The most transparent, lightweight and flexible material ever for conducting electricity has been invented by a team from the University of Exeter. Called GraphExeter, the material could revolutionise the creation of wearable electronic devices, such as clothing containing computers, phones and MP3 players.
As for weather extremes, for the climate average too a smaller-chance-higher-risk range exists, as indicated by the light-blue climate model members to the right.
It has been know for some time that large quantitites of methane lie hidden in reservoirs under the permafrost layers on the tundra and in clathrates on the continental shelve. It is neither a secret that those large quantities of … Continue reading
Several hundreds of millions of people in Southeast Asia depend, to varying degrees, on the freshwater reservoirs of the Himalayan glaciers. Consequently, it is important to detect the potential impact of climate changes on the Himalayan glaciers at an early stage. Together with international researchers, glaciologists from the University of Zurich now reveal that the glaciers in the Himalayas are declining less rapidly than was previously thought. However, the scientists see major hazard potential from outbursts of glacial lakes.
Living systems owe their existence to a pair of information-carrying molecules: DNA and RNA. These fundamental chemical forms possess two features essential for life: they display heredity — meaning they can encode and pass on genetic information, and they can adapt over time, through processes of Darwinian evolution.
A long-debated question is whether heredity and evolution could be performed by molecules other than DNA and RNA.
A large diversity of gasses in the atmosphere influence air quality, climate change and the recovery of the ozone layer. Measuring the concentrations of these gases in the atmosphere is quite straightforward. But pinpointing wether the gasses are a natural … Continue reading
In a study appearing this month in the journal Environmental Science and Technology, MIT researchers report that emissions from cars, trucks, planes and powerplants cause 13,000 premature deaths in the United Kingdom each year.
