When your tattoo is first healing, an antibiotic can help prevent infection and speed up the healing process. However, don't use it for more than one or two days because the cream can prevent oxygen from circulating around your healing skin, which is needed for the ink to seal. Apply the cream twice a day for up to two days. Do this when your tattoo is thoroughly dry. Using a small amount of cream, gently rub it over your tattoo with your fingers in a circular motion. Only apply a thin layer of cream so that your tattoo shines. Try to avoid applying cream over any scabs.  If you applied too much cream, use a clean paper towel to blot and remove the excess cream. Plain, unscented creams are generally used to treat tattoos. After you remove the bandage, do not apply another one. Your skin needs oxygen circulating around it to heal. Your tattoo will take two weeks to fully heal. Use the same procedure to wash and moisturize the tattoo. Each time you clean it, check to make sure that it is healing. Don't pick any scabs that form. Your doctor will most likely prescribe a steroid or an antibiotic to treat the infection. Signs of an infection are:  A very painful or hot to the touch tattoo after seven to ten days. A pimply or bumpy rash surrounding your tattoo. An extremely red, itchy and/or swollen tattoo after seven to ten days. Blistering or unusual scabbing. Pimples or boils that exude pus. Continued bleeding after three nights, or red streaking. A fever and/or swollen lymph nodes.

summary: Use an antibacterial ointment for up to two days. Apply a thin layer of unscented moisturizer. Leave your tattoo unbandaged. Clean twice daily for two weeks. Contact a doctor if you suspect you have an infection.

A new study done on empathy in dogs notes that dogs may yawn as a way to emotionally respond to someone that they are emotionally attached to, such as their owner. The researchers concluded that dogs will yawn in response to a real yawn from their owner to identify with their actions and express empathy. Test your dog’s ability to empathize with you by sitting in front of her and letting out a real yawn. Note if she yawns back at you, as this could be a sign of empathy. The next time you are upset, stressed out, or in a distressing situation, note how your household pet responds to you. Your dog may go over to you and lick you or nuzzle you as a sign of empathy or your cat may try to sit in your lap or rub against you to show that she is aware of your distress. These actions are indicators that your animal is able to identify and respond to your emotional state. Another key element of empathy is the ability to be self-aware, and researchers are currently testing the capacity for self-awareness in animals. You can do this on your own by placing your animal, such as a cat or dog, in front of a mirror and noting how they react to the mirror. If your cat or dog tries to paw or lick at their reflection, they may not be aware that they are looking at themselves in the mirror and may be believe they are seeing another cat or dog. You can test the animal’s capacity for self-awareness further by making a small mark in washable marker on the animal’s face. You can then note if the animal tries to rub off the mark on their face when they look in the mirror or if they ignore it completely. If they ignore it completely, this may be a sign that the animal is not self-aware and not able to respond to his own reflection.

summary: Watch if the animal yawns when you yawn. Note if the animal comforts you when you upset or in distress. Test the animal's empathy and self-awareness with a mirror.

This type of virus places all files on your USB into a hidden folder and replaces them with shortcuts of their original names. You can usually tell you have a shortcut virus if you see small arrows over the file or folder icons. If you double-click any of these shortcuts, the virus will activate and spread to your PC.. If you're using Windows 10, try using the Using Windows Security (Windows 10) method first. If you're using Windows 8.1 or earlier, try the Using Microsoft Safety Scanner (Windows 8.1 and Earlier) method  first. It's possible that Windows' own built-in antivirus software can fix the problem for you. If you're prompted to view the files on the drive or change your USB settings, just close the window for now. You'll need to know the drive letter of your USB drive (e.g., F: or D:) to remove the files. If you're not sure what it is, press the Windows key and the E key on the keyboard to open File Explorer, and then scroll down on the left panel to find your flash drive and corresponding drive letter. You may have to click an arrow or plus symbol next to "This PC" or "Computer" to see the drive.  A list of results will appear. A menu will expand. This opens an administrator-level command prompt. You may be prompted to verify your password to open up the window. Be sure to include the colon (:) after the letter. For example, if your USB drive is the F drive, type F: and press the Enter key. To do this, type del *.lnk and hit the Enter key. To do this, type attrib -s -r -h /s /d *.* and press the Enter key. If your drive was infected by a shortcut virus, this should restore your files to their original locations safely. To see a list of files on the drive, type dir /s and press the Enter key.
summary: Understand the shortcut virus. Plug the USB flash drive into your Windows PC. Press ⊞ Win+S to open the Search bar. Type command prompt. Right-click Command prompt in the search results. Click Run as administrator. Type your USB drive letter and press ↵ Enter. Run the command to delete all shortcuts. Run the command to restore your hidden files.
