New York: A joint team of US and Chinese scientists have, in breakthrough research, grown human cells in monkey embryos in a laboratory for up to 20 days. The development, which has sparked ethical debates, has implications for developing new models of human biology and disease.
Interspecies chimeras in mammals have been made since the 1970s, when they were generated in rodents and used to study early developmental processes. In the current study, detailed in the journal Cell, six days after the monkey embryos had been created, each one was injected with 25 human cells. The cells were from an induced pluripotent cell line known as extended pluripotent stem cells, which have the potential to contribute to both embryonic and extra-embryonic tissues.

US reliance on Russian oil hits record high despite souring ties
Russian and US relations have turned frosty again after a new round of US sanctions but when it comes to Moscow’s oil, US refiners are more dependent on it than ever.
Imports of Russian oil, which consists mainly of fuel oil feedstocks and some crude, recently reached a 10-year high as US refineries continue to ramp up runs as the economy starts to recover from COVID-19.
Russian oil imports as a share of US total oil imports hit a record high of 8% in January 2021, according to data from the US Energy Information Administration, up from 4% during 2018.
