Power consumption of a home refrigerator can be cut by 29% while improving cooling capacity. Researchers replaced environmentally-unfriendly R134a refrigerant with the more energy-efficient R600a. They dosed R600a with multi-walled carbon nanotube (MWCNT) nanoparticles. Drop-in refrigerant replacement in the field by trained technicians is possible, says an engineer from the University of...
The malaria drug hydroxychloroquine, which has been promoted as a potential treatment for Covid-19, is known to have potentially serious effects on heart rhythms. Now, a team of researchers has used an optical mapping system to observe exactly how the drug creates serious disturbances in the electrical signals that govern heartbeat.
Although lymphoma is one of the most common types of blood cancer, it has a rare subtype for which no effective treatment regimens are known. For the first time, Nagoya University researchers and colleagues in Japan have conducted clinical trials for a new treatment protocol and report it to be quite promising.
