Committed emissions from existing energy infrastructure jeopardize 1.5 °C climate target
Nature, 2019 Net anthropogenic emissions of carbon dioxide (CO2) must approach zero by mid-century (2050) in order to stabilize the global mean temperature at the level targeted by international efforts1–5.

Functional parameters of spermatozoa obtained by a new selection device
FEBS Open Bio, EarlyView.This study compares density gradient centrifugation and the LensHooke CA0™ device for sperm separation. DGC requires multiple steps, specialized equipment, and technical expertise. In contrast, the CA0 device offers key practical and methodological advantages, resulting in a faster, simpler, and more affordable sperm selection method.

Moving from Walkability? Evaluation Traditional and Merging Data Sources for Evaluating Changes in Campus-Generated Greenhouse Gas Emissions [PDF]
, 2019 Universities are increasingly committing to reduce campus-generated greenhouse gas emissions, whether voluntarily or in response to a legal mandate. As an initial step to keeping these commitments, universities need an accounting of baseline greenhouse ...

Global CO2 emissions from cement production, 1928–2018
Earth System Science Data, 2019 . Global production of cement has grown very rapidly in recent years, and, after fossil fuels and land-use change, it is the third-largest source of anthropogenic emissions of carbon dioxide. The availability of the required data for estimating emissions

Offsetting methane emissions — An alternative to emission equivalence metrics
International Journal of Greenhouse Gas Control, 2013 It is widely recognised that defining trade-offs between greenhouse gas emissions using 'emission equivalence' based on global warming potentials (GWPs) referenced to carbon dioxide produces anomalous results when applied to methane. The short atmospheric lifetime of methane, compared to the timescales of CO2 uptake, leads to the greenhouse warming ...

CD9‐association with PIP2 areas is regulated by a CD9 salt bridge
FEBS Open Bio, EarlyView.The tetraspanin CD9 has an intracellular salt bridge. If CD9 opens, open‐CD9 moves from PIP2‐rich areas to regions populated by its interaction partner EWI‐2. Hence, the state of the salt bridge regulates the distribution of CD9 and by this CD9‐EWI‐2 complex formation.

Accuracy and precision in DM intake prediction models for lactating dairy cows
AnimalPredicting the daily DM intake (DMI) of lactating dairy cows is an essential criterion for formulating diets according to requirements, which limits the application of safety margins in economically and environmentally sensitive nutrients, such as energy,

Nitric oxide‐forming nitrite reductases in the anaerobic ammonium oxidizer Kuenenia stuttgartiensis
FEBS Open Bio, EarlyView.Anammox bacteria remove fixed nitrogen from their environment via anaerobic ammonium oxidation (anammox) with nitrite as electron acceptor and dinitrogen gas as product. The first anammox step is the conversion of nitrite to nitric oxide by nitrite reductase.
