From schools of fish and flocks of birds to microscopic synthetic particles, many systems in nature and the laboratory consist of individual units or agents that move by consuming energy. These systems are known as active ...
Inside the cell nucleus, genes must be turned on and off with precision to regulate biological processes. The first models of gene regulation were developed in the 1960s, yet modern science continues to uncover new layers ...
When Jasmin Imran Alsous peered down her microscope lens, she expected to see chaos—a mishmash of tangled cells. She was viewing the inside of a male fruit fly's sperm storage organ, using a powerful microscope at the CCBScope ...
Materials engineers have developed the ability to manipulate structure and matter at the nanoscale for solid-state alloys called intermetallics, making it possible to alter their properties for improved performance.
Superfluids are intriguing states of matter in which particles behave like a giant collective wave, allowing them to flow without any friction. When this fluid flows past a fixed obstacle at a velocity below a specific threshold, ...
Inside cells, certain functions are carried out by locally adjusting molecular composition. This condensation of material results in the formation of dense droplets that can dynamically rearrange. Because of this, interactions ...
For more than half a century, materials scientists have struggled with how to simulate the complexity of polymer materials. An individual chain can comprise tens of thousands of atoms, a melt or composite contains billions, ...
Certain epigenetic modifications can directly control how genetic material is packed in the nucleus, RIKEN researchers have shown. This has important implications for our understanding of how genes are expressed in different ...
Living cells are fundamentally nonequilibrium systems, meaning they constantly spend energy through seemingly one-way, irreversible processes, such as transcribing DNA into RNA, to keep life going. But how that irreversibility ...
Researchers at Rensselaer Polytechnic Institute (RPI) have created a new and unusual state of matter—known as a supersolid—by engineering how light and matter interact inside a nanoscale device. The work, published in Nature ...
