Nvidia adds $79 billion in market value after CEO Jensen Huang says ChatGPT represents an inflection point for artificial intelligence

Posted by in categories: robotics/AI, security, supercomputing

But the computing power necessary for a company to adopt in-house AI capabilities is enormous, and that’s where Nvidia’s new service offering comes in. Dubbed “DGX Cloud,” Nvidia is offering an AI supercomputer accessible to its customers via a web browser. The company partnered with various cloud providers, including Microsoft, Google, and Oracle, to launch the service.

“Nvidia AI as a service offers enterprises easy access to the world’s most advanced AI platform, while remaining close to the storage, networking, security and cloud services offered by the world’s most advanced clouds,” Huang explained.

“Nvidia AI is essentially the operating system of AI systems today,” Huang also said.

Samsung unveils its own solution for satellite-based smartphone communication

Posted by in categories: computing, mobile phones, satellites

Earlier today, Samsung announced its own solution for satellite communication on smartphones. The company unveiled the 5G non-terrestrial networks (NTN) modem so phones can communicate with satellites in locations where there is no cellular network connectivity.

The company said that it aims to integrate this tech into its own Exynos chip, which is used in a lot of Samsung smartphones — but not the current flagship device, the Samsung Galaxy S23. The Korean tech giant describes this tech as using “satellites and other non-terrestrial vehicles” to provide connectivity in remote areas.

The move follows Apple, which launched satellite connectivity with iPhone 14 and 14 Pro for off-grid connectivity. The company first made this tech available in the U.S. and Canada, later expanding it to France, Germany, Ireland and the U.K. Apple relies on Globalstar’s satellite network.

Electrons’ magnetism confirms particle physics’ most precise prediction

Posted by in category: particle physics

No one has ever probed a particle more stringently than this.

In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise measurement of any property of an elementary particle, ever. Known as the electron magnetic moment, it’s a measure of the strength of the magnetic field carried by the particle.

That property is predicted by the standard model of particle physics, the theory that describes particles and forces on a subatomic level. In fact, it’s the most precise prediction made by that theory.

How does ChatGPT differ from human intelligence?

Posted by in category: futurism

Predictive-learning models have been around for decades, but what is new about ChatGPT is the way it is trained, giving it access to larger sets of data.

World witnesses Moon, Jupiter and Venus in perfect trifecta across skies

Posted by in category: space

The Moon, Jupiter and Venus appeared in a perfect trifecta in skies across the countries in what can be called a rare celestial synchronised dance. Jupiter and Venus and the moon created a triangle-like shape in the sky during nighttime as the celestial bodies came closer to each other.

The mysterious twin of Earth, Venus, and the solar system’s biggest planet, Jupiter, has been getting closer to each other as they move for conjunction on March 1. The planets, Jupiter and Venus, were joined by the moon early in the evening on Wednesday.

Short electrical pulses switch superconductivity on and off in magic-angle graphene

Posted by in categories: materials, particle physics

Superconductivity can be switched on and off in “magic-angle” graphene using a short electrical pulse, according to new work by researchers at Massachusetts Institute of Technology (MIT). Until now, such switching could only be achieved by sweeping a continuous electric field across the material. The new finding could help in the development of novel superconducting electronics such as memory elements for use in two-dimensional (2D) materials-based circuits.

Graphene is a 2D crystal of carbon atoms arranged in a honeycomb pattern. Even on its own, this so-called “wonder material” boasts many exceptional properties, including high electrical conductivity as charge carriers (electrons and holes) zoom through the carbon lattice at very high speeds.

In 2018, researchers led by Pablo Jarillo-Herrero of MIT found that when two such sheets are placed on top of each other with a small angle misalignment, things become even more fascinating. In this twisted bilayer configuration, the sheets form a structure known as a moiré superlattice, and when the twist angle between them reaches the (theoretically predicted) “magic angle” of 1.08°, the material begins to show properties such as superconductivity at low temperatures – that is, it conducts electricity without any resistance.

James Webb discovered massive galaxies that astronomers say shouldn’t exist

Posted by in category: cosmology

The James Webb Space Telescope has made a shocking discovery. According to a new paper published in the journal Nature, astronomers have discovered enormous distant galaxies that some say shouldn’t exist. These enormous galaxies are believed to be some of the early galaxies that formed after the Big Bang, and their discovery by Webb has left many scratching their heads in confusion.

Feasibility of mapping the human brain with expansion x-ray microscopy

Posted by in categories: bioengineering, biological, biotech/medical, mapping, nanotechnology, neuroscience

Hey folks, I’m excited to share a new essay with y’all on my proposed route towards nanoscale human brain connectomics. I suggest that synchrotron ‘expansion x-ray microscopy’ has the potential to enable anatomical imaging of the entire human brain with sub-100 nm voxel size and high contrast in around 1 year for a price of roughly $10M. I plan to continue improving this essay over time as I acquire more detailed information and perform more calculations.

For a brief history of this concept: I started exploring this idea during undergrad (working with a laboratory-scale x-ray microscope), but was cut short by the pandemic. Now, I’m working on a PhD in biomedical engineering centered on gene therapy and synthetic biology, but I have retained a strong interest in connectomics. I recently began communication with some excellent collaborators who might be able to help move this technology forward. Hoping for some exciting progress!
