New candidate for raw material synthesis through gene transfer

Cyanobacteria hardly need any nutrients and use the energy of sunlight. Bathers are familiar with these microorganisms as they often occur in waters. A group of researchers has discovered that the multicellular species Phormidium lacuna can be genetically modified by natural transformation and could thus produce substances such as ethanol or hydrogen.

Major new paleoclimatology study shows global warming has upended 6500 years of cooling – EurekAlert

Process for ‘two-faced’ nanomaterials may aid energy, information tech

(DOE/Oak Ridge National Laboratory) A team led by the Department of Energy’s Oak Ridge National Laboratory used a simple process to implant atoms precisely into the top layers of ultra-thin crystals, yielding two-sided structures with different chemical compositions. The resulting materials, known as Janus structures after the two-faced Roman god, may prove useful in developing energy and information technologies.

Traffic density, wind and air stratification influence concentrations of air pollutant NO2

(Leibniz Institute for Tropospheric Research (TROPOS)) Traffic density is the most important factor for much the air pollutant nitrogen dioxide (NO2). However, weather also has an influence, according to a study by TROPOS, which evaluated the influence of weather conditions on nitrogen dioxide concentrations in Saxony 2015 to 2018 on behalf of LfULG. It was shown that wind speed and the height of the lowest air layer are the most important factors that determine how much pollutants can accumulate locally.

Scientists develop new tool to design better fusion devices

(DOE/Princeton Plasma Physics Laboratory) One way that scientists seek to bring to Earth the fusion process that powers the stars is trapping plasma within a twisting magnetic coil device shaped like a breakfast cruller. But the device, called a stellarator, must be precisely engineered to prevent heat from escaping the plasma core where it stokes the fusion reactions. Now, PPPL researchers have demonstrated that an advanced computer code could help design stellarators that confine the essential heat more effectively.

Geologists shed light on the tibetan plateau origin puzzle: an open-and-shut perspective

(Cactus Communications) Earth’s geographical surfaces have been formed over millions of years. Although various geological theories aim to explain their formation, the southern Tibetan Plateau is a region consisting of complex geological structures, whose origin has been unclear until now. In a new study published in Earth Science Frontiers, a team of geologists used an alternative “opening-closing” tectonic model to explain the origin of these structures.

Plant cell gatekeepers’ diversity could be key to better crops

(ARC Centre of Excellence for Translational Photosynthesis) Scientists have shed new light on how the network of gatekeepers that controls the traffic in and out of plant cells works, which they think is key to develop food crops with bigger yields and greater ability to cope with extreme environments.

Oak Ridge National Laboratory welcomes 6 new research fellows to Innovation Crossroads

(DOE/Oak Ridge National Laboratory) Oak Ridge National Laboratory welcomed six technology innovators to join the fourth cohort of Innovation Crossroads, the Southeast’s only entrepreneurial research and development program based at a US Department of Energy national laboratory.
