When Earths sun expands into a red giant star in roughly five billion years, long after Earth has become uninhabitable, the hydrogen core will be burned out and the bloated outer shell will be cool and murky.
But according to new research by the University of Colorado at Boulder, such red giants still retain surface magnetic storms and coronas — the very hot and patchy outer atmosphere of the sun and sun-like stars — at temperatures of millions of degrees Fahrenheit that often signal
University of Colorado at Boulder researchers have found, ironically, that two pollutants – carbon dioxide and hydrocarbons emitted from agricultural forest trees – offset each other somewhat in mitigating air quality problems.
Carbon dioxide, believed by scientists to be a major factor in greenhouse warming, has been shown to reduce “agriforest” emissions of hydrocarbons that contribute to ground-based ozone pollution, according to CU-Boulder doctoral candidate Todd Rosenstiel of the envir
Technique could help bring efficiency of biology to man-made materials
A Princeton chemist has developed a general mathematical system for designing materials that perform two functions at once, even when the desired properties sometimes conflict with each other.
Salvatore Torquato and colleagues used computers to calculate the optimum structure for any material that is a composite of two substances with differing properties. The achievement is the first simple example of a
The biological clock – timekeeper for virtually every activity within living things, from sleep patterns to respiration – is a single protein, Purdue University researchers report.
The husband and wife team of D. James and Dorothy Morré has discovered this protein, which is responsible for setting the length of periods of activity and inactivity within cells. If the protein is altered, an organisms body will experience “days” of different length – ranging from 22 to 42 hours in
The University of the Basque Country, IBERDROLA (an electricity utility supplying the Basque Country), the enterprises INGETEAM and INDAR and innovative energies company EHN have participated jointly in this research project. The project has put forward an innovative use of wind-sourced energy to control fluctuations on the grid. The research site where measurements were made was the Salajones wind park in Sanguesa (Navarre).
In recent years the electricity utilities have shown much greater
An Australian scientist has made a discovery which is electrifying world fungal biology – a new truffle genus related to the famous Amanita family, or fairy toadstools.
The Amanita family is famed worldwide for the red and white-spotted toadstools beloved of children’s fairy tales, the lethal Death Cap beloved of tabloid media, and a range of delicious edible fungi beloved of gourmets.
The find, by CSIRO Forestry and Forest Products mycologist Dr Neale Bougher, highli
