“#State-level R&D tax credits spur growth of new businesses: study” Credit: CC0 Public Domain Here’s some good news for U.S. states trying to spur an economic recovery in the years ahead: The R&D tax credit has a significant effect on entrepreneurship, according to a new study led by an MIT professor. Moreover, the study finds…
“#Study shows optical fields can modify electrons in metal” Coherent photoelectron spectroscopy of optical dressing. Credit: Nature Communications (2020). DOI: 10.1038/s41467-020-16064-4 Pittsburgh research coauthored by team from the Department of Physics and Astronomy reveals that optical fields have the ability to modify electronic properties of a solid. The paper, “Coherent multidimensional photoelectron spectroscopy of ultrafast…
“#Innovative model provides insight into the behavior of the black hole at the center of our galaxy” Sagittarius A*. This image was taken with NASA’s Chandra X-Ray Observatory. Credit: Public domain Like most galaxies, the Milky Way hosts a supermassive black hole at its center. Called Sagittarius A*, the object has captured astronomers’ curiosity for…
“#Bird feeding helps females more than males” Credit: Johan Nilsson A new study from Lund University in Sweden shows that female birds benefit more from extra food in the winter. If females receive additional food, they do not need to reduce their body temperature as much as they would have otherwise, and the chances of…
“#Creating a non-toxic alternative to colored smoke” Credit: imago images / Shotshop Colored smoke is increasingly employed as an element of spectacle in a broad spectrum of public events. However, the chemicals used for this purpose give rise to toxic by-products. LMU chemists have now developed a safe alternative. Colored smoke is an indispensable ingredient…
“#ATLAS Experiment searches for rare Higgs boson decays into a photon and a Z boson” Figure 2: Weighted Zγ mass distribution of events satisfying the H→Zγ selection in data. Events are weighted by the expected signal and background in a Zγ mass window containing 68% of the expected signal. The solid blue curve shows the…
“#Hot holes are key in a plasmon-induced reaction of oxygen molecules on silver surfaces” Chemists at RIKEN have discovered how plasmons generated by shining light at the gap between a gold tip and a silver surface and can break the bonds of oxygen molecules adsorbed on the surface.

“#Radioactive cloud over Europe had civilian background” The scientists carried out the isotope measurements using such air filters. Credit: Dorian Zok/LUH A mysterious cloud containing radioactive ruthenium-106, which moved across Europe in autumn 2017, is still bothering Europe’s radiation protection entities. Although the activity concentrations were innocuous, they reached up to 100 times the levels…
“#Health profession: Social interdependence in active learning evaluated by Delphi procedure” Credit: CC0 Public Domain Physicians must be competent collaborators with team members in order to practice medicine effectively. Health professional students have limited opportunities to work and learn together during the course of their medical education. Not only is it important for students to…
“#Where have the swans gone?” The research was only possible because of the code some swans carry. Sightings of these tagged animals – often by citizen scientists – offer insight into the whereabouts of individual swans and changes therein. In winter, the swans favour areas with an air temperature of 5.5 °C. Credit: Bart Nolet/NIOO-KNAW…
