Non-vascular plants include two distantly related groups: 1  Bryophytes-Bryophyta (mosses), Marchantiophyta (liverworts), and Anthocerotophyta (hornworts). 2  In these groups, the primary plants are the haploid gametophytes, with the only diploid portion being the attached sporophyte, consisting of a stalk and sporangium. In these groups, the primary plants are the haploid gametophytes, with the only diploid portion being the attached sporophyte, consisting of a stalk and sporangium. 2  Because these plants lack lignified water-conducting tissues, they can't become as tall as most vascular plants. 3  Algae-especially the green algae.
It is possible that welders are at greater risk of developing skin cancer than the general population, but there is a dearth of well designed studies in this area. The only major study of the relationship between arc welding and skin cancer risk did not reveal an increased incidence of skin cancer in welders.
Scientists from Nanoprobes, Inc. claim that magnetic nanoparticles can cure cancer in just one treatment. Their findings are published in The International Journal of Nanomedicine.o, if you can deliver enough iron particles to a tumor, you can actually cook the cancer. However, translating the theory into science proved slightly more tricky. One of the main obstacles the scientists faced was that the amount of iron needed for cancer therapy was toxic to the body.
