I love pomegranates. I don't even mind the mind-numbing task of picking out the arils (which is what those ruby-colored seed-like things in the pomegranate are called). However, I'm always on the lookout for new, easy ways to peel it that don't make my kitchen look like a crime scene.
Despite its deliciousness, the pomegranate is one of the hardest fruits to eat. Once you cut it open, the seeds are stuck behind a bitter-tasting white membrane, and trying to pull them out with your fingers just results in a huge mess.
We've all seen the classic tornado-in-a-bottle science experiment, which uses 2 two-liter bottles to create a whirlpool effect. This version requires you to get the tornado started yourself by spinning the bottles, but what if you want to make it fully automated?
Ever see those cars so covered in dirt, dust, and grime that someone writes "Wash me" on it using their finger? Well, for those cars' sakes, as well as cases less extreme, a word of advice: procrastination is not a solution — it can only compound the problem. Self-cleaning cars are the stuff of the future, not the present, and your car needs attention now.
We've all played with bubbles as kids, but I think most would agree that they're not exactly the most functional of objects. An international team of researchers made up of Yoichi Ochiai, Alexis Oyama and Keisuke Toyoshima wants to change that. They've figured out how to project both 2D and 3D images onto a micro membrane (soap bubble) using ultrasonic sound waves and a standard projector. The bubble is made of a solution of sugar, glycerin, soap, surfactant, water and milk. The glycerin and ...
All fields of study have their own language. For people interested in learning about microbes, the language can sometimes be downright difficult — but it doesn't need to be. From antibiotics to xerophiles, we have you covered in an easy-to-understand glossary.
The rate of preterm birth has been increasing in the United States for unknown reasons, causing increased health risks for infants born too soon. But researchers may have found a signal that could help doctors plan ahead for, or even prevent, early birth with a simple swab of the vagina and cervix during pregnancy.
Some bacteria can already do it—generate electric current, that is—and those microbes are called "electrogenic." Now, thanks to the work of a research group from the University of California, Santa Barbara, we know how to easily turn non-electrogenic bacteria into electricity producers.
When it comes to proper tomato storage, conventional kitchen wisdom (and Alton Brown) state that tomatoes are best stored at room temperature—not in the refrigerator. Supposedly, refrigerated tomatoes develop a mealy texture and lose their flavor if they are exposed to cooler temperatures over time.
Is it possible to cut or chop onions in the kitchen without stinging eyes and looking as if you just watched the saddest movie ever? Before we get to that answer, it's important to know why we tear up when cutting raw onions in the first place. What is this irritant? Are you reacting to the odor? The answer to the latter question is "no," and the irritant responsible is amino acid sulfoxides.
A vaccine against HIV might prevent the disease that we can't seem to cure. Some HIV patients make antibodies that can take down the virus, much the way a vaccine might. But, scientists haven't been able to provoke that type of response in other people. However, in a process that might work in humans, a group of researchers has successfully generated antibodies in cows that neutralize multiple strains of HIV.
Urinary tract infections (UTIs) drive over eight million people to seek medical attention every year. Almost all — as many as 90% — of those infections are caused by Escherichia coli. Copper can kill bacteria, but E. coli has found a way to capture the copper, preventing its antibacterial action. Now, researchers have found that, in a cruel irony, the bacteria use the copper it grabs as a nutrient to feed its growth.
Scientists know that bacteria create their own energy, get nutrients to run their cellular processes, and multiply. But, bacteria haven't been shown to respond to external mechanical stimulation or signals in a way that's similar to how our bodies respond to touch, until now.
Not all bacteria in the eyes cause infection. A group of researchers from the National Eye Institue has shown that not only is there a population of bacteria on the eyes that reside there but they perform an important function. They help activate the immune system to get rid of bad, potentially infection-causing — pathogenic — bacteria there.
HIV infections persist despite treatment that successfully decreases viral blood levels to the point where doctors can't detect the virus. But that doesn't mean the person is cured. The virus hides in the body, not replicating, just waiting for a chance to jump out of the shadows and reemerge.
The problem with HIV is that it attacks and kills the very cells of the immune system that are supposed to protect us from infections — white blood cells. But a new technique, developed by scientists at The Scripps Research Institute (TSRI) in La Jolla, California, offers a distinct HIV-killing advantage.
Breastfeeding is the ultimate in farm-to-table dining. It is sustenance prepared just for the baby and delivered with a very personal touch. Along with bonding, breastfeeding provides powerful protection to infants and young children in the form of beneficial bacteria, hormones, vitamins, protein, sugar, and antibodies manufactured on site to support infant health.
I record close-cropped videos and take macro still shots with my smartphones on a daily basis, so as you would expect, I spend a lot of time cleaning these devices. Over the course of a couple years, I've fine-tuned my cleaning regimen, and at this point, it's down to a near-science.
More prescriptions for antibiotics are written for ear infections than any other type of infection. A new study comparing the incidence and causes of ear infections in children between the ages of six months and three years found that the incidence of ear infections over the last decade has dropped significantly since the 1980s.
Infections with group A streptococcus, like Streptococcus pyogenes, claim over a half million lives a year globally, with about 163,000 due to invasive strep infections, like flesh-eating necrotizing fasciitis and streptococcal toxic shock syndrome.
In the perpetual search for a renewable and convenient energy source, our bacterial friends have once again stolen the limelight.
Cats give us so much—companionship, loyalty, love... and now the bird flu. Several weeks ago, a veterinarian from the Animal Care Centers of New York City's Manhattan shelter caught H7N2 from a sick cat. According to a press release from the NYC Health Department on December 22, "The illness was mild, short-lived, and has resolved." This isn't the first time cats have passed infections on to humans, but it is the first time they passed on the bird flu—avian flu H7N2, to be exact.
Knowing if your meat is cooked properly is both the difference between a delicious meal and an inedible one... and the difference between making your guests sick and keeping them safe.
Eggs are incredibly important to cooks, and not just because they're tasty and a complete protein (many erratic genius/artist types make a point of eating an egg or two for breakfast). Yes, they are great when perfectly poached, scrambled, hard-boiled, and even scram-boiled, but they serve literally dozens of functions when used in recipes, especially baked goods.
Brining is magic. All you have to do is make a mild saline solution, toss in your protein of choice, let it soak, and cook. You end up with incredibly tender, flavorful meat or tofu for very little effort. So why aren't more of us doing it?
Hard-boiled (also known as hard-cooked) eggs are notoriously easy to mess up. We've all ended up with tough, rubbery egg whites and overcooked yolks that have that unappetizing gray-green ring around the edge. An ideal hard-cooked egg has a firm yet tender white, while the yolk is creamy and well-done without being mealy.
When Steve Jobs introduced the first iPhone, he pointed out that the biggest problem with physical keyboards on mobile phones is that they're always there, whether you need them or not. Now, 17 years later, a new company is bringing us full circle, giving us the best of both worlds: a physical keyboard for iPhone that can disappear whenever you want.
The Pi-hole project is a popular DNS-level ad blocker, but it can be much more than that. Its DNS-level filtering can also be used as a firewall of sorts to prevent malicious websites from resolving, as well as to keep privacy-killing trackers such as Google Analytics from ever loading in the browser. Let's take a look at setting a Pi-hole up and customizing a blacklist to suit your needs.

The latest culinary trend? How about breaded and fried deer balls. That's right, you heard me. The Atlantic makes an interesting point about the political correctness of "nose-to-tail" eating:
A membranophone is any musical instrument which produces sound primarily by way of a vibrating stretched membrane. This 3 part how to video teaches you how you can make an inexpensive mebranophone made from household items. All you need is a water bottle, a latex glove or vinyl glove or a balloon, and a straw. Learn how to make this fun musical instrument with this tutorial. This project is perfect for children. Construct a membranophone from a water bottle - Part 1 of 3.
Experimental house, "Roll It", is a collaborative project within Germany's University of Karlsruhe. The basic concept is as follows: using a cylindrical design to maximize space within a minimum housing unit. Not sure how "space efficient" this would actually be, but using it as transport could be fun (until the nausea inevitably sets in).
I first heard the term molecular gastronomy while watching an episode of Bravo's Top Chef a few seasons back. Intrigued by the concept, I sought to find out more about this modern, deconstructed type of cookery. If you happen to be around foodies and the topic of molecular gastronomy comes up (which very likely will at some point) you'll want to have a few points to contribute and maybe even give them a run for their money.
It's not uncommon for nature to inspire technology and innovative products. Airplanes were inspired by birds, Velcro by burrs and dog fur, bullet trains by owls and kingfishers, and gecko tape by... well, you can probably figure that one out. And one of the deadliest fish ever to swim the oceans has also influenced its share of merchandise; Sharks made humans faster in the water with Fastswim Suits, and now they've helped make one of the most rugged smartphone cases in the world—SharkEye's Ru...
Welcome back to the two-part series of Ten foods to eat for clear, acne-free skin. Check out part 1 here.
You can blame your naggy mom, a crappy soap bar, and school or work stress for your acne. But ultimately, you should blame yourself. While it's true that your skin type (oily vs. dry vs. sensitive) and how your skin reacts to stress play a big part in blemishes, there is a nurture component to this argument.
