    Mica provides clue to how water transports minerals

    Original @ – latest science and technology news stories In order to understand various environmental processes and learn to better address the effects of pollution, scientists have been interested in tracking the movement of elements through the environment, particularly at interfaces between water and mine… [...]

    Laser-cooled ions contribute to better understanding of friction

    Original @ – latest science and technology news stories In physics, it is useful to know as precisely as possible how friction phenomena arise—and not only on the macroscopic scale, as in mechanical engineering, but also on the microscopic scale, in areas such as biology and nanotechnology. It is quite difficult to study friction at the atom scale where non-linear effects prevail. [...]

    Why Every Leader Needs to Be Obsessed With Technology

    Original @ Singularity Hub This article is part of a series exploring the skills leaders must learn to make the most of rapid change in an increasingly disruptive world. The first article in the series, “How the Most Successful Leaders Will Thrive in an Exponential World,” broadly outlines four critical leadership skills—futurist, technologist, innovator, and humanitarian—and how they work […] [...]

    Spiky ferrofluid thrusters can move satellites

    Original @ – latest science and technology news stories Brandon Jackson, a doctoral candidate in mechanical engineering at Michigan Technological University, has created a new computational model of an electrospray thruster using ionic liquid ferrofluid—a promising technology for propelling small satellites through space. Specifically, Jackson looks at simulating the electrospray startup dynamics; in other words, what gives the ferrofluid its characteristic spikes. [...]

    Using sensors and social networks to make slopes safer

    Original @ – latest science and technology news stories The peace and quiet that envelope a lone hiker on a leaf-riddled trail or a rock climber perched on the top of a cliff seem a world away from the noise of a social media feed. But Department of Mechanical Engineering (MechE) alumnus Jim Christian SM ’14 had an idea to tap into the superabundance of social-media data to benefit athletes and outdoor adventurers. He, along with MIT Sloan School of Management alumnus Brint Markle MBA ’14, created a device that could help determine avalanche risk. Their device has led to a network in which people can upload and share critical real-time information about the conditions—including avalanche risk—on a particular slope or mountain. [...]

    New study describes method to save lives in chemical attacks

    Original @ – latest science and technology news stories A new study by Kiran Bhaganagar, associate professor of mechanical engineering at The University of Texas at San Antonio, and her research group, Laboratory of Turbulence Sensing & Intelligence Systems, is taking a closer look at the damage caused by chemical attacks in Syria. The Syrian Civil War, ongoing since 2011, has seen hundreds of people killed through the use of chemical weapons. [...]
