Researchers at Chalmers University of Technology have shown that between 87 and 98 percent of ships comply with the tougher regulations for sulphur emissions that were introduced in northern Europe in 2015. The lowest levels of compliance were observed in the western part of the English Channel and in the middle of the Baltic Sea.
Researchers found marijuana shopping searches nearly tripled in the United States from 2005 to 2017, peaking between 1.4 and 2.4 million searches each month. Mail-order marijuana retailers occupied half of the first-page results, and three out of every four searches resulted in a mail-order marijuana retailer as the very first suggested link.
Researchers from Tokyo Metropolitan University used a light-sensitive iridium-palladium catalyst to make 'sequential' polymers, using visible light to change how different building blocks are combined into polymer chains. By simply switching the light on or off, they were able to realize different compositions along the polymer chain, allowing precision control over physical properties and material function. This may drastically simplify existing polymer production methods, and help overcome fundamental limits in creating new polymers.
A polymer mat developed at Rice University has the ability to fish biologically harmful contaminants from water through a strategy known as 'bait, hook and destroy.'
Online gift-giving is spreading in social networks and causing people to give more gifts -- online and in person -- according to a new study led by René Kizilcec, Cornell University assistant professor of information science. About half of these gifts were unlikely to have occurred offline or via another online channel.
Researchers with the Martinos Center for Biomedical Imaging at Massachusetts General Hospital have developed a new technique based on artificial intelligence and machine learning that should enable clinicians to acquire high-quality images from limited data.
A team of University of Missouri neuroscientists are inching closer to developing the tools needed to decipher the brain. Now, the team has published a new paper that demonstrates how these proteins can be used as tools to regulate the activity of individual neurons in the brain through changes in temperature. These tools will advance fundamental brain research and potentially lead to 'deep brain stimulation' treatments used for Alzheimer's and Parkinson's patients.
Now a Category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale, Tropical Cyclone Marcus continues to strengthen as it moves south and keeps off-shore from Western Australia. NASA's Terra satellite looked at Marcus in infrared light and saw a well-organized hurricane with a wide eye.
Radar satellite images show a large swath of Texas oil patch is heaving and sinking at alarming rates, according to a geophysical team from Southern Methodist University. Analysis of the images with oil activity data from the Texas Railroad Commission suggests decades of oil activity have destabilized localities of the 4,000-square-mile area, which is populated by small towns, roadways and a vast network of oil and gas pipelines and storage tanks.
In a study that holds promise for self-driving cars, MIT researchers have developed a system that can image and gauge the distance of objects shrouded by fog so thick that human vision can't penetrate it.
