In one sentence, describe what the following article is about: Put on gloves and tie back long hair to prevent contaminating the bacteria sample you'll be testing. Disinfect a workspace under the fume hood, or in another well-ventilated area. Check that the bunsen burner and microscope are functional before you begin. If the glass slide is dirty, wash it in soapy water to remove grease and dirt. Disinfect the slide with ethanol, glass cleaner, or whichever method is recommended by your laboratory. You can use the Gram stain method to help identify bacteria present in medical samples, or bacterial cultures grown in a petri dish. In order for the Gram stain to be useful, add a thin layer of the sample on the stain. A sample under 24 hours old is recommended, as older bacteria may have damaged cell walls that respond less predictably to gram staining. If using a tissue sample, add 12 drops onto the glass slide. Spread it evenly on the slide to form a thin smear, using the edge of a second sterilized glass slide. Allow it to air dry before continuing. If taking bacteria from a petri dish, sterilize an inoculation loop in a Bunsen burner flame until it glows, then let it cool. Use it to place a drop of sterile water on the slide, then sterilize and cool the loop again before transferring a tiny sample of bacteria and gently stirring into the water. Bacteria in broth should be mixed in a vortexer, then added with an inoculation loop as above, without adding the extra water. If you have a swab sample, roll the swab lightly across the slide. Heat will fix the bacteria to the slide, so they are not as easily rinsed off during the stain. Quickly pass the slide two to three times through a Bunsen burner flame, or heat it on top of an electric slide warmer. Do not overheat, or the samples may become distorted. If using a Bunsen burner, the flame should be a small, blue cone, not a tall orange one. Alternatively, the smear may be fixed by methanol instead, by adding 1-2 drops of methanol onto the dried smear, draining off the excess methanol, and allowing it to air dry. This method minimises damage to host cells, giving a cleaner background. A staining tray is a shallow metal, glass, or plastic dish with a small mesh or wire support running across the top. Place the slide on top of this support, so the liquids you'll be using can drain down into the tray. If you do not have a staining tray, the slide can be placed directly on top of a plastic ice cube tray.
Summary: Prepare for laboratory work. Sterilize a glass microscope slide. Add the sample to the slide. Heat fix the smear. Position the slide on a staining tray.

In one sentence, describe what the following article is about: Don't try to wing for someone who is significantly less appealing than you. These are harsh words, but they are true. You and your friend should be pretty similar in terms of your attractiveness, your outgoing nature, and your general appeal. Otherwise, the people you meet are likely to latch on to you, and your buddy will feel even worse. This doesn't mean that your friend can't appeal to people just because they're less attractive than you. But if they also lack charisma and flirting skills, while you're a smooth operator, then you won't have much luck. That's what the wingman is for, right? If you're winging, it's either because you owe your friend one, because you're not single, or just because you want your friend to have a good time. That means you can't switch roles and take over engaging the person that your friend has their eye on. Learn how to read cues to tell which person your friend wants. You might even want to designate hand, eye, or verbal signals beforehand. When you come up to a group, make it so they notice your friend first. Stand a bit behind and to the side of your leader literally positioning yourself like a wing. Also try to replicate the leader's attitude and body language if they're going for "super-friendly" or "super-chill," follow suit. You don't have to look like a total dud during this process, of course don't make it seem like you're hiding/lurking/cowering behind your buddy. Think of yourself as the Robin to their Batman. Let your friend make the introductions and start talking with the people, while you slowly make your way into the conversation. Otherwise, it won't be clear who's in charge. Remember that Batman always talks before Robin. If there is just one person, you can let your friend talk to them first and join in later. If there are two people, give your leader a few minutes to warm up to both of them before you join in. For the rest of the night, occupying the main target's friend(s) is your primary goal. If it's a group of two, spend your time focusing on the secondary person by distracting and keeping them busy. Try to pay as little attention as possible to the primary person, even if they seem interested in you. It's important that, once you figure out which person your friend wants, you stick to the other person from the beginning. If you try to switch off midway through, your targets will get confused.
Summary: Wing only for people who are roughly at your level. Give your leader first choice of people. Let your friend take the lead. Don't initiate the conversation yourself. Keep the target's friend busy while your leader works.

In one sentence, describe what the following article is about: You want to have as much information going into any transaction as you can. That way, you will be able to better evaluate any information that you counterpart in the transaction tells you. Therefore, check your credit score and get a copy of your credit report before you even start to visit with lenders. You can get a copy of your credit report at https://www.annualcreditreport.com/index.action. You can get your credit score directly from the credit bureaus, or from sites like creditkarma.com or credit.com. Try to make plans for your new car purchase several months in advance. That way, once you have read the information in your credit report and seen your credit score, you can take steps, such as making on-time payments and using less of your existing credit limits (try and keep it under 30%), to improve your credit score. If you're buying a car, your bad credit may not be a terrible hindrance to getting a good loan because the term of the loan is short and the car itself is essentially collateral (it can be repossessed if you fail to make payments). Therefore, it is imperative that you shop around. The average borrower with bad credit pays higher rates for an auto loan. If you're paying much more than that, there's an excellent chance that you can get a better deal elsewhere. Some dealers write up contingent or conditional contracts that allow them to increase the down payment or monthly payment of your loan. This type of term is extremely unfavorable to the borrower, and will almost certainly be used against a borrower as a pretext for repossessing the car. If a lender inserts this type of clause into the contract, run the other way. While a conventional lender, like a credit union or bank, might give a person with bad credit a higher interest rate than a person with good credit, they will often lend to borrowers with bad credit. Scrutinize dealers that cater to people with bad credit carefully. Those are often the lenders with the least favorable terms to the borrower. Extending the length of your loan may be tempting because it reduces the amount of your monthly payments, but you end up paying more in interest in the long run. This goes double if you are buying a used car. If the term of the loan is too long, you can end up making monthly payments on a car that long ago ceased to be drivable. Some lending contracts require the borrower to purchase extended warranties, aftermarket services and even insurance. If these have been added onto your contract, walk away.
Summary:
Check your credit. Plan in advance. Shop around. Read the fine print. Look at conventional lenders first. Focus on finding the lowest APR (annual percentage rate) over the shortest term. Watch out for non-essentials in your contract.
