Should GM crops be grown in the EU? Let the countries decide for themselves, propose a group of experts

Even though the EU’s food safety authority, EFSA, has classified genetically modified (GM) crops as safe, several member states always vote against authorisation, which poses an obstacle for countries thinking of growing these crops. A group of researchers and experts want to resolve this impasse. Each country should be allowed to individually decide on cultivation of GM crops within their borders

Silver atom nanoclusters could become efficient biosensors

Researchers have now managed to pinpoint what happens when light is absorbed by extremely small nanoclusters of silver atoms. The results may have useful application in the development of biosensors and in imaging. By combining chemistry and nanotechnology, the research community in recent years has developed a kind of extremely small nanoclusters consisting of only a few noble metal atoms bound t

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

Well managed forests can limit climate change

Growing forests can limit climate change by absorbing carbon dioxide from the atmosphere and store the carbon in their biomass as they grow. How much carbon a forest stores varies between tree species, the forests age, weather conditions and how the forest is managed. Young growing forests store a lot of carbon, as the forest gets older the carbon sequestration capacity decreases. When trees are f
