The global rise of “fake news” and the threat to democratic elections in the USA
PurposeSince the end of 2016, “fake news” has had a clear meaning in the USA. After years of scholarship attempting to define “fake news” and where it fits among the larger schema of media hoaxing and deception, popular culture and even academic studies converged following the 2016 US presidential election to define “fake news” in drastically new ways. The paper aims to discuss these issues.Design/methodology/approachIn light of the recent elections in the USA, many fear “fake news” that have gradually become a powerful and sinister force, both in the news media environment as well as in the fair and free elections. The scenario draws into questions how the general public interacts with such outlets, and to what extent and in which ways individual responsibility should govern the interactions with social media.FindingsFake news is a growing threat to democratic elections in the USA and other democracies by relentless targeting of hyper-partisan views, which play to the fears and prejudices of people, in order to influence their voting plans and their behavior.Originality/valueEssentially, “fake news” is changing and even distorting how political campaigns are run, ultimately calling into question legitimacy of elections, elected officials and governments. Scholarship has increasingly confirmed social media as an enabler of “fake news,” and continues to project its potentially negative impact on democracy, furthering the already existing practices of partisan selective exposure, as well as heightening the need for individual responsibility.

Free market environmentalism for the next generation
\"Free market environmentalism is an optimistic paradigm for linking dynamic environments with dynamic economies using property rights and markets to provide incentives for good resource stewardship. This book provides a new paradigm for environmentalism, offering examples of how free market environmentalism is working and confronting the limits of markets.\"--Provided by publisher.

Lion lords and sharing hyaenas: Carnivore guild dynamics around elephant carcasses
Megaherbivore carcasses represent sporadic but energetically rewarding resources for carnivores, offering a unique opportunity to study coexistence dynamics between facultative scavengers. South African fenced protected areas, such as Madikwe Game Reserve (Madikwe hereafter), host viable populations of large carnivores and high densities of elephants, Loxodonta africana. However, high carnivore densities can lead to potentially fatal interspecific encounters and increased competition, particularly around high‐quality trophic resources. This study explores the temporal partitioning and co‐detection strategies of carnivores at six elephant carcasses in Madikwe, aiming to understand how the increased carrion biomass available at elephant carcasses influences coexistence dynamics. Camera traps were deployed to monitor carcasses during two periods (2019 and 2020), revealing occurrences of six carnivore species. Carnivores, particularly black‐backed jackals, Lupulella mesomelas, (hereafter jackal), lions, Panthera leo, and spotted hyaenas, Crocuta crocuta, comprised 56.7% of carcass observations, highlighting their pivotal roles in scavenging dynamics. Pairwise co‐detection analysis demonstrated consistent association and shared peak activity periods between jackals and spotted hyaenas, indicating potential resource sharing. However, the minimal co‐detection rates between lions and other carnivores highlight their resource domination. There was some evidence of temporal partitioning between carnivores, with most species exhibiting earlier peaks in nocturnal activity to avoid temporal overlap with lions. This study emphasises the importance of elephant carcasses in the diet of multiple species and coexistence techniques utilised to exploit this ephemeral resource. As fenced protected areas become crucial for conserving intact carnivore guilds globally, further research into carnivore behavioural adaptations at carcasses is recommended to shed light on their coexistence strategies. Megaherbivore carcasses represent sporadic but energetically rewarding resources for carnivores and it is poorly understood how these carrion resources impact interspecific interactions. We studied elephant carcasses in Madikwe Game Reserve, South Africa, to investigate temporal partitioning and co‐occurrence between the carnivore guild. Co‐occurrence was high between some carnivores, suggesting aggressive interactions may be reduced by abundant food resources.

Evaluation of proxy-based millennial reconstruction methods
A range of existing statistical approaches for reconstructing historical temperature variations from proxy data are compared using both climate model data and real-world paleoclimate proxy data. We also propose a new method for reconstruction that is based on a state-space time series model and Kalman filter algorithm. The state-space modelling approach and the recently developed RegEM method generally perform better than their competitors when reconstructing interannual variations in Northern Hemispheric mean surface air temperature. On the other hand, a variety of methods are seen to perform well when reconstructing surface air temperature variability on decadal time scales. An advantage of the new method is that it can incorporate additional, non-temperature, information into the reconstruction, such as the estimated response to external forcing, thereby permitting a simultaneous reconstruction and detection analysis as well as future projection. An application of these extensions is also demonstrated in the paper.

Less-Tight versus Tight Control of Hypertension in Pregnancy
In this trial comparing less-tight control of hypertension (target diastolic blood pressure, 100 mm Hg) with tight control (85 mm Hg) among pregnant women, rates of pregnancy loss, high-level neonatal care, and serious maternal complications were similar between groups.
Almost 10% of pregnant women have hypertension; hypertension is preexisting in 1%, gestational hypertension without proteinuria develops in 5 to 6%, and preeclampsia develops in 2%.

Preexisting hypertension and gestational hypertension before 34 weeks are associated with an increased risk of perinatal and maternal complications.

Blood-pressure targets for women with nonsevere hypertension during pregnancy are much debated. Relevant randomized, controlled trials have been small and of moderate or poor quality; tight control (the use of antihypertensive therapy to normalize blood pressure) has been associated with maternal benefits (e.g., a decrease in the frequency of severe hypertension and possibly in . . .

The Ormdl genes regulate the sphingolipid synthesis pathway to ensure proper myelination and neurologic function in mice
Sphingolipids are membrane and bioactive lipids that are required for many aspects of normal mammalian development and physiology. However, the importance of the regulatory mechanisms that control sphingolipid levels in these processes is not well understood. The mammalian ORMDL proteins (ORMDL1, 2 and 3) mediate feedback inhibition of the de novo synthesis pathway of sphingolipids by inhibiting serine palmitoyl transferase in response to elevated ceramide levels. To understand the function of ORMDL proteins in vivo, we studied mouse knockouts (KOs) of the Ormdl genes. We found that Ormdl1 and Ormdl3 function redundantly to suppress the levels of bioactive sphingolipid metabolites during myelination of the sciatic nerve. Without proper ORMDL-mediated regulation of sphingolipid synthesis, severe dysmyelination results. Our data indicate that the Ormdls function to restrain sphingolipid metabolism in order to limit levels of dangerous metabolic intermediates that can interfere with essential physiological processes such as myelination.
