Cancer therapy in recent times relies on the use of several drugs derived from biological sources including different bacteria and viruses, among others. However, these bio-based drugs get easily degraded and therefore inactivated on administration into the body. Thus, effective delivery to and release of these drugs at target tumor sites are of paramount importance from the perspective of cancer therapy.
Recently, scientists have discovered unique three-dimensional, water-containing polymers, called hydrogels, as effective drug delivery systems (DDSs). Drugs loaded into these hydrogels remain relatively stable owing to the network-like structure and organic tissue-like consistency of these DDSs. Besides, drug release from hydrogels can be c
Renewable hydrogen systems manufacturer Ways2H Inc. and its shareholder and technical partner Japan Blue Energy Co. announced the completion of a facility in Tokyo that will convert sewage sludge into renewable hydrogen fuel for fuel cell mobility and power generation.

News comes from the Land of the Rising Sun that a first-of-its-kind Tokyo facility will convert sewage sludge into renewable hydrogen fuel is now complete. Ways2H Inc. and its shareholder and technical partner Japan Blue Energy Co. say the waste-to-hydrogen facility will process 1 ton of dried sewage sludge per day, to generate 40 to 50 kilograms of hydrogen per day, enough to fuel 10 passenger vehicles or 25 fuel-cell e-bikes. And in case you didn’t notice, this year’s Olympic torch left Fukushima a little over a week ago fueled with, yep, you guessed it – hydrogen!
Today (31 March) marks 70 years since the world’s first commercial computer was unveiled.
The Universal Automatic Computer I (UNIVAC I) was the absolute state of the art when it was unleashed on the world in 1951, even if some of its capabilities seem one step away from pen and paper compared to modern computers.
However, the massive UNIVAC’s introduction on 31 March 1951 ushered in the future of commercial computing.

Fun facts
Even though the UNIVAC’s power was relatively modest, it didn’t stop people from worrying about the dangers of machines that could one day take over their jobs.
