Vegetation key to accurate climate modeling
Linking vegetation models to climate models when approximating the Earth's past and future climates may make climate predictions more accurate and could provide a better picture of the effects of global warming on the Earth, according to Penn State researchers. (2001-05-28)

NPL stages unique on-line experiments
Does your computer's clock always run slow? How good are human beings at estimating? How much does gravity vary over the globe? With your help we are attempting to find answers to these questions as part of a huge on-line Web event to celebrate World Metrology Day 2001, Sunday 20th May. This is the first time NPL have attempted such a global experiment and we need you to help us make it a success, whether you have any scientific training or not. (2001-05-16)

Not all allergy tests are created equal, study suggests
The results of most commonly used blood tests for allergies can vary widely depending on which laboratory does the actual testing - and which laboratory procedure is used, a new study suggests. This means that many people who are tested for allergies using these tests may be misdiagnosed. (2001-04-25)

PET scans aid in diagnosis of non-small-cell lung cancer patients
Diagnosing non-small-cell lung cancer patients often requires multiple tests and invasive procedures. An Australian research team reports that PET scanning is much more accurate in determining how far lung cancer has spread and should be used more rountinely. (2000-12-27)

New satellite-generated rain maps provide improved look at tropical rainfall
First-of-a-kind rain maps from NASA's Tropical Rainfall Measuring Mission may provide clues to developing El Niños and La Niñas and a better understanding of how latent heat from tropical rains influences weather around the world. The new maps will be discussed on Dec. 18 at a press briefing in San Francisco. (2000-12-17)

Rubber bullets miss more than they hit
Non-lethal guns have to be accurate otherwise they risk killing people rather than leaving them merely incapacitated. But, in the first study of its kind, US researchers have found that more than half of all non-lethal weapons are wildly inaccurate. (2000-12-12)

GMC revalidation proposals are inappropriate
The General Medical Council's proposal for a five-year assessment to identify potentially inadequate doctors would be unfair, inaccurate and very expensive, according to a letter in this week's BMJ. (2000-11-09)

New prostate cancer prognostic tool can help patients make treatment decisions
A new prognostic tool, developed at Memorial Sloan-Kettering Cancer Center, could aid physicians and patients in decision making regarding treatment options for early stage prostate cancer, and in identifying those patients who are at high risk of recurrence following radiation therapy. (2000-09-28)

On track
Using signals from GPS satellites, an ONR-funded researcher has developed a much more precise method of locating intercontinental-range ballistic missiles and other exo- atmospheric (space) targets. (2000-09-07)

Sentinel node biopsy identifies patients in which cancer of the vulva has spread
A new diagnostic tool used in patients with melanoma or breast cancer is also beneficial for women with vulva cancer. (2000-07-27)

Racial differences in body composition require modified skinfold-thickness
The prevalence of overweight among African American women (almost 50%) is significantly higher than in white women (about 33%). (2000-07-22)

Accuracy of adult memories of childhood is no greater than chance
It is often said that adolescence is the period in life that is most difficult to see clearly. Results of a new study from Northwestern University Medical School seem to support this adage. Northwestern researchers found that the likelihood of an adult acurately remembering events from childhood is no greater than choice. (2000-05-31)

Ultrasound technology may help glaucoma patients, study suggests
Ultrasound technology may soon play an important role in the treatment of glaucoma, an eye disease that can lead to blindness. New research suggests that examining an eye with ultrasound while exciting it with audible sound waves will give an accurate reading of the fluid pressure behind the cornea. (2000-05-30)

Leap day lecture explores the history and math behind the Gregorian Calendar
Math professor will explain the history of the calendar, including why there were only 19 days in Sept. 1752 in Great Britain but 30 in Spain. He will also use continued fractions to illustrate the accuracy of the calendar and to give examples of how it could be made more accurate. (2000-02-24)

Optimistic prognoses for terminally ill patients may be detrimental to their care
Many doctors inaccurately predict prognoses for terminally ill patients and most overestimate how long patients will survive, find researchers from Chicago in this week's BMJ. (2000-02-17)

New treadmill 'scores' may help physicians better diagnose heart disease
A new scoring system used in treadmill testing may help physicians improve their accuracy in diagnosing heart disease, according to a study presented today at the American Heart Association Scientific Sessions. (1999-11-08)

Age-related declines in mental function
When young adults are asked to remember a list of words, then switch tasks and do a math problem, they use areas in the front of the brain and towards the back of both hemispheres-- -the visual cortices. But when older adults perform the same tasks, they are more likely to use an area on the left front side of the brain---the dorsolateral prefrontal cortex (DLPFC). (1999-10-25)
