Arriva nei cinema il 23 febbraio, distribuito da Notorioius Pictures, il film “La marcia dei pinguini - il richiamo”, sequel dell’emozionante film già campione d’incassi in Italia nel 2005.

A dieci anni di distanza, il regista francese Luc Jacquet (regista anche de La volpe e la bambina) ci riporta tra i ghiacci con la magia delle riprese in alta definizione e l’utilizzo di innovative camere subacquee e droni, per una nuova avventura alla scoperta dell’Antartide. Le riprese si sono svolte lo scorso inverno per oltre due mesi, internamente in 4k. Protagonista un giovane pinguino che intraprende il suo primo viaggio insieme ai propri simili per una destinazione sconosciuta, guidato solo dall’istinto. Attraverso gli occhi e i ricordi di un pinguino anziano, lo spettatore potrà osservare da vicino questo momento decisivo nella vita del cucciolo, e seguire il giovane pinguino in tutto il suo straordinario viaggio con le grandi sfide che lo aspettano a ogni passo. A raccontare le avventure del giovane pinguino sarà il poliedrico Pierfrancesco Diliberto, in arte Pif, attore, conduttore, regista.

How can we minimise the pollutants in Europe’s bodies of water and provide a near-natural habitat for plants and animals? UFZ/André Künzelmann

The European Water Framework Directive (WFD) is due to be revised by 2019. The necessary work process is already in full swing and scientific research is providing important input. In a recent study under the auspices of the UFZ, an international team of researchers formulated recommendations designed to improve the monitoring, assessment and management of pollutants. The study was recently published in the journal Science of the Total Environment. The European Water Framework Directive has been in force since 2000. Its purpose is to ensure that rivers, lakes, coastal waters and groundwater achieve a ‘good status’ by 2027. This means that bodies of water should contain only minimal pollutants and should provide a near-natural habitat for plants and animals. Crucially, the European Water Framework Directive looks at bodies of water without regard to international borders – in the case of rivers, from source to estuary. “This is globally unique in this form. It’s the reason why many countries regard the European Water Framework Directive as an ideal model,” says environmental chemist Dr. Werner Brack from the UFZ.

(Fotolia) Surgical technique marks the start of a new chapter in the removal of benign tumours from the auditory nerve

A vestibular schwannoma is a benign tumour consisting of connective tissue and nerve tissue. It is still not known what causes it. 1 – 2 people in every 100,000 develop this type of tumour, which usually presses on the vestibular nerve and at the same time damages the auditory nerve. Up until now it has not been possible to remove the tumour and simultaneously restore the patient's hearing. This is exactly what Christoph Arnoldner of the Department of Ear, Nose and Throat Diseases at MedUni Vienna/Vienna General Hospital and Christian Matula (Department of Neurosurgery at MedUni Vienna/Vienna General Hospital) have now succeeded in doing for the very first time in Austria. This operation is also very rare worldwide.

Scientists at The Wistar Institute and Inovio Pharmaceuticals, Inc. have devised a novel DNA vaccine approach through molecular design to improve the immune responses elicited against one of the most important cancer antigen targets. Study results were published in the journal Molecular Therapy.

Cancer immunotherapy approaches, designed to harness the body’s natural immune defenses to target and kill cancer cells, are showing great promise for cancer treatment and prevention. DNA vaccines can induce immunity through the delivery by an intramuscular injection of a sequence of synthetically designed DNA that contains the instructions for the immune cells in the body to become activated and target a specific antigen against which an immune response is sought. This approach has proven effective in generating strong immunity against some infectious diseases as well as clearing neoplasia in patients with tumors caused by viral infection. The recent identification of tumor-associated antigens, or proteins that are specifically expressed by tumor cells and not by normal cells, has sparked the development of DNA vaccine approaches against some of these promising targets.

La Commissione europea denuncia l'Italia alla Corte di giustizia dell'Unione europea per mancata attuazione di disposizioni sulla sperimentazione animale nella normativa nazionale. La materia, che riscuote notevole interesse tra i cittadini, è disciplinata dalla direttiva 2010/63/UE sulla protezione degli animali utilizzati a fini scientifici, per cui il termine ultimo di recepimento nella normativa nazionale era il 10 novembre 2012. Su raccomandazione del Commissario per l'Ambiente Janez Potočnik, la Commissione chiede alla Corte d'imporre all'Italia una penale di 150 787 EUR al giorno.

Xylella fastidiosa in olive tree

Expert ecologists at the UK-based Centre for Ecology & Hydrology (CEH) have devised a scientific model which could help predict the spread of the deadly Xylella fastidiosa which is threatening to destroy Europe’s olive trees. The CEH scientists have created a model which is able to qualitatively and quantitatively predict how the deadly bacterial pathogen may spread as well as offer guidance on how buffer zones should be arranged to protect uninfected olive trees. The research, published in the journal Biological Invasions, highlights how Xylella fastidiosa is influenced by a range of insects – including spittlebugs – and the rate to which these vectors contribute to the potential spread of the disease across Europe and beyond.

The INM – Leibniz Institute for New Materials officially began its collaborative effort with the University of Namibia (UNAM) by holding a kick-off workshop. The aim of the joint project, NaMiComp, which is funded by the German Federal Ministry for Economic Cooperation and Development, is to analyze Namibia’s locally available natural resources and then use them as a basis for new materials for industrial applications. INM and UNAM are working together on the NaMiComp project in order to establish and strengthen research competence in materials science at UNAM. In the long term, the aim is to build an on-site materials science institute at the University of Namibia. The two-day long workshop, which was held at the INM, was the inaugural event for building this cooperation. Further multi-day workshops, reciprocal visits by experts, field surveys and learning cafés are set to follow.

Gene transfers are particularly common in the antibiotic-resistance genes of Streptococcus pneumoniae bacteria.

When mammals breed, the genome of the offspring is a combination of the parents' genomes. Bacteria, by contrast, reproduce through cell division. In theory, this means that the genomes of the offspring are copies of the parent genome. However, the process is not quite as straightforward as this due to horizontal gene transfer through which bacteria can transfer fragments of their genome to each other. As a result of this phenomenon, the genome of an individual bacterium can be a combination of genes from several different donors. Some of the genome fragments may even originate from completely different species.

A study from Stockholm University have now established what was previously suspected, that the high levels of brominated flame retardants measured in cats are from the dust in our homes. The study has been published in the journal Environmental Science & Technology. The study shows that cats are exposed to chemicals found in electronics and furniture, chemicals that become dust and can adversely affect health. It is the first time that this connection has been verified. In a previous study, the researchers demonstrated that brominated flame retardants were found in higher concentrations in the blood of cats that had developed Feline hyperthyroidism (hyperthyroidism in cats) compared to healthy cats. Now, new measurements of healthy cats establish their dust exposure. Paired samples were taken from the same household, i.e. they took both dust samples and blood samples at the same time.
