Sadly, they note, the same degree of effort has not yet been focused on possible health effects of microplastics. Diabetes, Malaria, Arthritis: Fact or Fiction? \"Observations throughout the world make it clear that climate change is occurring, and rigorous scientific research demonstrates that the greenhouse gases emitted by human activities are the primary driver.\" (2009)2 1. (And if names like Carson and Franklin don’t ring a bell, we recommend reading Britannica’s entry Women in Science).Women scientists “who should be famous (or more famous)” implies a certain level of obscurity.

Scientists knew the location and approximate shape of the fusion peptide; however, they did not know exactly how it interacted with and penetrated into … According to Britannica:In 1934 Italian physicist Enrico Fermi claimed possible production of atomic elements heavier than uranium (or transuranium elements) after bombardment of uranium with neutrons. She met McCance in the 1930s while studying dietetics at King’s College of Household and Social Science. Jessica Hill/AP. But scientists have not yet found a planet that would be habitable by creatures like us. For scientists working with less-common species and those engaged in fieldwork, information on what exactly constitutes appropriate PPE may be very limited. Singling out 10 women to champion was of course no easy task, but we figured that this list, which consists of women from a wide array of scientific fields and who practiced in eras when science was still largely the domain of men, was a good place to start.This list was adapted from a post that originally appeared on the Britannica Blog.

Obsessed with travel? But Curie was not the first female scientist. Some scientists have raised the possibility that the increase in transmission is at least partly the result of how it infects children. The hypothesis and its supporting equation and constant, formally proposed by the two researchers in 1912–13, are now known collectively as Michaelis-Menten kinetics. American Association for the Advancement of Science\"The scientific evidence is clear: global climate change caused by human activities is occurring now, and it is a growing threat to society.\" (2006)3 2.

By Rong-Gong Lin II … The tiny fossil is unassuming, as dinosaur remains go. Noether earned a Ph.D. in 1907, having focused her dissertation work on algebraic invariants. But they’re really struggling to get a handle on what the elusive substance is. In 1915, while working at the University of Göttingen, her mathematical intuition was recognized by David Hilbert and Felix Klein, both of whom profoundly influenced the foundations of mathematics and who urged her to remain at Göttingen.
