Man-Made Climate Change
A new study published in this week's issue of Nature is the first to show that human activity is altering the circulation of the tropical atmosphere and ocean through global warming. view more (2006-05-04)
Envisat altimeter watches Pacific for cold tongue of La Niña
Satellite measurements of a steep difference in sea surface height between the western and eastern tropical Pacific support predictions that a La Niña event is in the offing. view more (2006-03-06)
New findings show persistent El Niño-like conditions during past global warming
During the most recent period in Earth's past with a climate warmer than today, the tropical Pacific was in a stable state of El Niño-like conditions, according to a new study by researchers at the University of California, Santa Cruz. view more (2005-06-24)
New imaging compound might 'see' Alzheimer's earlier
A new imaging molecule that can detect and map plaques and tangles in the brains of people with Alzheimer's disease could eventually lead to earlier diagnosis of the devastating disease, researchers at the University of California, Los Angeles report in the Dec. 21, 2006, issue of the New England... view more (2006-12-21)
Study finds mix of disease processes at work in brains of most people with dementia
Few older people die with brains untouched by a pathological process, however, an individual's likelihood of having clinical signs of dementia increases with the number of different disease processes present in the brain. view more (2007-06-14)
NASA'S live tropical sea surface temperature Web site gives climate, hurricane clues
Sea surface temperatures give scientists information about ocean currents, climate, climate change and how a hurricane may evolve. Now, NASA has a web page that provides frequent updates on changing ocean temperatures. view more (2006-10-13)
New climate research reveals growing risk of water shortages and flooding in California
If the world continues to burn greenhouse gases, California may have an increased risk of winter floods and summer water shortages, even within the same year. This scenario may be more severe in future El Niño years. view more (2006-02-08)
Did dust bust the 2006 hurricane season forecasts?
A recent NASA study suggests that tiny dust particles may have foiled forecasts that the 2006 hurricane season would be another active one. view more (2007-03-29)
Can an omega-3 fatty acid slow the progression of Alzheimer's disease?
Nutritionists have long endorsed fish as part of a heart-healthy diet, and now some studies suggest that omega-3 fatty acids found in the oil of certain fish may also benefit the brain by lowering the risk of Alzheimer's disease. view more (2007-05-11)
NASA research reveals climate warming reduces ocean food supply
In a NASA study, scientists have concluded that when Earth's climate warms, there is a reduction in the ocean's primary food supply. This poses a potential threat to fisheries and ecosystems. view more (2006-12-07)
Global warming is reducing ocean life, increasing atmospheric carbon dioxide, say scientists
Alarming new satellite data show that the warming of the world's oceans is reducing ocean life while contributing to increased global warming. view more (2006-12-07)
High-Trauma Fractures in Older Men and Women Linked to Osteoporosis
Researchers at the California Pacific Medical Center (CPMC) Research Institute are challenging a widely held belief that fractures resulting from major trauma, such as automobile accidents, are not related to osteoporosis, the common disease that makes bones weak and prone to fracture. view more (2007-11-29)
Researchers announce results of study on genetic variation in Parkinson's disease
Researchers at the National Institutes of Health (NIH) have completed one of the first large-scale studies of the role of common genetic variation in Parkinson's disease (PD). view more (2006-09-28)
Prominent researchers advocate creation of national climate service
It's time for the United States to have a national climate service - an interagency partnership led by the National Oceanic and Atmospheric Administration and charged with understanding climate dynamics, forecasts and impacts - say six members of the University of Washington's Climate Impacts... view more (2006-11-29)
New study links Western wildfires to Atlantic Ocean surface temperatures
Western U.S. wildfires are likely to increase in the coming decades, according to a new tree-ring study led by the University of Comahue in Argentina and involving the University of Colorado at Boulder that links episodic fire outbreaks in the past five centuries with periods of warming sea surface... view more (2006-12-27)
Brain Abnormality Found In Alzheimer's Disease Related to Gait Impairment in Older Persons
A new study from Rush University MedicalCenter helps explain why gait problems are often progressive in old age and related to risk of dementia and death. view more (2006-01-26)
A change in the wind
Climate model simulations for the 21st century indicate a robust increase in wind shear in the tropical Atlantic due to global warming, which may inhibit hurricane development and intensification. view more (2007-04-18)
Study demonstrates improved health, survival in aged overweight male mice on resveratrol
Overweight aged male mice whose high calorie (fat) diet was supplemented by resveratrol, a natural compound found in common foods like grapes, wines and nuts, had better health and survival than aged overweight mice who did not receive it. view more (2006-11-02)
Nursing Home Placement Associated with Accelerated Cognitive Decline in Alzheimer's Disease
People with Alzheimer's disease experience an acceleration in the rate of cognitive decline after being placed in a nursing home according to a new study by the Rush Alzheimer's Disease Center. view more (2007-06-01)
Early results from Alzheimer's neuroimaging studies could speed research
Alzheimer's disease researchers may be able to reduce the time and expense associated with clinical trials. view more (2007-06-13)
Sustained blood pressure treatment lowers dementia risk in elderly
Maintaining high blood pressure treatment may reduce the risk of dementia in old age, researchers reported in the rapid access issue of Stroke: Journal of the American Heart Association. view more (2006-04-07)
Scientists find new genetic clue to cause of Alzheimer's disease
Variations in a gene known as SORL1 may be a factor in the development of late onset Alzheimer's disease, an international team of researchers has discovered. The genetic clue, which could lead to a better understanding of one cause of Alzheimer's, is reported in Nature Genetics online, Jan. 14,... view more (2007-01-15)
IODP scientists acquire 'treasure trove' of climate records off Tahiti coast
An international team of scientists, supported by the Integrated Ocean Drilling Program, reunited at the University of Bremen to analyze a trove of coral fossil samples retrieved from Tahitian waters during October and November 2005. view more (2006-03-02)
Tai Chi boosts immunity to shingles virus in older adults, NIH-sponsored study reports
Tai Chi, a traditional Chinese form of exercise, may help older adults avoid getting shingles by increasing immunity to varicella-zoster virus (VZV) and boosting the immune response to varicella vaccine in older adults. view more (2007-04-09)
Loss of body mass linked to development of Alzheimer's disease
Loss of body mass over time appears to be strongly linked to older adults' risk of developing Alzheimer's disease (AD), and the greater the loss the greater the chance of a person developing the disease, new research has found. view more (2005-09-27)
