A first-generation college student from the Colombian coffee belt, Mauricio Sadinle deviated from the family business to pursue higher education. With help from an unlikely pen pal, he used statistics to quantify the toll of Colombia’s war with rebels. Now, he uses statistics to improve the quality of data and to unlock data's full potential.
An international group of researchers used the trial data to compare vaccine efficacy and cholera risk between three different age groups: children younger than 5 years, 5 to under 15 years, and those 15 years and older. The research team included biostatisticians from the University of Washington School of Public Health and Fred Hutchinson Cancer Research Center.
Homo sapiens had lots of sex with Homo neanderthalensis. Neanderthal genes supply between 1 percent and 4 percent of the genome in people from homelands on several continents, from Britain to Japan to Colombia.DNA from another human-like primate, the Denisovans, lurks in modern genomes, too.
Humans weren't just making babies with Neanderthals back in the day. A new study that compares the genomes of different groups of modern humans has found that our ancestors interbred with another close relative, the Denisovans, more than once.
