A new biomaterial designed for repairing damaged human tissue doesn't wrinkle up when it is stretched. The invention from nanoengineers at the University of California, San Diego marks a significant breakthrough in tissue engineering because it more closely mimics the properties of native human tissue.

Read moreIn a new study, researchers quantified for the first time these error-suppressing processes for model nanoelectronic systems and estimated the minimum number of electrons necessary for reliable circuit logic. They found that physical fault-tolerance in transistor circuits suppresses the error rate per electron exponentially, while even the most efficient architectural fault-tolerance system only suppresses the error rate subexponentially.

Read moreScientists at Imperial College London have made the most accurate measurement yet of the shape of the humble electron, finding that it is almost a perfect sphere. The experiment, which spanned more than a decade, suggests that the electron differs from being perfectly round by less than 0.000000000000000000000000001 cm. This means that if the electron was magnified to the size of the solar system, it would still appear spherical to within the width of a human hair.

Read moreWith every bodily movement - from the blink of an eye to running a marathon - nerve cells transmit signals to muscle cells. To do that, nerve cells rely on tiny molecular motors to transport chemical messengers (neurotransmitters) that excite muscles cells into action. It's a complex process, which scientists are still trying to understand. A new study by Syracuse University researchers has uncovered an important piece of the puzzle.
