Ice core 'dipstick' indicates West Antarctic ice has thinned less than believed
Rising sea levels 20,000 years ago, as the last ice age was beginning to wane, often are attributed in part to melting in West Antarctica. But in a new study led by University of Washington researchers, an ice core of 1,000 meters was used as a sort of dipstick to show that a key section of the West Antarctic Ice Sheet probably never contained as much ice as scientists originally thought...New research indicates a 'troubled' greenhouse is brewing
Climates like those of the movie "Monsoon Wedding" may extend more widely into Africa, North America and South America, according to a University of Oregon geologist's analysis of an ancient greenhouse event. "We know the gathering greenhouse will be warm, but this new information confirms that the contrast between the rainy season and the dry season will increase dramatically," says Greg...Cancer related gene p53 not regulated as indicated by previous tissue culture research
The cellular cascade of molecular signals that instructs cells with fatally damaged DNA to self-destruct pivots on the p53 tumor suppressor gene. If p53 is inactivated, as it is in over half of all human cancers, checks and balances on cell growth fail to operate, and body cells start to accumulate mutations, which ultimately may lead to cancer. Not surprisingly, the regulation of this vital safe...Pittsburgh researchers discover that certain chemicals in the blood may indicate brain injury
Researchers at Children's Hospital of Pittsburgh have found that increased levels of certain proteins in the blood or spinal fluid may signal brain injury in infants with vomiting, fussiness and several other common symptoms. Infants with shaken baby syndrome (SBS) ?the most common cause of severe traumatic brain injuries in young children ?are often misdiagnosed because doctors rarely re...Study indicates dramatic rise in antibiotic-resistant community-acquired staph infections
Staph infections resistant to antibiotics, previously only associated with hospitalization or prior contact with the healthcare system, are now widespread in the community and coming home. A new study from Emory University School of Medicine and Grady Memorial Hospital, featured in the March 7, 2006 Annals of Internal Medicine, reports on a dramatic rise in antibiotic resistant community-...Predictive medicine: Genes indicate diseases before symptoms do
Today, doctors still follow the same basic paradigm for healthcare, said William Clarke, executive...Children's snoring may indicate a serious problem
The American Academy of Pediatrics issued new recommendations telling pediatricians to screen all children for snoring because it could be a sign of a serious illness. Children who snore loudly may// suffer from obstructive sleep apnoea syndrome (OSAS). Left untreated, the disorder can lead to growth, heart and pulmonary problems. As part of a routine examination of patients older tha...Pregnancy complications indicate health problems
According to researchers, women who have had a complicated pregnancy could benefit from screening to prevent diabetes and heart disease later on. Researchers in Glasgow, Scotland, suggest that recent evidence justifies monitoring women who have had difficult pregnancies //- for they are at risk of health problems later on in life. For example, those who develop diabetes during pregnancy a...Oral memory indicates future Alzheimer's patients
A word recall test is able to differentiate those who will get Alzheimer's disease from healthy older people. Alzheimer's disease is chiefly a condition of older people - so we can expect an increase in the number of cases as the population ages.// Treatments are now available and they seem to work best if they start early. This means early diagnosis is a priority. Researchers at the...Change in walking might indicate Dementia
According to new research from Albert Einstein College of Medicine, they have observed that doctors have a new tool that may help them predict who will develop a form of dementia later in life.// The research from Albert Einstein College of Medicine finds the presence of an abnormal gait in elderly people without dementia predicts the risk of developing dementia. The form of dementia is...
