Science On Why Banana Leaves Have Been a Part of Indian Food For Centuries

Posted by in categories: food, health, science

Whether it is steamed idli, Gujarati snack, panki; Parsi’s patra ni machchi, Assam’s bhapot diya maach or the elaborate Onam Sandhya from Kerala, the humble banana leaf has found its way into many cuisines.

It is also very versatile as food can be steamed, grilled and deep-fried. It can also be used as a serving plate and packaging material.

While banana leaves have been an integral part of the desi food and traditions, did you know there are health benefits to it as well?

Webb telescope makes a surprising galactic discovery in the distant universe

Posted by in categories: physics, space

“These objects are way more massive than anyone expected,” said study coauthor Joel Leja, assistant professor of astronomy and astrophysics at Penn State University, in a statement. “We expected only to find tiny, young, baby galaxies at this point in time, but we’ve discovered galaxies as mature as our own in what was previously understood to be the dawn of the universe.”

The telescope observes the universe in infrared light, which is invisible to the human eye, and is capable of detecting the faint light from ancient stars and galaxies. By peering into the distant universe, the observatory can essentially see back in time up to about 13.5 billion years ago. (Scientists have determined the universe is about 13.7 billion years old.)

The operations center for the telescope is in Baltimore City, at the Space Telescope Science Institute on the Johns Hopkins campus.

Russia launches rescue ship to space station after leaks

Posted by in categories: habitats, space

Russia launched a rescue ship on Friday for two cosmonauts and a NASA astronaut whose original ride home sprang a dangerous leak while parked at the International Space Station.

The new, empty Soyuz capsule should arrive at the orbiting lab on Sunday.

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.

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.
