Demand for training life scientists in bioinformatics methods, tools and resources and computational approaches is urgent and growing. To meet this demand, new trainers must be prepared with effective teaching practices for delivering short hands-on training sessions—a specific type of education that is not typically part of professional preparation of life scientists in many countries. A new Train-the-Trainer (TtT) programme was created by adapting existing models, using input from experienced trainers and experts in bioinformatics, and from educational and cognitive sciences. This programme was piloted across Europe from May 2016 to January 2017. Preparation included drafting the training materials, organizing sessions to pilot them and studying this paradigm for its potential to support the development and delivery of future bioinformatics training by participants. Seven pilot TtT sessions were carried out, and this manuscript describes the results of the pilot year. Lessons learned include (i) support is required for logistics, so that new instructors can focus on their teaching; (ii) institutions must provide incentives to include training opportunities for those who want/need to become new or better instructors; (iii) formal evaluation of the TtT materials is now a priority; (iv) a strategy is needed to recruit, train and certify new instructor trainers (faculty); and (v) future evaluations must assess utility. Additionally, defining a flexible but rigorous and reliable process of TtT ‘certification’ may incentivize participants and will be considered in future.

Pulp and paper companies all over the world certify their environmental management systems assuming public commitments for the continuous improvement of their relationship with the environment. Once certified, they consider themselves having done their part. But is this enough? This work has been carried out with the clear intention of provoking the professionals who can give the much needed answers for the construction of environmental sustainability in the pulp and paper sector.

A risk assessment study of seven phthalates in paper diapers for newborn babies produced in Japan was performed. The diapers were purchased and the contents of the seven phthalates were determined and estimated amounts of exposure were calculated based on the eluted rate into artificial medium of urine or sweat, average weight of infants, and frequency of use. Di-2-ethylhexyl phthalate and di- n -butyl phthalate were detected in the topsheets and determined to be 0.6 μg/g and 0.2 μg/g, respectively. The daily estimated exposure volume was calculated to be in the range of 1.86 × 10 −10 –2.98 × 10 −6 mg/kg/day as follows: content of seven phthalates in the topsheet (0.1–1 μg/g) × eluted rate of phthalates into artificial sweat (0.0006–2.4%) × weight of the topsheet of a diaper (1.5 g) × the number of diapers used per day (12 sheets) × skin absorption rate (0.005–0.1)/average body weight (2.9 kg). For hazard assessment, we used 0.2–300 mg/kg/day for the seven phthalates based on the data available at international agencies. The margin of exposure to the seven phthalates was 6.71 × 10 4 –1.99 × 10 11 , indicating that the risk of exposure to phthalates from the diapers produced in Japan was negligible.
