s Gravitational waves could prove the existence of the quark-gluon plasma By www.eurekalert.org Published On :: Thu, 30 Apr 2020 00:00:00 EDT (Goethe University Frankfurt) According to modern particle physics, matter produced when neutron stars merge is so dense that it could exist in a state of dissolved elementary particles. This state of matter, called quark-gluon plasma, might produce a specific signature in gravitational waves. Physicists at Goethe University Frankfurt and the Frankfurt Institute for Advanced Studies have now calculated this process using supercomputers. Full Article

s UBC researchers establish new timeline for ancient magnetic field on Mars By www.eurekalert.org Published On :: Fri, 01 May 2020 00:00:00 EDT (University of British Columbia) Mars had a global magnetic field much earlier -- and much later -- than previously known. Analysis of new satellite data found clear evidence of a magnetic field coming from a lava flow that formed less than 3.7 billion years ago, half a billion years after many people thought the Martian dynamo had ceased. The researchers also detected low-intensity magnetic fields over the Borealis Basin, believed to be one of the oldest features on Mars. Full Article

s Fly ash geopolymer concrete: Significantly enhanced resistance to extreme alkali attack By www.eurekalert.org Published On :: Wed, 06 May 2020 00:00:00 EDT (University of Johannesburg) Fly ash generated by coal-fired power stations is a global environmental headache, creating groundwater and air pollution from vast landfills and ash dams. The waste product can be repurposed into geopolymer concrete, such as precast heat-cured structural elements for buildings. However, a critical durability problem has been low resistance to extreme alkali attack. UJ researchers found that high temperature heat-treatment at 200 degrees Celsius can halve this harmful mechanism in fly ash geopolymer concretes. Full Article
