In the sea slug's defense against lobsters, confusion is key

...ed this novel chemical defense "phagomimicry." The stickiness of the slug's secretions appears to contribute to long-lasting effects on the target despite the aqueous environment, enhancing the effectiveness of the slug's defense. Cynthia E. Kicklighter, Shkelzen Shabani, Paul M. Johnson, and Charles D. Derby:...

Viral protein helps infected T cells stick to uninfected cells

... sticky and adhere to other T cells. The greater stickiness happens because the p12 viral protein causes special adherence proteins found on the surface of T cells to cluster in large groups ?something that normally happens when T cells touch to communicate with one another during an immune response.

MIT engineers probe spiders' polymer art

...n two rapidly moving glass plates. They tested its stickiness by pulling it apart, like taffy, between two metal plates. The magic that makes silk so strong, the researchers discovered, happens while it flows out of the spider's gland, lengthens into a filament and dries. Engineering Nature The key to s...

Neuron cell stickiness may hold key to evolution of the human brain

The stickiness of human neurons may have been a key factor in why the human brain evolved beyond the brains of our primate relatives. In a study comparing the genomes of humans, chimpanzees, mice and other vertebrates, researchers at the U.S. Department of Energy's...
