Most animal, plant and fungal cells contain organelles called mitochondria. These descendants of a primordial bacterial endosymbiont still preserve distinct genes and are known for their ability to create ATP as chemical energy. They also have other important functions, including cell signaling, viral and bacterial sensing, cell division, cell death, and innate and adaptive immune responses. Consequently, impairment in mitochondrial function can result in aging and age-related diseases.

In biology, the binding of cellular proteins to molecules called ligands produces a myriad of functions essential for life, including cell signaling and enzymatic action. In biotechnology and medicine, the ability of researchers to alter proteins to refine control over binding affinity and specificity can create tailored therapeutics with reduced side effects, highly sensitive diagnostic tools, efficient biocatalysis, targeted drug delivery systems and sustainable bioremediation solutions.

In 1937, President Franklin Roosevelt signed the National Cancer Act, launching a nationwide effort to combat the disease. Eighty-seven years later, despite significant progress, cancer treatment often falls short, with 50% to 80% of patients not responding to treatment and more than 600,000 cancer deaths annually in the United States. What if clinicians could predict the success of any cancer treatment, ensuring each patient receives the most effective care?

A long-standing goal of neuroscience is to understand how molecules and cellular structures on a microscale give rise to communication between brain regions at the macroscale. A study published in Nature Neuroscience now identifies, for the first time, hundreds of brain proteins that explain inter-individual differences in functional connectivity and structural covariation in the human brain.
