This theory suggests that in its early history the Earth suffered glaciations so major that it froze over completely. It remains controversial, but has proved extremely fruitful for our understanding of how the Earth system functioned many hundreds of millions of years ago.
In a 1998 paper, Hoffman proposed that a drop in the level of carbon dioxide in the atmosphere 750 million years ago caused a global fall in temperature that very nearly wiped out all life on Earth. Hoffman’s most significant impact on Earth science has arisen from his development of holistic models of geological processes during the Precambrian (c. 4500 – 542 million years ago). The scope of this subsequent work shows a remarkable interdisciplinary understanding, and stands as an exemplary model of how Earth science research should be conducted.
The Wollaston Medal (named for William Hyde Wollaston 1766-1828, the discoverer of the element Palladium, in which the medal is struck) was first awarded in 1831 to William Smith, known as “the father of English Geology”, who is credited with creating the first geological map of Britain. It was bestowed on Charles Darwin in 1859 - the same year in which On the Origin of Species was published. The award, made some months earlier, was given in recognition of Darwin’s “judicious and vigorous efforts on some of the harder problems of geology”.
Past recipients of the Wollaston also include Richard Owen, founder of the Natural History Museum in London; William Buckland, who published the first full description of what would later become known as the dinosaur, and Charles Lyell.
In addition to the Wollaston medal, the society made the following awards for 2009.•Wollaston Medal - Prof. Paul Hoffman (Harvard University)

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
