You’re probably reading this article on a phone or laptop containing more than 30 different metals. Some will be common: aluminium casing, copper wires. But other metals are less familiar and much more scarce. Each iPhone contains less than a gram of lithium, for instance, but would not function without it.

We are in the midst of a geopolitically charged race for lithium and other so-called critical minerals. These materials are crucial for renewable energy, transport, data centres, aerospace and…The Conversation (Full Story)

Can tattoos protect your skin from the sun’s harmful rays, or do they make things worse? A new study I conducted with colleagues suggests there may be cause for concern. We found that people with tattoos had a 29% higher risk of developing melanoma, a serious form of skin cancer often linked to ultraviolet (UV) exposure.

However, tattoos did not appear to increase the risk of squamous cell carcinoma, another type of skin cancer related to UV damage. Although both cancers share a common cause, they arise…The Conversation (Full Story)

In the animal kingdom, penises can be spiked, split, corkscrewed – even detachable. They’re one of the most diverse structures in biology. The human penis is so uniform, it’s an anatomical outlier. Understanding why penises evolved, and why they differ so widely, also helps explain why humans have one at all.

Penises first evolved as a solution to one simple problem: how to achieve internal fertilisation.

The first animals lived in the sea before our ancestors started living…The Conversation (Full Story)

Economic abuse may not be as obvious as physical abuse, but for the millions of people it affects in the UK, economic abuse can be totally devastating.

Economic abuse, which is recognised as a form of domestic abuse in law, involves controlling a person’s (often a woman’s) ability to acquire, use and maintain economic…The Conversation (Full Story)

As a public health dentist and researcher, for years I saw the same pattern. Patients with deep root infections often had wider health problems, particularly those with diabetes. I did not yet understand why. Now, scientific studies are beginning to explain the link: treating a deep tooth infection may also help the body manage blood sugar.

A tooth infection might seem like a relatively minor health issue, but its effects can reach far beyond the mouth. Recent…The Conversation (Full Story)
