‘Zombie’ bacteria found able to kill other bacteria
A trio of researchers with the Hebrew University of Jerusalem has found that bacteria that die as a result of silver poisoning can serve as a means to continue to kill other bacteria in the same environment. In their paper published in the journal Scientific Reports, the team describes how examination of dead bacteria revealed the silver that remained trapped inside of them and how it later caused the death of other bacteria.

A short story of a college students life
Rare Butterfly is Half Male, Half Female
This insect boasts both genders on each side of its body, making it half male, half female, new research shows.
Later identified as a Common Archduke butterfly (Lexias pardalis) - better known as the “brush-footed” butterfly - its unusual features were first realized by Chris Johnson, a volunteer at a butterfly exhibit at Drexel University.
Its two right wings were typical of the female of its species - large and brown with yellow and white spots. Meanwhile, its two left wings sported a darker green, blue and purple coloring, a pattern archetypal of males.
The strange sight is an example of a rare condition called gynandromorphy, which means an organism has physical characteristics of both males and females, resulting from a genetic mutation. It can either result in bilateral symmetry, as in this case with two sides distinctively male and female, or the gynandromorphy can be mosaic, where the two sexes aren’t defined as clearly.
