Metasurface antenna could enable future 6G communications networks

A team led by researchers from the University of Glasgow has developed an innovative wireless communications antenna that combines the unique properties of metamaterials with sophisticated signal processing to deliver a new peak of performance.

Driver of electric Ford SUV was using automated system before fatal Texas crash, investigators say

The driver of a Ford electric SUV involved in a February fatal crash in Texas was using the company's partially automated driving system before the wreck, federal investigators said Thursday.

Making cement is very damaging for the climate. One solution is opening in California

It's a major contributor to climate change—the way buildings and roads are made with concrete. It's also a problem that's growing as more of the world develops. So the race has been on to find solutions for a material that's responsible for roughly 8% of global carbon dioxide emissions.

Uber and Lyft delay their plans to leave Minneapolis after officials push back driver pay plan

The ride-hailing companies Uber and Lyft said they will delay their planned exit from Minneapolis after city officials decided Wednesday to push back the start of a driver pay raise by two months.

Apple on Thursday promised it would stop a Palestinian flag emoji from being suggested to some iPhone users when they type "Jerusalem" in messages.

Japan seeks to reclaim tech edge with overseas help

Massive overseas and domestic investments offer Japan a chance to reclaim its tech crown, but to become a convincing alternative to China the country must embrace rapid innovation, experts say.

Is the shine coming off Japan's bullet trains?

Just 10 days before the 1964 Tokyo Olympic Games, Japan opened its Tōkaidō Shinkansen, a high-speed rail line connecting Tokyo with Osaka. Shinkansen bullet trains showcased the high quality of Japanese railway technology to the world, with trains traveling at up to 285 km/h (177 mph).

Large language models generate biased content, warn researchers

A new report led by researchers from UCL finds that the most popular artificial intelligence (AI) tools discriminate against women and people of different cultures and sexualities.

Sam Bankman-Fried appeals fraud conviction, 25-year jail term

Fallen cryptocurrency wunderkind Sam Bankman-Fried has appealed his federal conviction and 25-year jail sentence in a sweeping fraud case, according to a legal filing made public Thursday.

Science X Newsletter Mon, Apr 1

Dear manoj dole, Here is your customized Science X Newsletter for April 1, 2024: Technology news Using a 2D perovskite oxide as a photoactive high-κ gate dielectric Two-dimensional (2D) superconducting materials have been found to be promising for the development of miniaturized optoelectronic devices. To perform well while consuming less energy, however, these smaller devices require a higher gate capacitance (i.e., gates that can store more electrical charge in proportion to the voltage applied). An optimization-based method to enhance autonomous parking Vehicles that can drive themselves have been a long sought after goal both of robotics research and the automotive industry. While various companies have been investing in these vehicles and testing them, they have so far only deployed them in a limited number of settings. A
