Fungal endophytes in perennial ryegrass are essential to New Zealand’s pastoral system due to anti-insect effects. However, endophytes also produce compounds which can be detrimental to animals. Furthermore, as these toxins have been detected in the milk and fat of animals grazing common-toxic (containing lolitrem B) or AR37 endophyte-infected herbage they could enter the human food chain. To assess the risk to human health mice were fed for 90 days with three dose rates of lolitrem B and of AR37. Parameters indicative of animal health were measured as well as chemical, hematological and histological analysis of samples collected on day 90. Since endophyte toxin residues have been detected in milk, they could be transferred from mother to offspring via breast milk. To evaluate possible effects on reproduction two complete generations of mice were fed lolitrem B or AR37. At the dose rates given no adverse effects were observed in either study. The 100-fold safety factor to allow the use of animal data in human health assessments was applied and by considering the concentrations of lolitrem B or AR37 metabolites which could be ingested by a consumer it is highly unlikely that they pose any risk to human health.

Without a doubt, a publicly verifiable data is required to ensure a strong, transparent and independent air traffic management performance review system. Community sourced data (such as ADS-B/Mode S provided by OpenSky Network and others alike) has been used to analyse different aspects of air traffic management. The main drawback of such ADS-B data is the lack of crucial pieces of information that need to be inferred. On the other hand, Eurocontrol has used correlated position reports (CPRs) gathered from European Air Navigation Service Providers (ANSP) to conduct some of its actual/flown trajectory oriented performance analysis. The availability and the granularity of the CPRs vary between Eurocontrol Member States, making it difficult to perform accurate wide-scale studies. Using the strengths of both data sources would obviously result in great benefits. This paper describes the first step in creating a pan-European Flight Table (FT) and its supporting reference trajectories (RT). It is expected that the resulting dataset will be made available for the general public and that the work will continue to improve in scope and accuracy. Full article

This article, by noticing Augustine’s constant questioning, shows that he often talks about not knowing and about his need for God’s help to know more. It is therefore better to see how he identifies the mystery than to focus on his answers, because he too recognizes his limits. His intellectual prowess can be seen more clearly when he “names the mystery” than by thinking that he has solved it. Full article
