In a new Nature study, Columbia Engineering researchers have built a photonic chip that is able to produce high-quality, ultra-low-noise microwave signals using only a single laser. The compact device—a chip so small, it could fit on a sharp pencil point—results in the lowest microwave noise ever observed in an integrated photonics platform.

The achievement provides a promising pathway towards small-footprint ultra-low-noise microwave generation for applications such as high-speed communication, atomic clocks, and autonomous vehicles.

The challenge Electronic devices for global navigation, wireless communications, radar, and precision timing need stable microwave sources to serve as clocks and information carriers. A key aspect to increasing the performance of these devices is reducing the noise, or random fluctuations in phase, that is present on the microwave.

A 63-hour-long marathon of GPS jamming attacks disrupted global satellite navigation systems for hundreds of aircraft flying through the Baltic region – and Russia is thought to be responsible.

Leading EV battery maker CATL released its new breakthrough battery pack with up to a nearly 1 million mile (1.5 million km), 15-year warranty.

CATL launched the battery pack with Yutung Bus Co to power commercial vehicles like buses and different classes of trucks.

Yutong, one of China’s largest bus makers, said the new battery packs will be used in upcoming electric vehicles. According to the company, the new long-lasting EV battery has zero degradation through the first 1,000 cycles.

Apple is reportedly exploring the development of ‘home robots’ as its next big venture.

According to Business Insider, tech giant Apple is shifting its focus towards a new area of development.

The pivot comes after a difficult period for Apple, with the company scrapping its plans to develop a self-driving car, which it had been working on for years.

A Tesla engineer has given a rare update on the Tesla Semi electric truck program amid new EPA rules that should give it a boost.

Tesla Semi is currently only in low-volume production at a facility outside Gigafactory Nevada.

In January 2023, Tesla announced a massive expansion of Gigafactory Nevada to add production of Tesla Semi trucks and 4,680 battery cells and to finally expand the factory to its originally planned size.

Cars today roll along a production line where components are added at set stations and Tesla now wants to implement a completely new assembly process.

DARPA and Boeing’s Aurora are moving ahead with their research into the creation of an active flow control aircraft with no control surfaces.
