US scientists have partially revived pig brains four hours after the animals were slaughtered.
The findings could fuel debate about the barrier between life and death, and provide a new way of researching diseases like Alzheimer’s.
The study showed the death of brain cells could be halted and that some connections in the brain were restored.
Scientists bring some functions in a pig’s BRAIN ‘back to life’ — four hours after the farm animal died„.
Scientists have been able to partially revive the brains of decapitated pigs that died four hours earlier in a groundbreaking study.
Experts used tubes that pumped a chemical mixture designed to mimic blood into the decapitated heads of 32 pigs to restore circulation and cellular activity.
Echoing Mary Shelley’s classic novel Frankenstein, billions of neurons began acting normally and the deaths of other cells was reduced over the course of six hours.
“Julie has been associated with SENS since its earliest days: she participated in the first workshop that I organised to discuss it, in 2000, and she was a co-author on the first SENS paper in 2002. We’re delighted to be funding her laboratory at the Buck Institute to explore new ways of eliminating neurofibrillary tangles from neurons of Alzheimer’s sufferers, and at UA2019 we will hear about their initial progress.” says Aubrey de Grey.

Scientists in the Yakutsk region of Siberia have managed to extract samples of liquid blood from a 42,000-year-old foal that was found embedded in permafrost back in 2018. The scientists are hoping to collect viable cells for the purpose of cloning the extinct species of horse.
The male foal was discovered in the Batagaika depression on August 11, 2018. Permafrost left the remains in remarkably good shape, raising hopes that its cells could be extracted. The specimen is thought to belong to an extinct species of horse known as Lenskaya breed (also known as the Lena horse), as the Siberian Times reported last year.
As the bitter strife between left and right, citizen and noncitizen, white and non-white attest, the greatest threat to humanity today goes beyond political and religious divides, economics, and psychiatric diagnoses. It goes beyond cultural conflicts and even the degradation of the environment—and yet it includes all of these.
To counter it, we call for a mobilization of mindfulness practices and dialogue groups on the scale of a public works program for human civility.
Dr. Greengard’s research described how cells react to dopamine, an important chemical messenger in the brain. His work provided the underlying science for many antipsychotic drugs, which modulate the strength of chemical signals in the brain.
“Our work shows the details of how dopamine produces these effects — in other words, what’s wrong in these diseases and what can be done to correct them,” Dr. Greengard said.
