Chemical reactions have their own "impatient molecules." Unable to stay still even for a moment, they latch onto other molecules indiscriminately. Researchers have now found that even these molecules change where they "sit" and how far they roam depending on who their neighbors a

Chemical reactions have their own "impatient molecules." Unable to stay still even for a moment, they latch onto other molecules indiscriminately. Researchers have now found that even these molecules change where they "sit" and how far they roam depending on who their neighbors are. The findings are expected to help scientists make better medicines and materials by directing reactions only to the desired sites.

Customizable DNA labels can selectively guide drug carriers to cancer cells

Cells naturally send tiny packages to one another to share information. Researchers at Carnegie Mellon University have developed a simple, low-cost way to turn those packages into drug carriers that can deliver treatments directly to cancer cells, potentially improving effectiven

Scientists discover a secret glow in toxic fire salamanders

Researchers have discovered a surprising hidden ability in Europe's familiar black-and-yellow fire salamanders: they glow green and cyan under ultraviolet light. The mysterious fluorescence comes mainly from glands in their skin and their toxic secretions, which can continue glow

Scientists discover the immune system’s hidden sense of touch

Scientists at McGill University have discovered a surprising new ability of immune cells that could change how we understand long-term immunity. Researchers found that T cells can actually sense how stiff their surrounding tissues are, using these physical signals to help determi

Do spiders dream? Scientists just found a surprising clue

Scientists have discovered that spiders may sleep in ways surprisingly similar to humans, complete with distinct sleep stages and a dream-like REM state. Researchers at the University of Bonn studied the Australian jumping spider Portia fimbriata, a remarkably clever hunter known
