Tech & Science Daily| Human cells grown in monkey embryos 'raise ethical concerns'

Researchers from the Salk Institute in California have produced what’s known as monkey-human chimeras, with human stem cells inserted in macaque embryos in petri dishes in the lab.

They say their work could pave the way in addressing the severe shortage in transplantable organs as well as help understand more about early human development, disease progression and ageing.

That’s according to researchers who say despite previous infection and the presence of antibodies, vaccination is still necessary to boost immune responses, prevent reinfection and reduce transmission.

Scientists say marine microbes could be the answer to replacing chemicals found in food, pharmaceuticals and beauty products.

We spoke to Professor Stephen Euston who coordinates an international team working on a project to replace synthetic, petroleum-based surfactants and emulsifiers with sustainable alternatives.

Google Earth’s had its biggest update in five years and hopes it’ll “ground debate” about climate change, wait for it - researchers have calculated the total T-rex population as 2.5 billion during the 2.4 million years the species stalked earth; Air pollution in China soars to severe levels as a giant cloud of sand rolls into Beijing, and, two friends have dined in 3D hologram form – fancy that.
