Quantum entanglement pushes optical clocks to new precision

By replacing single atoms with an entangled pair of ions, physicists in Germany have demonstrated unprecedented stability in an optical clock. Publishing their results in Physical Review Letters, a team led by Kai Dietze at the German National Metrology Institute, hope their

Nanodevice produces continuous electricity from evaporation

A nanodevice developed at EPFL produces an autonomous, stable current from evaporating saltwater by using heat and light to control the movement of ions and electrons. Previously, researchers in the Laboratory of Nanoscience for Energy Technology (LNET) in EPFL's School of

The environmental impacts of where your apples are grown

New research from Cranfield University has analyzed the environmental impact of fresh apples sold in the U.K., comparing the greenhouse gas emissions and blue water scarcity across domestic production and imports from Europe and the Southern Hemisphere. The study examined nine

Tin isotopes reveal clues to nuclear stability

Separated by an ocean and more than a decade, innovative experiments with 31 tin isotopes having either a surplus or shortage of neutrons show how neutrons influence nuclear stability and element formation. The experiments, conducted between 2002 and 2012 at Oak Ridge National

Exposing a hidden anchor for HIV replication

The tiny shell protecting the HIV virus resembles a slightly rounded ice cream cone, but there is nothing sweet about it. More than 40 million people worldwide live with AIDS because of this virus, and treatments must continually evolve as HIV mutates. During the acute stage of

Identifying priority Southern Ocean conservation hotspots

New research shows that maintaining and adopting proposed marine protected areas (MPAs) in the Southern Ocean could almost double the protection of genetic hotspots from 28% to about 54%. These actions would stave off an otherwise high likelihood of ecosystem collapse in the
