In a recent advance, researchers have created a novel battery charger that can support present and future generations of battery packs for EVs across a vast range of voltages: anything between 120 and 900 volts. The new tech is described in a study published in the September edition of theIEEE Transactions on Power Electronics.

These next-generation batteries will bring shorter charging times while also weighing less, which means that EVs can be ready to drive sooner and travel farther on a full charge. “However, charging these high-voltage batteries with existing chargers degrades the efficiency, due to operating at twice the rated voltage,” says Deepak Ronanki, an assistant professor at the Indian Institute of Technology Madras, in Chennai, India, and an IEEE senior member who was involved in the study.

Ronanki and doctoral research scholar Harish Karneddi created a universal charger capable of supporting voltages between 120 and 900 V—something they say had not yet otherwise been achieved.

The world’s first wind-powered cargo ship has set off on her maiden voyage, using her giant metal ‘wings’ to fly through the ocean.

The WindWings have been fitted onto Mitsubishi-owned Pyxis Ocean — chartered by Cargill — and was designed by a team of British Olympic sailors.

It’s been built by Yara Marine Tech, and the WindWings are expected to save up to 30 percent of shipping fuel on average.

Salesforce is leading a financing round in Hugging Face, one of the most highly valued startups helping businesses use artificial intelligence, at a valuation north of $4 billion, according to two people with knowledge of the situation. The roughly $200 million funding round more than doubles the share price and private valuation of the New York–based company, one of these people said.

Salesforce is paying a high price for a piece of Hugging Face, which runs a service that helps companies store and use AI software, similar to the way GitHub lets developers store software code. The new funding valued the startup at more than 100 times its annualized revenue, a measure of how much revenue the company would generate over the next 12 months at its current rate, one of the people said.

The researchers had to look at light mechanically to begin seeing similarities in properties usually seen in quantum states.

In 1,673, Christiaan Huygens wrote a book on pendulums and how they work. A mechanical theorem mentioned in the book was used 350 years later by researchers at the Stevens Institute of Technology to explain the complex behaviors of light, a university statement said.

Although known to us for eons, humanity has found it difficult to explain the very nature of light. For centuries scientists have been divided on whether to call it a wave or a particle and when there seemed to be some agreement on what light could actually be, quantum physics threw a new curveball by suggesting that it existed as both at once.

People living in dry but foggy areas can benefit from this technology.

Researchers from ETH Zurich have developed a system that captures fog in the atmosphere and simultaneously removes contaminants while running using solar power.

The harvesting and water treatment system consists of a metal wire mesh with a solar-light-activated reactive coating that captures the fog. The droplets of water then trickle down into a container below. The mesh is coated with a mixture of specially selected polymers and titanium dioxide, which acts as a chemical catalyst and breaks down the molecules of the pollutants into harmless particles.

The Ring Nebula reveals intricate structures symbolizing a dying star’s final phases.

The James Webb Space Telescope has released new detailed images of the iconic Ring Nebula in never-before-seen detail. This planetary nebula’s intricate structure and composition can be seen in the new compelling images obtained by Webb’s Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI).

The Ring Nebula was discovered in 1,779 by astronomers Antoine Darquier de Pellepoix and Charles Messier. It is one of the most prominent and luminous objects in our night skies, approximately 2,500 light-years from Earth.

High-resolution 3D retina images have specific markers that can indicate the risk of Parkinson’s in a person. A new AI program can identify these markers and tell whether or not you have the disease.

Although Parkinson’s disease (PD) is incurable, a non-profit National Council of Aging report suggests that early detection and treatment could help patients live a long and productive life even with the disease.

Researchers use a mix of less expensive, safer, and sustainably available components to create long-lasting bi-functional air electrodes.

We have all heard the line; the future is electric. But are we fully equipped to handle a full-scale transition to all-electric power? One thing standing in the way is the lack of cleaner and more affordable battery technologies to store energy.

Compared to commonly used Lithium-ion cells facing challenges related to cost, finite resources, and safety concerns, rechargeable zinc-air batteries (ZABs) are pitched as cost-effective energy storage devices and display high-energy density, especially for application in EVs.

The report further says 40 percent of workers will need to polish their skills due to the implementation of AI.

Artificial intelligence (AI) won’t replace employees anytime soon. But people who use AI will replace people who don’t, said tech giant IBM in its report, which talks about the implications of AI in businesses.

Companies are rapidly introducing AI into their workings to free up their employees’ time so they can focus on issues that require their personalized attention. The thing about AI is that it will do exactly what you train it to do. So, the hyperboles around the latest technology snatching away people’s jobs and taking over humanity can calm down.
