In an effort to reveal the inner workings of a protein that serves as a cell's damage detection system, scientists at Johns ...

The structure of enzymes determines how they control vital processes such as digestion or immune response. This is because the protein compounds are not rigid, but can change their shape through ...

Cells have an internal skeleton that maintains their structure and also drives their movement. Known as the cytoskeleton, ...

Inflammation is a good thing when it's fighting off infection, but too much can lead to autoimmune diseases or cancer. In efforts to dampen inflammation, scientists have long been interested in CC ...

Scientists have a new theory about the structure of DNA. Two strands of alternating sugar (deoxyribose) and phosphate groups make up the DNA double helix, and the strands were thought to be linked by ...

In cancer, a lot of biology goes awry: Genes mutate, molecular processes change dramatically, and cells proliferate uncontrollably to form entirely new tissues that we call tumors. Multiple things go ...

In 2015, researchers at UC San Francisco found a structure inside of tumor cells that biologists had never seen before. Even more surprising, a closer examination of the structure revealed that it ...

Retroviruses are viruses that have evolved the ability to write their genetic code into a cell's own DNA. The most ancient ...

For the first time, researchers have found one of the most important molecular machines in our cells uses a ‘twisting elevator’ mechanism, solving a mystery of how it transports crucial chemical ...

The current COVID-19 pandemic caused by a single-stranded RNA virus, thought to have jumped across species barriers to infect humans, has spread rapidly across the globe infecting over 10 million ...
