The oxygen content increased when the Earth was covered in ice

In the beginning, planet Earth was a very inhospitable place with no oxygen and only single-celled bacteria as inhabitants. According to a new study, the oxygen content in the air began to increase about 2.4 billion years ago, at the same time as the global glaciation and when all continents were gathered in a single huge landmass, or supercontinent. How to explain the exact connection between the

Electrons used to control ultrashort laser pulses

We may soon get better insight into the microcosm and the world of electrons. Researchers at Lund University and Louisiana State University have developed a tool that makes it possible to control extreme UV light - light with much shorter wavelengths than visible light. The new method uses strong laser pulses to direct the short bursts of light. Something very exciting happens when light hits elec

Bacteria could become a future source of electricity

In recent years, researchers have tried to capture the electrical current that bacteria generate through their own metabolism. So far, however, the transfer of the current from the bacteria to a receiving electrode has not been efficient at all. Now, researchers from institutions including Lund University have achieved a slightly more efficient transfer of electrical current. One of society’s grea
