Natural Defense: Blood vessels battling cancer cells

MIT scientists have discovered that endothelial cells, which line the blood vessels, secrete molecules that suppress tumor growth and keep cancer cells from invading other tissues, a finding that could lead to a new way to treat cancer.

One word of advice...PLASTICS

Later this year, Hewlett-Packard researchers say, they expect to deliver to the U.S. Army a working prototype of what they're calling a "Dick Tracy wristwatch" - a lightweight, wearable device that soldiers in the field can use to view digital maps and other data on a flexible plastic screen that won't shatter or crack like glass.

FLEXIBLE DISPLAYS:

-Advantages: Flexible plastic displays can be thinner, lighter and more durable than glass, which can lower manufacturing costs, increase product life and make new designs possible.

-Applications: First will likely be smart phones, tablets and notebook computers. It could eventually be used in clothing, wall displays and other products that can be curved or rolled.

-Challenges: Requires new manufacturing processes and transistor materials. Hewlett-Packard is working on a method for imprinting and etching spools of plastic film; others are working with sheets of plastic temporarily bonded to glass.
