Bouquets of nanoflowers with a golden touch

Using nano-sized spheres as a starting point, researcher Juan Wang of the University of Twente (MESA+ Institute) creates fascinating structures that can have a wide range of shapes and functionalities. They can even achieve ...

A spookily good sensor

Scientists from the Research Center for Advanced Science and Technology (RCAST) at The University of Tokyo demonstrated a method for coupling a magnetic sphere with a sensor via the strange power of quantum entanglement. ...

ESO telescope sees surface of dim Betelgeuse

Using ESO's Very Large Telescope (VLT), astronomers have captured the unprecedented dimming of Betelgeuse, a red supergiant star in the constellation of Orion. The stunning new images of the star's surface show not only the ...

Chemist develops flower-like catalysts from graphene

A RUDN chemist and colleagues from Iran have developed a new strategy for producing hollow, porous catalysts for the Heck coupling reaction. These catalysts are characterized by a flower-like structure. They consist of graphene, ...

Deflating beach balls and drug delivery

Many natural microscopic objects—red blood cells and pollen grains, for example—take the form of distorted spheres. The distortions can be compared to those observed when a sphere is 'deflated' so that it steadily loses ...

Nanoscale 'glass' bottles could enable targeted drug delivery

Tiny silica bottles filled with medicine and a special temperature-sensitive material could be used for drug delivery to kill malignant cells only in certain parts of the body, according to a study published recently by researchers ...

Managing mutations of a species: the evolution of dog breeding

In the first edition of On the Origin of Species, Charles Darwin mentions dogs 54 times. He does so mainly because the extraordinary variation between dog breeds provides a marvellous illustration of the power of selection. ...
