Nel 2012 dopo una serie di vittime anche straniere, il governo cinese aveva sospeso gli esperimenti clinici con cellule staminali e vietato il loro uso terapeutico. Non era servito a nulla, scrive David Cyranovski<\/a>,<\/p>\n

Since then, however, many rogue stem-cell clinics have\u00a0continued to operate<\/a>, while stem-cell scientists with valid research agendas have waited for a way to move forward.<\/em><\/p>\n

Adesso sono state pubblicate le regole<\/p>\n

The new measures outline requirements for such studies, including obtaining patients\u2019 informed consent and using clinical-grade stem cells that have been approved by an independent body. They say that stem-cell clinical studies can be carried out only at authorized hospitals, and they forbid the hospitals from charging recipients or advertising. Researchers who want to do pilot studies… will need to register with the health ministry with documentation showing that there are sufficient animal studies to support trials in humans and that they are using certified cell lines verified by independent evaluation.<\/em><\/p>\n

Come tre anni fa:<\/p>\n

The penalties for breaking the rules are not yet clear, although a senior health-ministry official has pledged to use them to clean up the stem-cell field in China.<\/em><\/p>\n

Solita promessa, ma:<\/p>\n

Douglas Sipp, who researches stem-cell policy at the RIKEN Center for Developmental Biology in Kobe, Japan, says that the mechanism laid out for clinical studies looks pretty similar to those in other countries, and more rigorous than some. But he worries that the measures might not apply to military hospitals, or to private clinics affiliated with military hospitals, which have in the past fallen outside health-ministry jurisdiction in China.<\/em><\/p>\n

\nTheir task is enormous. The destruction by Islamist terrorist group ISIS of sites such as the ancient Assyrian city of Nimrud has commanded most headlines, but its embrace of organized looting is just as great a threat. The collapse of civil society in Syria and Iraq has left hundreds of archaeological sites unguarded and susceptible to looting, encroachment and neglect.<\/em><\/p>\n

the FDA rejected the idea that it had a gender bias. It also warned that rare sudden drops in blood pressure and a poorly understood interaction with alcohol are outstanding concerns for Addyi. Incredibly, Sprout\u2019s alcohol-interaction study included<\/strong> 23\u00a0men and only 2 women.<\/strong> As part of its approval, the FDA is requiring Sprout \u2014 which Canadian drug maker Valeant bought for US$1\u00a0billion two days after Addyi\u2019s approval \u2014 to run three more studies on alcohol interaction after the drug goes on sale.<\/em>

Al congresso dell’Ecological Society of America,\u00a0Daniel Cressey<\/a> e Diana Hoag<\/a> hanno raccolto esempi di ecologia urbana, che temperano \u00a0un po’ il riscaldamento globale e che si potrebbero importare, mutatis mutand<\/em>i.

\u00a0Diseases spread by ticks are on the rise around the world, spurred by a combination of factors, including shifting climates and population sprawl into rural areas. Reported cases of Lyme, the most common US tick-borne illness, have nearly tripled in the country since 1992, although some of the increase could be due to heightened awareness. Lyme is also a growing problem in parts of Europe, Mongolia and China. Yet as bad as it is, there are nastier threats on the rise. In parts of Africa, the Middle East, Asia and southern Europe, ticks can spread Crimean\u2013Congo haemorrhagic fever, which is fatal in 40% of cases. <\/em><\/p>\n

Here we demonstrate a new regime of PWFAs <\/em>(plasma wakefield accelerators, ndr)\u00a0where particles in the front of a single positron bunch transfer their energy to a substantial number of those in the rear of the same bunch by exciting a wakefield in the plasma. In the process, the accelerating field is altered\u2014\u2018self-loaded\u2019\u2014so that about a billion positrons gain five gigaelectronvolts of energy with a narrow energy spread over a distance of just 1.3 metres. <\/strong><\/em><\/p>\n

\u00a0In the spring of 2014, the author began to notice tanker-jets quite often producing white trails across the cloudless blue sky over San Diego, California. The aerosol spraying that was happening with increasing frequency was a relatively new phenomenon there. The dry warm air above San Diego is not conducive to the formation of jet contrails, which are ice condensate. By November 2014 the tanker-jets were busy every day crisscrossing the sky spraying their aerial graffiti.<\/em><\/p>\n

A San Diego l’aria \u00e8 secca perch\u00e9 essendo calda inibisce l’evaporazione dell’acqua dal mare antistante<\/a>, ovvio.<\/p>\n

The author presents evidence that toxic coal combustion fly ash is the most likely aerosolized particulate sprayed by tanker-jets for geoengineering, weather-modification and climate-modification purposes and describes some of the multifold consequences on public health.<\/em><\/p>\n
