ANAHEIM, March 28, 2011 — That dirty motor oil that comes out of your car or truck engine during oil changes could end up in your fuel tank, according to a report presented here today at the 241st National Meeting & Exposition of the American Chemical Society (ACS). It described development of a new process for recycling waste crankcase oil into gasoline-like fuel — the first, they said, that uses microwaves and has "excellent potential" for going into commercial use.

Icebergs cool and dilute the ocean water they pass through and also affect the distribution carbon-dioxide-absorbing phytoplankton in the Southern Ocean, according to a team of researchers from UC San Diego and the University of San Diego.
The effects are likely to influence the growth of phytoplankton in the Atlantic sector of the Southern Ocean and especially in an area known as "Iceberg Alley" east of the Antarctic Peninsula.
Psychological problems experienced during childhood can have a long-lasting impact on an individual's life course, reducing people's earnings and decreasing the chances of establishing long-lasting relationships, according to a new study.
Analyzing information about large group of British residents followed for five decades from the week of their birth, researchers found that family income was about one-fourth lower on average by age 50 among those who experienced serious psychological problems during childhood than among those who did not experience such problems.
COLUMBUS, Ohio – Engineers at Ohio State University have invented a new kind of nano-particle that shines in different colors to tag molecules in biomedical tests.
These tiny plastic nano-particles are stuffed with even tinier bits of electronics called quantum dots. Like little traffic lights, the particles glow brightly in red, yellow, or green, so researchers can easily track molecules under a microscope.
This is the first time anyone has created fluorescent nano-particles that can change colors continuously.
State laws and policies governing the storage and use of surplus blood samples taken from newborns as part of the routine health screening process range from explicit to non-existent, leaving many parents ill-informed about how their babies' left over blood might be used, according to a team led by a member of the Johns Hopkins Berman Institute of Bioethics, in collaboration with researchers from the University of Utah. A report on their analysis of the subject is published March 28 in the journal Pediatrics.
As fiber optic technology continues to advance, it faces challenges from both its physical properties and its use of infrastructure. One emerging high-speed solution being developed at Stevens Institute of Technology uses lasers to transmit data through readily available open space, with the potential of expanding past the limitation of fibers into a system known as optical free space communications. Dr. Rainer Martini has overcome a number of free space challenges to develop a high-speed communications technology that is not limited by a physical conductor.
University of Cincinnati research is investigating why a highly sophisticated civilization decided to build large, bustling cities next to what is essentially swampland. The research by UC Geography Professor Nicholas Dunning, a three-year, interdisciplinary project including David Lentz, professor of biological sciences, and Vern Scarborough, professor of anthropology, will be presented April 1 at the annual meeting of the Society for American Archaeology in Sacramento, Calif.
The performance took place on March 15 at the María Guerrero Theatre in Madrid, where the play "Woyzeck," by Georg Büchner could be enjoyed in the version by Juan Mayorga, under the direction of Gerardo Vera. This accessible staging has been promoted with the collaboration of the CESyA and the CDN, which for the first time ever in their theatres programmed a subtitled function for hearing impaired individuals, thanks to technological support from UC3M though a subtitling system, UC3MTitling..
Whether calculating routes, finding your vehicle, tracking products or simply knowing where you are at the moment, drivers and sailors currently use satellite navigation as a matter of course and rescue personnel and logistics providers have also already discovered the potential it affords them. Up to now, the applications have mainly been based on the direction signals of the military's publicly available Global Positioning Systems (GPS).
VERNON – Texas Agrilife Research fire and brush control studies in the Rolling Plains on a working ranch-scale showed the benefits and limitations of managed fires for reducing mesquite encroachment while sustaining livestock production.

Fast, low-energy memory for MP3s, smartphones and cameras could become a reality thanks to a development by scientists.
Researchers have created a tiny device that improves on existing forms of memory storage.
Conventional methods use electronic devices to convert data into signals that are stored as binary code. This latest device uses a tiny mechanical arm to translate the data into electrical signals. This allows for much faster operation and uses much less energy compared with conventional memory storage tools.
The addition of extremely small crystals to solid electrolyte material has the potential to considerably raise the efficiency of fuel cells. Researchers at TU Delft in the Netherlands were the first to document this accurately. Their second article on the subject in a very short time was published in the scientific journal, Advanced Functional Materials.

Said UC's Lentz, "The goal is to understand how the Maya lasted as a highly complex society for well over 1,500 years in a tropical environment. Their resource needs from forests were very great because they used trees to construct monumental buildings, for the creation of plaster (which was a surface cover for buildings and roadways), for cooking and many other needs. They had a sophisticated, long-lasting management system that apparently began to go awry during the Late Classic period." (AD 600-770)
Researchers at the University of California, San Diego School of Medicine claim that the availability of surgeons is a critical factor in public health and suggest that surgery should become an important part of the primary health care system.
ANAHEIM, March 27, 2011 — Your next new car hopefully won't be a lemon. But it could be a pineapple or a banana. That's because scientists in Brazil have developed a more effective way to use fibers from these and other plants in a new generation of automotive plastics that are stronger, lighter, and more eco-friendly than plastics now in use. They described the work, which could lead to stronger, lighter, and more sustainable materials for cars and other products, here today at the 241st National Meeting & Exposition of the American Chemical Society (ACS).
