Computer security researchers suggest ways to thwart new form of cybercrime
Most experts on computer crime focus on attacks against Web servers, bank account tampering and other mischief confined to the digital world. But by using little more than a Web search engine and some simple software, a computer-savvy criminal or terrorist could easily leap beyond the boundaries of cyberspace to wreak havoc in the physical world, a team of Internet security researchers has concluded.
At a recent Association for Computing Machinery conference on privacy in an electronic society, the researchers -- including a Johns Hopkins faculty member -- described how automated order forms on the Web could be exploited to send tens of thousands of unwanted catalogs to a business or an individual. Such an onslaught would not only pose problems for the victim, but it could also paralyze the local post office charged with making such deliveries, the researchers suggested. After explaining how such attacks could take place, the researchers proposed several technological "fixes" that could help prevent them.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
