Discover the Science of Health
Researchers from the University of California, Los Angeles (UCLA), Washington University in St. Louis and the Los Angeles Biomedical Research Institute have discovered that acne bacteria, which thrive in the oily pores of skin, consist of “bad” strains associated with pimples and “good” strains that may protect the skin and keep it healthy. The finding may help dermatologists develop new, strain-specific treatments for acne. The research is published in the Journal of Investigative Dermatology.
Statistics is powerful stuff. When using cross-sectional and longitudinal analyses to assess well-being in over 5,000 adults over thirty years, researchers initially found that well-being decreases with age: older people are unhappier than younger people. But when the researchers controlled for birth cohort, they found that each individual’s well-being increased with age. Sure, the 70 year olds were less happy than the 50 year olds; but those 70 year olds were happier than they were when they were 50. The study is published in the journal Psychological Science.
This week is Brain Awareness Week (BAW), an annual observance dedicated to raising public awareness about the progress and benefits of brain research. Coordinated by the Dana Alliance for Brain Initiatives and the European Dana Alliance for the Brain, every March, BAW unites the efforts of partner organizations around the world in a week-long celebration of the brain.
According to new research, learning becomes more difficult as we get older because our brains get too full for new information. This may be due, in part, to finding that with advanced age we get less sleep during the stage in which we don’t dream. Both studies are reported in the prestigious Nature family of journals.
Glaucoma is a group of eye conditions that can damage the optic nerve of the eye, which carries visual information from the eye to the brain. Glaucoma is the leading cause of preventable blindness in the United States. This potentially blinding eye disease currently affects 2.7 million people nationwide. Recent projections from the National Eye Institute (NEI) suggest this number of glaucoma cases will more than double by 2030 [1].
