White-tailed deer response to vehicle approach: evidence of unclear and present danger. [PDF]

PLoS ONE, 2014
The fundamental causes of animal-vehicle collisions are unclear, particularly at the level of animal detection of approaching vehicles and decision-making. Deer-vehicle collisions (DVCs) are especially costly in terms of animal mortality, property damage,

Limitations on Animal Flight Performance [PDF]

Journal of Experimental Biology, 1991
ABSTRACT Flight performance seems to change systematically with body size: small animals can hover and fly over a wide range of speeds, but large birds taxi for takeoff and then fly over a narrow speed range. The traditional explanation for this is that the mass-specific power required for flight varies with speed according to a U-shaped

Heterozygous loss‐of‐function alleles associate the conserved 3′‐5′ exoribonuclease EXOSC10 with hypersensitivity to the anticancer drug 5‐fluorouracil

Molecular Oncology, EarlyView.
EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.

Sex-related interannual plasticity in wing morphological design in Heliconius charithonia enhances flight metabolic performance.

PLoS ONE, 2020
Flight morphological variations and its consequences on animal performance are common in winged insects. In the butterfly Heliconius charithonia, sex-related differences in the wing morphological design have been described resulting in differences in ...

Adaptive Bird-like Genome Miniaturization During the Evolution of Scallop Swimming Lifestyle

Genomics, Proteomics & Bioinformatics, 2022
Genome miniaturization drives key evolutionary innovations of adaptive traits in vertebrates, such as the flight evolution of birds. However, whether similar evolutionary processes exist in invertebrates remains poorly understood. Derived from the second-

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Animalopters - towards a new dimension of flight mechanics [PDF]

Transport, 2002
Recently, it has been recognised that flapping wing propulsion can be more efficient than conventional propel­lers if applied to very small-scale vehicles, so-called MAVs (micro air vehicles).

Protective Effect of Methyl Sulfonyl Methane on the Progression of Age-Induced Bone Loss by Regulating Oxidative Stress-Mediated Bone Resorption

Antioxidants
Aging is associated with detrimental bone loss, often leading to fragility fractures, which may be driven by oxidative stress. In this study, the outcomes of comparing the differences among young, adult and aged C57BL/6J mice found that the trabecular ...
