New Dopamine Brain Target Discovered; Potential Breakthrough For Schiz
A team of Canadian researchers, lead by Dr. Susan George and Dr. Brian O'Dowd at the Center for Addiction and Mental health, discovered a Gq/11-coupled signalling unit that triggers a calcium signal. This novel target is turned on by stimulating D1 and D2 dopamine receptors. This is the first time that a direct connection between dopamine and calcium signals has been reported. This data has significant implications for schizophrenia. Rants: Life Well-Lived and Lost
Readers respond to the tragic death of CNET editor James Kim and reflect on the Luddite's Renaissance man. Plus: Links to our most commented-upon blogs. Acrylamide Levels In Food Should Be Reduced Because Of Public Health C
A summary report released today by a Joint Expert Committee of the UN Food and Agriculture Organization (FAO) and the World Health Organization (WHO) warns that the unintentional contaminant acrylamide in certain foods may be of public health concern since it has been shown to cause cancer in animals. Doctors Able To Predict Potential Ovarian Failure After Radiation
Doctors in the United Kingdom have created a table to predict when a woman who has undergone radiation therapy as a part of cancer treatment regimen in her abdominal or pelvic area may become sterile, according to a new study published in the July 2005 issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of ASTRO, the American Society for Therapeutic Radiology and Oncology. Lost in Space? Lots of Junk
There are literally tons of man-made debris orbiting the Earth, from rocket parts to dead satellites to human waste dumped by space station crews. Then there's the stuff that spacewalking astronauts have simply lost out there. GAO: Aviation Security: Federal Air Marshal Service Could Benefit From
This November 2005 report from the Government Accountability Office (GAO) recommends practices for the management of the Federal Air Marshal Service (FAMS), which has "undergone a number of changes in recent years, including a 2003 transfer from the Transportation Security Administration (TSA) to the U.S. Immigration and Customs Enforcement (ICE), and a 2005 transfer from ICE back to TSA."Discusses training efforts, career opportunities, internal controls, and related topics.

Researchers at Johns Hopkins have discovered how our anti-infection machinery turns itself down and limits the sniffles, congestion and fevers that are a side effect of the campaign against invading viruses. The discovery seems to solve part of the mystery of why the misery of the common cold lasts only so long. New Dye Could Offer Early Test For Alzheimer's; MIT Technique Is Nonin
MIT scientists have developed a new dye that could offer noninvasive early diagnosis of Alzheimer's disease, a discovery that could aid in monitoring the progression of the disease and in studying the efficacy of new treatments to stop it. The new dye, called NIAD-4, was developed through a targeted design process based on a set of specific requirements, including the ability to enter the brain rapidly upon injection, bind to amyloid plaques, absorb and fluoresce radiation in the right spectral range, and provide sharp contrast between the plaques and the surrounding tissue. The First State of the Carbon Cycle Report (SOCCR): The North American

Topics include the carbon cycle; energy, industry, and waste management activities; and land and water systems. Also includes a historical overview and a glossary. From the U.S. Climate Change Science Program. Breakthrough In Eye Cancer Treatment
Scientists at St. Jude Children's Research Hospital have demonstrated in a mouse model a new, locally applied treatment for the eye cancer retinoblastoma that not only greatly reduces the size of the tumor, but does so without causing the side effects common with standard chemotherapy.
