Deep inside the body, tiny mechanical microscope diagnoses disease

Posted: 14 Aug 2012 06:32 PM PDT

Tiny space age probes -- those that can see inside single living cells -- are increasingly being used to diagnose illness in hard-to-reach areas of the body.

Orbiter views NASA's new Mars rover in color

Posted: 14 Aug 2012 05:18 PM PDT

The first color image taken from orbit showing NASA's rover Curiosity on Mars includes details of the layered bedrock on the floor of Gale Crater that the rover is beginning to investigate.

Plants exhibit a wide range of mechanical properties, engineers find

Posted: 14 Aug 2012 09:20 AM PDT

From an engineer's perspective, plants such as palm trees, bamboo, maples and even potatoes are examples of precise engineering on a microscopic scale. Like wooden beams reinforcing a house, cell walls make up the structural supports of all plants. Depending on how the cell walls are arranged, and what they are made of, a plant can be as flimsy as a reed, or as sturdy as an oak.

Quark matter’s connection with the Higgs: Heavy ion collisions delve deeper into the origin of (visible) mass

Posted: 14 Aug 2012 09:14 AM PDT

You may think you've heard everything you need to know about the origin of mass. After all, scientists colliding protons at the Large Hadron Collider (LHC) in Europe recently presented stunning evidence strongly suggesting the existence of a long-sought particle called the Higgs boson, thought to "impart mass to matter." But while the Higgs particle may be responsible for the mass of fundamental particles such as quarks, quarks alone can't account for the mass of most of the visible matter in the universe -- that's everything we see and sense around us.

New process doubles production of alternative fuel while slashing costs

Posted: 14 Aug 2012 09:11 AM PDT

A new discovery should make the alternative fuel butanol more attractive to the biofuel industry. Scientists have found a way around the bottleneck that has frustrated producers in the past and could significantly reduce the cost of the energy involved in making it as well.

Closing in on the border between primordial plasma and ordinary matter

Posted: 14 Aug 2012 08:09 AM PDT

Scientists have observed first glimpses of a possible boundary separating ordinary nuclear matter, composed of protons and neutrons, from the seething soup of their constituent quarks and gluons that permeated the early universe.

Hearing the telltale sounds of dangerous chemicals

Posted: 14 Aug 2012 08:09 AM PDT

Researchers have developed a new chemical sensor that can simultaneously identify multiple nerve agents.

New research promises quiet cars -- even when hitting unexpected bumps in the road

Posted: 14 Aug 2012 08:09 AM PDT

New research featuring a mathematical model for quick-response, noise-cancellation designed to minimize sudden and unexpected noise caused by road hazards -- bumps or potholes for example -- has just been developed.

Graphene's behavior depends on where it sits: Materials beneath determine how it react chemically and electrically

Posted: 14 Aug 2012 07:03 AM PDT

Surprising new experiments show that a one-atom-thick material called graphene, a form of pure carbon whose atoms are joined in a chicken-wire-like lattice, behaves quite differently depending on the nature of material it's wrapped around.
