Lagrange Point

What kicked off early life on earth? Organic chemistry and early life need the right minerals to be present and accessible. What helped unlock early minerals on earth like phosphorous to kick start life? Lightning strikes seem rare, but they're much more frequent than meteorites. Early life on Earth could have been helped along through lightning strikes and meteorites. DNA, RNA and Proteins are locked in a complex dance, but which came first. DNA can't replicate without the help of protein and RNA, so how did we develop DNA in the first place? Is it possible for RNA to replicate on it's own?

How does RNA work to protect your brain and keep it safe after a traumatic event? Micro RNA can play an important role in healthy brain development. Without key micro RNA, the development of the brain can run out of control. Without key microRNA, your can develop neurodevelopmental disorders. Without oxygen your neurons starve, so how can you protect them?  How can you use mRNA to make neurons more resilient and recover after a lack of oxygen? Getting proteins across the blood brain barrier is tricky, so can they be snuck in via mRNA? Using mRNA, you can produce proteins to add brain recovery right where they're needed most.

Hydrogen fuel promises a cleaner future, but the methods to make it are often dirty. A new approach recycles and treats waste water with sunlight to efficiently produce hydrogen. A new electrolysis approach turns waste antibiotics into hydrogen fuel cells. Removing antibiotics and other pharmaceuticals from waster water can be tricky, but a new technique turns that into green energy. Aquaculture is growing rapidly, but it is leading to antimicrobial resistance? What contributes more to antimicrobial resistance - fish farms or waste water? Incorrectly managed waster water can lead to superbugs.

Can you find fresh water in the middle of the ocean? What happens when a geyser of fresh water erupts from the sea floor into the ocean? A sudden freshwater spring can radically change the ocean floor. How do plankton shells and coral help us monitor a changing climate? Life in the oceans can help sequester carbon. We can track the way the climate has changed in the past by studying strontium isotopes in seawater. Changing climates can impact life in shallow and deep water, which can lead to changes in the carbon cycle. Tiny creatures like copepods can have a huge impact on our ocean food web. How do tiny creatures like copepods gather in ephemeral ocean zephyrs. Tiny vortexs can act as a gathering place for tiny but important sea creatures.
