X-ray lasers: Why does brighter mean darker?
When we illuminate something, we usually expect that the brighter the source we use, the brighter the resulting image will be. This rule also works for ultra-short pulses of laser light—but only up to a certain intensity. The answer to the question.....»»

A physics milestone: Miniature particle accelerator works
Particle accelerators are crucial tools in a wide variety of areas in industry, research and the medical sector. The space these machines require ranges from a few square meters to large research centers. Using lasers to accelerate electrons within a.....»»
Ancient diamonds shine light on the evolution of Earth
The analysis of ancient, superdeep diamonds dug up from mines in Brazil and Western Africa, has exposed new processes of how continents evolved and moved during the early evolution of complex life on Earth......»»
Study examines role of working memory, cognitive functions in English learners learning to write
When a person attempts to express their thoughts in writing, they use a series of cognitive functions like working memory to access words and ideas they want to convey, phonological awareness of concepts such as syntax and more. And that is in their.....»»
Saturday Citations: Gravitational waves, time travel and the simulated universe hypothesis
This week, researchers proved empirically that life isn't fair. Also, you'll notice that, in a superhuman display of restraint, I managed to write a paragraph about the simulated universe hypothesis without once referencing "The Matrix." (Except for.....»»

Feature request: iPhone jiggle mode is still criminally bad UI which desperately needs a fix
You know something’s bad when you’re about to write a feature request and then realise you already did do, more than a year go. Some 18 months after I asked Apple to fix the awful iPhone jiggle mode, nothing has changed, so consider this my renew.....»»
Researchers see a future for agricultural solar parks, but also challenges
Solar parks and agriculture do not have to be placed on separate fields. It is possible to combine both functions on the same field, researchers from Wageningen University & Research and Renergize Consultancy write in their position paper "Producing.....»»
Using air to deflect lasers
Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original quality of the beam, reports an interdisciplinary.....»»
