How Soap Molecules Move Over Water

Posted by in categories: information science, particle physics

Researchers can now predict exactly how soap molecules spread across a body of water, an everyday but surprisingly complex process.

When a tiny drop of soapy water falls onto a pool of liquid, its contents spread out over the pool’s surface. The dynamics of this spreading depend on the local concentration of soap—which varies in time and is difficult to predict—at each point across the entire pool’s surface. Now Thomas Bickel of the University of Bordeaux in Talence, France, and Francois Detcheverry of the University of Lyon, France, have derived an exact time-dependent solution for these distributions [1]. The solution reveals surprisingly rich behaviors in this everyday phenomenon.

The duo considered a surfactant-laden drop spreading over the surface of a deep pool of fluid. Researchers have previously shown that the equations governing the transport of the surfactant particles can be mapped to a partial differential equation known as the Burgers’ equation, which was initially developed to describe flows in turbulent fluids.

Elon Musk made a bold prediction during Tesla’s Q3 2022 earnings call stating that Tesla would grow to become an enormous company by the end of this decade.

Tesla CEO Elon Musk dazzled and entertained listeners during the call, which was full of jokes and ambitious goals. That’s when he made the bold statement that Tesla could surpass both Apple and Saudi Aramco’s market cap in the future.

Study: Cancer-causing gas leaking from CA stoves, pipes

Posted by in categories: biotech/medical, health

Gas stoves in California homes are leaking cancer-causing benzene, researchers found in a new study published on Thursday, though they say more research is needed to understand how many homes have leaks.

In the study, published in Environmental Science and Technology on Thursday, researchers also estimated that over 4 tons of benzene per year are being leaked into the atmosphere from outdoor pipes that deliver the gas to buildings around California — the equivalent to the benzene emissions from nearly 60,000 vehicles. And those emissions are unaccounted for by the state.

The researchers collected samples of gas from 159 homes in different regions of California and measured to see what types of gases were being emitted into homes when stoves were off. They found that all of the samples they tested had hazardous air pollutants, like benzene, toluene, ethylbenzene and xylene (BTEX), all of which can have adverse health effects in humans with chronic exposure or acute exposure in larger amounts.

U.S. factories emerge as a strong point in a weakening economy

Posted by in categories: economics, employment

Factories have added 467,000 jobs in the last 12 months, as production jumped to its highest level since 2008. But manufacturing remains a much smaller slice of the U.S. economy than it used to be.

Chip can transmit all of the internet’s traffic every second

Posted by in categories: computing, internet

A single computer chip has transmitted a record 1.84 petabits of data per second via a fibre-optic cable – enough bandwidth to download 230 million photographs in that time, and more traffic than travels through the entire internet’s backbone network per second.

Asbjørn Arvad Jørgensen at the Technical University of Denmark in Copenhagen and his colleagues have used a photonic chip – a technology that allows optical components to be built onto computer chips – to divide a stream of data into thousands of separate channels and transmit them all at once over 7.9 kilometres.

First, the team split the data stream into 37 sections, each of which was sent down a separate core of the fibre-optic cable. Next, each of these channels was split into 223 data chunks that existed in individual slices of the electromagnetic spectrum. This “frequency comb” of equidistant spikes of light across the spectrum allowed data to be transmitted in different colours at the same time without interfering with each other, massively increasing the capacity of each core.

NASA Just Unveiled an Epic 12-Year Timelapse of The Entire Sky

Posted by in category: space

NASA continues to outdo itself with the majestic images of space that it keeps releasing – but even by the agency’s high standards, a 12-year timelapse of the entirety of the night sky is an impressive achievement.

The imagery has been captured over those years by the NEOWISE (Near-Earth Object Wide Field Infrared Survey Explorer) space telescope, which was originally launched in 2009 under the previous name ‘WISE’ to study the Universe outside of our Solar System.
