Grazie a uno studio internazionale a cui ha partecipato l’Istituto per la dinamica dei processi ambientali del Consiglio nazionale delle ricerche (Idpa-Cnr), pubblicato su The Cryosphere, è stato rilevato che il ghiaccio più profondo e antico presente sul Monte Ortles (3.905 m, sulle Alpi orientali, a 37 chilometri dal luogo del ritrovamento dell’Uomo del Similaun), ha cominciato a muoversi per la prima volta dai tempi dell’Uomo del Similaun, 7.000 anni fa. Le prime carote di ghiaccio estratte indicano come il ghiacciaio più elevato dell’Alto Adige abbia cominciato una fase di accelerazione del movimento che non avrebbe precedenti nel periodo osservato. Le prove vengono dagli strati più profondi, datati con la tecnica del carbonio 14, e da misurazioni condotte nel foro di perforazione mediante un inclinometro, strumento in grado di rilevare anche minimi movimenti glaciali. “Queste carote di ghiaccio offrono l’eccezionale opportunità di studiare le caratteristiche dell’atmosfera quando l’Uomo del Similaun viveva in questa regione, in modo da poter conoscere anche l’ambiente ed il clima in cui era immerso”, dichiara Carlo Barbante, direttore dell’Idpa-Cnr di Venezia.

A Japanese research group has used a new technology that identifies multiple fish species populating local areas by analyzing DNA samples from seawater, and proved that this method is accurate and more effective than visual observation.

 

This research was carried out as part of the Japan Science and Technology Strategic Basic Research Programs by a group including Academic Researcher YAMAMOTO Satoshi (Kobe University Graduate School of Human Development and Environment), Associate Professor MASUDA Reiji (Kyoto University), Professor ARAKI Hitoshi (Hokkaido University), Professor KONDOH Michio (Ryukoku University), Project Assistant Professor MINAMOTO Toshifumi (Kobe University Graduate School of Human Development and Environment), and Adjunct Associate Professor MIYA Masaki (Head of Department of Ecology and Environmental Sciences, Natural History Museum and Institute, Chiba).

Though placid enough to be managed by humans, yaks are robust enough to survive at 4000 meters altitude. Genomic analyses by researchers of Ludwig-Maximilians-Universitaet (LMU) in Munich show that yak domestication began several millennia ago and was promoted by repeated crosses with cattle.

Antimicrobial drugs play a critical role in the treatment of diseases, their use is essential to protect both human and animal health. However, antimicrobials are often misused for treatment and prevention of diseases in livestock sector, aquaculture as well as crop production. These actions are often associated with the potential risk of emergence and spread of antimicrobial resistant micro-organisms.
