Characterizing a 12-hour biological clock.
SCIENCE sciencemag.org low-gravity environment that may also be under vacuum conditions. In outer space, neither vacuum nor sticky pads may hold. Jiang et al. devised a robotic gripper using gecko feet–inspired dry adhesives that can be activated or deactivated by shearing motions. Small adhesive patches can be mechanically coupled to allow for load sharing over a large area. By attaching these...
متن کاملA chiming biological clock?
What is it famous for? Without doubt, the Tanaguchi Foundation’s major achievement was the funding of a cyclotron at Osaka University between 1937 and 1943. The construction of that facility was a major boost to Osaka University and enabled it to attract many young scientists to its new Physics department. One of the Department’s first Professors was Hideki Yukawa, the theoretical physicist who...

متن کاملWhat makes a biological clock efficient ?
Biological clocks regulate the proper periodicity of several processes at the cellular and organismal level. The cell cycle and circadian rhythm are the best characterized among these but several other biological clocks function in cells at widely variable periodicity. The underlying molecular networks are controlled by delayed negative feedbacks, but the role of positive feedbacks and substrat...
