Global warming poses an increasingly sizeable threat to the continued existence of man. James Lovelock, atmospheric chemist and author of Gaia warns that the gravity of the situation facing Earth’s inhabitants is greater than we have yet realized and accepted. Lovelock sets forth his predictions -- and proposed solutions -- in a commentary piece published this week in Atmospheric Science Letters.
The laws of Gaia - a hypothesis set forth by Lovelock - imply that any species that makes changes in the composition of the air and the nature of the land surface risks altering the world to a state that will disfavour its progeny. In other words, if humans continue in their current path of alteration of the environment, they will become a target of elimination from the world.
In his commentary, Lovelock outlines the two major approaches to the threat of global warming. One approach, adopted by some, is to deny the existence of global warming and enjoy more temperate climates while they last. Others recognize the threat but choose to react in the Green way, eating organic foods, using renewable energy sources and alternative medicines. Lovelock argues that taking either of these approaches will ultimately result in the elimination of humans as well as civilization.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
