Australians have taken to solar energy, but much of the electricity they generate cannot be stored and is returned back to the grid. However, commercial residential battery systems are now available, with new technologies on the horizon.

Can Hookworms Cure Coeliac Disease?

Can Hookworms Cure Coeliac Disease?

By Paul Giacomin

Coeliac disease patients infected with hookworms can tolerate gluten-containing foods, revealing the potential for these parasites and their secretions to treat a range of inflammatory diseases.

A sequence of the world’s oldest rocks in the depths of the Mariana Trench indicates that both plate tectonics and life may have commenced on Earth 4.4 billion years ago.

Survival of the Different

When a simple ancestral population of bacteria is kept in a constant controlled environment, a rich mixture of types evolves rather than a single “winner”.

When a simple ancestral population of bacteria is kept in a constant controlled environment, a rich mixture of types evolves rather than a single “winner”.

By Tom Ferenci

If evolution is about survival of the fittest, why does diversity emerge instead of perfectly evolved organisms that are fit in all environments? Now the complex trade-offs that shape the evolution of diversity have been measured.

Viral diseases transmitted by mosquito bite are a major public health problem worldwide.

By Prasad Paradkar, Jean-Bernard Duchemin & Peter Walker

Understanding how mosquitoes protect themselves from the viruses they carry could lead to new ways of controlling the spread of viral diseases like dengue or yellow fever.

Single photons have weird yet useful behaviours, with applications ranging from secure communications to quantum computing. While current silicon photon sources often produce additional “noise photons” that interfere with these emerging technologies, new research has discovered a method to quieten this quantum chaos.
