How cells measure themselves

Ever since scientists discovered cells under the microscope more than 350 years ago, they have noted that each type of cell has a characteristic size. From tiny bacteria to inches-long neurons, size matters for how cells ...

Lab study solves textbook problem: How cells know their size

Scientists have searched for years to understand how cells measure their size. Cell size is critical. It's what regulates cell division in a growing organism. When the microscopic structures double in size, they divide. One ...

Well-built muscles underlie athletic performance in birds

Muscle structure and body size predict the athletic performance of Olympic athletes, such as sprinters. The same, it appears, is true of wild seabirds that can commute hundreds of kilometers a day to find food, according ...

A light touch for membrane selectivity

Membranes that change their pore size in response to external stimuli, such as pH, heat and light, are set to transform separation science and technology. Such smart membranes developed by KAUST researchers display tunable ...
