Researchers propose that an observed rise in the ice-melting rate during the summer and an extension of the melting periods through October in the Alps may be caused by global warming. Vincent et al. analyzed more than 50 years of data showing the annual mass balance changes for two glaciers in the Alps and report anomalous ice melting that was likely caused by climate change.
The authors note an ice reduction of nearly half a centimeter [two-tenths of an inch] per day over the widely spaced glaciers, corresponding to a recorded 20 watts per square meter [two watts per square foot] rise in energy at the glacier surface since the 1950s.
The researchers note, however, that historical observations indicate that glaciers formed in the worlds mountainous regions during the Little Ice Age have slowly retreated since the end of that period. They suggest that the high ice depletion rates seen over the past 20 years is likely driven by warmer summer temperatures that may be initiated by human influences.

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...
