As the national debate intensifies around immigration, a new study from the University of California School of Global Policy and Strategy is challenging conventional wisdom about “brain drain” — the idea that when skilled workers emigrate from developing countries, their home economies suffer. Published in Science, the paper reveals high-skilled emigration from developing countries may actually boost economic development, human capital and innovation in migrants’ countries of origin. With the U.S. undergoing sweeping immigration policy shifts — which include tighter work visa rules, student visa restrictions and return migration barriers — the new research highlights how these changes will reverberate…

A research team led by Professor Randolf Pohl from the Institute of Physics at Johannes Gutenberg University Mainz (JGU) has achieved a significant breakthrough in determining fundamental properties of atomic nuclei. For the first time, the team conducted laser spectroscopy experiments on muonic helium-3 at the Paul Scherrer Institute in Switzerland. Muonic helium-3 is a special form of helium in which the atom’s two electrons are replaced by a single, much heavier muon. Yesterday, the results have been published in the journal Science. “Our experiments with muonic helium-3 provide the most accurate value to date for the charge radius of…

Researchers led by Maike Sander, Scientific Director of the Max Delbrück Center, have developed a vascularized organoid model of hormone secreting cells in the pancreas. The advance, published in Developmental Cell, promises to improve diabetes research and cell-based therapies. An international team of researchers led by Max Delbrück Center Scientific Director Professor Maike Sander has for the first time developed an organoid model of human pluripotent stem cell-derived pancreatic islets (SC-islets) with integrated vasculature. Islets are cell clusters in the pancreas that house several different types of hormone-secreting cells, including insulin-producing beta cells. Researchers in the Sander lab at the…
