How adaptive capacity shapes the Adapt, React, Cope Response to climate impacts: insights from small-scale fisheries

Jennifer Selgrath & Kristen Green
As the impacts of climate change on human society accelerate, coastal communities are vulnerable to changing environmental conditions. The capacity of communities and households to respond to these changes (i.e., their adaptive capacity) will determine the impacts of climate and co-occurring stressors. To date, empirical evidence linking theoretical measures of adaptive capacity to community and household responses remains limited. Here we conduct a global meta-analysis examining how metrics of adaptive capacity translate to human responses...

Data from: Opportunities to catalyze improved healthcare access in pluralistic systems: a cross-sectional study in Haiti

Molly Klarman, Justin Schon, Youseline Cajusma, Stacey Maples, Valery M Beau De Rochars, Chantale Baril & Eric J Nelson
Introduction. Gains to ensure global healthcare access are at risk of stalling because some old resilient challenges require new solutions. Our objective was to identify determinants of intended versus actual care-seeking behaviors in a pluralistic healthcare system that is reliant on both conventional and non-conventional providers and discover opportunities to catalyze improved healthcare access. Methods. A cross-sectional study was conducted among households with children less than 5 years of age in Haiti. Households were randomly...

Canadian university syllabuses with academic and non-academic assigned readings identified.

John Willinsky & Catherine Baron
In the context of the significant court battles that are being fought over the potential copyright infringement involved in distributing the articles and excerpts assigned to students in university courses, this study analyzes 3,391 course syllabuses (2015-2020) from nine provinces and 34 universities across Canada. It identifies the types and proportions of required readings among academic and non-academic sources. Academic readings are assigned on 26.6 percent of the syllabuses, compared to 8.3 percent of syllabuses...

Data from: High-performance brain-to-text communication via handwriting

Francis Willett, Donald Avansino, Leigh Hochberg, Jaimie Henderson & Krishna Shenoy
Brain-computer interfaces (BCIs) can restore communication to people who have lost the ability to move or speak. In this study, we demonstrated an intracortical BCI that decodes attempted handwriting movements from neural activity in motor cortex and translates it to text in real-time, using a recurrent neural network decoding approach. With this BCI, our study participant, whose hand was paralyzed from spinal cord injury, achieved typing speeds that exceed those of any other BCI yet...

Data: Similar neural and perceptual masking effects of low-power optogenetic stimulation in primate V1

Spencer Chen, Giacomo Benvenuti, Yuzhi Chen, Satwant Kumar, Charu Ramakrishnan, Karl Deisseroth, Wilson Geisler & Eyal Seidemann
Can direct stimulation of primate V1 substitute for a visual stimulus and mimic its perceptual effect? To address this question, we developed an optical-genetic toolkit to “read” neural population responses using widefield calcium imaging, while simultaneously using optogenetics to “write” neural responses into V1 of behaving macaques. We focused on the phenomenon of visual masking, where detection of a dim target is significantly reduced by a co-localized medium-brightness pedestal. Using our toolkit, we tested whether...

Biological and chemical quantification of tadpole nurseries (phytotelmata)

Chloe Fouilloux, Shirley Jennifer Serrano-Rojas, Juan David Carvajal-Castro, Janne K. Valkonen, Philippe Gaucher, Marie-Therese Fischer, Andrius Pašukonis & Bibiana Rojas
Many species of Neotropical frogs have evolved to deposit their tadpoles in small water bodies inside plant structures called phytotelmata. These pools are small enough to exclude large predators but have limited nutrients and high desiccation risk. Here, we explore phytotelm use by three common Neotropical species: Osteocephalus oophagus, an arboreal frog that periodically feeds eggs to its tadpoles; Dendrobates tinctorius, a tadpole-transporting poison frog with cannibalistic tadpoles; and Allobates femoralis, a terrestrial tadpole-transporting poison...

Climate-driven limits to future carbon storage in California's wildland ecosystems

Shane Coffield, Kyle Hemes, Charles Koven, Michael Goulden & James Randerson
Enhanced ecosystem carbon storage is a key component of many climate mitigation pathways. The State of California has set an ambitious goal of carbon neutrality by 2045, relying in part on enhanced carbon sequestration in natural and working lands. We used statistical modeling, including random forests and climate analogues, to explore the climate-driven challenges and uncertainties associated with the goal of long-term carbon sequestration in forests and shrublands. We found that seasonal patterns of temperature...

Plasmodium infection is assocaited with cross-reactive antibodies to carbohydrate epitopes on the SARS-CoV-2 Spike protein

Moore, Khadidiatou Mangou, Fatoumata Diallo, Seynabou D. Sene … & Amy K. Bei
Individuals with acute malaria infection generated high levels of antibodies that cross-react with the SARS-CoV-2 Spike protein. Cross-reactive antibodies specifically recognized the sialic acid moiety on N-linked glycans of the Spike protein and do not neutralize in vitro SARS-CoV-2. Sero-surveillance is critical for monitoring and projecting disease burden and risk during the pandemic; however, routine use of Spike protein-based assays may overestimate SARS-CoV-2 exposure and population-level immunity in malaria-endemic countries.

Dataset: Charge order textures induced by non-linear couplings in a half-doped manganite

Ismail El Baggari, David Baek, Michael Zachman, Di Lu, Yasuyuki Hikita, Harold Hwang, Elizabeth Nowadnick & Lena Kourkoutis
Raw data associated with publication. The self-organization of strongly interacting electrons into superlattice structures underlies the properties of many quantum materials. How these electrons arrange within the superlattice dictates what symmetries are broken and what ground states are stabilized. Here we show that cryogenic scanning transmission electron microscopy (cryo-STEM) enables direct mapping of local symmetries and order at the intra-unit-cell level in the model charge-ordered system Nd1/2Sr1/2MnO3. In addition to imaging the prototypical site-centered charge...
