Many remarkable phenotypes have repeatedly occurred across vast evolutionary distances. When convergent traits emerge on the tree of life, they are sometimes driven by the same underlying gene families, while other times, many different gene families are involved. Conversely, a gene family may be repeatedly recruited for a single trait or many different traits. To understand the general rules governing

What is the neural substrate that enables the cerebral cortex to control a single mystacial vibrissa and orchestrate its movement? To answer this question, we injected rabies virus into the intrinsic muscle that protracts the rat C3 vibrissa and used retrograde transneuronal transport to identify the cortical neurons that influence the muscle. A surprisingly diverse set of cortical areas is the origin

Historically, endocrine cells were perceived to coordinate their output in a uniform manner. Recently however, single-cell technologies have uncovered heterogeneity within these populations, indicating that individual cells may operate as independently regulated units. Using high-resolution tools such as single-molecule fluorescent in situ hybridization (sm-FISH) and single-cell RNA sequencing (scRNA-seq)

Biomass burning can affect climate via the emission of aerosols and their subsequent impact on radiation, cloud microphysics, and surface and atmospheric albedo. Biomass burning emissions (BBEs) over the boreal region have strongly increased during the last decade and are expected to continue increasing as the climate warms. Climate models simulate aerosol processes, yet historical and future Coupled

Hundreds of human mutations are linked to autism and related disorders, yet the functions of many of these mutated genes during vertebrate neurodevelopment are unclear. We generated 27 zebrafish mutants with presumptive protein-truncating mutations or specific missense variants corresponding to autism-risk alleles in 17 human genes. We observed baseline and stimulus-driven behavioral changes at larval

The globus pallidus externa (GPe) is a heterogeneous nucleus of the basal ganglia, with intricate connections to other basal ganglia nuclei, as well as direct connections to the cortex.

Familial advanced sleep phase (FASP) is a heritable human sleep trait characterized by early sleep onset and offset times. We have identified five variants in five different families in the human voltage-gated calcium channel subunit alpha1 D ( CACNA1D ) that cosegregate with FASP. The variants in CACNA1D lead to altered channel dynamics in vitro. A mouse model of the E427K variant has a normal circadian

We employed cryogenic X-ray Raman spectroscopy to investigate the early-stage decomposition of the high explosive molecule hexanitrohexaazaisowurtzitane (CL-20).

Genomic diversity in pathogen populations is foundational for evolution and adaptation. Understanding population-level diversity is also essential for tracking sources and revealing detailed pathways of transmission and spread. For bacteria, culturing, isolating, and sequencing the large number of individual colonies required to adequately sample diversity can be prohibitively time-consuming and expensive

One key component of study design in population genetics is the “geographic breadth” of a sample (i.e., how broad a region across which individuals are sampled). How the geographic breadth of a sample impacts observations of rare, deleterious variants is unclear, even though such variants are of particular interest for biomedical and evolutionary applications. Here, in order to gain insight into the

Regnase-1 is a ribonuclease that regulates inflammation in immune cells by degrading cytokine mRNA. Regnase-1 was identified as one of the frequently mutated genes in the inflamed colorectal epithelium of patients with ulcerative colitis; however, its significance in intestinal epithelial cells during the tumorigenic process remains unknown. Therefore, we developed an Apc Min/+ mouse model lacking

Active conservation management to reduce extinction risk includes increasing habitat connectivity, translocations from captive populations, or intensive surveillance of highly protected closed populations. Advances in sequencing technology mean that it is now possible to consider the genomic impacts

The rapidly expanding lithium-ion battery (LIB) market has heightened the demand for efficient diagnostics for in-use cells and the reliable grading of used cells.

In this study, we further examine the sensitivity of this previous work to varying prescribed

Industrial activities have increased the supply of iron to the ocean, but the magnitude of anthropogenic input and its ecological consequences are not well-constrained by observations.

Climate model projections of how DMS emissions change with global warming are largely uncertain, even

Biomolecular condensates form by phase separation of biological polymers and have important functions in the cell—functions that are inherently linked to their physical properties at different scales.
