hahn and strassman showed that elements with an atomic number below 90 could be split apart by bombarding the elements with higher energy particles, but many nuclear scientists developed cancer as a result.

otto hahn and fritz strassman discovered nuclear fission by bombarding uranium with neutrons, but it was their colleague lise meitner who was able to explain why barium was found as a product in their research.

lise meitner had been a physicist in her native germany until 1938, when she was forced to interrupt her research and flee because her jewish heritage made her a target of nazi persecution there.

after lise meitner received word from otto hahn, she consulted with her nephew, otto frisch, a fellow physicist and suggested that the fission of uranium was the cause of the presence of barium atoms.

Bisphenol a (often called bpa) is a chemical found in products that people use every day, from water bottles to food containers to children's toys. unfortunately, bpa leaches out of its many products and makes its way into our bodies. what are the health effects of bpa exposure? ongoing research is finding that elevated exposure to bpa can affect a wide variety of developmental and physiological processes, but one of the first studies of bpa's health effects came about because of a simple mistake in the lab. at a laboratory at case western reserve university in 1998, geneticist patricia hunt was making a routine check of her female lab mice. as she extracted and examined developing eggs from the ovaries, she began to wonder what had gone wrong. she noticed that many of the eggs showed problems with their chromosomes, and some had irregular amounts of genetic material, which can lead to miscarriages and birth defects in mammals. she learned that a lab assistant had mistakenly washed the plastic mouse cages and water bottles with a harsh soap, releasing bpa from the plastic. knowing that bpa is an endocrine disruptor, a chemical that can enter organisms and mimic hormones, hunt set out to discover whether it had adversely affected her mice.
