Research Resilience: Disappointing Alzheimer’s trial yields new ideas

A new study in the New England Journal of Medicine documents the high-profile failure of a promising drug, bapineuzumab, to slow cognitive decline in dementia patients. Dr. Stephen Salloway, the study’s lead author, says researchers have learned key lessons that they are eager to apply in new attempts to find effective treatments for Alzheimer’s disease.

PROVIDENCE, R.I. [Brown University] — Dr. Stephen Salloway pulls no punches in describing the results of two clinical trials of the Alzheimer’s drug bapineuzumab that he helped to lead. The antibody failed to produce cognitive improvement for volunteers compared to a placebo, he and colleagues report Jan. 23 in the New England Journal of Medicine. (more…)

A new device developed at the University of Washington would let doctors use ultrasound to move kidney stones inside the body and help them pass by natural means. (more…)

Fluid Cathedrals: Gels Under the Microscope

ANN ARBOR— A dollop of hair gel might not look like much, but Michigan Engineering researchers have found that it’s a labyrinth of chambers and domes, constructed by the particles inside. These structures allow the gel to hold its shape and determine how much pressure it can withstand before it starts to flow.

While manufacturers currently use trial and error to develop gels with a particular degree of solidity, this discovery could provide a way to design gels for particular applications. (more…)

Dictators in The Dock

*Human rights trials for ex-dictators speed healing*

If dictators who torture, kill, or otherwise abuse their citizens’ human rights are overthrown, should they be brought to trial?

On one hand, convicting and punishing an ex-dictator and his minions would strike a welcome blow for justice in countries where it has been denied. (more…)
