Gully patterns document Martian climate cycles

Gullies carved into impact craters on Mars provide a window into climate change on the Red Planet. A new analysis suggests Mars has undergone several ice ages in the last several million years. The driver of these climate swings is likely the Red Planet's wobbly axis tilt.

Remembering Stan Aronson

Students, colleagues, patients — so many people have so many comments, so many anecdotes about Dr. Stanley Aronson, founding dean of the Alpert Medical School. A sampling:

When preparation is everything

For years, police officers from Brown’s Department of Public Safety have trained with Providence police on emergency scenarios and techniques. This year, for three days during the winter break, that special training — clearing buildings, negotiating stairwells, entering rooms, administering first aid until it’s safe for EMS crews — took place in Wilson Hall.

On the ups and downs of the seemingly idle brain

Even when it seems not to be doing much, the brain maintains a baseline of activity in the form of up and down states of bustle and quiet. To accomplish this seemingly simple cycle, it maintains a complex balance between the activity of many excitatory and inhibitory cells, Brown University scientists report in the Journal of Neuroscience.
Questions for Sohini Ramachandran

Probing the deep history of human genes and language

Brown University evolutionary biologist Sohini Ramachandran has joined with colleagues in publishing a sweeping analysis of genetic and linguistic patterns across the world’s populations. Among the findings is that geographic distance predicts differentiation in both language and genes.

South Africa

Grant funds effort to test, treat, and keep men in HIV care

In a country with especially high rates of HIV infection, many men in South Africa do not receive testing and treatment. Mark Lurie, assistant professor of epidemiology and medicine, will work with collaborators in Cape Town to test a new program to better retain men in care.

Researchers study marine ecological changes at Easter Island

Late last year, Jon Witman and Robert Lamb spent three weeks studying coral and other marine life in the waters around Easter Island, part of a research project led by Universidad Catolica de Santiago de Chile. Unlike most of the world, the coral around Easter Island appears to be increasing.
