The MG HS is underwhelming to drive, with woolly steering and unsettled ride. The petrol engine is equally disappointing, but the plug-in hybrid model is rapid and should be cheap to run. Engines ...

MG needed to get a roadster to market in a hurry, and reworking its classic model gave it an easy solution. Despite (or maybe because of) the RV8 being based on a 30-year old model, its classic ...

Nov. 6, 2024 — Researchers have developed AI-driven mobile robots that can carry out chemical synthesis research with extraordinary efficiency. Researchers show how mobile robots that use AI ...

Polymerase chain reaction, or PCR, is a laboratory technique used to make multiple copies of a segment of DNA. PCR is very precise and can be used to amplify, or copy, a specific DNA target from a ...

If you’re feeling super generous, or just fancy having a chat about ‘the good old days’ of automotive, how about our pick of the best cars for Father’s Day? There’s a few classics in there, a few ...
