L'olor de la mar / the smell of the sea

L'olor de la  mar / the smell of the sea | HacDosO | Scoop.it
The chances a cloud will remind you of the ocean are slim. Yet without oceans, there would be fewer clouds drifting above our heads. This is because these huge stretches of sea are full of tiny creatures that produce a gas known as dimethyl sulphide, or DMS, which under certain circumstances has the faculty of initiating the beginnings of a cloud. These creatures - algae or bacteria - do not synthesize DMS for sculpting clouds; DMS happens to be the side product of a metabolite known as dimethylsulfoniopropionate, or DMSP, that phytoplankton probably require for buoyancy or protection, or perhaps even both. The air-borne DMS is responsible for the sometimes unpleasant pungent smell that is characteristic of the sea. The enzyme that is at the heart of this distinct sea scent was recently discovered in the marine phytoplankton Emiliania huxleyi and baptised DMSP lyase 1 - an algal enzyme that cleaves DMSP and in so doing releases the perfumed DMS into the earth's atmosphere.

Global Distribution of Outbreaks of Water-Associated Infectious Diseases

Global Distribution of Outbreaks of Water-Associated Infectious Diseases | HacDosO | Scoop.it
Author Summary Water is essential for maintaining life on Earth but can also serve as a media for many pathogenic organisms, causing a high disease burden globally. However, how the global distribution of water-associated infectious pathogens/diseases looks like and how such distribution is related to possible social and environmental factors remain largely unknown. In this study, we compiled a database on distribution, biology, and epidemiology of water-associated infectious diseases and collected data on population density, annual accumulated temperature, surface water areas, average annual precipitation, and per capita GDP at the global scale. From the database we extracted reported outbreak events from 1991 to 2008 and developed models to explore the association between the distribution of these outbreaks and social and environmental factors. A total of1,428 outbreaks had been reported and this number only reflected ‘the tip of the iceberg’ of the much bigger problem. We found that the outbreaks of water-associated infectious diseases are significantly correlated with social and environmental factors and that all regions are affected disproportionately by different categories of diseases. Relative risk maps are generated to show ‘hotspots’ of risks for different diseases. Despite certain limitations, the findings may be instrumental for future studies and prioritizing health resources.

Una tortuga babaua pon ous a la platja de l'Arrabassada de Tarragona

Una tortuga babaua pon ous a la platja de l'Arrabassada de Tarragona | HacDosO | Scoop.it
Es tracta de la primera posta de tortuga babauadocumentada en aquestazona
La nit del 25 d'agost una tortuga babaua (Caretta caretta) va sortir del mar i, després d'arrossegar-se platja endins, va exacavar un niu onva pondre89 ous.

No en sabem el perquè, ja que aquestes tortugues, quan són adultes, tornen a la platja on van néixer a pondre els seus ous i no hi ha documentada anteriorment cap posta en aquesta zona.

Els ous, per tal de ser protegits, van ser traslladats ahir 26 d'agost a una platja del Parc Natural del Delta de l'Ebre no accessible al públic, on s'espera neixin les tortuguetes entre finals d'octubre i primers de novembre.
