Simulations clarify the mechanism of coupled plasma fluctuations

In nature, phenomena in which multiple fluctuations occur in a coupled manner are frequently observed. For example, in large earthquakes, cases of them occurring consecutively in adjacent regions have been reported. When ...

Reversing age-related fertility decline in male fruit flies: The crucial role of seminal fluid

As males age, their reproductive success typically declines. A study on fruit flies, led by University of Oxford researchers, has found that while old males do produce fewer offspring than young males, this is not because ...

Ship slime build-up: Biofilm growth model could enable lower costs and emissions in ocean transport

Slime build-up is a costly drag on fuel efficiency for ocean-going cargo ships, leading to more emissions and, eventually, higher consumer prices. A study published in the journal, npj Biofilms and Microbiomes, suggests a ...

Salt deposit ring inside your pasta pan? Researchers unveil the physical mechanisms at play

If you've ever tossed a generous pinch of salt into your pasta pan's water for flavor or as an attempt to make it boil faster, you've likely ended up with a whitish ring of deposits inside the pan.

Researchers propose a novel method to shed light on PFOS-induced neurotoxicity

The term "omics" refers to the study of the entirety of molecular mechanisms that happen inside an organism. With the advent of omics technologies like transcriptomics, proteomics, metabolomics, and lipidomics, our understanding ...

Newly discovered 'kiss and capture' mechanism explains the formation of Pluto and its largest moon

Billions of years ago, in the frigid outer reaches of our solar system, two icy worlds collided. Rather than destroying each other in a cosmic catastrophe, they spun together like a celestial snowman, finally separating while ...

Cooperation between two intruders moving side-by-side in granular media

In bird colonies, schools of fish and cycling pelotons, significant interactions occur between individuals through the surrounding fluid. These interactions are well understood in fluids such as air and water, but what happens ...

Scientists reinvent equations governing formation of snowflakes, raindrops and Saturn's rings

Skoltech researchers have proposed novel mathematical equations that describe the behavior of aggregating particles in fluids. This bears on natural and engineering processes as diverse as rain and snow formation, the emergence ...

Molecular 'pinball': Superfast collisions predict supercritical fluid properties

Neither gas nor liquid, supercritical fluids exhibit a unique mashup of the properties of both and arise when fluids are pushed to very high temperatures and pressures. Their properties make them ideal for a wide variety ...
