There are tons of ways to make a macro lens for your smartphone, but if you need one for a DSLR, it's not quite as simple as using a magnifying glass or a drop of water. If you have an old kit lens, though, you can turn it into a macro lens in no time—all you have to do is remove the front element. For this hack, Juha Loukola over on PetaPixel used a Canon 38-76mm lens, but says that the process should be pretty much the same for other lenses.
If you use apps on your smartphone, chances are you have no idea what those apps are doing with your information. Just this year, there have been several scandals involving apps transmitting user data, like Path uploading users' entire address books onto its servers, HTC's Security Flaw, and Brewster exposing users' personal information (even Ashton Kutcher's). A new service called Mobilescope wants to make sure you always know where—and to whom—your data is going. Lots of apps copy your cont...
This tutorial by the Floral Design Institute demonstrates how to create a hand-tied Calla bridal bouquet. The key to creating this bouquet is to make sure your flowers are properly prepared. The flowers should be fully hydrated (in water for at least two hours). Take each flower and mold each stem to to reflect the natural curve of the flower. Lay them side by side so they are lined up in a parallel fashion. Give even pressure on the stem to prevent bends or kinks. Some stems may be straight ...

Hey, you, still stuck at home? Cheer up, today is the first day of spring. Yes, really. And since you're probably locked in on TV, we're guessing you need a break from some of the less than sunshiney news reports rolling in. Well, no worries, because there's actually some good news to report.
Google is an incredibly useful database of indexed websites, but querying Google doesn't search for what you type literally. The algorithms behind Google's searches can lead to a lot of irrelevant results. Still, with the right operators, we can be more exact while searching for information that's time-sensitive or difficult to find.
Nowadays, our phones are capable of just more than 30 fps video. Phones like the Galaxy S10 can shoot 4K at 60 fps, even on the front camera. Slow motion functionality has recently started to appear on more and more devices — but as you may have noticed, the quality of the feature differs from phone to phone.
Two companies armed with web-based augmented reality tools, Vertebrae and Shopify, are ready to help online retailers boost their sales.
On the airplane, in the middle of cold and flu season, your seatmate is spewing, despite the clutch of tissues in their lap. Your proximity to an infectious person probably leaves you daydreaming (or is it a nightmare?) of pandemics and estimating how likely it is that this seatmate's viral or bacterial effusions will circulate throughout the plane and infect everyone on board.
Flu vaccines can help prevent us from getting or suffering the most severe effects of the flu. But, each vaccine only protects us from three different strains of the flu. If we don't have a vaccine against all types of flu, it leaves us open for an epidemic with a flu virus we didn't expect.
Nineteen days ago, several hundred people could have been exposed by a traveler with measles in Nova Scotia, Canada. The next day, someone flying from Minnesota to Nebraska may have spread the measles to other passengers. A couple weeks ago, it's possible that a man and his six-month old child spread the measles in several Seattle-based locations. Authorities are trying to locate persons who may have been in contact with these people. None of the persons with measles were vaccinated. Why?
I'm not ashamed to admit it: I love Gatorade. It's probably from all of those times I watched Michael Jordan chug it during basketball games when I was a kid. But I'm not the only one that loves Gatorade—a large percentage of people who work out regularly choose to replenish their electrolytes with sports drinks.
It's truly amazing how far smartphone camera hardware has come in such a short period of time. It took roughly 5 years to advance the image processing capabilities from a pixelated mess to the crisp and clear photos we can take today. This reaches well beyond the megapixel spec race, since camera modules these days sport vastly improved optics, wider aperture, and even larger pixel sensors that capture more light.
Living in Los Angeles has given me the opportunity to attend a bunch of really cool events. I've been to Dodgers, Lakers, and Clippers games, a few concerts at the Staples Center, and a plethora of smaller joints.
Links of Love is showing you how to make origami heart shaped cuff-links. Start with a 20.5 cm square of paper. If you want to make a cuff link you can wear you should use a square the size of 4 to 5 cm. Fold a good crease and then unfold. Fold two corners in toward the middle and then unfold. Fold one side in toward the middle crease. Only crease up to the crease of the corner fold. Unfold and fold the side into the new crease just made. The creases are guidelines that will be used later on ...

Bill D., the tech lead at all3sports.com takes us through the steps involved in unpacking and assembling a brand new bicycle. The first he says is to set up or insert the seat post. He recommends using a work stand if you have one at home. He says not to unpack everything at the beginning, but to just expose the seat pack first. Use a wire-cutter to get rid of the film protection used for packing. He has mounted the frame-set on the work stand. The seat post goes into the frame-set. He asks t...
Would you know what to do if someone ingested poison? Equally important, would you know what not to do?
Each year, Apple seems to design its devices to be more difficult for owners to repair themselves. So when an iPhone breaks, a trip to the Genius Bar or an Apple Authorized Service Provider is most likely necessary. But if you have an iPhone X that needs a new battery, a leaked video just spilled the beans on how to replace the battery precisely as Apple would.
With all the web applications out on the internet today, and especially the ones built and configured by novices, it's easy to find vulnerabilities. Some are more perilous than others, but the consequences of even the slightest breach can be tremendous in the hands of a skilled hacker. Directory traversal is a relatively simple attack but can be used to expose sensitive information on a server.
Unfortunately, the very places we go to receive health care put us at risk for becoming infected with superbugs, bacteria exposed to so many antibiotics that they have become immune to their effects. Clostridium difficile (C. diff) is one such bacteria. It causes inflammation of the colon and rampant diarrhea that can have life-threatening consequences. Part of its virulence lies in the tough spores formed by the bacteria. They are responsible for starting infections in the colon and for spre...
Once we recover from the respiratory infection pneumonia, our lungs are better equipped to deal with the next infection — thanks to some special cells that take up residence there.
The herpes simplex virus (HSV) can cause devastating complications for infected newborns whose mothers have genital herpes. Understanding risk and research can help you, and your baby, when the time comes.
More bad news for patients who have undergone heart surgery in the past five years. A new study suggests about one-third of heater-cooler units used in cardiac procedures remain contaminated with a slow-growing, potentially fatal bacteria.
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.
Legionnaires' disease is named after 1976 outbreak in Philadelphia that sickened 221 people and killed 34. More often striking adults over the age of 50, the Centers for Disease Control and Prevention (CDC) recently reported two cases where newborns contracted the often fatal disease — at their moment of birth.
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.
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.
Even as health authorities describe the symptoms of Zika infection in the general population as mild, a new surveillance study finds serious side effects are more common, and serious, than previously thought.
Even if your cat drives you a little nuts, don't worry, because a new study says that cats pose no risk to your mental health.

Last month, it was revealed that Juniper Networks' routers/firewalls were hacked. It was reported that a backdoor was implanted in the operating system of their routers/firewalls and that attackers could listen in on all encrypted communication. There are now fears that all confidential communications by U.S. government agencies and officials could have been compromised over the last three years.
Dulce de leche is a beautiful, caramel-like spread that you can slather onto bread or use to flavor cakes, cookies, or flan. You can also use it as a drizzle for ice cream, chocolate candies, and pastries. It tastes like heavenly toffee, translates roughly to "milk candy," and is popular all over Latin and South America. A version of the confection is also popular in the Philippines, in Russia, and is known in France as "confiture de lait." The traditional way to make dulce de leche is to slo...
