Although the standard approach to acute appendicitis is to remove the appendix, a study at the Sahlgrenska Academy, University of Gothenburg, Sweden, reveals that treatment with antibiotics can be just as effective in many cases.

This shows the spiney-type insect. Writing in the journal PLoS One, the scientists have used a high resolution form of CT scanning to reconstruct two 305-million year old juvenile insects. Without the pioneering approach to imaging, these tiny insects – which are three-dimensional holes in a rock – would have been impossible to study.

Ants that are held as slaves in nests of other ant species damage their oppressors through acts of sabotage. Ant researcher Professor Dr. Susanne Foitzik of Johannes Gutenberg University Mainz (JGU) in Germany first observed this "slave rebellion" phenomenon in 2009. According to the latest findings, however, this behavior now appears to be a widespread characteristic that is not limited to isolated occurrences. In fact, in three different populations in the U.S. states of West Virginia, New York, and Ohio, enslaved Temnothorax longispinosus workers have been observed to neglect and kill the offspring of their Protomognathus americanus slavemakers rather than care for them. As a result, an average of only 45 percent of the parasite's offspring survived. This presumably reduces the strength of the parasites in the area and thereby increases the chances of survival for the neighboring colonies populated by the slave ants' relatives.
