<< Treating an addiction to a mind-altering substance with another mind-altering substance might seem counterintuitive, but more and more, researchers are finding ways that psychedelic drugs like psilocybin mushrooms and party drugs like ketamine could actually help people get over alcohol and drug addictions. >>

<< Proposed by futurist John Smart, the theory suggests that technological civilizations — and the Fermi paradox assumes there would be many by now — don’t colonize outer space (and thus flood the cosmos with signatures we could easily find). Instead, they move toward inner space by building vast digital realities on computers much smaller than we can detect. >>

# s-ageing: the long (and slow) life of Greenland shark (Somniosus microcephalus) ...

<< Greenland  sharks  live  at  least  as  long  as 400  years,  and  they  reach  sexual  maturity at  the  age  of  about  150,  a  new  study reports.  The  results  place  Greenland sharks  as  the  longest-lived  vertebrates  on Earth.  The  Greenland  shark  (Somniosus microcephalus)  is  widely  distributed across  the  North  Atlantic,  with  adults reaching  lengths  of  400  to  500  centimeters (13  to  16  feet).  The  biology  of  the Greenland  shark  is  poorly  understood,  yet their  extremely  slow  growth  rates,  at  about 1  cm per  year,  hint  that  these  fish  benefit from  exceptional  longevity. >>
