In recent years, the plasma wakefield acceleration driven by ultra-short and ultra-intense laser pulses has become increasingly mature, which can produce electron beams with ultra-high beam density and femtosecond beam duration; By using this electron beam, a new table-top radiation light source with collimation, ultrafast and high brightness can be produced.…
The first 1PW laser was commissioned in the USA in the late 1990s with many systems globally coming on-line throughout the 2000s opening up new and exciting areas of science. In the following years many laboratories strived to increase the power, and hence the focussed intensity, to the 10PW regime, to realise new theoretical thresholds of fundamental science. Several lasers throughout the world, are in the process of construction/commissioning to achieve this goal in China, Romania, Czech Republic, and France with others planned in Japan, USA, Russia and the UK. The first of these systems, ELI-NP in Romania, has recently been the first to demonstrate this landmark achievement.
The pursue for high peak power is driven by the uncharted territory of knowledge that this may unlock, from basic science to applied one. The optical path towards these phenomenal powers may be one of the natural ones when we observe the critical role that the light is playing in the universe.
Ultrashort and broadband laser sources are formidable tools for a wide range of scientific areas. In the field of ultrafast science, laser pulses lasting only a few optical cycles are used to generate secondary sources employed in probing matter at atomic scales. Such sources are also widely adopted in applications in ultrafast spectroscopy, pump-probe in chemistry, and optical coherence tomography among many other fields.
Generation of electromagnetic waves was first demonstrated by Heinrich Hertz in 1887 and since then has become a leading subject of research, with an enormous range of applications covering radio communications, electronics, computing, radar technology and multi-wavelength astronomy.…
Archaeology and cultural heritage work have fully entered the digital age. Today, researchers rely on tools like 3D scanners, a variety of GIS software, and Lidar equipped drones to document the past in ways that were unimaginable just a few decades ago.…

How long will humankind survive? Besides the fact that we have been able to eliminate ourselves with nuclear weapons for decades, even without a third world war, the challenge to take care of the resources of our planet remains; we need to use them in a way that our children and their children can have a place on Earth as well. In this blog post Andreas Losch discusses his recent review article in the International Journal of Astrobiology, The need of an ethics of planetary sustainability

Q&A with Editor-in-Chief of the Precision Medicine Journal, Dame Anna Dominiczak, for International day of Women and Girls in Science
More and more research is finding inflammation as a potential contributing factor towards to the development of various mental illnesses. A systematic review was conducted to determine the association between parasitic infection and mental illnesses in various African populations. Two parasite groups were evaluated; helminths and protozoans, and four mental illness classifications; depressive disorders, anxiety disorders, schizotypal disorders and unspecified mental illnesses.
