The biological clock is present in almost all cells of an organism. As more and more evidence emerges that clocks in certain organs could be out of sync, there is a need to investigate and reset these clocks locally. Scientists ...

Plants lack eyes and ears, but they can still see, hear, smell and respond to environmental cues and dangers—especially to virulent pathogens. They do this with the aid of hundreds of membrane proteins that can sense microbes ...

Cellular origin is well explained by the "endosymbiotic theory," which famously states that higher organisms called "eukaryotes" have evolved from more primitive single-celled organisms called "prokaryotes." This theory also ...

In chemistry and biochemistry, a kinase is a type of enzyme that transfers phosphate groups from high-energy donor molecules, such as ATP, to specific substrates, a process referred to as phosphorylation. Kinases are part of the larger family of phosphotransferases. Kinases are not to be confused with phosphorylases, which carry out phosphorolysis, the breaking of a bond using an inorganic phosphate group; or with phosphatases, which remove phosphate groups.
