MIT researchers develop high-temperature photonic crystals capable of efficiently converting heat to electricity, potentially allowing the creation of pocket-sized microreactors with ten times the efficiency and lifespan of current commercial batteries. As photonic crystals are already a relatively mature technology, the new invention could be commercialised in as little as two years.

A fly species, kept in complete darkness for 57 years (1,400 generations), showed genetic alterations that occurred as a result of environmental conditions, offering clear evidence of evolution.
British researchers identify key genes that "switch off" as the human body ages. These genes may be targeted by future
