Transmission

A decade-long study of 35 million Americans in 10 states has found that group A streptococcus infections have more than doubled. What's more, "strep" – which can cause a bizarre flesh-eating disease – has become increasingly resistant to antibiotics.

In today’s edition of What the Heck, we have the case of Ford wanting to put what is essentially a fake manual shifter on its EVs. The company has applied for a patent that aims to bring back a traditional element of driving – the feel of shifting gears.

In the grand narrative of automotive history, Koenigsegg's Light Speed Tourbillon Transmission isn't just a new chapter; it's an entirely new volume of mechanical sorcery, making it the only production transmission to enable all-wheel drive with one electric motor.

The efficiency of a tooth-on-tooth geared transmission, with the smoothly variable gear ratios of a CVT – minus the belt friction and capable of going all the way down to a zero ratio without needing a clutch. That's a 'holy grail' level promise!

The Harmonic Drive is a key part of countless robotic applications. Incredibly simple yet quite odd to watch, this gear system is extremely precise with an impressive torque-to-weight ratio, even if it does wobble. So how does it work?

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.

KTM’s all-new Automated Manual Transmission (AMT) is rolling out on the upcoming 1390 Super Adventure, and the company says it'll change the way we ride motorcycles. It comes with a P–N–1–2–3–4–5–6 gear sequence – and of course, no clutch lever.

DJI, which nearly everyone knows as the drone company, made the jump into the electric mountain bike (eMTB) sector this year with the DJI Avinox Drive System. We just wanted to show you the clever inner workings of the setup, which brings some unique features to the table.

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.
