Some single-celled organisms are known to transition to multicellularity during their lifetimes, usually either by cloning themselves or when many similar cells come together to form a larger ...

Biomolecular condensates were long believed to be simple liquid blobs inside cells. Researchers have now uncovered that some are actually supported by fine protein filaments forming an internal ...

The cerebral cortex, the brain's outermost region responsible for higher cognitive functions, depends on a highly ordered, layered structure. Its proper development requires newly generated neurons to ...

Human DNA constantly refolds in 3D space, and these looping dynamics regulate gene expression and cell identity.

Now, new research by Penn State scientists has revealed this vital process may be governed by a previously unknown molecular gatekeeper: a lattice‑like structure just beneath the surface of brain ...

Brain cells are constantly swallowing material from the fluid that surrounds them - signaling molecules, nutrients, even pieces of their own surfaces - in a process known as endocytosis that is ...

When a cell divides, it performs a feat of microscopic choreography—duplicating its DNA and depositing it into two new cells. The spindle is the machinery behind that process: It latches onto ...

Chronic sleep disruption doesn't just leave people tired and irritable. It may quietly undermine the gut's ability to repair itself, increasing vulnerability to serious digestive diseases. A new study ...

The demo: Keysight, Samsung achieved a live NR-NTN connectivity on a commercial-grade Samsung modem chipset in a demo at CES 2026. The test equipment: The trial used Keysight’s UXM 5G Wireless Test ...

Abstract: This paper addresses the challenges of “double-fading” effect and coverage limitations encountered by passive intelligent reflecting surface (IRS) by introducing a novel IRS architecture, ...

Cells may generate their own electrical signals through microscopic membrane motions. Researchers show that active molecular processes can create voltage spikes similar to those used by neurons. These ...

Schematic of an active cell membrane. In a typical active biological process, active proteins (shown in a variety of colors) in a cell membrane (shown in blue) interact with various biological ...
