Hydrogen and methane provide raw energy for life at 'Lost City'

...bs across the nation will have access to satellite transmissions during the journey. Although nobody has yet found another field like Lost City, Kelley says she's 100 percent sure others exist because there are so many other places mantle rock has been thrust up through the seafloor, exposing it to seawater and s...

FSU biologists describe key role of signal-transcribing gene during cell cycle

... said Deng. The researchers traced the journey of transmissions originating from Notch ?? which carries information gleaned from other cells ?? following the signals down the Notch pathway as Cut linked them to the control of cell proliferation in the egg chambers, which they observed at different stages. When C...
