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 1–2 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: Babies with low muscle tone are usually described as floppy or feeling like a "rag doll" when held. This condition is known as hypotonia. Infants usually have flexed elbows and knees, whereas those with low muscle tone have loosely extended joints.  While infants with normal tone can be lifted and held from under the armpits, babies with hypotonia typically slip from their parents' hands because their arms rise without resistance.  Hypotonia results in weaker stomach muscles. Therefore, the stomach may extend outward more than usual.  Poor muscle control of the head (head rolling to the side or forward and backward) is also a symptom. Children affected by Down Syndrome often grow slower than other children, and are therefore shorter in stature. Newborns with Down Syndrome are usually small, and a person with Down Syndrome will most likely remain short through adulthood.  A study conducted in Sweden shows that the mean birth length is 48 centimeter (18.9 in) for both males and females with Down Syndrome. In comparison, the average length for those without the disability is 51.5 cm. Also look for excess fat or skin surrounding the neck. In addition, neck instability tends to be a common issue. While neck dislocation is uncommon, it is more likely to occur in people with Down Syndrome than those without the disability. Caretakers should be aware of a lump or pain behind the ear, a stiff neck that doesn't heal quickly, or changes in the way a person walks (appearing unsteady on their feet). This includes legs, arms, fingers, and toes. Those with Down Syndrome often have shorter arms and legs, a shorter torso, and higher knees than those without it.  People with Down Syndrome often have webbed toes, which is distinguished by the fusing together of the second and third toe.  There may also be a wide space between the big toe and second toe, and a deep crease on the sole of the foot where this space is. The fifth finger (pinky) can sometimes only have 1 flexion furrow, or place where the finger bends.  Hyperflexibility is also a symptom. This is identifiable by joints that seem to easily extend beyond the normal range of motion. A child with Down Syndrome may easily "do the splits," and may be at risk of falling over as a result. Having one singular crease across the palm of the hand, and a pinky finger that curves towards the thumb are additional characteristics.
Summary: Look for low muscle tone. Look for shortened height. Look for a short and wide neck. Look for short and stocky appendages.

In one sentence, describe what the following article is about: Having a purpose in life can help you find happiness, as well as stay positive and optimistic. If you’re working toward your purpose, your successes have more meaning and your hardships won’t seem as difficult.  Journaling can help you find your purpose. Write your responses to questions like these:  What do I want in life? What’s most important to me? Where do I see myself in 5 years? 10 years? What am I really good at?   Consider how you enjoyed spending your time when you were growing up. This may connect to your purpose. Think about your personal beliefs. How could they give you purpose? It’s normal to be dissatisfied with parts of your life. For example, you might not like your job, or you might be having a fight with a sibling. Confront one issue at a time to avoid becoming overwhelmed. Make a list of what you want to change, then prioritize it. Start with what’s most important for you. Much of what weighs on your mind comes from the past or the future. You can let go of these worries by living in the present. Focus on just this moment right now, allowing yourself to fully experience it.  Use your 5 senses to ground yourself in the moment. For example, smell the scents in the air, observe small details in the scene around you, and listen for the sounds you can pick out. Let go of distractions, such as your phone or earbuds. It’s normal to want to control every aspect of your life, but that’s an impossible goal. Trying to control everything actually makes you more stressed and less happy. Instead of trying to control every aspect of your life, focus on controlling the only thing you can -- your own reaction.  Let other people take care of themselves. Don’t be afraid to delegate tasks. Remind yourself that you can’t eliminate difficult moments from your life, but you can approach them differently. This may sound defeatist, but it’s actually the first step to improving your outlook. Don’t hold off on living because you’re waiting for the right circumstances. Your life is happening now! It’s okay to try to change your circumstances, as long as you focus on yourself and not others. You can change you, but not anyone else. You will encounter setbacks, as they happen to everyone. It’s easy to get tripped up by them, but don’t let them trap you in a mindset of defeat. Instead, view them as stepping stones on your path to success. Tell yourself, “I have to fail to learn the lessons I need to be successful.”
Summary:
Find your purpose. Focus on changing one thing at a time. Live in the moment using mindfulness. Let go of your need for control. Accept your circumstances for what they are. Remind yourself that setbacks are temporary.
