Johbu Itoh at the Tokai University School of Medicine in Japan has developed a new and highly effective cancer therapy method where cancer cells are irradiation with ultraviolet C (UVC) light.

The new method employs high intensity-UVC pulse flash rays (UVCPFR) of a broad UVC spectrum (230 to 280 nm) produced by a modified UV-flash sterilization system (BHX200). The experiments showed the pulsed nature of the spectrum to enhance the efficiency of destruction of neoplastic cells.
Importantly, the research demonstrates that under the appropriate UVC irradiation conditions only neoplastic cell were destroyed, and non-neoplastic cells did not reach conditions of cell death.
In contrast, the sterilization effects of UV pulsed flash rays (wavelengths of 230–280nm and peak wavelength of 248 nm) show promise as more efficient and rapid means of destroying a wider range of bacteria because this type of irradiation produces light whose energy is tens of thousands of times greater for a given area of irradiation, compared with conventional UV lamps (65W equivalency).
UVC pulse flash rays (UVCPFR) with 1–10 continuous flashes per second can be produced by powerful discharge of xenon gas. Johbu Itoh and colleagues at the Tokai University School of Medicine has developed and established UVCPFR therapy system for cancer therapy.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
