Three-layered control of mRNA tails

Researchers have characterized how the essential mRNA poly(A) tails are synthesized in the budding yeast Saccharomyces cerevisiae. The study reveals several mechanisms controlling poly(A) tail lengths and hereby ensuring the robustness of gene expressi…

Faster path planning for rubble-roving robots

Robots that need to use their arms to make their way across treacherous terrain just got a speed upgrade with a new path planning approach. The improved algorithm path planning algorithm found successful paths three times as often as standard algorithm…

Origins of mutation

The precise transmission of genetic information from one generation to the next is fundamental to life. Most of the time, this process unfolds with remarkable accuracy, but when it goes awry, mutations can arise—some of them beneficial, some of them in…

Genetic program protects neurons from degeneration

Researchers have identified a previously unknown genetic program in the fruit fly. The genetic material involved controls the development of the neurons while also protecting them from degeneration. They have hardly changed in the course of evolution o…
