Find out how everything in a chemistry lab works, from pipettes to burners to recrystallization to storage. You'll get precise instructions on how to work and perform certain scientific duties in the chem lab, whether it's chemical or just ordinary high school science.
It's common knowledge that when it comes to your child being happy and successful in life, giving them access to an excellent education is paramount. Whether your son or daughter grows up to be an engineer or an artist, they should be well-rounded in a wide range of diverse disciplines to take advantage of all the opportunities that will inevitably come their way.
Let's say you're using your iPhone's Calculator app, and you're knee-deep into a complicated calculation with many steps. You type in a large number, for example, "123,466,789," but mess up. You meant to type "5" midway through but accidentally typed "6" instead. The only thing to do now is start over, no matter how far along you are, right? Wrong.
This is a tale about microbes, a man who became a hermit, and the parchment that carries both of their stories.
When the climate changes, so do all the things that rely on the climate, including people, plants, and pathogens. A European study recently took a broad look at what kind of microorganisms are most likely to be affected as climate change heats, cools, dries, and wets the world around us.
Forget the rise of the machines. Tardigrades are set to outlive everything — even the bots. When the last echo of a whisper in a cell phone has long dissipated into space, the water bears will still be hanging out.
For a company more associated with debugging computer programs, Google's parent company, Alphabet, is making a name for itself by taking on the real thing — mosquitoes.
Colorectal cancer — cancer of the colon or rectum — is the third most commonly diagnosed cancer in the US. To reduce the chances of a diagnosis we are all urged to stop smoking, keep our weight down, decrease our intake of alcohol and red meat, keep active, and get screened for colon cancer. But, new research has found something that participates in the development of colorectal cancer that might not be as easy to control: A strep bacteria that promotes tumor growth.
A new study casts real suspicion on the possibility of life on Mars. Why? It seems the surface of the planet may be downright uninhabitable for microbial life as we know it.
Dengue fever is a danger to anyone living or visiting tropical or subtropical regions. It can be hard to detect the infection in its earliest and most treatable phase, especially in children. Luckily, new research highlights better techniques for triaging the disease in infected children with more severe symptoms, potentially saving lives.
Fighting fire with fire, scientists are harnessing the adaptability of helpful microbes to challenge the adaptability of deadly microbes. What are we talking about? Hunting with phages — viruses that attack and kill bacteria.
Being infected with HIV means a lifetime of antiviral therapy. We can control the infection with those drugs, but we haven't been able to cure people by ridding the body completely of the virus. But thanks to a new study published in Molecular Therapy by scientists at the Lewis Katz School of Medicine (LKSOM) at Temple University and the University of Pittsburgh, all that may change.
On October 17, 1943, a story in the New York Herald Tribune read "Many laymen — husbands, wives, parents, brothers, sisters, friends — beg Dr. Keefer for penicillin," according to the American Chemical Society. Dr. Chester Keefer of Boston was responsible for rationing the new miracle drug, penicillin.
Our quest to find new antibiotics has taken a turn — a turn down the road, that is. A team of scientists from the University of Oklahoma is scooping up roadkill and searching for bacteria on them that might yield the world's next antibiotic.
An outbreak of anthrax from contaminated meat in Tanzania sickened dozens of people and moves the danger of this deadly bacteria back into focus.
A gold-medal winning entry into the iGEM synthetic biology competition could change the way we look at Esherichia coli, the bacteria better known as E. coli.
I'm sure I'm not the only one on here that has googled "Why am I always tired?"... and I'm definitely not alone when I say that all of the advice I've found so far is useless:
The sprouts, they're alive! Alive, I tell you—aaaaaaliiiiiive! (Cue dramatic music.) It's true: sprouts are a living food, and they're packed with more nutritional benefits than some raw vegetables. It's easy and fun to grow your own sprouts from seeds, legumes, and grains. Plus, watching them grow is incredibly satisfying—you're bringing new life into the world (and onto your plate)!
Caramel is delicious, but it can be a tricky flavor to incorporate into baking. Traditionally, caramel is a liquid, and that doesn't always suit dessert preparation since adding extra liquid to baked goods can ruin them. So how do you get that buttery, toffee-like flavor?
Hanukkah, also known as The Festival of Lights, commemorates the rededication of the temple in Jerusalem in 168 BCE. (Jews and secular publications, such as academic or scientific papers, use BCE—"before common era"—rather than the Jesus-centric BC, or "before Christ.")
3D Touch is a new feature on the iPhone 6S and 6S Plus that's reinventing the way we interact with our smartphones. With just a little bit of added pressure when tapping on the display, you can perform Quick Actions from an app's home screen icon, "Peek" at emails, stories, and photos in-app, as well as perform other app-specific gestures. Since 3D Touch is such a new concept, here are some of the apps that currently support it, along with the shortcuts you can use.
Preparing and serving seafood can be a daunting task. Fish is so delicate that one extra minute of heat can turn a juicy, flaky filet into a dried-out disaster. But that same fragility also allows us to use unconventional methods to chemically transform the fish into its cooked consistency.
Any beer aficionado who's been to Ireland will always talk about how the Guinness there "just tastes different." But save your eye rolls, skeptics: it turns out your favorite lagerhead actually has a valid point.
Cheese might be one of the most satisfying snacks around, whether you prefer a slice of snappy Irish cheddar or a creamy, rich portion of Brie. It's been called "dairy crack" by a respected physician and for good reason: eating cheese produces casomorphins, which effect the human body like opiates. It also contains trace amounts of actual morphine.
Willpower is a pretty significant word. It's the difference between sticking with a clean eating diet and diving face-first into a plate of brownies. It's what drags you out of bed on Monday mornings and into work rather than letting you stay snuggled under the covers asleep. And, most importantly, it's the kick in the butt we all require to both accomplish goals and make changes.
There are so many cutesy pink, red, and heart-shaped desserts and drinks put out on Valentine's Day, but none of those really get you into a low-light mood. Instead, turn up the heat with one of these aphrodisiac cocktails for grown-ups.
Certain ingredients that a professional chef might work with in a restaurant-style setting may seem bizarre, dangerous, and even downright scary to a home cook, and for good reason.
Bottled water is a rip-off. Not only is it pretty much the same stuff that comes out of your tap for free, but plastic bottles are rarely recycled and thus account for a huge amount of the waste that's overflowing our landfills. Next Up: Water Bottles You Can Eat
You've been there. Those precarious few seconds between dropping your expensive smartphone right on its face and reaching down to survey the damage. Or maybe you got thrown in a pool while your device was in your pocket, or you dropped that sucker right into the toilet bowl. Heck, I've managed to accidentally wash two devices by leaving them in my pants pocket when throwing in a load of laundry.
Religion is one of the most-ignored topics when it comes to Steampunk, which is surprising given how important religion was in Victorian England. Even the hot-button issues of race and gender are confronted with a greater awareness than religion.
There's only three weeks left until the spookiest holiday of the year, which means stores and costume shops everywhere are bringing out their Halloween inventory full force. So now's a good time to start prepping your Halloween costume—because you really don't want to do it last-minute again, do you?
Introduction So today and yesterday I was playing with TNT (as we all do at one point or another) and I was curious about a few things. From this curiosity, I went on to discover some of the science behind some things you may or may not have known.

Pronunciation is key to learning any new language. Before diving into the vocabulary and basic phrases, a good approach is to listen and try and get your aural perception honed in. A new word or phrase, like "je m'appelle" in French, is awesome to learn, but it's important to learn it correctly: that starts and ends with pronunciation.
Remember Brian sticking a 4-inch nail up his nose at Diggnation New York? Want to do it yourself? This time he shows you how it works!
If you're using a mobile device, it's a pretty safe bet that your apps are sending lots of information back and forth from their servers. To make sure there is no inappropriate data collection going on, it's worth setting up a web proxy to spy on this traffic, so you know exactly which apps are "phoning home" and when.
The holidays are stressful. Between traveling, family, and dinner, Thanksgiving weekend can feel like weeks. Many families have traditions that make the days long, but some of us would rather curl up somewhere and watch our favorite shows. But all is not lost — our phones do so much for us now that they can help make the long stressful weekend much more bearable.
If you use the Google Assistant on your Android device, you can easily send a text message to any one of your contacts. But even though that same Assistant is powering the Google Home, you can't use the smart speaker to accomplish the same task — at least, not without some tinkering.
One of Android's biggest strengths, when compared to other mobile operating systems is its open file structure. Google introduced a built-in file manager with Marshmallow that provides basic file management, but like with most apps on Android, there are alternatives. Third-party file managers are readily available, providing deeper access and control of all your files.
