How one perceives beauty is merely superficial
|
view preview
Beauty may be in the eye of the beholder, but what’s influencing our eye? Scientists reveal that it’s not genetics but life experiences that lead us to find one face more attractive than another. This finding furthers the on-going debate of nature versus nurture. Here's how the study went down: Researchers asked 547 pairs of identical twins and 214 pairs of same-gender fraternal twins to view 200 faces and rate them on a scale of one to seven, with one being the least attractive and seven the most attractive. A group of 660 non-twins then completed the same survey. If genes were more involved in facial preference, identical twins would have had similar ratings; if the influence of a familial environment carried more weight, fraternal twins w ...

Whether you're a chef, stay-at-home mom, or food euthanasiast, how food is handled and prepared is extremely important to preventing foodborne infections and food intoxications. As evident with how the coronavirus spread over to humans, millions of people suffer the symptoms of foodborne illnesses when an outbreak occurs. According to the CDC, millions of people are infected with foodborne illnesses every year. Most can be prevented by storing and cooking foods at their proper temperatures and preparing them under sanitary conditions. Here's a brief rundown on how to detect and avoid tainted food items.

Camel spiders!
|
view preview
Solifuges are a variety of arachnids found in deserts. While they are called Camel Spiders, they belong to a different order from true spiders. It may appear terrifying. However, it seems the internet blows its fear factor out of proportion. After a few photos circulated around the internet, outlandish claims about their astounding physical abilities and voracious appetite for human flesh arose. No. They cannot run at 30 mph. (They do run at 10 mph, which is still incredibly fast.) They cannot kill humans, although they have a painful, albeit non-venomous bite. They can only grow to about 6 inches. They do not subsist on a diet of camel stomachs. Solifuges are content with eating insects, small reptiles, birds and rodents. ...

True human tail (vestigial tail)

Only about 100 cases are documented around the world. The true human tail upon birth is caused by a lack of cell destruction of the distal end of the embryonic tail. According to some experts, the true human tail is not really a tail at all. It is thought to be linked to spina bifida or a hiccup in the natural human development process. While others thing that it is due to mutation of the genes that produce cellular destruction of the tail component As it is well known that it is derived from the most distal remnant of the embryonic tail. It contains adipose and connective tissue, central bundles of striated muscle, blood vessels, and nerves and is covered by skin while it lacks Bone, cartilage, notochord, and spinal cord.

A rolling stone gathers no moss
|
view preview
This guy brings new meaning to the phrase “A rolling stone gathers no moss.” The Venezuela Pebble Toad is a strange creature. It is typically found in mountainous regions, with many slopes and inclines. The toad is only about the size of a fingertip. As such, it is vulnerable to attacks from even a spider, like a tarantula. The Pebble Toad has an ingenious defence mechanism. When faced with a danger, it tucks its limbs and head under its body and tenses its muscles. Forming a ball shape, it begins to roll down whatever slope it happens to be on. This allows it to evade whatever predator may be pursuing it. Since they are so tiny and their muscles are so rigid, they take no damage from the bouncing and rolling. The Pebble Toad was featured in t ...

Bulletproof glass manufacturer 3M Security Glass placed this advertisement at a bus stop. There's apparently $3 million in cash inside there, behind their bulletproof glass. If you can break it, it's yours. Here's how bulletproof glass works...At first glance, bullet-resistant glass looks identical to an ordinary pane of glass, but that's where the similarities end. An ordinary piece of glass shatters when struck by a single bullet. Bullet resistant glass is designed to withstand one or several rounds of bullets depending on the thickness of the glass and the weapon being fired at it. So, what gives bullet-resistant glass the ability to stop bullets? Different manufacturers make different variations of bullet-resistant glass, but it is basic ...

Garden in a bottle
|
view preview
This miniature ecosystem has been thriving in an almost completely isolated state for more than forty years. It has been watered just once in that time. The original single spiderwort plant has grown and multiplied, putting out seedlings. As it has access to light, it continues to photosynthesize. The water builds up on the inside of the bottle and then rains back down on the plants in a miniature version of the water cycle. As leaves die, they fall off and rot at the bottom producing the carbon dioxide and nutrients required for more plants to grow. ...

Bonobos, Chimpanzees, and the 98% DNA Link

When it comes to the animal kingdom, we often find ourselves marveling at the diversity of species that inhabit our planet. Regardless of our differences, the more we delve into the intricacies of genetics and biology, the more we realize just how interconnected all life on Earth truly is. One remarkable example of this interconnectedness is the relationship between humans, bonobos, and chimpanzees. Despite the differences in their "personality" traits, our DNA tells a compelling story of our shared ancestry with these incredible primates. Bonobos and chimpanzees, our closest living relatives in the animal kingdom, are often viewed as two sides of the same evolutionary coin. While they share approximately 98 percent of their DNA with each ot ...

It's sore throat season, why does my mucus have red spots?
|
view preview
It's that time of year again when the weather starts to change, and we're more prone to getting sick. One such symptom that accompanies these seasonal illnesses is a sore throat. Sore throats not only feel like you've swallowed sandpaper, but they are also accompanied by coughing, congestion, and the production of mucus, sometimes with spots of blood. Firstly, mucus plays a crucial role in our respiratory system. It's a slippery, gel-like substance produced by the mucous membranes lining various parts of our body, including the respiratory tract. This viscous fluid serves as a protective barrier against invaders such as pathogens and irritants. It also helps keep these surfaces moist, allowing for proper functioning and efficient air exchang ...

Nipping Common Gardening Mistakes in the Bud

Following these simple guidelines can turn even the most fumbling gardener into a veritable Farmer John. Avoid over-wateringWatering is one of the most confusing and misunderstood gardening chores. Over-watering encourages shallow root systems, makes plants more susceptible to disease, and wastes water.

Anyone who used a PC in the 1990's most likely used one with the most popular operating system of its time, Windows 95. Although it reached EOL (end-of-life) status in 2003, Windows 95 doesn't appear to want to die. It has made appearances on smartphones, handheld devices, and tablets for quite some time now, and people don't seem to be getting enough of it. Thanks to a young programmer, we can now have Windows 95 running in almost any web browser using emscripten, an emulator that converts C++ code to JavaScript in real-time. It requires no downloads, plugins, or any special software. The emulator takes a minute to load up, but once you’re inside it, it’s surprisingly snappy.

Citric acid: a natural preservative?
|
view preview
If you are into purchasing organic foods, you are likely the type of person who reads the ingredients label of everything you buy. A common food ingredient found in organic foods is citric acid. The name of the chemical reminds us of citrusy fruits, but have you ever questioned why it is used, where it comes from, or how it is produced? Or do you simply trust the ingredients of products labelled 'organic'? Most consumers will assume that citric acid is naturally extracted from fruit sources, such as lemons and limes, and used as a "natural" alternative to chemical preservatives, but that's far from the truth. The citric acid found in jarred foods and beverages is typically manufactured in factories using a species of black mold called Asperg ...

Why is sand listed as an ingredient in my potato chips?

One advantage of being a science major is knowing fancy scientific words for everyday things. Since my teenage years, I developed the habit of reading the ingredients list before purchasing any packaged food item. Recently while searching for a snack at the store, I stumbled upon the potato chips aisle (admittedly, salty, crunchy snacks have always been a weakness of mine). Given how expensive everything has gotten lately, the more affordable budget brands peaked my interest. After quickly glancing over the ingredients of one bag, I noticed that "silicon dioxide" was listed at the end; in fact, it was a common ingredient in that particular brand's entire line of products! Knowing that silicon dioxide is the main component of beach sand, my ...

Growing Tomatoes and Peppers

Most vegetables do best in soil that is very high in organic matter. To increase the amount of organic matter in your soil, just add compost or manure. Before planting, apply well-decomposed compost at the rate of 40 to 60 pounds per 100 square feet of garden space. Don’t use compost or manure as a replacement for fertilizer. A healthy vegetable garden needs both. In addition to the compost recommended above, manure can be used instead of dry fertilizer. Manures vary widely in nutrient concentration and salt content, so take care to not apply too much. Compared with chemically formulated fertilizers, manures are a less precise method of fertilization because sources of manures vary greatly in nutrient and soluble salt content. A safe applica ...

Earth's largest recorded impact in history
|
view preview
The Tunguska event was a large explosion that occurred near the Tunguska River, in where is now Russia. The explosion occurred at an altitude of 5–10 kilometres (3–6 mi) by a stony asteroid that is believed to have burst in the air rather than hitting the surface. Since the 1908 explosion, there have been an estimated 1,000 scholarly papers (mainly in Russian) published on the Tunguska explosion. In 2013, a team of researchers led by Victor Kvasnytsya of the National Academy of Sciences of Ukraine published analysis results of micro-samples from a peat bog near the blast epicenter showing fragments that may be of meteoric origin. Estimates of the energy of the blast range from as low as three to as high as 30 megatons of TNT. The energy of th ...

Rainbows on fire
|
view preview
Fire rainbows are a rare phenomenon that only occur when the Sun is higher than 58° above the horizon and its light passes through cirrus clouds made of ice crystals. These captivating atmospheric displays are scientifically known as circumhorizontal arcs. While the name "fire rainbow" might suggest a connection with fire or rainbows, it's essential to understand that this phenomenon has nothing to do with fire and isn't a true rainbow. The process behind fire rainbows is intricate. When sunlight interacts with ice crystals in cirrus clouds, the light is refracted, or bent, in a specific way. For a circumhorizontal arc to form, the Sun must be at a relatively high angle in the sky, usually exceeding 58 degrees. This angle allows sunlight to e ...

What the media isn't telling you about war in Syria

I've been following the war in Syria quite a lot. It's overwhelming to see how little media coverage there is on what's really happening there. This video is most accurate according to my own research. Take a few minutes to watch it...

Before the iPhone and before the iPad, there was the Newton
|
view preview
The MessagePad, released in 1993, was the first in a series of Newton devices to be developed and sold on the market. The 1.4 pound physical device was collaboratively manufactured by Apple and Sharp. The MessagePad packed a 20MHz ARM 610 RISC processor, 640 kilobytes of RAM, and a 336x240 monochrome LCD touch screen with stylus and handwriting recognition support. It was powered by four AAA batteries. It ran Newton OS version 1.05 and cost $699.99. The Newton platform was axed from the Apple product line for two main reasons. (1) The early Newton OS that shipped with the original MessagePad proved to be not so user friendly, especially when it came to the unpredictable handwriting recognition software. The press and other media outlets (inc ...

Silence leads to madness
|
view preview
The anechoic chamber is located at Orfield Laboratory in Minneapolis, Minnesota and was designed for testing out hearing aid equipment. To make sure no outside noises are present, the chamber is hidden behind two vault doors and has sound-deadening wedges covering all of the flat surfaces. Rather than sound bouncing off the walls, ceiling, and floor like a traditional room, the sound is absorbed.

3D Imaging: A Practical Use of Mathematics
|
view preview
3D imaging used in dentistry. Once a panoramic x-ray is taken, the technician uses software to rotate the image; the software uses matrix mathematics to compute the position of the rotated image. One use for matrix math is in programming 3D engines for video games. A single point on the screen can be defined as a vector. The TV or computer screen is two-dimensional only, so to create the look of depth, objects must change size as they come closer to the viewer or go farther back into the scene. An image is made up of hundreds or thousands of vectors. By multiplying this set or matrix, you can change its size. You can also multiply the vector array by another array, which allows you to rotate the image. In rotation, parts of the image become ...

Finally, a video game where you build a cell, fight off viruses, and survive harsh worlds
|
view preview
CellCraft is a truly great flash game about building, controlling, and surviving as a human cell, viewed at the microscopic scale. I was surprised to find how accurate the game was, depicting organelles correctly and even conversion ratios of glucose to ATP. The game is a great primer for those who wish to learn some cell biology, or even for those of us who know plenty about the cell but want a refresher without cracking open a textbook.

Does your manager have a 'morning bias'?
|
view preview
A new study has shown that managers rate workers who get an early start higher than those who get in and stay later, no matter how good they are at their jobs, or how many hours they work in total. So, no matter what your boss says about flex-time, get to work early!

A Fruit You Won't Believe Contains MSG
|
view preview
Hidden within the vibrant red hues of a ripe tomato lies a secret that has excited taste buds and intrigued culinary experts for centuries. We're talking about monosodium glutamate, better known as MSG. While often associated with Chinese cuisine, MSG's natural presence in tomatoes adds a layer of complexity to the flavor profile of this beloved fruit (see vegetable). MSG is a naturally occurring compound found in various foods. This flavor-enhancing substance gained notoriety in the mid-20 th century when it was widely used as a food additive to intensify umami flavor – the so-called "fifth taste" that imparts a rich and savory sensation to dishes. MSG was originally isolated from kombu seaweed by Japanese chemist Kikunae Ikeda in 1908. Its ...

Is Nutella even healthy?
|
view preview
Imagine blending modified palm oil, skim milk powder, cocoa, hazelnuts, and whole lot of sugar – that's how Nutella is technically made. In fact, Nutella contains 10.4 percent of saturated fat and 58% of processed sugar by weight. A two-tablespoon (37-gram) serving of Nutella contains 200 calories, including 99 calories from 11 grams of fat (3.5 g of which are saturated) and 80 calories from 21 grams of sugar. The spread also contains 15 mg of sodium and 2 g of protein per serving. You're probably thinking, what if I gather up these ingredients and do it myself, will I have homemade chocolate spread? Not quite. Nutella uses modified palm oil rather than regular vegetable oil because it remains solid at room temperature. This modified oil i ...

The Secrets of Longevity: Exploring Okinawa, Japan
|
view preview
Have you ever wondered where people live the longest and healthiest lives on Earth? Look no further than the enchanting islands of Okinawa, Japan. Nestled in the East China Sea, Okinawa has gained international recognition for its high number of centenarians and remarkable longevity. Currently, there are 457 people in Okinawa aged 100 or over, an average of 35 for each 100,000 inhabitants. While Japanese people generally live longer than any other nation, the Okinawa inhabitants reach ages that take by surprise even the other Japanese: an average of 86 for women and 78 for men. One of the key factors contributing to the longevity of Okinawa's residents is their traditional diet. The Okinawan diet is rich in plant-based foods such as sweet po ...

McDonald's will never be the same again

I know this is a science blog, but hear me out. I'm not sure what sort of stunt McDonald's is pulling here, but apparently they are removing the world famous Big Mac off their menu. Currently, the Big Mac has a whopping 550 calories and 29g of fat. It's probably the only reason I ever go to McDonald's, so I guess from now on it's going to be the Whopper instead. ...

The cost of water in the Middle East
|
view preview
If you live in North America, you've probably never given the cost of water a second thought. In fact, you've probably taken its value for granted probably because it costs very little or because it's vastly abundant. In places like Saudi Arabia, however, a liter of water costs five times as much as a liter of gasoline. This is because much of the water in Saudi Arabia is seawater that is purified in desalinization plants ( Al Jubail desalination plant shown above). This price relative to fuel is quite different in the United States. For example, a liter of water (from a tap) is virtually free, while a liter of gasoline is around $0.75 (about $3.00 per gallon). As a result of this significant difference in cost, it plays a major effect on hu ...

How Selective Breeding is Used in Behavioral Genetics
|
view preview
One of the methods used by behavioral geneticists is selective breeding. Selective breeding often involves selecting animals that are very different on one measure of behavior. For instance, if scientists take 20 rats and test how quickly they can solve a maze, chances are that they will get some variability in the speed with which the rats can solve the maze. Scientists would take the two fastest animals and the two slowest animals and breed them together. They would continue to do this over 20 generations, until they had a group of animals that solved the maze very rapidly and a group of animals that solved the maze very slowly. They are then able to examine potential differences in their brains and behaviors that contribute to maze solvi ...

Types of Fallacies in Reasoning
|
view preview
We often have lapses in critical thinking as we speak and write. A fallacy is a belief or argument that rests on invalid or false inference that is logically unsound. Fallacies are often used unintentionally, but they are also used intentionally when an effort is being made to deceive or mislead the listener or reader. 1. "If you know about BMW, you either own one or you want one."What's wrong with this statement? It is an example of the fallacy called false alternatives. It is also called dualistic or black-and-white thinking and bifurcation. The fallacy occurs when it is presumed that a classification is exclusive or exhaustive. It often takes the form of overlooking alternatives that exist between two polar opposites. Here is another examp ...
