The role that Epstein-Barr virus (EBV) plays in the development of multiple sclerosis (MS) may be caused by a higher level of cross-reactivity, where the body’s immune system binds to the wrong target, than previously thought.

In a new study published in PLOS Pathogens, researchers looked at blood samples from people with MS, as well as healthy people infected with EBV and people recovering from glandular fever caused by recent EBV infection.

The study investigated how the immune system deals with EBV infection as part of worldwide efforts to understand how this common virus can lead to the development of multiple sclerosis, following 20 years of mounting evidence showing a link between the two.

Walmart showed off its use of augmented reality and artificial intelligence in its retail operations. It turns out that AR is leading to better digital sales and cool new applications that haven’t been done before.

The techniques include virtual try-on of outfits, virtual showroom experiences and digital twins, said Desirée Gosby, vice president of emerging technology at Walmart Global Tech, in an interview with VentureBeat.

She emphasized the importance of AR and related technologies for enhancing customer experiences and improve productivity.

What if we could find a way to make electric currents flow, without energy loss? A promising approach for this involves using materials known as topological insulators. They are known to exist in one (wire), two (sheet) and three (cube) dimensions; all with different possible applications in electronic devices.

Theoretical physicists at Utrecht University, together with experimentalists at Shanghai Jiao Tong University, have discovered that topological insulators may also exist at 1.58 dimensions, and that these could be used for energy-efficient information processing. Their study was published in Nature Physics.

Classical bits, the units of computer operation, are based on electric currents: electrons running means 1, no electrons running means 0. With a combination of 0’s and 1’s, one can build all the devices that you use in your daily life, from cellphones to computers. However, while running, these electrons meet defects and impurities in the material, and lose energy. This is what happens when your device gets warm: the energy is converted into heat, and so your battery is drained faster.

Number theorists have been trying to prove a conjecture about the distribution of prime numbers for more than 160 years.

The Riemann hypothesis is the most important open question in number theory—if not all of mathematics. It has occupied experts for more than 160 years. And the problem appeared both in mathematician David Hilbert’s groundbreaking speech from 1900 and among the “Millennium Problems” formulated a century later. The person who solves it will win a million-dollar prize.

OpenAI says GPT-4o can be used to teach you a language and a new demo video seems to prove them right.

Tesla Gigafactory Berlin has probably become the most fun factory among the company’s facilities worldwide. While Giga Berlin plays a huge part in ramping Tesla’s output globally, the electric vehicle maker also seems determined to ensure that the facility’s employees are well supported. This means that if employees need to destress, they would not need to go too far.

With this in mind, it appears that Giga Berlin has launched an in-house “rave cave” of sorts. The facility’s teaser was posted by Tesla’s official Tesla Manufacturing account, which, strangely enough, shared its post with a hamster emoji. Amidst scenes of employees entering the apparent “rave cave” from a futuristic narrow tunnel, images of a cyber-hamster mascot could also be seen.
