Using laser light to trap atoms in a checkerboard-like pattern, a team led by Princeton scientists studied how resistance — the loss of electrical current as heat — can develop in unconventional metals. The results may help explain how certain types of superconductors made from copper oxides are able to conduct electricity so efficiently. The…
130-Year-Old Brain Coral Reveals Encouraging News for Open Ocean
A 130-year-old brain coral has provided the answer, at least for the North Atlantic Ocean off the East Coast of the United States. By measuring the nitrogen in the coral’s skeleton, a team of researchers led by Princeton University found significantly less nitrogen pollution than previously estimated. The study was published online in the Proceedings…
