Hyaluronic acid-binding, anionic, nanoparticles inhibit ECM degradation and restore compressive strength in aggrecan-depleted articular cartilage explants

Marcus Deloney, Alyssa Panitch, Blaine Christiansen, Parssa Garoosi & Vanessa Dartoura
Joint trauma results in the production of inflammatory cytokines that stimulate the secretion of catabolic enzymes which degrade articular cartilage. Molecular fragments of the degraded articular cartilage further stimulate inflammatory cytokine production with this process eventually resulting in post-traumatic osteoarthritis (PTOA). The loss of aggrecan is considered an early step in the progression of PTOA. Aggrecan, composed of a core protein linked to sulfated glycosaminoglycans (GAGs), associates with hyaluronic acid (HA) via a link protein....

Data From: Polygenic basis and the role of genome duplication in adaptation to similar selective environments

Matthew Campbell, Eric Anderson, John Carlos Garza & Devon Pearse
Genetic changes underlying adaptation vary greatly in terms of complexity and, within the same species, genetic responses to similar selective pressures may or may not be the same. We examine both complex (supergene) and simple (SNP) genetic variants occurring in populations of rainbow trout (Oncorhynchus mykiss) independently isolated from ocean access and compared them to each other and to an anadromous below-barrier population representing their ancestral source to search for signatures of both parallel and...

Cargo routing and disadvantaged communities

Anmol Pahwa & Miguel Jaller
Freight is fundamental to economic growth, however, the trucks that haul this freight are pollution intensive, emitting criteria pollutants and greenhouse gases at high rates. The increasing volume and time-sensitivity of freight demand over the past decade has encouraged carriers to take the fastest route, which is often not an eco-friendly route. The increase in urban freight movement has thus brought along negative externalities such as congestion, emissions, and noise into cities. Alternative fuel technologies,...

Bacteria isolated from bengal cat (Felis catus × Prionailurus bengalensis) anal sac secretions produce volatile compounds associated with animal signaling

Mei Yamaguchi, Guillaume Jospin, Holly Ganz, David Coil, Jonathan Eisen, Adrienne Cho, Thant Zaw, Mitchell McCartney & Cristina Davis
Anal sacs are an important odor producing organ found across the mammalian Order Carnivora. Secretions from the anal sac may be used as chemical signals by animals for behaviors ranging from defense to species recognition to signaling reproductive status. In addition, a recent study suggests that domestic cats utilize short-chain free fatty acids in anal sac secretions for individual recognition. The fermentation hypothesis is the idea that symbiotic microorganisms living in association with animals contribute...

A microbial survey of the International Space Station (ISS)

Jonathan Eisen, David Coil & Jenna Lang
Background Modern advances in sequencing technology have enabled the census of microbial members of many natural ecosystems. Recently, attention is increasingly being paid to the microbial residents of human-made, built ecosystems, both private (homes) and public (subways, office buildings, and hospitals). Here, we report results of the characterization of the microbial ecology of a singular built environment, the International Space Station (ISS). This ISS sampling involved the collection and microbial analysis (via 16S rDNA PCR)...

Signatures of Environmental Adaptation During Range Expansion of Wild Common Bean (Phaseolus vulgaris)

Paul Gepts
Landscape genomics integrates population genetics with landscape ecology, allowing the identification of putative molecular determinants involved in environmental adaptation across the natural geographic and ecological range of populations. Wild Phaseolus vulgaris, the progenitor of common bean (P. vulgaris), has a remarkably extended distribution over 10,000 km from northern Mexico to northwestern Argentina. Earlier research has shown that this distribution represents a range expansion from Mesoamerica to the southern Andes through several discrete migration events and...

Vibrational Neutron Scattering Spectra for Undoped and Doped P3HT

Thomas Harrelson, Jun Li & Adam Moule
Doped semiconducting polymers have garnered vast research interest in photovoltaic, transistor, thermoelectric, and sensor applications. P3HT is a canonical semiconducting polymer that self-assembles into a mixture of crystalline and amorphous domains. Doping P3HT can increase the observed conductivity by several orders of magnitude. The vibrations of the polymer are sensitive to the local morphology of the film, and the morphology of the film changes upon doping. Vibrational neutron spectroscopy is a method for identifying vibrational...

Regional and disease-related differences in properties of the equine temporomandibular joint disc

Derek Cissell
Temporomandibular joint (TMJ) disorders are increasingly recognized in animals. The articular disc plays a major role in TMJ disorders in people, but its role in the pathogenesis of TMJ disease in animals is not well understood. This study characterizes properties of the equine TMJ disc, including regional variation within discs as well as differences in properties associated with naturally-occurring TMJ osteoarthritis.

Defining hydrogel properties to instruct lineage- and cell-specific mesenchymal differentiation

Kent Leach
The maintenance and direction of stem cell lineage after implantation remains challenging for clinical translation. Aggregation and encapsulation into instructive biomaterials after preconditioning can bolster retention of differentiated phenotypes. Since these procedures do not depend on cell type or lineage, we hypothesized we could use a common, tunable platform to engineer formulations that retain and enhance multiple lineages from different cell populations. To test this, we varied alginate stiffness and adhesive ligand content, then encapsulated...

Channel types predictions for the Sacramento River basin

Hervé Guillon, Colin F. Byrne, Belize Arela Albin Lane, Samuel Sandoval Solis & Gregory Brian Pasternack
Hydrologic and geomorphic classifications have gained traction in response to the increasing need for basin-wide water resources management. Regardless of the selected classification scheme, an open scientific challenge is how to extend information from limited field sites to classify tens of thousands to millions of channel reaches across a basin. To address this spatial scaling challenge, we leveraged machine learning to predict reach-scale geomorphic channel types using publicly available geospatial data.

Effect of stressors on the carrying capacity of spatially distributed metapopulations

Bo Zhang, Donald DeAngelis, Wei-Ming Ni, Yuanshi Wang, Lu Zhai, Alex Kula, Shuang Xu & David Van Dyken
Stressors such as antibiotics, herbicides and pollutants are becoming increasingly common in the environment. The effects of stressors on populations are typically studied in homogeneous, non-spatial settings. However, most populations in nature are spatially distributed over environmentally heterogeneous landscapes with spatially-restricted dispersal. Little is known about the effects of stressors in these more realistic settings. Here, we combine laboratory experiments with novel mathematical theory to rigorously investigate how a stressor’s physiological effect and spatial distribution...

Kelsey Horvath, Rachel Toaff-Rosenstein, Cassandra Tucker & Emily Miller-Cushon
With growing interest in provision of brushes to cattle, and implications of brush use for behavioral development and welfare, there is a need to validate methodology for quantifying grooming behavior. Our objectives were to characterize patterns of brush use, including bouts, diurnal activity, and individual variability over 24-h periods and to validate time sampling methodologies to characterize these traits, including instantaneous recording at various time intervals and continuous recording for subsets of the day. Data...

Integrated Crop-Livestock Systems achieve comparable crop yields to specialized systems: a meta-analysis

Caitlin Peterson, Leonardo Deiss & Amelie Gaudin
Production systems that feature temporal and spatial integration of crop and livestock enterprises, also known as integrated crop-livestock systems (ICLS), have the potential to intensify production on cultivated lands and foster resilience to the effects of climate change without proportional increases in environmental impacts. Yet, crop production outcomes following livestock grazing across environments and management scenarios remain uncertain and a potential barrier to adoption, as producers worry about the effects of livestock activity on the...

Understanding Behavioral Responses of Wildlife to Traffic to Improve Mitigation Planning

Fraser Shilling
Creating and maintaining sustainable transportation systems depends in part on understanding and mitigating ecological impacts. Wildlife crossing structures (WCS) are often used to mitigate impacts on wildlife populations. WCS and existing structures may provide passage for multiple species, depending on their sensitivity to traffic disturbance and perception of the roadway. In a previous project, we found that traffic conditions and traffic noise could reduce WCS effectiveness in facilitating passage of diverse and sensitive species. In...

Exploring the role of attitude in the acceptance of self-driving shuttles

YAN XING, Susan Handy, Giovanni Circella, Yunshi Wang & Farzad Alemi
Self-driving vehicles, as a revolution in mobility, are emerging and developing rapidly. However, public attitudes toward this new unproven technology are still uncertain. Given the significant influence of attitude toward a new technology on the intention to use it, the question arises as to why some people are in favor of this technology whereas others are not. Additionally, questions about the key attitudes influencing self-driving technology acceptance, where these attitudes come from, and how they...

Genome Synteny Has Been Conserved Among the Octoploid Progenitors of Cultivated Strawberry Over Millions of Years of Evolution

Michael Hardigan, Mitchell Feldmann, Anne Lorant, Kevin Bird, Steven Knapp, Patrick Edger, Glenn Cole, Charlotte Acharya & Randi Famula
Allo-octoploid cultivated strawberry (Fragaria × ananassa) originated through a combination of polyploid and homoploid hybridization, domestication of an interspecific hybrid lineage, and continued admixture of wild species over the last 300 years. While genes appear to flow freely between the octoploid progenitors, the genome structures and diversity of the octoploid species remain poorly understood. The complexity and absence of an octoploid genome frustrated early efforts to study chromosome evolution, resolve subgenomic structure, and develop a...

Structure and distribution of chalky deposits in the Pacific oyster using x-ray computed tomography (CT)

Roxanne Banker & Dawn Sumner
Oysters are unusual among bivalves in that they possess chambers, often filled with soft, chalky calcite, that are irregularly scattered throughout the shell. Because the function of these so-called chalky deposits is still unclear, evaluating the growth and distribution of chalk is important for elucidating the ecological function of this unique shell trait. Specimens of the Pacific oyster Magallana gigas, an oyster well known for chalk expression, were grown in Bodega Harbor, Bodega Bay, CA....
