The Department of Biological Sciences at the University of Alberta brings you this video tutorial specifically relevant to your student laboratory courses, specifically microbiology. If you're a student at any school of biology, this information will be helpful for learning how to use the Spectronic 21 visible spectrometer in the lab.
To keep fungal pathogens at bay in their crowded homes, wood ants mix potions to create powerful protection for their nest and their young.
You may or may not have heard the term "greebles" or "kit-bashing" before, but if not, they may sound like nonsense. Particularly 'greebles', which sounds more like the name of a small, gremlin-like creature. However, I assure you that they are very important in prop-making, and if you can master them both, you'll be able to make intricate, great-looking props in hardly any time!
Unless your work clothes require dry cleaning, you probably only go to the cleaner a few times a year. And for those few items in your closet for which you do, you have to then find the time and extra budget to make a trip all the way to the cleaners and back again. In the end, it can be quite the hassle.
While other devices are moving away from fingerprint scanners (cough, iPhone X), for many, a fingerprint scanner provides the best balance between security and speed. Typically, the rear fingerprint scanner on the LG V30 is quick and accurate, but every so often the phone will not recognize a registered fingerprint.
According to the National Safety Federation (NSF), pet bowls and toys carry coliform bacteria, including Staph bacteria, yeast, and mold. Additionally, an (unscientific) survey from Petco found that almost one-third of pet owners do not know the extent of contamination that their pet toys contain.
How to easily unclog your bathroom sink or kitchen sink and for zero dollars! Over time the bathroom sink or kitchen sink will get clogged up with gunk that will lead to poor drainage. Follow the steps outlined below for a hassle free unclogging solution.
Tons of freezers have built-in ice dispensers, but a lot of people never use them. But it turns out, all it takes to give it a new purpose is some duct tape, an X-Acto knife, and a piece of foam core.
Warm water is an essential part of life that we sometimes tend to take for granted. Over one billion people, or roughly one-seventh of the world's population, have no access to hot water.
Cheetos fingers is defined as the unpleasant (but mostly pleasant), oddly-colored residue left on the thumb, index finger, and middle finger after ravenously eating through a bag of—you guessed it—Cheetos. It can usually be cleaned up by licking your fingers (my favorite) or washing your hands (boooooo). For the folks who enjoy the latter, Cheetos fingers are an annoyance. As someone who enjoys this idiosyncrasy, I've never quite understood the disgust in getting your fingers all cheesed up.
Most of us have traded our desktop systems for laptops, tablets, and mobile devices, meaning there's a lot of outdated hardware sitting in attics. Want to give your old computer a new purpose? Matthew Chappee turned his iMac G4 into an HDTV using the guide by Dremel Junkie. One thing to note before you take on this project yourself is that if you want to use it to watch cable, you'll need a converter box to get around the MPAA's HDCP restriction. But, a converter box is considerably less expe...
For this project, I decided to rip apart a microwave I found in my neighbor's garbage can to see what was inside. With permission, of course! True story!
This is a refreshing spring update on your classic hamburger slider. Instead of using a ground beef patty, I am using shrimp tempura. This recipe calls for fresh truffles, but fresh truffles are hard to come by so feel free to use truffle oil (it is much more affordable and what I usually like to use). The flavor will be just as good.
Your Pixel has a few hidden features you probably don't know about, like the ability to clean up your funky contacts list. Since I'm sure you haven't manually organized your contacts since the inception of Android, there are likely some incomplete and duplicate contacts. Thankfully, your phone can fix this automatically.
Though you may scrub every inch of your kitchen, there are plenty of trouble areas that are nearly impossible to get clean: gunked-up tile grout, rust in the sink, and caked-on burners and grates on the stove. As far as burners and grates go, you're in luck, because there's a simple solution to returning even the grossest ones back to their original shine. The Key Is Ammonia
It's been a long time coming, but Google's Calendar app for Android has finally received a visual makeover. In the spirit of Android Lollipop, Google's new Material Design permeates throughout the update.
Thousands of history files, cookies, other unwanted files stored in your system as logs and other formats. To manually check each one is difficult. New computers are too fast by processor behavior, after some times of working it comes to slow performance.
If you weren't aware, all music purchased online through iTunes, Amazon, and other digital audio providers have information embedded that can be used to identify the buyer and transaction of the digital music file. This may seem like something you should be disclosed about in their terms of use, but it's not.
Being politically correct on social media sites is super boring. I've had my fair share of rage tweets and angry Facebook posts with some colorful wording, but sometimes using and F-bomb just gets the point across better. Now that Facebook is pushing out their new Graph Search, it might be time to clean up your profile. FaceWash is a web app that searches your Facebook profile for common bad words. You will need to give the app permission to access all of your wall posts (or course). Once acc...
You can feel it in your bones. You may die if you don't get this phone. There's just one problem — the price. Suddenly, you come across what seems like manna from heaven. That very device, at a deeply discounted rate, can be yours.
URL tracking codes: you'll see them on almost every link you copy online to share with friends and followers. It could be tens or hundreds of extra characters appended to the end of a URL, which websites and marketers use to tell how you got to the link in the first place. These excess tracking tokens not only make the links you share look sloppy and spammy — they could even invade your privacy.
The iPhone's "Accessibility" menu is one of those options that's very easy to overlook but incredibly handy in certain situations. You can set AssistiveTouch to help navigate your device, use a Bluetooth mouse when your screen is acting up, and enable the red screen filter for nighttime escapades. For as long as the menu has been available, it's been in the "General" settings, but not in iOS 13.
We've had a lot of fun digging into the Oreo update for the Galaxy S8. Thus far, we compiled a full list of the biggest changes and ran down some of our favorites. One of the most user-facing components on a smartphone is the camera. Samsung made sure to add some nice tweaks to the camera UI in Oreo too, bringing it more in-line with the camera on the Galaxy Note 8.
How would you feel if the stethoscope used by your doctor to listen to your heart and lungs was teeming with potentially unfriendly bacteria?
You seriously won't even recognize Twitter after this. Twitter has launched a major redesign, their first in years and it seems the app is finally starting to listen to what users are looking for — starting to being the keywords.
Multistate outbreaks of Salmonella infection in humans have led the Centers for Disease Control to advise caution when interacting with poultry. A press release on June 1st mentioned eight multistate outbreaks connected to backyard flocks. As of May 25, 372 people in 47 states were reported infected with the outbreaks' Salmonella strains. That means this year could be as bad as 2016, a record year, for salmonella outbreaks with 895 people infected.
Acanthamoeba keratitis (AK), a rare eye infection caused by the Acanthamoeba ameba found in tap water, affects a few dozen people in the US every year. In some cases, it can have devastating effects, like what Irenie Ekkeshis has experienced; She was blinded by AK in her right eye due to a contaminated contact lens.
As a commercial and potentially consumer product, one might assume it very unlikely to see the Microsoft HoloLens in the military marketplace. And that assumption would be completely wrong. One company from the Ukraine is currently working on using the mixed reality head-mounted computer for 360-degree vision inside armored tanks. If a tank crew could see the entire battlefield there are in, they would likely have a better chance of accomplishing their mission and avoiding damage. Tanks are l...
Consider the radish. This root vegetable is so sadly misunderstood sometimes, and that makes us sad because we adore its spicy flavor and crunchy texture. We're always on the lookout for unique food items that can be turned into a dish of wow and wonder with just a few simple steps, and radishes truly fit the bill.
I fry foods a lot. A LOT. We're talking wings by the dozen here. As a result, I go through a ton of frying oil. Now, frying oil isn't the most expensive ingredient out there, but it adds up when you fry regularly. Of course, I always reuse my oil, but straining it can be a huge mess and it gets to a certain point where enough is enough. It's time to start fresh.
If you're gluten-free, on a diet, or just cutting the carbs like me, eating a sandwich can be a dangerous game. There are traditional alternatives such as lettuce or egg wraps, but they have their drawbacks: they can't hold as many ingredients, they can be lack flavor when raw and un-rendered, and it's hard to layer the toppings and condiments to create your perfect bite.
As we go about our daily grind, our smartphones and tablets take a silent beating. Dirt, dust, oil, and grime that our hands have picked up immediately gets transferred over to our shiny pocket-sized computers every time we check the time or look for new notifications, and over the course of months, this can have a very noticeable adverse effect.
Due to their large size and added screen real estate, Apple included a new feature for the iPhone 6 and 6 Plus known as "Reachability." Essentially, this function makes reaching the top part of the display easier by double-tapping the home key to shift the screen down closer to your thumb.
You may have noticed your Note 10 came with quite a bit of bloatware. Even the unlocked version of the phone comes with Facebook preinstalled, and if you bought it from a carrier, it's much worse. Luckily, there's a way to remove any apps you don't want, and you don't need root or a paid app to do it.
OnePlus has now officially upgraded both the 5 and 5T to Android 8.1 Oreo. As implied by the version number, this isn't a huge update from Android 8.0 Oreo. However, OnePlus has included a few of their own features as well.
Wherever there are people, the party is sure to follow. Well, a party of microbes, at least. That is what scientists at NASA's Jet Propulsion Laboratory have found after a 30-day microbial observation of the inflatable lunar/Mars analog habitat (IMAH).
Foodborne infections often occur through the contamination of equipment, food-prep tools, and unsanitary surfaces. A recent report from the Centers for Disease Control and Prevention (CDC) reminds us that breast pump parts are part of the food-delivery chain — and they can become contaminated too.
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.
The Deepwater Horizon oil spill that began on April 20, 2010, was the largest maritime oil spill in history. Killing 11 people and discharging 4.1 million barrels of oil and natural gas into the Gulf of Mexico, the event was an unparalleled personal, environmental, and business disaster. It was also the first major oil spill to take place in the deep ocean.
