Leaf-mimicking device harnesses light to purify water

For years, scientists have been pursuing ways to imitate a leaf's photosynthetic power to make hydrogen fuel from water and sunlight. In a new twist, a team has come up with another kind of device that mimics two of a leaf's ...

Nanowalls for smartphones

Researchers at ETH Zurich have manufactured transparent electrodes for use in touchscreens using a novel nanoprinting process. The new electrodes are some of the most transparent and conductive that have ever been developed.

Globular clusters could host interstellar civilizations

Globular star clusters are extraordinary in almost every way. They're densely packed, holding a million stars in a ball only about 100 light-years across on average. They're old, dating back almost to the birth of the Milky ...

New efficiency record set with dual-junction solar cell

Scientists at the Energy Department's National Renewable Energy Laboratory (NREL) and at the Swiss Center for Electronics and Microtechnology (CSEM) have jointly set a new world record for converting non-concentrated (1-sun) ...

How to stop a castle falling into a river

Fierce storms and floods have made this a very difficult winter for many parts of the UK, not least the owners of a historic castle in Aberdeenshire, close to the Queen's residence at Balmoral. Some 20 metres of land behind ...

Fish ladders promote genetic exchange

Hydroelectric power plants, weirs and waterfalls are often insurmountable barricades for fish. This can have a significant impact on the genetic structure of the separate populations. Whether and to what extent fish ladders ...
