Road Repair, Potholes

Rapid road repair vehicle would fix potholes on the fly

A Sandia laboratory technician who dreamed of a bus-sized vehicle that would fix potholes as it drove over them now holds a patent on the idea.The automated system requires only a single driver instead of a crew, and is equipped with a global positioning system and cell phone so that really large hazards can be pinpointed in location, and called in.

Testing 'invisible' machines: Sandia's reliability tests advance future of micromachine systems

Work at Sandia to determine the reliability of microelectromechanical systems (MEMS) may mean that one day soon, most electronic devices will contain the micron-size machines. Their use may expand and change the electronics industry if they prove reliable.

Teen Marijuana Use Is Fueled By Change In Attitudes

Changes in student attitudes about marijuana, not a general rise in rebellious or delinquent behavior among the teen-age children of baby boomers, are driving recent increases in the use of the drug. One of the key findings from a University of Michigan analysis of the reasons behind historic fluctuations.

Study Identifies Gene That Promotes Nematode Infection in Soybeans

A team of scientists from four universities, including North Carolina State University, has identified a gene that allows soybean cyst nematodes (SCN) to attack and infect young soybean plants' roots, causing irreversible damage that can drastically reduce yields.

NC State Veterinarians Explore New Treatments for Dogs With Allergies

Researchers at North Carolina State University are looking at new ways to treat atopic dermatitis that are less stressful for dogs and more effective in the late phase of the disease, when steroids sometimes don't help.

Measuring bonds in a single molecule

Cornell University physicists have successfully measured the frequency at which atoms in a bond are vibrating in a single molecule of acetylene. The research for the first time provides a way to identify single molecules by their vibrational signatures and to study how their bonds change during chemical processes. It could lead to better understanding of how catalysts work and a new way to study biological molecules like DNA.

New Cosmic Ray Theory Sheds Light on Galactic Evolution Mystery

San Diego, Calif.--A team of astrophysicists announced today the development of a new theory to account for the source of heavy elements in cosmic rays, high-energy celestial particles that bombard the Earth at velocities near the speed of light.

Infants, Toddlers Sensitive To 'Grammatical Morphemes' That Make Language A powerful Communication System

Children are "born to speak" when it comes to a certain property that makes human language such an amazingly powerful communication system. Research shows how children depend on grammatical morphemes as cues to whether words are nouns or verbs, even though they omit these parts of language in their own speeech when they first start to talk.

Nest-Cam puts swallow family on the web

Seemingly oblivious to the video camera in the ceiling of their home, a pair of tree swallows at the Cornell Laboratory of Ornithology are raising a family in full view of the World Wide Web. The birds at Birdsource on the WWW are the most public avian participants in the Cornell Nest Box Network.

Brightest object in universe observed by University of Washington astronomer

The brightest object yet observed in the universe has been discovered by a University of Washington astronomer and his colleagues. The quasar is 4 million-billion to 5 million-billion times brighter than the Sun and outshines the brightest galaxy by more than 100 times
