Airborne DNA reveals predictable spatial and seasonal dynamics of fungi

Fungi are among the most diverse and ecologically important kingdoms in life. However, the distributional ranges of fungi remain largely unknown as do the ecological mechanisms that shape their distributions1,2. To provide an integrated view of the spatial and seasonal dynamics of fungi, we implemented a globally distributed standardized aerial sampling of fungal spores3. The vast majority of oper

Seasonal progression and differences in major floral resource use by bees and hoverflies in a diverse horticultural and agricultural landscape revealed by DNA metabarcoding

Gardens are important habitats for pollinators, providing floral resources and nesting sites. There are high levels of public support for growing ‘pollinator-friendly’ plants but while plant recommendation lists are available, they are usually inconsistent, poorly supported by scientific research and target a narrow group of pollinators. In order to supply the most appropriate resources, there is

A machine-learning approach clarifies interactions between contaminants of emerging concern

Humans and biotas are exposed to a cocktail of contaminants of emerging concern (CECs), but mixture regulation is lagging behind. This is largely attributed to inadequate experimental data of mixture risk; revealing intricate interactions among CECs in mixtures with random combinations remains a formidable challenge. Here, we propose a new framework comprised of 5,720 lab tests of mixture risk for

Real-Time Near-Field mmWave Measurements Using Screen-Printed Metasurfaces and IR Camera

This paper elaborates on a technique for rapid real-time imaging of millimeter wave (mmWave) power density over surfaces of several wavelengths in size. The approach involves utilizing a screen-printed metasurface equipped with elements designed for absorption of mmWaves, along with an infrared camera to monitor temperature changes due to the absorption. By modulating the transmitted signal and ap

Risk Factors and Outcomes of Acute Kidney Injury After Cardiac Surgery : A Retrospective Observational Single-Center Study

BACKGROUND: Acute kidney injury (AKI) following cardiac surgery is a well-described phenomenon, usually associated with hemodynamic changes ultimately leading to ischemic injury to the kidneys. In this study, we assessed the occurrence of AKI in a cohort of patients undergoing elective cardiac surgery at a single center.METHODS: Patients undergoing elective cardiac surgery (coronary artery bypass

Dynamics in the Heritability of Leadership Role Occupancy: Evidence from A Three-Wave Twin Sample

Studies show that genetics matter in who becomes a leader. However, we know little about the dynamic properties of the heritability of leadership emergence or how genetics might interact with environmental conditions to shape leadership emergence. We track leadership role occupancy at three time points among a cohort of 1,079 Danish twin pairs over ten years. Our results suggest that genetics matt

The Failure of Diplomacy and Protection in Syria

This chapter argues that the international community’s response to the Syrian civil war was a failure of resolute diplomacy. It first recounts how a popular uprising was brutally suppressed by the Bashar al-Assad government’s military forces, sparking a ‘new war’ where many of the protagonists have more to gain from war than peace. It then considers the diplomatic strategies pursued by regional an

A single formant explicates the ubiquity of “meow”

Across languages, the species–typical vocalization by domes-tic cats (Felis catus silvestris) is transcribed similarly, typicallycorresponding to [miau:] or [waU:]. Such consistent and ubiqui-tous cross-linguistic transcription is apparently onomatopoetic.However, in humans, these qualities make unique use of thetongue; in comparison, most nonhuman mammals do not ap-pear to employ their tongues wh

High sperm deoxyribonucleic acid fragmentation index is associated with an increased risk of preeclampsia following assisted reproduction treatment

OBJECTIVE: To study the association between sperm deoxyribonucleic acid fragmentation index (DFI) and the odds of preeclampsia and other adverse perinatal outcomes after in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) treatment.DESIGN: A prospective cohort study including infertile couples undergoing conventional IVF or ICSI treatment and their children. Data regarding pre

MCU proteins dominate in vivo mitochondrial Ca2+ uptake in Arabidopsis roots

Ca2 + signaling is central to plant development and acclimation. While Ca2 + -responsive proteins have been investigated intensely in plants, only a few Ca2 + -permeable channels have been identified, and our understanding of how intracellular Ca2 + fluxes is facilitated remains limited. Arabidopsis thaliana homologs of the mammalian channel-forming mitochondrial calcium uniporter (MCU) protein sh

Acute severe hepatitis of unknown etiology in children : A mini-review

The emergence of acute, severe non hepA–E hepatitis of unknown etiology (ASHUE) has attracted global concern owing to the very young age of the patients and its unknown etiology. Although this condition has been linked to several possible causes, including viral infection, drugs and/or toxin exposure, the exact cause remains unknown; this makes treatment recommendation very difficult. In this revi

Monkeypox : Immune response, vaccination and preventive efforts

Infectious threats to humans are continuously emerging. The 2022 worldwide monkeypox outbreak is the latest of these threats with the virus rapidly spreading to 106 countries by the end of September 2022. The burden of the ongoing monkeypox outbreak is manifested by 68,000 cumulative confirmed cases and 26 deaths. Although monkeypox is usually a self-limited disease, patients can suffer from extre
