Why do some birds bob their heads when they walk? For many birds, head bobbing accompanies walking, giving them a rather distinctive appearance. It would seem as if they do this to keep equilibrium... or is it for another reason?

The inside of a microchip is a mysterious thing. Here, we zoom into a microchip using a digital SLR camera then we transition to a scanning electron microscope, aka SEM. Although this is an older microchip, many of the same principles still apply to microchip design but with much, much smaller structures measured in nanometers instead of microns.

I love sharing my photography and am always looking for new ways to make the experience of viewing photography more rewarding. Maybe a photo zine will bring some of the joy that social media doesn't?

Here's a link to the Photo Zine :)

Somehow I'm reminded of this.

Video description:

The same biscuit, from the same factory, costs 60% more in the UK — and the company that did it got fined €337 million. So why is nobody here doing anything about it?

In this video, I trace your food bill from the checkout to the boardroom. I look at who really controls UK food prices (spoiler: it's five companies in fancy dress), why farmers get a tenth of a penny profit on a loaf of bread while manufacturers pocket 17%, and what happened when the EU caught one of the world's biggest food corporations rigging prices across borders.

Then I dig into the UK side — the regulator that found the evidence and walked away, the nutrition panel where 11 out of 17 advisors have food industry money, the 1,408 meetings between food ministers and industry versus 35 with charities, and the one government statistic that would have made the whole thing obvious… that quietly disappeared.

Slap that video!

I really liked the setup of the video where he first discussed his own ideas and then spoke with a Comp-Sci professor in the second part to see how those ideas differed to his.
