The ability of high-energy laser systems to provide complex laser pulse shapes has growing importance in many research disciplines such as laser fusion, high-energy-density physics, laboratory astrophysics, and laser conditioning of optical materials.…
Coherent beam combining (CBC) technology is an important technical approach to break through the brightness limitation of a single laser beam, and has become a frontier and hotspot of laser technology research.…
An international team of scientific experts has gathered to examine the current status of ultra-high-powered lasers around the world and look to the future to predict what the next generation of laser systems will offer. The culmination of their work is a major review paper ‘Petawatt and Exawatt Class Lasers Worldwide’, which looks at the historical context of this technology, its current and future use, and direction.
Due to the range of size, density, and resolution demands associated with industrial X-ray radiography, there is not a source that is “one-size fits all”... Altering the source characteristics to deliver what is needed requires continued study. This publication explores the X-ray emission from spatially constrained targets compared to standard foil targets. The research results are published in High Power Laser Science and Engineering, Volume 7, No. 2, 2019 (Armstrong, C. D. , et al. Bremsstrahlung emission from high power laser interactions with constrained targets for industrial radiography.)
Intense THz radiation sources have attracted increasing research interest due to their applications in coherent and incoherent control of matter, light and electron beams.…
With the dawn of new high-power laser and accelerator facilities, modern physics was able to reach extreme states of matter normally found only in the universe or deep inside the core of our planet.…
Accretion processes are among the most important phenomena in high-energy astrophysics as they are widely believed to provide the power supply in several astrophysical objects (from stellar objects to massive black holes), and are the main source of radiation in a large number of interactive binary systems.…
Q&A with Editor-in-Chief of the Precision Medicine Journal, Dame Anna Dominiczak, for International day of Women and Girls in Science
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
The English language contains a wealth of insults and terms of abuse. Personal insults attack the core and immutable aspects of a person, such as their race, ethnicity, appearance, age, or a disability.…
Why understanding contemporary youth militancy demands history Al-Shabaab fighters patrolling Afgooye-Mogadishu road (2025) In civil war-era Somalia in the early 1990s, global media headlines about ‘stoned teenagers’ cruising Mogadishu on jeeps mounted with machine guns became synonymous with the construction of Somalia as a ‘chaotic African country’ in which one could be killed for nothing more than ‘the clothes on your back’ (New York Times, 1992).…
In January, my husband and I (Sam) took our six-year-old daughter to get a flu shot at a local pharmacy. As she became increasingly bored in the waiting room, she began to offer commentary, asking the closed door, “Doctor, when are you coming out?”…
Even though findings from genetics and other sciences unequivocally refute biological conceptions of race, this erroneous viewpoint remains widespread among the general public.…
Some disability-related names have dropped out of usage, because they are now considered to be offensive due to their origins. Down Syndrome (Trisomy 21) is one example.…

It is an article of faith among ordinary Filipinos that American troops will die with Filipino troops defending Philippine claims to the Spratly Islands in the South China Sea (SCS).…
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.
