Drug slows progression of moderate to severe Alzheimer's disease

Memantine, a new drug, has been found to slow the mental and physical deterioration of patients with moderate to severe Alzheimer's disease. The study, led by Dr. Barry Reisberg, showed that patients taking memantine experienced significantly less decline in cognition and daily life activities compared to those receiving a placebo.

Beyond 'pi in the sky'

The WMAP experiment's results confirm many aspects of inflationary theory while ruling out others. The latest trends in cosmology suggest a new era of precision cosmology, where speculation about the universe is confirmed or rejected by solid experimental data.

Internet rising as preferred traffic info source

A Penn State study found that younger generations rely on the internet for travel information, while older populations turn to radio and TV. Internet awareness is increasing, leading to a substitution effect where TV users shift to using the internet and radio, and telephone use also increases.

IBM to help CERN build massive data grid

CERN and IBM will collaborate on a massive data grid project to handle the extreme data challenges of the Large Hadron Collider. The project aims to create a one petabyte storage solution and integrate it with Grid computing systems, enabling scientists to access their data from anywhere in the world.

Study provides new insights into the functional neuroanatomy of motor imagery

A new study explores brain activity during explicit mental operations of finger representations using objective confirmation of performance. The researchers found that brain areas associated with motor execution and imagery were equally activated, suggesting a functional gradation from more 'executive' to more 'imaginative' areas.

Statins could reduce risk of cardiovascular disease

A new study found that statins can significantly reduce the risk of cardiovascular disease in people with high blood pressure and normal or low cholesterol levels. The treatment resulted in a 36% lower risk of primary events such as death from CHD and non-fatal heart attacks, primarily within the first year of treatment.

Peering inside a blood vessel

Dr. Alan Wilman is developing a new MRI technique that provides highly detailed images of blood vessels, allowing doctors to diagnose conditions like heart attacks and strokes earlier. His goal is to create a safer and cheaper alternative that can help prevent deaths by aiding in early diagnosis.

Broccoli could fight cancer

Researchers have found that heating broccoli to 60°C increases the levels of anti-carcinogenic sulphoraphanes, which may help prevent cancer. To achieve high levels of these beneficial compounds, plant breeders could consider eliminating genes that code for a protein called ESP.

VA increasing flu immunization rate

The study found that vaccinated elderly patients were 48% less likely to die during the 1998-99 season and 50% less likely to die during the 1999-2000 season. Additionally, vaccinated patients were less likely to develop pneumonia, cardiac disease, and stroke, confirming previous VA research on flu shots' life-saving benefits.
