People are more persuaded by the actual messages contained in social media posts than they are by how many others viewed the posts, a new study suggests. Researchers found that when people watched YouTube videos either for or against e-cigarette use, their level of persuasion wasn't directly affected by whether the video said it was viewed by more than a million people versus … [Read more...] about People are persuaded by social media messages, not view numbers: Study asked users to evaluate YouTube videos about e-cigarettes

As the use of artificial intelligence (AI) in health applications grows, health providers are looking for ways to improve patients' experience with their machine doctors. Researchers from Penn State and University of California, Santa Barbara (UCSB) found that people may be less likely to take health advice from an AI doctor when the robot knows their name and medical history. … [Read more...] about Patients may not take advice from AI doctors who know their names

Computer science researchers at the University of Central Florida have developed a sarcasm detector. Social media has become a dominant form of communication for individuals, and for companies looking to market and sell their products and services. Properly understanding and responding to customer feedback on Twitter, Facebook and other social media platforms is critical for … [Read more...] about Researchers develop artificial intelligence that can detect sarcasm in social media

A novel technique for studying vortices in quantum fluids has been developed by Lancaster physicists. Andrew Guthrie, Sergey Kafanov, Theo Noble, Yuri Pashkin, George Pickett and Viktor Tsepelin, in collaboration with scientists from Moscow State University, used tiny mechanical resonators to detect individual quantum vortices in superfluid helium. Their work is published in … [Read more...] about Low temperature physics gives insight into turbulence

As more private data is stored and shared digitally, researchers are exploring new ways to protect data against attacks from bad actors. Current silicon technology exploits microscopic differences between computing components to create secure keys, but artificial intelligence (AI) techniques can be used to predict these keys and gain access to data. Now, Penn State researchers … [Read more...] about Graphene key for novel hardware security

Alcohol-impaired driving kills 29 people a day and costs $121 billion a year in the U.S. After years of progress in reducing alcohol-impaired driving fatalities, efforts began to stall in 2009, and fatalities started increasing again in 2015. With several studies demonstrating that drinkers cannot accurately estimate their own blood alcohol concentration (BAC), handheld alcohol … [Read more...] about Smartphone breath alcohol testing devices vary widely in accuracy

Computer scientists at the University of California San Diego have developed a more accurate navigation system that will allow robots to better negotiate busy clinical environments in general and emergency departments more specifically. The researchers have also developed a dataset of open source videos to help train robotic navigation systems in the future. The team, led by … [Read more...] about This system helps robots better navigate emergency rooms

Climate change, a pandemic or the coordinated activity of neurons in the brain: In all of these examples, a transition takes place at a certain point from the base state to a new state. Researchers at the Technical University of Munich (TUM) have discovered a universal mathematical structure at these so-called tipping points. It creates the basis for a better understanding of … [Read more...] about Universal equation for explosive phenomena: Mathematicians find core mechanism to calculate tipping points
