Engineers describe how fluid suspensions exhibit different behaviors at different scales
Honey is already a thick liquid, but let it begin to crystalize and it can become downright clumpy. The sugar crystals in suspension seem to increase its viscosity. This phenomenon occurs throughout the natural and constructed world: From mudflows to.....»»
Engineers invent octopus-inspired technology that can deceive and signal
With a split-second muscle contraction, the greater blue-ringed octopus can change the size and color of the namesake patterns on its skin for purposes of deception, camouflage and signaling. Researchers at the University of California, Irvine have d.....»»
Calculating the number of oranges that can be plucked from a fruit stand before it collapses
A small team of physicists and mechanical engineers from Universidad de Antofagasta, Universidad Autónoma de Chile and Universidad de O'Higgins, all in Chile, has found a way to find the stability points of granularly arranged monolayers in a single.....»»
A method to straighten curved space-time
One of the greatest challenges of modern physics is to find a coherent method for describing phenomena, on the cosmic and microscale. For over a hundred years, to describe reality on a cosmic scale we have been using general relativity theory, which.....»»
Progress in the investigation of ultrafast electron dynamics using short light pulses
When electrons move within a molecule or semiconductor, this occurs on unimaginably short time scales. A Swedish-German team, including Dr. Jan Vogelsang from the University of Oldenburg, has now made significant progress towards a better understandi.....»»
LastPass prompting users to set a stronger master password after major security incident
LastPass faced a major attack in 2022 after hackers gained access to sensitive user data through an exploit found on the computer of one of the engineers working for the company. More than two years after this incident, LastPass has now announced new.....»»
