Una Ricerca della Sapienza ha analizzato lo smalto dei denti da latte rinvenuti a Velia
Lo smalto prenatale, studiato in relazione con il successivo sviluppo postnatale, costituisce il principale oggetto di ricerca del progetto condotto da un team della Sapienza in collaborazione con il Museo delle Civiltà di Roma, l’Université di Toulouse III e l’University College London. La ricerca, realizzata per la Sapienza da Alessia Nava e coordinata da Alfredo Coppa nell’ambito del corso di dottorato in Biologia ambientale ed evoluzionistica, è pubblicata sulla prestigiosa rivista PLoS ONE.
I denti umani sono importanti archivi paleobiologici che raccontano la storia di un individuo; quelli decidui, la cui formazione comincia già dai primi mesi in utero, possono costituire l’unica finestra di conoscenza sullo sviluppo intrauterino, un momento cruciale nella vita, che ha inevitabili ricadute sulla salute anche in età adulta.
A oggi molti studi si sono focalizzati sulle porzioni di smalto dei denti decidui sviluppate dopo la nascita, ma è l’analisi delle porzioni prenatali che è cruciale nella conoscenza dello sviluppo intrauterino: permette infatti di identificare eventuali eventi stressanti e può rivelare informazioni utili circa lo stato di salute della madre durante la gravidanza.

Do Occupational Factors Affect Reproductive Health and Chronic Disease Risk for Nurses?

A prospective study of more than 20,000 nurses aged 20-45 years, 88% of whom had worked night shifts, reported their most common health issues, disease history, reproductive experiences, occupational exposures, and other lifestyle- and work-related factors. The study, which included 13% of all active Korean female nurses, is published in Journal of Women's Health, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. The article is available free on the Journal of Women's Health website until September 17, 2017.
The article entitled "The Korea Nurses' Health Study: A Prospective Cohort Study," is coauthored by Hyun-Young Park, MD, PhD and colleagues from Korea National Institute of Health, Ewha Womans University, Doowon Technical University, Hallym University, Yonsei University, and Seoul National University, Republic of Korea; Brigham and Women's Hospital, Harvard Medical School, and Harvard T..H. Chan School of Public Health, Boston, MA; and The Warren Alpert Medical School of Brown University and Brown University School of Public Health, Providence, RI.
Young victims of cyberbullying twice as likely to attempt suicide and self-harm, study finds
Children and young people under-25 who become victims of cyberbullying are more than twice as likely to enact self-harm and attempt suicide than non-victims. While perpetrators of cyberbullying are also more likely to experience suicidal thoughts and behaviours, researchers say. The study, which is a collaboration of a number of researchers from across the UK including the University of Birmingham looked at more than 150,000 children and young people across 30 countries, over a 21-year period. Their findings, published on open access in PLOS One, highlighted the significant impact that cyberbullying involvement (as bullies and victims) can have on children and young people. The researchers say it shows an urgent need for effective prevention and intervention in bullying strategies. Professor Paul Montgomery, University of Birmingham said: ‘Prevention of cyberbullying should be included in school anti-bullying policies, alongside broader concepts such as digital citizenship, online peer support for victims, how an electronic bystander might appropriately intervene; and more specific interventions such as how to contact mobile phone companies and Internet service providers to block, educate, or identify users. ‘
Organic waste and insects: animal feed of the future?

Right now, the European Union doesn’t have enough animal feed of its own to nourish livestock, forcing it to bring in supplies from beyond the bloc’s borders. To face this unsustainable dependency, researchers are looking for alternative protein sources. More than the 70 percent of the protein sources required by animals bred in the European Union are imported from non-EU countries. Soybean dominates the protein supply for animal feed. This dependency is costly, subjected to market fluctuations and price rises. The European Parliament adopted a resolution stating the urgency in replacing at least part of the imported feeding stuff with alternative sources, of EU origin. One of the exit-strategies investigated by researchers is reusing food waste to feed animals, with the help of low energy consumption technologies. Considering the huge amount of food waste generated in Europe, estimated to be 88 million tons each year, the project NOSHAN identified functional feeding ingredients derived from food waste that can be adapted to the needs of animals. A free food waste database has been created, which includes the molecular characterisation performed on 42 different waste streams.
