Control of gene activity through transcriptional regulatory elements is a major driving force in human evolution. A new study measures nascent transcription directly and shows that sequence, activity and three-dimensional organization of transcriptional regulatory elements all contribute to the evolution of gene activity within primate CD4(+) T cells.

Longevity of System Functions in Biology and Biomimetics: A Matter of Robustness and Resilience
Within the framework of a circular economy, we aim to efficiently use raw materials and reduce waste generation. In this context, the longevity of biomimetic material systems can significantly contribute by providing robustness and resilience of system ...

A Vexing Question in Motor Control: The Degrees of Freedom Problem
The human “marionette” is extremely complex and multi-articulated: anatomical redundancy (in terms of Degrees of Freedom: DoFs), kinematic redundancy (movements can have different trajectories, velocities, and accelerations and yet achieve the same goal,

Ecological communities are compared by the similarity or distinctness of their species. Taking into account community composition at a determined site, one could expect a similar reasoning to explain differences in both taxonomic and functional ...

On statistical power grid observability under communication constraints (invited paper)
Phasor Measurement Units (PMUs) have enabled real-time power grid monitoring and control applications realizing an integrated power grid and communication system. The communication network formed by PMUs has strict latency requirements.

Differential Effector Engagement by Oncogenic KRAS
Summary: KRAS can bind numerous effector proteins, which activate different downstream signaling events. The best known are RAF, phosphatidylinositide (PI)-3′ kinase, and RalGDS families, but many additional direct and indirect effectors have been ...

Mechanisms of Mutational Robustness in Transcriptional Regulation
Robustness is the invariance of a phenotype in the face of environmental or genetic change. The phenotypes produced by transcriptional regulatory circuits are gene expression patterns that are to some extent robust to mutations.
