At physiological temperatures, cell membranes are fluid; at cooler temperatures, they become gel-like. Scientists who model membrane structure and dynamics describe the membrane as a fluid mosaic ...

Cell structure Description Function Cell type Cell wall Freely permeable layer surrounding cell membrane. The cell wall of plant cells is made from cellulose. This gives them a rigid structure.

The membrane that surrounds cells in living organisms is extremely flexible and sensitive. How it protects itself from damage ...

This is particularly relevant when considering (i) patches of selected lipid and protein composition fusing with, or pinching off from, a biological membrane during the normal life of the cell 5 ...

Researchers at Forschungszentrum Julich have now used cryo-electron microscopy to uncover intriguing new information. Known from the photosynthetic system of plants, algae, and bacteria, the membrane ...

Bacteria that cause diseases, so-called pathogens, develop various strategies to exploit human cells as hosts to their own ...

Plant cells have a rigid cell structure. They are made up of a cell wall, cell membrane, cytoplasm, vacuole, nucleus, and chloroplasts. Plants feel firm because of their cellular walls.

It plays a crucial role in organizing the membrane and influencing the behavior of receptors embedded within it. But ...

Researchers used Raman spectroscopy to study cholesterol in cell membranes, discovering unique structural variations. This ...

The formation of pores by a particular protein, gasdermin D, plays a key role in inflammatory reactions. During its ...

In a move akin to puncturing an egg yolk without breaking the shell or egg white, researchers have figured out how to pierce ...

▲摘要：陆地光合作用每年清除的二氧化碳量是化石燃料排放的6倍。然而，通过分解后大部分的碳回到大气中。我们在地下2米处发现了一根3775年前的古原木，它的保存时间远远超过预期。这根木材保存得近乎完美，与现代样品相比，碳损失不到5%。它没有腐烂的原因可能是埋藏地点致密粘土的低渗透性。
