Introduction. Discovering novel enzymes is of interest in both applied and basic science. Microbial enzymes, which are incredibly diverse and easy to produce, are increasingly sought by diverse approaches. Literature. This review first distinguishes culture-based from culture-independent methods, detailing within each group the advantages and drawbacks of sequence- and function-based methods. It then discusses the main factors affecting the success of endeavors to identify novel enzymes through construction and functional screening of genomic or metagenomic libraries: the sampled environment, how DNA is extracted and processed, the vector used (plasmid, cosmid, fosmid, BAC, or shuttle vector), the host cell chosen from the available prokaryotic and eukaryotic ones and the main screening steps. Conclusions. Library construction and screening can be tricky and requires expertise. Combining different strategies, such as working with cultivable and non-cultivable organisms, using sequence- and function-based approaches, or performing multihost screenings, is probably the best way to identify novel and diverse enzymes from an environmental sample.

The presence of large amounts of exozodiacal dust around nearby main sequence stars is considered as a potential threat for the direct imaging of Earth-like exoplanets and, hence, the search for biosignatures (Roberge et al. 2012). However, it is also considered as a signpost for the presence of terrestrial planets that might be hidden in the dust disk (Stark and Kuchner 2008). Characterizing exozodiacal dust around nearby sequence stars is therefore a crucial step toward one of the main goals of modern astronomy: finding extraterrestrial life. After briefly reviewing the latest results in this field, we present the exozodiacal dust survey on the Large Binocular Telescope Interferometer (LBTI). The survey is called HOSTS and is specifically designed to determine the prevalence and brightness of exozodiacal dust disks with the sensitivity required to prepare for future New Worlds Missions that will image Earth-like exoplanets. To achieve this objective, the LBTI science team has carefully established a balanced list of 50 nearby main-sequence stars that are likely candidates of these missions and/or can be observed with the best instrument performance (see companion abstract by Roberge et al.). Exozodiacal dust disk candidates detected by the Keck Interferometer Nuller will also be observed. The first results of the survey will be presented. To precisely detect exozodiacal dust, the LBTI combines the two 8-m primary mirrors of the LBT using N-band nulling interferometry. Interferometric combination provides the required angular resolution (70-90 mas) to resolve the habitable zone of nearby main sequence stars while nulling is used to subtract the stellar light and reach the required contrast of a few 10-4. A Kband fringe tracker ensures the stability of the null. The current performance of the instrument and the first nulling measurements will be presented. [less ▲]

Recent ALMA images of HL Tau show gaps in the dusty disk that may be caused by planetary bodies. Given the young age of this system, if confirmed, this finding would imply very short timescales for planet formation, probably in a gravitationally unstable disk. To test this scenario, we searched for young planets by means of direct imaging in the L‧ band using the Large Binocular Telescope Interferometer mid-infrared camera. At the location of two prominent dips in the dust distribution at ˜70 AU (˜0.″5) from the central star, we reach a contrast level of ˜7.5 mag. We did not detect any point sources at the location of the rings. Using evolutionary models we derive upper limits of ˜10-15 M[SUB]Jup[/SUB] at ≤0.5-1 Ma for the possible planets. With these sensitivity limits we should have been able to detect companions sufficiently massive to open full gaps in the disk. The structures detected at millimeter wavelengths could be gaps in the distributions of large grains on the disk midplane caused by planets not massive enough to fully open the gaps. Future ALMA observations of the molecular gas density profile and kinematics as well as higher contrast infrared observations may be able to provide a definitive answer. [less ▲]

The hurricane winds are characterized by high speeds, at which the « drag crisis » regime of flow around cable is achievable. That is why, in the calculation of the wind-induced movement of the overhead transmission line during hurricane, it is important to represent the cable aerodynamic drag as Reynolds-dependent. In order to assess the behaviour and fatigue resistance of the transmission line conductor under hurricane conditions, the Reynolds-dependent drag coefficient was introduced in the SAMCEF Mecano finite-element software. To represent the hurricane wind loading, the turbulent, spatially non-uniform wind model was used. Results of comparative study of the smooth cable AERO-Z and the classical multistrand cable, including the percentage of load reduction offered to supporting structure, are presented. [less ▲]
