What the octopus and the human brain have in common – Neuroscience News

Summary: Octopuses have a massively expanded repertoire of miRNAs in their neural tissue, reflecting development similar to that which has occurred in vertebrates. The results suggest that miRNA plays an important role in the development of complex brains. Source: MDC Cephalopods like octopus, squid, and cuttlefish are highly intelligent animals with complex nervous systems. In …

What could go wrong?! A 48,500-year-old Siberian virus is resurrected

The oldest known frozen, dormant virus in the world has been revived in a French lab, leading many to worry about the dangers of bringing ancient microbes to life. The virus was pulled from Siberian permafrost in far eastern Russia and is 48,500 years old, proving that viruses are incredibly resilient and able to survive …

MIT finds indoor humidity 'sweet spot' to reduce spread of COVID-19

MIT finds indoor humidity ‘sweet spot’ to reduce spread of COVID-19

An MIT study shows that keeping indoor humidity at an ideal location can reduce the spread of COVID-19. New research links very dry and very humid indoor environments to the worst COVID-19[feminine] First identified in 2019 in Wuhan, China, as COVID-19, or coronavirus disease 2019, (originally called "2019 novel coronavirus" or 2019-nCoV) is an infectious …

Giant dinosaurs and mammals through time. Credit: Nick Longrich Sixty-six million years ago, an asteroid hit Earth with the force of 10 billion atomic bombs and changed the course of evolution. The sky darkened and the plants stopped photosynthesising. The plants died, then the animals that fed on them. The food chain has collapsed. More …
