UCLA assessment technique lets scientists see brain aging before symptoms appear

Tweet

UCLA scientists have used innovative brain-scan technology developed at UCLA, along with patient-specific information on Alzheimer's disease risk, to help diagnose brain aging, often before symptoms appear. Published in the January issue of Archives of General Psychiatry, their study may offer a more accurate method for tracking brain aging.

Abundance of ladybugs in olive orchards is an indicator of health and sustainability

Tweet

Present concern for the negative environmental impacts and growing demand for organic olive oil, arise the need to develop useful indicators of agroecosystem health in olive-growing regions. One key indicator of health and sustainability is the abundance and biodiversity of invertebrates, especially arthropod fauna. Spanish scientists have determined that Coccinellids (ladybugs) can be used to distinguish organic, conventional and integrated farming systems.

Study helps explain connection between sleep apnea, stroke and death

Tweet

BETHESDA, Md. (Jan. 6, 2009) − Obstructive sleep apnea decreases blood flow to the brain, elevates blood pressure within the brain and eventually harms the brain's ability to modulate these changes and prevent damage to itself, according to a new study published by The American Physiological Society. The findings may help explain why people with sleep apnea are more likely to suffer strokes and to die in their sleep.

Cassiopeia A Gets The 3-D Treatment

Tweet

Two new efforts have taken a famous supernova remnant from the static to the dynamic. A new movie of data from NASA's Chandra X-ray Observatory shows changes in time never seen before in this type of object. A separate team will also release a dramatic three-dimensional visualization of the same remnant.

Nearly ten years ago, Chandra's "First Light" image of Cassiopeia A (Cas A) revealed previously unseen structures and detail. Now, after eight years of observation, scientists have been able to construct a movie that tracks the remnant's expansion and changes over time.

New infant formula safety advice could prevent infant suffering

Tweet

Wheat-based infant follow-on formulas are better reconstituted with fruit juice and should be stored in the fridge at 4°C to prevent growth of meningitis bacteria, according to recent research.

The results of a study, published today in the Society for Applied Microbiology journal, Letters in Applied Microbiology, have shown that Cronobacter species do not grow in wheat-based infant formula stored at 4°C.

Physical activity may not be key to obesity epidemic

Tweet

MAYWOOD, Ill. -- A recent international study fails to support the common belief that the number of calories burned in physical activity is a key factor in rising rates of obesity.

Researchers from Loyola University Health System and other centers compared African American women in metropolitan Chicago with women in rural Nigeria. On average, the Chicago women weighed 184 pounds and the Nigerian women weighed 127 pounds.
