A single-celled organism has an energy-producing enzyme with unique features.

From 500-million-year-old fat to a newly discovered virus, here are some stunners from The Scientist in 2018.

Low levels of a biochemical process involved in fat breakdown predicts weight gain and metabolic complications more than a decade later.

Insulin resistance and high levels of insulin and lipids all precede the development of metabolic dysfunction. Which metabolic factor is to blame?

Lipids and insulin play important roles in blood sugar regulation, and altered levels of either could kick start metabolic dysfunction.

A new experimental system demonstrates that precursors of ribonucleotides, amino acids, and lipids may have simultaneously arisen from the same prebiotic chemistry.

Male scientists stress mice out; using SCNT to reprogram adult cells; acetate can reach mouse brain, reduce appetite; WHO sounds “post-antibiotic era” alarm

Researchers report the first evidence of cryopreservation by an overwintering insect in which stores of an uncommon lipid are critical.

Shared sequences within the brain lipid-metabolism pathway between Neanderthals and modern Europeans highlight questions about how these genetic similarities arose.
