How do you gauge the magnitude of a series of lion attacks that occurred over a century ago? In 1898, construction on the Ugandan Railroad in East Africa was halted due to deadly, nightly lion invasions that took the lives of Indian and African laborers who were working on the project. By some estimates, over 100 people had been devoured by these animals, hungry because drought and disease had reduced the number of natural prey. But researchers at UC Santa Cruz published a report this week that gave a more accurate estimate of how many humans the two male lions really ate. They did it by running chemical tests on their carcasses:
Bones and teeth store carbon and nitrogen isotopes over long periods, while the ratios in hair change more rapidly, allowing the scientists to determine the long-term diet and how it changed in the lions' last months.
Humans made up at least half of the diet of one of the lions in the last months of his life, consuming at least 24 people, they concluded. The other lion had eaten 11 people, they found.
In other words, even a century later, you are what you eat.
In 2013, Gregory Sutton from the University of Bristol published an important paper demonstrating that bumblebees can sense electricity (his experiment trained bees to associate current in fake flowers with nutrients, and showed that bees preferentially sought out electrified flowers), but now how they sensed it.
NASA today announced that astronomers studying data from NASA’s Great Observatories have found the best evidence yet for “cosmic seeds in the early universe that should grow into supermassive black holes.”
Could you recover a murder victim’s last sight of their killer by extracting it from the retina? Little more than a century ago, forensic scientists thought it might be possible. After all, in 1877 physiologist Wilhelm Friedrich Kühne was able to develop a simple image from an albino rabbit’s dissected eyeball. (Above, the two images […]
