Freezing water is a central issue for climate, geology and life. On earth, ice and snow cover 10 percent of the land and up to half of the northern hemisphere in winter. Polar ice caps reflect up to 90...

For centuries, people in Baltic nations have used ancient amber for medicinal purposes. Even today, infants are given amber necklaces that they chew to relieve teething pain, and people put pulverized amber in elixirs and ointments for its purported...
A toxic pollutant produced by burning fossil fuels can be captured from the exhaust gas stream and converted into useful industrial chemicals using only water and air thanks to a new advanced material developed by an international team of...
Researchers at the Paul Scherrer Institute PSI have developed a new method to analyse particulate matter more precisely than ever before. Using it, they disproved an established doctrine: that molecules in aerosols undergo no further chemical transformations because they...
Peptides, short amino acid chains that control many functions in the human body, represent a billion-dollar market. But normally, peptide-based medications must be injected. A research team led by the Technical University of Munich (TUM) has now determined how...
Renewable sources of energy such as wind or photovoltaic are intermittent; production peaks do not necessarily follow the demand peaks. Storing green energy is therefore essential to moving away from fossil fuels. The energy produced by photovoltaic cells and...
Purdue researchers have observed a way that the brittle nature of ceramics can be overcome as they sustain heavy loads, leading to more resilient structures such as aircraft engine blade coatings and dental implants.
While inherently strong, most ceramics tend...
Using a state-of-the-art type of electron microscopy, an MIT-led team has discovered the structure of an enzyme that is crucial for maintaining an adequate supply of DNA building blocks in human cells.
Their new structure also reveals the likely mechanism...
In 2013, the Nobel Prize in Physiology or Medicine was awarded to three scientists for their contributions to uncovering the mechanisms governing vesicle transport in cells. Their explanations provided both a conceptual and a mechanistic understanding of basic processes...
Some materials are like people. Let them relax in the sun for a little while and they perform a lot better.
A collaboration led by Rice University and Los Alamos National Laboratory found that to be the case with a...
