Deforestation in Amazon basin could disrupt the distant rainforest by remote climate connection

Minchao Wu The ongoing deforestation around the fringes of the Amazon may have serious consequences for the untouched deeper parts of the rainforest. A new research study shows that it is not only the climate that is adversely affected by deforestation. In fact, the very stability of the ecosystem in the entire Amazon region is altered when deforestation takes place in the outermost regions.

The world’s largest canary

Silver atom nanoclusters could become efficient biosensors

Cholesterol - a key player at the lung surface

Cholesterol, a naturally occurring compound at the lung surface, has been shown to have a clear effect on the properties of this nanoscale film that covers the inside of our lungs. Cholesterol levels in this system may affect the lung’s function, according to researchers at Lund University in Sweden who have published a new study on the significance of cholesterol for lung surface properties. The new findings provide new insights into this vital physiological system.

Knowledge gap on the origin of sex

Even after more than a century of study, researchers do not know enough about the evolution of sex chromosomes to understand how males and females emerge.

Solar cells more efficient thanks to new material standing on edge

The illustration shows sheets of perovskite, side view. The coloured pattern represents perovskite and the grey lines symbolise the water-repelling surfaces. Researchers from Lund University in Sweden and from Fudan University in China have successfully designed a new structural organization using the promising solar cell material perovskite. The study shows that solar cells increase in efficiency thanks to the material’s ability to self-organise by standing on edge.

Even non-migratory birds use a magnetic compass

Zebra finch Not only migratory birds use a built-in magnetic compass to navigate correctly. A new study from Lund University in Sweden shows that non-migratory birds also are able to use a built-in compass to orient themselves using the Earth’s magnetic field.

Stem cells in plants and animals behave surprisingly similarly: study

Young plants A new study from Lund University in Sweden shows that the behaviour of stem cells in plants and animals is surprisingly similar. The researchers were able to produce mathematical equations that reveal very small differences in the behaviour of the proteins. The results can hopefully be used in stem cell research involving humans.

Bravery may cost fish their lives

Researchers at Lund University in Sweden have now successfully established a connection between bold personalities and the risk of being killed by a predator in the wild.

Completed mapping of barley’s DNA stands to revolutionise plant breeding
