You’ve probably seen them, perhaps on long roadtrips: wind turbines with enormous, hypnotic rolling blades, harnessing the clean power of wind for conversion into electric energy. What you may not know is that for the explosion in the number of wind turbines in use as we embrace cleaner sources of energy, these wind farms are…
Crowd Counting Through Walls with WiFi
Researchers in UC Santa Barbara professor Yasamin Mostofi’s lab have given the first demonstration of crowd counting through walls using only everyday communication signals such as WiFi. The technique, which requires only a wireless transmitter and receiver outside the area of interest, could have a variety of applications, including smart energy management, retail business planning…
Killing it Softly
So you drop your smartphone flat on its back. What’s the worst that could happen? These days, maybe a dent. A smartphone’s metal body is made of a crystalline material with a highly ordered arrangement of atoms. Such materials have a clear order to disrupt — with potential weak points defined by “defects” in that…
X-Ray Eyes In The Sky: Drones And WiFi For 3-D Through-Wall Imaging
Researchers at UC Santa Barbara professor Yasamin Mostofi’s lab have given the first demonstration of three-dimensional imaging of objects through walls using ordinary wireless signal. The technique, which involves two drones working in tandem, could have a variety of applications, such as emergency search-and-rescue, archaeological discovery and structural monitoring. “Our proposed approach has enabled unmanned…

Anomalous Grooves on Martian Moon Phobos Explained by Impacts
Some of the mysterious grooves on the surface of Mars’ moon Phobos are the result of debris ejected by impacts eventually falling back onto the surface to form linear chains of craters, according to a new study. One set of grooves on Phobos are thought to be stress fractures resulting from the tidal pull of…
Sandcastle Worms Inspire New Type of Underwater Adhesive
An interdisciplinary group of researchers at UC Santa Barbara has taken strides in the development of an underwater adhesive that has the potential for a variety of biomedical and non-biological applications. Areas such as tissue repair, dental adhesives and other surface adhesion applications—which are often required under adverse conditions, such as salty sea water and…
New Catalyst Process Uses Light for Rapid Polymerization
A team of chemistry and materials science experts from University of California, Santa Barbara and The Dow Chemical Company has created a novel way to overcome one of the major hurdles preventing the widespread use of controlled radical polymerization. In a global polymer industry valued in the hundreds of billions of dollars, a technique called…
