BLAZE: Bettering the lives of animals in zoo environments
Gemstone Team BLAZECaptivity can induce high levels of stress in zoo animals, leading to health and
behavioral problems that hamper conservation efforts, reduce the effectiveness of
education, and negatively affect animal welfare. Zoos employ environmental enrichment
to mitigate stress, but the effectiveness of various types of enrichment is poorly
understood. We surveyed enrichment practices at 39 zoos nationwide and then used
noninvasive fecal hormone analyses to monitor stress in three species of felids under different enrichment programs at two zoos. Baseline analyses at the National Zoological Park showed individual differences in stress hormone levels but no seasonal effects. Contrary to expectations, a novel enrichment program at Plumpton Park Zoo produced higher cortisol levels than a reduced enrichment program. Results suggest that novel objects that elicit active engagement may cause transient increases in stress hormones. Further long-term study is needed to elucidate whether this has a positive or negative effect on well-being
The Halo Stars in NGC 5128. III: An Inner-Halo Field and the Metallicity Distribution
We present new HST/WFPC2 (V,I) photometry for the red-giant stars in NGC 5128
at a projected distance of 8 kpc from the galaxy center, which probe a mixture
of its inner halo and outer bulge. The color-magnitude diagram shows an old
red-giant branch which is even broader in color than our two previously studied
outer-halo fields (at 21 and 31 kpc), with significant numbers of stars
extending to Solar metallicity and higher. The peak frequency of the
metallicity distribution function (MDF) is at [m/H] ~ -0.4, with even fewer
metal-poor stars than in the outer-halo fields. We find that the main features
of the halo MDF can be reproduced by a simple chemical evolution model in which
early star formation goes on simultaneously with an initial stage of rapid
infall of very metal-poor gas, after which the infall dies away exponentially.
A comparison with the MDF for the NGC 5128 globular clusters indicates that
there is a clear decrease of specific frequency (number of clusters per
unit halo light) with increasing metallicity, from S_N ~ 4-8 at [Fe/H] < -1.6
down to S_N = 1.5 at [Fe/H] > -1. This trend may indicate that globular cluster
formation efficiency is a strong function of the metallicity of the
protocluster gas.Comment: 25 pages, LaTeX, plus 20 figures as .jpg files; Astronomical Journal

COVID-19 symptoms at hospital admission vary with age and sex: results from the ISARIC prospective multinational observational study
Background:
The ISARIC prospective multinational observational study is the largest cohort of hospitalized patients with COVID-19. We present relationships of age, sex, and nationality to presenting symptoms.
Methods:
International, prospective observational study of 60â109 hospitalized symptomatic patients with laboratory-confirmed COVID-19 recruited from 43 countries between 30 January and 3 August 2020. Logistic regression was performed to evaluate relationships of age and sex to published COVID-19 case definitions and the most commonly reported symptoms.
Results:
âTypicalâ symptoms of fever (69%), cough (68%) and shortness of breath (66%) were the most commonly reported. 92% of patients experienced at least one of these. Prevalence of typical symptoms was greatest in 30- to 60-year-olds (respectively 80, 79, 69%; at least one 95%). They were reported less frequently in children (â€â18 years: 69, 48, 23; 85%), older adults (â„â70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each Pâ<â0.001). The most common atypical presentations under 60 years of age were nausea and vomiting and abdominal pain, and over 60 years was confusion. Regression models showed significant differences in symptoms with sex, age and country.
Interpretation:
This international collaboration has allowed us to report reliable symptom data from the largest cohort of patients admitted to hospital with COVID-19. Adults over 60 and children admitted to hospital with COVID-19 are less likely to present with typical symptoms. Nausea and vomiting are common atypical presentations under 30 years. Confusion is a frequent atypical presentation of COVID-19 in adults over 60 years. Women are less likely to experience typical symptoms than men
