Insulin’s second century.

Insulin was first used to treat diabetes 100 years ago. The peptide is a lifesaving drug for people with type 1 diabetes, and it can improve the health of people with type 2 diabetes. In the century since it was first used as a therapy, researchers have learned much about how insulin works, developed processes for making large quantities of it, and engineered analogs that work faster or for longer periods. As insulin embarks on its second century, researchers continue to find ways to improve its performance. Read about innovations such as glucose-responsive insulin, which can keep blood sugar in check and reduce the risk of hypoglycemic episodes.

MATERIALS

Switchable smart window coating can heat or cool a room.

A phase-change material can convert near-infrared radiation from sunlight into heat or reflect it, all while staying transparent.

OPINION

International students deserve recognition and support.

Universities should better support international students, who have received little attention during the pandemic, writes graduate student Sakiru Abiodun in C&EN's first-ever Opinion column.

DRUG DISCOVERY

Hallucinogen chemistry guides antidepressant drug discovery.

X-ray crystal structures of psychoactive compounds bound to a key serotonin receptor suggest design strategies for non-hallucinogenic therapeutics.

2-D MATERIALS

Graphene growth process overcomes high-performance electronics logjam.

Researchers have grown wrinkle-free single sheets of single-crystal graphene directly on sapphire surfaces.
