Phobos LIFE (Living Interplanetary Flight Experiment)

The Planetary Society's Phobos Living Interplanetary Flight Experiment (Phobos LIFE) flew in the sample return capsule of the Russian Federal Space Agency's Phobos Grunt mission and was to have been a test of one aspect of the hypothesis that life can move between nearby planets within ejected rocks. Although the Phobos Grunt mission failed, we present here the scientific and engineering design and motivation of the Phobos LIFE experiment to assist with the scientific and engineering design of similar future experiments. Phobos LIFE flew selected organisms in a simulated meteoroid. The 34-month voyage would have been the first such test to occur in the high-radiation environment outside the protection of Earth's magnetosphere for more than a few days. The patented Phobos LIFE “biomodule” is an 88 g cylinder consisting of a titanium outer shell, several types of redundant seals, and 31 individual Delrin sample containers. Phobos LIFE contained 10 different organisms, representing all three domains of life, and one soil sample. The organisms are all very well characterized, most with sequenced genomes. Most are extremophiles, and most have flown in low Earth orbit. Upon return from space, the health and characteristics of organisms were to have been compared with controls that remained on Earth and have not yet been opened

Do horses recognize the difference between harsh tones and soothing tones when using voice as a reinforcer for learning a frightening task

When working with horses, it is frequently asserted that horses have an inherent understanding of harsh voice cues that would be used as reprimands versus soothing voice cues that may be used as positive reinforcers/calming modifiers. If horses are unable to understand this difference, handlers often make poor assumptions that potentially lead to unfair training. A total of 95 horses from 4 different locations in US and Europe were randomly assigned to either soothing voice treatment (SV; n=52) or harsh voice treatment (HV; n=43). The learning task involved horses of various breeds and ages learning to cross a tarpaulin. Methodology was standardised across locations. SV involved handlers saying \u201cgood horse\u201d in a soft, soothing manner whenever horses made forward progress toward the tarpaulin. HV involved saying \u201cquit it\u201d in a loud, harsh manner whenever horses made forward progress toward the tarpaulin. PRAAT software was used to assess similarities in vocal spectrograms of different handlers/treatments. Mean pitch for SV was 244.4\ub13.11 Hz and 275.1\ub12.01 Hz for HV; both well within the equine hearing range. Average intensity (loudness) for SV was 42.3\ub11.04 dB and 56.0\ub11.80 for HV. Contrary to our hypotheses, risk of failing the task (> 10 min to cross the tarpaulin for the 1st time) was not different between treatments (25% failures SV; 25.5% failures HV; p=0.55). Also, for those horses who did cross the tarpaulin, the total time to achieve calmness criterion (crossing with little/no obvious anxiety) did not differ between treatments (157.3\ub159.8 sec HV vs 245.8\ub143.5 SV, p=0.23. A breed difference was noted: Hot bloods=606.8\ub1145.9 sec vs Warm bloods=120.7\ub118.3 sec, p<0.01. Polar heart rate monitors were used on 68 horses. There was no difference between average HR of horses who crossed (84.7\ub13.9 bpm) vs those who failed (82.1\ub15.1) p=0.69. There was also no difference between HV horses (85.4\ub14.8 bpm) and SV horses (81.3\ub14.2) p=0.52

Health Disparities in Awareness of Physical Activity and Cancer Prevention: Findings from the National Cancer Institute's 2007 Health Information National Trends Survey (HINTS)

This national study examines differences between racial/ethnic groups on awareness of physical activity and reduced cancer risk and explores correlates of awareness including trust, demographic, and health characteristics within racial/ethnic groups. The 2007 Health Information and National Trends Survey (HINTS) provided data for this study. After exclusions, 6,809 adults were included in analyses. Awareness of physical activity in reduced cancer risk was the main outcome. Logistic regression models tested relationships. Non-Hispanic Blacks had a 0.71 (0.54,0.93) lower odds of being aware of physical activity in reduced cancer risk than non-Hispanic Whites. Current attempts to lose weight were associated with greater odds for awareness among non-Hispanic Blacks and Hispanics (p < .01). Among non-Hispanic Blacks, trust in traditional and Internet media was associated with greater odds of awareness (p < .01). This study is the first national study to examine racial/ethnic disparities in awareness of physical activity and cancer risk. Comparisons between racial/ethnic groups found Black-White disparities in awareness. Variables associated with awareness within racial/ethnic groups identify potential subgroups to whom communication efforts to promote awareness may be targeted
