Catalan scientists have shown that using mud from waste water treatment plants as a partial alternative fuel can enable cement factories to reduce their CO2 emissions and comply with the Kyoto Protocol, as well as posing no risk to human health and being profitable. These are the results of an environmental impact assessment.

MADISON — A fundamental question about how sugar units are strung together into long carbohydrate chains has also pinpointed a promising way to target new medicines against tuberculosis.

URBANA – When a dad changes diapers and makes pediatrician's appointments, he's more likely to stay interested and involved when his child makes the transition to school, said a new University of Illinois study that explores the role of parent involvement on student achievement.

Rapamycin, a drug given to transplant recipients to suppress their immune systems, has a paradoxical effect on cells responsible for immune memory, scientists at the Emory Vaccine Center have discovered.

In experiments conducted in both mice and monkeys, rapamycin can stimulate the formation of memory CD8 T cells, which enable the immune system to respond faster and stronger to an infectious agent upon a second encounter.

Patients with an Implantable Cardioverter Defibrillator (ICD) have an ongoing risk of sudden incapacitation that might cause harm to others while driving a car. Driving restrictions are imposed making these recommendations an important guideline for patients.

A consensus statement with recommendations for drivers with ICD's was presented at a press conference at the Europace 2009 meeting, in Berlin, Germany on Sunday 21 June.

University of Georgia researchers have developed a successful way to grow molecular wire brushes that conduct electrical charges, a first step in developing biological fuel cells that could power pacemakers, cochlear implants and prosthetic limbs. The journal Chemical Science calls the technique "a significant breakthrough for nanotechnology."

Washington, D.C. – The amount of time imaging equipment is in use in outpatient settings does not approach use rates President Obama and the Medicare Payment Advisory Commission (MedPAC) recommend Medicare utilize to calculate reimbursement for imaging, according to data recently collected by the Radiology Business Management Association (RBMA), a national association of business professionals in radiology.

MADISON, WI, JUNE 15, 2009 – Dissolved organic carbon (DOC) losses from tile drains are an underquantified portion of the terrestrial carbon cycle. This is particularly important in the eastern corn belt where tile drainage dominates the agricultural landscape. Specific land management practices, such as manure application, can play a large role in the export of DOC as soluble organic carbon is applied to or injected into the soil surface.

New Rochelle, NY, June 19, 2009—Scientists say they are forging ahead in developing replacements for petrochemical fuels that will be cost-competitive and renewable while having a minimal impact on the environment, reports Genetic Engineering & Biotechnology News (GEN).

Billing claims from health insurance companies can provide insights on the long-term health of kidney transplant patients, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN). The findings indicate that valuable health information can be obtained by analyzing medical insurers' reimbursement documents, a process that is much simpler and cheaper than many other forms of clinical investigation.

TORONTO, ON – New research by a team of University of Toronto scientists could lead to substantial advancements in the performance of a variety of electronic devices including digital cameras.

Researchers created a light sensor – like a pixel in a digital camera – that benefits from a phenomenon known as multi-exciton generation (MEG). Until now, no group had collected an electrical current from a device that takes advantage of MEG.

In Los Angeles County, being disabled can cost a year's income. That's because the annual cost of in-home care services for seniors living alone is now $319 more than this group's median income of $17,029.

Combine long-term care expenses with other basic expenses, such as food and rent, and a Los Angeles senior living alone will need twice the median income to survive, according to new data released today by the UCLA Center for Health Policy Research and the Insight Center for Community Economic Development.

DURHAM, N.C. – Bioengineers at Duke University have developed a laboratory robot that can successfully locate tiny pieces of metal within flesh and guide a needle to its exact location -– all without the need for human assistance.

The successful proof-of-feasibility experiments lead the researchers to believe that in the future, such a robot could not only help treat shrapnel injuries on the battlefield, but might also be used for such medical procedures as placing and removing radioactive "seeds" used in the treatment of prostate and other cancers.

Researchers at the Max Planck Institute for Chemical Ecology in Jena and their colleagues from the Czech Academy of Sciences in Prague have developed a new method to quickly and reliably detect metabolites, such as sugars, fatty acids, amino acids and other organic substances from plant or animal tissue samples. One drop of blood -- less than one micro liter -- is sufficient to identify certain blood related metabolites.
