Physicists report that they have developed a new system to trap individual excitons — bound pairs of electrons and their associated positive charges. Their system could form the basis of a novel expe..

In recent years, electronic data processing has been evolving in one direction only: the industry has downsized its components to the nanometer range. But this process is now reaching its physical lim..

Why can some people patiently save for the future, while others opt for fewer dollars now? A new study reaches some surprising conclusions. Saving takes patience — forgoing instant rewards for larger..

The Argonaute (Ago) enzyme complex plays a critical role in DNA and RNA target cleavage for a process known as RNA silencing in prokaryotic and eukaryotic cells, making them a target for future gene-e..

Researchers have discovered a new and rare skeletal disease. They describe the molecular mechanism of the disease, in which small RNA molecules play a role that has never before been observed in a con..

Efforts to cut emissions of carbon dioxide (CO2) and tackle climate change in developed economies are beginning to pay off according to new research.

When an epileptic seizure occurs in the brain, the nerve cells lose their usual pattern and fire in a very fast rhythm. The cause is a complex interplay of various factors. Scientists have now discove..

Scientists have discovered a defect in immune cells known as 'killer T cells' that explains their inability to destroy cancer tumors. The researchers believe that repairing this defect could..

Using two partially fragmented fossil skulls, a student has digitally reconstructed, in three-dimensions, the skulls of two species of ancient reptile that lived in the Late Triassic, one of which had..

We are more likely to have positive feelings about transitioning from one stage of life to the next if we have a 'well-rounded ending' — or one marked by a sense of closure — finds a team ..
