When a fragrance wafted through the bedrooms of older adults for two hours every night for six months, memories skyrocketed. Participants in this study reaped a 226% increase in cognitive capacity compared to the control group. The researchers say the finding transforms the long-known tie between smell and memory into an easy, non-invasive technique for strengthening memory and potentially deterring dementia.

Results of a long-term, federally funded study of cognitively healthy adults -- most with a family history of Alzheimer's disease -- have added to evidence that low spinal fluid levels of a protein linked to learning and memory in mice may serve as an early predictor of mild cognitive impairment (MCI) years before symptoms appear.

Scientists appear to have discovered a way to produce a true structure of the rare but naturally-occurring anti-HIV compound Lancilactone C from start to finish. The domino-like reaction enables the total synthesis of lancilactones and related compounds. Its non-cytotoxicity in mammals could potentially make this triterpenoid an ideal candidate for treating AIDS.
