How to Enable a Mouse for a Laptop

Although today's small, lightweight laptops allow for ergonomic typing and browsing, many users still prefer a handheld optical mouse for navigation. When you need to make precise movements with your cursor, such as while using image-editing software or drawing a diagram in Paint, the optical mouse is the preferred choice over the built-in touchpad. Whether you are using a wireless optical mouse or a USB mouse, enabling it as your primary navigational tool is easy to do. Verify that the mouse you are thinking of purchasing is compatible with your laptop model. Browse the mouse manufacturer's website or read the packaging to ensure that it will function with your computer. Plug the mouse's USB cable into the matching port on the side of your laptop. Restart your computer while the mouse is connected. Once the system has rebooted, the New Hardware Wizard will run and install the driver required for proper functioning of the mouse. Move your mouse a few times to confirm that the cursor responds. You may now use your optical mouse as well as your computer's touchpad for navigation. Install the required batteries in the wireless mouse. On most models, you can lift the top panel on the mouse to expose the battery compartment. AA batteries are typically used to power wireless mice. Plug the USB receiver bundled with the mouse into the port on the side of your computer. Press and hold the small button on the underside of the mouse and the button on the USB receiver simultaneously. Continue holding the buttons down until the tracking light on the underside of the mouse illuminates. Turn the mouse over and begin moving it to ensure that the cursor tracks properly.

Brush-furred mouse

The brush-furred mice, genus Lophuromys are a group of rodents found in sub-Saharan Africa. They are members of the subfamily Deomyinae, a group only identifiable through molecular analysis. Lophuromys is also known as the brush-furred rats, harsh-furred rats or coarse-haired mice.

In mouse oocytes

In many animal cells, centrioles and spindles keep nuclei centered within a cell for mitotic, meiotic, and other processes. Without such a centering mechanism, disease and death can result. While mouse oocytes do have centrioles, they play no role in nucleus positioning, yet, the nucleus of the oocyte maintains a central position. This is a result of cytoplasmic streaming. Microfilaments, independent of microtubules and myosin 2, form a mesh network throughout the cell. Nuclei, positioned in non-centered cell locations, have been demonstrated to migrate distances greater than 25 microns to the cell center. They will do this without going off course by more than 6 microns when the network is present. This network of microfilaments has organelles bound to it by the myosin Vb molecule. Cytoplasmic fluid is entrained by the motion of these organelles, however, no pattern of directionality is associated with the movement of the cytoplasm. In fact, the motion has been demonstrated to fulfill Brownian motion characteristics. For this reason, there is some debate as to whether this should be called cytoplasmic streaming. Nonetheless, directional movement of organelles does result from this situation. Since the cytoplasm fills the cell, it is geometrically arranged into the shape of a sphere. As the radius of a sphere increases, surface area increases. Further, the motion in any given direction is proportional to the surface area. So thinking of the cell as a series of concentric spheres, it is clear that spheres with larger radii produce a greater amount of movement than spheres with smaller radii. Thus, the movement toward the center is greater than the movement away from the center, and net movement pushing the nucleus towards a central cellular location exists. In other words, the random motion of the cytoplasmic particles create a net force toward the center of the cell. Additionally, the increased motion with the cytoplasm reduces cytoplasmic viscosity allowing the nucleus to move more easily within the cell. These two factors of the cytoplasmic streaming center the nucleus in the oocyte cell.

What is the BEST way to catch an elusive crafty mouse?

How to catch a crafty mouse? With gift certificates to a fabric store, of course. No, wait, that's what works for me. Here is a way that is both humane and involves that great passion of mice: peanut butter. The down side is that it requires a fair bit of patience and sitting still. Empty and clean out a tall-ish kitchen trash can, lay it on its side with a piece of paper smeared with peanut butter. You sit next to it, keeping very still and quiet. When the mouse comes to check out the peanut butter, you quickly tip the trash can back to an upright position. This traps the mouse at the bottom, and you can take it outside for a release into the wild
