldwide following a variation of that basic routine, I wouldn’t blame you if you thought I was talking about humans. But what if I told you I was actually illustrating the day in the life of a bee? As it turns out, humans and bees have very similar lifestyles. They protect their own, work together during the day and seek the refuge of their hive at night.</p> Fri, 11 Oct 2024 14:30:52 +0000 Angelina Lapalme 10110 at /oss /oss/article/medical-student-contributors/migraine-more-just-bad-headache <p>A migraine is often misunderstood as just “a bad headache,” but this assumption couldn't be further from the truth. Migraines are a complex neurological disorder, far more debilitating than a typical headache, with a significant impact on patients' quality of life. For some, the pain is relentless and pounding, and it comes with a slew of other symptoms that make day-to-day functioning a challenge. Moreover, the struggle of enduring migraines is often worsened by the feeling of having an invisible disorder and of being doubted.</p> Fri, 04 Oct 2024 16:18:09 +0000 Hosna Akhgary 10101 at /oss /oss/article/medical-student-contributors-general-science/why-do-some-people-breathe-bag-when-hyperventilating <p>“Just breathe!” is probably the worst thing that you can tell someone who is hyperventilating. The fact is, they can’t! Whatever the cause of the hyperventilation, screaming and telling someone to just “calm down” may actually worsen the situation. Don’t fret, there is still a way you can help, and it is actually quite simple. Offer them a paper bag to breathe into.

The Greeks considered pollen to be the food of kings. There is a reference to bee pollen in the Bible. Ancient philosophers such as Hippocrates, Pliny the Elder, and Pythagoras believed in the therapeutic potential of bee pollen. So, it seems only natural that we, in the present day, would take a fascination with bee pollen.</p> Thu, 19 Sep 2024 15:03:05 +0000 Daniela Padres 10083 at /oss /oss/article/student-contributors-environment/botanical-sexism-really-blame-increased-pollen-allergies-urban-cities <p>The story starts with horticultural epidemiologist Thomas Ogren. His <a href="https://www.scientificamerican.com/blog/guest-blog/botanical-sexism-cultivates-home-grown-allergies/">major citation is that of the 1949</a> USDA Yearbook of Agriculture where it was recommended that “when used for street plantings, only male trees should be selected, to avoid the nuisance from the seed”. He claims this led to a major skew toward planting male trees in urban cities in the following years in attempts to reduce the work needed to pick up the petals, berries, and fruits produced by female trees.</p> Thu, 12 Sep 2024 18:25:36 +0000 Daniela Padres 10077 at /oss /oss/article/medical-student-contributors/serotonin-syndrome-too-much-good-thing <p>Serotonin, or 5-hydroxytryptamine (5-HT), is a neurotransmitter that plays a crucial role in various bodily functions, including mood regulation, behavior, memory, and gastrointestinal balance.
