Gold-coated glass "nanoshells" can reveal the location of tumours and then destroy them minutes later in a burst of heat, according to new research. When injected into the bloodstream, the particles accumulate at the site of a tumour. The tumour sites can then be identified using low-power infrared light, and destroyed by applying a high-power infrared laser
If the universe has extra-spatial dimensions in parallel to the 3D we are used to, they might be seen in areas of extreme gravity around dense stars
A device that can hold hundreds of atoms in a 3D array, and image each one individually, has been developed by scientists in the US. The machine is an important stepping stone towards the development of a quantum computer
Beyond Ethanol: Synthetic fuel offers promising alternative
A faster, simpler manufacturing technique could make a synthetic biofuel into an even stronger competitor to ethanol.
A quarry on the Virginia-North Carolina border has yielded fossils of an unusual gliding reptile that lived in the region about 220 million years ago.
