...n that has been radio-carbon dated and shown to be alive at the same time as modern humans. The results show that modern man was not in fact descended from Neanderthals, supporting the out-of-Africa model of modern human evolution where modern humans emerged from Africa around 100,000 ago replacing archa...UNC-CH bus brings mobile lab, high-tech science focus to underserved N.C. schools

...ns were quite right. Rather, "memory" T cells stay alive for many years because they divide slowly, stimulated by a special hormone (cytokine) of the immune system, IL-15. Another immune system cytokine, IL-2, prevents this IL-15-induced production from getting out of control. Working together, IL-15 and...Pouch's newfound role tied to potential new treatment for malaria
... cells," Docampo said. "Since acidocalcisomes are alive and serve a function, we think that these drugs may kill the parasite. We haven't tested this against the malaria parasite in animals yet, but we believe these already existing analogs at least have potential in the treatment of malaria or in the de...'Scarlet E' still taints media, still distorts epilepsy
The age-old stigma against people with epilepsy is alive and well in the print media. That's the consensus of neurologists at Johns Hopkins and the University of Maryland who screened several hundred recent popular press articles on epilepsy/seizures for misinformation or outright errors.
