Instruments in smart phones such as the accelerometer, gyroscope and proximity sensors represent a potential security vulnerability, according to researchers from Nanyang Technological University, Singapore (NTU Singapore), whose research was published in the open-access Cryptology ePrint Archive on 6 Dec.
For the past 10 years, the Camera Culture group at MIT’s Media Lab has been developing innovative imaging systems — from a camera that can see around corners to one that can read text in closed books — by using “time of flight,” an approach that gauges distance by measuring the time it takes light projected into a scene to bounce back to a sensor.
Bottlenose dolphins in Panama’s Bocas Del Toro Archipelago should be designated as endangered say the authors of a new study. Biologists working at the Smithsonian Tropical Research Institute discovered that the roughly 80 dolphins in the archipelago do not interbreed with other Caribbean bottlenose dolphins. Their low numbers jeopardize their long-term survival, which is threatened by increasing local boat traffic that killed at least seven dolphins in 2012.
A vast new study of changes in global wildlife over almost three decades has found that low levels of effective national governance are the strongest predictor of declining species numbers — more so than economic growth, climate change or even surges in human population.
According to a new study by the University of Basel, the European Commission — Joint Research Centre and the Centre for Ecology & Hydrology (CEH, UK), almost 36 billion tons of soil is lost every year due to water, and deforestation and other changes in land use make the problem worse. The study also offers ideas on how agriculture can change to become a part of the solution from being part of the problem
Researchers from the Digital Geography at the University of Helsinki have been studying whether social media data could be used to understand visitor’s activities in national parks and most recent results are presented in Scientific reports: Instagram, Flickr, or Twitter: Assessing the usability of social media data for visitor monitoring in protected areas.
Public health messaging about the safety of e-cigarettes needs to account for the worldviews of the target audience, with different groups displaying varying levels of trust depending on the source of the message, according to a recent study by the School of Public Health at Georgia State University.
With the power-conversion efficiency of silicon solar cells plateauing around 25%, perovskites are now ideally placed to become the market’s next generation of photovoltaics. In particular, organic-inorganic lead halide perovskites offer manufacturing versatility that can potentially translate into much higher efficiency: studies have already shown photovoltaic performances above 20% across different solar cell architectures built with simple and low-cost processes.
Significant increases in the death rates of white, middle-aged people over the last 15 years appear to be tied to increases in Republican voting that helped lead to Donald Trump’s election in 2016, according to a new study led by a Drexel University researcher.
As the West tallies the damages from the 2017 wildfire season, researchers at Oregon State University are trying to learn more about how embers form and about the blaze-starting potential they carry.
