Deep proteome coverage advances knowledge of Treponema pallidum protein expression profiles during infection
Abstract Comprehensive proteome-wide analysis of the syphilis spirochete, Treponema pallidum ssp. pallidum, is technically challenging due to high sample complexity, difficulties with obtaining sufficient quantities of bacteria for analysis, and the inherent fragility of the T. pallidum cell envelope which further complicates proteomic identification of rare T. pallidum outer membrane proteins (OMPs). The main aim…

Academics can do more to disrupt and reframe the solution space for food system transformation
Food systems transformations are necessary, but will be difficult to achieve without disrupting current political framings and governance mechanisms. The academic community can do more to drive change at the science–policy interface to open a larger political, social and economic space for progress. Science–policy interfaces (SPIs) are social processes linking academics and decision-makers, allowing for…

An ON-type direction-selective ganglion cell in primate retina
Abstract To maintain a stable and clear image of the world, our eyes reflexively follow the direction in which a visual scene is moving. Such gaze-stabilization mechanisms reduce image blur as we move in the environment. In non-primate mammals, this behaviour is initiated by retinal output neurons called ON-type direction-selective ganglion cells (ON-DSGCs), which detect…

On-surface synthesis of a doubly anti-aromatic carbon allotrope
Abstract Synthetic carbon allotropes such as graphene1, carbon nanotubes2 and fullerenes3 have revolutionized materials science and led to new technologies. Many hypothetical carbon allotropes have been discussed4, but few have been studied experimentally. Recently, unconventional synthetic strategies such as dynamic covalent chemistry5 and on-surface synthesis6 have been used to create new forms of carbon, including…

Treating Climate and Nature Crisis as a Global Health Emergency
Over 200 health journals call on the United Nations, political leaders, and health professionals to recognize that climate change and biodiversity loss are one indivisible crisis and must be tackled together to preserve health and avoid catastrophe. This overall environmental crisis is now so severe as to be a global health emergency. The world is…

Pasteurella sp. associated with fatal septicaemia in six African elephants
Abstract The sudden mortality of African elephants (Loxodonta africana) in Botswana and Zimbabwe in 2020 provoked considerable public interest and speculation. Poaching and malicious poisoning were excluded early on in the investigation. Other potential causes included environmental intoxication, infectious diseases, and increased habitat stress due to ongoing drought. Here we show evidence of the mortalities…

Statement on General Assessment of the Role of Agriculture and Forestry in U.S. Carbon Markets
Natural climate solutions, such as improved forest management and agroforestry, are crucial for mitigating the worst impacts of climate change. Combined with cutting emissions and accelerating renewable energy, natural climate solutions offer immediate and cost-effective ways to tackle the climate crisis—while also supporting people and the planet. The voluntary carbon market is a necessary tool…
