In the past, the value of climate records encoded in ocean sediment was limited by the inability to accurately date them.
Radiocarbon dating sediment contains too little uranium for uranium-thorium dating.
However, the researchers found sediments that are suitable and applied the technique. The dates reveal that the last two interglacial periods occurred right when we would expect if they were caused by variations in solar radiation reaching the earth. Further application of the approach will allow scientists to test theories of climate change. Possible Preventive for HIV in Newborns Early treatment with a protein that normally signals pregnancy in sheep may block the development of AIDS in babies born to HIV-infected mothers. Obviously, this benefits the consumer because you are going to be able to produce more meat for less cost.
