Nvidia’s next generation Lovelace architecture may not differ all that much from Ampere

Posted by in category: computing

But with more of everything?


Every day brings us closer to the launch of next generation video cards. The RX 6,000 series and Nvidia RTX 30 series have been with us for well over a year, and we’re looking forward to what’s coming next. Well known leaker Greymon55 loves a good tease and his latest tweet indicates that the fundamental architecture of the upcoming Lovelace, or RTX 40 series GPUs isn’t all that different from those of current Ampere RTX 30 GPUs.

The Lovelace architecture doesn’t change much. February 5, 2022

“Boson Clouds” Could Explain Dark Matter

Posted by in categories: cosmology, particle physics, quantum physics

The nature of dark matter continues to perplex astronomers. As the search for dark matter particles continues to turn up nothing, it’s tempting to throw out the dark matter model altogether, but indirect evidence for the stuff continues to be strong. So what is it? One team has an idea, and they’ve published the results of their first search.

The conditions of dark matter mean that it can’t be regular matter. Regular matter (atoms, molecules, and the like) easily absorbs and emits light. Even if dark matter were clouds of molecules so cold they emitted almost no light, they would still be visible by the light they absorb. They would appear like dark nebula commonly seen near the galactic plane. But there aren’t nearly enough of them to account for the effects of dark matter we observe. We’ve also ruled out neutrinos. They don’t interact strongly with light, but neutrinos are a form of “hot” dark matter since neutrinos move at nearly the speed of light. We know that most dark matter must be sluggish, and therefore “cold.” So if dark matter is out there, it must be something else.

In this latest work, the authors argue that dark matter could be made of particles known as scalar bosons. All known matter can be placed in two large categories known as fermions and bosons. Which category a particle is in depends on a quantum property known as spin. Fermions such as electrons and quarks have fractional spin such as 1/2 or 3/2. Bosons such as photons have an integer spin such as 1 or 0. Any particle with a spin of 0 is a scalar boson.

The Large Hadron Collider is sucking in graphics cards at a rapidly increasing rate

Posted by in categories: computing, physics

It’s no secret that, while the humble GPU was originally conceived for the express purpose of chucking polygons around a screen in the most efficient way, it turns out the parallel processing prowess of modern graphics chips makes for an incredibly powerful tool in the scientific community. And an incredibly efficient one, too. Indeed A Large Ion Collider Experiment (ALICE) has been using GPUs in its calculations since 2010 and its work has now encouraged their increased use in various LHC experiments.

The potential bad news is that it does mean there’s yet another group desperate for the limited amount of GPU silicon coming out of the fabs of TSMC and Samsung. Though at least this lot will be using it for a loftier purpose than mining fake money coins.

Electrostatic engineering gets the lead out for faster batteries

Posted by in categories: energy, engineering, transportation

Conventional batteries are a lot like camels. They’re great for storage and transportation, but they’re not exactly speedy.

For technologies that require a fast discharge of energy, such as heart defibrillators, alternative materials are often used; foremost among them, antiferroelectrics.

There is only a handful of known antiferroelectric materials, and most of them contain lead, so they aren’t safe enough for everyday applications. Now, a Cornell-led collaboration has discovered a new approach for making a lead-free antiferroelectric that performs as well as its toxic relatives.

Inspired by insects, engineers create spiky materials that could pop bacteria

Posted by in categories: biotech/medical, chemistry

Researchers have created intricately patterned materials that mimic antimicrobial, adhesive and drag reducing properties found in natural surfaces.

The team from Imperial College London found inspiration in the wavy and spiky surfaces found in insects, including on cicada and dragonfly wings, which ward off .

They hope the new could be used to create self-disinfecting surfaces and offer an alternative to chemically functionalized surfaces and cleaners, which can promote the growth of antibiotic-resistant bacteria.
