Driving a car with poor visibility and tons of blind spots can be annoying at best and a safety concern at worst. So, having surround-view cameras (also called 360-degree, bird's-eye, or panoramic-view systems) can be a godsend, especially if you need help mastering parallel parking or any other parking scenarios. The system cleverly pieces together information from all the high-resolution cameras and projects it onto your car's display screen, with some camera systems allowing drivers to see what's underneath the car as well. Of note are the latest versions, where the digital processing is so impressive that it's difficult to tell how multiple cameras piece everything together so efficiently, despite various levels of lighting and glare.

House of the Dragon

Sunday evening’s episode of House of the Dragon is notable mostly for our full introduction to one of the most powerful men in the Seven Kingdoms, Lord Ormund, Lord of the Hightower and head of House Hightower, and a very . . . singular man. He’s shaping up to be one of the more compelling villains (or heroes, I suppose, if you’re on Team Green) in the series.

Senior police figures and politicians have warned against speculation during the murder investigation into Ann Widdecombe’s death, after detectives said there was “nothing to suggest” political motivation following an intervention from Nigel Farage.

Two men have died after going into the water at a beach in County Durham to try to help two children who had gotten into difficulty, police said.

Officers were called at about 3.45pm on Sunday after concerns were raised about two youngsters in the water at Seaton Carew beach in Hartlepool.

Microsoft PowerPoint has become the default tool for presenting learning materials in classrooms, universities, corporate training programs, webinars and remote learning environments. But is it being used effectively? This question arises because learners face a major challenge. They try to listen to the speaker's explanations while simultaneously connecting them to the relevant visual elements on the slide, which can interfere with learning.

Light Emitting Diodes (LEDs) are used in everything from household lighting and mobile phones to large display screens. Improving their efficiency could reduce energy use and enhance performance across a wide range of technologies. A new study involving researchers from the University of Liverpool and the University of Strathclyde has demonstrated a powerful way to identify tiny crystal defects that can reduce the efficiency of LED materials. The advance could help scientists better understand how these defects form and ultimately support the development of more efficient electronic and optoelectronic devices.
