But scientists say human effects can be a positive, not negative, factor for life on earth
Human beings now directly influence more than three quarters of the earths landmass, according to a state-of-the-art map of the world produced by a team of scientists from the New York-based Wildlife Conservation Society (WCS) and Columbia Universitys Center for International Earth Science Information Network (CIESIN). Published in the latest issue of the scientific journal BioScience, the map should serve as a wake-up call that humans are stewards of the natural world, whether we like it or not – something that should be viewed as an opportunity, the authors say.
The map adds together influences from population density, access from roads and waterways, electrical power infrastructure, and land transformation such as urbanization and agricultural use. It reveals that 83 percent of the lands surface is under human influence, while a staggering 98 percent of the area where it is possible to grow rice, wheat or maize is directly influenced by human beings. At the same time, wide swaths of land still remain wild, including: the northern forests of Alaska, Canada and Russia; the high plateaus of Tibet and Mongolia; and much of the Amazon River Basin.

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...
