\nUn editoriale<\/a> e un reportage tornano sulla rissa nazionale tra pro e anti-vax a proposito dell’epidemia di morbillo in USA, per ridimensionarla:<\/p>\n

\u00a0But by global standards, it is a tempest in a teapot: as of 6\u00a0February, measles had struck 121\u00a0people in 17\u00a0states and the District of Columbia.<\/em>
\nThose numbers are unremarkable. Since October, a measles outbreak has affected more than 370 people in Germany; it saw almost 1,800 cases in 2013 and more than 1,600 in 2011. The Philippines had more than 50,000 cases in 2014. The United Kingdom had only 137 cases last year, but in both 2012 and 2013 it had close to 2,000.<\/em><\/p>\n

Declan Butler <\/a>fornisce altri dati<\/p>\n

China saw 107,000 people infected last year, and the Democratic Republic of the Congo (DRC) had 89,000 cases in 2013. The proportion of people who die varies depending on where you are.<\/em><\/p>\n

Nei papers molta genetica e scienza dei materiali, come al solito. Per ora ho letto:<\/p>\n

– \u00a0quello <\/a>di Paola Caselli del Max Planck et al. sui parti multipli di stelle da un singolo sistema, quattro addirittura, che avrei fatto rientrare nell’anno della luce
\n– e quello<\/a> di Miguel Martinez-Boti et al., un’altra ricostruzione paleo-climatica\/oceanografica basata su isotopi di boro, un altro omaggio al grande Cesare Emiliani<\/a>:<\/p>\n

Here we apply the boron isotope pH proxy in planktic foraminifera to two sediment cores from the sub-Antarctic Atlantic and the eastern equatorial Pacific as a more direct tracer of oceanic CO2 outgassing. We show that surface waters at both locations, which partly derive from deep water upwelled in the Southern Ocean, became a significant source of carbon to the atmosphere during the last deglaciation, when the concentration of atmospheric CO2 was increasing. This oceanic CO2 outgassing supports the view that the ventilation of a deep-ocean carbon reservoir in the Southern Ocean had a key role in the deglacial CO2 rise, although our results allow for the possibility that processes operating in other regions may also have been important for the glacial\u2013interglacial ocean\u2013atmosphere exchange of carbon.<\/em><\/p>\n

Commento di Katherine Allen <\/a>sulle implicazioni per i modelli climatici odierni.<\/p>\n

In tema: <\/strong>
\n– Kahan et al. pubblicano un paper in comunicazione della scienza, sulla percezione dei rischi climatici quando si parla di geoingegneria (bozza gratis<\/a>). Poi me lo studio ma la cosa interessante del loro sondaggio \u00e8 che non trovano un “moral hazard”:<\/p>\n

we found that subjects exposed to information about geoengineering were slightly more concerned about climate change risks than those assigned to a control condition.<\/em><\/p>\n

– da Real Climate, articolo <\/a>finto ingenuo di Rasmus Benestad sull’ennesima cantonata del Telegraph, gli fa eco Dana Nuccitelli <\/a>sul Guardian<\/em>;<\/p>\n

– il delizioso lagomorfo si occupa <\/a>del sondaggio, anch’esso vittima di gremlin a quanto sembra, di Richard Tol.<\/p>\n

\nPerch\u00e9 nella UE non \u00e8 sempre una buona idea approvare un farmaco solo perch\u00e9 \u00e8 autorizzato dalla FDA. Charles Seife, sul JAMA<\/a><\/em>:<\/p>\n

Fifty-seven published clinical trials were identified for which an FDA inspection of a trial site had found significant evidence of 1 or more of the following problems: falsification or submission of false information, 22 trials (39%); problems with adverse events reporting, 14 trials (25%); protocol violations, 42 trials (74%); inadequate or inaccurate recordkeeping, 35 trials (61%); failure to protect the safety of patients and\/or issues with oversight or informed consent, 30 trials (53%); and violations not otherwise categorized, 20 trials (35%). Only 3 of the 78 publications (4%) that resulted from trials in which the FDA found significant violations mentioned the objectionable conditions or practices found during the inspection. No corrections, retractions, expressions of concern, or other comments acknowledging the key issues identified by the inspection were subsequently published<\/em>.<\/p>\n","protected":false},"excerpt":{"rendered":"
