New study measures cell weight by observation
It is not easy to guess the number of Jerry beans (a bean-shaped candy) in a candy jar, so try to guess the weight of a cell only by observation
Recently, a research team completed this "feat". They just used a standard laboratory microscope and a digital camera to successfully measure the weight of the cells. The researchers published the technical results online in the Physical Review Letter (PRL).
By analyzing how the target object bends and refracts light, the researchers can infer the composition of the target object using image processing algorithms.
Understanding the composition of an object can help scientists infer its density (on the right side of the figure above), and because the microscope can also be used to measure the size and volume of an object, the combination of these data allows researchers to measure the quality of the cell.
The research report pointed out that by using this technology, the participating scientists found that the average dry mass of human red blood cells was 27.2 trillionths of a gram.
This data is consistent with past measured values. In the past, obtaining this data depended on specially customized instruments.
The researchers pointed out that this new method is expected to help monitor how living cells grow and change over time, such as responding to disease or environmental changes.
Nightstands are small bedside tables that are typically placed next to a bed in a bedroom. They provide a convenient surface for placing items within arm's reach while you're in bed. Here are some key aspects to consider when choosing nightstands:
-
Size and Proportions: Measure the available space next to your bed to determine the appropriate size for your nightstands. Consider the height of your bed as well to ensure the nightstands are at a comfortable level for easy access.
-
Storage: Decide if you need nightstands with storage options. Some nightstands feature drawers, shelves, or cabinets that can be useful for storing items like books, reading glasses, medication, or other personal belongings.
-
Design and Style: Choose nightstands that complement the overall style and aesthetic of your bedroom. Whether your bedroom has a modern, contemporary, traditional, or rustic decor, select nightstands that blend well with the existing furniture and design elements.
-
Material: Nightstands come in a variety of materials, including wood, metal, glass, or a combination of these. Consider the durability, maintenance requirements, and visual appeal of different materials to find the one that suits your preferences.
-
Functionality: Think about the features you desire in a nightstand. This may include a built-in charging station or USB ports for convenient device charging, a pull-out tray for placing drinks or snacks, or integrated lighting for bedtime reading.
-
Surface Space: Consider the amount of surface space you need on the nightstand. Think about the items you typically keep by your bedside, such as a lamp, alarm clock, phone, or a glass of water, and ensure there is enough room to accommodate them comfortably.
-
Accessibility: Pay attention to the accessibility of the nightstand. Make sure it is within easy reach from your bed, allowing you to easily access items without straining or stretching too far.
-
Price and Brand: Set a budget for your nightstands and explore options within that range. Consider reputable furniture brands known for their quality and craftsmanship. Read customer reviews and research the brand's reputation to ensure you're getting a reliable product.
