Rats spontaneously move their whiskers upon surfaces (whisking) to finely examine them. Our work demonstrates for the first time that these animals are also able to discriminate bilaterally and simultaneously two surfaces, while running and without whisking.

Microtubules, the largest filaments of the internal skeleton of a cell, are typically emanating from a central structure inside a cell, the centrosome. However, the cells of the early mammalian embryo are lacking centrosomes. Therefore, it has remained unknown how the microtubule cytoskeleton is organized during the first stages of development. Here, we discovered how mammalian cells organize their internal skeleton during the earliest stages of embryonic life.

It has been a longstanding puzzle how aquatic animals can effectively navigate within water currents, even in complete darkness where obvious visual cues from the stationary shore or river bottom are missing. In a recent study, published in Nature, it was demonstrated that larval zebrafish use the hair cells of their lateral line to detect tiny gradients in the local water velocity and that they can utilize this information in an elegant way to decipher the speed and direction with which they are...

The physical growth of synthetic cell-sized compartments genetically programmed but deprived of complex enzymatic membrane synthesis mechanisms remains an open question relevant to the origin of life and to the chemical synthesis of artificial cells. In this work, a HFSP-funded research collaboration demonstrates that phospholipids vesicles capable of expressing proteins can physically grow in a bath of primitive building blocks that spontaneously insert into the vesicles' membrane.

Our research shows that it takes a fraction of an eye blink for bats to raise the volume of their voice in response to noise. Echolocating bats produce high frequency sounds and listen to echoes to find objects in their environment. Here, we measured and modeled the time it takes for listening bats to adjust the volume of their calls when they track prey in the presence of noise. Bats achieve this extremely rapid vocal response by continuously integrating the sound pressure level of background noise...

A new microscopy method, dubbed Elastic Resonator Interference Stress Microscopy (ERISM), images the extremely weak mechanical forces that living cells apply when they move, divide, and probe their environment. Forces exerted by cells are fundamental for many physiological processes including locomotion - such as during immune response or tumor metastasis - cell growth, wound healing, and tissue formation and repair. However, existing methods for monitoring cellular forces are often indirect and...

Meiosis is a specialized cell division process that separates each pair of homologous chromosomes to generate haploid reproductive cells such as sperm, eggs, and pollen. Using state-of-the-art super-resolution microscopy methods, we determined the three-dimensional architecture of the central core of meiotic chromosomes, known as 'axes', to better understand their functions in meiosis.

Organellar trafficking is catalyzed by complex formation of SNARE proteins. In this study, a new technique based on fluorescence lifetime imaging microscopy is developed to visualize the subcellular location of SNARE complex formation.

In cancer, immune cells infiltrate tumors but whether they can exit the tumor or where they go next was unknown until now. We have shown that activated T cells are the main immune cells to leave tumors and can move to other tumors and draining lymph nodes suggesting a potential role in patrolling for tumor metastases.

Human and animal behavior is thought to arise from many brain regions interacting with one another, forming a network. Combined computational and experimental approaches revealed that such functional brain networks can be used to predict brain region importance for particular behaviors.
