There is a patent demand in the pharmaceutical, cosmetic and chemical industry for new alternative testing in order to assess the acute toxicity of new drugs, cosmetic ingredients or industrial chemical products that have to be in contact with humans or the natural environment.
The aim is to reduce the time for and cost of studies for the development of new active elements and reduce the number of experimental animals. Equally, these tests enable direct work on human cell lines instead of on animals, in order to study the toxicity of the liver or kidney, amongst other organs.
To this end, the validation of this new in vitro work methodology, compared to the conventional in vivo one is urgently needed, not only by corporate industry but also by the European Directives themselves. Both REACH (the UE regulating body for chemical products) and the 7th amendment to the Directive on cosmetics propose the replacement in, the short term, of animal experimentation. Currently, while a number of animal testing procedures for toxicity have been successfully substituted by alternative methods, systemic toxicities require new strategic tests to reach a suitable level of safety for the consumer.

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
