Cruise operator Carnival reveals another data breach
Carnival Corporation, the largest cruise ship operator in the world, has disclosed details about a cybersecurity incident involving unauthorized access of its records. In a data breach letter sent to affected customers shared by Bleeping Computer, the company acknowledged the incident occurred earlier this year in March and allowed the unauthorized users to access the personal information relating to some of their guests, employees, and…
How far are we from a passwordless future?
This year, World Password Day served as a familiar reminder that businesses everywhere should examine the strength of their authentication practices. Passwords at log-in are no longer the only option for protecting access to systems, applications and devices – in fact, they haven’t been for some time. Despite inherent weaknesses, passwords endure because they can be used anywhere, on any device, at any time. Making…
Probing the dynamics of photoemission
Physicists at Ludwig-Maximilian University in Munich (LMU) and the Max Planck Institute for Quantum Optics (MPQ) have used ultrashort laser pulses to probe the dynamics of photoelectron emission in tungsten crystals. Almost a century ago, Albert Einstein received the Nobel Prize for Physics for his explanation of the photoelectric effect. Published in 1905, Einstein's theory incorporated the idea that light is made up of particles…
Physicists bring human-scale object to near standstill, reaching a quantum state
To the human eye, most stationary objects appear to be just that -- still, and completely at rest. Yet if we were handed a quantum lens, allowing us to see objects at the scale of individual atoms, what was an apple sitting idly on our desk would appear as a teeming collection of vibrating particles, very much in motion. In the last few decades, physicists…
Novel chirped pulses defy ‘conventional wisdom’
The 2018 Nobel Prize in Physics was shared by researchers who pioneered a technique to create ultrashort, yet extremely high-energy laser pulses at the University of Rochester. Now researchers at the University's Institute of Optics have produced those same high-powered pulses -- known as chirped pulses -- in a way that works even with relatively low-quality, inexpensive equipment. The new work could pave the way…

Cigarillo packaging can influence product perception, study finds
CHAPEL HILL - Text and pictorial warnings about the health effects of little cigars and cigarillos didn't fully curtail the appeal of bright colors and descriptions of flavors on packaging, a study by University of North Carolina Lineberger Comprehensive Cancer Center researchers found. In the absence of federal regulations for flavors on cigarillos and little cigars in the United States, UNC Lineberger researchers wanted to…
