Researchers create a new element

With the manufacture of element number 115 - Ununpentium - science has added another element to the periodic table.

An international research team from the University of Lund in Sweden has created a new element - number 115 - by colliding two other elements in a giant particle accelerator in Germany. They thereby add an element to the periodic table, the large scientific overview of all elements in the universe.

The new element does not occur naturally, and if the researchers make it into a few atoms, the element disappears in less than a second.

Around the earth in a second

The researchers have made element 115 by hitting two lighter elements against each other. For a month they bombarded a thin foil of the element americium (atomic number 95) with ions of calcium (atomic number 20). Together, the two elements have 115 protons in their atomic nuclei, and as a result, their product became the element with atomic number 115. In the particle accelerator, the calcium ions were hunted up to approximately 30,000 kilometers per second. At that speed, the ions could travel around the earth in just over a second.

Heavier than uranium The substances produced in the laboratory have in common that they are heavier than uranium: element number 92 and the heaviest element in nature. That is why they are called transuric elements. Elements with atomic numbers higher than 104 are also transurane and also super heavy. Particle physicists hope to be able to create a super-heavy element that is stable enough to last for a few seconds. Nuclear physics calculations show that element 126 may be such a super heavy stable element.

Human flea brought plague to Europe

When the deadly plague prevailed in Europe in the mid-14th century, rats were not responsible for the spread. Until now, the common theory was that the plague bacterium Yersinia pestis was spread through the fleas of the black rat. However, this theory has been tested by researchers from the University of Oslo in Norway.

Multi-resistant bacteria: that's how dangerous they are

Resistant bakterier er ifølge susdenssundhedsorganisation WHO et kæmpe problem for verdens sundhed. Bakterierne opbygger nemlig resistens for the tilgængelige antibiotika i takt med, at vi prøver at treatment dem. Derfor er der efterhånden mange forskellige resistant bakterier iblandt os - og the splits.

The Black Death unraveled

The genetic material of one of the biggest killers ever, the plague bacterium Yersinia pestis, has now been mapped. The disease that she is transmitting, also known as 'the Black Death', has cost an estimated half of the European population in the 14th century in just five years. Johannes Krause of the University of Tübingen in Germany, together with British colleagues, searched for scraps of dried up blood and tissue in 46 teeth and 53 bones of four victims, who were buried in 1348 and 1349 in the East Smithfield cemetery in London.
