Yolo and LMK, two Snapchat apps that allow users to send anonymous messages, are no longer available to users of the social media platform after parent company Snap suspended them Tuesday.The suspension comes in response to a lawsuit filed Monday on behalf of Kristin Bride, the mother of an Oregon teen who took his own life in 2020 after receiving bullying messages via Yolo … [Read more...] about Snap suspends anonymous Q&A apps Yolo and LMK after lawsuit over teen’s death
Researchers develop artificial intelligence that can detect sarcasm in social media
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
Low temperature physics gives insight into turbulence
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
Column: That ‘infrastructure’ fee on some internet bills is just a stealth rate hike
Steve Kunzer recently received an email from his internet service provider, Frontier Communications, informing him that the company had made a mistake.It wasn’t charging him enough.“During a recent review, Frontier determined that you are not being charged the Frontier Internet Infrastructure Surcharge, which applied to your service at the expiration of your internet … [Read more...] about Column: That ‘infrastructure’ fee on some internet bills is just a stealth rate hike
Graphene key for novel hardware security
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
Smartphone breath alcohol testing devices vary widely in accuracy
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
This system helps robots better navigate emergency rooms
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
Universal equation for explosive phenomena: Mathematicians find core mechanism to calculate tipping points
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
A teen who was bullied on Snapchat died. His mom is suing to hold social media liable
One of the last things that Carson Bride did before taking his own life was look to his phone for help.The 16-year-old had been receiving anonymous messages on Snapchat for months, according to a federal lawsuit filed Monday in California, through a popular Snapchat app called YOLO. The messages included sexual comments and taunts over specific incidents, like the time he’d … [Read more...] about A teen who was bullied on Snapchat died.

Light emitters for quantum circuits
The promise of a quantum internet depends on the complexities of harnessing light to transmit quantum information over fiber optic networks. A potential step forward was reported today by researchers in Sweden who developed integrated chips that can generate light particles on demand and without the need for extreme refrigeration. Quantum computing today relies on states of … [Read more...] about Light emitters for quantum circuits
