The interplay between viscoelasticity and inertia in dilute polymer solutions at high deformation rates can result in inertio-elastic instabilities. We show how fluid elasticity has a nonmonotonic effect on jet stability depending on magnitude, creating two distinct regimes. The nonlinear evolution of these instabilities generates a state of elasto-inertial turbulence (EIT) with different spatiotemporal features than Newtonian turbulence. We use high-speed digital schlieren imaging and dynamic mode decomposition to quantify EIT and identify two modes of instability which can lead to a transition to turbulence at a lower Reynolds number with flow-aligned structures in the turbulent region.

ISS systems hit a water recovery milestone of 98% with the better processing of water contained in brine created when crewmates’ urine is distilled.

It’s a scene straight out of a horror movie — a submersible with five souls on board implodes, deep below the ocean’s surface, at the resting place of the infamous Titanic.

Many reporters are asking if there will be an attempt to bring up the bodies.

Mitochondria are the powerhouses of the cell. New research shows cancer cells can steal these energy generators from healthy cells to speed their growth.

For Star Trek fans and tech nerds, the holodeck concept is a form of geek grail. The idea is an entirely realistic simulated environment where just speaking the request (prompt) seemingly brings to life an immersive environment populated by role-playing AI-powered digital humans. As several Star Trek series envisioned, a multitude of scenes and narratives could be created, from New Orleans jazz clubs to private eye capers. Not only did this imagine an exciting future for technology, but it also delved into philosophical questions such as the humanity of digital beings.

Modern IT networks are complex combinations of firewalls, routers, switches, servers, workstations and other devices. What’s more, nearly all environments are now on-premise/cloud hybrids and are constantly under attack by threat actors. The intrepid souls that design, implement and manage these technical monstrosities are called network engineers, and I am one.

Although other passions have taken me from that world into another as a start-up founder, a constant stream of breathless predictions of a world without the need for humans in the age of AI prompted me to investigate, at least cursorily, whether ChatGPT could be used an effective tool to either assist or eventually replace those like me.

No matter the need, these tiny PCs are here to serve. I’ve used many small form factor PCs and most of what I’ve used pales in comparison to the Xulu XR1 Pro. This device is not only the smallest of the tiny PCs I’ve tried, but it’s also the most powerful.

The device itself measures a scant 3.5 × 3.5 inches and is only 2.5 inches tall, making it the smallest AMD Ryzen 7-powered PC ever built. Yes, it’s tiny. But it also offers six USB ports, one USB Type C port, two HDMI ports, and a headphone jack.

As far as price is concerned, the Xulu XR1 Pro will start at around $299 and max out at around $399. So not only does this tiny machine punch above its weight, but it’s also at a price point that makes it even more appealing. Having an AMD Ryzen 7 desktop machine at that price is a bargain…no matter the size.

Overlapping lattices and innovative techniques have unlocked the secrets of bosonic materials, opening doors to unprecedented possibilities in condensed matter physics.

Physicists at UC Santa Barbara have unlocked the secrets of an extraordinary material made of bosons. Traditionally, the scientific community has focused on understanding the behavior of fermions, the subatomic particles responsible for the stability and interaction of matter. However, this recent breakthrough explores the unique properties of bosons, shedding light on a less explored realm of particle physics.

By overlapping lattices of tungsten diselenide and tungsten disulfide in a twisted configuration known as a moiré… More.
