Even the best-maintained kitchens occasionally get a fruit fly infestation. These critters descend, lay eggs (up to 500 at a time!), and then disappear usually only after extreme cleaning efforts (i.e., finally attacking that weird puddle of goo behind your refrigerator).
When I became serious about cooking, nearly every cookbook and guide I picked up emphasized the importance of using fresh stock, whether it was chicken, beef, or vegetable. When I didn't have time to make my own, I bought the highest quality boxed or canned stock I could find at the market.
If you're a Febreze fanatic, you're well aware that the "odor eliminator" can be pretty pricey, and that's reason enough to stop buying it.
Hopefully you never have to deal with a grease fire, but if it happens, how you handle it is important. A grease fire isn't like a regular fire, and trying to put it out the same way can make it worse. Grease fires are caused by letting oil get too hot, so the best way to prevent them is to never leave your kitchen unattended. Oil smokes before it burns, so if you see your pan start to smoke, take it off the heat before it has a chance to catch fire. If you're outside grilling, you can add a ...
Mashed potatoes are universally beloved, and for a good reason — they're cheap, tasty, and relatively easy to make. What's more, they're adaptable to just about every dietary regimen, whether you're vegan, gluten-free, or lactose-intolerant. And they're a staple for holidays such as Thanksgiving.
You probably already know that cooking involves a ton of chemistry. Bread rises because of the reaction between the flour and leavener, and the delicious crust on your steak is formed by the Maillard reaction. Understanding the chemistry going on behind the scenes is one of the best ways to improve the quality of your food—it's much easier to fix a problem when you know what's causing it.
Cooking may be an art, but baking is a science. It requires precise measurements since the outcome is based on chemical reactions. Using too much or too little of one ingredient can be the difference between perfect, crunchy-yet-chewy cookies and the dreaded "one big cookie." That's why frozen cookie dough and pre-made bread and cake mixes are so popular. They're easy to throw together, and pretty much guarantee success every time. But what if you're feeling so lazy that you don't even want t...
If you have an oil stain on your asphalt driveway, wipe up the excess oil with an absorbent cloth or mop it up, then act quickly using the common household items below to make sure that it doesn't become a permanent eyesore or a headache to clean up later.
As a kid, I remember hearing the myth that Twinkies could last forever. The rumor was that they were made from chemical ingredients that caused the Twinkies to stay fresh and edible for years and years. Right along with the cockroach, Twinkies were supposed to be the only survivors of the nuclear holocaust that would destroy the entire world. As I got older, I realized the rumor wasn't true. Twinkies actually have a shelf life of just 25 days. And with the news that Hostess is going out of bu...
This is an awesome little science trick that has to be seen to be believed. Simply by emptying a bottle of "supercooled" water into a glass, you can watch it turn into ice right as your pour! It's no magic trick or chemical craziness—it's normal water and you can try it yourself right in your own home.
This video teaches the method to find the area of triangle using law of cosines and law of sines together with the area formula. Law of cosines is used when you have the length of three sides. It states that the square of side 'a' is equal to addition of the squares of sides 'b' and 'c' minus the product of 2, b, c and cosA. The values of sides are substituted and angle A is found. This is substituted in the area formula which states that the area of a triangle is equal to the half of the pro...
Want to find out how you can squash a can of Coke with a little science? Just watch this video tutorial to see how to crush a soda can with heat and cold water. You will need to get an empty can of Coke (or Pepsi if you prefer) with a little water inside, something to hold the soon-to-be-hot can with, a bowl, ice, water and salt. You can impress your friends with this trick, all without using your own force... a little chemical and temperature change goes a long way.
Unless you're a high-schooler building a nuclear fusion reactor, the hardest part of a science investigatory project often is coming up with a good idea. You want it to be cool yet feasible, novel but still useful.

In many urban areas, GPS doesn't work well. Buildings reflect GPS signals on themselves to create a confusing mess for phones to sort out. As a result, most modern devices determine their location using a blend of techniques, including nearby Wi-Fi networks. By using SkyLift to create fake networks known to be in other areas, we can manipulate where a device thinks it is with an ESP8266 microcontroller.
Kali Linux is the obvious first choice of an operating system for most new hackers, coming bundled with a curated collection of tools organized into easy-to-navigate menus and a live boot option that is very newbie-friendly. But Kali isn't the only distribution targeted at pentesters, and many exciting alternatives may better fit your use-case. We've already covered BlackArch Linux, now it's time to talk about Parrot Security OS.
In 2013, Offensive Security released Kali Linux, a rebuild of BackTrack Linux derived from Debian. Since then, Kali has gone on to become somewhat of a standard for penetration testing. It comes preconfigured with a collection of tools accessible by a menu system, tied together with the Gnome desktop environment. However, Kali Linux isn't the only penetration-testing distribution available.
Over the past year, Magic Leap has teased its cross-platform vision of the AR cloud, which it dubs the Magicverse. While the company shared a timeline for its debut next year, it also served up new developer tools for the present.
Just like Apple and Google, Facebook has been working to develop computer vision shortcuts designed to give mobile apps augmented reality superpowers.
The company behind augmented reality's first real gaming hit, Pokémon GO, is quietly making moves toward supporting the rapidly growing smartglasses space that may one day move its content away from smartphones and tablets and onto AR lenses positioned on your face.
Now that we've had a chance to jump into the Lumin SDK documentation at Magic Leap's Creator Portal, we now have much more detail about how the device will function and utilize software than any single piece of content released by Magic Leap to date.
The bacteria in our gut — a community called the gut microbiome — have been in the spotlight a lot lately. What we're learning about how our intestinal bacteria adapt and grow with our bodies could help athletes perform better, according to researchers starting a company focused on creating probiotics that mimic athletes' microbiomes.
After watching Samsung's exploding phone fiasco this past year, I took comfort knowing that the likelihood my iPhone would suddenly combust was slim. However, after hearing about a recent incident in Wisconsin, iPhone owners may have reason to worry.
When you think about preparing for an internship, I'm sure your first thought is to go shopping for professional outfits or to brush up on technical skills. While that's all important, there's so much more for you to think about.
Everything from disposed of drugs to hormones and disease-causing bacteria — anything that is rinsed or flushed down the drain — can contaminate wastewater.
A promising new antibiotic has been discovered in, of all things, another bacteria. Burkholderia bacteria live in diverse habitats, including soil, plants, and humans where they thrive by knocking out other microbes that compete with them for resources or threaten their existence. Scientists have discovered they accomplish this by producing a very effective antibiotic.
The evidence is mounting and is becoming indisputable: Gut bacteria play a role in strokes and heart attacks. The link may seem a little far-fetched, but cardiovascular disease may have less to do with what we eat and more to do with what chemicals gut bacteria make from the food we eat.
What would it be like to have clothing that killed microbes? Or paper that repelled pathogens? A research team from Rutgers University has developed a prototype out of metalized paper to zap the bad guys without being super expensive. Sound good? Read on.
Sometimes it's impossible to concentrate — let alone direct your personal assistant Siri — when someone is blasting music on their phone or talking to thin air. I mean I'm loud, but not that loud.
The body's usual response to a bacterial infection in the blood — called sepsis — takes time. It requires a carefully orchestrated sequence of events that gets the body's immune system ramped up to deal with the invading bacteria.
While it is easy to create and maintain your compost pile, you can enjoy it more knowing a few basic tips.
Electrical impulses course through our heart and keep it beating. That's why a jolt from an automated external defibrillator can boost it back into action if the beating stops. But new research says there may be more to keeping a heart beating than just electrical impulses.
Our quest to find novel compounds in nature that we can use against human diseases —a process called bioprospecting — has led a research team to a small frog found in India. From the skin slime of the colorful Hydrophylax bahuvistara, researchers reported finding a peptide — a small piece of protein — that can destroy many strains of human flu and can even protect mice against the flu.
Antibiotics used to prevent diseases in livestock are creating a world of hurt for humans and the soil we depend on for food. Bacterial resistance to antibiotics is a global health issue. The overuse, underuse, and poor use of these life-saving drugs is rapidly removing them as a treatment option for serious infections in humans—plus bacteria are naturally adaptive.
When it comes to global warming, most of us think of carbon dioxide emissions. While carbon dioxide is the most important greenhouse gas, carbon dioxide emissions have stayed constant for the last three years. On the other hand, methane, the second most important gas, has been steadily rising since 2007.
