"A team of scientists on Wednesday reported that the #fossil belonged to a 160,000-year-old #Denisovan, a member of a lineage of mysterious, #Neanderthal-like humans that disappeared about 50,000 years ago." nytimes.com/2019/05/01/sci… #Sapiens #Tibet
1. "The new fossil demonstrates that #Denisovans were remarkably hardy, able to endure harsh conditions on the Tibetan plateau, at an elevation of 10,700 feet, with only simple stone tools."
2. "The find also suggests that these #Denisovans may have evolved genetic adaptations to high altitudes, and that living #Tibetans may have inherited those genes thanks to interbreeding between Denisovans and modern humans in prehistoric times."

This past Friday marked 33 years since the #Chernobyl disaster. The podcast Today in Focus with @GuardianAnushka from @guardian chose to mark the occasion by uncritically reporting on the extraordinary claims of @katebrownumbc about the health impacts of the disaster. Thread 👇
@GuardianAnushka @guardian @katebrownumbc 1. It is said that "extraordinary claims require extraordinary evidence" but @guardian now joins @sciencemagazine, @nature, @TheEconomist, @thesundaytimes and others in providing a platform for Brown's radical claims with a remarkable lack of critique.

@GuardianAnushka @guardian @katebrownumbc @sciencemagazine @nature @TheEconomist @thesundaytimes 2. Historian @katebrownumbc alleges that several intergovernmental and non-governmental organisations such as @UN, @WHO, @IAEA, @iaeaorg, @RedCrossEU and the UNSCEAR have conspired to cover up tens of thousands or hundreds of thousands of casualties resulting from the accident.

#climate twitter! I want to donate 10% of my 2019 income where it will do the most good to reduce emissions. Would love to hear your take on the most effective orgs (in this thread or private DM). Thanks! Ping @drvox @KHayhoe @Fisher_DanaR @AmyAHarder @LeehiYona @EricHolthaus
As I replied to @EricHolthaus- I'm aware of and inspired by @givingwhatwecan & @GiveWell work on global health/poverty; I personally want to support climate mitigation. I realize there's no one right answer, depends on theory of change etc; curious to hear different perspectives.
Esp. in climate arena where impact could be on different possible levels (eg X tons avoided from cookstoves vs Y tons #fossil CO2 kept in the ground vs systemic political or economic change)- curious to hear diverse range of theory of change or evidence of effectiveness.
