Study stops stress-based drug relapse in rats

All too often, stress turns addiction recovery into relapse, but years of basic brain research have provided scientists with insight that might allow them develop a medicine to help. A new study in the journal Neuron pinpoints the neural basis for stress-related relapse in rat models to an unprecedented degree. The advance could accelerate progress toward a medicine that prevents stress from undermining addiction recovery.

Scientists describe brain activity map

John Donoghue, the Henry Merritt Wriston Professor of Neuroscience at Brown, is one of 11 authors of a new paper in the journal Science outlining the vision for a “Brain Activity Map.” In their brief essay, the scientists call for a large-scale research effort that “could put neuroscientists in a position to understand how the brain produces perception, action, memories, thoughts, and consciousness and be a major step toward a complete understanding of brain function and dysfunction.” Gaining such insights into

A new technique to simulate climate change
Two views, two approaches to simulation:

Scientists are using ever more complex models running on ever more powerful computers to simulate the earth’s climate. But new research suggests that basic physics could offer a simpler and more meaningful way to model key elements of climate.

Lectures celebrate Ma Digital Scholarship Lab
Digital scholarship:

The Brown University Library will host a series of talks this spring to celebrate the opening of the Patrick Ma Digital Scholarship Lab at the John D. Rockefeller Jr. Library. Speakers will include Brown faculty and visiting scholars from across the academic disciplines who will discuss and use the Lab to demonstrate ways in which digital technologies have impact on their teaching and research and enable new forms of student learning and interaction. All talks are free and open to the public and will take place in the Digital Scholarship Lab, located on the first floor of the John D.

New technique could improve optical devices
The orientation of light emission:

A multi-university research team has used a new spectroscopic method to gain a key insight into how light is emitted from layered nanomaterials and other thin films. The technique, called energy-momentum spectroscopy, enables researchers to look at the light emerging from a thin film and determine whether it is coming from emitters oriented along the plane of the film or from emitters oriented perpendicular to the film. Knowing the orientations of emitters could help engineers make better use of thin-film materials in optical devices like LEDs or solar cells.
