Abstract The current reliability of species identifications by the Nature Identification API (NIA) of the app ObsIdentify is tested with a Coleoptera (Insecta) sample set from Germany. Seventy-five photographic beetle records taken with a smartphone camera under “average user” conditions are analysed in terms of correctness of the app’s identification result on various taxonomic levels, the displayed confidence level of the identification and the time until validation of the results. More than 60% of samples were identified correctly at the species level, but only 53% were validated within a month. The mechanisms by which users can upload pictures of their observations to be identified by the artificial intelligence and the validation process by experts are briefly explained. Regional specifics and further opportunities for data usage as well as currently existing problems are discussed and improvements are suggested. The expert validation of records is identified as a huge quality advantage of the Obs-Services. They are generally found to be a promising tool for lay people and professional institutions, despite still existing deficiencies such as identification failure in mutilated specimens, cryptic and rare species, doubtful species rarity ratings as well as the still insufficient capacity of validation. Experts and institutions are encouraged to volunteer as validators and collaborators.

New Framework

Canadensys is an associate GBIF node in Canada, officially established as a node in 2014, but publishing data on GBIF since 2011. Since then, Canadensys has grown from nine institutions to a network of nearly 25 institutions that publish biodiversity data and we have migrated from an in-house explorer, to a Living Atlases (LA) framework. Canadensys publishes data curated or collected by Canadian universities, museums, as well as municipalities and non govermental organizations (NGOs). Establishing a new network can be challenging, but several resources and programs exist to help node managers and node participants initiate the publication process. Keeping an established network alive while continuing to grow and to develop new methods and technologies is also an important challenge, especially in a context where institutions are geographically separated across large distances, and where funds are scarce or mostly oriented towards highly innovative projects. With the aim to reach both established and new participants across Canada and from adjacent regions in the USA, and in order to help them to familiarize themselves with the new framework based on LA, we organized three workshops on data publication and data usage. Partially funded through a GBIF CESP project, this series of workshops was developed in partnership with international, regional and national partners such as iDigBio, OBIS Canada and GBIF Spain. The workshops helped new participants prepare and publish data, and allowed established publishers to enrich and update their resources on Canadensys and GBIF. The project also highlighted some of the challenges our network is facing, such as funding, infrastructure, human resources, and communication. Feedback from participants shows that the workshops were successfull in terms of capacity enhancement, giving knowledge and tools to data manager in order to prepare and publish standardize data, as well as to transfer that knowledge in their respective institutions. All materials and documentation developed during this project will be made available on Canadensys, allowing everyone interested to follow the curriculum. Sharing our experience will be useful for other nodes wanting to introduce the LA framework to their users and to enhance capacities in the network.

The major stumbling block on the internationalization of Traditional Chinese Medicine (TCM) is the lack of a complete set of quality standards that can be recognized and accepted by the international community through an objective and stringent validation process. That is to say, Chinese medicine needs to be standardized. Such a standardization is set by the state and the international regulation authorities who demand scientific proof on the safety, quality and efficacy of TCM. By using the simplest TCM formulation, Danggui Buxue Tang, we hereby present some existing problems and strategies to tackle this task based on the uniqueness of Chinese medicines.

Electron Microscopes

The era of atomic-resolution electron microscopy has finally arrived. In virtually all inorganic materials, including oxides, metals, semiconductors and ceramics, it is possible to image individual atomic columns in low-index zone-axis projections. A whole host of important materials’ problems involving defects and departures from nonstoichiometry on the atomic scale are waiting to be tackled by the new generation of intermediate voltage (300-400keV) electron microscopes. In this review, some existing problems and limitations associated with imaging inorganic materials are briefly discussed. The more immediate problems encountered with organic and biological materials are considered elsewhere.Microscope resolution. It is less than a decade since the state-of-the-art, commercially available TEM was a 200kV instrument with a spherical aberration coefficient of 1.2mm, and an interpretable resolution limit (ie. first zero crossover of the contrast transfer function) of 2.5A.

Scanning tunneling microscopy (STM) has recently been introduced as a promising tool for analyzing surface atomic structure. We have used STM for its extremely high resolution (especially the direction normal to surfaces) and its ability for imaging in ambient atmosphere. We have examined surfaces of metals, semiconductors, and molecules deposited on these materials to achieve atomic resolution in favorable cases.When the high resolution capability is coupled with digital data acquisition, it is simple to get quantitative information on surface texture. This is illustrated for the measurement of surface roughness of evaporated gold films as a function of deposition temperature and annealing time in Figure 1. These results show a clear trend for which the roughness, as well as the experimental deviance of the roughness is found to be minimal for evaporation at 300°C. It is also possible to contrast different measures of roughness.

Production Conditions

Innovators of in vitro meat (IVM) are convinced that this approach is the solution for problems related to current meat production and consumption, especially regarding animal welfare and environmental issues. However, the production conditions have yet to be fully clarified and there is still a lack of ethical discourses and critical debates on IVM. In consequence, discussion about the ethical justifiability and desirability of IVM remains hypothetical and we have to question those promises. This paper addresses the complex ethical aspects associated with IVM and the questions of whether, and under what conditions, the production of IVM represents an ethically justifiable solution for existing problems, especially in view of animal welfare, the environment, and society. There are particular hopes regarding the benefits that IVM could bring to animal welfare and the environment, but there are also strong doubts about their ethical benefits.
