Japanese scientists from the NIMS International Center for Materials Nanoarchitectonics (MANA) have developed a nanostructured sheets film capable of introducing designated genes into animal cells. The...
View ArticleExperiments may reveal new state of matter for the 'glue particles', the gluons
(Phys.org)—At the LHC accelerator at CERN, collisions between protons and lead nuclei were established last week, for the first time in the ALICE detector.
View ArticleYou don't exist in an infinite number of places, say scientists
(Phys.org)—If you've read about how modern cosmology may imply that, in an infinite universe, the existence of planets and the life forms that live on them must be repeated an infinite number of times,...
View ArticleCalculating quantum vacuum forces in nanostructures
(Phys.org)—One of the surprising predictions of quantum mechanics is that uncharged conductors can attract each other over small distances, even in empty space. While the resulting "Casimir force" has...
View ArticleGel or whitening? Consumer choice and product organization
Consumers choose lower-priced products and are more satisfied with their purchase when products are organized by benefits instead of features, according to a new study in the Journal of Consumer Research.
View ArticleMathematician unleashes 'a wave of new results' in geometric analysis
It's something children do every day when blowing bubbles: Stick a circular wire in a pot of soapy water, pull it out, and behold the film forming across it.
View ArticleChildren's book explores Really Big Numbers
A new children's book written and illustrated by a Brown mathematics professor Richard Schwartz takes readers on a visual journal through the infinite number system. Schwartz hopes Really Big Numbers...
View ArticleIs the universe finite or infinite?
Two possiblities exist: either the Universe is finite and has a size, or it's infinite and goes on forever. Both possibilities have mind-bending implications.
View ArticleThe theory of parallel universes is not just maths – it is science that can...
The existence of parallel universes may seem like something cooked up by science fiction writers, with little relevance to modern theoretical physics. But the idea that we live in a "multiverse" made...
