Physicist Fatima Ebrahimi at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) has published a paper showing that magnetic reconnection — the process in which magnetic field lines snap together and release energy — can be triggered by motion in nearby magnetic fields. By running computer simulations, Ebrahimi gathered evidence indicating that the wiggling of atomic particles and magnetic fields within electrically charged gas known as plasma can spark the onset of reconnection, a process that, when it occurs on the sun, can spew plasma into space.

FSU scientist's findings on carbon cycle feed climate research
A Florida State University researcher is taking a deep dive into the carbon cycle and investigating how carbon moves from the ocean surface to greater depths and then remains there for hundreds of years.
Trees supplement income for rural farmers in Africa
Trees may be easy to spot on the plains of Africa but they are often overlooked as a source of income for farmers. A University of Illinois study shows trees on farms may help reduce rural poverty and maintain biodiversity.
Catalyst adds fluorine-containing groups to make new compounds
Drugs that contain one or more fluorine atoms tend to be more stable, more powerful, and easier for the body to absorb. For those reasons, drug developers would like to be able to incorporate fluorine or a fluorine-containing unit known as trifluoromethyl into new experimental drugs, but this has been very difficult to do.
Now, a team of chemists at MIT and Boston College has discovered a new type of catalyst that can incorporate a trifluoromethyl group within a variety of organic molecules. The availability of these exceptionally efficient and selective catalysts should allow researchers to rapidly generate potential new fluorinated drugs, including antibiotics and anticancer agents, for testing.
Spanish scientists create a 3D bioprinter to print human skin
Scientists from the Universidad Carlos III de Madrid (UC3M), CIEMAT (Center for Energy, Environmental and Technological Research), Hospital General Universitario Gregorio Marañón, in collaboration with the firm BioDan Group, have presented a prototype for a 3D bioprinter that can create totally functional human skin. This skin is adequate for transplanting to patients or for use in research or the testing of cosmetic, chemical, and pharmaceutical products.
Improving prognoses for a sustainable future
Computer models play a significant role in environmental policy, but offer only a partial picture of the industrial system
Whether it’s electric automobiles, renewable energy, carbon tax or sustainable consumption: Sustainable development requires strategies that meet people’s needs without harming the environment. Before such strategies are implemented, their potential impact on environment, economy, and society needs to be tested.
