È difficile influenzare i politici con i risultati scientifici sul cambiamento climatico

L’esposizione alle previsioni dei modelli climatici ha meno effetto su policymaker e negoziatori che su un pubblico informato, secondo un articolo di Valentina Bosetti e co-autori. Ma il giusto formato di presentazione può migliorare l'efficacia delle previsioni.
Departure of migratory birds from stopover sites is hormone-controlled

Migratory birds often stop along their long journeys to replenish their fat stores. The purpose of these stopovers – rest and refuelling – is clear. To date, however, it had been unclear which physiological signals triggered the birds’ decision to continue their flight. A team led by researchers from Vetmeduni Vienna has now identified, for the first time, the hormone ghrelin as a signal for the birds’ brains. Ghrelin, which is known to be an appetite-regulating hormone in humans, was measured at high levels in satiated garden warblers. Moreover, birds injected with additional ghrelin exhibited decreased appetite and increased the highly active state of migratory restlessness. The results, which were published in the journal PNAS, confirm the hormonal influence on avian migratory behaviour and could even lead to an improved understanding of eating disorders among humans.
Fiscal incentives may help in fight to reduce gas emissions in developing countries

A study has found that fiscal policies introduced by governments in developing countries can have a significant effect on lowering harmful carbon emissions and help counties with fulfilling their commitments under the UNFCCC Paris Agreement.
The research, due to publish in the journal Climate Policy, used Brazil as a case study and found that even early-stage ad hoc measures could be key to reducing emissions in the efforts to meet greenhouse gas mitigation targets.

What Are the Best Treatments for Female Genital Mutilation?

A new review provides valuable insights for improving the health care of girls and women living with female genital mutilation. Published on February 6th, which is International Day of Zero Tolerance for Female Genital Mutilation, the article highlights what is currently known and what questions remain on how to address the needs of the millions of women and girls who are currently affected.

A study reveals plant-based diet of Europe’s oldest hominin

CENIEH participates in a study published in The Science of Nature which reveals the plant-based diet of Europe’s oldest hominin based on the analysis of dental calculus obtained at AtapuercaWed, 11/01/2017
The analysis of dental calculus obtained from the teeth of the mandible of an individual found at the Sima del Elefante site in Atapuerca (Burgos), dating back more than 1.2 million years, featured in a study on plant-based diet recently published in The Science of Nature journal, in which researchers from the National Research Centre for Human Evolution (CENIEH) Ruth Blasco and José Maria Bermúdez de Castro were involved.
Promiscuous lamprey found to conduct ‘sham matings’

Researchers at Hokkaido University have discovered that the nonparasitic lamprey Lethenteron kessleri mates repeatedly without releasing eggs, in a behavior termed “sham mating,” suggesting the possibility that females choose their mates while engaged in promiscuous mating habits.
Tecnologie per la diagnosi e la cura dei tumori

Mercoledi 8 febbraio si svolgerà il terzo appuntamento con ENEA per la Salute. L'incontro sarà focalizzato sul contributo dell’ENEA per lo sviluppo e la progettazione di tecnologie per la diagnosi e la cura dei tumori.
Nel corso della giornata verrà inoltre presentato il progetto TOP-IMPLART, un innovativo impianto d’irraggiamento con protoni per la cura dei tumori, che ENEA sta realizzando in collaborazione con altri istituti di ricerca (ISS, IFO). Saranno descritte sia le attività relative alla costruzione dell’acceleratore che le attività condotte per la caratterizzazione biologica e l’ottimizzazione di protocolli terapeutici nonché le loro prospettive cliniche.
Potential new cancer treatment activates cancer-engulfing cells

The engulfing function of the macrophage in response to cancer cells is inhibited by CD47-SIRPα interaction.
Macrophages(1) are a type of white blood cell that can engulf and destroy cancer cells. A research group led by Professor MATOZAKI Takashi, Associate Professor MURATA Yoji, and YANAGITA Tadahiko (Kobe University Department of Biochemistry and Molecular Biology, Division of Molecular and Cellular Signaling), discovered that by using an antibody(2) for a particular protein found on macrophages, the macrophage is activated, and cancer cells are effectively eliminated. This discovery could lead to the development of new cancer treatments. The findings were published on January 12 in the online version of JCI Insight.
