Neurons connect with each other to form complex circuits that underlie mental activities. Mapping these connections to obtain a so-called wiring diagram is an essential step in learning how the brain works. At present, the only way to do this precisely enough is by using electron microscopy. However, this technique is so time-consuming that thousands of hours of work are typically required to image and analyze even the smallest tissue samples. To overcome this limitation, we developed a pipeline...

Targeted cellular delivery of therapeutic messenger RNAs and CRISPR/Cas9 offer transformative potential for personalized medicine, as well as basic scientific investigation. To enable the non-viral packaging and delivery of these molecular payloads to target cellular destinations we have invented a versatile synthetic approach based on designer DNA nanoparticles.

In humans, sounds that increase in intensity over time (up-ramp) are perceived as louder than down-ramping sounds. Here, we show that in mice this bias exists as well and is reflected in the complex nonlinearities of auditory cortex activity.

Light sheet fluorescence microscopy recently became a popular technique in developmental biology. This method allows for long-term imaging of many different samples with fast acquisition and most importantly, very low phototoxicity. However, so far most systems were custom-made and not available to the majority of biologists. This recently changed, when commercial systems entered the market. Here, we present a protocol explaining how to best make use of such systems and how to deal with the big...

Exploding seed pods are a dramatic example of the many and varied strategies that plants use to disperse their seeds. The energy to power these explosions was thought to be generated through the seed pods deforming as they dried out. But in the case of popping cress (Cardamine hirsuta) this turns out not to be so. These seed pods don't wait to dry before they explode.

Birds are capable of rapid and precise feats in flight. A new study reveals how flying hummingbirds use the vertical size and position of features in their environment to make course adjustments in the air.

Recent quantitative imaging studies revealed that intermittent bursts of de novo transcription is a general property of gene regulation. However, the underlying mechanism of transcriptional bursting has remained unanswered. We employed newly developed real time monitoring of transcription activities in living Drosophila embryos and showed that enhancers control the frequency of transcriptional bursting to regulate the level of gene expression during development. We also showed that a shared enhancer...

How do organs grow to reach the same size? Counterintuitively, randomness in cell growth is important to produce organs of uniform size and shape.

In mammalian cells, gene expression is usually under tight regulation where tiny regulatory RNAs, known as microRNAs, play a major role in controlling expression of proteins. When the cells are under stress they undergo a robust change in gene expression to combat stress by putting on several genes that are otherwise repressed by microRNAs. HFSP CDA awardee Suvendra Bhattacharyya and colleagues have now identified a new mechanism of stress induced regulation of these tiny regulatory RNAs in mammalian...
