Each year over 3.5 million tourists from all over the world visit Pompeii to admire the ruins left by the eruption of the Vesuvius that, in 79 AD, engulfed it together with the nearby city of Herculaneum.

As future covid-19 prevalence varies across time, health authorities must revolutionise testing to see if people are infected.

The success of lithium-ion batteries is so great that it’s easy to ignore how common they now are – except on the rare occasion one bursts into flames. That success arguably originated with M.

Long-touted advances of smart cities may finally become reality with the increases to wireless network speeds and bandwidths promised by the switch to 5G .

In our fast-moving world, biotech is at the forefront of developments – but, by its very nature, it can provoke ethical and moral concerns .

If aliens were to examine a human, they would think we were just slavish organisms designed to feed microbes and carry them around. Our bodies contain ten times more bacteria than cells , and there are an estimated 3.

In January 2005, a severe storm swept across Northern Europe, from Ireland to Russia. More than 500,000 homes were left without power, with Denmark and Southern Sweden being particularly hard-hit.

Traditionally our electricity grids were designed to move power from large nuclear and fossil fuel power plants to consumers, but renewable energy will see changes to allow smaller power generation from wind and solar to be hooked up to the grid.

Lysosomes are membrane-bound organelles found in most animal cells. They are responsible for treating cellular waste. Genetic mutations in lysosomal enzymes lead to lysosome malfunction and waste accumulation.

Silver has been used as biocide for medical purposes since the 1930s. Today nanometric size silver particles are used to prevent unpleasant odour caused by bacteria in sport shirts or socks .

Several hundred thousands of Europeans are affected by food borne diseases every year . Only a shift in perception of how food safety should be achieved could help avoid these illnesses.

Membranes for water purification are used in many applications and different types of membranes are being developed at the moment. No membrane can filter and purify water entirely, but improvements using novel kinds of membranes are made.

Researchers are trying to find out more about the relationship between different NPs’ shapes, sizes and surface chemistries and how they behave in the human body.

The filter could be used to recycle sewage on a space station, but the main focus is the use of ultra pure water in the fabrication of semiconductors.
