By classifying different types of cells in the spinal cord, neuroscientists have gained new insight into an evolutionary achievement millions of years in the making.
“We have to start thinking about how we can address the problem,” said Robin Bell, a professor of glaciology at Columbia University and the president-elect of the American Geophysical Union, a professional organization of more than 60,000 Earth scientists.
When permafrost warms and thaws, it releases carbon dioxide and methane into the atmosphere. As the global thermostat rises, permafrost, rather than storing carbon, could become a significant source of planet-heating emissions.
A team of researchers at Columbia University say it’s possible to use solar panels on the ocean surface to power devices that can produce hydrogen fuel from seawater.
