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 ...

Nipping Common Gardening Mistakes in the Bud
|
view preview
Some people are born with a green thumb – they need only pick up a watering can to make their gardens teem with brilliant flowers and vegetables. To the rest of us, gardening comes less naturally. And for some people, it’s a complete and utter mystery. But growing productive, vivacious plants doesn’t have to be hard. 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. Roots in waterlogged soil cannot breathe; as a result, plants wilt, turn yellow, rot, and die. Follow a few simple rules of thum ...

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 ...

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. These Foods... | Are Risky When: | Fresh poultry | - stored raw in the refrigerator for longer than 1-2 days, (3-4 days for cooked poultry)

Five Common Eye-Related Conditions and Diseases
|
view preview
Try imagining for a second how it'd feel to lose your eyesight. It's almost unimaginable because your vision is perhaps the most valuable tool for survival. This is why we need to constantly protect our eyes and learn what could potentially ail them. Below is a list of five common illnesses that plague the precious eyes of people around the globe. GlaucomaGlaucoma is damage to the optic nerve, often caused by elevated intraocular pressure. It results from excessive production of aqueous humor or diminished ocular fluid outflow. Glaucoma is a leading cause of blindness, secondary to optic nerve damage. As of yet, there is no cure. Everyone is at risk, and there may be no warning signs. It is six to eight times more common in African Americans ...

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 ...

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 ...

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 ...

Want to relive the 90's? This emulator let's you use Windows 95 on your browser
|
view preview
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. It provides you with a full Windows 95 operating system and e ...
