Rats are unwelcome visitors, and for most people getting rid of them means putting down poison, such as anticoagulant compounds based on warfarin.
Recent estimates suggest that rat populations are on the increase, and continued reliance on rodenticides as the only means of controlling rats may be building big problems for the future. The use of warfarin and similar poisons can present problems of its own, killing other wildlife and domestic pets and leading to ‘hotspots’ of super-rats that are out of control because they have evolved resistance to most or all of the poisons that can legally be used outdoors. These resistant super-rats are featured in the ITV1 programme, Filthy Homes from Hell, to be broadcast on Tuesday evening, 27 July 2004.
Research at the University of Leicester in collaboration with the Central Science Laboratory in York has investigated other ways of controlling the spread of Norway rat populations on farms in the UK, by managing the environment rats like to inhabit.

The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.
Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...
The well-known representation of chemical elements is just one example of how objects can be arranged and classified
The periodic table of elements that most chemistry books depict is only one special case. This tabular overview of the chemical elements, which goes back to...
Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.
The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...
Discovery by Brazilian and US researchers could change the classification of two species, which appear more akin to jellyfish than was thought.
The tube anemone Isarachnanthus nocturnus is only 15 cm long but has the largest mitochondrial genome of any animal sequenced to date, with 80,923 base pairs....
