Data

Last year a longstanding conspiracy was reignited, telling the tale of how your smartphone is listening to your conversations and delivering targeted ads, but it still isn't true and the way you actually get your ads is much more unsettling.

Meta (formerly Facebook) plans to build the world's longest undersea cable that will be longer than the Earth is round. The high-capacity, fiber-optic cable that will link five continents will span a fantastic 31,000 miles (50,000 km).

Scientists at the University College London have set a new world record in wireless data transmission speeds, sending a blistering 938 Gigabits per second (Gbps) over the air through a combo of radio and light technology.

A full DNA computer is a step closer, thanks to a new technology that could store petabytes of data in DNA for thousands or even millions of years. The system can also process data, as demonstrated by solving sudoku puzzles.

DNA is a much denser data storage medium than anything humans can design, but the problem is that it’s fragile. So now scientists have taken another page out of nature’s book and created artificial amber to protect data stored in DNA longer term.

An international research team has sent an astounding amount of data at a nearly incomprehensible speed. It's the fastest data transmission ever using a single optical fiber and shows just how speedy the process can get using current materials.

You can cram much more quantum processing power into a given space if you use four different ways to store data on a single atom, according to new research. The method unlocks more powerful quantum computers that are easier to control.

Diamond is a promising material for data storage, and now scientists have demonstrated a new way to cram more data onto it, down to a single atom. The technique bypasses a physical limit by writing data to the same spots in different-colored light.

Everybody wants a faster internet connection, and now engineers in Japan have shattered the record for data transmission. The team managed to transmit more than 20 times the global internet traffic per second through a single optical fiber.

10,000 years in the future, explorers could end up getting rickrolled, thanks to a Global Music Vault due to be built in Norway. It features Microsoft’s Project Silica, a tough new data storage medium that’s never gonna give you up.

Cambridge scientists have developed a new prototype for computer memory that could make for faster chips that could hold up to 100 times more data. The system is made up of barium bridges between films of a disordered material.

A team of international researchers say they’ve set a new world speed record for an industrial standard optical fiber that’s as thick as a human hair, achieving a data transmission rate of 1.7 Petabits per second over a 41-mile cable.
