Researchers have found that opsin 3 -- a protein closely related to rhodopsin, the protein that enables low-light vision -- has a role in adjusting the amount of pigment produced in human skin, a determinant of skin color.

Researchers at the University of Arizona have completed the first-of-its-kind study that could aid in the treatment, diagnosis and prevention of cervical cancer by identifying cervicovaginal metabolic signatures, or "fingerprints" that distinguish patients with HPV, pre-cancerous cervical conditions and cancer.

A new study is providing insight into how the pursuit of starch may have driven evolutionary adaptations in these and other hungry mammals.

Regardless of how much you exercise or how balanced your diet is, controlling your weight is more brain-related than you might have thought. In a recent study, researchers show for the first time in mice that the acyl-CoA-binding protein, or ACBP, has a direct influence on the neurons that allow rodents and humans to maintain a healthy weight.

Small differences in a liver cell protein have significant impacts on hepatitis C virus replication in mice and humans, findings that could facilitate the development of a mouse model of the infection.

A toxic protein linked to Huntington's disease can move from neuron to neuron through a nanotube tunnel whose construction is initiated by a protein called Rhes, say scientists.

Dr Mikhail Savitski, the Team Leader and Head of the Proteomics Core Facility at the European Molecular Biology Laboratory, has made several impressive contributions to the proteomics field, including the development of thermal proteome profiling (TPP).

Dr Evangelia Petsalaki is a Group Leader at the European Bioinformatics Group, where her research team study human cell signaling in health and disease conditions. Collaborating with teams specializing in MS, imaging and cell biology, their aim is to make both predictive and conditional models so they can anticipate what might happen in a biological network under different conditions.

We spoke to Cristina Paulino, Assistant Professor in high-resolution cryo-electron microscopy (cryo-EM) at the University of Groningen, to learn about the role cryo-EM plays in her group's work in the study of membrane protein structure and function.
