Although these paintings often seem to serve solely as a backdrop for Instagram snapshots, art history professor Minna Valjakka says there are rich traditions and intricate histories that uncover more critical…

How can a single origami crease pattern be folded into two precisely defined target shapes? Researchers at AMOLF and Leiden University have created an ‘alphabet’ of 140 origami ‘puzzle pieces’ that allows them to do just that, as described today in Nature Physics. This discovery could help in the construction…

Deep observations made with the MUSE spectrograph on ESO’s Very Large Telescope have uncovered vast cosmic reservoirs of atomic hydrogen surrounding distant galaxies. The exquisite sensitivity of MUSE allowed for direct observations of dim clouds of hydrogen glowing with Lyman-alpha emission in the…

Bodies come in all different shapes and sizes. For his PhD, Andries Hiskes researched the disabled body and the reactions it can bring.
