The dyes which are injected into the skin to create tattoos move with time – permanently altering the look of a given design. In this month’s Mathematics Today Dr Ian Eames, a Reader in Fluid Mechanics at UCL, publishes a mathematical model enabling us to estimate the movement of these ink particles and predict how specific tattoo designs will look several years in the future.

“Tattoos are incredibly popular worldwide with more than a third of 18-25 year olds in the USA sporting at least one design,” says Dr Eames. “A great deal of work has already been done on the short term fate of ink particles in the skin, tracking them over periods of just a few months – but much less is known about how these particles move over longer periods of time.

*Pyrite nanoparticles from hydrothermal vents are a rich source of iron in the deep sea*

Similar to humans, the bacteria and tiny plants living in the ocean need iron for energy and growth. But their situation is quite different from ours–for one, they can’t turn to natural iron sources like leafy greens or red meat for a pick-me-up.

So, from where does their iron come? (more…)

Health benefits of walnuts have been known since time immemorial. Hippocrates and Avicenna mentioned them in the treatment of various diseases. In addition, the ancients thought that they stimulate mental activity. Anna Protsenko, a nutritionist, told MedPulse.ru.

“Walnuts contain a great deal of minerals,” the expert explains. “They include iron, copper, cobalt, potassium, sodium, phosphorus, magnesium, calcium, and iodine. Many of them are antioxidants.

In Afghanistan, American geologists have discovered deposits of iron, copper, lithium, cobalt, and gold worth $1 trillion.

Experts believe that these reserves may not only stop the poverty in one of the poorest countries in the world, but turn Afghanistan in a flourishing country and one of the largest centers of natural resources excavation.
