Tanzeem Choudhury, associate professor of computing and information science, is developing such an application, supported by the newly created Intel Science and Technology Center (ITSC) for Pervasive Computing, a collaboration between Cornell and five other universities, managed by the University of Washington.
Intel’s goal is to develop technologies capable of continuously learning and adapting to consumers’ needs. Pervasive Computing ITSC projects include “smart houses” that monitor family activity and help out in the kitchen, as well as applications like Choudhury’s for mobile health and mental well-being. Intel is providing funding to support two graduate students for two years or more for Choudhury’s research.
“There has been some work on using phones to measure physical activity,” Choudhury said. “But sensing mental health is [somewhat] underexplored.” Previously she has used mobile sensors to map people’s social networks, a process she calls “reality mining.”
She proposes to use the phone’s microphone to monitor stress levels in speech, with privacy protection to make the actual words unintelligible. Knowing where and when stressful events occur can lead to advice on how to avoid them. The tricky part is crafting the advisory messages.
“You have to be really careful how you do the feedback, to make sure you’re not going to have an adverse effect,” she explained. “There are subtle ways of engaging a person with a problem.”
Choudhury is collaborating with Deborah Estrin, director of the Center for Embedded Networked Sensing at the University of California-Los Angeles and a leader of the Open mHealth project, which aims to use mobile devices to enhance mental health. They will draw on the advice of physicians and psychiatrists in designing their applications. She also will work with other researchers in the Pervasive Computing ITSC to extend her system’s monitoring into the smart house.
Before joining the Cornell faculty this fall Choudhury began her work on mobile health monitoring at Dartmouth, and she continues to collaborate with Dr. Ethan Berke at Dartmouth Medical School and Andrew Campbell, professor of computer science at Dartmouth.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
