Not seeing the tree…
Researchers have shown how it is possible that objects stand out less when they are surrounded by similar objects. This surroundings-suppressing effect is caused by feedback from higher visual brain areas. The results of this research are important for a better understanding of the way in which the brain transforms incoming light into a cohesive […]

New force…
Everything in our Universe is held together or pushed apart by four fundamental forces: gravity, electromagnetism, and two nuclear interactions. Physicists now think they’ve spotted the actions of a fifth physical force emerging from a helium atom. It’s not the first time researchers claim to have caught a glimpse of it, either. A few years […]

Blurry images…
The ghost imaging technique forms an image by correlating a beam that interacts with the object and a reference beam that does not. Individually, the beams don’t carry any meaningful information about the object. The imaging technique works with visible light, x-rays and other parts of the electromagnetic spectrum and, when the structured light beams […]

Learning new words…
Children may learn new words better when they learn them in the context of other words they are just learning – according to research from the University of East Anglia. Eighty two children took part in the study. In two experiments the team taught them some new words for things they couldn’t name – such […]

Cosmic-scale magnetic fields. Scientific models’ dirty little secrets…
While researchers have believed for some time that magnetic fields of femto-Gauss strength extend to the largest scales in the universe — to scales larger than the largest clusters of galaxies — it is an unresolved mystery how such magnetic fields can have been created in the early universe. One logical possibility is that the […]
