This week we look at unlikely partnerships that help sea creatures survive and thrive. What plays a crucial role inside a reef's ecosystem that is often overlooked? What's inside fish guts that help keep a reef healthy? Just how do fish 1000s of kms away end up with the same colonies of microbes? Feel like a tasty snack but stuck in the deep ocean vents, why not methane? How do microbes help worms eat methane?

Its a battle between Marine Mammals and Parasites. How does an opossum parasite start killing sea otters? In #2020MMM unexpected combatants can ruin your day, just like how opossum parasites are taking out sea otters. How does a parasite make a long journey from land to end up out at sea? Inside raw fish, parasitic worm populations are booming. This is bad news for marine mammals. Conserving marine mammals can be a delicate balancing act as parasite populations can also start to thrive.

How can we give better quality of life for those suffering from neurological conditions? Getting a concussion is bad enough, but why do people often develop epilepsy afterwards? What is the link between concussions and epilepsy? How can we effectively reduce the risk of epilepsy after a concussion? For certain epilepsy conditions in children, CBD can help reduce seizure risk, but what type is best? Is pharmaceutical or artisan CBD for children with epilepsy?

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?

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?

Do our eyes and ears process distance and location in a similar way? How does our brain discern differences in stimuli? What can we learn about pitch and rhythm from studying a remote Bolivian tribe?

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.

Is it possible to stop Alzheimer's in it's tracks? How does the formation of plaques on your brain cells lead to Alzheimer's. Does the your brain immune cells fighting back against plaques lead to Alzheimers? Amino acids in the brain tying themselves into knots, can lead to super strong sealed zippers forming which dry out proteins, damage neurons and eventually can lead to diseases like Alzheimer's. An enzyme missing a repair or two over 60 years can lead to build up of kinked amino acids chains which can lead to neuron-degenerative diseases. What causes a cell to eat itself? Well its actually a pretty healthy thing to do. If a brain cell doesn't eat itself at the right time, well it can lead to a whole bunch of diseases.

Growing enough food to feed the planet is a challenge that will only get harder as the climate changes. So how do farmers and scientists work together to make crops more sustainable, more resilient to disease, and use less herbicides? With genetic engineering, one of the worlds most important crops, rice, can be made even tougher. Using a two type bait gene, rice can be engineered to fight off fungus like rice blast. If you have to spray with herbicides, when should you do it? Well you need to pay attention to the circadian rhythm of the plants.

Your brain uses proteins synthesis and redundancy to help form and keep memories. Intricate biochemistry helps your neurons connect to each other to form new memories. Forming new memories is a sticky situation. Keeping them stuck together over time in a long lasting memory relies on protein synthesis. Its important not just to have strong connections between neurons to form memories, you also need spares. By having redundancy and backups it means that you can still remember a key memory if one of those connections fails.
