Do you text while driving? You likely share a fundamental trait with others who do the same.
Researchers at Pennsylvania State University have identified a common behavioral characteristic among people who engage in the risky business of texting and driving: impulsiveness. Their study, published in the October issue of Accident Analysis & Prevention, looked at delayed discounting — or people’s devaluation of a delayed reward — among those who said they frequently text while driving, and those who said they do not.
Those who regularly partake in this tempting but dangerous activity had something in common: They were less interested in delayed rewards than their non-texting-while-driving counterparts. In other words, they tended to be more impulsive.
“The study supports the conclusions that texting while driving is fundamentally an impulsive choice made by drivers,” the authors wrote.
On Tuesday, Charlie Sheen appeared on Today to reveal that he is HIV-positive. The 50-year-old actor told host Matt Lauer he wasn’t sure when he contracted the virus, but that he was diagnosed roughly four years ago.
“It’s a hard three letters to absorb. It’s a turning point in one’s life,” Sheen said on Today. “I have a responsibility now to better myself and to help a lot of other people, and hopefully with what we’re doing today others will come forward and say, ‘Thanks, Charlie.'”
Though he’s perhaps the most high-profile individual to go public with his HIV status in recent years, Sheen is just one of an estimated 36.9 million people globally who were HIV-positive at the end of 2014. While the disease is still a major problem in many parts of the world — primarily Sub-Saharan Africa and parts of Asia — there have been…
Keeping intimacy alive in a long-distance relationship isn’t as hard as it used to be. Thanks to technology, geographically challenged partners can talk, text and videochat at all hours of the day and night. Options abound, even, for remotely controlling each other’s sex toys.
Though we can words and sound — and even vibrator controls — over great distances, few options exist for realistically replicating the sensation of human touch. Poised to change that is the Tesla Suit, a new virtual reality outfit that simulates the sensation of body contact.
Its founders claim to have transmitted history’s first virtual hug. “It’s a new dimension in communication,” co-founder Dimitree Marozau told Mic.
The chip-enabled credit card system long used in Europe, a watered down version of which is rolling out for the first time in America, is meant to create a double check against fraud. In a so-called “chip-and-PIN” system, a would-be thief has to both steal a victim’s chip-enabled card and be able to enter the victim’s PIN. But French forensics researchers have dissected a real-world case in which criminals outsmarted that system with a seamless chip-switching trick—and pulled off the feat with a slip of plastic that’s almost indistinguishable from a normal credit card.
French computer security researchers at the École Normale Supérieure university and the science and technology institute CEA late last week published a paper detailing a unique case of credit card fraud they analyzed as investigators in a criminal case. Five French citizens (whom the researchers didn’t name in either their paper…
Automotive parts manufacturer Faurecia is developing an Active Wellness seat to monitor emotions of drivers. The seat detects stress and fatigue via built in seat sensors, and then offers a customized treatment to the driver.
“If you’re stressed out, your heart rate increases and your respiration increases,” Faurecia’s Vice President of Innovation, Rob Huber, told CNBC’s Closing Bell. “If you press ‘stress detected,’ it’ll give you a soothing massage and a warming sensation that will calm you down.”

Researchers in Europe have developed a “tractor beam” made of sound waves, but don’t expect any Star Trek-style starship towing just yet. Asier Marzo, a Ph.D. student at the Public University of Navarre, worked with professors from the Universities of Sussex and Bristol to produce what they call an “acoustic hologram” that can hold small objects, move them around and rotate them, and — earning the technique its “tractor beam” moniker — pull them in.
It works by sending out ultrasound vibrations that interfere and harmonize with each other, affecting the air molecules and forming an invisible — but tangible — shape.
“It is the same as when you go to the doctor for an echography or when they destroy kidney stones with ultrasound,” wrote Marzo in an email to NBC News. “We are going to try to apply the same principle but for manipulating…
Scientific discovery is often the result of painstaking research and experimentation, with each step in the process mapped out and calculated to a T. Sometimes, it’s a complete accident.
Such was the case with the discovery of a tool to remove mercury from the planet’s water and soil. A team of researchers set out to create a new, cheap and widely available kind of plastic; instead, they ended up with a polymer that may revolutionize the way we get rid of the poison.
The materials used, sulphur and limonene, are extremely common — the former is a naturally occurring element and a primary by-product of gas and oil production, and the latter is found in citrus fruits. According to Justin Chalker, one of the study’s researchers, 70 million tons of sulphur and 70,000 tons of limonene are produced each year.
