Summary #704

Solar energy becomes biofuel without solar cells
  • Researchers have produced microorganisms that can efficiently create butanol using only carbon dioxide and solar energy.
  • They are cyanobacteria built to specialise in producing energy, developed with the help of synthetic biology and genetic modifications.
  • Cyanobacteria are the most efficient photosynthetic organisms on Eearth.
  • The modified bacteria is efficient enough that it could be used to produce fuel, or components for tyre rubber.
  • It could also potentially be used in industries with large greenhouse gas emissions to significantly reduce them.


  • Science Science (57) Reinforcement learning might be the best path to advanced AI, because it’s the same algorithm that brains use
  • Psychology Psychology (62) MDMA-assisted PTSD therapy significantly more effective than therapy without psychedelics
  • Cosmos Cosmos (28) Huge black hole found, shouldn’t even exist
  • History History (14) Humans survived off rodents in the mountains during the last ice age, study says
  • Society Society (63) Review of air pollution reduction measures shows that they have positive health outcomes
  • Medicine Medicine (59) Drink targeting DNA molecules inside bacterial cells might be helpful against antibiotic resistance
  • Technology Technology (65) Device from University of Hong Kong makes electricity from waste heat
  • Nature Nature (43) Single-cell organisms might be able to process information and make decisions
