Sleep-promoting neurons switch between electrical activity and silence as a function of sleep need. The switch is operated by dopamine and involves the antagonistic regulation of two potassium channels.

In humans, gender specific differences in the prevalence of emotional disorders have been observed. A new study reveals the circuit and molecular mechanism that is responsible for gender biases in the occurrence of social and anxiety related disorders.

New research is shedding light on how leukaemia cells can survive cancer treatment, suggesting new possibilities for stopping them in their tracks. Intravital microscopy reveals that leukaemia cells are highly motile and do not associate with specific cellular structures of the bone marrow.

A salient feature of neuronal networks is the maintenance of balance between excitatory and inhibitory drives (E-I balance). Maintaining a balance of E and I inputs to neurons is crucial and severe imbalances can lead to excessive or insufficient activity that will degrade coding or produce neuropathologies such as epileptic seizures, autism spectrum and schizophrenic disorders. Over the past decade, several key theories have been developed that specify the conditions under which E-I balance may...

Ultrasound is among the most widely used biomedical imaging modalities, revealing babies' first pictures and helping diagnose disease. Yet ultrasound has limited ability to image specific molecular targets due to the lack of nanoscale contrast agents.

A novel arrangement of bacterial plasmids was observed using advanced fluorescence microscopy, shedding light on how bacteria maintain plasmids of multi-copies and the associated antibiotic resistant genes.

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.
