Transmission

NASA’s Psyche spacecraft, farther away than the Sun, has sent data through a laser over a record-breaking distance, and done so even faster than expected. The breakthrough could help establish high-speed communications with human colonies on Mars.

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.

The Orbit Drive promises an ebike transmission, built into the motor housing, that lasts for thousands of miles without maintenance, boosts efficiency and range, allows regenerative braking, and comes out lighter than most ebike drive systems.

A small satellite developed by MIT engineers has set a new record for data transmission between a satellite and Earth. The TeraByte InfraRed Delivery (TBIRD) system used a laser to beam huge amounts of data at up to 100 gigabits per second.

Engineers have set a new speed record for data transmission through a standard diameter optical fiber. By beaming 55 “modes” of signals down a single-core optical fiber, the team was able to transmit at a data rate of 1.53 petabits per second.

Researchers in Japan have clocked a new speed record for data transmission – a blistering 1.02 petabits per second (Pb/s). Better yet, the breakthrough was achieved using optical fiber cables that should be compatible with existing infrastructure.

New research published in Nature Medicine has found COVID-19 vaccination can reduce a person’s infectious viral load. The study compared the infectiousness of different SARS-CoV-2 variants in vaccinated and unvaccinated subjects.

The first bikes using Valeo's smart ebike system will roll off production lines within months. Fourteen manufacturers have signed on to begin using this high-torque integrated powertrain, with its built-in 7-speed automatic transmission and belt drive.

The record for fastest internet speed has been shattered with a data transmission rate of 319 Terabits per second through optical fibers. The record was set over more than 3,000 km of fibers, and is compatible with existing infrastructure.

Music lovers who want to stream tunes from their smartphone to the home hi-fi or from the hi-fi to Bluetooth headphones might be disappointed. McIntosh Labs engineered the MB20 Bluetooth Transceiver to enable any hi-fi setup to do just that.

A review article has presented 10 key scientific reasons why the virus that causes COVID-19 is predominantly spread though the air. The research adds to a growing chorus of experts saying the evidence for airborne transmission is “overwhelming”.

A new internet speed record has been clocked at an incredible 178 terabits per second (Tb/s) – fast enough to download the entire Netflix library in under a second. It's achieved by modulating light in new ways before beaming it down optical fibers.
