A research team wanted to better understand how the forces between particles inside a material change. They discovered that by confining one-dimensional classical spin chains inside a mirror box cavity with light, they could force these magnetic particles to organize and undergo a phase transition. Their work provides the simplest exactly solvable examples showing that light can create new phase transitions with materials.

Magnetic nanocomposites could help shrink the components that power computer chips
When you think about making computer chips better, you probably think about transistors. My colleagues and I focused on a less visible part of the problem: the components that deliver power to those transistors. A chip needs more than electricity. It needs electricity supplied at

How competing reproductive needs shaped the evolution of liverworts
Liverworts reproduce through a life cycle involving two distinct stages. First, sperm fertilize eggs in the presence of water, producing embryos that develop into spore-producing structures called sporophytes. These structures then produce spores that can disperse and grow into n

Plants may experience 'optical illusions' that affect their direction of growth
A new study from Tel Aviv University reveals how plants, despite having neither a brain nor a nervous system, integrate light coming from multiple directions to determine where to grow. The researchers show how this process emerges from local sensing across the stem, without the
