Researchers demonstrated that braiding and fusing particles known as non-Abelian anyons can perform every operation required by a quantum computer. A quantum computer becomes broadly useful only when it can perform any computation rather than a limited set of specialized tasks. Physicists have now demonstrated that unusual quantum objects called non-Abelian anyons can provide that [...]

By studying a gene associated with congenital heart defects, scientists uncovered a mechanism showing how small reductions in protein levels can disrupt DNA’s three-dimensional structure and lead to disease. A baby can inherit one healthy copy of TBX5 and still develop serious heart defects if the other copy does not work. That genetic imbalance is [...]
