How To: Safely Put Out a Grease Fire (And Prevent Them Altogether)

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 ...

How To: Clever Chemistry-Based Cures to Common Kitchen Conundrums

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.

How To: Turn a Pint of Ice Cream into a Freakin' Loaf of Sweet Bread

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...

How To: Make Your Own Twinkies and CupCakes (Now That Hostess Is Closed Down)

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...

How To: Derive the area of triangle using trigonometry

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...

How To: Change a Phone's Coordinates by Spoofing Wi-Fi Geolocation Hotspots

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.

How To: Exploring Kali Linux Alternatives: How to Get Started with Parrot Security OS, a Modern Pentesting Distro

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.

How To: Exploring Kali Linux Alternatives: How to Get Started with BlackArch, a More Up-to-Date Pentesting Distro

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.

News: Natural Antibiotic from Cystic Fibrosis Patient Knocks Out TB

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.

News: Compound in a Frog's Defensive Slime May Treat Your Next Flu Infection

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.

News: Livestock Antibiotic Use Increases Threat of Resistant Microbes to Humans

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.
