Non-Human Consciousness Exists Say Experts. Now What?

Non-Human Consciousness Exists Say Experts. Now What? | Generation Genetik | Scoop.it

Earlier this month, some of the leading scientists from around the world congregated at the Hotel Du Vin in Cambridge to discuss the evidence that has amassed over the years. The experts reached a unanimous decision that animals – specifically mammals and birds – are in fact conscious beings. Through advancements in brain imaging techniques such as fMRI and EEG machines, the scientists concluded that animals show a sufficient degree of characteristics that indicate they are not as non-human as some had believed. The official decision was reached late into the night after the Francis Crick Memorial Conference on July 7th.

 

Organized by Philip Low, CEO of NeuroVigil and inventor of the iBrain, the group consisted of 25 of the planet’s top minds on the mind, including honorary guest Stephen Hawking. The scientists discerned the key differences in human and animal brains, mainly found in the frontal cortex, do not play a role in the phenomenon we associate with consciousness. The decision does not in any sense define what consciousness is, which will be a debate that continues to rage on. But moving forward, there are many consequences to this finding that will need to be addressed as we look to develop a more humane relationship with animals.

A Programmable Dual-RNA–Guided DNA Endonuclease in Adaptive Bacterial Immunity

by

Martin Jinek, Krzysztof Chylinski, Ines Fonfara, Michael Hauer, Jennifer A. Doudna, Emmanuelle Charpentier

"Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated (Cas) systems provide bacteria and archaea with adaptive immunity against viruses and plasmids by using CRISPR RNAs (crRNAs) to guide the silencing of invading nucleic acids. We show here that in a subset of these systems, the mature crRNA that is base-paired to trans-activating crRNA (tracrRNA) forms a two-RNA structure that directs the CRISPR-associated protein Cas9 to introduce double-stranded (ds) breaks in target DNA. At sites complementary to the crRNA-guide sequence, the Cas9 HNH nuclease domain cleaves the complementary strand, whereas the Cas9 RuvC-like domain cleaves the noncomplementary strand. The dual-tracrRNA:crRNA, when engineered as a single RNA chimera, also directs sequence-specific Cas9 dsDNA cleavage. Our study reveals a family of endonucleases that use dual-RNAs for site-specific DNA cleavage and highlights the potential to exploit the system for RNA-programmable genome editing."

New study reveals the brain's mysterious switchboard operator - the pulvinar

New study reveals the brain's mysterious switchboard operator - the pulvinar | Generation Genetik | Scoop.it

Princeton University researchers have found that the pulvinar, a mysterious region deep in the human brain, acts like a switchboard operator to make sure that separate areas of the brain are communicating about the same external information most important to our behavior at a given moment. The pulvinar uses electrical impulses to synchronize and allow more effective communication between brain cells in the visual cortex, which processes visual information. The researchers produced neural connection maps that show the pulvinar's connection to these brain regions. In this scan, the pulvinar communicates with the occipital lobe (yellow) and the temporal lobe (red) individually, and with both (green).
