In biology, a biological life cycle (or just life cycle or lifecycle when the biological context is clear) is a series of changes in form that an organism undergoes, returning to the starting state.

Most biochemical reactions accelerate as temperature increases, but our daily circadian rhythms, which are underlain by gene regulatory and biochemical networks, remain constant, even as temperatures ...

Scientists have solved how circadian clocks within cyanobacteria, tiny organisms also known as blue-green algae, are able to precisely control when different genes are turned on and off during the ...

Researchers have advanced our understanding of the circadian clock, the biological cycle that synchronizes with light-dark exposure. They recently developed a method to study how the circadian clock ...

In April of this year, Spanish athlete Beatriz Flamini emerged into the light after a 500-day stay in a cave. Her descent underground is probably the longest undertaken by a long stretch. Flamini says ...

Biological oscillations, with frequencies ranging from milliseconds to years, play critical roles in the organization of cellular physiology in virtually every organism, although their origins and ...

New research has shown that the feedback mechanisms that were thought to keep the marine nitrogen cycle relatively stable over geological time can break down when oxygen levels in the ocean decline ...

Nearly all animals follow 24-hour activity cycles based on their genetically built-in circadian clocks. But one beetle species operates in 48-hour time chunks instead—apparently driven by a strict ...
