Scientists create “Dr Who sonic screwdriver”
This fails on the following levels:

Quotation in Headline
I’m pretty sure they used the quotation marks here to show that they “just made it up”. Having looked at the article the reference to Dr Who was made by one of the researchers who is obviously trying to get into the news cycle so he can keep his research grant. In reality it’s an ultrasound device that can turn objects under specific conditions not just make them move backwards and forwards as sound waves would normally do. Now this is very clever but I’m pretty sure that Dr Who doesn’t use an ultrasonic screwdriver. All the references in the shows are to a sonic screwdriver that is the biggest deus ex machina device I have seen and turned me off the show.
Extrapolation
The BBC writers researchers obviously got a little excited and decided that if they followed the technological line for a few thousand iterations then we could link this current device to the Doctor’s sonic screw driver. This is rubbish. It’s like saying that because cars have improved their fuel efficiency over the last decade we should be able to travel miles on a thimble of fuel some time in the future.
Bull
It’s just rubbish to suggest that this device is anywhere near a sonic screwdriver.
