Period was previously thought to be ice-free
Arlington, Va.-Scientists using cores drilled from the New Jersey coastal plain have found that ice sheets likely caused massive sea level change during the Late Cretaceous Period -an interval previously thought to be ice-free. The scientists, who will publish their results in the March-April issue of the Geological Society of America (GSA) Bulletin, assert that either ice sheets grew and decayed in that greenhouse world or our understanding of sea level mechanisms is fundamentally flawed.
Led by Kenneth Miller of Rutgers University, the scientists examined cores from Ocean Drilling Program Leg 174AX, an onshore extension of an offshore expedition. They found indications that sea level changes were large (more than 25 meters) and rapid (occurring on scales ranging from thousands to less than a million years) during the Late Cretaceous greenhouse world (99- 65 million years ago).

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
