Channels that line the tail of sperm contain pores that allow the entry of calcium, which fuels their journey to the female reproductive tract.
At first glance, the slightly murky waters in the tube look like a scoop of stormwater, complete with leaves, debris, and even lighter threads in the mix. But in the Petri dish, the thin vermicelli-like threads floating delicately ...
Assembly of HIV-1, which causes AIDS, takes place on the inner plasma membrane leaflet of infected cells, a geometric building process that creates hexamers out of trimers of the viral Gag protein, as guided by Gag's N-terminal ...
Scientists at Kyoto University's Institute for Cell-Material Sciences have discovered a novel cluster compound that could prove useful as a catalyst. Compounds, called polyoxometalates, that contain a large metal-oxide cluster ...
Much remains to be discovered on how the HIV-1 virus infects our cells. Scientists know that it slips past the defenses of our immune system, entering white blood cells to deliver its genetic payload and hijack the cell's ...
Combining AlphaFold2 with experimental and computational techniques has helped scientists figure out the human nuclear pore complex's architecture in greater detail than ever before.
Whatever you are doing, whether it is driving a car, going for a jog, or even at your laziest, eating chips and watching TV on the couch, there is an entire suite of molecular machinery inside each of your cells hard at work. ...
Protein structures are typically determined by studying them in their purified form, outside the busy inner workings of the cell, and because of this, their biological relevance is often called into question. In a new study ...
Three years ago, the first ever image of a black hole stunned the world. A black pit of nothingness enclosed by a fiery ring of light. That iconic image of the black hole at the center of galaxy Messier 87 came into focus ...
The mystery of exactly how the SARS-CoV-2 virus infects human lung cells remains largely hidden to experimental scientists. Now, however, the devilish details of the mechanism by which the coronavirus fuses to host cells ...
