What happens when stars brawl? What do they leave behind? When stars are dying they take down everything and everything around them from asteroids to other stars. What is the YORP effect? How do some tiny solar particles destroy an asteroid? Spiraling out of control, asteroids get YORP-ed at the end of a star's life. When a star gets to the end of it's life, it may swell in size, taking out asteroids and nearby stars.

The Coronavirus family is a dangerous lot from SARS to MERS and Novel Coronavirus 2019. This week we look at the history of Coronavirus outbreaks, research into past infections and public health strategy. We do some fact checking on Coronavirus myths and fears. What lessons were learnt from the SARS outbreak of '03 that can help today in '20? How can turning off the cells recycling plant stop Coronaviruses in their tracks? What role does cell autophagy play in spreading or stopping MERS? What can we learn from the sequenced genomes of coronaviruses? How can tracking the ACE2 gene help people monitor the mutation of the coronavirus strains?

What can bacteria from an iron ore rich lake tell us about life on early earth? Have scientists finally solved a Carl Sagan paradox about life on early earth? When the earth was young, so was the sun, and that meant less light and heat. How did early life on earth survive if there was not enough sunlight to keep it warm? How did iron ore eating and secreting bacteria help lead to widespread life on our planet? How did micro organisms get enough oxygen to survive when the entire planet was frozen over? What can iron ore deposits tell us about life surviving when the entire planet was frozen over? Can life survive on a meteorite, the answer is surprising. How can a microbe be more suited to life on a meteorite than on earth?

Satellites can help save lives down on earth, by helping us better respond in disasters. When a flood, tsunami or other disaster strikes, satellites can help emergency responders get where they need to be as fast as possible. Satellites can track floods in near real time and help shave minutes of disaster response times. Finding your way in a flood or fire can be tricky, but satellites can help direct emergency responders. Satellites can help track critical infrastructure like bridges or roads as they age. When a bridge fails it can be a tragedy, but satellites can help give an early warning. When we dig big tunnels we can disturb structures and buildings, so how can we use satellites to avoid a disaster.

Plants play an important role in our environment, yet there is still so much more to understand. We often think of nature as a zero sum game, but older and younger plants can collaborate. When surviving in a harsh environment, the best results occur when old and young plants grow together. Photosynthesis seems simple, but understanding the intricacies of the mechanisms can help us boost crop yields. Regulating the amount of photosynthesis can help plants survive or thrive in changing climates. How do boreal forests help capture nitrogen from the air? What does an odd metal have to do with forests in Canada storing nitrogen?

Smart phones, computers, televisions and even children's toys are part of what makes our modern world so exciting. But these often rely on plastics and rare earth metals which are hard to recycle. Are there efficient ways to capture all those rare earth metals? How are rare earth metals in old phones recycled today, and can we make it better? Knowing which bin to put plastic in is difficult, so what if there was a more universal way to recycle plastics? How does turning plastic into a gas with the help of steam help create a circular plastic economy? How can some steam power help crack plastics back into their most basic forms? Is it possible to recycle plastics without to build whole new plastic refineries? Regulation is often playing catch up to making materials safe. Are the latest generation of 'safe' fire retardants any safer than those that came before?

Humans have been using micro-organisms like fungus and bacteria to help improve our food for millennia. Can we tame new wild species of fungus to help create new types of our favourite foods like cheese? Penicillin is mostly known for antibiotics but it also helps give Camembert its particular taste. What causes cheese to rapidly tame wild strains of fungus? We are not the only ones who use microbes to help our food. Ants help stop disease from destroying plants by spreading their own antibiotics. Ant base antibiotics help stop plant pathogens. Sometimes bacteria don't fight against each other but rather team up and work together. Survival of kindest rules for bacteria, which helps different strains work together to survive.

Capturing carbon is important for helping offset CO2 emissions and tackling climate changes. Farming has an important role to play in improving CO2 sequestration with the use of cover crops and compost. Forests are important carbon sinks too, but they are at risk releasing a lot of the trapped carbon if care is not taken to stop invasive species. Plus fertilisers have helped feed the planet but can leech out nitrogen into the environment, so how do we better manage and improve the nitrogen cycle.
