Sad

Jolly SAD.

Examples of phasing macromolecular crystal structures based on single-wavelength anomalous dispersion (SAD) show that this approach is more powerful and may have more general application in structural biology than was anticipated. Better data-collection facilities and cryogenic techniques, coupled with powerful programs for data processing, phasing, density modification and automatic model buil...

Seasonal affective disorder (SAD)?

Every winter, especially when the days are short, I feel tired, depressed, and unproductive. Then the spring comes and I start feeling myself again. Is this just a normal seasonal cycle? I've heard about SAD, Seasonal Affective Disorder, but don't know much about it. Answer Dear Melancholy Baby, Somebody must've been feeling a bit clever when they christened the wintertime blues with the acrony...

Seasonal affective disorder (SAD)?

SAD effects on grantsmanship.

SAD is a state of depression induced by a lack of sufficient sunlight that occurs at high latitudes during the fall and winter. SAD causes people to be risk-adverse. Granting agencies of high latitude countries should time high-risk research competitions so they do not coincide with the SAD months.

Is it jolly SAD?

Examples of phasing macromolecular crystal structures based on single-wavelength anomalous dispersion (SAD) have demonstrated that this approach may have general applications in structural biology. With better data-collection facilities and cryogenic techniques, combined with powerful data-processing, phasing and density-modification programs, the SAD approach may prove simpler than phasing fro...
