Gmail adds an official 'Undo Send' tool to stop embarrassing emails getting to the wrong people

For those of us who want to send a mail and you send it to the wrong person, or you want to make a bad decision and then change your mind or just generally send mails to the wrong person and or change your mind about sending a mail, there's a solution, thanks to Google.

If you've ever hit send on an email only to realise you've sent it to the wrong person, you'll know the feeling of dread that hits the pit of your stomach.

But thankfully, for Gmail users at least, there is now a solution to spare any future blushes.

Google has made its 'Undo Send' tool an official and permanent feature nearly six years since it launched as an experiment in Gmail Labs. 

This is currently available for five, 10, 20 or 30 seconds and effectively delays the message being sent for up to half a minute to give users time to change their mind.

Teen geniuses invent condom that change colour when in contact with STIs

A group of teenagers have invented a revolutionary condom which changes colour when it comes into contact with sexually transmitted infections (STIs).

History has been made as a couple of teen geniuses have given mankind a chance to have even safer sex.

Daanyaal Ali, 14, Muaz Nawaz, 13, and Chirag Shah, 14, students of Isaac Newton Academy in London, have created the ‘S.T.EYE’ condom and it can detect harmful STIs.

The condom has a built-in indicator, this makes it change into a different colour every time it comes into contact with a different strain of bacteria.
