Australian Research opens up new possibilities for hydrogen fuelled future.

Scientists show how using only water, iron, nickel and electricity can create hydrogen energy much more cheaply than before.

Hydrogen-powered cars may soon become more than just a novelty after a UNSW-led team of scientists demonstrated a much cheaper and sustainable way to create the hydrogen required to power them.

In research published in Nature Communications recently, scientists from UNSW Sydney, Griffith University and Swinburne University of Technology showed that capturing hydrogen by splitting it from oxygen in water can be achieved by using low-cost metals like iron and nickel as catalysts, which speed up this chemical reaction while requiring less energy.

During one of these phase transitions (which happened when the universe was less than a second old), the axions of string theory didn’t appear as particles. Instead, they looked like loops and lines — a network of lightweight, nearly invisible strings crisscrossing the cosmos.

This hypothetical axiverse, filled with a variety of lightweight axion strings, is predicted by no other theory of physics but string theory. So, if we determine that we live in an axiverse, it would be a major boon for string theory.

How can we search for these axion strings? Models predict that axion strings have very low mass, so light won’t bump into an axion and bend, or axions likely wouldn’t mingle with other particles. There could be millions of axion strings floating through the Milky Way right now, and we wouldn’t see them.

Happy New year everyone! We wanted to give you an inside look as to what happens on our Dr. Joe live calls that take place once a month. Here’s a moment from our last Dr. Joe live call.

⁣ Some of the subjects Dr. Joe may address: latest scientific discoveries; health and wealth; love and relationships; neuroscience and epigenetics; happiness and vitality; the quantum model of reality; how you can make great and lasting changes in yourself and your life!⁣

⁣ With his vast experience and deepening knowledge of how each one of us can unlock unlimited abilities and transform our lives for the better, these classes offer you a unique opportunity to continually learn and interact with Dr. Joe! If you want to take it a step further in the work, Dr. Joe live is a great way to deepen your understanding, keep you plugged into the community and interact with Dr. Joe personally.⁣.

Nuclear fusion, the process that powers our sun, happens when nuclear reactions between light elements produce heavier ones. It’s also happening — at a smaller scale — in a Colorado State University laboratory.

Using a compact but powerful laser to heat arrays of ordered nanowires, CSU scientists and collaborators have demonstrated micro-scale nuclear fusion in the lab. They have achieved record-setting efficiency for the generation of neutrons — chargeless sub-atomic particles resulting from the fusion process.

Their work is detailed in a paper published in Nature Communications (“Micro-scale fusion in dense relativistic nanowire array plasmas”), and is led by Jorge Rocca, University Distinguished Professor in electrical and computer engineering and physics. The paper’s first author is Alden Curtis, a CSU graduate student.
