Harvard scientists uncover key allowing deadly viruses to replicate

Viruses are masterful invaders. They cannibalize host cells by injecting their genetic material, often making thousands of copies of themselves in a single cell to ensure their replication and survival. Some RNA viruses — viruses whose RNA, not DNA, carries their genetic information — insert their genetic material into cells as a single piece, while… Read More »

Chinese scientists give monkeys human brain genes in ‘morally risky’ experiment

Their brains may not be bigger than normal, but monkeys created with human brain genes are exhibiting cognitive changes that suggest they might be smarter — and the experiments have ethicists shuddering. In the wake of the genetically modified human babies scandal, Chinese scientists are drawing fresh condemnation from philosophers and ethicists, this time over… Read More »

A bizarre Frankenstein-style experiment has breathed life into the brains of pigs four hours after death. Scientists in the US restored circulation and cellular activity in 32 pig brains obtained from a meat-packing plant. While there was no evidence of reawakening awareness or consciousness, the revitalised brains were said to be “cellularly active”. The study… Read More »
