How are molecules transported across a cell membrane? How is a plant cell adapted to its function? How is the structure of red blood cells related to their role in transport? How are cells affected by the movement of water? How do cells transport small, lipid-soluble molecules across the ...
Why do cells need to use transport proteins to function? How do phospholipid molecules lead to compartmentalization of a cell? How are the proteins used for active transport different from those used for facilitated diffusion? How is the structure of red blood cells related to their role in tran...
What is the function of the spinal cord? Why must a cell go through the S phase before mitosis? Which type of cell to cell communication between two neighbouring cells is not reliant on physical contact between those cells? Do basophils become mast cells when they leave the circulation and ...
At 18, Katie Stubblefield lost her face. At 21, she became the youngest person in the U.S. to undergo the still experimental surgery. Follow her incredible story.
Localization in real-world conditions is challenging, as echoes provide erroneous information and noises mask parts of target sounds. To better understand real-world localization, we equipped a deep neural network with human ears and trained it to localize sounds in a virtual environment. The ...
Obviously, as boys generate bigger amount of "male" hormones, the condition of acne is more severe in them. It is not easy to treat acne in teenagers as their hormone level is constantly increasing. At the first stage of the treatment process, a very noticeable result of acne products can...
This is an important test that I recommend getting every time you check your thyroid function. TSH is a pituitary hormone that responds to low/high amounts of circulating thyroid hormone. If you’re new to thyroid lab testing, it may seem counterintuitive, but an elevated TSH means that you...
form, it doesn’t pose much harm to your dog. But sometimes yeast is allowed to grow out of control. This happens when there aren’t enough gut bacteria to compete with it. This can happen after antibiotic use, but there are other common causes (and we’ll talk about that in a bit...
You may think that there is little you can do to heal a cavity aside from go to your dentist and have it filled. While this is likely the most common option, it is not the only remedy. In fact, recent research suggests that a number of natural treatments can be used to reverse ...
High-speed stereomicroscopic measurements of cilia motion show that during the power stroke, the entire cilium—from the root to the distal point—remains virtually in a plane in a straight and taut posture4. The return stroke, on the other hand, is a continuously deforming, three-dimensional ...
