A maternal link to Alzheimer's disease
People who have a mother with Alzheimer's disease appear to be at higher risk for getting the disease than those individuals whose fathers are afflicted, according to a new study by NYU School of Medicine researchers. view more (2007-11-07)
Do 'light' cigarettes deliver less nicotine to the brain than regular cigarettes?
For decades now, cigarette makers have marketed so-called light cigarettes - which contain less nicotine than regular smokes - with the implication that they are less harmful to smokers' health. A new UCLA study shows, however, that they deliver nearly as much nicotine to the brain. view more (2008-09-29)
Brain regions do not communicate efficiently in adults with autism
A novel look at the brains of adults with autism has provided new evidence that various brain regions of people with the developmental disorder may not communicate with each other as efficiently as they do in other people. view more (2006-10-16)
UCLA study finds that simple lifestyle changes may improve cognitive function and brain efficiency
A UCLA research study published in the June issue of the American Journal of Geriatric Psychiatry found that people may be able to improve their cognitive function and brain efficiency by making simple lifestyle changes such as incorporating memory exercises, healthy eating, physical fitness and stress reduction into their daily lives. view more (2006-05-23)
New way to diagnose Alzheimer's disease promises earlier treatment
Physicians may be able to detect and treat Alzheimer's Disease (AD) in its earliest stages, when patients are experiencing only mild degrees of cognitive impairment, thanks to new diagnostic criteria proposed by an international group of researchers. view more (2007-09-17)
Radioactive 'understudy' may aid medical imaging, drug development
Broadway stars have understudies. Now, an increasingly popular radioactive isotope has its own stand-in. Developed in part by researchers at the National Institute of Standards and Technology (NIST), the substance might ultimately improve medical imaging, speed up clinical trials of many drugs and facilitate efforts to develop more individualized... view more...

Mechanisms of cardiovascular disease and cancer give clues to new therapies
Cardiovascular conditions leading to heart attacks and strokes are treated quite separately from common cancers of the prostate, breast or lung, but now turn out to involve some of the same critical mechanisms at the molecular level. view more (2008-11-24)
Advance towards early Alzheimer's diagnosis
An Australian research project has found a way to bring forward the detection of early stage Alzheimer's disease by up to 18 months. view more (2008-06-18)
A&T professor has technology to monitor bridge safety
North Carolina A&T State University has developed a technology that could have possibly prevented the bridge collapse in Minneapolis, Minnesota. view more (2007-08-06)
Power plants are major influence in regional mercury emissions
The amount of mercury emitted into the atmosphere in the Northeast fluctuates annually depending on activity in the electric power industry, according to researchers at the Yale School of Forestry & Environmental Studies. view more (2006-07-24)
Blood-flow metabolism mismatch predicts pancreatic tumor aggressiveness
Researchers from Turku, Finland, have identified a blood-flow glucose consumption mismatch that predicted pancreatic tumor aggressiveness, according to results of a study published in Clinical Cancer Research, a journal of the American Association for Cancer Research. view more (2009-08-26)
Molecular imaging sheds new light on progression of Alzheimer's disease
In the past, physicians were able only to follow the progression of Alzheimer's disease (AD) through careful clinical histories, noting the often subtle changes associated with cognitive decline over a number of years. view more (2008-06-17)
A picture of progress: PET imaging and biomarkers explored at ACS meeting
Doctors often have wished they could dispense with diagnostic guesswork and simply peer inside a human body to see the effects of a disease or if a particular medicine really works. view more (2005-09-01)
Low-dose estrogen shown safe and effective for metastatic breast cancer
When estrogen-lowering drugs no longer control metastatic breast cancer, the opposite strategy might work. Raising estrogen levels benefited 30 percent of women whose metastatic breast cancer no longer responded to standard anti-estrogen treatment. view more (2009-08-19)
No matter their size black holes 'feed' in the same way
Research by UK astronomers, published today in Nature (7th December 2006) reveals that the processes at work in black holes of all sizes are the same and that supermassive black holes are simply scaled up versions of small Galactic black holes. view more (2006-12-07)
Fluorescent glass SRMs are new tool for spectroscopy
Researchers at the National Institute of Standards and Technology (NIST) have developed two new calibration tools to help correct and validate the performance of analytic instruments that identify substances based on fluorescence. view more (2007-06-11)
Bright tumors, dim prospects
It doesn't matter how small or large it is, if a cervical tumor glows brightly in a PET scan, it's apt to be more dangerous than dimmer tumors. That's the conclusion of a new study of cervical cancer patients at Washington University School of Medicine in St. Louis. view more (2007-09-14)
UN body asks Lund Researchers to investigate new type of carbon sink
Trade in emission rights is intended to reduce global emissions of greenhouse gases. Countries with natural carbon sinks—areas that absorb more carbon dioxide than they give off—can ‘trade off’ that resource in return for their commitments to reduce emissions. Thus far this has largely involved forests. But now a new and... view more... (2001-11-09)
Food restriction increases dopamine receptor levels in obese rats
A brain-imaging study of genetically obese rats conducted at the U.S. Department of Energy's Brookhaven National Laboratory provides more evidence that dopamine - a brain chemical associated with reward, pleasure, movement, and motivation - plays a role in obesity. view more (2007-10-25)
Small molecule offers big hope against cancer
DCA is an odourless, colourless, inexpensive, relatively non-toxic, small molecule. And researchers at the University of Alberta believe it may soon be used as an effective treatment for many forms of cancer. view more (2007-01-17)
