In copertina di Nature<\/em> c’\u00e8 un bellissimo – ok, de gustibus – axolotl, ma il sequenziamento del suo gigantesco genoma<\/a> era gi\u00e0 stato anticipato on-line. Sotto la copertina, c’\u00e8 anche un genoma pi\u00f9 modesto<\/a>, quello della planaria\u00a0Schmidtea mediterranea, <\/i>un vermiciattolo piatto che ondula nell’acqua semi-dolce lungo le coste del Mediterraneo, un eroe della ricerca in molti laboratori.<\/p>\n

we show that temperatures reconstructed from sub-fossil pollen from 642 sites across North America and Europe closely match simulations, and that long-term warming, not cooling, defined the Holocene until around 2,000 years ago. The reconstructions indicate that evidence of long-term cooling was limited to North Atlantic records.<\/p>\n

I modelli climatici sono piuttosto affidabili. S<\/a>orpresi?<\/p>\n

Un editoriale<\/span><\/a><\/span> celebra John Mercer che cinquant’anni fa aveva ricostruito le fusioni passate e previsto quella in corso nella Penisola occidentale antartica; un altro<\/span><\/a><\/span> spiega perch\u00e9 da questo mese gli autori di articoli, rassegne, opinioni ecc. su riviste del gruppo Nature<\/em> devono dichiarare anche i conflitti d’interesse non finanziario, le fonti di “bias” di cui sono consapevoli insomma.
\nA proposito di bias, Giorgia Guglielmi scrive<\/span><\/a><\/span> di una ricerca<\/span><\/a><\/span> prepubblicata su bioRXiv,<\/p>\n

Women lose out when reviewers are asked to assess the researcher, rather than the research, on a grant application, according to a study on gender bias. Training reviewers to recognize unconscious biases seems to correct this imbalance, despite previous work suggesting that it increased bias instead.<\/p>\n

Resistenza agli antibiotici, cont.<\/strong>
\nComplimenti ai colleghi indiani del Bureau of Investigative Journalism per aver rintracciato la provenienza della colistina, un antibiotico “di ultimo ricorso”, in “A game of chicken: how Indian poultry farming is creating global superbugs<\/span><\/a><\/span>”<\/p>\n

thousands of tonnes of veterinary colistin was shipped to countries including Vietnam, India, South Korea and Russia in 2016, the Bureau can reveal. In India at least five animal pharmaceutical companies are openly advertising products containing colistin as growth promoters.<\/p>\n

One of these companies, Venky\u2019s, is also a major poultry producer. […]\u00a0The Bureau bought 200g of Venky\u2019s-branded colistin – Colis V – over the counter from a poultry feed and medicines shop in Bangalore without a prescription. In Europe colistin is only available to farmers if prescribed by a vet for the treatment of sick animals.\u00a0Venky\u2019s is not breaking any laws in India by selling colistin and it said it will comply with any future regulatory changes…<\/p>\n

Su un tema affine, il Guardian\u00a0<\/em> riprende<\/span><\/a><\/span> i risultati di un sondaggio usciti<\/span><\/a><\/span> su PLoS One<\/em>,<\/p>\n

Mosquito nets are often distributed for free and anecdotal evidence of their use for other purposes has been controversial. Examples of nets being used to protect crops, to make chicken coops and even as wedding veils have led to\u00a0concern among medical professionals<\/a>\u00a0that public confidence in a life-saving programme could be undermined.<\/p>\n

The researchers found mosquito net fishing is seen across the globe. East Africa had the greatest concentration, but the practice was also seen from Bangladesh to the Philippines and Papua New Guinea. It was reported in both freshwater, as seen in Africa\u2019s great lakes and in Nepal, and in the sea, in west Africa…<\/p>\n
