Scientists from Tomsk Polytechnic University are developing a system for predicting the likelihood of forest fires. Using Gilbirinsky Forestry in the basin of Lake Baikal, they created a map of the territory and identified forest areas where the likelihood of fire emergency is the highest due to the vegetative conditions of the territory itself. This data will underpin a geographic information system (GIS) for predicting wildfires.

Moral lessons in children's television programs may require extra explanation
Children's television programming often contains moral lessons and examples of inclusiveness, but children may struggle to comprehend and transfer the situations presented on an animated production to their own lives, University of California, Davis, research suggests.

2018 to 2019 influenza season in U.S. was longest in 10 years
In the United States, the 2018 to 2019 influenza season was of moderate severity and lasted 21 weeks, according to research published in the June 21 issue of the U.S. Centers for Disease Control and Prevention Morbidity and Mortality Weekly Report.

Embryonic microRNA fuels heart cell regeneration, researchers show
By adulthood, the heart is no longer able to replenish injured or diseased cells. As a result, heart disease or an event like a heart attack can be disastrous, leading to massive cell death and permanent declines in function. A new study by scientists at the Lewis Katz School of Medicine at Temple University (LKSOM), however, shows that it may be possible to reverse this damage and restore heart function, even after a severe heart attack.

Reforming pharmacy benefit manager practices may lead to drug cost savings
Efforts to control health care costs in the United States often focus on the listed prescription drug prices, but a perspective published by the Journal of the American Medical Association suggests that unregulated pharmacy benefit manager practices also may contribute to escalating expenses.

PSI imaging helps with rocket launches
Rockets from the European Space Agency (ESA) fly into space with support from the Paul Scherrer Institute (PSI). Imaging carried out at PSI in cooperation with Dassault Aviation ensures the quality of certain components of the Ariane 5 and Vega launch vehicles. With the help of the neutrons generated at the neutron source SINQ, PSI researchers are screening so-called pyrotechnic components that are installed in the ESA rockets. These components, which act like fuse cords and igniters, ensure, among other things, that the booster rockets are dropped at the right hundredth of a second. The Ariane launch on 20 June took place with components that had been examined at PSI.

Advanced computational modeling of the gut for biodefense
The Nutritional Immunology and Molecular Medicine Laboratory (NIMML) has developed a high-resolution model of the gut immune system by using advanced computational systems. The new high-performance computing (HPC)-driven model of the gut predicts new emerging behaviors and responses to biological threats. The gut ecosystem includes trillions of interactions between host epithelial and immune cells, molecules (cytokines, chemokines and metabolites) and microbes is a massively and dynamically interacting network, similar to a multidimensional jigsaw puzzle with pieces that are constantly changing shape. These interactions with cooperativity and feedback lead to nonlinear dynamics and unforeseen emergent behaviors across spatiotemporal scales. The NIMML model of the gut facilitates discovering new knowledge within this complex system for biodefense applications.

Experiments with salt-tolerant bacteria in brine have implications for life on Mars
Salt-tolerant bacteria grown in brine were able to revive after the brine was put through a cycle of drying and rewetting. The research has implications for the possibility of life on Mars, as well as for the danger of contaminating Mars and other planetary bodies with terrestrial microbes. The research is presented at ASM Microbe 2019, the annual meeting of the American Society for Microbiology.

B chromosome first—mechanisms behind the drive of B chromosomes uncovered
The specific number of chromosomes is one of the defining characteristics of a species. Whilst the common fruit fly carries 8 chromosomes, the genome of bread wheat counts 42 chromosomes. In comparison, the human genome is made out of a total of 46 chromosomes. However, about 15% of all eukaryotic species additionally carry supernumerary chromosomes referred to as "B chromosomes". Other than the essential chromosomes of the genome, B chromosomes are expendable and often preferentially inherited. This leads to a transmission advantage for B chromosomes called "chromosome drive". To date, little knowledge exists about the mechanisms behind this phenomenon. Researchers from the Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) in Gatersleben have now been able to decipher the mechanisms behind the drive of B chromosomes in the goatgrass Aegilops speltoides. The novel insights in the workings of chromosome drive were recently published in New Phytologist.

Americans still eat too much processed meat and too little fish
A new study in the Journal of the Academy of Nutrition and Dietetics found that the amount of processed meat consumed by Americans has remained unchanged in the past 18 years, nor has their intake of fish/shellfish increased. In addition, one quarter of US adults are still eating more unprocessed red meat than the recommended level, and less than 15 percent meet the guidelines for fish/shellfish consumption. On a positive note, Americans are eating less beef and more chicken than they did 18 years ago, and in fact, for the first time, consumption of poultry exceeds that of unprocessed red meat.

How 5G could democratise the telecoms industry
A new, digital revolution might be about to hit us. Autonomous cars are driving our way, cities and companies are rapidly ramping up the use of sensors—also called the Internet of Things (IoT) – and virtual and augmented reality are making rapid strides.
